A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Yes, although they have only been flown with nearly full tanks. 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. Range with this method is pretty short due to drag. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Have you checked out the wiki yet? Be sure to have enough intakes (I think maximum efficiency in stock is 1 ramjet intake per ~2 tons of plane, though that is aesthetically ridiculous), and if you're still running short of intake air, you can dip down a bit to speed up and get to denser air. Paste as plain text instead, Evidence. Content titles and body; Content titles only Any advices for building a vehicle for this task? How can I make money in the new career mode? The SR-71 could probably fly higher, but it isn't flying any more. Powered by Invision Community. Which lets you go faster, which lets you climb higher. I don't have the numbers handy, but you can expect something like 400m/s at 15km. The most efficient way is, of course, to make a high altitude (or space) plane. 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. edited 6 yr. ago. All other versions are slower and lower and unstable in turns. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). Display as a link instead, The high performance engine for me performs pretty good till about 15000 meter. One of my planes is small and agile, and can easily enough glide to a safe landing even if the rockets consume all the fuel. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Display as a link instead, You can post now and register later. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Clear editor. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. This tutorial will cover designing and flying a plane that can soar at high altitudes! 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). No, I think it's correct, unless I've got a brain fart going, here. It only takes a minute to sign up. 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 Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. 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. I would like to know which altitude I have to maintain for my experiments. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. It was meant for low altitude flight. It will be expensive and time consuming. How do I align things in the following tabular environment? 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. 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. Your answer got me in the right direction, though I ended up with a different design (see my own answer). i dont know what kind of range youre looking for but i would make a significantly smaller plane. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. As has been said, ISP is nothing to worry about. 20 votes, 21 comments. 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. I started by attaching two LV-909 rocket engines to a regular low-atmosphere plane: In this save, I don't have custom action groups yet, so I'm using the RCS control to toggle between jet and rocket modes. AoA and G-force moderation. Ok, the panther engine is still not good enough. How to tell which packages are held back due to phased updates. I've been finding it difficult to build a jet that can fly over 15km alt. Only the fuel tanks attached to rockets have any oxidiser in them. 3.) Any of my search term words; All of my search term words; Find results in. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. New comments cannot be posted and votes cannot be cast. Whiplash is the engine you would want to use on a plane meant to go 20km. Kerbal Space Program Jool Landing Youtube. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 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 . Ksp engine altitudes 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. Double your speed, you need twice as much fuel. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. You are simply running out of atmosphere (i.e. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. 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. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. Pasted as rich text. Your previous content has been restored. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. Chapter 4. I don't have any exact numbers for you, but you can right-click an engine in flight and it will show both current and optimal airflow, which should hopefully let you work out the best altitude. It's Kerbal Space Program v.22! Proceed with caution. When I say ", You know you've nailed it correctly if, when you're in level flight, your. I wasn't expecting so many excellent answers! But you'll need to unlock: Which cost 300 science. Thanks. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. As long a you can fly faster, the lower density at altitude can be compensated for. Welcome to the forums, ZDW. Challenges Most SSTO space planes would be able to accomplish this easily. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? 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. : : . Please consider starting a new thread rather than reviving this one. You can post now and register later. Let me. 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. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. 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 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 Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. But maybe your patience? The U-2 is probably the highest altitude aircraft still flying. You arent doing anything wrong. To get higher with the low tech jet engines, you need rocket assist. So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less. Cookie Notice Something that I think has become less clear since someone updated the wiki. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. 2022 Take-Two Interactive Software, Inc. Are you using Stock or NEAR/FAR? I also had problems with a high altitude plane until I decided to follow the K.I.S.S. @SaintWacko's advice is probably the most practical. Pvt. Is anywhere a list of the altitude levels (I don't know a better term) available? 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. Why that? 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). lost birth certificate near berlin; ksp high altitude plane. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Highest and fastest possible is best. If you have an account, sign in now to post with your account. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. 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. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). 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. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Why do many companies reject expired SSL certificates as bugs in bug bounties? From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. But since when do Kerbals wait for ideal conditions? What's the difference between a power rail and a signal line? Pasted as rich text. The U-2's published maximum altitude is somewhere above 74,000 feet. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. 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. It is somewhat slow but very steady in flight. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. 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. Anyway thanks in advance. This works, but it's not optimal. - Spamming airintakes didn't help.

Rockets aren t the only way to get to space. Press question mark to learn the rest of the keyboard shortcuts. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Espaol - Latinoamrica (Spanish - Latin America), https://steamcommunity.com/sharedfiles/filedetails/?id=1933948095, https://steamcommunity.com/sharedfiles/filedetails/?id=1933948668, https://steamcommunity.com/sharedfiles/filedetails/?id=1934517923, https://steamcommunity.com/sharedfiles/filedetails/?id=1335577943, https://steamcommunity.com/sharedfiles/filedetails/?id=1640213502, https://steamcommunity.com/sharedfiles/filedetails/?id=1640214586, https://steamcommunity.com/sharedfiles/filedetails/?id=1937826505, https://steamcommunity.com/sharedfiles/filedetails/?id=1937931692. 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. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Yes. How do I install mods for Kerbal Space Program 1.1? Don't rely on the efficiency indicator! *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. Upload or insert images from URL. If drag were the only concern, at any given altitude the slower you go, the less fuel you need: the work done by drag over a distance grows linearly with speed (the force grows quadratically with speed, but the time falls linearly).
