Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. That annoys me but I can't seem to get a design to make it work. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman.
[Solved] 30 20 / Double your speed, you need twice as much fuel. AoA and G-force moderation.
high altitude flight :: Kerbal Space Program General Discussions But maybe your patience? What are the units of measure used in Kerbal Space Program? Yes, although they have only been flown with nearly full tanks.
Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) Your link has been automatically embedded. 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?). 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? Which is capable of high altitude, high speed flight. The SR-71 could probably fly higher, but it isn't flying any more. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. 1.) 20 votes, 21 comments. I don't have the numbers handy, but you can expect something like 400m/s at 15km. and our If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. If it's above the cross-hairs, you need a little less. even stranger is that the surface is textured. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. (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. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). 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. Will post my results. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Planes in Space. 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). Note: Your post will require moderator approval before it will be visible. You cannot paste images directly. Building a High Altitude Jet | Stream pt. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Ok, the panther engine is still not good enough. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Display as a link instead, 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. Main goals: Auto-trimming. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift.
Airplane Plus on SpaceDock Very cool. You are just about at maximum speed and at the same time very close to stall speed. What am I doing wrong here in the PlotLegends specification. 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. Press J to jump to the feed. 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. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range.
KSP Career: Episode 13 - High Altitude Surveys - YouTube The main body is a fuel tank with a Swivel engine at the end. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. 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. Dedicated to the growth and advancement of amateur rocket scientists! 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. 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. 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. Powered by Invision Community. Pasted as rich text. alternatively, combine a liquid fuel rocket into your plane. Connect and share knowledge within a single location that is structured and easy to search. This thread is quite old. Let me share what I know about jet engines, speed, and efficiency.
How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit But a rockets can do it.
Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Thats my problem right now. Arqade is a question and answer site for passionate videogamers on all platforms. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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. - Insane lift to weight didn't help. As I understand, the OP wanted "the most efficient way to fly", and simply needed a bit of help in realizing that that is a hypersonic, high-altitude, high-performance aircraft which is a RAPIER and a little oxidizer away from being an SSTO spaceplane. Your previous content has been restored.
I'm in career mode and got all groups of the 45-science-cost level, except Flight Control, and additionally have Electrics, Heavy Rocketry and Fuel Systems.
KSP - High Altitude Aircraft - YouTube Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. New comments cannot be posted and votes cannot be cast. Fighting oscillations. 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. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. 3x06: I design a new, high altitude, jet to collect high atmospheric science. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Information Changelog Stats Note that keeping the plane weight low is critical, only carry a very small amount of fuel. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. 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. What altitude and speed should I go? This is the first version. A destructible memorial to the old Mk. Highest and fastest possible is best. KSP Career: Episode 13 - High Altitude Surveys Mike Aben 28.5K subscribers Subscribe 7.7K views 7 years ago Day 114: A busy day at the KSC with three missions, the highlights being the launch. Pvt. air) that high up. Thanks for the help! Don't rely on the efficiency indicator!
The U-2's published maximum altitude is somewhere above 74,000 feet. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Is it even possible? I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. But you'll need to unlock: Which cost 300 science. Welcome to the forums. Even up there the plane acts squirrely. 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. 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. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel.
Spaceplane - Wikipedia This thread is quite old. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. 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. Pasted as rich text.
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. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. I don't have that other stuff yet. Display as a link instead,
ksp high altitude plane - digitalidentityorganization.com A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 600+ m/s) and low altitudes (e.g. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. It's Kerbal Space Program v.22! Clear editor. But you'll need to unlock: High Altitude Flight Which cost 300 science. 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. If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. Or about the same speed but 1000 m higher. edited 6 yr. ago.
Please consider starting a new thread rather than reviving this one. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. 2022 Take-Two Interactive Software, Inc. It only takes a minute to sign up.

Does a plane consume more fuel if it flies at higher altitudes? Slap that behind a plane you'll be able to go beyond 20km without any trouble. This tutorial will cover designing and flying a plane that can soar at high altitudes! 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 altitude the nose goes up and down until it goes out of control. Simply changing the intakes made it fly completely out of control and impossible to land. 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!]. 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). But. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. 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). Upload or insert images from URL. It flames out at 25,000. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. : : . So the faster you go the higher you can fly where there is less drag. 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.

With the tanks disconnected that way, the rockets don't leach from the jets. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? These are the building blocks of solid spaceplane design!Subscribe! There are no requirements as far as size or power are concerned, as the AI Pilot is capable of flying pretty much anything - from tiny scout planes to oversized freight craft. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Why is there a voltage on my HDMI and coaxial cables?
