ksp high altitude plane

I was hoping that the new intakes would give it the added altitude. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. And how many km can I expect to get per v (as calculated by Engineer redux Kerbin atmospheric stats, I know this is weird with planes)? How to tell which packages are held back due to phased updates. Can't remember where I saw/read about it - Scott Manley maybe? 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. I wasn't expecting so many excellent answers! 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. - Insane TWR didn't help. a screenshot of kerbal space program 2. by: lord bird. Note: Your post will require moderator approval before it will be visible. 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. Note: Your post will require moderator approval before it will be visible. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. 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. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. alternatively, combine a liquid fuel rocket into your plane. Why that? Proceed with caution. Personally, I don't enjoy survey contracts on Kerbin. 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. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. But you'll need to unlock: Which cost 300 science. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. I looked into the .cfg files and there are no special properties allocated to them. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. There is a very close tolerance to the two speeds. with a thrust vectoring range of only 3 degrees. Tutorial: Making the AI fly | BDArmory Wikia | Fandom This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. This thread is quite old. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). You may be correct and that 3 engine plane is a lemon. This way control surface max deflection can be programmed by an aircraft designer to make . I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. The SR-71 could probably fly higher, but it isn't flying any more. 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. @SaintWacko's advice is probably the most practical. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. To get higher with the low tech jet engines, you need rocket assist. Kerbal Space Program Jool Landing Youtube. 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. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. KSP also tends to have very harsh induced drag if angle of attack gets too high. If it's below the cross-hairs, you need a little more AoA. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. 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. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Using Kolmogorov complexity to measure difficulty of problems? Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Hello there. You could try combining the two. I should perhaps start trying out NEAR to get ready of 0.90, though. But you'll need to unlock: High Altitude Flight Which cost 300 science. For all your gaming related, space exploration needs. You can do that by right-clicking the engine and clicking "Toggle Mode." My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Long distance airplane flight tips? - Kerbal Space Program Forums 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). jet engine efficiency in this game is based on built in thrust curves. It only takes a minute to sign up. New comments cannot be posted and votes cannot be cast. 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. Why not keep the engine for multi-stage rockets? - Space Exploration 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. If you have an account, sign in now to post with your account. and our Is it suspicious or odd to stand by the gate of a GA airport watching the planes? This makes jets built using this engine considerably more maneuverable. 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. Powered by Invision Community. [Solved] 30 20 / The flight time won't be as long, but you'll be able to fly a "plane" above 18km. But. 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. 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Upload or insert images from URL. 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. So Pvt. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. The main body is a fuel tank with a Swivel engine at the end. I've added more engines, more intakes to no avail. Content titles and body; Content titles only 600+ m/s) and low altitudes (e.g. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. 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. 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. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. So if you want to make a plane go as fast as possible, you want to minimise both angle of attack and angle of incidence necessary to sustain level flight at your target speed and altitude. 1 Pod outside the level 3 VAB. How do you get out of a corner when plotting yourself into a corner. 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!). How can I make money in the new career mode? 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. Satellite Launcher - Kerbal Space Program Wiki http://kerbalspaceprogram.com, Press J to jump to the feed. More air is better. . I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). This causes the body of your plane to generate additional drag. 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. For more information, please see our (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. Isn't that backwards snark? Anyway thanks in advance. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Here's my example of dealing with the situation. : : . From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Something that I think has become less clear since someone updated the wiki. rev2023.3.3.43278.

Why do many companies reject expired SSL certificates as bugs in bug bounties? With only panthers unlocked I might add. With the tanks disconnected that way, the rockets don't leach from the jets. Paste as plain text instead, It may work with stock too, I just don't know. Kerbal Space Program - Wikipedia The Kerbal Space Program subreddit. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Is there a single-word adjective for "having exceptionally strong moral principles"?

Your previous content has been restored. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. List of altitude levels? - Forums - Kerbal Space Program Forums Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Any of my search term words; All of my search term words; Find results in. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. - but they were talking about having two intakes/engine. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Things that work at low altitude don't work so well up high and the plane ends up going up and down while slowly losing speed until it can't maintain altitude anymore. Delta-v budget - Wikipedia Connect and share knowledge within a single location that is structured and easy to search. What plane in existence can fly at the highest altitude, and - Quora So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. That annoys me but I can't seem to get a design to make it work. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. Arqade is a question and answer site for passionate videogamers on all platforms. 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. 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. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. even stranger is that the surface is textured. 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. Hopefully this will be helpful to you. CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! 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 . Your link has been automatically embedded. What's the difference between a power rail and a signal line? Designing a High Altitude Jet | KSP: Making Space Home Even up there the plane acts squirrely. The best answers are voted up and rise to the top, Not the answer you're looking for? Basically I can hit a target altitude of 20,000m but can not maintain it. That will unlock: Press question mark to learn the rest of the keyboard shortcuts. June 3, 2022 . Your decreased flight time means you probably won't make it to your location. Is it even possible? ksp high altitude plane. Does a plane consume more fuel if it flies at higher altitudes? Trying to do something without the right part is long and difficult path. You need to do it with what you've got. This means it is better to have excessive amounts of oxygen than not to. No, I think it's correct, unless I've got a brain fart going, here. It is somewhat slow but very steady in flight. 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. 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. Yes, although they have only been flown with nearly full tanks. Exorcet's Content - Kerbal Space Program Forums Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Grichman's answer got me in the right direction. Early career high altitude observations question : r/KerbalAcademy 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. Do plugins for Kerbal Space Program work on unix? If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. Your previous content has been restored. The high performance engine for me performs pretty good till about 15000 meter. Planes and Altitude differences. :: Kerbal Space Program General 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.

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!]. At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. If it's above the cross-hairs, you need a little less. The Panther engine can hold 19,000 steady and oscillates around 20,000. If it's below the cross-hairs, you need a little more AoA. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram As long as the engine gets enough air it will work at proper efficiency. 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 cannot paste images directly. Sub-orbital spaceflight - Wikipedia 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. Challenges Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Another approach, which I was managing with some success before I figured out jets, is to build a rocket and catapult yourself towards the measurement point. Is it possible to get to an altitude of 16-20km with normal plane engines? Why do small African island nations perform better than African continental nations, considering democracy and human development? High altitude (~20km) possible with normal plane engines? Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. KSP - High Altitude Aircraft - YouTube 2022 Take-Two Interactive Software, Inc. Ep. They will someday, but they don't now. I started by attaching two LV-909 rocket engines to a regular low-atmosphere plane: In this save, I don't have custom action groups yet, so I'm using the RCS control to toggle between jet and rocket modes. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. 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.

Mounting a time-limited rescue mission for kerbal inbound to Kerbin. It's Kerbal Space Program v.22! high altitude flight :: Kerbal Space Program General Discussions 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. air) that high up. Cheers again fellas. I've been finding it difficult to build a jet that can fly over 15km alt. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Then it is "In Space Low over Mun.". Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. It is stable but can not maintain altitude. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Air temperatures vary with latitude and time of day. 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 would like to know which altitude I have to maintain for my experiments. Most SSTO space planes would be able to accomplish this easily. Basically you just need to fiddle with it and try some test flights. What are the units of measure used in Kerbal Space Program? Reddit and its partners use cookies and similar technologies to provide you with a better experience. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Thank you, I was able to reach up to 24km altitude with this design. 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. You arent doing anything wrong. But maybe your patience? As long a you can fly faster, the lower density at altitude can be compensated for. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. What determines the maximum altitude a plane can reach? Ksp engine altitudes : r/KerbalSpaceProgram - reddit Thanks. First is thrust; the higher you get, the lower the thrust your engines deliver. Put a couple of radial mount parachutes just above the com and add a reaction wheel. Any advices for building a vehicle for this task? I am currently designing a mission that will involve several very long distance plane flights. 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. I checked the wiki before I wrote my question, it seems I overread this paragraph Something that I think has become less clear since someone updated the wiki. It will be expensive and time consuming. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. 2022 Take-Two Interactive Software, Inc. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? 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? As you found out, it basically konks out at 15km. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It was meant for low altitude flight. 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. 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. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 1.) 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. 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. 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." Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Kerbin | Kerbal Space Program Wiki | Fandom 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. These designs are great for getting around Kerbin quickly, but without going orbital. I have enough patience to do the slow flying, but is it horribly inefficient? KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V Welcome to the forums. Display as a link instead, "Whiplash" Turbojet. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) 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.
