Your previous content has been restored. Or about the same speed but 1000 m higher. EDIT: Didn't notice you were using FAR. Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. KSP Career: Episode 13 - High Altitude Surveys - YouTube 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 -. Early career high altitude observations question : r/KerbalAcademy The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. This thread is quite old. The more successful the flights, the more successful the space program is. It's Kerbal Space Program v.22! rev2023.3.3.43278. Are you using Stock or NEAR/FAR? Something that I think has become less clear since someone updated the wiki. 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). A destructible memorial to the old Mk. "Whiplash" Turbojet. Proceed with caution. Sideslip handling. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. ksp high altitude plane. Learn more about Stack Overflow the company, and our products. 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. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Press J to jump to the feed. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Designing a High Altitude Jet | KSP: Making Space Home Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Air temperatures vary with latitude and time of day. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. 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. High altitude planes - Kerbal Space Program Forums AoA and G-force moderation. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Does a plane consume more fuel if it flies at higher altitudes? It will be expensive and time consuming. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. 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. This thread is quite old. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. Originally posted by lord bird: yep thats right jool has a surface. 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?). Note that keeping the plane weight low is critical, only carry a very small amount of fuel. So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. Slap that behind a plane you'll be able to go beyond 20km without any trouble. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. One of my planes is small and agile, and can easily enough glide to a safe landing even if the rockets consume all the fuel. 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. Planes in Space. 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. (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. The Panther engine can hold 19,000 steady and oscillates around 20,000. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. How do you get out of a corner when plotting yourself into a corner. 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.. Visit Stack Exchange Don't be too surprised if KSP's aero model breaks down in edge cases. Content titles and body; Content titles only 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. Your previous content has been restored. Which is capable of high altitude, high speed flight. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. Spaceplane - Wikipedia Why do many companies reject expired SSL certificates as bugs in bug bounties? 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. As you found out, it basically konks out at 15km. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Sub-orbital spaceflight - Wikipedia And it's stock, unfortunately. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Personally, I don't enjoy survey contracts on Kerbin. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. It was meant for low altitude flight. Cheers again fellas. Yes. You cannot paste images directly. You can do that by right-clicking the engine and clicking "Toggle Mode." Of course, this thing has very limited range, speed and acceleration because of the extra weight. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) You cannot paste images directly. Long distance airplane flight tips? - Kerbal Space Program Forums TLDR: You need parts you don't have to make a plane that flies that high. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Planes and Altitude differences. :: Kerbal Space Program General How can I make money in the new career mode? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. I don't have any exact numbers for you, but you can right-click an engine in flight and it will show both current and optimal airflow, which should hopefully let you work out the best altitude. These designs are great for getting around Kerbin quickly, but without going orbital. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. 3x06: I design a new, high altitude, jet to collect high. To avoid running out of fuel altogether, I have a second plane with small tanks (no oxidizer) attached directly to the jet engines, and the rockets attached behind the fuselage, which is entirely oxidized tanks. The Kerbal Space Program subreddit. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. What are the altitudes for the various altitude record contracts? What are the units of measure used in Kerbal Space Program? Tutorial: Making the AI fly | BDArmory Wikia | Fandom 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. with a thrust vectoring range of only 3 degrees. Powered by Invision Community. 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). How do I install mods for Kerbal Space Program 1.1? 1 1: The basics 2 2: Setting it up 3 3: First flight 4 4: Finishing touches 1: The basics First of all, you're going to need an airplane. The most efficient way is, of course, to make a high altitude (or space) plane. What's the difference between a power rail and a signal line? Thats my problem right now. Powered by Invision Community, Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane, I was generally under the impression that basic jets were mostly deadweight on high-performance aircraft: [] at hypersonic velocities. Fighting oscillations.

Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. You can post now and register later. 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. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. 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. You can spin around the whole world on just fumes. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. 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. You'll notice that usually your prograde marker is slightly below your pitch. Your link has been automatically embedded. Can't remember where I saw/read about it - Scott Manley maybe? At altitude the nose goes up and down until it goes out of control. 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. 3x06: I design a new, high altitude, jet to collect high atmospheric science. Upload or insert images from URL. Why do small African island nations perform better than African continental nations, considering democracy and human development? Kerbal Space Program - All Easter Eggs Guide The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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. Press question mark to learn the rest of the keyboard shortcuts. Hello there. I didn't try for 20000m as it probably wouldn't do well. 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). In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". I have enough patience to do the slow flying, but is it horribly inefficient? Kerbal Space Program 2 . Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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. ksp high altitude plane - digitalidentityorganization.com It only takes a minute to sign up. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. I'm trying to build a high altitude plane and have found out that the rules are different. You could try combining the two. High altitude (~20km) possible with normal plane engines? Thank you, I was able to reach up to 24km altitude with this design. Main goals: Auto-trimming. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. 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. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube That annoys me but I can't seem to get a design to make it work. 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. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . 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. Watch out for your SAS if you're running batteries without a jet for a long time. 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. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. Dedicated to the growth and advancement of amateur rocket scientists! - but they were talking about having two intakes/engine. You cannot paste images directly. 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. That's all true, but just read the OP: hypersonic appears to be completely out of the question. 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. Laythe - Kerbal Space Program Wiki Cookie Notice It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The U-2 is probably the highest altitude aircraft still flying. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Your decreased flight time means you probably won't make it to your location. KSP - High Altitude Aircraft - YouTube Pasted as rich text. My question is really about controllability. Jet engine - Kerbal Space Program Wiki How to tell which packages are held back due to phased updates. 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. [Solved] 30 20 / Please consider starting a new thread rather than reviving this one. This is my current best hi alt plane. Thanks for asking this, I've been struggling with the same problem in career mode. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space.

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. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. This way control surface max deflection can be programmed by an aircraft designer to make . Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. I'm going to try adding a small solid fuel rocket engine toned down to get the initial height then dump it, as well as check into that high end gear mentioned. The high performance engine for me performs pretty good till about 15000 meter. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. Your answer got me in the right direction, though I ended up with a different design (see my own answer). The ideal case for optimally efficient flight (which is what you want if you're trying to maximize cruise altitude) is when your wings are mounted to the body, pitched up just enough that when cruising in level flight, the body of the aircraft is pointing perfectly . Display as a link instead, 20 votes, 21 comments. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Clear editor. 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. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. So Pvt. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. 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. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). 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. 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. As has been said, ISP is nothing to worry about. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Why not keep the engine for multi-stage rockets? - Space Exploration a screenshot of kerbal space program 2. by: lord bird. As long as the engine gets enough air it will work at proper efficiency. Don't worry about Isp. 4. Planes in Space - The Kerbal Player's Guide [Book] Incidentally, for these speeds and altitudes, ordinary jets are the better choice. This causes the body of your plane to generate additional drag. *I use FAR these days, which basically means completely replacing every spaceplane and rocket you ever designed to account for its much more realistic aerodynamics. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space I would like to know which altitude I have to maintain for my experiments. 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. : : . If you have an account, sign in now to post with your account. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. New comments cannot be posted and votes cannot be cast. Is anywhere a list of the altitude levels (I don't know a better term) available? 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. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. You need to do it with what you've got. KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V Simply changing the intakes made it fly completely out of control and impossible to land. As long a you can fly faster, the lower density at altitude can be compensated for. 600+ m/s) and low altitudes (e.g. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. With the tanks disconnected that way, the rockets don't leach from the jets. Press question mark to learn the rest of the keyboard shortcuts. I start with the normal jet engines (which takes almost the complete runway). The drag differential is because your long-wing layout is using a bunch of struts, and the reason your delta-wing has a higher ceiling is because it has more wing area to provide lift. FBW uses three controllers - pitch, roll and yaw. air) that high up. KSP also tends to have very harsh induced drag if angle of attack gets too high. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. Not only does it conk out at high altitudes, but also it conks out at high speeds, and you need to be able to go fast to fly up high. 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. I've since shaved that down more but that was by going even higher and even faster). What altitude and speed should I go? Control Sensativty for Planes - KSP2 Suggestions and Development
