Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. You need to do it with what you've got. Sub-orbital spaceflight - Wikipedia Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Press J to jump to the feed. Imagine that first plane but with the bubble cockpit and the old style round intakes. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! - "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 do small African island nations perform better than African continental nations, considering democracy and human development? Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). air) that high up. To avoid running out of fuel altogether, I have a second plane with small tanks (no oxidizer) attached directly to the jet engines, and the rockets attached behind the fuselage, which is entirely oxidized tanks. But since when do Kerbals wait for ideal conditions? Or about the same speed but 1000 m higher. First is thrust; the higher you get, the lower the thrust your engines deliver. Designing a High Altitude Jet | KSP: Making Space Home Mike Aben 24.8K subscribers Join Subscribe 85 Share 3.4K views 1 year ago Ep. This makes jets built using this engine considerably more maneuverable. Air temperatures vary with latitude and time of day. Designing a High Altitude Jet | KSP: Making Space Home In the stock atmosphere, the benefits of moving faster outweigh almost everything else. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. 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. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. But a rockets can do it. alternatively, combine a liquid fuel rocket into your plane. 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. How to know if you've nailed it perfectly: when you're cruising in level flight, you want the marker to be precisely centered in your navball cross-hairs. I would like to know which altitude I have to maintain for my experiments. Create an account to follow your favorite communities and start taking part in conversations. I have enough patience to do the slow flying, but is it horribly inefficient? a screenshot of kerbal space program 2. by: lord bird. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Thanks. You can post now and register later. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. 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. Isn't that backwards snark? Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. For all your gaming related, space exploration needs. 3x06: I design a new, high altitude, jet to collect high. Anyway thanks in advance. The U-2's published maximum altitude is somewhere above 74,000 feet. Display as a link instead, Kerbal Space Program 2 . 2.) KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate 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. 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. I should perhaps start trying out NEAR to get ready of 0.90, though. 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.. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. 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 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. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Ok, the panther engine is still not good enough. You cannot paste images directly. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Knowing how to design these types of planes make jumping in to SSTO design very easy as there are only a few minor changes that need to be made.Music Credits:1st Song: \"Elephants\" - YouTube Audio Library2nd Song: \"Hot Heat\" - YouTube Audio Library3rd Song: \"Echoes\" - Kasbo - https://soundcloud.com/k-sboWhat game is this? How do I align things in the following tabular environment? Is it possible to get to an altitude of 16-20km with normal plane engines? At 3500m, you have half the drag you'd have at the surface; at 7km, 1/4 the drag, at 10.5km, 1/8 the drag, etc. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. Grichman's answer got me in the right direction. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. Hopefully this will be helpful to you. Put a couple of radial mount parachutes just above the com and add a reaction wheel. 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. 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. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Trying to do something without the right part is long and difficult path. I wasn't expecting so many excellent answers! Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Welcome to the forums, ZDW. Double your speed, you need twice as much fuel. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. This is the first version. As long as the engine gets enough air it will work at proper efficiency. Your previous content has been restored. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Will post my results. Upload or insert images from URL. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Long distance airplane flight tips? - Kerbal Space Program Forums I don't have the numbers handy, but you can expect something like 400m/s at 15km. The best answers are voted up and rise to the top, Not the answer you're looking for? However, I've failed to build a vehicle to achieve this (without a hundred retries). The main body is a fuel tank with a Swivel engine at the end. You may be correct and that 3 engine plane is a lemon. Cheers again fellas. 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. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. First off as of .15.1 intakes don't do anything. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. 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. I'm trying to build a high altitude plane and have found out that the rules are different. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. This causes the body of your plane to generate additional drag. When I say ", You know you've nailed it correctly if, when you're in level flight, your. As has been said, ISP is nothing to worry about. Another approach, which I was managing with some success before I figured out jets, is to build a rocket and catapult yourself towards the measurement point. You'll notice that usually your prograde marker is slightly below your pitch. Or is it the same for all celestial bodies? 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. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Fighting oscillations. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . J-404 "Panther" Afterburning Turbofan - Kerbal Space Program Is there a single-word adjective for "having exceptionally strong moral principles"? ksp high altitude plane. However, it seems as if your delta wing has has more area, might that be it? Is it suspicious or odd to stand by the gate of a GA airport watching the planes? The most efficient way is, of course, to make a high altitude (or space) plane. TLDR: You need parts you don't have to make a plane that flies that high. I'd almost expect it to work better in stock since infini-gliders can be done. 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.
