I didn't try for 20000m as it probably wouldn't do well. 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. jet engine efficiency in this game is based on built in thrust curves. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. This thread is quite old. 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. Create an account to follow your favorite communities and start taking part in conversations. As long as the engine gets enough air it will work at proper efficiency. To get higher with the low tech jet engines, you need rocket assist. Range with this method is pretty short due to drag. You can post now and register later. - Insane TWR didn't help. Don't rely on the efficiency indicator! By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft).

Aircraft can be very temperamental to fly, especially on the keyboard. 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. 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. Which is capable of high altitude, high speed flight. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. You can go above 20km with the J-404 Panther. TLDR: You need parts you don't have to make a plane that flies that high. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Arqade is a question and answer site for passionate videogamers on all platforms. 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. This is the first version. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. 1.) The U-2 is probably the highest altitude aircraft still flying. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 3x06: I design a new, high altitude, jet to collect high. Your previous content has been restored. These are the building blocks of solid spaceplane design!Subscribe! Dedicated to the growth and advancement of amateur rocket scientists! It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. 1 Pod outside the level 3 VAB. a screenshot of kerbal space program 2. by: lord bird. . If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. The SR-71 could probably fly higher, but it isn't flying any more. 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. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. This causes the body of your plane to generate additional drag. I don't have that other stuff yet. 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. 2022 Take-Two Interactive Software, Inc. 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. Please consider starting a new thread rather than reviving this one. So Pvt. You may be correct and that 3 engine plane is a lemon. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. 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. 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. The high performance engine for me performs pretty good till about 15000 meter. Fighting oscillations. The main body is a fuel tank with a Swivel engine at the end. Your link has been automatically embedded. 3.) If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. There are two factors to that: how thick the air is, how fast the ship is going. If not, please explain why, which I know you have no problem doing! The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Is it even possible? Is it possible to get to an altitude of 16-20km with normal plane engines? Let me share what I know about jet engines, speed, and efficiency. However, it seems as if your delta wing has has more area, might that be it? - "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. 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. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. I've since shaved that down more but that was by going even higher and even faster). Clear editor. The Panther engine can hold 19,000 steady and oscillates around 20,000. Anyway thanks in advance. I wasn't expecting so many excellent answers! What are the units of measure used in Kerbal Space Program? Note: Your post will require moderator approval before it will be visible. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. 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. Basically I can hit a target altitude of 20,000m but can not maintain it. Or try using SRBs instead. 600+ m/s) and low altitudes (e.g. The benefits should be obvious. Why do small African island nations perform better than African continental nations, considering democracy and human development? 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 Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. Press J to jump to the feed. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Welcome to the forums. The most efficient way is, of course, to make a high altitude (or space) plane. By climbing, you reduce drag, exponentially with altitude. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. This thread is quite old. Is it correct to use "the" before "materials used in making buildings are"? Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. 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. 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)? Of course, this thing has very limited range, speed and acceleration because of the extra weight. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Information Changelog Stats AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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." Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. You can post now and register later. You can post now and register later. Paste as plain text instead, I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Most SSTO space planes would be able to accomplish this easily. Powered by Invision Community. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. This means it is better to have excessive amounts of oxygen than not to. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. 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. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Pasted as rich text. Please consider starting a new thread rather than reviving this one. high-2 A Screenshot of Kerbal Space Program - "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. Its an approximation missing someelements. 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 can spin around the whole world on just fumes. Why is there a voltage on my HDMI and coaxial cables? It only takes a minute to sign up. (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. Yes. Privacy Policy. 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. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Using Kolmogorov complexity to measure difficulty of problems? The maximum cruise altitude is just over 40,000 feet. Only the fuel tanks attached to rockets have any oxidiser in them. Any of my search term words; All of my search term words; Find results in. How do I install mods for Kerbal Space Program 1.1? @SaintWacko's advice is probably the most practical. In the main KSP settings menu you should set the default throttle to 1.0 (technically the above mechjeb setting winds up restoring the default throttle, so it needs to be 1.0) In the attitude adjustment menu make sure you are using the "better controller" Whack the 45 degree phase margin button Whack the restore all other defaults button This way control surface max deflection can be programmed by an aircraft designer to make . All other versions are slower and lower and unstable in turns. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. 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. 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. Originally posted by lord bird: yep thats right jool has a surface. This works, but it's not optimal. Yes. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Very cool. I looked into the .cfg files and there are no special properties allocated to them. 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. 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 At about 400-500m/s (~15km), the two engines are even. 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. Can't remember where I saw/read about it - Scott Manley maybe? Which lets you go faster, which lets you climb higher. Is there a single-word adjective for "having exceptionally strong moral principles"? 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. If it's above the cross-hairs, you need a little less. Sideslip handling. That annoys me but I can't seem to get a design to make it work. 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. Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude.
