If you nudge your wing's angle up slightly with rotate tool then it'll move your prograde closer to your direction of flight and significantly reduce drag. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I don't have the numbers handy, but you can expect something like 400m/s at 15km. 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. 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?). As long as the engine gets enough air it will work at proper efficiency. This means it is better to have excessive amounts of oxygen than not to. The main body is a fuel tank with a Swivel engine at the end. Press J to jump to the feed. What are the altitudes for the various altitude record contracts? It was meant for low altitude flight. Very cool. 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. 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. Turbojets are so ridiculously efficient that it doesn't really matter. More air is better. You need to do it with what you've got. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. I didn't try for 20000m as it probably wouldn't do well. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit You can halve the drag by climbing a bit less than 3500m. 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. How do you get out of a corner when plotting yourself into a corner. What altitude and speed should I go? 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. You are just about at maximum speed and at the same time very close to stall speed. 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. I have enough patience to do the slow flying, but is it horribly inefficient? 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. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. With the tanks disconnected that way, the rockets don't leach from the jets. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. AoA and G-force moderation. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. Welcome to the forums. Can't remember where I saw/read about it - Scott Manley maybe? Don't be too surprised if KSP's aero model breaks down in edge cases. If it's below the cross-hairs, you need a little more AoA. I've added more engines, more intakes to no avail. Please consider starting a new thread rather than reviving this one. I don't have that cockpit in my career game yet, but maybe it will work with the other one. Why is there a voltage on my HDMI and coaxial cables? Imagine that first plane but with the bubble cockpit and the old style round intakes. How do I install mods for Kerbal Space Program 1.1? Your link has been automatically embedded. CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General Dedicated to the growth and advancement of amateur rocket scientists! Sideslip handling. The maximum cruise altitude is just over 40,000 feet. 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. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? Isn't that backwards snark? At that point your engines will be running about .7-.8 efficiency and you will be out of the thicker atmo which will allow you to go faster. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 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. Yes. Most SSTO space planes would be able to accomplish this easily. No, I think it's correct, unless I've got a brain fart going, here. Which is capable of high altitude, high speed flight. At altitude the nose goes up and down until it goes out of control. I was hoping that the new intakes would give it the added altitude. 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). This thread is quite old. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Display as a link instead, 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. Note that you need to activate the afterburner ("Wet Mode") manually. But my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. The benefits should be obvious.

I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Here's my example of dealing with the situation. Its an approximation missing someelements. lost birth certificate near berlin; ksp high altitude plane. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Will post my results. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). I would like to know which altitude I have to maintain for my experiments. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Display as a link instead, So that means that even if you are inside the atmosphere but still orbital (such as during aerobraking), your science will not count as "Inside the atmosphere", For example, orbiting Kerbin above 250km altitude, your science is counted as "In Space High over Kerbin." KSP also tends to have very harsh induced drag if angle of attack gets too high. Note: Your post will require moderator approval before it will be visible. (Actually, four ways: but balloons aren't in the stock game) Lifting surfaces are great but they lose effectiveness just as fast with altitude as drag falls. 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. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. The Panther engine can hold 19,000 steady and oscillates around 20,000. Build a plane or rocket for Kerbal high altitudes, We've added a "Necessary cookies only" option to the cookie consent popup, Screenshot of the Week #85 [Submissions Closed - Vote Now!]. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Learn more about Stack Overflow the company, and our products. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. As long a you can fly faster, the lower density at altitude can be compensated for. Let me. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. How do I align things in the following tabular environment? The best answers are voted up and rise to the top, Not the answer you're looking for? I start with the normal jet engines (which takes almost the complete runway). Don't rely on the efficiency indicator! When I say ", You know you've nailed it correctly if, when you're in level flight, your. Is anywhere a list of the altitude levels (I don't know a better term) available? Is there a single-word adjective for "having exceptionally strong moral principles"? principle. i dont know what kind of range youre looking for but i would make a significantly smaller plane. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Please consider starting a new thread rather than reviving this one. Build a plane or rocket for Kerbal high altitudes - Arqade If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. high-2 A Screenshot of Kerbal Space Program All trademarks are property of their respective owners in the US and other countries. 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). Highest and fastest possible is best. Delta-V is the velocity change necessary to perform orbital maneuvers. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. - but they were talking about having two intakes/engine. 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. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Beginner's Guide: Tips and Basics - Kerbal Space Program 2 Wiki Guide - IGN Basically I can hit a target altitude of 20,000m but can not maintain it. In addition to the traditional giant tube of explosions that flings things up high approach, Kerbal Space Program includes a very useful piece of equipment that became quite popular in the 20th century: wings.. This can make it a good alternative for when you want something that can be controllable and doesn't need excessive heat shielding, but still need to be able to go incredibly fast if necessary, at the expense of increased fuel consumption. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Your link has been automatically embedded. As said above, the Wheesley is specifically designed as a low altitude engine. This lowers their effective "weight"-- for example, a craft flying at 1400 m/s on Kerbin is effectively flying as if gravity were only 2/3 of its actual value.
