If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). When I say ", You know you've nailed it correctly if, when you're in level flight, your. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. 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. Most SSTO space planes would be able to accomplish this easily. 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." Powered by Invision Community. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . I don't have the numbers handy, but you can expect something like 400m/s at 15km. I should perhaps start trying out NEAR to get ready of 0.90, though. 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. 2022 Take-Two Interactive Software, Inc. 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. And it's stock, unfortunately. Air temperatures vary with latitude and time of day. This means it is better to have excessive amounts of oxygen than not to. 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. Hopefully this will be helpful to you. Turbojets are so ridiculously efficient that it doesn't really matter. Clear editor. I've since shaved that down more but that was by going even higher and even faster). In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. 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. 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. Rockets aren t the only way to get to space. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. its rather flat but its a solid surface. This page was last edited on 22 December 2019, at 20:54. The easiest "default" way to build a plane in KSP-- i.e. Don't be too surprised if KSP's aero model breaks down in edge cases. Create an account to follow your favorite communities and start taking part in conversations. Why that? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Proceed with caution. (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. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. As you found out, it basically konks out at 15km. Kerbal Space Program Jool Landing Youtube. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Upload or insert images from URL. It was meant for low altitude flight. - "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. 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. 3x06: I design a new, high altitude, jet to collect high. The U-2 is probably the highest altitude aircraft still flying. This thread is quite old. I don't recall if they model aspect ratio, but either way, the struts are murder and the delta wing has so much more wing that it'll still have more lift. This works, but it's not optimal. 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. Build a plane or rocket for Kerbal high altitudes - Arqade It flames out at 25,000. Welcome to the forums. They will someday, but they don't now. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. TLDR: You need parts you don't have to make a plane that flies that high. Thank you, I was able to reach up to 24km altitude with this design. 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. Ksp engine altitudes : r/KerbalSpaceProgram - reddit The most efficient way is, of course, to make a high altitude (or space) plane. High altitude (~20km) possible with normal plane engines? Kerbal Space Program 2 . You cannot paste images directly. 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. Delta-V is the velocity change necessary to perform orbital maneuvers. With only panthers unlocked I might add. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. This causes the body of your plane to generate additional drag. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Even up there the plane acts squirrely. 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. 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. 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. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. First is thrust; the higher you get, the lower the thrust your engines deliver. What's the difference between a power rail and a signal line? "Whiplash" Turbojet. 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. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Display as a link instead, http://kerbalspaceprogram.com, Press J to jump to the feed. Early career high altitude observations question : r/KerbalAcademy 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. Why do small African island nations perform better than African continental nations, considering democracy and human development? Your previous content has been restored. 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 . Slap that behind a plane you'll be able to go beyond 20km without any trouble. 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). Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V I would like to know which altitude I have to maintain for my experiments. 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. Its an approximation missing someelements. My question is really about controllability. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Upload or insert images from URL. Orbiting is the most fun one: the higher the orbit, the less speed you need to maintain to stay in orbit, *and* the less air there is, so that's a double-whammy in terms of reducing fuel consumption. *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. Planes and Altitude differences. :: Kerbal Space Program General Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. Basically I can hit a target altitude of 20,000m but can not maintain it. You can go above 20km with the J-404 Panther. Don't rely on the efficiency indicator! Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Make sure you have lots of control surfaces because at very high in the atmosphere, there's not much air for the wings to control the craft with. Your link has been automatically embedded. Your answer got me in the right direction, though I ended up with a different design (see my own answer). [Solved] 30 20 / The main body is a fuel tank with a Swivel engine at the end. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Your decreased flight time means you probably won't make it to your location. Something that I think has become less clear since someone updated the wiki. I looked into the .cfg files and there are no special properties allocated to them. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. However, it seems as if your delta wing has has more area, might that be it? 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. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. It will be expensive and time consuming. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. 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. If not, please explain why, which I know you have no problem doing! Mounting a time-limited rescue mission for kerbal inbound to Kerbin. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. 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. Imagine that first plane but with the bubble cockpit and the old style round intakes. For all your gaming related, space exploration needs. Spaceplane - Wikipedia Jets drop thrust at higher altitude and speed, but also drop . I was hoping that the new intakes would give it the added altitude. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Satellite Launcher - Kerbal Space Program Wiki Thanks for the help! 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. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. 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. 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. 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. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. 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. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider.

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. Cheers again fellas. The most efficient way is, of course, to make a high altitude (or space) plane. You can do that by right-clicking the engine and clicking "Toggle Mode." Your previous content has been restored. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. : : . 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 possible to get to an altitude of 16-20km with normal plane engines? 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. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. I followed a similar strategy. Grichman's answer got me in the right direction. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. That will unlock: Either of the two speeds are to be avoided. Then it is "In Space Low over Mun.". Let me share what I know about jet engines, speed, and efficiency. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. 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. June 3, 2022 . 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. But since when do Kerbals wait for ideal conditions? a screenshot of kerbal space program 2. by: lord bird.
