I am currently designing a mission that will involve several very long distance plane flights. *I use FAR these days, which basically means completely replacing every spaceplane and rocket you ever designed to account for its much more realistic aerodynamics. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. 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. There are two factors to that: how thick the air is, how fast the ship is going. Thanks for asking this, I've been struggling with the same problem in career mode. Clear editor. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ The U-2 is probably the highest altitude aircraft still flying. If not, please explain why, which I know you have no problem doing! Whiplash is the engine you would want to use on a plane meant to go 20km. Building a High Altitude Jet | Stream pt. So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Cookie Notice 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. June 3, 2022 . Anyway thanks in advance. Basically you just need to fiddle with it and try some test flights. I don't have that other stuff yet. Do plugins for Kerbal Space Program work on unix? First off as of .15.1 intakes don't do anything. I was generally under the impression that basic jets were mostly deadweight on high-performance aircraft: while they are superior for low-speed, low-altitude operations, they become deadweight at hypersonic velocities. 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing. Is there a single-word adjective for "having exceptionally strong moral principles"? Rockets aren t the only way to get to space. Hopefully this will be helpful to you. principle. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. All the information you could want to know about science, including the altitudes for each celestial body, and what altitudes a given experiment works on are available at: http://wiki.kerbalspaceprogram.com/wiki/Science. At about 400-500m/s (~15km), the two engines are even. Grichman's answer got me in the right direction. 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. What's the difference between a power rail and a signal line? Display as a link instead, 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. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space You cannot paste images directly. Also, jets eat fuel at pounds-per-minute -- if you cover twice as much ground in the same time, your plane will be more efficient. Building a rocket to fly vertical seems to be nearly impossible, in the atmosphere they tend to become unstable (or maybe I missed a trick?). I also added a parachute and decoupler since I find it too hard to correctly land this thing yet ;-) I managed to land in the water once, though. My 'plane science' is more advanced than my 'rocket science' (career mode) because I got tired of seeing all the high-altitude missions I had on the books and wanted to finish them. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". The Panther engine can hold 19,000 steady and oscillates around 20,000. [Solved] 30 20 / Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Exorcet's Content - Kerbal Space Program Forums Remember that you need to have intakes somewhere in line with the engine to function at that altitude. At sea level, it produces 120 kn thrust, but at 15 km altitude, it only produces 13.7 kn of thrust, barely enough to provide any thrust to climb higher, Long and narrow wing has less surface area to provide lift, and at higher altitude, the atmospher is so thin that the lift generated by long and narrow wings is insufficient for sustainable flight. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? i dont know what kind of range youre looking for but i would make a significantly smaller plane. If too little air runs into the turbine your combustion chamber will not be able to burn up fuel effectively due to the lack of oxygen. 2022 Take-Two Interactive Software, Inc. Is anywhere a list of the altitude levels (I don't know a better term) available? Main goals: Auto-trimming. Not only does it conk out at high altitudes, but also it conks out at high speeds, and you need to be able to go fast to fly up high. Why do many companies reject expired SSL certificates as bugs in bug bounties? Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. even stranger is that the surface is textured. The longest flight got them down to a little more than half full. List of altitude levels? - Forums - Kerbal Space Program Forums Why is there a voltage on my HDMI and coaxial cables? Double your speed, you need twice as much fuel. - Insane lift to weight didn't help. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate 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 also had problems with a high altitude plane until I decided to follow the K.I.S.S. 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!]. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Steam Workshop::damn wow Using Kolmogorov complexity to measure difficulty of problems? Clear editor. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. If you've attached them to your fuselage with zero AoA, what that means is that when you fly, you're going to have to have the entire plane pitched slightly above in order to generate lift. Kerbin | Kerbal Space Program Wiki | Fandom The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. This means it is better to have excessive amounts of oxygen than not to. Chapter 4. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. I'm trying to build a high altitude plane and have found out that the rules are different. 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. with a thrust vectoring range of only 3 degrees. 1 Pod outside the level 3 VAB. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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. I would like to know which altitude I have to maintain for my experiments. Or is it the same for all celestial bodies? Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. (the engines will use very little at high altitude anyway). Arqade is a question and answer site for passionate videogamers on all platforms. Why not keep the engine for multi-stage rockets? - Space Exploration Reddit and its partners use cookies and similar technologies to provide you with a better experience. At altitude the nose goes up and down until it goes out of control. Note: Your post will require moderator approval before it will be visible. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. This works, but it's not optimal. 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. 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. Put a couple of radial mount parachutes just above the com and add a reaction wheel. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. You arent doing anything wrong. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. surface of jool. I've been trying my hand at some High altitude speedy planes for a while now, but can't seem to get a hang of the altitudes that each engine likes, I know kerbal isn't earth, so looking up the crushing altitude of say the sr71, doesn't seem to apply, but I was hoping that others experiences would help me. You cannot paste images directly. I looked into the .cfg files and there are no special properties allocated to them. How can this new ban on drag possibly be considered constitutional? Powered by Invision Community. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. Your previous content has been restored. 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. Pasted as rich text. Pvt. CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General With only panthers unlocked I might add. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. The other one I stay around 6000 meters. Slap that behind a plane you'll be able to go beyond 20km without any trouble. A full suite of flaps on the trailing edges of the main wings give it exceptional low-speed lift, and small hydroplane steps mounted on each side of the fuselage bottom help lift it out of the water (lowering water drag) during takeoff runs. But since when do Kerbals wait for ideal conditions? KSP Career: Episode 13 - High Altitude Surveys Mike Aben 28.5K subscribers Subscribe 7.7K views 7 years ago Day 114: A busy day at the KSC with three missions, the highlights being the launch. Jets drop thrust at higher altitude and speed, but also drop . Jet engine - Kerbal Space Program Wiki Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. One of my planes is small and agile, and can easily enough glide to a safe landing even if the rockets consume all the fuel. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Here's my example of dealing with the situation. You are just about at maximum speed and at the same time very close to stall speed. I followed a similar strategy. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Designing a High Altitude Jet | KSP: Making Space Home KSP also tends to have very harsh induced drag if angle of attack gets too high. - Insane TWR didn't help. 2022 Take-Two Interactive Software, Inc. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) For example, the RAPIER engine doesn't seem as the first choice as the "best" high altitude air-breathing engine but in long-distance and high-altitude challenges it is. It flames out at 25,000. But you'll need to unlock: Which cost 300 science. - "In Space High" means your craft is inside the given Sphere of Influence and above the "Space Border" altitude listed in the Celestial Body Multiplier Matrix. I'd almost expect it to work better in stock since infini-gliders can be done. Note: Your post will require moderator approval before it will be visible. I was even able to do this with three pairs of Junos instead of the large jet engine pair (I don't have the technology level for that). 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. If you nudge your wing's angle up slightly with rotate tool then it'll move your prograde closer to your direction of flight and significantly reduce drag. TLDR: You need parts you don't have to make a plane that flies that high. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Originally posted by lord bird: yep thats right jool has a surface. Paste as plain text instead, 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. "Whiplash" Turbojet. Planes and Altitude differences. :: Kerbal Space Program General Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. When I say ", You know you've nailed it correctly if, when you're in level flight, your. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. 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. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. With the tanks disconnected that way, the rockets don't leach from the jets. 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? It will be expensive and time consuming. Kerbal Space Program - All Easter Eggs Guide Though I'm still working on learning to be better at space planes. It was meant for low altitude flight. Your link has been automatically embedded. Should i add a larger wing area for higher lift? Tutorial: Making the AI fly | BDArmory Wikia | Fandom Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! What are the minimum altitudes for each warp level? if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. Yes. Trying to do something without the right part is long and difficult path. Grichmann's answer has been the most reliable way I've found to complete these missions. Planes in Space. 3x06: I design a new, high altitude, jet to collect high. New comments cannot be posted and votes cannot be cast. A destructible memorial to the old Mk. The second, Wet mode, uses the afterburner to produce thrust almost equal to the J-X4 "Whiplash" Turbo Ramjet Engine, but at a considerably reduced fuel efficiency. Yes. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube Kerbal Space Program 2 . Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Long distance airplane flight tips? - Kerbal Space Program Forums This page was last edited on 22 December 2019, at 20:54. Be sure to have enough intakes (I think maximum efficiency in stock is 1 ramjet intake per ~2 tons of plane, though that is aesthetically ridiculous), and if you're still running short of intake air, you can dip down a bit to speed up and get to denser air. Build a plane or rocket for Kerbal high altitudes - Arqade The SR-71 could probably fly higher, but it isn't flying any more. Press question mark to learn the rest of the keyboard shortcuts. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. I don't recall if they model aspect ratio, but either way, the struts are murder and the delta wing has so much more wing that it'll still have more lift. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. These designs are great for getting around Kerbin quickly, but without going orbital. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. : : . Ksp engine altitudes I've been trying my hand at some High altitude speedy planes for a while now, but can't seem to get a hang of the altitudes that each engine likes, I know kerbal isn't earth, so looking up the crushing altitude of say the sr71, doesn't seem to apply, but I was hoping that others experiences would help me. I've since shaved that down more but that was by going even higher and even faster). But maybe your patience? 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.

If it's above the cross-hairs, you need a little less. (Actually, four ways: but balloons aren't in the stock game) Lifting surfaces are great but they lose effectiveness just as fast with altitude as drag falls. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram
