It only takes a minute to sign up. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. When I say ", You know you've nailed it correctly if, when you're in level flight, your. Which lets you go faster, which lets you climb higher. 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. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. even stranger is that the surface is textured. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Stoober AK 3.32K subscribers Subscribe 21K views 8 years ago This tutorial will cover designing and flying a plane that can soar. This causes the body of your plane to generate additional drag. I didn't try for 20000m as it probably wouldn't do well. Display as a link instead, It is somewhat slow but very steady in flight. I followed a similar strategy. high-2 A Screenshot of Kerbal Space Program Your previous content has been restored. I wasn't expecting so many excellent answers! Please consider starting a new thread rather than reviving this one. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. 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 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. Welcome to the forums, ZDW. As long as the engine gets enough air it will work at proper efficiency. What are the units of measure used in Kerbal Space Program? Of course, this thing has very limited range, speed and acceleration because of the extra weight. Please consider starting a new thread rather than reviving this one. air) that high up. The longest flight got them down to a little more than half full. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Your link has been automatically embedded. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Watch out for your SAS if you're running batteries without a jet for a long time. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. 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. 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? To reach the initial low Earth orbit of the International Space Stationof 300 km (now 400 km), the delta-v is over six times higher, about 9.4 km/s. You are simply running out of atmosphere (i.e. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. There are two factors to that: how thick the air is, how fast the ship is going. 1 Pod outside the level 3 VAB. 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?). Let me. That's all true, but just read the OP: hypersonic appears to be completely out of the question. (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. Something that I think has become less clear since someone updated the wiki. 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. 20 votes, 21 comments. Clear editor. Which is capable of high altitude, high speed flight. Don't be too surprised if KSP's aero model breaks down in edge cases. Create an account to follow your favorite communities and start taking part in conversations. 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. EDIT: Didn't notice you were using FAR. Basically you just need to fiddle with it and try some test flights. I don't have that cockpit in my career game yet, but maybe it will work with the other one. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Note: Your post will require moderator approval before it will be visible. Fighting oscillations. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. General Electric F-404 Afterburning Turbofan, Stratus-V Cylindrified Monopropellant Tank, Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine, LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine, T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine, S1 SRB-KD25k "Kickback" Solid Fuel Booster, IX-6315 "Dawn" Electric Propulsion System, AE-FF1 Airstream Protective Shell (1.25m), AE-FF3 Airstream Protective Shell (3.75m), PB-NUK Radioisotope Thermoelectric Generator, https://wiki.kerbalspaceprogram.com/index.php?title=J-404_%22Panther%22_Afterburning_Turbofan&oldid=95515. 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. 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. How can this new ban on drag possibly be considered constitutional? The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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!]. Evidence. Simply changing the intakes made it fly completely out of control and impossible to land. TLDR: You need parts you don't have to make a plane that flies that high. *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. If you have an account, sign in now to post with your account. 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. At about 400-500m/s (~15km), the two engines are even. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). 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. - Spamming airintakes didn't help. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. What am I doing wrong here in the PlotLegends specification. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. Aircraft can be very temperamental to fly, especially on the keyboard. Make sure you have lots of control surfaces because at very high in the atmosphere, there's not much air for the wings to control the craft with. At that point your engines will be running about .7-.8 efficiency and you will be out of the thicker atmo which will allow you to go faster. Only the fuel tanks attached to rockets have any oxidiser in them. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. 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. What are the altitudes for the various altitude record contracts? This page was last edited on 22 December 2019, at 20:54. But you'll need to unlock: High Altitude Flight Which cost 300 science. Yes, although they have only been flown with nearly full tanks. To get higher with the low tech jet engines, you need rocket assist. Here's Mr. Manley using it in his tutorial: @Pvt.Grichmann: I think it's at specific locations on Kerbin, not just anywhere above 18km. Yes. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. 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 What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. : : . 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. a screenshot of kerbal space program 2. by: lord bird. 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. Kerbal Space Program 2 . In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". http://kerbalspaceprogram.com, Press J to jump to the feed. Your previous content has been restored. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Reddit and its partners use cookies and similar technologies to provide you with a better experience. You cannot paste images directly. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Why do many companies reject expired SSL certificates as bugs in bug bounties? I generally don't fuss with AoI unless I'm making a long range cruiser. 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. New comments cannot be posted and votes cannot be cast. Do plugins for Kerbal Space Program work on unix? That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Is it correct to use "the" before "materials used in making buildings are"? If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). As said above, the Wheesley is specifically designed as a low altitude engine. Then it is "In Space Low over Mun.". Clear editor. 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). This means it is better to have excessive amounts of oxygen than not to. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Range with this method is pretty short due to drag. Most SSTO space planes would be able to accomplish this easily. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). It's Kerbal Space Program v.22! I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. How do you get out of a corner when plotting yourself into a corner. 2.) Dedicated to the growth and advancement of amateur rocket scientists! Cheers again fellas. You can go above 20km with the J-404 Panther. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Double your speed, you need twice as much fuel. 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. So the faster you go the higher you can fly where there is less drag. 2022 Take-Two Interactive Software, Inc. You can halve the drag by climbing a bit less than 3500m. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. Any of my search term words; All of my search term words; Find results in. Because when your engine has to take in air forcefully it automatically means there isn't enough surrounding your engine and that again means that air density and therefor air resistance must be pretty low too. 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. Isn't that backwards snark? More air is better. 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. 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 Highest and fastest possible is best. 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. You cannot paste images directly. Yes. These are the building blocks of solid spaceplane design!Subscribe! I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. With only panthers unlocked I might add. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Welcome to the forums. 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. If you have an account, sign in now to post with your account. A temple in the desert (6 29 47 S 141 40 3 W) known as Tut-Un Jeb-Ahn, although this name can only be seen when a vessel crashes into it. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. No, I think it's correct, unless I've got a brain fart going, here. Turbojets are so ridiculously efficient that it doesn't really matter. 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. 1.) If it's below the cross-hairs, you need a little more AoA. Is there a single-word adjective for "having exceptionally strong moral principles"? Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. 2022 Take-Two Interactive Software, Inc. 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." You could try combining the two. surface of jool. i dont know what kind of range youre looking for but i would make a significantly smaller plane. The Panther engine can hold 19,000 steady and oscillates around 20,000. Imagine that first plane but with the bubble cockpit and the old style round intakes. But you'll need to unlock: Which cost 300 science. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. With the tanks disconnected that way, the rockets don't leach from the jets. 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 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. You may be correct and that 3 engine plane is a lemon. jet engine efficiency in this game is based on built in thrust curves. The most efficient way is, of course, to make a high altitude (or space) plane. I should perhaps start trying out NEAR to get ready of 0.90, though. But maybe your patience? Since turbos are almost always enough to get you off the ground and up to altitude, I usually just do straight turbojets (with some RAPIERs for SSTO spaceplanes); the minute amount of fuel saved during the ascent isn't worth lugging those superfluous engines around at the hypersonic regime. Powered by Invision Community. Clear editor. The U-2 is probably the highest altitude aircraft still flying. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Jets drop thrust at higher altitude and speed, but also drop . 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. What altitude and speed should I go?
