Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. If you have an account, sign in now to post with your account. If that's all a case of Too Many Words, think of it this way: Suppose you just build a plane the "default" way and don't put any. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Designing a High Altitude Jet | KSP: Making Space Home You cannot paste images directly. First is thrust; the higher you get, the lower the thrust your engines deliver. lost birth certificate near berlin; ksp high altitude plane. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. This is the first version. Even up there the plane acts squirrely. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. It has two modes: The first, Dry mode, is similar to that of the J-33 "Wheesley" Basic Jet Engine, with a bit more thrust. How do I install mods for Kerbal Space Program 1.1? - Insane TWR didn't help. http://www.youtube.com/user/Cruzanak?sub_confirmation=1Quicklinks to topics in this videoJet Engine Concepts: 0:30Air Intakes: 1:13Flameouts: 2:22Control Surfaces: 5:08Flying Tips: 5:57This video will go over everything that you need to know about to design a capable plane that can fly in the thinnest of atmospheres. It is designed to aid in player-controlled flight on generic (space)plane, providing a soft layer between user joystick\keyboard input and control surface outputs. As I understand, the OP wanted "the most efficient way to fly", and simply needed a bit of help in realizing that that is a hypersonic, high-altitude, high-performance aircraft which is a RAPIER and a little oxidizer away from being an SSTO spaceplane. Build a plane or rocket for Kerbal high altitudes - Arqade I recommend using a solid rocket booster (or 2 or 5) to you get you the altitude and then launch a small rocket powered plane. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. Proceed with caution. ksp high altitude plane. Its an approximation missing someelements. Either of the two speeds are to be avoided. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Ksp engine altitudes : r/KerbalSpaceProgram - reddit The maximum cruise altitude is just over 40,000 feet. Jets drop thrust at higher altitude and speed, but also drop . You cannot paste images directly. You can go above 20km with the J-404 Panther. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. I'm in career mode and got all groups of the 45-science-cost level, except Flight Control, and additionally have Electrics, Heavy Rocketry and Fuel Systems. Though I'm still working on learning to be better at space planes. Thanks. Something that I think has become less clear since someone updated the wiki. 1 1: The basics 2 2: Setting it up 3 3: First flight 4 4: Finishing touches 1: The basics First of all, you're going to need an airplane. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.. Visit Stack Exchange Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Satellite Launcher - Kerbal Space Program Wiki Challenges It may work with stock too, I just don't know. You can halve the drag by climbing a bit less than 3500m. By climbing, you reduce drag, exponentially with altitude. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. As high and fast as you can go without engine flameout: preferably ~2000 m/s at 25-30 km (and yes, that's almost orbital velocity). Only the fuel tanks attached to rockets have any oxidiser in them. What determines the maximum altitude a plane can reach? That will unlock: However, it seems as if your delta wing has has more area, might that be it? Been a while since I've flown stock*, but I've heard that, for maximum efficiency, you want one turbojet for every 7.5 tons, and about four ram intakes for each turbojet. There are two factors to that: how thick the air is, how fast the ship is going. @SaintWacko's advice is probably the most practical. You cannot paste images directly. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Now lets combine these two indicators: The best performance your engine can achieve is when you have an optimal amount of Air Flow (obviously) but also the MAXIMUM amount of Air Intake. Valve Corporation. You can post now and register later.

Kerbal Space Program ( KSP) is a space flight simulation video game developed by Mexican developer Squad for Linux, OS X, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. You need to do it with what you've got. How can this new ban on drag possibly be considered constitutional? ksp high altitude plane - digitalidentityorganization.com I looked into the .cfg files and there are no special properties allocated to them. high-2 A Screenshot of Kerbal Space Program The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. You could try combining the two. Create an account to follow your favorite communities and start taking part in conversations. Another problem is jet engines stealing fuel from the rockets' tanks - you may want to pump the fuel manually (requires an R&D centre upgrade) or add some pipes between them. As said above, the Wheesley is specifically designed as a low altitude engine. The most efficient way is, of course, to make a high altitude (or space) plane. More air is better. 1 Pod outside the level 3 VAB. Should i add a larger wing area for higher lift? At 3500m, you have half the drag you'd have at the surface; at 7km, 1/4 the drag, at 10.5km, 1/8 the drag, etc. This is my current best hi alt plane. You are simply running out of atmosphere (i.e. Kerbal Space Program - Wikipedia Note that KSP planes get one substantial speed benefit that's much more pronounced than IRL aircraft, due to the freakishly small planet sizes: they're actually flying at a large fraction of orbital velocity. This tutorial will cover designing and flying a plane that can soar at high altitudes! But since when do Kerbals wait for ideal conditions? With only panthers unlocked I might add. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. This thread is quite old. Don't be too surprised if KSP's aero model breaks down in edge cases. Thrust means that slower-is-better no longer applies: now, slower means less drag but more gravity, so there's a tradeoff (which I'm not going to carefully calculate for you, because it's hard). I did some testing and found that the turbojets get the best Isp around 5.2 km altitude, so I was thinking of flying at that altitude. You'll notice that usually your prograde marker is slightly below your pitch. Trying to do something without the right part is long and difficult path. First off as of .15.1 intakes don't do anything. - Spamming airintakes didn't help. Here's my example of dealing with the situation. Clear editor. In this case lots of fuel is the wrong approach, I can get more than half way around Kerbin on 2 cans of Jet Fuel and a turbojet if I glide most of it. At altitude the nose goes up and down until it goes out of control. Isn't that backwards snark? The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. There is a very close tolerance to the two speeds. Why not keep the engine for multi-stage rockets? - Space Exploration A destructible memorial to the old Mk. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. Long distance airplane flight tips? - Kerbal Space Program Forums Your link has been automatically embedded. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. It may take some practice to hit your target area this way, because you'll be picking up additional horizontal speed, and thus it's possible to under or overshoot. Thanks for the help! Designing a High Altitude Jet | KSP: Making Space Home Mike Aben 24.8K subscribers Join Subscribe 85 Share 3.4K views 1 year ago Ep. This thread is quite old. Why is there a voltage on my HDMI and coaxial cables? What are the minimum altitudes for each warp level? Your link has been automatically embedded. Grichmann's answer has been the most reliable way I've found to complete these missions. Using very light "engine rich" planes and "reverse swooping" (building velocity at 10km then gently curving up) you can temporarily get above 20km with Wheesely and Juno. 1Altitude requirement 2Orbit 3Speed, range, and altitude 4Flight duration 5Flight profiles 5.1Ballistic missiles 5.2Tourist flights 5.3Scientific experiments 5.4Sub-orbital transportation 6Notable uncrewed sub-orbital spaceflights 7Crewed sub-orbital spaceflights 8Future of crewed sub-orbital spaceflight 9See also 10References Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Originally posted by lord bird: yep thats right jool has a surface. Since gravity is effectively lower, they don't need as much wing area to maintain altitude-- which, in turn, means less drag, which makes for more efficient flight. Cheers again fellas. Are you using Stock or NEAR/FAR? You also need to be going very fast to generate adequate lift at high altitudes and unlike the real U-2, you don't need to fear about overspeeding and destroying the plane. If drag were the only concern, at any given altitude the slower you go, the less fuel you need: the work done by drag over a distance grows linearly with speed (the force grows quadratically with speed, but the time falls linearly). Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. Can't remember where I saw/read about it - Scott Manley maybe? This means it is better to have excessive amounts of oxygen than not to. I am currently designing a mission that will involve several very long distance plane flights. But my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. As long as the engine gets enough air it will work at proper efficiency. This lowers their effective "weight"-- for example, a craft flying at 1400 m/s on Kerbin is effectively flying as if gravity were only 2/3 of its actual value. All other versions are slower and lower and unstable in turns. Planes and Altitude differences. :: Kerbal Space Program General Really. - but they were talking about having two intakes/engine. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Your decreased flight time means you probably won't make it to your location. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. I've been finding it difficult to build a jet that can fly over 15km alt. Note: Your post will require moderator approval before it will be visible. So long as there's only one high-altitude measurement to take, you should be able to complete a whole set of 3-4 in one flight. To get higher with the low tech jet engines, you need rocket assist. Is it correct to use "the" before "materials used in making buildings are"? Of course, this thing has very limited range, speed and acceleration because of the extra weight. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. This thread is quite old. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. You can post now and register later. Using Kolmogorov complexity to measure difficulty of problems? Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. This causes the body of your plane to generate additional drag. Note: Your post will require moderator approval before it will be visible. One problem is i'm running stock on career mode and only have 30 part to spare, so large planes are out of the question. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Have you checked out the wiki yet? Now I have a plane that will fly around the world at an altitude of the low-20s. Upload or insert images from URL. Powered by Invision Community, Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane, I was generally under the impression that basic jets were mostly deadweight on high-performance aircraft: [] at hypersonic velocities. Will post my results. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Is there a single-word adjective for "having exceptionally strong moral principles"? KSP - High Altitude Aircraft 16,702 views Jan 22, 2016 172 Dislike Share Save Phoenix Fleet Systems 222 subscribers Have a type of atmospheric craft you'd like to see me experiment with? Evidence. For more information, please see our i dont know what kind of range youre looking for but i would make a significantly smaller plane. Pasted as rich text. I should perhaps start trying out NEAR to get ready of 0.90, though. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General - Insane lift to weight didn't help. My question is really about controllability. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. Build a plane or rocket for Kerbal high altitudes, We've added a "Necessary cookies only" option to the cookie consent popup, Screenshot of the Week #85 [Submissions Closed - Vote Now!]. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.
