United States Air Force Museum Replica Collection


Recommended Posts

My sincerest apologies for not posting earlier. 

 

Two weeks ago, the museum turned 100 years old and opened its Centennial Exhibit to the public. It showed how the museum evolved from an aviation engineering showcase in 1923 to the largest military aviation museum we all know and love today. Feel free to check out the post I made below for some more details.

  • A photograph I took of the Centennial Exhibit at 9:05 AM on May 21st. I was the first one from the general public (at least for that day) to walk through it.

 

  • The video that was playing on loop in that exhibit. You can find it in the Air Force Museum's YouTube channel.

 

Now that the warm-up act is over, on to the main event. If you joined the Air Force before 2009, you'll remember having to train in a T-37 Tweet.

  • Also known as the A-37 Dragonfly.

 

rFX9KXC.png

  • The Cessna T-37 Tweet on display in the SPH.
  • I am aware that the real-life counterpart had a crew capacity of 2, but I went for manufacturing simplicity as well as looking like its namesake.
    • The few replicas of the Dragonfly I found on KerbalX look a bit hard to make and messy.
  • Since my KSP headcanon would have this plane be a pre-Famous Four jet trainer, this didn’t have a probe core. Later variants, especially those equipped with modern avionics, would have those.
    • Installing a fly-by-wire would require a longer nose, so I went with a regular nose cone with a retracted antenna sticking out of the end.

  • "WHO IN GOD'S NAME AUTHORIZED JEB TO SET ONE TOE IN THAT COCKPIT?!"
  • Jeb buzzed the tower after taking off at a mere 40 m/s. Understandably, this ticked off everyone in the tower.

 

S2LFKqY.png

  • Jeb flying away from KSC after tuning out ATC (while they were chewing him out for that stunt he pulled). 
  • Instead of flying west towards Alt Test Mountains, he chose to fly northwest.
    • "Hey, if it can get over 5 kilometers altitude, it has a decent shot of going over the mountains."

 

EZEQVjm.png

  • Apparently, flying northwest would come with its fair share of beautiful sights.

 

79kZATa.png

  • After 45 minutes of continuous flight, Jeb managed to fly 600 km before he needed to land.
  • The KSP replica's cruise performance stats were as follows:
    • Altitude: 8.55 km (~28.1k ft; Class Alpha airspace)
    • Velocity: 230 m/s (~515 mph)
    • Takeoff Speed: 40 m/s (~89.4 mph)
      • 77.8 knots for you IRL pilots
    • Range: 600 km
      • The real-life T-37B could fly 1,046 km

 

QhnzunO.png

  • Jeb running away before he could be caught with the plane. When local police found him not long afterwards and dragged him to the KAA to face consequences for his tower buzzing, he sure got in a lot of trouble.
  • When the plane was recovered, it had 5.71 fuel units left - and not a scratch on it.
    • It started out with 145 fuel units, and was burning at a rate of 0.05 (later 0.04) while cruising.

 

Any and all help in completing the list would be nice. Perhaps I should make a badge for those who contribute to this thread, with a fancier-looking one for those who add at least one plane from each of the four hangars.

  • I need to know how to counteract the rolling so I can make stable single-engine prop planes, by the way.

  • 3 weeks later...

Ladies and Gentlemen, boys and girls, live from above the jungles of 'Nam, the B-52 Stratofortress.

 

QQgKcYS.png

  • The B-52 on display in the SPH
    • It has the basic look: eight jet engines, long swept wings near the top of the fuselage, a bomb bay, and a conventional tailfin.
  • Due to the engines being connected to the aircraft’s structural pylons via a M-1x1 structural panel, they’re cut off from the fuselage’s tanks and have to rely on the cylindrical Mk. 1 tanks. In other words, any fuel I put in the fuselage’s tanks is dead weight and my range is reduced.
  • I didn’t add any bombs - or anything to act as ordinance - to this one. I didn’t have BDArmory (anymore), and I wanted to see how well it would do without that extra weight. If you want to modify it to carry weapons, go ahead.

 

If you know a way to maintain the B-52 look while allowing the engines to use the fuselage tanks, I’d like to hear about it please. Thank you in advance if you do.

 

9dGOacX.png

  • The B-52 flying west at night. In hindsight, I should have waited until sunset to take off.
  • For this test, since the real-life B-52 was a subsonic bomber, I decided to leave the afterburners OFF. I could go faster and fly higher if they were on, but it would probably come at the cost of range.
  • Without Kerbnet, I couldn’t really see what was underneath me, which meant it would be hard to find a suitable landing spot when I was very low on fuel.
    • Which is why I should have waited until sunset to take off for a westward flight.

 

TG7wt1J.png

  • 12 fuel units left per engine, leaving 96 usable fuel units left, and I need to land. I had to use the exhaust to see if I was over land or not, and I was lucky to have been over (I think was) some peninsula.
    • Like I said earlier, the fuel tanks in the fuselage were no good (except for moving the CoM), so all I could use were the eight Mk. I Lf tanks - with one per engine. I had to right-click on one of those tanks to accurately see how close I was to empty.
      • Right now, there’s only 3,200 fuel units usable when ready. The other 750 units in the back are the dead weight.
  • When I turned on map view after landing, I noticed that I was halfway around the world.
    • After further testing with the MJ rover autopilot, I then realized that I've been calculating my ranges incorrectly the whole time.

 

  • The KSP replica's cruise performance stats were as follows:
    • Afterburner: OFF
    • Altitude: 9.9 km (~32.5k ft; Class Alpha airspace)
    • Velocity: 220 m/s (~492 mph)
    • Expected Range: 1,885 km
      • Assuming it can still fly that far when loaded with ordinance, if it’s a two-way bombing mission, you’ll need to half that expected range if you want to land at that same airfield - with some fuel left to spare since you’ll be shedding weight after you blow up some enemy bases.
      • The real-life B-52D can fly 13,419 km unrefueled 
        • For reference, the circumference of the Earth is approximately 40,075 km

 

fTprFaY.png

  • Photograph of Amelia Kerman, Jeb’s (late) mother, doing a pinup pose on the nose of a B-52 bomber.
    • Picture taken by her boyfriend, Jebediah Jeb Kerman (Senior), after they snuck into a hangar for a daring date. Eventually, the pair would get married and have two kids, Vanessa and Jeb. Unfortunately, while Jeb (Junior) was only a baby, Amelia and Vanessa died in a plane crash caused entirely by Amelia’s utter disregard for flight safety.
    • Jeb Senior kept a framed poster-sized copy of this picture at his house in Baikerbanur, in a small room he turned into a memorial for his wife and daughter.

 

AyliVux.png

  • Another flight test. This time, the bomb bay doors were open - but the plane itself is unarmed.

 

Wow, my first Southeast Asia section entry. Maybe I should learn how to make helicopters for my next one*; we shall see. If you want to join my quest to replicate the entire museum, which I repeatedly stated I couldn't do all on my own, that'd be awesome. I promise to have a badge ready for you by the time of my next entry here.

  • And if that's too hard, I could always stick with the simple jets.

 

As for my range problem:

Spoiler

I just realized today that MJ takes the straight-line distance between waypoints in the aircraft and rover autopilots. In other words, whatever number I see is the distance I would travel if I went straight through Kerbin's surface. This is apparent by the fact that MJ's aircraft autopilot marked me as "1.2 Mm" away from the KSC and yet I was already halfway around the planet. Since Kerbin has an equatorial radius of 600 km, it stands to reason that the 1.2 Mm I read was the full diameter, which led to the straight-line distance conclusion.

 

I also realized that if I wanted to see how far I can go along Kerbin's surface, I need to use more than just what MJ's aircraft autopilot tells me. Rather, I need the length of an arc. 

 

Think of my travel path along Kerbin as a disc below, with "MJ Dist" being the distance that MJ gives me (whether it be measuring how far away I am from the KSC or any other waypoint).

F32RbsS.jpg

 

To get the distance traveled along the surface, I:

  1. Split the isosceles triangle seen above into two identical right triangles.
    1. "MJ Dist" divided by two on one side.
    2. 600 km (or whatever the equatorial radius of your celestial body is) on the second side.
    3. The third side doesn't matter.
    4. Theta is divided by two in each right triangle.
  2. Obtain the value of theta (in degrees) by:
    1. {arcsin [(MJ/2) / 600]} * 2
      1. If you're airborne, you might want to subtract your altitude from the given "MJ" value
        1. e.g. I'm getting a reading of 1.209 Mm from the KSC, but I'm ~ 9 km high.
    2. The split triangles from earlier make it easier to visualize what you're going for. First, you get theta/2. When you put the two triangles back together, you get the full theta.
  3. Obtain the short arc length by:
    1. 2 * pi * 600 * { theta (degrees) / 360 }
  4. (IF YOU FLEW PAST THE HALFWAY POINT) Substract subtract your result from Step 3 from Kerbin's circumference (2 * pi * 600).

 

If I'm wrong on how to calculate distance traveled (assuming a straight line), please tell me.

If this is right, I plan to make an Excel sheet made specifically for this task.

You can attach the Mk1 nacelle tanks directly to the pylons, as if you're making a single nacelle assembly, but then rotate them by 90 degrees (one clock-wise, one anti-clockwise). At most, you may need a tick or two of offset to make them look properly attached as a dual-nacelle assembly. The pylons will need to be set to 'enable crossfeed' to allow fuel in the rest of the plane to be used, since that's not the default setting.

Pulling them heart-strings again, why don't you. Mutter. Fine.

 

Here's a replica of the Convair XF-92A as displayed in the R&D section of Hangar 4 of the USAF Museum.

Spoiler

QZxrDDB.png

The Convair XF-92A, a prototype "point-defence interceptor", first-generation jet fighter, testing the concept of a thin high-speed delta wing.

fB8MiZF.png

Despite being a candidate for a supersonic plane, it never managed to perform to that level. The wing however proved to have excellent characteristics.

vv57yUX.png

Jeb of course had to outdo Chuck Yeager's mach 1.05 dive in this plane, reach mach 1.17 in the same split S maneuver.

qSPYOk1.png

He also had to find out the hard way that this plane is capable of very high G turns if one is not careful with that back stick.

 

Just like the original prototype, this one was built with high constraints on time and budget, so it's a very simple build using pure stock parts only.  And like the original, it's quite a tricky plane to fly - but if you take the time to accustom yourself to it, quite fun actually (as opposed to the original).

One more marked off the list?

Yes, thank you very much. I also liked the part where you copied Yeager's dive in an attempt to breach Mach 1, but could only achieve it during that short a period (just like in real-life).

  • Also, where did the G-limit warning come from. I don't have it on my sandbox save.

 

It's great that you've been dabbling into the experimental planes, even though they turned out failures. Guess I shouldn't expect much if I attempt to copy the X-4 Bantam - again. However, if you want this cool badge to add to your signature (see my OP for the larger version), you'll need at least one plane from all four hangars.

This is mainly for @swjr-swis, but this also applies to everybody else too.

 

I call dibs on the X-4 Bantam since I managed to get a working prototype on KSP1. I just need to post it on KerbalX (after sleeping, eating, working, and exercising IRL) before I show it on this thread tomorrow. Below is a sneak peek of what to expect.

 

G1bD7YV.png

 

You'll all get full details of this aircraft's performance tomorrow. So, if anyone feels guilt-tripped about making more replicas, at least let me have this one please. I'd rather not my work turn out to be for nothing because someone had beat me to it while I was busy.

  • I mentioned swjr-swis specifically because he made the most planes from the Research and Development Gallery - and I mentioned the X-4 in a post replying to him earlier.

 

Thank you all very much, and fly high.

It's a non-default setting of a game save, enabling G forces on Kerbals - you have to go into the save settings (or game settings when in the save) to enable it.

One of the few things that are actually fully implemented in the game and working perfectly as far as I've noticed, and it's disabled by default :rolleyes:.

This is mainly for @Mars-Bound Hokie, but it applies to everyone else too: I sincerely hate stock props. Ugh, with extra phlegm.

That said, since I was advised I *had* to do a plane from hangar 1 as well and there's only props left from that section, here's my attempt at a Douglas C-47D Skytrain, a turpoprop transport plane displayed in the hangar 1 world war II area.

Spoiler

wWbBfmI.png

2qydas3.png

kmu1NV6.png

Some artistic freedom was taken with proportions and size ratios to allow a build in stock+ (BG) parts. I think it still mirrors the characteristics of the original, if I say so myself ("Did you really?" "Yes, I think I did." "How quaint. Now stop talking to yourself").

It does perform slightly better in KSP than the real life version, and is quite relaxed to fly once in cruise, but I get too aggravated by the constant micro-managing required to get reasonable performance out of the engines/blades through any flight to enjoy it much. For those who like that sort of thing: enjoy.

As seen in the previews, here's our entertainment for the night. Presenting the X-4 Bantam.

 

sm26RSl.png

  • The X-4 Bantam on display in the SPH. Since this is an experimental plane, it comes with a parachute in case the test pilot was dumb enough to forget his own.
  • The ailerons weren’t any help in me getting off the runway; they kept moving in the opposite direction, in fact. Even when I pitched down on the controls in an attempt to get up, it got airborne for almost five seconds before it went on an irreversible dip.
  • To give this plane some pitch while maintaining the look of a wingless experimental aircraft (that turned out lame), I hid canards near the front ends of the wings. Subsequent testing proved successful, and you can barely notice the clipped canard. At least the plane’s functional, but (just like in real-life) don’t expect much.
  • I was split over using the standard SPH shot angle or recreating this photo from the X-4’s Wikipedia page. In the end, I decided to maintain uniformity.

 

cnKq6ge.png

  • Finally, a successful takeoff.
  • Seymour Kerman, when he tested this (would-be failed) prototyped a long time ago, decided to fly north. Though it was procedure then to fly west to see if aircraft would go over Alt Test Mountains, Seymour had expressed concerns beforehand that the Bantam would not make it that high.

 

XLYYGOv.png

  • The X-4 cruising north, with this shot looking just like the picture of the real-life X-4 on the runway. Surprisingly, though the plane’s altitude and cruising speed aren’t that good, it was able to maintain a straight-and-level flight path.

 

t0htA7w.png

  • Seymour having to break cruise to go around the mountains up north - kind of like a trench run.

 

bIQvkwg.png

  • For a plane that was an experimental transonic tailless fighter, it’s got quite an impressive range if it can fly over Kerbin’s north pole.
    • It’s also a nice shot of the northern lights.

 

A notable moment in aviation testing history was when at the time this plane crossed this point, Seymour Kerman’s mother ran into the ATC room and screamed to warn her son about something.

  • WOMAN AT ATC: "Seymour, your plane is on fire!"
  • SEYMOUR KERMAN; X-BANTAM: "No, mother, it’s just the northern lights."

 

G1bD7YV.png

  • Nighttime or daytime? Around here, who knows.

 

HO9kjvn.png

  • 7.26 units of fuel left, and Seymour is halfway around Kerbin after nearly 2 hours and 20 minutes in a polar flight.

 

The KSP replica's cruise performance stats were as follows:

  • Altitude: 4.5 km (~14.8k ft)
  • Velocity: 230 m/s (~514 mph)
  • Expected Range: ~1,880 km
    • The plane was flying on fumes when it reached the halfway point around Kerbin, so it's best not to push it.

When it comes to gas-powered prop engines, I agree. Besides aesthetic, making replicas of old aircraft, and making something for your KSP fanwork-verse (both of which would relate to the "aesthetic" reason), they have no real purpose. Who even needs helicopters to fill out land survey contracts on Kerbin, anyway? Electric-powered rotors, however, do have their uses. 

 

@swjr-swis, I will admit that I'm still struggling to get your C-47 replica to cruising altitude and speed, but thank you for providing a replica that works. At least knowing the general concept of the structure, I (and others) will know what to aim for when making larger old planes. That's three hangars now you have under your belt. Only one left from Hangar Three before you qualify for the All Four Hangars Badge, and those planes look very easy to copy on pure stock.

  • And don't worry about me stealing something you want from there, since my next target is something from Hangar Four.
    • You'll find out what and why when I post it.
    • After that, if I ever master making helicopters, my target after that will be from Hangar Two.
      • If I can't do that, then I'll bite the bullet and copy something from Hangar One.

 

Thank you all for helping out.

Easiest way is to point east, set SAS ORB (!) PRG, and punch the throttle (my standard rapid iteration test for planes).

This will make the plane perform a near-optimum climb envelope, leaving the pilot to concentrate on managing the blade deployment and -later- throttle. It does take a while - 10 min or so to settle at 7000 m at 135 m/s and slowly climbing/accelerating further. Considering the original took 9m30s to get to 3000 m and 100 m/s, the replica does pretty well.

Obviously this only works on a due east course, but it'll prove the capability if you wish to see it. Plus, not needing to manage the stick (on top of the props) it offers the possibility to observe climb angles along the path when you want to replicate it with manual trim or autopilot mods on any other heading.

The ailerons' rotation axis  points right through or even ahead of the CoM. KSP's code doesn't know how to handle that, especially when combining roll and pitch on the same control surface. Standard result of such a situation is exactly what you describe, basically the plane constantly fighting your pitch and/or roll attempts.

Spoiler

Your craft, with some adjustments. No canards and no control issues.

Cheated a bit on this one, picking the next-to-easiest option from hangar 3 hangar 4: the Gemini B capsule.

zXOdIoQ.png

Craft file is as shown here. I decided to replicate the museum showpiece, as the Gemini B / MOL program was cancelled before it ever flew.

 

In my defense, I did not simply plop down the capsule, I did try to include all visually identifiable elements and whatever functionality I could find documented. And I went and did a decoupling from the MOL and reentry test, which is more than the original ever did (the 'B' anyway).

Spoiler

KKPWm7n.png

The Gemini B in the SPH.

13epXpi.png

Opposite angle shows the most marked differences with the NASA counterpart: the larger heatshield (due to the polar orbit) and the hatch that would allow passage into the Manned Orbital Laboratory.

IFSWmUb.png

The assembled MOL and Gemini B capsule as intended in orbit, lifted by a Titan IIIM ICMB launch vehicle. In reality a classified orbital reconnaissance and surveillance station.

MozBxqn.png

The capsule would use the same reentry method as the NASA Gemini.

It was never actually flown as the program was cancelled, but NASA's version did fly and prove the concept.

First of all, that is not a Hangar Three craft. That's from Hangar Four, which contains the Space Gallery.

 

Second of all, I did say that:

  • any and all parts, including DLCs and mods, were fair game.
  • the vehicle has to be functional unless whatever was displayed at the museum could not move on its own.
    • so if just the capsule was there, the functionality requirement would be waived and just a stationary capsule would be fine (like with my Apollo 15 capsule replica).
  • the craft has to look as close to its namesake as possible - and you nailed it.

 

So it's not really cheating so much as it was seizing the chance at an easy shot at a replica.

 

Speaking of easy shots, third of all, Hangar Three has a lot of planes that look easy to copy - like the F-15 (or its Russian twin the MiG-29), U-2, or the A-10 to name four. I'll also (technically) accept another F-86 since the showcase grants an exception to the "no claiming any duplicates" rule for craft that appear more than once throughout the museum (e.g. F-82, B-29).

  • So if you go the F-86 route, as long as you're the one who made it there should be no problems.
    • Its Soviet ripoff, the MiG-15

 

Fourth of all, great detail you put into this - even down to the display stand. And nice story to go with the mission photo gallery too. Though you got the hangar number wrong, thanks for checking this off the list. As for me, I'm testing a Hangar Four replica as I type this post. It's been airborne for over three-and-a-quarter hours now, and it's already past the third-quarter point around Kerbin. So start packing your footlockers, because the plane arrives tomorrow.

Ok, I double-checked this time, it's absolutely listed -at the very bottom, but still- under hangar 3 (*) this time: the Thor Agena-A obsoleted-ICBM-turned-lifter-vehicle.

di37NXM.png

 

Not as easy to create as it may appear on the surface. Not only because of missing many analogue parts in the stock+ selection, but also because one is confronted with the choice of building either a ludicrously overpowered -but matching in size- rocket, or one that performs similarly to the original but necessarily has to be significantly downsized and/or handicapped to make it so.

For this one, I chose to follow the second strategy: rocket dimensions are a good bit smaller, and  engine and fuel capacity have been tuned down, while trying to keep as much of the outer appearance and the functional performance.

The early Thor Agena-A launches carried the classified CORONA C high-res photo satellite, which returned only a tiny reentry vehicle containing the film. I haven't been able to find a whole lot of detail of either the lifter stages nor the satellite, probably because of the long-classified nature. The few pictures and schematics available online are somewhat lacking in detail, so I've had to fill in the blanks at my own discretion.

I hope this is an acceptable result.

Full album and textual commentary: https://imgur.com/a/rWpAkGI

 

*: as it turns out, it's not actually in hangar 3, but in an area between hangars 3 and 4. Spreadsheet and OP were updated to reflect this.

A wise man once said "A good soldier never leaves a man behind."

  • Not only does following this mantra reduce the amount of manpower and equipment wasted, but it's great for morale. If you end up wounded, lost, or captured, you can count on your brothers-in-arms fighting tooth and nail to bring you back; sometimes it means fighting their own superiors. In the unfortunate event you do lose your life, they'll still fight to bring you home.
    • Don't expect all the higher-ups to be as eager, though, but that's another story I'd rather not share in a forum for spacefaring game-players and flight enthusiasts.

 

I do not intend to start now, which is why I built this replica of the C-141 Starlifter.

 

uK7MgpD.png

  • The C-141 Starlifter on display in the SPH.
  • I included "Hanoi Taxi" in the craft name since it's the most famous C-141 used (as far as I know). If any aviation or history enthusiasts are looking for the Hanoi Taxi specifically - or just happen to come across it - it would make it easier to find on KerbalX. 
    • For those who don't know, the “Hanoi Taxi” (serial number 66-0177) is a C-141 used in the repatriation of American POWs from Vietnam during the conflict's closing days. 
    • The plane in question is currently on display at the National Museum of the United States Air Force in Dayton, Ohio.
  • The fuselage is nothing but cargo bays with external command seats inside arranged in four lines - each fifteen seats long. This is to maintain the image of a real-life empty fuselage with seats installed, just like with the real-life Hanoi Taxi. It also looks way smoother than a cargo ramp that leads up to four Mk3 passenger modules - and given that I ended up with a passenger capacity of 60 as opposed to 64 (plus the 4 crew in the cockpit either way), that’s not a bad trade.
    • It also has a ladder leading up to the back door of the cockpit from the "passenger cabin" (or cargo bay, depending on how to look at it) so kerbals can get in and out of it
  • If you want to modify this plane to carry nothing but cargo, feel free to remove the seats as necessary. Although I wouldn’t say no to this being used as an airliner either - especially one with no class division. Everybody rides coach, after all.
  • This plane has multiple separate SEQ-3C Conformal Storage Units lined up in the fuselage. Most of them are empty, but the two units in the rear each have four EVA kits and large work lamps. The cockpit has eight repair kits and a couple of small work lamps in the highly (opposite of) unlikely event the plane takes damage during its mission.

 

uAvimTl.png

  • Historic photograph of recently-released POWs in a Starlifter before taking off.
  • Although the photographer was competent at his job, he often had trouble keeping his camera still while the plane was moving. Especially with a plane not designed for comfortable rides.
  • Nobody named Jane was on board this time - mostly because all the plane’s passengers and crew for that mission were men.

  • Ladi… um, gentlemen, before we begin our safety presentation, please rise and salute the flag for the playing of our National Anthem.
    • Why wouldn't I put that flag there?

  • The Starlifter doing its best to stay at cruising altitude and speed. At first with MJ aircraft autopilot on, it was bouncing up and down a bit. Eventually, it managed to keep straight and level.
  • Whatever you do, DON’T time warp. Otherwise, your flight will get bouncy (at least mine did during the warp) and you’ll waste fuel.

  • 400 km away from the KSC, and that is where I made my range estimate.
    • On Hotel26’s recommendation, I used the equation below to calculate how far I should expect this plane to fly.

  • The range calculation done on Symbolab. The complete flight test proved this estimate to be more conservative (as in leaving some leeway), but not too far off.
    • Especially since I had to make a turn later (stay tuned for the full story).

 

Nothing beats actually flying and landing the thing, sure - especially when determining if you need to set up fuel flow priority in order to maintain balance during landing - but this equation proved useful. This can come in real handy if you’re under a real-life time crunch, like if you need to go to bed.

The KSP replica's cruise performance stats were as follows:

  • Altitude: 7.9 km (~25.9k ft; Class Alpha airspace)
  • Velocity: 260 m/s (~582 mph)
  • Flight Time: 3 hours, 30 minutes
  • Expected Range: 3,250 km
    • DO NOT fly over water when this happens
    • More details on how I calculated the range in the spoiler below. If you're not interested, feel free to skip it.

  • And this began how I determined the plane’s range despite having to make a turn.
    • First test run ended up with me over water when I ran out of fuel. Fortunately, I had set up a quicksave before I went over the coastline ahead of time. So, all I had to do was revert to that quicksave and turn south so that I would be over land.
  • Using MJ’s rover autopilot, I set up a waypoint at my plane’s longitude but its latitude would place it at the equator. That way, I would use trigonometry to see how far I was (straight-line distance) from the KSC when I made my turn. For future reference, the "distance-at-turn" value will be r.
  • I then used the Law of Cosines and arc length to determine the ground distance on Kerbin from the KSC along r. Since I had already passed the halfway point, I subtracted that value from Kerbin’s circumference - and got Rarc = 3,122 km.
  • As for the ground distance covered after making my turn, I used the Law of Cosines on Kerbin again. After that, I used arc lengths (and accounted for altitude) to get Tarc = 128.4 km.
  • Put Rarc and Tarc together, and you get an estimate of 3,250 km flown.
    • Less than 100 km off what my predicted range would be.
    • Although I doubt that the plane having such a range is necessary, given that you only need 1,885 km to cover anywhere on Kerbin.

@swjr-swis,

Well, technically the missile silo isn't part of any hangar - just between Hangars Three and Four. Since there are only seven left in that category (eight counting the one you just did) and to avoid further confusion, I'll specify in the OP that, for the purpose of qualifying for the All Four Hangars badge, Missile Silo entries are (ultra-rare) "wild cards" that can be either a Hangar Three or Hangar Four entry depending on what you lack.

  • So, for everyone else, use it while you can.
  • I'll also add a "One wild card per person" rule so nobody hogs them all (or tried to "cheat" by having two wild cards to fill in the Hangars Three and Four slots), but I might end up lifting it later.

 

In a nutshell, you've earned the All Four Hangars badge. I'll also put your name in the Hall of Fame. If you want to continue making replicas, go ahead. :1437623226_rocket_1f680(3):

  • I thought about calling it the "Wall of Honor," but you (kind of) have to be dead to qualify for something named that.

 

To everyone else reading this, now you have something (high) to aim for. 

 

Replicas Remaining: 226

Ah, another technicality. The bane of my existence. I've never been to the museum myself, and the linked spreadsheet listed it in the hangar 3 section. I thought I got it right that time.

I'll have to come back and do one from hangar 3... this time for real real.

 

Btw, have you considered starting a KerbalX hangar for all the replica's of this thread?

No, it didn't. It was separated quite distinctively from the other hangars, as seen in the screenshot below. 

 

KHm1GCC.jpg

  • There was no hangar number assigned to the Missile Gallery, and it was separated by a thick black line. It was its own section on the list.
    • Maybe I should have been a little more clear at first.
  • Revealing information like my initial and weather were blocked in this shot..

 

Regardless, since there were only eight possible craft (seven now) one could make from the Missile Gallery, they're now wildcards that can be used as either a Hangar Three or Four entry. I can't wait to see your (non-wildcard) Hangar Three entry, though. It shouldn't be too hard. Either way, you're qualified for the All Four Hangars Badge.

If you're in or near west Ohio (or are visiting someone there), or don't mind the road trip from somewhere farther away like Cleveland or Louisville (KY), it's definitely worth checking out. For those who cannot make it and/or haven't visited recently, here's the current general layout of the museum.

 

rVskrMk.png

  • As you can see, you have to go through the Missile Silo if you want to get to Hangar Four.
  • I mentioned people who haven't been there recently because Hangar Four wasn't built until 2016, so they may not know about it or what's in it.
    • Depending on when they last visited, they may not know about Hangar Three either.

Technically, I already have a replica hangar - just not for all of the craft on this thread.

  • All the craft in it are mine, as in I built them.
    • Nobody else's craft is in it.
  • It includes the F-35, which is not in the museum, and craft from:
    • The Incredibles movie (IG99 - the plane Mrs. Parr flew to Nomanisan Island in)
    • Phineas and Ferb (Doofenshmirtz Evil Incorporated)
    • The album cover of Club Ninja from Blue Öyster Cult (That freaky-looking space station)
    • The guitar-shaped UFO in Boston's album covers
      • So, basically, I include copies of not only real planes (especially ones not in the museum), but craft from album covers and movies/TV shows.
        • Side note: I tried making a model of Star Command from the Buzz Lightyear of Star Command show, but the rocket kept failing before breaching the atmosphere.

 

You're right, maybe I should start a KerbalX hangar for the replicas in this thread (the ones that are even on KerbalX, that is) - including the ones not made by me.

--------------------------------------------------

UPDATE: just started one: https://kerbalx.com/hangars/167846

  • Doesn't have my Apollo 15 capsule or shuttle because I never posted them on KerbalX since making them was far too lazy.
    • By the way, if I am going to post a shuttle replica, I'm including everything else that comes with it.

When you hear the words "flight simulator," the first thing that pops into your head would be:

  • machines that look like arcade games - and in some cases are arcade games
  • videogames such as MS Flight Simulator or X-Plane that need extra hardware to work
    • or computers with said hardware that you'll often find in brick-and-mortar flight schools or museums or similar venues.
  • computer programs like Google Earth or GeoFS
    • which are great for cheapskates and/or those short on space

 

90 years ago, if someone interested in flying heard those same words, odds are they'll think of the Link Trainer (also known as the Blue Box)

 

iWbuMjW.png

  • Historic footage of a student pilot learning to fly in a Link Trainer with an instructor checking his progress (both student and instructor unknown). Picture taken six years before the Second Imperial Wars broke out.
    • This came in real handy when the war did happen, as Heinkel's enemies in the air were experienced "flying blind" - giving them an advantage.

 

Now imagine listening to this in the voice of the guy who narrates those old black-and-white PSAs:

Spoiler

When Kerbalkind first took flight, they had to rely on what they saw around them to navigate. Great if you have a keen eye, but not when it gets dark or if the weather gets too bad to see anything. This is where Link Kerman’s new invention, the Blue Box, comes in.


In here, a student pilot will be enclosed in total darkness, simulating what it is like to fly without visual references to guide him. He will have to rely on his cockpit instruments alone if he is to get to his destination safely. Opposite of him, his instructor will give him orders and check his progress at a desk connected to the Blue Box. On that desk is a device which draws the student’s flight path on a map, a duplicate of the student’s instruments, and a machine to simulate wind direction and speed on the pilot. After all, top-tier pilots do not let mild inconveniences such as wind stop them from carrying out their duties.


When this pilot is done, he will go on to deliver mail around the world.

 

AUfBySD.png

  • The Link Trainer and the instructor’s desk on display in the SPH.
  • It was difficult deciding what motors to use and in what order, and I had to look at my old swept-wing jet to figure out how to set up the action groups. In the end, I managed to set up the motors to obey the main steering control inputs.
  • Since the pilot would be flying in complete darkness, I disconnected the cockpit lights from the main light button. The two small lights on the fuel tank in the opposite corner are just for decoration, which means they’re also disabled. In summary, the only working light is the overhead instructor desk lamp.
  • I used two grip strip to mimic a conduit connecting the trainer itself to the instructor’s desk, since two smaller I-beams would have been too long.
  • I put a motor under the instructor's chair to mimic a swivel chair.
    • The J and L buttons spin it.

 

Although I don’t expect much use out of this apart from decoration (and bragging rights for me, since nobody else has made a KSP replica of the Link Trainer), this craft has 2,650 charge units.

  • Jeb Kerman stepping out of the Link Trainer in utter disappointment, talking to his friend, Bill Kerman.
    • When Jeb heard that the first flight simulator - or at least an operational model of it that survived - was coming to the Space Center, he was first in line to try it out. Of course, until then, he didn’t know what it looked like. Although Bill did know what the Link Trainer was, he lined up along with Jeb because he wanted to see it in action up-close and personal.
  • The daughter of the engineer sent to demonstrate how this worked started filming their conversation. Granted, she was filming anyway for her upcoming video "Modern Kerbalnauts Hop On Ancient Flight Simulator." She ended up keeping that part because it was funny.
    • JEB: Why didn’t you warn me that this simulator would suck?
    • BILL: What do you mean?
    • JEB: For starters, it has no computer screen or heads-up display - not even with 4-bit graphics. It also has no sound effects, nav system, or onboard radar. Oh, and I can’t find the music settings.
    • BILL: Obviously none of those things were available when the Link Trainer was made. By the way, why were you looking for the music?
    • JEB: Because the simulators in Basic had those.
    • BILL: They did? Val never said anything about music.
    • JEB: I also can’t find the cockpit light switch. The only source of light I have is from the crummy glow-in-the-dark instrument panel.
    • BILL: It doesn’t have a light switch; the whole point was to get you used to flying in total darkness. By the way, the instrument panel was brighter back in those days, but the original material had to be replaced recently because it was radioactive.
    • JEB: You fly it then if you know so much about it.
  • That was when Bill immediately acted as the "instructor" for the next pilot in line, an unnamed rookie from Nye Island. Surprisingly, he flew it very well on his first try. 
    • When asked how he did it, he replied (with a heavy accent) "The arceed I went to as a lad had a Link Traina. I yesed ta (used to) play on it all the time when the lines to the cool games were too long."
      • And indeed. At the time the pilot in question was a child, Nye Island's local arcade had an operational link trainer used as a game - and it still does.

 

Although the Link Trainer is at the Museum, it's not on the checklist so it doesn't count as a tally; I already have three Hangar One entries anyway. I thought I'd build this replica since nobody else has, so it was a fun challenge. It's still in my museum replica hangar, since I put in a bit of time and effort to make a functional replica - along with the instructor desk.

Achtung! Jetzt wir singen zusammen die Geschichte über den Schweinköpfigen Hund und den lieben Red Baron!

 

qhta6Pg.png

  • Historic photograph from the First Imperial Wars. Here we see the Green Baron, whose real name was (Baron) Manfred von Kermthoven, returning to the recently-built Island Airfield after an air attack on Krakopolis.

 

And here is the story behind this photograph, which is also the story of how the Island Airfield came to be:

Spoiler

The Heinkelian Imperial Navy had captured an island almost 35 kilometers from Krakopolis. However, before they could send the ground troops to the mainland, they needed to establish air superiority over the area. Since their warplanes had such a short range, Emperor Kaiser von Kermhelm authorized the construction of a small airfield on that island for the planes in the upcoming attack. After the landing strip and makeshift hangars were (hastily) completed, Emperor Kermhelm ordered Heinkel’s most feared ace pilot, famously known as the Green Baron, to the new airfield. Emperor Kermhelm, along with several of his military advisors, believed the Green Baron to be the key to Heinkel’s victory in the skies before their victory on the ground.

Sure enough, the Green Baron - along with six wingmen (three of which died) - crippled Krakopolis’ air defense in the first attack. This left room for Heinkelian bombers to take out Allied artillery and flush out infantry units, which were soon blown up and strafed. Allied Command soon realized that the rumors of the Green Baron were true, and they sent telegrams to all their air units to "Watch out for triplanes." As an extra precaution should the Baron make an entrance, they mandated that no less than five fighters at once may launch an attack on any triplane. Though the Baron wasn't the only pilot to use triplanes, his enemies didn't to take the chance that he was the one piloting whatever triplanes they saw.

When the First Imperial Wars ended in a truce, Heinkel was forced to give up all the territory it had gained during the course of the war, effectively shrinking its empire back to pre-war levels. This included the island that they had conquered - and, by extension, their hastily-built airstrip - near Krakopolis. Between the First and Second Imperial Wars, it was used for sightseeing tours. Then, during the course of the Second Imperial Wars, it acted as a naval flight school with at least one cruiser guarding it at all times. Eventually, after the Kerbal Space Center was built, the Island Airfield was abandoned and left to rot.

 

Now back to the present-day test flight.

 

zza9OrY.png

  • The Fokker Dr.I, along with its engine and propeller settings, on display in the SPH.
  • I included "Red Baron’s Triplane" in the craft name in case someone was looking for that plane and didn’t know the model plane he used.
    • Though I suspect it's extremely unlikely anybody who uses KerbalX would know that "Dr." stood for Dreidecker - or that it means "Triplane" in German.
  • Making an open cockpit was tricky. In the end, I decided to borrow the design from ZobrAz’s White Baron - who borrowed the idea from Castille7’s Mrs. Chrissy Too. There’s also a fixed ladder for the pilot to climb in and out, but he would have to click on the command seat and board once he reaches the top.
  • I had to use I-beams connected to the bottom wings to get the top set of wings on.
    • Which are the only ones with ailerons since that was the case for the real-life Fokker triplane.
  • The last test run before this photo was taken had the "Motor Size and Output" setting at 20%. Though it was a success, I dropped it to 10% in hopes of reducing propeller-caused rolling.

 

I’m so used to making even-numbered-engine propeller planes with adjustable-angle R-25 blades, so it was extremely difficult to decide on how to set up a single-engine prop with fixed-angle Type B blades that will not only fly, but spin about its engine axis as little as possible.

  • If the current configuration is giving you trouble, or if you know a way to improve its performance, please tell me.

  • Photograph copied from museum website.

  • (BACK IN PRESENT DAY) Jeb flying low over the KSC in a replica of the Fokker triplane.
    • Not that he had much of a choice. By modern standards, this plane’s performance was terrible.
      • Val assured him that "Back in the First Imperial Wars, any pilot would kill to have a plane with performance stats like that."
      • Bob replied with "And in many cases, they did," earning some laughs from his friends.
  • He was hoping to fly the real thing, but the last real Fokker triplane was destroyed during the Second Imperial Wars.

 

VgSjwzW.png

  • After nearly 12 minutes and 30 seconds of flight and constant course-corrections, Jeb managed to reach the Island Airfield. Just like the Green Baron in the First Imperial War so long ago, Jeb is getting ready to land.

 

The KSP replica's cruise performance stats were as follows:

  • WARNING:
    • Has no autopilot
    • Requires constant attention during flight
    • Prone to axial spinning as propeller runs
  • Altitude: 700 m (2,297 ft)
  • Velocity: 47 m/s (105 mph)
  • Recommended Throttle: 2/3 to Full Throttle
    • For the cruise, it's best to stay at 2/3
  • Expected Range: 90 km
    • DO NOT fly over water when this happens

 

jJdWaU5.png

  • A successful landing at the Island Airfield
  • If you think flying this thing is hard, try landing it in one piece. I had to revert to a quicksave I set up over the island right after my wings snapped off the first time.

 

Man, that was quite a challenge. If I thought making an open cockpit was hard, I was in for a real doozy setting up the prop engine in a configuration that both works and keeps the aesthetic. I don't know how everybody else does it while getting rid of that incessant roll while the engine runs, and I'd like to learn the secret* if possible. For now, I think I'll stay away from odd-numbered-prop engines with fixed-angle blades (at least).

  • Once I do learn the secret, I can make a Sopwith Camel and then Snoopy can pursue the Red Baron. 
    • Unless someone else beats me to it.

If you thought that the first VTOL jet ever built was the British Harrier, you'd be wrong. Although it was technically used as a concept demonstrator and nothing else, that title goes to the Ryan X-13 Vertijet

 

Tg35NZl.png

  • The X-13 Vertijet on display in the SPH.
  • Unlike the other planes on this showcase thread, this one starts out pointed upward. Though subsequent test runs proved vertical takeoff possible, vertical landing in such an orientation was not.
    • At least it can fly, right?
  • The reaction wheel was an attempt to stabilize the plane during a horizontal takeoff, since it kept tilting to the side due to the rear landing gear being so close together.
  • I added Vernor engines in an attempt to make vertical landing easier, but they weren’t much help. In the end, I decided vertical landing wasn’t really worth it - especially since the more famous VTOL jets always did their thing with their noses horizontal.
  • The parachutes were a last-minute addition to make the craft look more like its real-life counterpart, since I noticed in the beginning of this video that the horizontal landing involved a drag chute.

 

151021-F-DW547-006.JPG

  • Contemporary illustration of the Vertijet’s transition from vertical to horizontal flight after takeoff.
  • Image taken from museum website.

 

xePDR4N.png

  • The Vertijet successfully TAKING OFF vertically.
    • That is why the engine is originally set to wet mode, so that the pilot can take off quicker - or at least at all.
  • You can switch to dry mode when you get the Vertijet pointed horizontally.
  • Launch truck not included - not that it’s needed.

 

qG3SivA.png

  • Before the vertical takeoff test could be done, the Vertijet underwent a horizontal takeoff in dry mode. Needless to say that the end result was successful.

 

A TEST CRUISE WAS NOT PERFORMED BECAUSE THIS PARTICULAR AIRCRAFT WAS DESIGNED AS A CONCEPT DEMONSTRATOR AND NOT INTENDED FOR ANYTHING SERIOUS.

 

VNgbVcd.png

  • Horizontal landing was tricky because of the rear landing gear being so close together, but at least each time I managed to get it done without breaking anything.
    • Then again, it could be due to my experience, which means I don’t know how newbies will be able to handle it.
  • Unfortunately, I was unable to orient the Vertijet vertically and fly at a slow enough velocity to land. This craft is definitely VTO, but not L.

 

I'm so glad to have gotten another (mostly) successful replica done, especially after all my attempts at an X-36 ended up with uncontrollable spinning followed by crashing seconds after takeoff. This particular plane looks very "kerbal" with its vertical takeoff - WITH THE NOSE UP.

 

Yesterday, I drove to the museum (for the tenth time) to check out the Operation: Homecoming 50th Anniversary Presentation - which involved the Hanoi Taxi itself. After that was over, I went to the gift shop to buy some jigsaw puzzles for the office where I work, and a 2024 calendar caught my eye. I bought it as a Christmas present - but for whom I have not figured out yet - and noticed something interesting.

  • All the planes featured on it were from the Research and Development Gallery.

 

Here is a list of all the planes featured on that calendar as well as a status report of which of them were replicated on this thread as of today (Sunday, July 16th, 2023):

I wonder which plane's next to be replicated after this one, whether it be made by me or somebody else (preferably someone who knows how to make functional single-engine props).

Ladies and gentlemen, props and jets, straight out of the Strategic Air Command, get your engines hot for the B-36 Peacemaker.

 

Qn9Aibp.png

  • The B-36 Peacemaker on display in the SPH.
  • I started this project by downloading @HB StratosMK3 Custom Cockpit, then adding more fuel cells and modifying some of the fairings to look more like a B-36 cockpit. I then added another small fairing on the top for the dome.
    • If you're reading this, thank you.
  • In order to maintain optimum CoM and CoL balance, I couldn’t fill up all the fuel tanks. At the same time, with each passing test run, I had to be careful deciding which tanks got fuel so I can increase my range.
  • I went with longer blades - as opposed to my favorite R-25 ducted blades - to maintain the aesthetic.
  • During one of the test runs, two of the prop engines froze without explanation. I then installed air intakes on all the engines so that they get adequate air.
  • Thanks to @swjr-swis's advice when talking about my fuel flow problem on my Stratofortress replica a month ago, I enabled crossfeed in the pylons so that the jet engines get fuel from the main tanks.
  • The storage unit in the bottom near the nose is meant to look like a turret.
  • In the end, though the aircraft was able to take off, fly, and land in one piece, I was not pleased with the performance stats. No wonder the B-52 Stratofortress replaced it as a heavy bomber - both in Kerbin and in real life.

 

s10lAFx.png

  • The Peacemaker flying over Alt Test Mountains. Surprisingly, this plane was quite maneuverable for a bomber.
    • But unlike the real-life Peacemaker, I left all ten engines on during cruise.

 

gR7XQh9.png

 

2BLUXSM.png

  • The grabbing unit extending with its claw open during the test flight.
  • I installed a robotic arm with a claw in the bomb bay in case I get ambitious enough to attach an XF-85 Goblin, which was originally designed to take launch from and rejoin the B-36 in real life, to this plane.
  • Then again, since the Goblin project was cancelled due to too many failed redockings with a B-29, odds are I’ll end up making the Goblin replica as a separate aircraft and leave it at that.
    • Controls for the arm are in the KerbalX page.

 

k2UhBmD.png

  • Flying over a mountain range up north in the last test cruise.

 

The KSP replica's cruise performance stats were as follows:

  • Jet Engines: ON
  • Altitude: 6.4 km (~21k ft; Class Alpha airspace)
  • Velocity: 158 m/s (~353 mph)
  • Blade Deployment Angle: 38 degrees
  • Expected Range: 440 km
    • This plane glided for almost 30 km afterwards before touchdown in the latest test flight.
    • The real-life B-36 can fly 10,000 miles (16,093 km).
      • For reference, the circumference of the Earth is approximately 40,075 km.

 

VVWxyCl.png

  • The B-36 landed at a desert with the ladders deployed.
  • Unfortunately, it was impossible for me to reach the command capsule that the crew was in through the fairings. If there were people on board the side capsules, they could have gotten in and out - although I don’t know how that would affect the control scheme since the bomber doesn’t have a probe core.

 

While the B-36 did earn its in the Hangar Three since it served as a nuclear deterrent in the Cold War's early years, had things turned out differently during WWII it probably would have ended up in Hangar One. If you're wondering why, it's because the B-36 was originally thought of as a means to bomb targets in Europe from North America in the event that Great Britain fell to the German Blitzkrieg. Though that ended up not being the case, the U.S. Army Air Corps was uncertain at the time and wanted to be prepared for the worst-case scenario.

  • After WWII ended, America still needed a long-range bomber to destroy targets in Soviet Russia. Though many argued that the (mostly) prop-driven B-36 was obsolete from the start, none of its rivals at the time had the range to attack the Soviet homeland from North America without aerial refueling and couldn’t carry the Mark 16 hydrogen bomb.
  • Until the Boeing B-52 Stratofortress (which is still active) became operational in 1955, the B-36 continued to be America’s primary nuclear weapons delivery vehicle.

 

Next on my hit copy list: the XF-85 Goblin. After that (or if I abort that project for whatever reason), it's a surprise.

In Soviet Russia, you do not fly the MiG-21 "Fishbed."

  • The MiG-21 flies you.

 

9LcGZCg.png

  • The MiG-21 on display in the SPH.
  • I included "Fishbed" in the craft name in case someone was looking for this plane but did not know the model number.
  • For the antenna hanging by the nose (why did the Soviets even put it there), I put a Communotron 16-S on top of a structural pylon, moved it forward as much as I could, then hid the pylon inside the plane. It may decrease flight efficiency due to drag, but considering the test flight results I’d say it’s a near-nonexistent price. Furthermore, the antenna did not explode.
  • I included a battery on the top tanks so that the plane can have a power source in case it needs to glide. Experience shows that you need at least one battery for that or else you’ll lose power before you can switch the engine back on - and then you’re doomed. I originally had a battery in front of the engine, but I removed it to maintain a consistent aesthetic when placing the Soviet star.
  • The cargo bay is empty this time because, well, it’s Soviet Russia. Those communists didn’t care about crew safety (at least not as much as the Americans did). Though the plane is decorated in Soviet stars, the craft’s flag is the classic hammer and sickle.

  • Marxan veteran pilot Ivan Kerman giving a salute before showing off what the Fishbed is capable of.

  • The Fishbed on fire after surpassing Mach 3.
  • This time, Ivan elected to start the demonstration flight north as opposed to west because the engineers estimated he would end up near Marxan territory - which is concentrated around Kerbin’s southern polar ice caps.

 

AqrMB0S.png

  • While flying over Kerbin’s northern ice cap, Ivan got a shot of the Mun and the glow over the horizon. It would be only a couple of minutes before he would enter the dark side of Kerbin.
    • And since this particular plane did not come equipped with GPS, if he was low on fuel he would have difficulty landing. For all he knew, he would have been doomed to splash down or hit a mountain instead of land smoothly.
  • Fortunately, by the time his low fuel indicator started flashing, he was in sight of land. More on that later.
  • Bet there were a lot of kids wishing upon stars that night that ended up wishing upon a flaming jet instead.

 

dKs0gDo.png

  • Less than 45 minutes of flight time, and Ivan's plane is down to its last 50 fuel units. 
  • There’s a nice glow over Kerbin’s southern ice cap; perfect place to land.

 

The KSP replica's cruise performance stats were as follows:

  • Altitude: 19 km (~62k ft, which is Class Echo (E) airspace)
    • WARNING: Tends to bounce up and down in cruise while MJ aircraft autopilot is on.
  • Velocity: 1200 m/s (~2684 mph)
  • Expected Range: 2580 km
    • And it doesn't even come with auxiliary tanks.

 

And this performed way better than its real-life counterpart.

 

bVdIc41.png

  • Ivan performing a soft landing on the ice. Although he was coming in low and slow enough to do so without the parachute’s help, he was ordered to test it anyway. Indeed, it performed well - despite being redundant.
    • Probably because most Marxan pilots spent too much time eating up and spewing out propaganda and not enough actually practicing landing.
    • As for Ivan, he is a veteran ace pilot of the Second Imperial Wars from when he was a young man, so it would make sense that he would (still) know how to land this plane well.

 

3Eg9vzA.png

  • After landing the Fishbed, Ivan realized that he was close to a Marxan outpost. With the sun rise (or set?) close to his location, he stepped outside to admire it.
    • "Command, tell the recovery crews to take their time. I’m home."

 

I know I said that I'd do the XF-85 Goblin next, but during testing I ran into a problem.

 

Just like the real-life Goblin folded its wings so that it could fit in a bomb bay, I added hinges to the wings so that they can fold up and down. However, after I launched the plane, the hinges tended to freeze up while in action. Sometimes it's one hinge, sometimes it's both, other times I get lucky and they're both working properly - until they don't. Even when I revert to SPH and launch again, whether or not the hinges would work has become unpredictable.

 

ga6dZSd.png

  • Cute, but I didn't design this just to give salutes in Air Force parades.
  • For the record, my original plan was to have it launch from a stability enhancer - but each test ended in explosions.

 

I did not mess with the symmetry, so I don't know what's going on. Could someone please tell me what's going on and how to fix it?

  • I asked this question in the KSP1 Gameplay Questions and Tutorials section days ago, but no answer. For more details, check out this post.
    • Also has the craft file if you want to mess around with it and try for yourself.

 

Until I could fix the Goblin, that project's been paused. Which is why I decided to skip to the "surprise" I mentioned would come after the Goblin, which was the Fishbed.

 

Any and all help in solving this problem - or getting some of the more difficult replicas down, for that matter - would be greatly appreciated. Thank you, and do svidaniya.

If you walk by the R&D building at the KSC, you'll notice a semi-lazy entry from the Land of anime girls... I mean pricey but long-lasting cars... Ryanair pilots on crack... surprise harbor parties... the Rising Sun. The rocket-powered Yokosuka MXY-7 Ohka.

 

yY5mnrv.png

  • The Yokosuka MXY-7 Ohka on display in the SPH.
  • It is oriented upright this time so that it could get moving without needing a bomber to drop it.
  • Just like the real-life Ohka, this replica uses a solid-fuel engine. So, once you fire it up, there’s no stopping it.
  • I put I-beams near the front to simulate the landing skis of the trainer model.
  • The solar panels surrounding the command seat are made to look like the cockpit windows.

 

That was when I started getting Pearl Harbor flashbacks - but NOT from Blazing Angels.

  • During spring break in high school, I was with my parents and brother walking through Pearl Harbor. After touring the memorial itself, we headed to the U.S.S. Bowfin Submarine Museum and Park. 
    • For those who don't know, the Bowfin was an American submarine nicknamed the "Pearl Harbor Avenger" that was launched a year after the infamous attack. Indeed, the Bowfin lived up to its nickname by sinking over 30 ships during her wartime service. 
  • One of the outdoor exhibits was a Kaiten, which was a kamikaze torpedo. Although there was an escape hatch for pilots once it got close enough to its target, odds are it was never used. 
    • This caused some more Blazing Angels flashbacks. Not just from the Pearl Harbor attack itself, but on the kamikaze* levels Dad and I used to play.
      • We weren't kamikazes; we were stopping them.
    • The escape hatch was removed in later variants near the end of the war, so there was no chance of getting out (not that suicidal pilots would want to).

 

Seeing this Ohka at the National Museum of the United States Air Force ten years later (as an adult living on my own) reminded me of that torpedo. There is no denying that the Japanese were outright evil during WWII, but one thing you have to admire them for is their people's willingness to die for their country. So much so that they were willing to lock themselves in planes, rocket gliders, or torpedoes loaded with explosives and guide them towards enemy targets.

 

With that childhood memory with a side of WWII history out of the way, here are the KSP test pictures.

 

nodzMN3.png

  • Jeb with his helmet lowered sitting in the cockpit of the Ohka.
  • Just like in real-life, this glider was carried by medium-to-heavy bombers and launched at Allied targets during the Second Imperial Wars.
    • Jeb first thought it rocketed elite commandos further into hostile territory before the bomber could turn around, enemy lines - which obviously meant the pilot would bail out before it crashed. Bob had to explain to him that it was a suicide glider.
      • JEB: "Well, if it was a suicide craft, why bother install skis?"
      • BOB: "The model you're playing in was a trainer."
      • JEB: "That doesn't make sense. Why bother training the pilot if the goal is to crash the plane and kill himself?"
      • VAL: "Says the guy who has an accident liability record as long as a bomber's wingspan."
      • BOB: "The idea was that a suicide pilot would crash into Allied ships and kill hundreds of servicemen. If the pilot missed his target, then you just lost a guy, an expensive rocket, and a ton of explosives for nothing."
      • BILL: "They must have been real desperate if they spent their efforts pulling off a move like that."
      • JEB: "Where would they even find pilots for that anyway? Did they look for suicidal asylum patients? Did they... force prisoners to crash?"
      • VAL: "How would you force someone to kill himself and hundreds of others if the alternative is that he dies?"
      • BILL: "And how can you trust a mental patient to not have a break down and crash prematurely?"
      • JEB: "Either you crash into that ship and blow it up or we shoot your wife and kids. That's how."
      • BOB: "Actually, those suicide pilots were volunteers. Crazy as they were, you can't say they weren't willing to die for their empire."
      • JEB: "That's cold, man."

 

A TEST CRUISE WAS NOT PERFORMED BECAUSE THIS PARTICULAR AIRCRAFT WAS DESIGNED AS A SUICIDE GLIDER THAT WAS DROPPED FROM A BOMBER

 

Wb00uOy.png

  • After the vertical launch and the SRB fuel is depleted, the Ohka is gliding north towards the ocean.
  • A conventional takeoff with wheels didn't yield favorable results, and neither did rocket boosters carrying it up before detachment and firing the main rocket.
    • In the end, I decided to fly it as a glider.
      • And, technically, only a training glider variant (K1) made it to the museum.
  • Without the rocket to send it into a spiral, this glider flew quite well.

 

XyJw8EZ.png

  • A soft landing on the water about 5-7 km away from the KSC, and not a scratch on the glider or the pilot.
  • Jeb volunteered to fly the trainer variant since it was the model designed to keep the pilot alive - or at least not made specifically to kill the occupants.

 

That was a lot of trouble to go through just to copy a suicide glider - and, surprisingly, a Hangar One replica that's pure stock. I still could use some help in fixing the Goblin replica, please. After the wing deployment problem's fixed, I wonder what's next on the list.

If Netflix was looking on this thread for a bomber replica in its latest original show or adaptation, it can start with the B-58 Hustler.

  • The real-life Hustler was actually great and won awards, but it had a smaller range and bomb capacity than the B-52.
  • Though this was America's first supersonic bomber, Soviet high-altitude surface-to-air missiles combined with its own limited range (without aerial refueling) forced it to take on low-penetration roles. Add a high rate of accidental losses, and the Hustler was retired in 1970 after 10 years of service.

 

Ks36tnO.png

  • The B-58 Hustler on display in the SPH.
    • Unlike its real-life counterpart, don’t expect this prototype to win any flight performance awards.
  • Originally, it had four J-404 engines and the fuel tank underneath had fuel inside. While it did provide the supersonic speed I wanted, it came at a cost of an extremely short range and making it near-impossible to land in one piece thanks to the low-hanging engines. That’s when I decided to switch to J-20s; it came closer to the aesthetic anyway.
  • Unlike most of my replicas from the Cold War and before, I installed a probe core specifically for Kerbnet since the real-life Hustler had a …sophisticated inertial guidance navigation and bombing system. (Air Force Museum Webpage)
  • Just like the real-life Hustler, I rigged the cabin to have an ejection mechanism if the ABORT button was pressed.
  • To get this new prototype airborne soon enough, I had to DRAIN THE DROP TANK. That’s why the AC6 button is useless now.

 

If you want to read about how my original prototype test flights went, feel free to expand the spoiler. Otherwise, keep going.

Spoiler

gcZIG7u.png

  • My original replica of the B-58 Hustler, which ultimately got REJECTED.
  • Though it is obviously built for speed, it is not built for range - or, as I would later find out, safe landings.

 

When it came time for the test landings, the engines kept hitting the ground too hard and exploding. After too many failures, I said "That’s it," and installed Juno engines instead. Those were less likely to snap off during landing.

 

Vz8f6Zq.png

  • The Hustler getting a good view of the northern lights while approaching the polar ice caps.
  • Bob did not expect any plane with weak engines like this to go over Alt Test Mountains, so he got the green-light to fly north for this test flight instead.
  • Since Bob’s grandfather was a bomber jet pilot (before specializing in material science), Bob thought it would be nice if he was the one to do the test flight. Of course, Jeb warned him that This plane’s performance stats are lame, which means you’ll have to do a trench run through the mountains.

 

g1BPxed.png

  • Bob flying over Kerbin’s north pole with the moon shining behind him.

 

xx0M0Nh.png

  • Very low on fuel, and Bob’s contemplating whether or not to land before or after going over this mountain range. In the end, he decided to just land early in a green, (relatively) flat spot.
    • At least he managed to cover 1,225 km before being forced to land.

 

The KSP replica's cruise performance stats were as follows:

  • Altitude: 3.3 km (~10.8k ft)
  • Velocity: 150 m/s (~313 mph)
  • Expected Range: 1,225 km

 

cQVPXo7.png

  • A successful landing in a relatively flat part of the the highlands, and with only 10 fuel units left.

 

Like I said earlier, since the real-life Hustler had an escape pod, I launched this prototype again specifically to test it.

 

5HdmU6U.png

  • The ejection capsule was launched and the cabin parachuted down to safety. Too bad you can’t say the same for the nose antenna (but who cares about that).
    • Also why I installed a third parachute on the cabin afterwards.

 

It's a shame that this replica could not come close to its real-life counterpart's performance stats. At least one can look at this plane and say "Yep, it's the B-58 Hustler, all right." Anyway, now that I marked this one off the checklist, I am two funny joints away from checking off the Goblin as well. Maybe if we get enough planes showcased on this thread after that one, the actual museum would notice.*

  • And who knows, they may use Kerbal Space Program (either 1 or 2, but probably 1 if they feature this thread) to teach "The Physics of Flight" or "Design, Build, and Fly Your Own Jet," or something.
