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. The returns are diminishing so eventually you will hit a ceiling. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. 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. Grichman's answer got me in the right direction. 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. But. Now I have a plane that will fly around the world at an altitude of the low-20s. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. 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. Your answer got me in the right direction, though I ended up with a different design (see my own answer). - "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. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. You can spin around the whole world on just fumes. Don't be too surprised if KSP's aero model breaks down in edge cases. Air Flow + max. Thanks. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider.

Ep. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. But since when do Kerbals wait for ideal conditions? What altitude and speed should I go? Slap that behind a plane you'll be able to go beyond 20km without any trouble. Ok, the panther engine is still not good enough. 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. If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Its an approximation missing someelements. 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. I have enough patience to do the slow flying, but is it horribly inefficient? Thanks for the help! It is somewhat slow but very steady in flight. A little while back I spent a long time trying to circumnavigate Kerbin on the least liquid fuel possible (i posted the record to the sub: 254 units of fuel. 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). First is thrust; the higher you get, the lower the thrust your engines deliver. 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. 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. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. This thread is quite old. Really. Have you checked out the wiki yet? Your previous content has been restored. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. I didn't try for 20000m as it probably wouldn't do well. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Paste as plain text instead, It only takes a minute to sign up. alternatively, combine a liquid fuel rocket into your plane. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. The other one I stay around 6000 meters. 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.

Subscribe -. Building a High Altitude Jet | Stream pt. 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. 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 Which lets you go faster, which lets you climb higher. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. 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. With only panthers unlocked I might add. 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). Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Powered by Invision Community. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. The U-2 is probably the highest altitude aircraft still flying. 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 no such thing as "so high radar can not detect it", since radar can detect things in outer space. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! The more successful the flights, the more successful the space program is. Are you using Stock or NEAR/FAR? 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. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). But you'll need to unlock: High Altitude Flight Which cost 300 science. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Then it is "In Space Low over Mun.". If not, please explain why, which I know you have no problem doing! http://kerbalspaceprogram.com, Press J to jump to the feed. Do plugins for Kerbal Space Program work on unix? 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. 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. Hopefully this will be helpful to you. Clear editor. 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. lost birth certificate near berlin; ksp high altitude plane. I've added more engines, more intakes to no avail. "Whiplash" Turbojet. Connect and share knowledge within a single location that is structured and easy to search. a screenshot of kerbal space program 2. by: lord bird. 600+ m/s) and low altitudes (e.g. Welcome to the forums, ZDW. I generally don't fuss with AoI unless I'm making a long range cruiser. This makes jets built using this engine considerably more maneuverable. KSP Career: Episode 13 - High Altitude Surveys Mike Aben 28.5K subscribers Subscribe 7.7K views 7 years ago Day 114: A busy day at the KSC with three missions, the highlights being the launch. However, I've failed to build a vehicle to achieve this (without a hundred retries). The best answers are voted up and rise to the top, Not the answer you're looking for? - "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. Cookie Notice high-2 A Screenshot of Kerbal Space Program Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Only the fuel tanks attached to rockets have any oxidiser in them. FBW uses three controllers - pitch, roll and yaw. Your decreased flight time means you probably won't make it to your location. Pasted as rich text. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). 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. Why is there a voltage on my HDMI and coaxial cables? Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ 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. Challenges At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. You can go above 20km with the J-404 Panther. That will unlock: 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. Don't rely on the efficiency indicator! It flames out at 25,000. 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. Hello there. Information Changelog Stats How do I install mods for Kerbal Space Program 1.1? No, I think it's correct, unless I've got a brain fart going, here. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Planes in Space. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. Yes, although they have only been flown with nearly full tanks. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Range with this method is pretty short due to drag. But you'll need to unlock: Which cost 300 science. Your previous content has been restored. Basically I can hit a target altitude of 20,000m but can not maintain it. 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!). Imagine that first plane but with the bubble cockpit and the old style round intakes. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. Your link has been automatically embedded. I looked into the .cfg files and there are no special properties allocated to them. 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. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Simply changing the intakes made it fly completely out of control and impossible to land. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). 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. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. 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. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. You are just about at maximum speed and at the same time very close to stall speed. For example, the RAPIER engine doesn't seem as the first choice as the "best" high altitude air-breathing engine but in long-distance and high-altitude challenges it is. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Should i add a larger wing area for higher lift? The longest flight got them down to a little more than half full. Press J to jump to the feed. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. 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 Either of the two speeds are to be avoided. However, it seems as if your delta wing has has more area, might that be it? In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. I've been finding it difficult to build a jet that can fly over 15km alt. The high performance engine for me performs pretty good till about 15000 meter. - Insane TWR didn't help. even stranger is that the surface is textured. The U-2's published maximum altitude is somewhere above 74,000 feet. A full suite of flaps on the trailing edges of the main wings give it exceptional low-speed lift, and small hydroplane steps mounted on each side of the fuselage bottom help lift it out of the water (lowering water drag) during takeoff runs. At about 400-500m/s (~15km), the two engines are even. 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. 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. 2022 Take-Two Interactive Software, Inc. Is anywhere a list of the altitude levels (I don't know a better term) available? Can't remember where I saw/read about it - Scott Manley maybe? Arqade is a question and answer site for passionate videogamers on all platforms. I wasn't expecting so many excellent answers! Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). 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. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Even up there the plane acts squirrely. Press question mark to learn the rest of the keyboard shortcuts. This page was last edited on 22 December 2019, at 20:54. 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. Aircraft can be very temperamental to fly, especially on the keyboard. 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. You cannot paste images directly. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Valve Corporation. its rather flat but its a solid surface. It is stable but can not maintain altitude. This means it is better to have excessive amounts of oxygen than not to. All other versions are slower and lower and unstable in turns. You can halve the drag by climbing a bit less than 3500m. Upload or insert images from URL. Put a couple of radial mount parachutes just above the com and add a reaction wheel. Is it correct to use "the" before "materials used in making buildings are"?
