KSP also tends to have very harsh induced drag if angle of attack gets too high. You'll notice that usually your prograde marker is slightly below your pitch. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. 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. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. 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). 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. 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. Or you need to put a little bit of angle of incidence in your wings, which will reduce drag since you don't have to pitch the entire plane up, but will be stuck at a fixed angle meaning you'll have to pitch up or down anyway during certain phases of the flight that the plane isn't optimised for. 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. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . 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. 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. Turbojets are so ridiculously efficient that it doesn't really matter. For all your gaming related, space exploration needs. I start with the normal jet engines (which takes almost the complete runway). Let me. If it's below the cross-hairs, you need a little more AoA. You need to do it with what you've got. Why is there a voltage on my HDMI and coaxial cables? 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. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. 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. My question is really about controllability. If it's above the cross-hairs, you need a little less. If it's below the cross-hairs, you need a little more AoA. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. So Pvt. Now I have a plane that will fly around the world at an altitude of the low-20s. Put a couple of radial mount parachutes just above the com and add a reaction wheel.

The most efficient way is, of course, to make a high altitude (or space) plane. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. You can post now and register later. 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. Evidence. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable.

I recommend using a solid rocket booster (or 2 or 5) to you get you the altitude and then launch a small rocket powered plane. 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. The Kerbal Space Program subreddit. What are the minimum altitudes for each warp level? Thats my problem right now. a screenshot of kerbal space program 2. by: lord bird. and our Press question mark to learn the rest of the keyboard shortcuts. Which is capable of high altitude, high speed flight. That will unlock: But since when do Kerbals wait for ideal conditions? 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. 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. Hopefully this will be helpful to you. jet engine efficiency in this game is based on built in thrust curves. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Thanks for asking this, I've been struggling with the same problem in career mode. If it's above the cross-hairs, you need a little less. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Welcome to the forums, ZDW. Or try using SRBs instead. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Simply changing the intakes made it fly completely out of control and impossible to land. Your link has been automatically embedded. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. air) that high up. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. 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. Upload or insert images from URL. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. New comments cannot be posted and votes cannot be cast. The U-2's published maximum altitude is somewhere above 74,000 feet. 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? Do plugins for Kerbal Space Program work on unix? 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. 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. Content titles and body; Content titles only Slap that behind a plane you'll be able to go beyond 20km without any trouble. You could try combining the two. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. Can't remember where I saw/read about it - Scott Manley maybe? How do I align things in the following tabular environment? First is thrust; the higher you get, the lower the thrust your engines deliver. Or is it the same for all celestial bodies? surface of jool. 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). 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. Display as a link instead, For more information, please see our 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. I didn't try for 20000m as it probably wouldn't do well. But you'll need to unlock: Which cost 300 science. If you've attached them to your fuselage with zero AoA, what that means is that when you fly, you're going to have to have the entire plane pitched slightly above in order to generate lift. These are the building blocks of solid spaceplane design!Subscribe! Pasted as rich text. You cannot paste images directly. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. You arent doing anything wrong. even stranger is that the surface is textured. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. 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. I've added more engines, more intakes to no avail. When I say ", You know you've nailed it correctly if, when you're in level flight, your. 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?). Cookie Notice 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. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). So the faster you go the higher you can fly where there is less drag. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. 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. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. With the tanks disconnected that way, the rockets don't leach from the jets. Thanks. 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. 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. I generally don't fuss with AoI unless I'm making a long range cruiser. A destructible memorial to the old Mk. 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. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Is it possible to get to an altitude of 16-20km with normal plane engines? Watch out for your SAS if you're running batteries without a jet for a long time. lost birth certificate near berlin; ksp high altitude plane. It is somewhat slow but very steady in flight. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. The benefits should be obvious. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Privacy Policy. But maybe your patience? Is there a single-word adjective for "having exceptionally strong moral principles"? And how many km can I expect to get per v (as calculated by Engineer redux Kerbin atmospheric stats, I know this is weird with planes)? The SR-71 could probably fly higher, but it isn't flying any more. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

But a rockets can do it. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. It will be expensive and time consuming. Listen to this guy, don't go much farther above 15000 with high altitude engines. Paste as plain text instead, I'd almost expect it to work better in stock since infini-gliders can be done. 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. However, I've failed to build a vehicle to achieve this (without a hundred retries). Why do many companies reject expired SSL certificates as bugs in bug bounties? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Welcome to the forums. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. You are simply running out of atmosphere (i.e. How to tell which packages are held back due to phased updates. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Note that keeping the plane weight low is critical, only carry a very small amount of fuel.
