Slap that behind a plane you'll be able to go beyond 20km without any trouble. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Kerbal Space Program ( KSP) is a space flight simulation video game developed by Mexican developer Squad for Linux, OS X, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. 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. Create an account to follow your favorite communities and start taking part in conversations. Is it correct to use "the" before "materials used in making buildings are"? I generally don't fuss with AoI unless I'm making a long range cruiser. 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). Pasted as rich text. 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?). i dont know what kind of range youre looking for but i would make a significantly smaller plane. The SR-71 could probably fly higher, but it isn't flying any more. Something that I think has become less clear since someone updated the wiki. 20 votes, 21 comments. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. 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. 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. 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. Cheers again fellas. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. For more information, please see our If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Stoober AK 3.32K subscribers Subscribe 21K views 8 years ago This tutorial will cover designing and flying a plane that can soar. Most SSTO space planes would be able to accomplish this easily. 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. It flames out at 25,000. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. Grichman's answer got me in the right direction. 3x06: I design a new, high altitude, jet to collect high. All other versions are slower and lower and unstable in turns. Air temperatures vary with latitude and time of day. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. 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. Though I'm still working on learning to be better at space planes. 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. 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. I wasn't expecting so many excellent answers! Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). That's all true, but just read the OP: hypersonic appears to be completely out of the question. 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 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. 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. 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. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. http://kerbalspaceprogram.com, Press J to jump to the feed.

Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). 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. rev2023.3.3.43278. Privacy Policy. The best answers are voted up and rise to the top, Not the answer you're looking for? Your decreased flight time means you probably won't make it to your location. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. Double your speed, you need twice as much fuel. Please consider starting a new thread rather than reviving this one. air) that high up. its rather flat but its a solid surface. 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). More air is better. Yes. How do I install mods for Kerbal Space Program 1.1? 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. . It's Kerbal Space Program v.22! If it's above the cross-hairs, you need a little less. You can go above 20km with the J-404 Panther. Imagine that first plane but with the bubble cockpit and the old style round intakes. 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. At about 400-500m/s (~15km), the two engines are even. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. 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. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Display as a link instead, 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. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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. And it's stock, unfortunately. This way control surface max deflection can be programmed by an aircraft designer to make . Even up there the plane acts squirrely. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Thanks for the help! When I say ", You know you've nailed it correctly if, when you're in level flight, your. It is stable but can not maintain altitude. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). That annoys me but I can't seem to get a design to make it work. Don't worry about Isp. Fighting oscillations. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. June 3, 2022 . The other one I stay around 6000 meters. 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? Personally, I don't enjoy survey contracts on Kerbin. Paste as plain text instead, Upload or insert images from URL. ksp high altitude plane. At that point your engines will be running about .7-.8 efficiency and you will be out of the thicker atmo which will allow you to go faster. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Or is it the same for all celestial bodies? Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Powered by Invision Community. Press J to jump to the feed. 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. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. The Kerbal Space Program subreddit. Jets drop thrust at higher altitude and speed, but also drop . As long a you can fly faster, the lower density at altitude can be compensated for. Don't be too surprised if KSP's aero model breaks down in edge cases. You can do that by right-clicking the engine and clicking "Toggle Mode." - "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. Yes. Learn more about Stack Overflow the company, and our products. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. 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. 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. 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. Cookie Notice and our 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. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. 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. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 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. It has two modes: The first, Dry mode, is similar to that of the J-33 "Wheesley" Basic Jet Engine, with a bit more thrust. At sea level, it produces 120 kn thrust, but at 15 km altitude, it only produces 13.7 kn of thrust, barely enough to provide any thrust to climb higher, Long and narrow wing has less surface area to provide lift, and at higher altitude, the atmospher is so thin that the lift generated by long and narrow wings is insufficient for sustainable flight. Grichmann's answer has been the most reliable way I've found to complete these missions. Thanks for asking this, I've been struggling with the same problem in career mode. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. That's because wings need to have some AoA to the airstream in order to generate much lift. Press question mark to learn the rest of the keyboard shortcuts. - but they were talking about having two intakes/engine. TLDR: You need parts you don't have to make a plane that flies that high. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. First is thrust; the higher you get, the lower the thrust your engines deliver. What are the units of measure used in Kerbal Space Program? Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. - Insane lift to weight didn't help. So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less. Let me. But maybe your patience? I'm in career mode and got all groups of the 45-science-cost level, except Flight Control, and additionally have Electrics, Heavy Rocketry and Fuel Systems. I'd almost expect it to work better in stock since infini-gliders can be done. 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 This page was last edited on 22 December 2019, at 20:54. 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. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Please consider starting a new thread rather than reviving this one. 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. What are the minimum altitudes for each warp level? There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Your link has been automatically embedded. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Now I have a plane that will fly around the world at an altitude of the low-20s. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Using Kolmogorov complexity to measure difficulty of problems? 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. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. What are the altitudes for the various altitude record contracts? The maximum cruise altitude is just over 40,000 feet. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Ep. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. 2022 Take-Two Interactive Software, Inc. If it's below the cross-hairs, you need a little more AoA. 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). Building a High Altitude Jet | Stream pt. I looked into the .cfg files and there are no special properties allocated to them. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. I should perhaps start trying out NEAR to get ready of 0.90, though. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. I don't have that other stuff yet. 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. 1 Pod outside the level 3 VAB. You arent doing anything wrong. You are simply running out of atmosphere (i.e. You may be correct and that 3 engine plane is a lemon. I was hoping that the new intakes would give it the added altitude. 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? Let me share what I know about jet engines, speed, and efficiency. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. Main goals: Auto-trimming. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Is it even possible? 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. You could try combining the two. 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 Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. 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 -. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. 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. 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. 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. This causes the body of your plane to generate additional drag. edited 6 yr. ago. 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. 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. Pasted as rich text. The most efficient way is, of course, to make a high altitude (or space) plane. If not, please explain why, which I know you have no problem doing! Welcome to the forums. Listen to this guy, don't go much farther above 15000 with high altitude engines. As has been said, ISP is nothing to worry about. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. EDIT: Didn't notice you were using FAR. Or about the same speed but 1000 m higher. 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. Range with this method is pretty short due to drag. 2.) probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. The returns are diminishing so eventually you will hit a ceiling. Clear editor. 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. The main body is a fuel tank with a Swivel engine at the end. A destructible memorial to the old Mk. Trying to do something without the right part is long and difficult path. What's the difference between a power rail and a signal line? I have enough patience to do the slow flying, but is it horribly inefficient? You cannot paste images directly. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. 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. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Is there a single-word adjective for "having exceptionally strong moral principles"? - "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. For all your gaming related, space exploration needs. With the tanks disconnected that way, the rockets don't leach from the jets. 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. Watch out for your SAS if you're running batteries without a jet for a long time. How to tell which packages are held back due to phased updates. even stranger is that the surface is textured. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Display as a link instead, I didn't try for 20000m as it probably wouldn't do well. Are you using Stock or NEAR/FAR? No, I think it's correct, unless I've got a brain fart going, here. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. If you have an account, sign in now to post with your account. Originally posted by lord bird: yep thats right jool has a surface. Your answer got me in the right direction, though I ended up with a different design (see my own answer).
