June 3, 2022 . Your previous content has been restored. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. Personally, I don't enjoy survey contracts on Kerbin. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Press question mark to learn the rest of the keyboard shortcuts. Why do many companies reject expired SSL certificates as bugs in bug bounties? - "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. 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)? I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. At about 400-500m/s (~15km), the two engines are even. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. 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). Your link has been automatically embedded. Fighting oscillations. 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 cannot paste images directly. with a thrust vectoring range of only 3 degrees. You are simply running out of atmosphere (i.e. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Is anywhere a list of the altitude levels (I don't know a better term) available? Building a High Altitude Jet | Stream pt. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. This is my current best hi alt plane. You may be correct and that 3 engine plane is a lemon. The other one I stay around 6000 meters. The easiest "default" way to build a plane in KSP-- i.e. And it's stock, unfortunately. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. 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. If it's above the cross-hairs, you need a little less. 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. Very cool. You can post now and register later. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

"Whiplash" Turbojet. 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. There is a very close tolerance to the two speeds. 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. Is it even possible? This means it is better to have excessive amounts of oxygen than not to. 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. With only panthers unlocked I might add. i dont know what kind of range youre looking for but i would make a significantly smaller plane. 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. Are you using Stock or NEAR/FAR? That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. It may work with stock too, I just don't know. I don't have that cockpit in my career game yet, but maybe it will work with the other one. Don't worry about Isp. First is thrust; the higher you get, the lower the thrust your engines deliver. You arent doing anything wrong. 2022 Take-Two Interactive Software, Inc. 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. That's because wings need to have some AoA to the airstream in order to generate much lift.

Listen to this guy, don't go much farther above 15000 with high altitude engines. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Kerbal Space Program 2 . The flight time won't be as long, but you'll be able to fly a "plane" above 18km. 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?). How can I make money in the new career mode? I wasn't expecting so many excellent answers! . Which is capable of high altitude, high speed flight. But. Thats my problem right now. Pvt. Ok, the panther engine is still not good enough. You cannot paste images directly. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Pasted as rich text. 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. When I say ", You know you've nailed it correctly if, when you're in level flight, your. Chapter 4. Only the fuel tanks attached to rockets have any oxidiser in them. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. 2022 Take-Two Interactive Software, Inc. KSP also tends to have very harsh induced drag if angle of attack gets too high. Paste as plain text instead, Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. 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. 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. 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. Originally posted by lord bird: yep thats right jool has a surface. If you have an account, sign in now to post with your account. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. The most efficient way is, of course, to make a high altitude (or space) plane. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Which lets you go faster, which lets you climb higher. You are just about at maximum speed and at the same time very close to stall speed. You can halve the drag by climbing a bit less than 3500m. Upload or insert images from URL. How can this new ban on drag possibly be considered constitutional? Ideally, you'll want to avoid these contracts until you get the High-Altitude Flight tech node and the improved jet engine that comes with it. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Upload or insert images from URL. 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. I don't have that other stuff yet. Arqade is a question and answer site for passionate videogamers on all platforms. jet engine efficiency in this game is based on built in thrust curves. Can't remember where I saw/read about it - Scott Manley maybe? 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). 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? The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. 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. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. These are the building blocks of solid spaceplane design!Subscribe!
