At about 400-500m/s (~15km), the two engines are even. Kerbal Space Program Jool Landing Youtube. Do plugins for Kerbal Space Program work on unix? The most efficient way is, of course, to make a high altitude (or space) plane. Exorcet's Content - Kerbal Space Program Forums How can I make money in the new career mode? 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. 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. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. With only panthers unlocked I might add. Kerbin | Kerbal Space Program Wiki | Fandom So I've created those two planes, both with weasley turbofan engine: This is your problem-- as folks have pointed out, it's not a high-altitude engine. Your link has been automatically embedded. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Thats my problem right now. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. rev2023.3.3.43278. Either of the two speeds are to be avoided. Watch out for your SAS if you're running batteries without a jet for a long time. 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. 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. Pvt. This means it is better to have excessive amounts of oxygen than not to. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. Paste as plain text instead, 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. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. If you have an account, sign in now to post with your account. high-2 A Screenshot of Kerbal Space Program If released at a speed of 700 or more m/s and an altitude of 20 or more km, the satellite will achieve orbit with its second stage mostly full, leaving it with approximately 1600 m/s of delta-V -- enough to achieve lunar or interplanetary orbits and, on small bodies, landings. Proceed with caution. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. A little while back I spent a long time trying to circumnavigate Kerbin on the least liquid fuel possible (i posted the record to the sub: 254 units of fuel. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Please consider starting a new thread rather than reviving this one. You can halve the drag by climbing a bit less than 3500m. Is anywhere a list of the altitude levels (I don't know a better term) available? Note: Your post will require moderator approval before it will be visible. Powered by Invision Community. 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. 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. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. As has been said, ISP is nothing to worry about. I don't have the numbers handy, but you can expect something like 400m/s at 15km. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". 2022 Take-Two Interactive Software, Inc. 3.) - Insane TWR didn't help. What are the units of measure used in Kerbal Space Program? Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Or about the same speed but 1000 m higher. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Rockets aren t the only way to get to space. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. 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. Simply changing the intakes made it fly completely out of control and impossible to land. 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). That annoys me but I can't seem to get a design to make it work. Does a plane consume more fuel if it flies at higher altitudes? You will find that when you're flying around, will always be slightly below the crosshairs on the navball. If you have an account, sign in now to post with your account. A destructible memorial to the old Mk. 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. Of course, this thing has very limited range, speed and acceleration because of the extra weight. Thank you, I was able to reach up to 24km altitude with this design. 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. 3x06: I design a new, high altitude, jet to collect high. Building a High Altitude Jet | Stream pt. Things that work at low altitude don't work so well up high and the plane ends up going up and down while slowly losing speed until it can't maintain altitude anymore. lost birth certificate near berlin; ksp high altitude plane. Aircraft can be very temperamental to fly, especially on the keyboard. 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. ksp high altitude plane. 600+ m/s) and low altitudes (e.g. Will post my results. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. There is a very close tolerance to the two speeds. Only the fuel tanks attached to rockets have any oxidiser in them. You cannot paste images directly. EDIT: Didn't notice you were using FAR. Display as a link instead, 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. Sideslip handling. Planes in Space. Any of my search term words; All of my search term words; Find results in. Display as a link instead, Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. If not, please explain why, which I know you have no problem doing! High altitude planes - Kerbal Space Program Forums High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. By climbing, you reduce drag, exponentially with altitude. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Double your speed, you need twice as much fuel. TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki FBW uses three controllers - pitch, roll and yaw. 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. Don't worry about Isp. My question is really about controllability. Laythe - Kerbal Space Program Wiki How do you get out of a corner when plotting yourself into a corner. I followed a similar strategy. Isn't that backwards snark? How do I align things in the following tabular environment? 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. 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? You cannot paste images directly. What determines the maximum altitude a plane can reach? KSP Career: Episode 13 - High Altitude Surveys - YouTube What altitude and speed should I go? 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. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. So Pvt. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Please consider starting a new thread rather than reviving this one. But since when do Kerbals wait for ideal conditions? But maybe your patience? It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Valve Corporation. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. KSP - High Altitude Aircraft - YouTube The best answers are voted up and rise to the top, Not the answer you're looking for? The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Using Kolmogorov complexity to measure difficulty of problems? Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. The Panther engine can hold 19,000 steady and oscillates around 20,000. If it's below the cross-hairs, you need a little more AoA. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). (the engines will use very little at high altitude anyway). There are no requirements as far as size or power are concerned, as the AI Pilot is capable of flying pretty much anything - from tiny scout planes to oversized freight craft. Yes. Slap that behind a plane you'll be able to go beyond 20km without any trouble. KSP also tends to have very harsh induced drag if angle of attack gets too high. Here's my example of dealing with the situation. What am I doing wrong here in the PlotLegends specification. Hello there. 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. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Welcome to the forums, ZDW. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. So if you want to make a plane go as fast as possible, you want to minimise both angle of attack and angle of incidence necessary to sustain level flight at your target speed and altitude. edited 6 yr. ago. Press question mark to learn the rest of the keyboard shortcuts. It flames out at 25,000. Let me share what I know about jet engines, speed, and efficiency. - "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. Why that? Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. The U-2's published maximum altitude is somewhere above 74,000 feet. 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. 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. To get higher with the low tech jet engines, you need rocket assist. Your previous content has been restored. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. 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. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. 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. 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. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. That's all true, but just read the OP: hypersonic appears to be completely out of the question. Let me. Create an account to follow your favorite communities and start taking part in conversations. 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. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Unfortunately, there's no simple rule to tell you what the angle needs to be when you're building the plane-- it depends on lots of variables, such as your weight, drag, intended cruising altitude, intended cruising speed. However, it seems as if your delta wing has has more area, might that be it? 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. principle. You need to do it with what you've got. Satellite Launcher - Kerbal Space Program Wiki As long a you can fly faster, the lower density at altitude can be compensated for. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. No, I think it's correct, unless I've got a brain fart going, here. June 3, 2022 . The longest flight got them down to a little more than half full. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Why not keep the engine for multi-stage rockets? - Space Exploration Planes and Altitude differences. :: Kerbal Space Program General Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. Basically you just need to fiddle with it and try some test flights. These designs are great for getting around Kerbin quickly, but without going orbital. and our Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. It is somewhat slow but very steady in flight. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Jets drop thrust at higher altitude and speed, but also drop . 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. 2022 Take-Two Interactive Software, Inc. 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. Most SSTO space planes would be able to accomplish this easily. 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. The main body is a fuel tank with a Swivel engine at the end. If it's above the cross-hairs, you need a little less.
