ksp high altitude plane

Long distance airplane flight tips? - Kerbal Space Program Forums Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. The returns are diminishing so eventually you will hit a ceiling. http://www.youtube.com/user/Cruzanak?sub_confirmation=1Quicklinks to topics in this videoJet Engine Concepts: 0:30Air Intakes: 1:13Flameouts: 2:22Control Surfaces: 5:08Flying Tips: 5:57This video will go over everything that you need to know about to design a capable plane that can fly in the thinnest of atmospheres. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. surface of jool. Imagine that first plane but with the bubble cockpit and the old style round intakes. Kerbal Space Program - Wikipedia Remember that you need to have intakes somewhere in line with the engine to function at that altitude. 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 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. What am I doing wrong here in the PlotLegends specification. This thread is quite old. All trademarks are property of their respective owners in the US and other countries. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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. 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. 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. Note that KSP planes get one substantial speed benefit that's much more pronounced than IRL aircraft, due to the freakishly small planet sizes: they're actually flying at a large fraction of orbital velocity. 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. Press question mark to learn the rest of the keyboard shortcuts. Which is capable of high altitude, high speed flight. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. 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. 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. 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. high-2 A Screenshot of Kerbal Space Program Designing a High Altitude Jet | KSP: Making Space Home Mike Aben 24.8K subscribers Join Subscribe 85 Share 3.4K views 1 year ago Ep. The most efficient way is, of course, to make a high altitude (or space) plane. Paste as plain text instead, Note: Your post will require moderator approval before it will be visible. - Spamming airintakes didn't help. I've been finding it difficult to build a jet that can fly over 15km alt. You also need to be going very fast to generate adequate lift at high altitudes and unlike the real U-2, you don't need to fear about overspeeding and destroying the plane. You need to do it with what you've got. For more information, please see our Trying to do something without the right part is long and difficult path. Press question mark to learn the rest of the keyboard shortcuts. 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. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). Laythe - Kerbal Space Program Wiki and our 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. You can halve the drag by climbing a bit less than 3500m. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. 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). Why do many companies reject expired SSL certificates as bugs in bug bounties? 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. Note: Your post will require moderator approval before it will be visible. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram Yes, although they have only been flown with nearly full tanks. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. It may work with stock too, I just don't know. But. i dont know what kind of range youre looking for but i would make a significantly smaller plane. 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. Pasted as rich text. Building a High Altitude Jet | Stream pt. Please consider starting a new thread rather than reviving this one. The most efficient way is, of course, to make a high altitude (or space) plane. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. How can this new ban on drag possibly be considered constitutional? KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Stoober AK 3.32K subscribers Subscribe 21K views 8 years ago This tutorial will cover designing and flying a plane that can soar. Put a couple of radial mount parachutes just above the com and add a reaction wheel. Please consider starting a new thread rather than reviving this one. Main goals: Auto-trimming. 4. Planes in Space - The Kerbal Player's Guide [Book] I start with the normal jet engines (which takes almost the complete runway). You cannot paste images directly. 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. Your link has been automatically embedded. Here's Mr. Manley using it in his tutorial: @Pvt.Grichmann: I think it's at specific locations on Kerbin, not just anywhere above 18km. As you found out, it basically konks out at 15km.

Chapter 4. Evidence. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. You are simply running out of atmosphere (i.e. The U-2's published maximum altitude is somewhere above 74,000 feet. Pasted as rich text. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. There are two factors to that: how thick the air is, how fast the ship is going. 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. I'd almost expect it to work better in stock since infini-gliders can be done. "Whiplash" Turbojet. Have you checked out the wiki yet? Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Is anywhere a list of the altitude levels (I don't know a better term) available? All other versions are slower and lower and unstable in turns. - Insane TWR didn't help. The benefits should be obvious. Your previous content has been restored. Cheers again fellas. 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. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Yes. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. KSP - High Altitude Aircraft - YouTube Basically you just need to fiddle with it and try some test flights. The more successful the flights, the more successful the space program is. My question is really about controllability. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Also, jets eat fuel at pounds-per-minute -- if you cover twice as much ground in the same time, your plane will be more efficient. 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. principle. 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. 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. These are the building blocks of solid spaceplane design!Subscribe! 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!]. Thats my problem right now. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Why not keep the engine for multi-stage rockets? - Space Exploration For all your gaming related, space exploration needs. 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. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. - "In Space High" means your craft is inside the given Sphere of Influence and above the "Space Border" altitude listed in the Celestial Body Multiplier Matrix. But you'll need to unlock: Which cost 300 science. The high performance engine for me performs pretty good till about 15000 meter. Satellite Launcher - Kerbal Space Program Wiki This works, but it's not optimal. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. High altitude (~20km) possible with normal plane engines? If it's below the cross-hairs, you need a little more AoA. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. High altitude planes - Kerbal Space Program Forums Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. 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. So I've created those two planes, both with weasley turbofan engine: This is your problem-- as folks have pointed out, it's not a high-altitude engine. jet engine efficiency in this game is based on built in thrust curves. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Does a plane consume more fuel if it flies at higher altitudes? In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". As has been said, ISP is nothing to worry about. 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." Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Let me. Or try using SRBs instead. With only panthers unlocked I might add. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . You can post now and register later. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Espaol - Latinoamrica (Spanish - Latin America), https://steamcommunity.com/sharedfiles/filedetails/?id=1933948095, https://steamcommunity.com/sharedfiles/filedetails/?id=1933948668, https://steamcommunity.com/sharedfiles/filedetails/?id=1934517923, https://steamcommunity.com/sharedfiles/filedetails/?id=1335577943, https://steamcommunity.com/sharedfiles/filedetails/?id=1640213502, https://steamcommunity.com/sharedfiles/filedetails/?id=1640214586, https://steamcommunity.com/sharedfiles/filedetails/?id=1937826505, https://steamcommunity.com/sharedfiles/filedetails/?id=1937931692. And it's stock, unfortunately. First is thrust; the higher you get, the lower the thrust your engines deliver. Double your speed, you need twice as much fuel. That will unlock: In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. 600+ m/s) and low altitudes (e.g. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? At 3500m, you have half the drag you'd have at the surface; at 7km, 1/4 the drag, at 10.5km, 1/8 the drag, etc. Clear editor. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. ksp high altitude plane - digitalidentityorganization.com 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. Kerbal Space Program Jool Landing Youtube. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 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. 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. 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!). Kerbal Space Program 2 . So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Create an account to follow your favorite communities and start taking part in conversations. 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. Learn more about Stack Overflow the company, and our products. Thanks for asking this, I've been struggling with the same problem in career mode. Planes in Space. Proceed with caution. FBW uses three controllers - pitch, roll and yaw. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. The Kerbal Space Program subreddit. TLDR: You need parts you don't have to make a plane that flies that high. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Personally, I don't enjoy survey contracts on Kerbin. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Early career high altitude observations question : r/KerbalAcademy Slap that behind a plane you'll be able to go beyond 20km without any trouble. 3x06: I design a new, high altitude, jet to collect high. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Here's my example of dealing with the situation. 1.) *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. Build a plane or rocket for Kerbal high altitudes - Arqade 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. What are the altitudes for the various altitude record contracts? A destructible memorial to the old Mk. But a rockets can do it. As long as the engine gets enough air it will work at proper efficiency. 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. Most SSTO space planes would be able to accomplish this easily. 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). Cookie Notice I wasn't expecting so many excellent answers! 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. Paste as plain text instead, Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. What's the difference between a power rail and a signal line? I generally don't fuss with AoI unless I'm making a long range cruiser. Basically I can hit a target altitude of 20,000m but can not maintain it. No, I think it's correct, unless I've got a brain fart going, here. a screenshot of kerbal space program 2. by: lord bird. 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. One problem is i'm running stock on career mode and only have 30 part to spare, so large planes are out of the question. Please consider starting a new thread rather than reviving this one. Any advices for building a vehicle for this task? with a thrust vectoring range of only 3 degrees. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. 1Altitude requirement 2Orbit 3Speed, range, and altitude 4Flight duration 5Flight profiles 5.1Ballistic missiles 5.2Tourist flights 5.3Scientific experiments 5.4Sub-orbital transportation 6Notable uncrewed sub-orbital spaceflights 7Crewed sub-orbital spaceflights 8Future of crewed sub-orbital spaceflight 9See also 10References 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. What are the units of measure used in Kerbal Space Program? 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. These designs are great for getting around Kerbin quickly, but without going orbital. 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 is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. 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. Paste as plain text instead, 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. This means it is better to have excessive amounts of oxygen than not to. However, it seems as if your delta wing has has more area, might that be it? How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit
