They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Thank you, I was able to reach up to 24km altitude with this design. If it's above the cross-hairs, you need a little less. I have enough patience to do the slow flying, but is it horribly inefficient? 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. even stranger is that the surface is textured.
I was hoping that the new intakes would give it the added altitude. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. That's because wings need to have some AoA to the airstream in order to generate much lift. It only takes a minute to sign up. I start with the normal jet engines (which takes almost the complete runway). Anyway thanks in advance. When I say ", You know you've nailed it correctly if, when you're in level flight, your. 2022 Take-Two Interactive Software, Inc. (the engines will use very little at high altitude anyway). 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. Or about the same speed but 1000 m higher.
[Solved] 30 20 / What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. : : . Can't remember where I saw/read about it - Scott Manley maybe?
Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Trying to do something without the right part is long and difficult path. The more successful the flights, the more successful the space program is. 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. Jets drop thrust at higher altitude and speed, but also drop .
Designing a High Altitude Jet | KSP: Making Space Home Why not keep the engine for multi-stage rockets? - Space Exploration 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun I'm trying to build a high altitude plane and have found out that the rules are different. You are simply running out of atmosphere (i.e. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. It is stable but can not maintain altitude. 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. This thread is quite old. The idea is to slow the plane to a stall above your landing spot the pop the parachute. http://kerbalspaceprogram.com, Press J to jump to the feed. I followed a similar strategy. If it's above the cross-hairs, you need a little less. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. The benefits should be obvious. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. - Insane lift to weight didn't help. 1 Pod outside the level 3 VAB. Welcome to the forums, ZDW. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. A destructible memorial to the old Mk. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass.
Airplane Plus on SpaceDock high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. The Panther engine can hold 19,000 steady and oscillates around 20,000.
Tutorial: Making the AI fly | BDArmory Wikia | Fandom 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. 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. . Knowing how to design these types of planes make jumping in to SSTO design very easy as there are only a few minor changes that need to be made.Music Credits:1st Song: \"Elephants\" - YouTube Audio Library2nd Song: \"Hot Heat\" - YouTube Audio Library3rd Song: \"Echoes\" - Kasbo - https://soundcloud.com/k-sboWhat game is this? In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . I've added more engines, more intakes to no avail. But. Sideslip handling. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. And it's stock, unfortunately.
J-404 "Panther" Afterburning Turbofan - Kerbal Space Program 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 flight time won't be as long, but you'll be able to fly a "plane" above 18km. The U-2 is probably the highest altitude aircraft still flying. You are just about at maximum speed and at the same time very close to stall speed. Kerbal Space Program 2 . 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. Yes, although they have only been flown with nearly full tanks. 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). 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 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. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 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). So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. KSP also tends to have very harsh induced drag if angle of attack gets too high. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Is it even possible? Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. What altitude and speed should I go? 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 You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. rev2023.3.3.43278. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect.
As long a you can fly faster, the lower density at altitude can be compensated for. 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 . 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. Either of the two speeds are to be avoided. Air Flow + max. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5.
4. Planes in Space - The Kerbal Player's Guide [Book] List of altitude levels? - Forums - Kerbal Space Program Forums There is a very close tolerance to the two speeds. 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. Download (104.45 MiB) License: CC BY-NC-SA 4.0 Game Version: 1.8.1 Downloads: 371,115 Author: blackheart612 Mod Website: Forum Thread Support this mod: Donate Followers: 626 Outdated Mod This mod is not known to work with the latest version of Kerbal Space Program. 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. Main goals: Auto-trimming. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . 1.) Paste as plain text instead, 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. 2022 Take-Two Interactive Software, Inc. If you have an account, sign in now to post with your account. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. The U-2's published maximum altitude is somewhere above 74,000 feet. Really. EDIT: Didn't notice you were using FAR. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). 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.
Ksp engine altitudes : r/KerbalSpaceProgram - reddit If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. I'd almost expect it to work better in stock since infini-gliders can be done. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Cookie Notice Ep. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. Display as a link instead, *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. 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)? You can post now and register later. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. This thread is quite old. Please consider starting a new thread rather than reviving this one. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes.
Long distance airplane flight tips? - Kerbal Space Program Forums The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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..
Delta-v budget - Wikipedia - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. 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. With the tanks disconnected that way, the rockets don't leach from the jets. 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. . with a thrust vectoring range of only 3 degrees. 600+ m/s) and low altitudes (e.g. 3x06: I design a new, high altitude, jet to collect high atmospheric science. How to tell which packages are held back due to phased updates. As said above, the Wheesley is specifically designed as a low altitude engine. By climbing, you reduce drag, exponentially with altitude. Information Changelog Stats 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. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes.
high altitude flight :: Kerbal Space Program General Discussions She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. To get higher with the low tech jet engines, you need rocket assist. air) that high up. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. You can halve the drag by climbing a bit less than 3500m. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it.
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. - "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. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Air temperatures vary with latitude and time of day.
ksp high altitude plane - digitalidentityorganization.com Grichman's answer got me in the right direction. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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. Your link has been automatically embedded. In the stock atmosphere, the benefits of moving faster outweigh almost everything else.
CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General 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. 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. Your previous content has been restored. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. I should perhaps start trying out NEAR to get ready of 0.90, though. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? 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. This works, but it's not optimal. Is anywhere a list of the altitude levels (I don't know a better term) available?
Kerbin | Kerbal Space Program Wiki | Fandom Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. What are the units of measure used in Kerbal Space Program? Or is it the same for all celestial bodies? alternatively, combine a liquid fuel rocket into your plane. 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. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. The easiest "default" way to build a plane in KSP-- i.e. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate.
Does a plane consume more fuel if it flies at higher altitudes? High altitude (~20km) possible with normal plane engines? 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. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt.
- but they were talking about having two intakes/engine. 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. lost birth certificate near berlin; ksp high altitude plane. Don't rely on the efficiency indicator! Whiplash is the engine you would want to use on a plane meant to go 20km. FBW uses three controllers - pitch, roll and yaw. Valve Corporation. Simply changing the intakes made it fly completely out of control and impossible to land. 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. Rockets aren t the only way to get to space. 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. Challenges 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. 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.
KSP - High Altitude Aircraft - YouTube Hopefully this will be helpful to you. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. TLDR: You need parts you don't have to make a plane that flies that high. 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. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey.
