Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . 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 Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. With only panthers unlocked I might add. 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. First is thrust; the higher you get, the lower the thrust your engines deliver. (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. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Do plugins for Kerbal Space Program work on unix? ksp high altitude plane. What are the units of measure used in Kerbal Space Program? Note that keeping the plane weight low is critical, only carry a very small amount of fuel. 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. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. This causes the body of your plane to generate additional drag. Is anywhere a list of the altitude levels (I don't know a better term) available? FBW uses three controllers - pitch, roll and yaw. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. This makes jets built using this engine considerably more maneuverable. The benefits should be obvious. I'm going to try adding a small solid fuel rocket engine toned down to get the initial height then dump it, as well as check into that high end gear mentioned. Its an approximation missing someelements. At about 400-500m/s (~15km), the two engines are even. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Most SSTO space planes would be able to accomplish this easily. Pasted as rich text. How can I make money in the new career mode? Is it suspicious or odd to stand by the gate of a GA airport watching the planes? That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. 2/3 (KSP 1.11.2) - YouTube I break out the Mk2 parts and Panther engines to build a better jet that can go higher and faster. Subscribe -. 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. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Is it possible to get to an altitude of 16-20km with normal plane engines? 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. It is usually best for initial designs to be based on logic and real-world physics and then be prepared to experiment with non-logical alternatives for optimisation. It is somewhat slow but very steady in flight. Any advices for building a vehicle for this task? Building a High Altitude Jet | Stream pt. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. I was hoping that the new intakes would give it the added altitude. A jet engine from KSP 0.18 A jet engine is an air-breathing engine which uses onboard liquid fuel and combusts it with the oxygen drawn from the atmosphere. Don't be too surprised if KSP's aero model breaks down in edge cases. KSP also tends to have very harsh induced drag if angle of attack gets too high. You may be correct and that 3 engine plane is a lemon. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). Thanks for the help! Or is it the same for all celestial bodies? As you found out, it basically konks out at 15km. high-2 A Screenshot of Kerbal Space Program 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. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. Basically I can hit a target altitude of 20,000m but can not maintain it. The most efficient way is, of course, to make a high altitude (or space) plane. Please consider starting a new thread rather than reviving this one. 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. Are you using Stock or NEAR/FAR? I am currently designing a mission that will involve several very long distance plane flights. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. It flames out at 25,000. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. This can make it a good alternative for when you want something that can be controllable and doesn't need excessive heat shielding, but still need to be able to go incredibly fast if necessary, at the expense of increased fuel consumption. 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. As long as the engine gets enough air it will work at proper efficiency. Then it is "In Space Low over Mun.". So Pvt. Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane Do you know how many intakes/turbojet are needed to run in the regime you described? Clear editor. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. EDIT: Didn't notice you were using FAR. Hopefully this will be helpful to you. Simply changing the intakes made it fly completely out of control and impossible to land. Your answer got me in the right direction, though I ended up with a different design (see my own answer). If it's below the cross-hairs, you need a little more AoA. Display as a link instead, 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 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 . So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Third, which I haven't given a good try, would be a carefully-timed deorbit maneuver so you come down through your desired location as you fall from space. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 2022 Take-Two Interactive Software, Inc. 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. Pasted as rich text. 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. You could try combining the two. Planes in Space. That annoys me but I can't seem to get a design to make it work. What are the minimum altitudes for each warp level? From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. The thrust of jets (turbo or otherwise) depends on airspeed: basics deliver more thrust at low speeds, while turbojets only really come into their own when you fly very fast (which also means flying very high, 20km and over). All rights reserved. Don't worry about Isp. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Is it even possible? This tutorial will cover designing and flying a plane that can soar at high altitudes! edited 6 yr. ago. If it's above the cross-hairs, you need a little less. 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. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. The longest flight got them down to a little more than half full. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. - Spamming airintakes didn't help. 1 Pod outside the level 3 VAB. Using Kolmogorov complexity to measure difficulty of problems? : : . . If it's below the cross-hairs, you need a little more AoA. Upload or insert images from URL. That's because wings need to have some AoA to the airstream in order to generate much lift. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. 3.) Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. Rationale: 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 AoA at all on the wings. If you want to cover your aircraft with loads of intakes, I'm sure you could easily fly above 35km and reach 2000+ m/s velocity. If you have an account, sign in now to post with your account. Connect and share knowledge within a single location that is structured and easy to search. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Contents 1 Usage 2 Construction 3 Categories 3.1 Airplane 3.2 Seaplane 3.3 Spaceplane 3.4 VTOL 3.5 Glider 3.6 Mothership 4 Operation 4.1 Flight records 5 Notes Usage No, I think it's correct, unless I've got a brain fart going, here. The easiest "default" way to build a plane in KSP-- i.e. 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. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Listen to this guy, don't go much farther above 15000 with high altitude engines. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. 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. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight.

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. This thread is quite old. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. I've been finding it difficult to build a jet that can fly over 15km alt. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. The Kerbal Space Program subreddit. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Yes. Thats my problem right now. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology.
