I'm pretty sure @Azimech made a thread on bouancy.

Found it Thanks Its a shame about the claw. I might have to add a mod to the list if I cant make a sub that sinks on its own. I'll have to study Azimechs thread.

Done, Thanks for all the testing Azimech it was very disappointing to see most stuff floats to the point of defying logic.

I also checked the following along with a bunch of comments from Reddit that google turned up;

 

Seems the only way to get a proper sub is with mods, either adjusting the buoyancy levels of individual/or all parts or water density or adding adjustable ballast tank parts.

I might have to make 2 versions of the final craft, one with mods and one without. woth lots of ore tanks on the stock which will look real ugly and be a pain to balance to mention the tonnes of mass to the launch total ( I could fill in LKO I guess ) but damm I was hoping squad had decent or at least realistic values for buoyancy by now.

The US designates a 6th generation fighter as a "all aspect stealth" design, which means no rudders, and no canards, no elevators, and a wing body design with planform alignment as the main form of stealth for the wings, and a buried engine, cooled exhaust, supermaneuverability, payload capability, supercruise of up to mach 1.4 or higher (if it is to be superior to most modern aircraft being developed) and high range.

You lack the following:

-All aspect stealth (although it seems to be at least as stealth, or more so than an F-22, or Su-57.
-Payload capability (no room for medium range, or long range air to air missiles, or any kind of ground ordinance (inside the body for stealth)
-Range, there is no way you can travel across Kerbin with such a small amount of fuel, while carrying payload.

I'd say it's probably one of the better attempts I've seen, Heck, I haven't even made one. It'd be very hard to do in KSP.

Thanks for the input. I've made a bigger version that has 1,5 MKII cargo bays worth of internal payload. I also removed the rudder, burried the engine deeper and made sure all surfaces are angled.

Speed at sea level is worse ("only" 1000 m/s instead of 1600 m/s) and it's a lot bulkier than the previous model (I like small planes), but manoeuvrability is still good.

You're close, but the nosecone is at a different angle than the wings, and the rear of the wings has no planform alignment with the body.

The "hopeless diamond" is one of the only shapes you can make a KSP aircraft stealth with. We can't make smooth shapes.

WIP Von Braun style ferry rocket, keeps burning up on reentry because the heat tolerance on the airliner wings are just plain terrible.

It does fly pretty well though considering how off it looks.

Built a new experimental fighter, and so far I'm happy with it's performance. It can go 300 m/s at low altitude with it's afterburner and 216 m/s without, which isn't bad for a custom-cockpit fighter, and is very maneuverable with a low stall speed (meaning that if you turn too hard and the plane starts to stall it is very easy to recover). It's also one of the prettiest fighters I've built. Now I just have to actually get around to naming and releasing it, which is the hardest step in all of this.

I'm too lazy to make that diamond shape, but I did make a new version of my own design, which should have better stealth characteristics.

Update on the Laythe Aircraft carrier;

Sub testing has now gone through its paces. Fine tuning has evolved into this;

The Mk 3

Able to decend down to a 600 m depth with 1400 Ore which will be placed in the aircraft carrier at launch to enable immediate use once landed on Laythe.

It can store 2025 ore in total meaning it can retrieve 625 ore per dive for the carrier to extend range.

Range for the sub is well poor at least between re-fills, approx 10 km horizontal travel under water, and its slow as well with a max speed of just 12 m/s she wont win any races but will fill the requirement of ocean mining and being able to fit into the Mk3 Cargo bays.

While I hate the fact I needed to clip so many little ore tanks to maintain both fit and look I feel its ok cause the buoyancy in KSP is so off for so many parts that just shouldn't float.

Time for Aircraft

 Space is getting tight and I'm still undecided on what are the aerial requirements. VTOL's its seems are needed as not only does it avoid the plane hitting any snags in the deck but also as thier below deck until landing.

I need to give a shout out to fourfa and the "Smallest, lightest SSTO?" thread in general for helping me make this;

As with most of the craft here it needs a name at the moment its Mini SSTO VTOL Mk3 cargo. Don't know if I really want or need to take the SSTO with the ship I mean it's nice to have one but I think I want more small craft like this little guy,

I can take 3 of them for every SSTO in terms of both space and part count. It's not the best flyer but still fun and easy. But with it I also need to add a way for it to lock into the deck. I've made tiny adaptor things;

 

But I really don't want to need them. so I might need to start again on the plane, I wish we had smaller folding wheels. It did however give me an idea on how to get a rover up on the deck to move planes around. I'll have to search to see if anyone has made a mini rover in a fairing yet. That's assuming that the fairings will protect all these bits from the heat of decent and that they don't change the airflow to badly prior the chutes. That test is still a little way off yet.

I'm building it, the first stock "steam" locomotive. This is a 4-4-2, complete with offset crankshaft (no direct drive on the driving wheels, would make the construction too wide), crossheads and valve gear. When it runs properly I might increase the diameter of the driving wheels to give it a higher top speed. Don't expect blinding performance though, it probably won't be able to run faster than those things from the 1850's.

I once attempted to make something like that out of a static model someone had made on KerbalX. It didn't take long for me to abandon that endeavor though. Good luck making that work!

Speaking of abandoned endeavors, I decided to take a break from racecars and clocks, and work on this neglected thing:

I estimate she's about 50% complete. Cockpit needs some work, most of the tail needs to be built, tail rotor drive and bearings too. Then I need to figure out how to move the center of mass several meters forward (without making it significantly heavier) before I can even think about tinkering with the turbomachinery so it can (hopefully) fly.

Making this thing fly isn't going to be easy. It's gonna be fairly hefty and draggy with all the detailing and whatnot, and the turbine wheel is smaller than what I usually deal with, thus meaning I will get less torque per blower. Torque will be important given the high moment of inertia of the 7-bladed main rotor, something which will probably cause all sorts gyroscopic control problems. When (if) it flies, it will almost certainly have the flight characteristics of a hippopotamus.

Edit: @KandoKris At the top of the text box when you're creating or editing a post, among other things, there should be a symbol that looks like an eye. If you click/tap on it, it will create a spoiler box inside which you can put text and pictures. No need for bbcode.

Improved  Kraftei Nacelles, shortened fuselage, and redid tail plane. Looks more like a 264 now.

[Azimech]

I was one of the pioneers of using light reflection for the creation of custom lighting a few years ago.

This is something new: testing Z-fighting for a pseudo-fire effect in the firebox of my steam locomotive. Obviously a WIP.

 

[Azimech]

Yes, there's a kerbal. 

[Gman_builder]

@Azimech Two question, can your train actually run on a rail? And what is the top speed? I'm interested in how piston engines can actually be used in vehicles.

Looks like it wants to suck my blood. Or one of those silence things from Dr. Who

Impressive work though. Have a gif of it running?

[EpicSpaceTroll139]

Progress on the 53E:

I'd say, ehh... 75% done? I need the tail rotor bearing/power mechanism(s). I'll probably use thermo-rcs bearings for that. Then I need to make the ramp. Currently debating whether to make it movable or not. It would be nice, but the part count is already at 350 or something like that.

Anyways, after those things, I'll try and see if I can get it to fly, and perhaps add pitot tubes, antennas, and other doodads and it'll be finished.

Flown in FAR without reduced drag

Some of you may have seen the new Star Wars fleet project that i'm running right now, and may have seen me say in that post that i might do the super star-destroyer Executor.

Well, i did some number crunching last evening, and using the Recusant class destroyer i made as something to scale it of off, i calculated that the Executor would have to be about 550m long.

 

and here is a tweakscaled "measuring stick" i made to demonstrate that just how big it would be length wise.

Every part was tweakscaled to it's maximum size witch is 400%.

 

Because i want the ship to have a reasonable partcount (i said in the post that a part count of 100 per ship would be a nice goal), and because i want it to be a little more sturdy, i am going to use Procedural Wings for this one.

 

Tough i pretty much know already that reaching a reasonable part count with this one is gonna be almost impossible, i'm still gonna give it a go since it's one of my favorites and because i feel like doing something crazy again.

Wish me luck .

My guess is yes it will ride a rail but it wont be going anywhere at any decent speed. Also, good luck making a rail that goes anywhere with KSP physics in the state they are in..

That's what i was thinking.

Hello all!

I am attempting to re-create the Space-X landing capsule with thrusters and hidden landing legs in Stock KSP, what do you guys think?

Also, does anybody know how to put a Heatshield at the bottom without blocking the landing legs? at the moment if i add a Heatshield it blocks the Landing legs, and then it blows up when i start the thrusters.

[kapteenipirk]

Here's a little update to show you that the SSD Executor is coming along nicely.

 

 

I wanted to give the ship a more proper color scheme by using oretanks as the "super-structure", but it ended up being a pretty part hungry idea, so i desided to just use MK-3 tanks.

 

 

It's 560 m in length and a little over 190 m wide. I really fear that how in the world am i going to get it to stay together .

I'm also wondering that what kind of armament's will i put on the thing (the real one has over 4000 lasers, missile launchers and ion-cannons).

Work on another heavy launch vehicle is almost complete, this time it will be 10kT to orbit.

[EpicSpaceTroll139]

This stuff actually happened last night. I've been pretty busy today with schoolwork.

By uprating the engines, something I often do for replicas*, the main rotor on my CH-53E can now lift itself in the air with its main rotor. I'm having trouble getting the tail rotor spin fast enough to provide adequate antitorque however, and I haven't added any reaction wheels or other attitude control systems, so it just spins out of control and flips out.

 

 

*I do this on my replicas because I make them using stock parts not for the sake of showing what as possible with stock capabilities, but for the sake of them being loadable for players without mods. Thus I strive for the lowest part count for the level of detail I want. I do not use the same philosophy for my non-replica builds, and thus they do not have hacked/uprated parts in their craft files.

Welcome to the forums! I suggest moving the thruster out and up, and hiding the top with another part. The link above shows someone who made one in stock, though it was a long time ago. Not sure how to do the heat shields, but I look forward to seeing to the finished version!
