Jet engine - Kerbal Space Program Wiki Trying to do something without the right part is long and difficult path. Third, which I haven't given a good try, would be a carefully-timed deorbit maneuver so you come down through your desired location as you fall from space. I am currently designing a mission that will involve several very long distance plane flights. its rather flat but its a solid surface. 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. 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.. Powered by Invision Community. It was meant for low altitude flight. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. 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). Airplane Plus on SpaceDock Kerbal Space Program - All Easter Eggs Guide 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. How do you get out of a corner when plotting yourself into a corner. If you have an account, sign in now to post with your account. . Clear editor. The most efficient way is, of course, to make a high altitude (or space) plane. AoA and G-force moderation. But you'll need to unlock: Which cost 300 science. This means it is better to have excessive amounts of oxygen than not to. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. As long as the engine gets enough air it will work at proper efficiency. This page was last edited on 22 December 2019, at 20:54. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. Learn more about Stack Overflow the company, and our products. Even up there the plane acts squirrely. Any advices for building a vehicle for this task? Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Fighting oscillations. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. rev2023.3.3.43278. Will post my results. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. TLDR: You need parts you don't have to make a plane that flies that high. Now lets combine these two indicators: The best performance your engine can achieve is when you have an optimal amount of Air Flow (obviously) but also the MAXIMUM amount of Air Intake. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag.

The idea is to slow the plane to a stall above your landing spot the pop the parachute. Long distance airplane flight tips? - Kerbal Space Program Forums 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. Thanks. Let me. This is the first version. Exorcet's Content - Kerbal Space Program Forums You can spin around the whole world on just fumes. Simply changing the intakes made it fly completely out of control and impossible to land. If you have an account, sign in now to post with your account. At altitude the nose goes up and down until it goes out of control. Can't remember where I saw/read about it - Scott Manley maybe? I start with the normal jet engines (which takes almost the complete runway). Display as a link instead, Build a plane or rocket for Kerbal high altitudes - Arqade ksp high altitude plane - digitalidentityorganization.com So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. I'm trying to build a high altitude plane and have found out that the rules are different. ksp high altitude plane. The maximum cruise altitude is just over 40,000 feet. 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. You may be correct and that 3 engine plane is a lemon. Upload or insert images from URL. 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. i dont know what kind of range youre looking for but i would make a significantly smaller plane. You can post now and register later. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? Highest and fastest possible is best. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. 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. The longest flight got them down to a little more than half full. So the faster you go the higher you can fly where there is less drag. 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. This makes jets built using this engine considerably more maneuverable. If it's below the cross-hairs, you need a little more AoA. I did some testing and found that the turbojets get the best Isp around 5.2 km altitude, so I was thinking of flying at that altitude. Yes. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. 2022 Take-Two Interactive Software, Inc. Ok, the panther engine is still not good enough. What am I doing wrong here in the PlotLegends specification. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Powered by Invision Community. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Air Flow: Air Flow represents with how much force air passes the turbine (notice: different amounts of air at the same speed equals in different amounts of force!). The U-2 is probably the highest altitude aircraft still flying. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. 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. FAR is supposed to take aspect into account, but I'm not very experienced with it and cannot advice you as to how it works. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. If it's above the cross-hairs, you need a little less. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space This way control surface max deflection can be programmed by an aircraft designer to make . Kerbal Space Program ( KSP) is a space flight simulation video game developed by Mexican developer Squad for Linux, OS X, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. 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). Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. Don't rely on the efficiency indicator! These are the building blocks of solid spaceplane design!Subscribe! So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less. Press question mark to learn the rest of the keyboard shortcuts. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference.

New comments cannot be posted and votes cannot be cast. 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. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. surface of jool. 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. Thank you, I was able to reach up to 24km altitude with this design. 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. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Plane - Kerbal Space Program Wiki Typically, I watch my Apoapsis as I boost to the high altitude, and there's enough momentum to coast to the peak before completely running out of fuel. J-404 "Panther" Afterburning Turbofan - Kerbal Space Program At about 400-500m/s (~15km), the two engines are even. Been a while since I've flown stock*, but I've heard that, for maximum efficiency, you want one turbojet for every 7.5 tons, and about four ram intakes for each turbojet. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Range with this method is pretty short due to drag. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. a screenshot of kerbal space program 2. by: lord bird. 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). That's because wings need to have some AoA to the airstream in order to generate much lift. I wasn't expecting so many excellent answers! Reddit and its partners use cookies and similar technologies to provide you with a better experience. First off as of .15.1 intakes don't do anything. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. Clear editor. . Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

I also had problems with a high altitude plane until I decided to follow the K.I.S.S. 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. Yes. High altitude planes - Kerbal Space Program Forums Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Content titles and body; Content titles only 2/3 (KSP 1.11.2) - YouTube I break out the Mk2 parts and Panther engines to build a better jet that can go higher and faster. Subscribe -. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. The benefits should be obvious.

Welcome to the forums. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. Since gravity is effectively lower, they don't need as much wing area to maintain altitude-- which, in turn, means less drag, which makes for more efficient flight. 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. Really.

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. (the engines will use very little at high altitude anyway). 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. Cookie Notice CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General 3x06: I design a new, high altitude, jet to collect high atmospheric science. What's the difference between a power rail and a signal line? The second, Wet mode, uses the afterburner to produce thrust almost equal to the J-X4 "Whiplash" Turbo Ramjet Engine, but at a considerably reduced fuel efficiency. Paste as plain text instead, 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. Display as a link instead, So Pvt. You cannot paste images directly. How to tell which packages are held back due to phased updates. Dedicated to the growth and advancement of amateur rocket scientists! 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. [Solved] 30 20 / 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. This thread is quite old. high-2 A Screenshot of Kerbal Space Program A temple in the desert (6 29 47 S 141 40 3 W) known as Tut-Un Jeb-Ahn, although this name can only be seen when a vessel crashes into it. alternatively, combine a liquid fuel rocket into your plane. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. All other versions are slower and lower and unstable in turns. Arqade is a question and answer site for passionate videogamers on all platforms. How do I install mods for Kerbal Space Program 1.1? Watch out for your SAS if you're running batteries without a jet for a long time. 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 my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. 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. Thrust means that slower-is-better no longer applies: now, slower means less drag but more gravity, so there's a tradeoff (which I'm not going to carefully calculate for you, because it's hard). You can do that by right-clicking the engine and clicking "Toggle Mode." 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.

Landing On Laythe Moon Of Jool Kerbal Space Program Youtube This is my current best hi alt plane. It's Kerbal Space Program v.22! 2.) Air temperatures vary with latitude and time of day. Pasted as rich text. I've added more engines, more intakes to no avail. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Personally, I don't enjoy survey contracts on Kerbin. Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. But since when do Kerbals wait for ideal conditions? Clear editor. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Upload or insert images from URL. 1 Pod outside the level 3 VAB. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Using Kolmogorov complexity to measure difficulty of problems? There is a very close tolerance to the two speeds. Here's my example of dealing with the situation. Let me share what I know about jet engines, speed, and efficiency. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. However, it seems as if your delta wing has has more area, might that be it? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. This thread is quite old. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. The returns are diminishing so eventually you will hit a ceiling. I looked into the .cfg files and there are no special properties allocated to them. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes.
