  1. All I wanted was to figure out how much excess thrust I had for my spaceplane along its ascent profile. And then I wanted to know the lift curve slope and level flight AoA so I could program my kOS spaceplane autopilot better. Next thing you know, I'm writing a mod to work in the Spaceplane hangar to calculate flight envelopes, alpha curves, and so much more. And it works, sort of totally! Check out the release thread here: https://forum.kerbalspaceprogram.com/index.php?/topic/177302-ksp-142-kerbal-wind-tunnel/ This shows that the Aeris 4A has a ceiling of about 22km and a max speed at sea level of about 790m/s and a max overall speed of about 1360m/s at around 14km using its air-breathing engines. Then, at 15km and at 964m/s its level-flight AoA is 2.8 degrees and it has 365kN of excess thrust. Great! But now I want to freshen up the GUI (thanks @TriggerAu, but this was clearly designed for Transfer Window Planner ) and add in Lift, Drag, and L/D curves for a given altitude and mach number. I also want to move to using background threads for calculating (right now, I either hang the program for 20 seconds while it calculates that graph or put up with artifacts from my non-thread-safe implementation on the BackgroundWorker, as you can see). First, some credits: Thanks to @linuxgurugamer and @Boris-Barboris. I learned a ton about the aerodynamics model from your Correct COL mod. Also your method of drawing line graphs is coming in handy for the lift curves I'm working on drawing. Thanks to @TriggerAu. I learned a ton about making the graph from your Transfer Window Planner. And thanks to the MechJeb team. I'm using a lot of your tricks to make things more thread-safe.
  2. 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.

    ARCA Expendable Smallsat SSTO

    This had been discussed on the forums a few years ago, but now ARCA (a rather odd company that doesn't seem to know what its market is) has released a glitzy CGI video of its "Haas 2CAJ" smallsat SSTO launcher. While the company's track record isn't very good, the combination of technologies and solutions in their idea seems solid enough. Here's a bunch of specs on it. It's a 16-meter-high smallsat SSTO burning RP-1 and HTP with a projected payload of 100 kg to LEO, using a rather large linear aerospike engine and a composite frame/tank with common bulkheads. Claimed launch price is just $1 million. As these things go, it's not a bad idea. HTP/RP-1 is about the only non-exotic prop combo with a higher impulse density than kerolox, and it also permits higher thrust than kerolox, which helps make up for the lower TWR of linear aerospike engines. It's pressure-fed, which would typically be the death knell for an SSTO, but since the linear aerospike engine doesn't require a high chamber pressure it's not a bad idea. Pressure-fed engines also typically have very poor tankage ratios, but the composite tanks can handle higher pressures. The pressurant is liquid helium that is passed through an engine heat exchanger, simultaneously cooling the big aerospike engine and saving on the weight of a turbopump, which further mitigates the low TWR of the aerospike. The linear aerospike allows for roll, pitch, and yaw authority through differential throttling alone, which saves on the mass of a gimbal system. The use of HTP comes with its own set of handling challenges, but it is cheaper than LOX, requires no insulation, and requires less demanding materials specifications than LOX. All in all, not a bad concept. Whether they will pull it off or not, I don't know. They fuss and fret over the horrors of staging, but honestly this could be very competitive if it was offered with the option of COTS parallel SRBs. Base configuration for smallsats, a couple of SRBs for larger LEO comsats, or a quad of SRBs for big LEO comsats or GTO smallsats. Better than trying to fuss with a second stage.
  5. Howdy. It took a while but i finally finished work on my little movie. It is over a hour long video split into 8 parts. I would like to thank all the Modification authors for their great mods. You are the giants on which my little movie stands. Thank you Enjoy ;-)

    Ideas for rockets

    I am having trouble thinking up rocket designs this thread is about giving design to the community and help people if they are stuck (like if they can’t get to a planet.) no real rules at this point in time but I will make some up in the near future. You can post wacky rockets or really cool planes, SSTO, really weird missions and stuff like that. Everyone is welcome. Be nice. If you what to tell a community if you made a mod you can post the link in the thread. Most importantly have fun

    SSTO - orbital adventures

    I've been playing about with some vertically launched SSTO's after a few weeks ago making my first of these. That one didn't have the ability to return (safely) to the surface, so I rectified that today. Mk1 Only a tiny payload volume inside a payload bay, that it shared with solar arrays, and parachutes etc. A crew of two takes this to orbit. Worked well enough for a first stab at this. Went for a land touchdown, rather than splashdown. The flat terrain allowing it to balance on the aerospikes. Mk2 A straight forward "bigger is better version, with a longer payload bay. As with all of these designs, a lare part of re-entry was a case of just letting the vehicle spin to pick up drag and spread heating, rather than a nice controlled descent... but hey, it works. Upper half of the open payload bay, plus another one (closed in this image) available for cargo. Plenty of heat on the return. And a comfortable 7.4m/s splashdown. Mk3 A payload only vehicle this time, that delivers 5 tons of playload to an 80km orbit. Launch was uneventful. Left with decent amount of fuel for circularisation. Separation of the payload. One orbital habitat, ready for business and for more deliveries to join it in the near future, to create a larger station. Another "wobble, wobble, but ok in the end" re-entry.
  13. Welcome to Spaceplane Innovations, the online leader in executive Spaceplane sales. Dropping tanks is so yesterday, earn back some self-respect by going fully-reusable today! We have Interplanetary leviathans and nimble Mun Hoppers, Single-stage-to-anywheres and Cargo-carrying brutes. All capable of high crew capacity and total galactic dominance. Shop now, the SSTO of your dreams is just a click away. We also make rockets. View the full catalogue! Click to view the full catalogue! Artemis Class These spaceplanes are the biggest of the bunch (so far), consisting of 3 Mk3 fuselages side-by-side, with the ability to carry an enormous amount of cargo/crew to many different interplanetary destinations. The Archangel is the first of the Artemis line, and has the ability to easily go to Duna or Mun with 60 Kerbals, and pilots who have a good grasp of gravity assists will find further destinations, such as Eeloo, very possible as well! Video - Mun mission Video - Eeloo mission The Artemis is a monstrous spaceplane capable of carrying 124 kerbals to LKO with just over 4,000 m/s of DeltaV to spare. It can't fly quite as far as the Archangel, but it is quite capable of going to Laythe and back without refuelling. Video - Laythe mission Archangel Download Archangel Download Archangel v2 Download Artemis Download Argus Class These spaceplanes are big, brutal, and capable of interplanetary missions without breaking a sweat, independent of mining or refuelling. WARNING: You will need to replace the landing gear on the Argus II and Engadine with larger ones if you're playing in 1.1 or later. The Odyssey will work fine though. The Argus was built as a Bop SSTO, but in the end was mainly used for Duna cargo missions and Eeloo voyages. It doesn't work so great in 1.05, and so is no longer sold by Spaceplane Innovations. Video - Eeloo mission Video - Duna mission The Engadine was the hugely popular successor to the Argus, packing more DeltaV and a massive 20 Kerbal capacity. So far it has only been used for Mun landings, but we at Spaceplane Innovations believe it could easily be used for Duna returns too. Video The Argus II was built following the success of the Engadine as an ultra-long-range SSTO. It has more m/s of DeltaV in LKO than any other SSTO produced by Spaceplane Innovations. Video The Odyssey was built to replace the legendary Engadine. doubling its crew capacity while retaining its high range. Duna and Gilly missions are well within its capabilities, as well as Eeloo and Jool for those who have mastered the fine art of gravity assists. Video - Mun mission Make no mistake: these planes are unruly, bulky, unbalanced and difficult to tame. They are therefore best suited to more adept pilots who understand gravity assists and how to efficiently ascend from Kerbin. They're hard to master, but for those with the patience to learn their functions the pay-off is huge. Argus II Download Engadine Download Odyssey Download Acacius Class Acacius ships have an IRSU on board and are capable of refuelling themselves using mining equipment. These are at the forefront of exploration, and are the best "single-stage-to-anywhere" planes we offer! Only one model is currently available for consumers: The Acacius 2 is the first SSTO produced by Spaceplane Innovations to feature the "Single Stage to Everywhere" guarantee. Doesn't do Tylo. Or Eve. Or Jool. These craft are ideal for beginners who want to get to grips with gravity assists or the Jool system, without having to worry about fuel. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. Video Acacius 2 Download Dune Class Before the Argus class, there was the Dune class. The second oldest class of spaceplane made by Spaceplane innovations (after the discontinued Revenge class), these are lightweight, agile, and pack enough DeltaV for Duna, Minmus, Mun and Gilly. Flybys of planets further out are also possible. Dune 3 is the latest and greatest in this class, sporting 3 seats and a cosy interior. These are moderately difficult to use, but experienced pilots shouldn't have too much trouble. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. Video Dune 3 Download Phantom Class These SSTOs are the little-brothers of the Argus Class, and are slightly larger than the Dune class. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. With room for 6 kerbals, the Phantom class is currently offers 3 models: The Minmus Trainer is the easiest-to-use SSTO sold by Spaceplane Innovations, and was specifically designed to train budding kerbalnauts in the fine art of Minmus SSTO-ing. Only the instructions are available for purchase, so that pilots can also learn how to build an SSTO too! Video (SSTO Tutorial) The Mun Phantom was the first Phantom Class SSTO packing enough DeltaV for Mun and Gilly landings, in addition to being able to do Duna flybys. Video The Mun Phantom 2 is a modified version of the Duna Phantom, packing a spacious cargo bay for all your rover carrying needs! Video The Duna Phantom is able to carry 6 kerbals to Duna and back, all in a sleek Mk2 fuselage!

    Laythe SSTO Follies

    Hello, to anyone who is reading this post. I have ideas for Laythe SSTOs & I need need some help in fixing my crafts so they can live up to my expectations. Feel free to reach out to me & help me on my goals!
  15. I always thought that with the use of ions and gravity assist that an exoplanet mission wasn't too far out of the question. So I gave it a try and... Big thanks to @AndrewDrawsPrettyPictures for making the Extrasolar system pack which is used to add the exoplanet into the game. You did a very good job with everything, from the design to the visual enhancements.
  16. Hey there forum goers! My name is of course, SpaceplaneAddict and welcome to Addiction Aerospace, my SSTO repository. If the name and stuff is to RP-ey, then I'll change it, no biggie. Anyway, I'll be posting SSTO's and occaisonaly other junk (A.K.A Failed stuff maybe, plus rockets). Enough talk! The BadS SSTO, featuring everything you need in an LKO SSTO! Anyway, as I said, this is a basics SSTO, has everything needed for LKO, such as RCS, Docking, and a good Delta-V margin along with unmanned capacity. To fly, well, I'll just say it's a mid TWR vessel. I'll have details for flight below somewhere. I forgot, have a download link The Blade, SSTDuna and maybe back! This SSTO here is my first ever interplanetary capable SSTO! Anyway, acsent profile is sort of tricky, but doable if I can orbit it! 10 degree acsent all the way. At 8km pitch up to 15 degrees. At 15km, pitch down to 5 degrees. Slowly rise to 10degrees and hold it there. Light nuke when combined RAPIER thrust is below 180. Switch mode to rocket when total thrust is below 100. Fly to Space! Action groups: 1 - Toggle RAPIERS 2 - Toggle RAPIER modes 3 - Toggle Nukes And I'll take that, to go. The Mercenary, a 1 Kerb Dune Buggy! Well, rovers are self explanatory. Originally designed for the Elcano, beware of high speed turning. Though it has 2 small reaction wheels, turning speed is around 15 m/s. And, you can't argue those looks! Get yours today for only Free thousand Funds! Persistance, two stage to Minmus Spaceplane! As the picture shows, the spaceplane end looks like a normal longb range Nuke-RAPIER combo, but on the nuke, is a decoupler, and a "Thumper" SRB! The SRB is for an orbital kick, shooting you (if shallow acsent if used) to a 50km or so Ap, and pushing T-Apoapsis to a near 1 minute 45 seconds away! No instructions for this one, hehe, just pitch 10 degrees near the lower altitudes. Get yours today, for almost 45 THOUSAND Funds! Pickaxe, a Mk3 Infinirange Mining Spaceplane (SSTO)! Well, as stated, it's a simple trick of carrying a mining kit everywhere you go. Can handle EverythingTM except Eve and Tylo. Flight instructions: None. Pitch according to thrust output. If thrust is increasing, pitch to the point it is barely increasing. Pitch level at "speed run" altitude. Action Groups: 1 Toggle RAPIERS 2 Switch RAPIER mode 3 Toggle Nuclear rocket Buy ten, get 1, COMPLETELY FREE! The Alouette, my competitor to @Rune's White Dart! Space station not included Designed to have the same functionality of the White Dart, it is just as modular, and (probably) as dragless. Power comes from the Whiplash jet, and the dual Thuds, radially mounted, then offset. Flight Instructions: Pitch acording to thrust. Get yours today for about 2 WHOLE FUNDS! WHOOOO! Anyway, that's all for now, hoping to get some newer, an different ones out later. -SPAddict

    ssto questions

    ok, here goes. 2. is the "reach mach 1, reach 10 km, reach orbit" or the "reach mach 3 at 150 meters or below, pitch up to 10 or 15 degrees, reach orbit" ascent profile better for heavy cargo ssto? 5. is 1 whiplash and the rest nuclear engines and rapiers better than just rapiers and nuclear engines all help is appreciated .
  19. X-84 Akkadian at KerbalX The X-84 Akkadian is my attempt at the Ultimate Challenge: Visit every body and moon in the Kerbol system. As a bonus: visit also every planet and Moon in the Outer Planets mod. The vessel consists of three parts: - X-84 Akkadian SSTO - X-84a Ishtar Eve Lander - X84b Traveller Probe core The Akkadian is the workhorse of the mission: It is able to lift itself and the Eve lander into low Kerbin orbit. It has enough delta V to reach Moho from Eve. Enough thrust to land and take off from Tylo or Slate. And, it is sufficiently aerodynamic to land and take off from Tekto. Three Kerbals can travel comfortly and collect science from almost everywhere, except Eve. The Ishtar Eve lander is being lifted to orbit and carried through space by the Akkadian. All is needed are four additional Whiplash Engines and some wings. In order to save some weight, the lander is only equipped with a command chair for one Kerbal as well as some basic science experiments. Also on board is the Traveller probe core. The Traveller probe core is the key to fullfill the Ultimate Challenge: the contract requires a command module or probe core to land on every single planet and moon. As the Akkadian cannot land and take off from eve, and the Ishtar is not built to travel to every other body, the Traveller Probe core is the solution inbetween. It will land on Eve with the Lander. After reaching orbit again, the small probe will dock with the SSTO for the remainder of the voyage. The vessel is surprisingly cheap: the whole package costs under 300.000 Bucks. Take-Off weight from the runway is under 150t. And, practically no clipping was involved. Some specifics for the Akkadian Maximum mass: 109t Max Liquid Fuel: 10180 Max Oxidiser: 4620 Crew capacity: 3 Krew Range and Fuel Profiles: Max Range (10180 LF / 0 Ox): 7023 m/s dV Low Ox (10180 LF / 1000 Ox): 6400 m/s dV Max High Thrust, Chemical Rockets only (3892 LF / 4620 Ox): 2592 m/s dV Use Max Range, if target has low gravity suitable for Nerv only landing (Gilly, Ike, Bop, Pol, etc.) Use Low Ox Range, if target has medium gravity and Nervs require assist from Aerospikes / Rapiers (Moho, Duna, etc.) Use Max High Thrust for landing and take-off from Tylo. Remember to pack additional LF (800-1000 LF) for take-off from Tylo and transfer to Pol. Engines 3x Rapiers (Action Group 1 to toggle, AG 2 to switch mode 2x Nerv (AG3) for interplanetary travel 2x Aerospike to provide additional thrust for high-G landings (Tylo) or more efficient Oxidizer use. Aerospikes have 340 sec vacuum ISP vs. 305 sec from Rapiers in rocket mode. Also, it has 4 detachable Whiplash Engines to lift the Ishtar Eve Lander into Orbit. Ishtar Eve Lander The Ishtar Eve Lander is built to be lifted in front of the Akkadian into Orbit. For this, it has a detachable set of wings and control surfaces. To provide the necessary thrust for ascent, the Akkadian has four detachable Whiplash ram jets. The Ishtar has a first stage with one Vector engine and six asparagus-staging drop tanks, the first two with additional Aerospikes. The second stage is powered by one Terrier and two drop tanks with Sparks. The whole ascent vehicle has enough delta V to reach orbit from sea level with moderate skills. (You’ll have to know the atmospheric properties and general Eve ascent profiles, though. When in doubt, search the KSP forums or watch Eve ascent videos on Youtube.) Maximum mass: 56t with wings, 49t lander only Science Complement: 4x basic experiments (Thermometer, Accelerometer, Barometer, Gravioli Detector) Electricity: 2x solar panels in the Traveler Probe, 2x fuel cells on landing legs.
  20. I built this Andromeda class SSTO the other week, the intended use being space station components, which are bulky but light. I tested it with a 2.5m Xenon powered ship as the heaviest plausible payload (18t), because if your lifter is NERV powered, why would you go back down to chemical ISP for the deep space part? But the gold standard for a mk3 SSTO is an orange tank (36T) , so it had to be done... A design like this lives or dies by it's lift/drag ratio, namely you must stay as close to prograde as possible to minimise drag from the cargo bay. Aerodynamically, it's designed to do that when empty, and i've added trim flaps on action groups 1-3 to nudge the angle of attack a few degrees higher or lower so you can adjust the flight path. However, the positioning of the cargo can upset this. The orange tank caused it's AoA in Neutral trim to shift to almost 2 degrees nose down , due to the cargo being slightly too far forward. I was able to work around this by operating with nose up trim most of the flight and tweaking the deployment angle of the trim flap, as i'm sure you could if you had the luxury of an analog stick ! In future though, i'd recommend test flying with the payload before shooting for orbit, and see where the natural AoA goes to so you can see if the cargo needs to move at all. Or just get a fancy-ass analog joystick ! https://kerbalx.com/AeroGav/Andromeda Is it the smallest thing to ever lift an orange tank?
  21. Hi all, first post here! So, I'm in career mode, with the majority of the tech tree unlocked (rapiers etc, but no MK3 spaceplane parts yet...) I have a rather large assembly plan for a rather large multi purpose space station. SoI need a cost effective (hopefully reusable for realism) LKO capable vehicle with the largest cargo capacity possible. Any ideas? Options thus far and their problems: 1. SSTO - probably with rapiers, but these are hard to design, and cargo capacity seems limited unless I go massive, and I mean massive 2. Recoverable booster (spacex style) - design wise this should be easier, with optimal cargo capacity, however landing the damn thing is a fair task... I have a mechjeb available (landing guidance) which could work, but surely I would need a mod to fly multiple ships at the same time. I'm willing to try my hand at KOS if it would work? Which of my two options is the best way forward, and how best to implement this in ship and mission design and execution? Or is there an option I haven't though of?

  23. Put the most S4-512 fuel tanks from Making History into orbit at one time using an SSTO Rules - No cheating - Stock and Making History parts allowed - No part mods - S4-512 tank must actually be full of fuel - SSTO must return to Kerbin (KSC landing optional but preferred) - Most S4-512 fuel tanks launched wins - Must take off horizontally, it would be too easy to simply add a bunch of Saturn Vs to boost the thing into orbit. Leaderboard 1. @JacobJHC - 1 fuel tank 2. 3. 4. 5. 6. 7. 8. 9. 10. My entry to prove it is doable:
  24. (I've posted this before, but that was a long time ago, and I want to get back into the community, so here goes. Sorry if I shouldn't post this again). The Grus III is a long-range SSTO capable of Mun landings, though according to my Delta V calculations it can easily go well beyond that. It can get into orbit very easily due to its high TWR while using its Rapier engines. Its (roughly) estimated Delta V in LKO is about 4,150 m/s (usually a little less). Specifications: Part Count: 97 Mass: 80.545t Height: 5.8m Width: 22.8m Length: 25.6m Here it is on The Mun. It can make the trip easily as it was designed for bigger missions. It is also equipped with four science experiments, located on the belly of the craft. Here it is in the SPH. Some (kinda) strange features are its extra pair of engines. While very helpful during the initial ascent, extra reaction wheels are needed in space to prevent the Grus III from flipping all over the place due to the weird Center of Thrust. (At least this isn't the case with the nukes, though. That would be bad.) The Grus III completed the Mun trip with quite a bit of fuel left over. I've also taken it to Minmus, and Duna orbit (landing it was to hard to bother). Download here: https://drive.google.com/open?id=0BwpycuAS_53bcXdYMDl1MEhBV2s
