But you'll need to unlock: High Altitude Flight Which cost 300 science. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 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. It's Kerbal Space Program v.22! This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. 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. 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. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Let me share what I know about jet engines, speed, and efficiency. Spaceplane - Wikipedia That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Hello there. It's also worth noting that this engine has the widest thrust vectoring range of all of the jet engines, with a full 10-degree range in all directions. 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. They will someday, but they don't now. Jet engine - Kerbal Space Program Wiki 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. Note: Your post will require moderator approval before it will be visible. 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. 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. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ In the main KSP settings menu you should set the default throttle to 1.0 (technically the above mechjeb setting winds up restoring the default throttle, so it needs to be 1.0) In the attitude adjustment menu make sure you are using the "better controller" Whack the 45 degree phase margin button Whack the restore all other defaults button Note: Your post will require moderator approval before it will be visible. I've been finding it difficult to build a jet that can fly over 15km alt. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. As long a you can fly faster, the lower density at altitude can be compensated for. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. FAR is supposed to take aspect into account, but I'm not very experienced with it and cannot advice you as to how it works. 1.) Delta-v budget - Wikipedia - Spamming airintakes didn't help. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. 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. and our This thread is quite old. What are the units of measure used in Kerbal Space Program? It only takes a minute to sign up. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Beginner's Guide: Tips and Basics - Kerbal Space Program 2 Wiki Guide - IGN Any advices for building a vehicle for this task? Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Paste as plain text instead, 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). Create an account to follow your favorite communities and start taking part in conversations. 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. The ideal case for optimally efficient flight (which is what you want if you're trying to maximize cruise altitude) is when your wings are mounted to the body, pitched up just enough that when cruising in level flight, the body of the aircraft is pointing perfectly . Either finish the low-altitudes and then spend all your fuel on the high-altitude boost, or do the boost first and save a little fuel or try to hit the rest through unpowered gliding. - but they were talking about having two intakes/engine. All trademarks are property of their respective owners in the US and other countries. lost birth certificate near berlin; ksp high altitude plane. Or try using SRBs instead. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. List of altitude levels? - Forums - Kerbal Space Program Forums This is the first version. How to tell which packages are held back due to phased updates. Press question mark to learn the rest of the keyboard shortcuts. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. The drag differential is because your long-wing layout is using a bunch of struts, and the reason your delta-wing has a higher ceiling is because it has more wing area to provide lift. 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. If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. Welcome to the forums, ZDW. Please consider starting a new thread rather than reviving this one. So that means that even if you are inside the atmosphere but still orbital (such as during aerobraking), your science will not count as "Inside the atmosphere", For example, orbiting Kerbin above 250km altitude, your science is counted as "In Space High over Kerbin." Don't be too surprised if KSP's aero model breaks down in edge cases. In addition to the traditional giant tube of explosions that flings things up high approach, Kerbal Space Program includes a very useful piece of equipment that became quite popular in the 20th century: wings.. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. 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. The U-2's published maximum altitude is somewhere above 74,000 feet. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Your link has been automatically embedded. 2022 Take-Two Interactive Software, Inc. It flames out at 25,000. How do you get out of a corner when plotting yourself into a corner. The most efficient way is, of course, to make a high altitude (or space) plane. Pasted as rich text. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. Control Sensativty for Planes - KSP2 Suggestions and Development Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. alternatively, combine a liquid fuel rocket into your plane. Originally posted by lord bird: yep thats right jool has a surface. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space Pasted as rich text. To get there, you're going to want to climb at the fastest rate you can manage to 18-20 km, at which point you should mostly level off and start accelerating horizontally. The Panther engine can hold 19,000 steady and oscillates around 20,000. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. You are just about at maximum speed and at the same time very close to stall speed. You can post now and register later. Trying to do something without the right part is long and difficult path. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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. Then it is "In Space Low over Mun.". KSP also tends to have very harsh induced drag if angle of attack gets too high. At altitude the nose goes up and down until it goes out of control. 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. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. How do I install mods for Kerbal Space Program 1.1? That's because wings need to have some AoA to the airstream in order to generate much lift. Your link has been automatically embedded. And it's stock, unfortunately. There is a very close tolerance to the two speeds. This makes jets built using this engine considerably more maneuverable. Why that? The Kerbal Space Program subreddit. Dedicated to the growth and advancement of amateur rocket scientists! Planes in Space. 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. Thank you, I was able to reach up to 24km altitude with this design. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R.
