Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. But. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Is it even possible? Should i add a larger wing area for higher lift? Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. I checked the wiki before I wrote my question, it seems I overread this paragraph Something that I think has become less clear since someone updated the wiki.

Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. Arqade is a question and answer site for passionate videogamers on all platforms. I wasn't expecting so many excellent answers! But maybe your patience? alternatively, combine a liquid fuel rocket into your plane. Thanks. For all your gaming related, space exploration needs. 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). Yes. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. The Panther engine can hold 19,000 steady and oscillates around 20,000. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. I'm trying to build a high altitude plane and have found out that the rules are different. That annoys me but I can't seem to get a design to make it work. 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. How do I install mods for Kerbal Space Program 1.1? How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Do plugins for Kerbal Space Program work on unix? This works, but it's not optimal. 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. Pasted as rich text. Put a couple of radial mount parachutes just above the com and add a reaction wheel.

Double your speed, you need twice as much fuel. even stranger is that the surface is textured. It was meant for low altitude flight. Simply changing the intakes made it fly completely out of control and impossible to land. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Building a High Altitude Jet | Stream pt. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. I decided to look into that two intakes thing, and it turns out to make 11-12 m/s difference at 19,000m with my plane. My question is really about controllability. However, I've failed to build a vehicle to achieve this (without a hundred retries). Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? I start with the normal jet engines (which takes almost the complete runway). 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 idea is to slow the plane to a stall above your landing spot the pop the parachute. You can post now and register later. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. 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. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. 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. Unfortunately, there's no simple rule to tell you what the angle needs to be when you're building the plane-- it depends on lots of variables, such as your weight, drag, intended cruising altitude, intended cruising speed. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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. All other versions are slower and lower and unstable in turns. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). 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. 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. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. 2022 Take-Two Interactive Software, Inc. Why that? Incidentally, for these speeds and altitudes, ordinary jets are the better choice. 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. (the engines will use very little at high altitude anyway). Welcome to the forums, ZDW. 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.

The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. 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. 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. principle. You'll notice that usually your prograde marker is slightly below your pitch. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. It only takes a minute to sign up. ksp high altitude plane. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

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. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Watch out for your SAS if you're running batteries without a jet for a long time. Kerbal Space Program 2 . Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Air temperatures vary with latitude and time of day. Planes in Space. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. The benefits should be obvious. Clear editor.
