  1. The K-Prize Party Thread. K-Prize badge by WafflesToo (sig badges). The K Prize challenge is to make the obvious craft, a spaceplane, and make it work. All those who succeed will be included on the roll of honour and get a free back stage pass to hang with Kay Kool and the Kerbettes after their next live performance at the Dog and Booster (where free beer will be available). To enter report relevant accomplishments on a mission which actually flew, your word is good enough but images and videos are welcome. Rules 1. The craft must launch and land intact using only the amount of fuel on board at launch, may not lose stages or parts in flight, no refuelling for thrust, see provisos below. 2. The craft must launch horizontally, reach orbit (PE > 70,000m) and land intact (on Kerbin) ready for 'refuelling'. 3. All fuel tanks, wings (ie lift generators & aerodynamic environments) and engine parts must be stock, for fairness. Provisos to rule 1. A. Payloads may decouple from the craft providing all payload tanks are as full on decoupling as at launch and any thrust (or lift) generators on the payload were not used prior to decoupling. Excursion vehicles may decouple and redock but only achievements of the entire craft count towards K-Prize kudos. B. Docking is permitted providing no fuel is transferred (net per fuel type) into the K-Prize craft and then used for propulsion (it can be transferred out or in as payload). Likewise no propulsion assist is permitted from the target craft fuel or engines. Crew transfers are permitted. C. Mining and refining are permitted providing none of the resulting fuel product is used to drive the craft i.e. mined fuel is treated as payload only. D. Pilots wishing to try the challenge with mod equipment may do so in the sister challenge thread "The K Prize - 100% reusable spaceplane to orbit and back (Modded Version)". +Kudos 1. Smallest ship (by weight, weight info required). Minimalist record. 2. Largest ship (by weight, weight info required). Maximalist record. 3. Highest orbit beyond Eeloo. Altitudinalist record. 4. Landing on any space center terrain. Pilot proficiency medal. 5. Landing on any space center runway or docking in orbit. Advanced pilot precision award (1stClass for both). 6. Visiting other SOIs. Kosmokerbal Commendation. 7. Planetoid landings. Astrokerbal Distinction. 8. Payload to orbit, including fuel delivery also ore, fuel or salvage to Kerbin from asteroid or orbit. Utilitarial Commendation. 9. Payload to distant planet surface including fuel delivery also ore, fuel or salvage to Kerbin from planet. Utilitarial Distinction. Prefixes: Exploratory applies to planetoid missions and Expeditionary applies to planetary lander missions outside Kerbin's sphere of influence. (Planets are defined as the central body in their own SOI with a boundary adjacent to Kerbol's SOI or gravity exceeding 0.75 of Kerbins.) Guest List (Roll of Honour.)

Version 1.1 + Version 1.0.5 Guest Lists from previous versions. Gate Crashers (Dodged the bouncers.) K-Prize Gatecrasher's badge by WafflesToo (sig badges). Hall of infamy. Previous gatecrashers. Temstar insisted that upstaging Elon Musk was not against the K-Prize rules. Kokanee declared the runway to be disruptive technology. ihtoit quoted in kerbin Gazette "trial and error isn't so expensive if you leave insurance claims until after the next launch". Gojira1000 didn't mention the drilling equipment and fuel converter to the K-Prize adjudication panel since it was a minor detail. manni01 was adamant that refueling was essential for returning to Kerbin, supplied video evidence. Didnt read proviso C because it was "just the small print". micr0wave forgot which side the wheels were on, may have lost a wing... or two. JebsDead said whatever exploded wasn't very important... probably. (Presented a couple of mining videos to show how rarely explosions matter.) n.b.z. wasnt sure how to get Mirgy and her flying saucer back from Duna but was OK with that. Spartwo beat the odds but lost quite a lot of spaceship. cy4n argued that a spaceplane was a rocket with wings, suggested the K-Prize panel should try not to worry about the "drop tanks". luizopiloto considered the mission a democratic success, since a majority of parts didnt explode on touchdown. Jebediah Klerman brought a rocket to a spaceplane challenge. Felt rules were biased against vertical take off, which they are. Spaceception came back down to Kerbin with a bit of a bump... and an explosion... or two... Marschig glossed over refining-refuelling at Laythe, denied being a rulebreaker saying, "the rules were like that when I found them". hoioh suggested there was no such thing as bad publicity. HyperDraco confirmed that extensive research had shown its best to put wheels on the outside. Rhomphaia retorted to a Kerbopolis Times reporter that detachable engines were all part of the plan, or at least half of them were. xendelaar announced on YouKube the Honey bee had broken the mold for conventional helirocketry. Replied to comments that reading the K-Prize rules was on the to do list. camacju when asked why crash the K-Prize party with perfectly good tickets replied, "because it was there". tosha told reporters that hacking the KASA mainframe was only to assist a refuelling maneuver, was very sorry it broke a rule but felt its easier to ask forgiveness than to get permission. Admiral Fluffy switched off altimeter to get better publicity shots, told This Week In Rocketry podcast "sometimes less is more". 4D4850 accidentally parachuted into the goat paddock of the petting zoo next to The Dog & Booster. Told police "I would've gotten away with it too, if it weren't for those meddling kids." OJT took upstaging to a whole new level. Announced on Kerbal Radio, the Pyramid at Klastonbury was eclipsed by the Cuboid at KSC ... about 16 times a day now it was in orbit. - Was flying high until pilot Jebediah Kerman fell off the map, entered the twilight zone and was eaten by a cyber dragon. We salute your sacrifice but no admittance without a bonafide ticket. ... can you do better
  2. OPT Reconfig Supplies highly needed config files to keep OPT Spaceplane Parts | Continued useful and alive in the absence of the original modder, @K.Yeon and in the changing KSP gameplay landscape. It is an optional enhancement to OPT's "Main" package (V2.0.1) and it does nothing by itself. It is required by OPT Legacy and by OPT Spaceplane Continued. Do not use this: With my old modlets OPT_USI or OPT_WBI. They are now features of this mod. With OPT Legacy v1.0.9 or lower. If you have an OPT FAR config already. If you have one of these, delete it. This mod also contains an OPT FAR config. Both will run and will cause serious problems. Required by OPT Legacy 1.1.0 or higher, and OPT Spaceplane Continued. Required mods for this: B9 Part Switch + ModuleManager just to work. Community Resource Pack or WBT (Wild Blue Tools) bundled with any of Angel-125's mods, for tank options. Required mods for IVA: ASET Prop Pack by @alexustas ASET Avionics by @alexustas For KSP 1.8 and newer: RasterPropMonitor (Adopted), by @JonnyOThan For KSP 1.7.3 & earlier: RasterPropMonitor by @MOARdV Supported Mods: Connected Living Space, by @Papa_Joe FAR (Ferram Aerospace Research Continued) by @dkavolis Kerbalism by @Sir Mortimer OPT "Main" by @K.Yeon RemoteTech by @tomek.piotrowski Snacks! - Friendly, Simplified Life Support by @Angel-125 TAC Life Support by @JPLRepo USI Life Support by @RoverDude Recommend Extras: The WBI Suite of Mods [GitHub] by Angel-125 Textures Unlimited: Recolour Depot by @Manwith Noname (Does not support OPT Legacy) Craft Manager by @katateochi Craft Manager replaces the stock caft loading UI with something bigger, more beautiful and very feature rich. It also integrates KSP with an external craft sharing website, KerbalX.com, (also created by Katateochi), where you can download or share pre-made craft files that use OPT. Over 5% of the ~16,000 craft files hosted there use OPT parts. Feel free to show off your own OPT craft, or view others' works in the OPT Showroom thread. What OPT Reconfig does: Adds a higher tech tree node than Experimental Aircraft Engines for the most OP of engines. Makes all main pack engines less OP or keeps them OPbut makes them rightfully more challenging to use. Makes the weaker engines stronger at reasonable cost. Makes these exact changes to OPT Main's engines: Buffs the Isp and doubles the thrust of J Aerospike, and gives it decent gimbal. Makes the ARI-75 engine require EC to justify its higher vacuum Isp and gives it an instant-response second mode for vacuum lander-friendly use. Makes the J-92 Shcramjet into dual-mode with the second mode as a proper EC-guzzling future scramjet that starts at Mach 4 and is useful in upscaled systems. Makes the Dark Drive regenerate and require Dark Goo (as implied in its part description) and also serve as an RTG with half-life, and gives it 1 deg of gimbal. Related: equips the J science lab with a facility to produce Dark Science required to regenerate Dark Goo, and gives the stock Experiment Storage Unit some Dark Science tankage to avoid all Dark Drive equipped craft needing to have a J science lab. Makes the HAE-02 Mk2 engine less thrusty. Replaces dirty old Firespitter configs with B9 Part Switch and Wild Blue Tools (WBT) which make it much easier to add the tank types you want to all parts in OPT Main and Legacy). Provides additional tank types if the following mods are found: CryoTanks, Near Future Propulsion. Integrates USI, TAC or Snacks! (life support) through B9 Part Switch or Wild Blue Tools. Integrates Kerbalism through its own mechanisms for crewed parts and B9 Part Switch for all other parts. Delivers the OPT FAR config.

  3. Like the stock Mk2 parts, but are round instead of streamlined. A lot of the time the stock Mk2 parts don’t really have enough capacity in the cargo bays or fit the aesthetic that I’m going for. They could also open up new opportunities for aircraft recreations. And for people who say that I could just use Mk3 parts, a lot of the time they are just way to big, hard to work with and difficult to get off the ground. These Mk2 parts IMO would make a nice alternative for when you don’t want to engineer a giant shuttle but still need some space. To make sure that they aren’t overpowered they would be heavier and less aerodynamic that the stock Mk2 parts. What do you think?
  4.

  5. BASIC MK2 WHIPLASH/NERV SPACEPLANE TUTORIAL The best looking airplane parts in the game almost certainly belong to the mk2 family. The part descriptions combined with their "hypersonic" appearance make them a natural choice for a new player, unfortunately they generate more forum help threads than anything else. Pic - the wrong stuff ! Problem 1 - Poor Performance Mk2 parts generate at least twice as much drag as a mk1 or mk3 fuselage built to carry the same amount of fuel or passengers. As a result they are frequently unable to break the sound barrier. If the player tries to overcome this by spamming engines, they often run out of fuel before making orbit. Problem 2 - Flipping Out The aerodynamic forces generated by draggy fuselages are not properly taken into account by the stock game's Centre of Lift indicator, resulting in a CoL much further forward than it actually appears. Second, new players usually try to build something that looks like a sleek real-world airplane, with a cluster of engines at the back and a long, pointy fuselage up front. On launch, all that fuel at the front of the ship balances the heavy engines at the back. But when the tanks empty, CoM shifts far to the rear and the plane becomes unstable. Problem 3 - Exploded Cockpit In recent versions of KSP aerodynamic heating effects are much stronger at the front of a stack than they are further back. As a result, despite its much higher heat tolerance a pointy mk2 cockpit is much more prone to overheating than a mk1 inline one with a few parts in front of it. Mk2 Tips - the short version To minimise the drag penalty, keep the mk2 fuselage as short as possible. Use it for Kerbals, cargo and other mission stuff, but avoid storing fuel in mk2 parts except for when you're fitting a mk2 bicoupler or mk2 to mk1 adapter anyway. If your ship has NERV engines, fit as much wing as possible but use only fuel containing big-s wings and strakes. You can in fact store all your liquid fuel this way. More wings allows the craft to fly higher and at a lower angle of attack for any given airspeed, which reduces the amount of drag (and heating) on your fuselage. Use an inline mk2 cockpit Combating the dreaded rearward CG shift as fuel burns off This problem is such a (night)mare, I'm going to have to give its own list For your first mk2s, stick to crew ferries or combi ships. Passenger cabins and inline clamp-o-trons give you a bit of mass you can put up front to balance those heavy engines. Try to shift engines forward if possible, especially the heavy ones. For example, consider putting the heavy nukes on the wings or on pods either side of the main fuselage, whilst the lighter jet engine(s) can go on the attach nodes on the back of the main fuselage. Try to move your fuel stowage rearward. Given the problem of instability, why am i telling people to move anything backward ? Well, if you've succeeded in balancing the weight of those heavy engines when empty, your next problem is that you've probably got more fuel tankage ahead of CG than behind it. When you fill the tanks, your craft becomes excessively nose-heavy. This is more likely to be an issue if your craft has a CoM well to the rear - sure, you can move the CoL aft as well to make it stable, but this places most of the fuel tanks ahead of CG. When you fill all the tanks it becomes a lawn dart. So, you need to find ways of increasing the fuel tankage at the back of the ship. Consider putting batteries, reaction wheels and engine pre-coolers at the front of your size 1 stacks and only have fuel tanks immediately in front of the engine. Big S wing strakes, orientated vertictically, can be used to build tail fins and they have a surprising amount of fuel capacity. Also, you may be able to attach big S strakes to the trailing edge of the wing. Big S strakes hold more fuel for their size than the main wing, so help to shift the fuel balance rearward. Pic - our original failplane, better balanced (but still melty and draggy) Some mods that will make your life much, much easier RCS build aid Shows a red dot in the SPH/VAB which indicates where your CoM will move to when the tanks are empty. Makes it much , much easier to build planes that don't flip out on re-entry. CorrectCoL CorrectCoL does two things. Firstly, it makes the blue CoL indicator in the SPH more accurate by taking into account aero forces acting on fuselage parts. Second, it shows a stability graph for your airplane across the AoA range. When the line is above the horizontal axis, it indicates your plane wants to nose up. When it is below, it tries to nose down. You want the line to slope downhill left to right, so that the greater the AoA , the stronger the nose down tendency. The point where the line crosses the x axis indicates the pitch attitude the plane will tend to adopt without any control input from the pilot. A Quick Word on Part Attachment and Drag It is worth remembering that KSP craft files are organised as a tree structure. There is a root part, to which any number of items can be attached radially, as well an end attachment node to which subsequent parts can be attached, and so on. To the game, a typical mk2 spaceplane, with an engine on the back and a mk1 sized engine nacelle attached either side of the fuselage, is just like a rocket with a pair of boosters attached radially to the main stack. In this case we have the main stack (the mk2 fuselage) and the engine nacelles which are like boosters. (I've numbered the parts in terms of how far away they are from the root in the craft file) Rule 1 : Every end-attached stack of parts must begin and end with something pointy. "Pointy" means something which has an attachment node at one end, which joins it to the stack, but not at the other. Obviously, it also means something low drag. Parts in this category include in order of more to less streamlined ⦁ nose cones and fairings (Duh !) ⦁ jet engines ⦁ rocket engines (more drag than jets, due to the attach node on the back, but has been reduced in the last patch) ⦁ air intakes (somewhat draggy, inline intakes like the engine pre-cooler are better if you're min-maxing efficiency) ⦁ shielded docking port (quite a high drag part, you are better off with an inline clamp o tron if you must dock) Rule 2 : When joining parts together with end-attachment, the diameter of the attach nodes of the parts being joined MUST match. Just because the game lets you join a 0.625m small nose cone to the front of a 1.25m fuel tank, or lets you put a Poodle on the back of a mk2 fuselage, doesn't mean you should. These mismatches create huge drag. If you need to attach a 0.625m part to a mk1 stack, use a low drag adapter like the FL-A10 or the NCS adapter between them. If you want a Poodle (2.5m rocket) on the back of your mk2 spaceplane, use a mk2 to 2.5m adapter. One last thing. When attaching stuff, be aware of orientation. End attached parts like fuel tanks, intakes, nose cones, engines etc. have lowest drag when aimed directly prograde or retrograde. Angling parts a few degrees away from pro or retro increases drag. Just how bad are mk2 parts for drag ? A screenshot is worth a thousand words. You can see that the mk2 inline cockpit has over 3 times the drag of the big S wing. The short mk2 cargo bay has a little bit less, since it doesn't have the sticking up bit at the top with the windows. It's not in this picture, but the mk2 to 1.25m short adapter has about half the drag value of the short cargo bay. And you can see that the 1.25m nuke rocket engine was very little drag at all, by comparison. note - you can bring up this data any time you want by pressing ALT F12, going to the physics menu, and clicking on the Aero tab. The big dialog box with that welter of aerodynamic data is enabled by checking the "display aero data GUI" option. The drag info in the right click menus comes up when you check "enable aero data in action menus" part 2 to follow (examples of common part attachment problems)
  6. About This is the new thread for B9 Aerospace. The old thread is available here This pack adds a vast selection of new parts, introducing new spaceplane components such as new engines, cockpits, wings and fuselage systems, new structural components for orbital installations and colonies, and so on B9 was originally developed by @bac9, @Taverius, and @K3-Chris, now maintained by @blowfish and @Flashblade with help from many others Requirements The latest version is compatible with KSP 1.8.x. The bundled dependencies are for KSP 1.8.1 and may not work on other versions. All other KSP versions should be considered incompatible. If you are on an earlier version of KSP, however, you may be able to find a compatible version of B9 here B9 depends on several other mods to make it work. They are included in the download, and listed below in the "Dependencies" section. Installation Instructions You can install with CKAN and have the dependencies installed automatically. If you are doing a manual install, open the zip you downloaded, find the GameData folder and copy all of its contents into your existing GameData folder in KSP. If you already have any of the bundled mods, check which one is the latest version. Note that the core and HX packs come with the same version of some dependencies. B9 will not work unless installed correctly. If you're having issues, please verify that you have installed it correctly. Download Three packs are available for download: B9 Aerospace Core Pack - All of the main spaceplane parts B9 Aerospace Legacy Pack - Older Mk1 and Mk2 parts, modular wings. Requires the core pack and all of its dependencies B9 Aerospace HX Pack - Large blocky futuristic parts. Does not require the core pack, comes with its own dependencies Download mirror: S3 Also available on CKAN Changelog FAQ Q: The mod crashes the game for some reason, what can I do? Make sure that everything is installed correctly, your dependencies are up-to-date, and you are on the correct version of KSP. If you can't find the issue read this helpful topic and post the issue in this thread. Be sure to include your logs! If you are quite certain that you have found a bug, you can create the issue on our Github page. Try to provide as much detail as possible - logs, example craft, reproduction steps. Also be sure that the issue is reproducable with only B9 installed. Posts along the lines of "Its not working" or "Everything is broken" won't really help us much. Q: I don't understand a thing in those IVA displays, there are too many buttons and screens Here is a very helpful manual. Q: Why aren't you respecting stock balance? Mods should reference stock for the configs of the new parts, otherwise balance of modded game would be all over the place! While we try to respect stock balance as much as possible, there are a number of inconsistencies in the balance of stock parts that make it impossible to keep balance against every stock part. If something seem very far off of what it should be, feel free to ask in this thread. Q: I can't find those huge blocky parts from the opening image in my part catalog. Why are those missing? They were recently separated into another download as they mostly don't share dependencies with the main part of the mod and as many people prefer not to use them. Q: I can't find the modular wing pieces that are depicted on many screenshots of this mod. Why are those missing? They were removed and will no longer be developed. They are available as an optional download in the Bitbucket repository linked on top of this post, but we do not recommend using them. A far better option is using procedural wings, since you'll have just one part with just one material and just one texture covering any possible wing shape then. Good for performance, good for design freedom, good for looks. Grab the procedural wings here. Q: Why aren't procedural wings integrated into the main B9 package? Because they have entirely separate dependencies and are maintained by different folks. Merging them will only needlessly complicate updates.

  7. Yes. Today i made a spaceplane that looked very fine to me. One flaw it had was due to the annoying kraken made it spin sideways. Even using RCS or even SAS doesn't fix the sideway-spinning kraken. Even restarting multiple times doesn't fix the annoying kraken. edit: I realized it was that tiny little annoying dragging @ssh0le basically why does even atmospheric drags exist?

  9. So I made a TSTO tourist spaceplane that works really well, but up until this point, I have been landing it in random fields because I always miss a runway, but I finally managed to get this thing to the dessert (that wasn't a typo) airfield! You will not believe how excited I was when I realized I could make it. This is a screenshot I took after landing (yes it is conventional geared, it was more stable than tricycle gear believe it or not)

  11. I present to you fine spaceplane enthusiasts... the Kerbal Wind Tunnel mod! We all build spaceplanes to fly faster and higher, but how do you know how fast or how high your current design can go? In the real world of aircraft design, engineers calculate the flight envelope for their aircraft before the first test flight rolls out. This mod runs your spaceplane through a virtual wind tunnel while still in the SPH and predicts its engine and flight performance at every speed and altitude. It also gives you a readout of various performance curves, plotting against angle of attack: ... and velocity: Try it out and start building even better spaceplanes today! You can even output the data to a CSV file to incorporate knowledge of the performance data into a KOS script or the like! Check out this Imgur album for more details on these images and more: https://imgur.com/a/D2i4Fge Download it from GitHub: https://github.com/DBooots/KerbalWindTunnel/releases Or SpaceDock: https://spacedock.info/mod/1927/Kerbal Wind Tunnel Source: https://github.com/DBooots/KerbalWindTunnel Released under the MIT License (with sub-components under their own license). P.S. This mod incorporates a pretty sweet graph-drawing library I made. If anyone's interested in super-simple graphing of data, hit me up.
  12. So there I was, sitting and having a bad day. How do I build a Spaceplane!? I can't build SSTOs, Those are too hard. I can't put it on top of a rocket, because it just flips...or can I? I wonder... (some weird engineering later...) And this is the result. I took a rocket, flipped it on it's side and strapped wings, wheels and jets to it. Here it is sitting on the pad-Wait, this isn't a launch pad. 147 Parts, 61.021 Tons, 4.3 Meters tall,, 12 Meters wide, and 25.5 Meters long. 2 Panther Engines on each side using Wet Mode provide power for the early ascent. Main Engine is a Skipper. Second Stage is powered by a Cheetah Engine, and the Spaceplane itself is powered by 4 Sparks, 2 below each wing. You can't see them now, but you'll notice later. The Spaceplane has taken flight! Ascending to the skies above...Soon we'll be above the skies! Jet Engines are starting to lose power, so the main engine fires to keep us accelerating! The Jet Engines are no longer effective, So they are jettisoned. A few seconds after seperation. The Second Stage activates as Stage 1 falls away. Maybe someday I'll be able to reuse it... Second Stage is at full power. Second Stage is seperated and Spaceplane is almost in orbit. Orbit Achieved! And there's the payload, a probe bound for...uhh...I never picked a destination. Is there anything I can improve on? This is my first actually useful Spaceplane and I'd like to build more like these!

  14. Hello once again! Today I bring you, My latest attempt at an interplanetary VTOL SSTO. When launched fully fueled, it can reach LKO with ~2,200 m/s of delta-V remaining. From there, it can be flown non-stop to Laythe and back, using ISRU to refuel on Laythe's surface. The design is oxidizer-free, and the fuel tank layout preserves the C.O.M. position regardless of fuel levels. The engine layout includes two forward-fixed Nervas, four R.A.P.I.E.R. engines (two forward-fixed and two pivotable), and two pivotable Panther engines. When flying in VTOL mode, it's easiest to set the throttle to allow for a TWR<1 while the Panthers are running dry, and a TWR>1 while running wet. This will allow some fine throttle control by switching the afterburners on and off during landing. When flying to orbit: 1) Once off the ground (via either VTOL or STOL to save some fuel), set the pivotable engines forward (AG1) with the Panther afterburners off (AG2). 2) Activate the fixed R.A.P.I.E.R. engines (AG4). 3) Cruise up to ~10 km before turning on the Nervas (AG5). While this is normally a tad too low to be using Nervas, the ISP should already be 700+ and we'll need as much thrust as we can manage. 4) Once all jet engines flame out, shut them down (AG3 + AG4) and continue to push to orbit on the Nervas. The TWR will be fairly low once you're running on the Nervas alone, so pitch up slightly to keep your time to AP around a minute. Eventually, when your orbital velocity reaches ~2,300 m/s you'll be safe to cruise to AP and circularize. Action Groups: AG1: Toggle VTOL engine pivots AG2: Toggle Panther afterburners AG3: Toggle VTOL engines AG4: Toggle fixed R.A.P.I.E.R.engines AG5: Toggle Nervas Gallery: I really hope y'all liked it, and if you want to try your hand at flying it, you can download the craft here: https://kerbalx.com/Jamie_Logan/Fenghuang-H-77 Also, check out my last build!
  15. Hola colegas bueno estoy teniendo un problema serio y es que mis aeronaves terrestres son totalmente incontrolables no se si es por la ultima versión que ha salido o si le cambiaron algo de la física del juego, les cuento. Tengo en mi modo carrera 5 aviones que en las versiones anteriores volaban con algo de dificultad al despegar pero al menos volaban y hasta algunas las podía hacer aterrizar, ahora mis aviones ni siquiera pueden despegar pues siempre se van hacia la izquierda y el avión termina volcando como si fuera un camión que se sale de la ruta. Me dije bueno tal vez no les hice un test bien entonces voy y me hago 4 aviones de cero, si totalmente de cero pero el resultado es peor que el anterior. Entonces la gran pregunta es. Soy yo o tocaron algo del juego que hace que pase esto es un bug o que? Si a alguien mas le pasa esto que comente. Si alquién quiere testear mis aviones me avisa y le dejo el save para que pueda comprobar lo que estoy comentando.
  16. KerbalX link: https://kerbalx.com/OlMuskiBoi/Stock-Dreamchaser Not perfect but I'm happy with how it turned out. Launch vehicle isn't anything special, feel free to throw it out for a proper Atlas / Vulcan replica if you want
  17. Here's the story. I decided to build an SSTO that can carry a three-person spaceplane into LKO and leave it before landing at the KSC. That way, the spaceplane itself will be ready for its interplanetary burn with all its liquid fuel tanks full and I won't have to drop any debris on the surface. For an aerodynamic design concept, I viewed Matt Lowne's air-launched spaceplane video. Though I followed the video while building my plane, I made sure to add my own parts in my version (e.g. rapiers instead of airliner engines, reaction wheels, NERVs, more oxidizer for the rapiers, etc). I plan to get BOTH craft in orbit instead of sacrificing one for the other. Below is the image of my prototype (spaceplane included). I do not plan to change the spaceplane, so it's the carrier I need help on. STAGING SEQUENCE: 5: Carrier rapiers 4: Carrier NERVs 3: Detach spaceplane from carrier Attached via docking port 2: Spaceplane NERVs Should be separate from carrier by then. 1: Spaceplane rapiers 0: Spaceplane rear parachutes Spaceplane has ~4,952 m/s of delta-V with its oxidizer tanks (99%) depleted, so there's the reason why I want this to work so badly. Craft file: https://mega.nz/#!iSglSAKT!iyaMk3pM_rt1HMWtCXu4ROxektOhf-tsHE4Y5OqtBig While the appeal of this design seems awesome, the test results are anything but. For instance: My aircraft keeps sliding on the runway, even at maximum friction control. I can't achieve LKO. I did once, but I could not repeat it. More details on what happened later. Honestly, I forgot if it was this prototype or another one. Either way, I was lucky. The other times, I failed to achieve an apoapsis above 70 km before I got below 39 km (or whatever altitude you can't bounce back up from). When I did reach Ap=70 km, I couldn't get my periapsis up in time to avoid getting recaptured in the atmosphere. (IN THE ONE TEST RUN THAT I ACHIEVED LKO IN) My carrier plane lost control after re-entry, and I spun uncontrollably in the air. In fact, my tailfins snapped right off. I had a bit of trouble keeping this plane straight when the carrier's rapiers activated. More specifically, it wanted to pitch way up for a bit until its oxidizer supply was depleted. I then tried Matt's Stratolauncher design concept, but that prototype turned out even worse. When the rapiers switched to rocket mode, I rapidly pitched downward. The picture below shows the prototype in question. If I had to guess why, it's because of the three rapiers on the top being so close together What should I do for my carrier to work? What kind of design is necessary to function both with and without the spaceplane? Any and all help is greatly appreciated. If you want to try it out for yourself, feel free to ask for the craft file (aside from the one I posted here) One more time: the spaceplane shall not do anything until it is released from the carrier in stable LKO.
  18. Hi All! I've been trying a little more with SSTO spaceplanes recently. I've done some in the past, mostly small ones with stock parts, but in this heavily modded career game I wanted to try big, so I built this one using moslty OPT parts, which I wanted to use for a space camp mission (bring 15 tourists to orbit). It actually has a pretty decent TWR, not a lot of DeltaV probably, but I haven't tuned it yet...mostly because I can't get it past 370 m/s or so. In the picture attached you can even see that I'm pitching down, but even pitching down, my speed was DECREASING... So. I'm showing the aero overlay, by doing some googling, I saw people seem to suggest drag from clipping parts might be a thing. I can't honestly think of anything else, given the large wingspan and high TWR. Is drag what I'm looking at? If so, how do I fix it? Thanks in advance!
  19. Hello guys I didn't found any topics on Spaceplane in RSS mode, so I create this one I am playing RSS (Real solar system) on KSP 1.7.3, but not R . It is yet a big challenge to send a rocket or a spaceplane in orbit as you have to reach Mach 25 or more than 7500m/s to be free from gravity. Stock engines stock are not an option to send a rocket or a spaceplane in orbit and I use Real Scale booster engines and OPT mod engines. SSTO is impossible. What I decided is to create a Stratolauncher, then have a spaceplane on the top to launch it at the Stratolauncher ceiling at the quickest speed to achieve orbit. For planes OPT engines are very powerful and we can reach 48kms as ceiling. Then launching speed depends on the StratolauncherTWR and 5000m/s are reachable . To achieve orbit climb you can't rely on gravity turn, and you must use the PrimerVector method that Mechjeb is using in RSS/RO which is to adapt your speed vector to be as near as possible from your apogee (less than 15s is great) to achieve your orbit in only one burn......That allows to save a lot of DV. Atmospheric autopilot mod is a good mod to fine tune your speed vector while piloting your spaceplane to orbit. My first spaceplane is designed to reach the moon orbit. I built a ascent and a descent stage behind the cockpit to make this stuff detachable from the spaceplane core. So, the cockpit will land on the moon, then leaving the descent stage on the moon, it will climb back to orbit and dock to the spaceplane core. The shorter spaceplane will fly back to earth Meanwhile, using FMRS, the Stratolauncher will land to base. The base is Kourou. Here is my trip to Moon in RSS with The Stratolauncher, renamed StratoRaptor and the Spaceplane Raptor whose cockpit will undock and descent on the moon. We need to reach 25, around 7500m/s to leave Earth, which is impossible with an SSTO, even with OPT engines That's why I create the Startoraptor launching the Raptor Spaceplane. Weight of the raptor in charge is around 153T The 4 hybrid engines of the Raptor leaves 13000DV range in vacuum provided you give them 50 electric units/s during engines run The cockpit with its descent and climbing stages decoupling from the Raptor core are the Moon lander. Here is the service bay with 20 NearFututreElectrical RTGs to help the Hybrid engines in close cycle mod Here is the Stratoraptor 995T bicockpit plane with 80% fuel. 12 OPT J61 engines giving a TWR >3 at the engine ceiling around 48500m. That allows More than Mach 15 at launch Take off and heading 117° to be on lunar plan Climbing 70°, acceleration around 15000m and mach 2.5 Leaving 37000m under acceleration, we try to stay a near as possible from apogee: see the MechJeb PrimerVector concept in RSS/RO in the RSS RO wiki (very interesting) 43500m; Mach 13.5 less than 5s from apogee, great acceleration, we should launch at more than M 15 Launch at more than mach 15 StratoRaptor being in sub orbital flight with engines shut that 's an awesome optimal climb for the Raptor reaching 5000m/s a 52000m Approaching orbit with more than 10000DV Lunar transfert calculation Meanwhile with FMRS,we come back to the StratoRaptor which is 1200kms far from base. The best return flight to spare fuel is the following: vertical dive engines shut, then engines relight under 30000m, inverse Immelmann to climb to orbit we begin climb on the back around 13000m Then half barrel roll and climb to suborbital A second suborbital climb is necessary to avoid fuel shortage the shortest possible approach we try the runway which is very hard with such a big aircraft. Use of Atmospheric autopilot is a great help On the ground Here in lunar orbit, undocking the lander Lander retrobreaking Gear down fine landing Crew goes out to plan a flag Climbing back to cockpit for departure The descent stage stays on the Moon climbing to a 45kms orbit Back view from tanks and climb engines Calculation of docking point approach and angular alignment on the fuselage Cockpit docked and well aligned, Raptor is now shorter as we left the descent stage on the moon 7000 DV left for earth return 2mn HD vid for cockpit separation and landing https://youtu.be/Oub2VP7PagM 2mn HD vid Cockpit docking after moon climb https://youtu.be/K45A36cMzak 815 DV for earth injection Then 1800 Dv to get 8000kms apogee with 160 perigee Then still 1500Dv to circularize at 160kms break enough for re entry South burn aligng with the launch base, it's 1300 DV more due to overheat speed brakes are destroyed lighting engines in air breathing mode long final on Kourou runway Kourou which is an island like all other bases in RSS (I think it's a bug from the mod which is not updated for KSP 1.7) Landing fascing East, too long, pull up and landing facing west long landing and stop at the very end of the runway Conclusion I am happy with Stratolauncher to launch spaceplane. It works very well with OPT engines. Maybe it could be a good idea to gat a back inflatable shield on the spaceplane to spare aerobraking fuel I am planing a bigger Stratolauncher to launch a bigger spaceplane including cargo hold for a rover and more DV
  20. TL;DR: is this generally considered a "don't do this" type of thing for spaceplanes, or just a tradeoff? Hi, I've been refining a Mk3 "do-everything" spaceplane for a while now (all science, ISRU, amphibious, etc.) and I'm wondering if I'm making a mistake with the balance. The default CoM is very stable and just a tiny tiny bit forward of the CoL, but I understand that although these being very close makes the plane more maneuverable, it also makes it more vulnerable to loss of control. My question is: is this generally considered a "don't do this" type of thing for spaceplanes, or just a tradeoff? —Liftoff/landing: CoM and CoL being on top of each other is good here, right? —Ascent: CoM being somewhat ahead of CoL makes the plane more stable. But if it seems pretty controllable then is there a reason to worry? —Reentry: CoM being somewhat ahead of CoL makes the plane recover from aggressive reentry profiles. Is it reasonable to say "I expect to have some fuel left to create this condition for reentry" or is that considered a bad design? (It needs 10% fuel to ensure recovery from radial out position) Basically, I like the idea of maximum agility (for a Mk3 spaceplane) but I don't want to overlook a fatal flaw.
  21. After much trial and error, I've finally managed to make my second ever functional SSTO, and the first SSTO I've ever created with a useful payload other then it's pilot! It's built to enter orbit, land on Minmus, spend about 2 and half months processing ore, then lift off to interplanetary space with 6,000 delta V to spare! Kerbal X Download Page Notes/Trivia: The crafts' front-most two fuel tanks are intentionally under-fueled! This was done to help achieve liftoff on the run way; when full, the craft was too unstable for me to fly properly X3 You might want to take this into account if you decide to refuel and take off on Kerbin. Alternatively, you can try to fly it fully fueled if you think your up to the task; I doubt I'm the best at flying :Y There's only one pilot seat and no probe control (making flying with an engineer not very ideal), and the ISRU module and drills are the smaller variants. Refueling takes awhile, even with stock speed up set to max! It does hit 4,000 delta V around halfway through refueling, so you can lift off partially empty if you know where you want to go, or need more TWR. Lift off from Minmus can be kind of tricky, as the craft doesn't have the reaction wheel strength to pitch up at full fuel, and the craft likes to curve after a while and slam one of it's wings into the ice! Simply retracting and rextending the landing gear quickly can help you ascend if you don't have a convenient ramp to use. Feel free to add your thoughts and/or suggest improvements, this is my first serious SSTO, and I'd love to keep building upon what I've learned while constructing it!

  23. This is my first craft thread, so advice would be welcome if I am in conflict with any conventions. LKO stats have been adjusted for 1.8 aero changes (improved performance for this craft). Big Plane to Anywhere (figuratively) https://steamcommunity.com/sharedfiles/filedetails/?id=1875714661 (Nice try, Bill, but I don't think this is what they meant by "long range ISRU craft"...) Well, it's been a long time coming. I'm mainly a rocket guy, but when I do find myself in the Spaceplane Hangar I very easily get obsessed with fiddling with my designs, more so than with the rockets. Anyway, I think I've finally gotten this to the point where I no longer have to be ashamed to put it in view of the public. Let me know if I'm wrong! If I'm being honest, the series of planes that this is a culmination of probably began life as the concept, "like my first spaceplane, only bigger". But eventually an actual mission materialized: to carry a scientific exploration team to Laythe and (almost) anywhere else with a complete science package and ISRU that wouldn't take months to refuel with. One development I'm a bit proud of was the realization that I could attach radiator panels to the reaction wheel that was adjacent to both of the drills and the refiner, elegantly taking care of all my core heat xfer needs. This development allowed me to finally have a truly streamlined airplane, since I had formerly had medium TCSes attached to the exterior. Two panels and two small TCSes have less than the mass of one of the two medium TCSes, let alone the aerodynamic improvement! The small TCSes (middle of picture) are for actual part cooling, and aren't necessary, but having at least a little active cooling capability is handy from time to time, e.g. cooling off during a multi-orbit aerocapture. (The panels are terrible at non-ISRU cooling in general, and the ones on this vessel in particular are nearly useless at it.) The construction of this spaceplane does not use offsets at all, nor any part clipping aside from the wings tilting into the nacelles. This was a design choice.

(counting ore tank, since you can refine it into fuel) —Engines: 4xRAPIER, 4xNERV (0.25 TWR on NERVs if the LF/Ox tanks are empty) —Landing gear: 2xLY-60 in rear; LY-60 and LY-35 in front. (35 for better taxiing and runway takeoff; 60 for rougher terrain and lower takeoff speed) —Mining: 2x large drills, large converter, 2x smallest ore tank, M4435 Narrow Band scanner, Surface scanner (Surface scanner can refine M4435's results) —Science: all experiments; 4 places to put science in addition to the lab (Cockpit, probe core, 2x storage unit) —Communications/Control: Communotron 88-88 (normal direct antenna); RA-2 + RC-001S (with one pilot, can control a probe that lacks direct CommNet connection) —Docking: 1.25m only; no RCS. See Miscellaneous for tips. —Airbrakes?: Yes, 4. Retract before landing. —Parachutes?: Yes, 6 plus 2 drogues; positioned to be moderately rear-heavy, but this is adjustable via fuel movement. Enables safe landing in any terrain or water. —RTGs?: Yes, 8; can permanently run lab and SAS at full strength —Fuel cells?: Yes, 3; can permanently run drills and refiner at full capacity —RCS?: Sort of; 6x Vernors under the nose to assist takeoff/landing in airless environments —How much delta-V is left after making LKO?: Even a pilot worse than me should reliably get to LKO with 24-2500m/s remaining before the +203 from refining the ore tanks. My best so far is 2667 (2870) and I seriously doubt this cannot be bested by an actually talented pilot. Test flight landed on Minmus with 1213 dV remaining. Also goes direct to Mun. —Amphibious?: Yes: can land in water on parachutes or aeronautically, and can take off from water (but only below 25% fuel). See Miscellaneous for details. Atmospheric flight characteristics: —Balance: The center of mass is almost exactly on top of the center of lift both full and empty, in the back half of the rear cargo bay. (About 16.3m from the front of the 26.8m craft, or about 61% of the way to the back.) If you want the CoM to move forward after takeoff, you can lock the tank behind the cockpit (this LF should not be needed to make orbit). This also can help counteract the already mild tendency to nose up at high speed (see below). See Miscellaneous for a tip about rebalancing the craft. —Lift: Tendency to nose up or down while SAS is off is not violent at any speed; very slight down at low speed (<200), a bit up at high speed (300-1000), and very slight up up during final speedrun. —Takeoff: Fully loaded, it can be lifted off the runway at 83m/s (lower on rough terrain due to upslopes) on main wheel (100 for smaller wheel). Consider using the small wheel on runways or flats to gain more speed before liftoff (due to lower angle of attack while on the ground). Left to its own devices it lifts off at the end of the runway at about 99m/s (112 for smaller wheel). —Ascent: After the 1.8 update, it no longer has to stop ascending to break the transonic speed hump. My flight plan, which may or may not be optimal, is: Set at 5° above horizon; it will gradually dip a bit to 2-3° but recover by itself. After going supersonic it will tend to slowly climb in attitude; stay at 5-7° until about 15km altitude, then begin dropping to 2-3° in order to extend final speed run in the 18-22km altitude range. (If you're feeling lazy, you can just let SAS do its thing all the way to 1000 m/s or so.) Activate NERVs when RAPIER thrust falls below 200kN. By the time thrust falls below 60kN you should be around 1500m/s +/-50; switch to rocket mode when jet+NERV acceleration is unacceptably low and aim for the top of the prograde circle (or a little higher or lower, to taste). When oxidizer runs out, drop to prograde lock; the NERVs should be able to maintain or increase your time to apoapsis. —Reentry: It's recommended that fuel be moved foward to the tank behind the cockpit for reentry for extra stability. For example, in testing, given a 100kmX15km LKO reentry orbit and only 500 units of fuel remaining, a neutrally balanced craft struggled to maintain a 40-45° pitch without using airbrakes, while a craft that moved that same small amount of fuel forward had no trouble. It should be noted that the balanced craft had no trouble with a 30-35° reentry profile. 1000 units of fuel (~10%) balanced forward is enough for a radial out pitch to stabilize forward instead of flipping out. Use caution if returning from other celestial bodies; it's not recommended to dig deep into the atmosphere on the first pass without decelerating first. —Landing approach: If airbrakes were used, retract prior to landing as the bottom ones may be destroyed otherwise. Perfect balance and generous control surfaces make it relatively maneuverable for a Mk3 spaceplane. Since it takes off near empty at 53-60 m/s (on big/small front wheels) the stall speed on low fuel should be similarly low unless I'm mistaken. —Landing normally: Try not to touch down at more than 5m/s vertical speed. The fairly wide rear footprint means it should be pretty stable and modest testing has borne this out. —Landing in water: This plane is capable of a safe aeronautic landing in water, which was successfully tested at 25% fuel, but parachutes are recommended for landing in water or very rough terrain. —Landing on parachutes: Even heavily loaded with fuel, this vessel can land safely on its complement of parachutes, but use of engines to help soften the landing is encouraged. The Abort action group opens doors for the parachutes and triggers them. Vacuum flight characteristics: —Takeoff: Fully loaded and on a flat surface, the Vernors are not quite strong enough to lift the nose for vertical takeoff in Munlike gravity. Instead, get forward motion and it should be able to lift off shortly with the help of the thrust attitude, especially if the vehicle runs off the top of a hill. Use of RAPIERs is recommended unless terrain is very flat. —Landing in vacuum: dV can best be conserved by a "reverse takeoff" posture, where final approach retains some horizontal motion while vertical motion is very low, but this is not easy. It is probably more practical to descend on the engines rocket-style, and then transition to horizontal when near/on the ground (fall on the wheels). This has been tested on the Mun. Be careful to keep the plane level (don't let it roll on its side or you may lose a wing). The Vernors can slow the fall of the front end, but this should not be necessary in Munlike gravity. Miscellaneous: —Recommended docking procedure with this vessel is as follows: 1. Rendezvous; 2. Make a close approach (50 meters dock-to-dock* or less), then cancel relative motion; 3. Align to the desired docking port, and accelerate a little for final approach. This technique has been highly successful on larger versions of this vessel docking with still larger vessels. *(Bear in mind that when approaching tail-first the engines are almost 27m closer to the target than the docking port, and flipping tail-to-nose will bring the docking port of this craft when normally balanced 32 or 33 meters closer to the target due to where the vessel's pivot point is. A dock-to-dock separation of 50m would mean a real distance facing away of 23m and 17m after flipping). —When altering the balance of the craft (e.g. to put the CoM more ahead of the CoL), keep in mind that adding fuel to the rear and front LF tanks in a 2:1 ratio will be approximately neutrally balanced, i.e. will keep or return the ship to close to its starting balance. —Water landing (via parachute) was tested on Kerbin at 75% fuel. If your splashdown attitude is close to vertical, your docking port may be at risk of destruction as you rotate down, but this can be prevented by using the Vernors to slow your fall. (Presumably similar precautions should be taken if landing on Tylo.) —The top speed in water is 38.7 m/s when full. The top speed on low fuel is uncertain because during testing the plane unintentionally took off. In subsequent testing, the vessel was able to intentionally lift off when top speed in water was about 70 m/s, when fuel fell to between 20 and 25%. (Highest speeds were obtained when fuel was moved forward and SAS set to prograde.) —Why the precoolers? Although the shock cones more than meet the needs of normal flight, I like the idea of having strong static airflow for those, ahem, "off prograde" situations. They are also handsome. —Why the everything? This design was not arrived at minimalistically; I'm sure there is a lot you could cut, starting with the rear parachutes and airbrakes. But I wanted a feature-rich craft, and those are features, and it is Minmus capable, so there. Having said that, I do still welcome criticism if you think anything is too blatantly unnecessary. —Why no offset? I just didn't want to use offset; a little bit to neaten up the often messy intersections of aerodynamic parts is okay but I often see it used in a way I think of as exploitative. So in a way the only minimalistic thing about this design is the offset and part clipping, which was a design choice. —After the 1.8 atmospheric changes, this plane can actually fly on a 3R+3N configuration, but taking away two nacelles worth of LF completely negates the benefit. It's slightly less dV, significantly less TWR, and a more annoying ascent path; why bother? Well, I could probably just yank one jet off the regular design (keeping 4 NERVs) and limp to orbit, but the dV gain (112 I think) is, while noticeable, quite modest and I would be nervous about sending it to Laythe untested with that much less atmospheric performance. So, how do you like the plane? How do you like the post? Comments and questions welcome. Edit history: 1.1—9/28/19: Added vacuum landing notes. Added "Miscellaneous" section.
