Mounting a time-limited rescue mission for kerbal inbound to Kerbin. In this case lots of fuel is the wrong approach, I can get more than half way around Kerbin on 2 cans of Jet Fuel and a turbojet if I glide most of it. It was meant for low altitude flight. 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. At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing. But you'll need to unlock: High Altitude Flight Which cost 300 science. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. 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. Kerbal Space Program Jool Landing Youtube. Learn more about Stack Overflow the company, and our products. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Aircraft can be very temperamental to fly, especially on the keyboard. Sideslip handling. Thanks. There is a very close tolerance to the two speeds. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. Listen to this guy, don't go much farther above 15000 with high altitude engines. You can post now and register later. It may work with stock too, I just don't know. 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 There's basically three ways to do that: lifting surfaces, thrust, and orbiting. 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. @SaintWacko's advice is probably the most practical. (the engines will use very little at high altitude anyway). Turbojets are so ridiculously efficient that it doesn't really matter. Orbiting is the most fun one: the higher the orbit, the less speed you need to maintain to stay in orbit, *and* the less air there is, so that's a double-whammy in terms of reducing fuel consumption. Is anywhere a list of the altitude levels (I don't know a better term) available? Will post my results. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. This page was last edited on 22 December 2019, at 20:54. 2022 Take-Two Interactive Software, Inc. 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. 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). Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. Most SSTO space planes would be able to accomplish this easily. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Thanks for asking this, I've been struggling with the same problem in career mode. You'll notice that usually your prograde marker is slightly below your pitch. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Have you checked out the wiki yet?

Visit Stack Exchange air) that high up. Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. This is my current best hi alt plane. 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. You can post now and register later. 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. Highest and fastest possible is best. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. - Insane TWR didn't help. You cannot paste images directly. When you are surrounded by plenty of air there will of course be no need to suck in air artificially but the higher you get the less dense the air around you becomes and in order to make sure that your engines have enough oxygen to burn the fuel it needs to suck air in forcefully. Is there a single-word adjective for "having exceptionally strong moral principles"? It will be expensive and time consuming. Paste as plain text instead, 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. 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. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Whiplash is the engine you would want to use on a plane meant to go 20km. Only the fuel tanks attached to rockets have any oxidiser in them. Simply changing the intakes made it fly completely out of control and impossible to land. Why that? High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. 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. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. lost birth certificate near berlin; ksp high altitude plane. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Powered by Invision Community. As has been said, ISP is nothing to worry about. I was hoping that the new intakes would give it the added altitude. Note: Your post will require moderator approval before it will be visible. 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). Clear editor. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. Then it is "In Space Low over Mun.". The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. - Spamming airintakes didn't help. You arent doing anything wrong. How do I align things in the following tabular environment? 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. Yes. Slap that behind a plane you'll be able to go beyond 20km without any trouble. 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. Information Changelog Stats What am I doing wrong here in the PlotLegends specification. http://kerbalspaceprogram.com, Press J to jump to the feed. 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? Are you using Stock or NEAR/FAR? In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". 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. 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. 2022 Take-Two Interactive Software, Inc. You cannot paste images directly. Please consider starting a new thread rather than reviving this one. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. I generally don't fuss with AoI unless I'm making a long range cruiser. As long as the engine gets enough air it will work at proper efficiency. You may be correct and that 3 engine plane is a lemon. Let me share what I know about jet engines, speed, and efficiency.

Very cool. Don't be too surprised if KSP's aero model breaks down in edge cases. Building a High Altitude Jet | Stream pt. 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. jet engine efficiency in this game is based on built in thrust curves. . Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. This works, but it's not optimal. - Insane lift to weight didn't help. There are two factors to that: how thick the air is, how fast the ship is going. - but they were talking about having two intakes/engine. Which is capable of high altitude, high speed flight. The SR-71 could probably fly higher, but it isn't flying any more. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Press J to jump to the feed.

I should perhaps start trying out NEAR to get ready of 0.90, though. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. 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. Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude. If it's above the cross-hairs, you need a little less. I also added a parachute and decoupler since I find it too hard to correctly land this thing yet ;-) I managed to land in the water once, though.

They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Cookie Notice Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. 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. All trademarks are property of their respective owners in the US and other countries. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Display as a link instead, 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. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Please consider starting a new thread rather than reviving this one. Here's my example of dealing with the situation. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. So the faster you go the higher you can fly where there is less drag. 600+ m/s) and low altitudes (e.g. You are just about at maximum speed and at the same time very close to stall speed. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. 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 most efficient way is, of course, to make a high altitude (or space) plane. I followed a similar strategy. The maximum cruise altitude is just over 40,000 feet. Delta-V is the velocity change necessary to perform orbital maneuvers. This means it is better to have excessive amounts of oxygen than not to. Personally, I don't enjoy survey contracts on Kerbin. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ How can I make money in the new career mode? If it's below the cross-hairs, you need a little more AoA. Arqade is a question and answer site for passionate videogamers on all platforms. 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. The returns are diminishing so eventually you will hit a ceiling. Trying to do something without the right part is long and difficult path. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). How to tell which packages are held back due to phased updates. Planes in Space. The U-2 is probably the highest altitude aircraft still flying. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. All other versions are slower and lower and unstable in turns. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. 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. - "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. Typically, I watch my Apoapsis as I boost to the high altitude, and there's enough momentum to coast to the peak before completely running out of fuel. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. I've added more engines, more intakes to no avail. First is thrust; the higher you get, the lower the thrust your engines deliver. Anyway thanks in advance. These designs are great for getting around Kerbin quickly, but without going orbital. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. But you'll need to unlock: Which cost 300 science. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Isn't that backwards snark? Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. even stranger is that the surface is textured. 20 votes, 21 comments. You can do that by right-clicking the engine and clicking "Toggle Mode." I've been finding it difficult to build a jet that can fly over 15km alt. It is somewhat slow but very steady in flight.
