The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. What's the difference between a power rail and a signal line? 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. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. If you want to cover your aircraft with loads of intakes, I'm sure you could easily fly above 35km and reach 2000+ m/s velocity. Don't rely on the efficiency indicator! It only takes a minute to sign up. 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. 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. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. 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. Its an approximation missing someelements. I was hoping that the new intakes would give it the added altitude. The main body is a fuel tank with a Swivel engine at the end. 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. Which lets you go faster, which lets you climb higher. 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. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Plane - Kerbal Space Program Wiki 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. (the engines will use very little at high altitude anyway). 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. The maximum cruise altitude is just over 40,000 feet. Personally, I don't enjoy survey contracts on Kerbin. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. If you have an account, sign in now to post with your account. It is somewhat slow but very steady in flight. As said above, the Wheesley is specifically designed as a low altitude engine. 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. 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. Let me share what I know about jet engines, speed, and efficiency. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. A destructible memorial to the old Mk. (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. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! That's because wings need to have some AoA to the airstream in order to generate much lift. 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. 3x06: I design a new, high altitude, jet to collect high. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). It's Kerbal Space Program v.22! Build a plane or rocket for Kerbal high altitudes, We've added a "Necessary cookies only" option to the cookie consent popup, Screenshot of the Week #85 [Submissions Closed - Vote Now!]. What determines the maximum altitude a plane can reach? 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. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m 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. 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.

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. Airplane Plus on SpaceDock Listen to this guy, don't go much farther above 15000 with high altitude engines. Note: Your post will require moderator approval before it will be visible. Put a couple of radial mount parachutes just above the com and add a reaction wheel. You could try combining the two. Planes and Altitude differences. :: Kerbal Space Program General Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Or try using SRBs instead. I didn't try for 20000m as it probably wouldn't do well. EDIT: Didn't notice you were using FAR. 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. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Remember that you need to have intakes somewhere in line with the engine to function at that altitude. The U-2's published maximum altitude is somewhere above 74,000 feet. 3x06: I design a new, high altitude, jet to collect high atmospheric science. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane Do you know how many intakes/turbojet are needed to run in the regime you described? Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. You can halve the drag by climbing a bit less than 3500m. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. 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. Have you checked out the wiki yet? 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. J-404 "Panther" Afterburning Turbofan - Kerbal Space Program This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. It was meant for low altitude flight. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. high-2 A Screenshot of Kerbal Space Program ksp high altitude plane. 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. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. 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. Information Changelog Stats Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. 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. 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. This works, but it's not optimal. It flames out at 25,000. But. As long as the engine gets enough air it will work at proper efficiency. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. 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. 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. TLDR: You need parts you don't have to make a plane that flies that high. Your previous content has been restored. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate How do you get out of a corner when plotting yourself into a corner. Jets drop thrust at higher altitude and speed, but also drop . Clear editor. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Kerbal Space Program - All Easter Eggs Guide Are you using Stock or NEAR/FAR? Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. This is the first version. Let me. : : . rev2023.3.3.43278. Sub-orbital spaceflight - Wikipedia 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. General Electric F-404 Afterburning Turbofan, Stratus-V Cylindrified Monopropellant Tank, Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine, LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine, T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine, S1 SRB-KD25k "Kickback" Solid Fuel Booster, IX-6315 "Dawn" Electric Propulsion System, AE-FF1 Airstream Protective Shell (1.25m), AE-FF3 Airstream Protective Shell (3.75m), PB-NUK Radioisotope Thermoelectric Generator, https://wiki.kerbalspaceprogram.com/index.php?title=J-404_%22Panther%22_Afterburning_Turbofan&oldid=95515. 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. even stranger is that the surface is textured. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ The benefits should be obvious. Note: Your post will require moderator approval before it will be visible. Paste as plain text instead, 2022 Take-Two Interactive Software, Inc. Whiplash is the engine you would want to use on a plane meant to go 20km. 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. What are the units of measure used in Kerbal Space Program? Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. Ksp engine altitudes : r/KerbalSpaceProgram - reddit Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Grichmann's answer has been the most reliable way I've found to complete these missions. - Spamming airintakes didn't help. Please consider starting a new thread rather than reviving this one. That annoys me but I can't seem to get a design to make it work. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Delta-V is the velocity change necessary to perform orbital maneuvers. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Hello there. 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). 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." You are just about at maximum speed and at the same time very close to stall speed. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. 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. 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 . You can go above 20km with the J-404 Panther. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Learn more about Stack Overflow the company, and our products. Double your speed, you need twice as much fuel. This thread is quite old. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. 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. It will be expensive and time consuming. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Your link has been automatically embedded. What am I doing wrong here in the PlotLegends specification. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. 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). Originally posted by lord bird: yep thats right jool has a surface. air) that high up. Is it even possible? AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. 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!). Aircraft can be very temperamental to fly, especially on the keyboard. 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. You can do that by right-clicking the engine and clicking "Toggle Mode." Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. FBW uses three controllers - pitch, roll and yaw. Your decreased flight time means you probably won't make it to your location. No, I think it's correct, unless I've got a brain fart going, here. 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. So the faster you go the higher you can fly where there is less drag. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. All other versions are slower and lower and unstable in turns. Yes, although they have only been flown with nearly full tanks. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit Long distance airplane flight tips? - Kerbal Space Program Forums Either of the two speeds are to be avoided. 1.) From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Isn't that backwards snark? Early career high altitude observations question : r/KerbalAcademy lost birth certificate near berlin; ksp high altitude plane. Sideslip handling. Please consider starting a new thread rather than reviving this one. You can post now and register later. surface of jool. - Insane lift to weight didn't help. I looked into the .cfg files and there are no special properties allocated to them. Your link has been automatically embedded. 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).

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. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 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. Or about the same speed but 1000 m higher. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! alternatively, combine a liquid fuel rocket into your plane. Steam Workshop::damn wow Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Connect and share knowledge within a single location that is structured and easy to search. 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. Create an account to follow your favorite communities and start taking part in conversations. At altitude the nose goes up and down until it goes out of control. If you have an account, sign in now to post with your account. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Really. Note that you need to activate the afterburner ("Wet Mode") manually. Ep. 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. jet engine efficiency in this game is based on built in thrust curves. Your link has been automatically embedded. What plane in existence can fly at the highest altitude, and - Quora The SR-71 could probably fly higher, but it isn't flying any more. 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. 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. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". 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. Trying to do something without the right part is long and difficult path. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. How do I align things in the following tabular environment? Exorcet's Content - Kerbal Space Program Forums Tutorial: Making the AI fly | BDArmory Wikia | Fandom Arqade is a question and answer site for passionate videogamers on all platforms. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube First is thrust; the higher you get, the lower the thrust your engines deliver. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. You arent doing anything wrong. As has been said, ISP is nothing to worry about. However, I've failed to build a vehicle to achieve this (without a hundred retries). It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Any advices for building a vehicle for this task? As you found out, it basically konks out at 15km. 2022 Take-Two Interactive Software, Inc.
