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 -. 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!). I didn't try for 20000m as it probably wouldn't do well. What are the altitudes for the various altitude record contracts? Double your speed, you need twice as much fuel. 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. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. Ep. How can this new ban on drag possibly be considered constitutional? 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 have an account, sign in now to post with your account. Note: Your post will require moderator approval before it will be visible. Hello there. . Put a couple of radial mount parachutes just above the com and add a reaction wheel. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. AoA and G-force moderation. For more information, please see our Slap that behind a plane you'll be able to go beyond 20km without any trouble. Jet engine - Kerbal Space Program Wiki No, I think it's correct, unless I've got a brain fart going, here. 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. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space This thread is quite old. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. high-2 A Screenshot of Kerbal Space Program Whiplash is the engine you would want to use on a plane meant to go 20km. 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. Kerbal Space Program Jool Landing Youtube. Something that I think has become less clear since someone updated the wiki. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. *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. 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 Let me. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. 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. At altitude the nose goes up and down until it goes out of control. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little 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. Your previous content has been restored. Even up there the plane acts squirrely. How to tell which packages are held back due to phased updates. Tutorial: Making the AI fly | BDArmory Wikia | Fandom 2022 Take-Two Interactive Software, Inc. Have you checked out the wiki yet? Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. You'll notice that usually your prograde marker is slightly below your pitch. Listen to this guy, don't go much farther above 15000 with high altitude engines. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Your link has been automatically embedded. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. 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. But a rockets can do it. Kerbal Space Program - Wikipedia It flames out at 25,000. 2022 Take-Two Interactive Software, Inc. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. Your previous content has been restored. Pasted as rich text. Evidence. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Plane - Kerbal Space Program Wiki In addition to the traditional giant tube of explosions that flings things up high approach, Kerbal Space Program includes a very useful piece of equipment that became quite popular in the 20th century: wings.. As has been said, ISP is nothing to worry about. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit Upload or insert images from URL. For all your gaming related, space exploration needs. Paste as plain text instead, Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) All rights reserved. My question is really about controllability. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. I looked into the .cfg files and there are no special properties allocated to them. 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. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. 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. Imagine that first plane but with the bubble cockpit and the old style round intakes. FBW uses three controllers - pitch, roll and yaw. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. A destructible memorial to the old Mk. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. Delta-v budget - Wikipedia This tutorial will cover designing and flying a plane that can soar at high altitudes! - "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. 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. J-404 "Panther" Afterburning Turbofan - Kerbal Space Program Here's my example of dealing with the situation. That will unlock: I don't have that other stuff yet. Reddit and its partners use cookies and similar technologies to provide you with a better experience. [Solved] 30 20 / 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. Basically I can hit a target altitude of 20,000m but can not maintain it. Only the fuel tanks attached to rockets have any oxidiser in them. Is it even possible? 3x06: I design a new, high altitude, jet to collect high atmospheric science. Press J to jump to the feed. Personally, I don't enjoy survey contracts on Kerbin. If it's below the cross-hairs, you need a little more AoA. Clear editor. 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. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. What plane in existence can fly at the highest altitude, and - Quora KSP - High Altitude Aircraft - YouTube The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. The high performance engine for me performs pretty good till about 15000 meter.

Landing On Laythe Moon Of Jool Kerbal Space Program Youtube 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. Rockets aren t the only way to get to space. 20 votes, 21 comments. @SaintWacko's advice is probably the most practical. Paste as plain text instead, I have enough patience to do the slow flying, but is it horribly inefficient? Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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. 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!]. 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. Watch out for your SAS if you're running batteries without a jet for a long time. Basically you just need to fiddle with it and try some test flights. Or is it the same for all celestial bodies? Using Kolmogorov complexity to measure difficulty of problems? Don't rely on the efficiency indicator! The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. Does a plane consume more fuel if it flies at higher altitudes? Will post my results. 3x06: I design a new, high altitude, jet to collect high. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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. 2.) Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. 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. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. 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. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Laythe - Kerbal Space Program Wiki 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. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 By climbing, you reduce drag, exponentially with altitude. 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 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. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. As you found out, it basically konks out at 15km. They will someday, but they don't now. Spaceplane - Wikipedia Why that? 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. Powered by Invision Community. Hopefully this will be helpful to you. The other one I stay around 6000 meters. Long distance airplane flight tips? - Kerbal Space Program Forums I followed a similar strategy. 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. Most SSTO space planes would be able to accomplish this easily. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. As long as the engine gets enough air it will work at proper efficiency. Sub-orbital spaceflight - Wikipedia To get higher with the low tech jet engines, you need rocket assist. 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. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki 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 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. 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. The U-2's published maximum altitude is somewhere above 74,000 feet. However, it seems as if your delta wing has has more area, might that be it? Ok, the panther engine is still not good enough. Kerbal Space Program - All Easter Eggs Guide 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. 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. At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing.

I'd almost expect it to work better in stock since infini-gliders can be done. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. 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. Are you using Stock or NEAR/FAR? Delta-V is the velocity change necessary to perform orbital maneuvers. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. 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. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! 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. That's because wings need to have some AoA to the airstream in order to generate much lift. Though I'm still working on learning to be better at space planes. 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. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. ksp high altitude plane - digitalidentityorganization.com Trying to do something without the right part is long and difficult path. Display as a link instead, You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. You can go above 20km with the J-404 Panther. Should i add a larger wing area for higher lift? Why not keep the engine for multi-stage rockets? - Space Exploration 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. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. You can do that by right-clicking the engine and clicking "Toggle Mode." What am I doing wrong here in the PlotLegends specification. So the faster you go the higher you can fly where there is less drag. - Insane lift to weight didn't help. Either of the two speeds are to be avoided. Create an account to follow your favorite communities and start taking part in conversations. Of course, this thing has very limited range, speed and acceleration because of the extra weight. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. even stranger is that the surface is textured. High altitude (~20km) possible with normal plane engines? lost birth certificate near berlin; ksp high altitude plane. If you have an account, sign in now to post with your account. It only takes a minute to sign up. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. How can I make money in the new career mode? You are just about at maximum speed and at the same time very close to stall speed. 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)? This works, but it's not optimal. The thrust of jets (turbo or otherwise) depends on airspeed: basics deliver more thrust at low speeds, while turbojets only really come into their own when you fly very fast (which also means flying very high, 20km and over). Don't be too surprised if KSP's aero model breaks down in edge cases. You are simply running out of atmosphere (i.e. When I say ", You know you've nailed it correctly if, when you're in level flight, your. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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. 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). 2022 Take-Two Interactive Software, Inc. I'm trying to build a high altitude plane and have found out that the rules are different. But since when do Kerbals wait for ideal conditions? Cookie Notice There are two factors to that: how thick the air is, how fast the ship is going. The Panther engine can hold 19,000 steady and oscillates around 20,000. You can post now and register later. But you'll need to unlock: Which cost 300 science. Your decreased flight time means you probably won't make it to your location. 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. As said above, the Wheesley is specifically designed as a low altitude engine. 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. 2022 Take-Two Interactive Software, Inc. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. What are the minimum altitudes for each warp level? Then it is "In Space Low over Mun.". This makes jets built using this engine considerably more maneuverable. This is the first version. Press question mark to learn the rest of the keyboard shortcuts. Display as a link instead, In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. It was meant for low altitude flight. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. All the information you could want to know about science, including the altitudes for each celestial body, and what altitudes a given experiment works on are available at: http://wiki.kerbalspaceprogram.com/wiki/Science. Thanks for asking this, I've been struggling with the same problem in career mode. Thanks. Create an account to follow your favorite communities and start taking part in conversations. Is anywhere a list of the altitude levels (I don't know a better term) available? 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. Upload or insert images from URL. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. 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. Is it correct to use "the" before "materials used in making buildings are"?
