ksp high altitude plane

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. As said above, the Wheesley is specifically designed as a low altitude engine. alternatively, combine a liquid fuel rocket into your plane. 2.) 2022 Take-Two Interactive Software, Inc. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. Note: Your post will require moderator approval before it will be visible. The U-2 is probably the highest altitude aircraft still flying. Create an account to follow your favorite communities and start taking part in conversations. Though I'm still working on learning to be better at space planes. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? This means it is better to have excessive amounts of oxygen than not to. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. 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)? Double your speed, you need twice as much fuel. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? 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." How can I make money in the new career mode? 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). . Your previous content has been restored. 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. surface of jool. Slap that behind a plane you'll be able to go beyond 20km without any trouble. 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. Note: Your post will require moderator approval before it will be visible. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. 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. I've added more engines, more intakes to no avail. You are simply running out of atmosphere (i.e. But you'll need to unlock: High Altitude Flight Which cost 300 science. *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. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. 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. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. That's because wings need to have some AoA to the airstream in order to generate much lift. 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. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 2/3 (KSP 1.11.2) - YouTube I break out the Mk2 parts and Panther engines to build a better jet that can go higher and faster. Subscribe -. You can post now and register later. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. When I say ", You know you've nailed it correctly if, when you're in level flight, your. At about 400-500m/s (~15km), the two engines are even. But since when do Kerbals wait for ideal conditions? Basically you just need to fiddle with it and try some test flights. Powered by Invision Community. Main goals: Auto-trimming. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Building a rocket to fly vertical seems to be nearly impossible, in the atmosphere they tend to become unstable (or maybe I missed a trick?). Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 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. 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 stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. You can halve the drag by climbing a bit less than 3500m. Ksp engine altitudes 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. Paste as plain text instead, 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. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. This causes the body of your plane to generate additional drag. Or try using SRBs instead. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). jet engine efficiency in this game is based on built in thrust curves. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Of course, this thing has very limited range, speed and acceleration because of the extra weight. The benefits should be obvious. Grichmann's answer has been the most reliable way I've found to complete these missions. You may be correct and that 3 engine plane is a lemon. Press J to jump to the feed. 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. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. I don't have that cockpit in my career game yet, but maybe it will work with the other one. You can do that by right-clicking the engine and clicking "Toggle Mode." FBW uses three controllers - pitch, roll and yaw. I wasn't expecting so many excellent answers! I'd almost expect it to work better in stock since infini-gliders can be done. Evidence. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. So the faster you go the higher you can fly where there is less drag. You arent doing anything wrong. It flames out at 25,000. June 3, 2022 . 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. Let me. The most efficient way is, of course, to make a high altitude (or space) plane. What am I doing wrong here in the PlotLegends specification. Contents 1 Usage 2 Construction 3 Categories 3.1 Airplane 3.2 Seaplane 3.3 Spaceplane 3.4 VTOL 3.5 Glider 3.6 Mothership 4 Operation 4.1 Flight records 5 Notes Usage The Kerbal Space Program subreddit. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ This makes jets built using this engine considerably more maneuverable. Is it even possible? Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Please consider starting a new thread rather than reviving this one. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. 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. Don't worry about Isp. 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. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. 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. The idea is to slow the plane to a stall above your landing spot the pop the parachute. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Pasted as rich text. Which lets you go faster, which lets you climb higher. Your link has been automatically embedded. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. 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. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. 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. Originally posted by lord bird: yep thats right jool has a surface. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. It is stable but can not maintain altitude. The U-2's published maximum altitude is somewhere above 74,000 feet. New comments cannot be posted and votes cannot be cast. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Very cool. 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. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Personally, I don't enjoy survey contracts on Kerbin. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Planes in Space. 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. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. Kerbal Space Program 2 . At altitude the nose goes up and down until it goes out of control. 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). Ok, the panther engine is still not good enough. How do I align things in the following tabular environment? 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? I'm trying to build a high altitude plane and have found out that the rules are different. 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. Paste as plain text instead, Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Highest and fastest possible is best. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Range with this method is pretty short due to drag. How do I install mods for Kerbal Space Program 1.1? 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. Proceed with caution. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. "Whiplash" Turbojet. This works, but it's not optimal. If too little air runs into the turbine your combustion chamber will not be able to burn up fuel effectively due to the lack of oxygen. http://kerbalspaceprogram.com, Press J to jump to the feed. 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. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. They will someday, but they don't now. Here's my example of dealing with the situation. It's Kerbal Space Program v.22! : : . These are the building blocks of solid spaceplane design!Subscribe! 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. Rockets aren t the only way to get to space. What are the minimum altitudes for each warp level? with a thrust vectoring range of only 3 degrees. You can post now and register later. 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!). This is my current best hi alt plane. 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. 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. So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. 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. Is there a single-word adjective for "having exceptionally strong moral principles"? 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. 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 start with the normal jet engines (which takes almost the complete runway). All rights reserved. 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. TLDR: You need parts you don't have to make a plane that flies that high. 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. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. I don't have any exact numbers for you, but you can right-click an engine in flight and it will show both current and optimal airflow, which should hopefully let you work out the best altitude. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Upload or insert images from URL. Thank you, I was able to reach up to 24km altitude with this design. Grichman's answer got me in the right direction. Jets drop thrust at higher altitude and speed, but also drop . In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. - Spamming airintakes didn't help. 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 it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Press question mark to learn the rest of the keyboard shortcuts. high-2 A Screenshot of Kerbal Space Program Thrust means that slower-is-better no longer applies: now, slower means less drag but more gravity, so there's a tradeoff (which I'm not going to carefully calculate for you, because it's hard). Simply changing the intakes made it fly completely out of control and impossible to land. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. a screenshot of kerbal space program 2. by: lord bird. To get higher with the low tech jet engines, you need rocket assist. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Hello there. Connect and share knowledge within a single location that is structured and easy to search. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. even stranger is that the surface is textured. But a rockets can do it. 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. Isn't that backwards snark? It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Anyway thanks in advance. 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. More air is better. 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.

It may work with stock too, I just don't know. Press question mark to learn the rest of the keyboard shortcuts. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). Note: Your post will require moderator approval before it will be visible. You cannot paste images directly. Pvt. Basically I can hit a target altitude of 20,000m but can not maintain it. The easiest "default" way to build a plane in KSP-- i.e. There is a very close tolerance to the two speeds. Display as a link instead, Have you checked out the wiki yet? If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Upload or insert images from URL. Cookie Notice 2022 Take-Two Interactive Software, Inc. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Yes. 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. I didn't try for 20000m as it probably wouldn't do well. Is it possible to get to an altitude of 16-20km with normal plane engines? Are you using Stock or NEAR/FAR? Yes, although they have only been flown with nearly full tanks. Cheers again fellas. 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. ksp high altitude plane. 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. That's all true, but just read the OP: hypersonic appears to be completely out of the question. My 'plane science' is more advanced than my 'rocket science' (career mode) because I got tired of seeing all the high-altitude missions I had on the books and wanted to finish them. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. I don't have that other stuff yet. 3.) This way control surface max deflection can be programmed by an aircraft designer to make . 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. If drag were the only concern, at any given altitude the slower you go, the less fuel you need: the work done by drag over a distance grows linearly with speed (the force grows quadratically with speed, but the time falls linearly). Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. 3x06: I design a new, high altitude, jet to collect high atmospheric science. KSP also tends to have very harsh induced drag if angle of attack gets too high. Its an approximation missing someelements. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Valve Corporation. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. How do you get out of a corner when plotting yourself into a corner. 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. Trying to do something without the right part is long and difficult path. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. With only panthers unlocked I might add. Either of the two speeds are to be avoided. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. - Insane lift to weight didn't help. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.
