Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. 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. That's all true, but just read the OP: hypersonic appears to be completely out of the question. Your previous content has been restored. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Please consider starting a new thread rather than reviving this one. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. They will someday, but they don't now. Kerbin | Kerbal Space Program Wiki | Fandom From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. All rights reserved. Whiplash is the engine you would want to use on a plane meant to go 20km. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. New comments cannot be posted and votes cannot be cast. 600+ m/s) and low altitudes (e.g. Or try using SRBs instead. 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. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. What plane in existence can fly at the highest altitude, and - Quora Put a couple of radial mount parachutes just above the com and add a reaction wheel. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. Thanks for the help! This page was last edited on 22 December 2019, at 20:54. Airplane Plus on SpaceDock This means it is better to have excessive amounts of oxygen than not to. This causes the body of your plane to generate additional drag. A jet engine from KSP 0.18 A jet engine is an air-breathing engine which uses onboard liquid fuel and combusts it with the oxygen drawn from the atmosphere. Display as a link instead, 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. Does a plane consume more fuel if it flies at higher altitudes? high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. For more information, please see our You need to do it with what you've got. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. - Insane TWR didn't help. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. and our 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. I would like to know which altitude I have to maintain for my experiments. It is usually best for initial designs to be based on logic and real-world physics and then be prepared to experiment with non-logical alternatives for optimisation. I don't have that cockpit in my career game yet, but maybe it will work with the other one. How do you get out of a corner when plotting yourself into a corner. I was hoping that the new intakes would give it the added altitude. Kerbal Space Program 2 . Using Kolmogorov complexity to measure difficulty of problems? Don't be too surprised if KSP's aero model breaks down in edge cases. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. Hopefully this will be helpful to you. A destructible memorial to the old Mk. 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. Personally, I don't enjoy survey contracts on Kerbin. It's Kerbal Space Program v.22! jet engine efficiency in this game is based on built in thrust curves. 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. As long a you can fly faster, the lower density at altitude can be compensated for. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. It is somewhat slow but very steady in flight. Pasted as rich text. 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. Or is it the same for all celestial bodies? As has been said, ISP is nothing to worry about. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. [Solved] 30 20 / *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. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. 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. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Why that? How do I install mods for Kerbal Space Program 1.1? If it's above the cross-hairs, you need a little less. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun Watch out for your SAS if you're running batteries without a jet for a long time. How can I make money in the new career mode? Of course, this thing has very limited range, speed and acceleration because of the extra weight. This thread is quite old. First is thrust; the higher you get, the lower the thrust your engines deliver. You can spin around the whole world on just fumes. Your answer got me in the right direction, though I ended up with a different design (see my own answer). 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. 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. 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. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube But maybe your patience? 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? I am currently designing a mission that will involve several very long distance plane flights. Listen to this guy, don't go much farther above 15000 with high altitude engines. What am I doing wrong here in the PlotLegends specification. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. More air is better. ksp high altitude plane - digitalidentityorganization.com They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Spaceplane - Wikipedia - Insane lift to weight didn't help. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Please consider starting a new thread rather than reviving this one. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Evidence. 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. 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. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. principle. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. As said above, the Wheesley is specifically designed as a low altitude engine. 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. Air temperatures vary with latitude and time of day. I've since shaved that down more but that was by going even higher and even faster). Upload or insert images from URL. (the engines will use very little at high altitude anyway). Turbojets are so ridiculously efficient that it doesn't really matter. Create an account to follow your favorite communities and start taking part in conversations. I've added more engines, more intakes to no avail. AoA and G-force moderation. Rockets aren t the only way to get to space. 3x06: I design a new, high altitude, jet to collect high. 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. Trying to do something without the right part is long and difficult path. You are simply running out of atmosphere (i.e. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. That's because wings need to have some AoA to the airstream in order to generate much lift. Pasted as rich text. 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. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? KSP Career: Episode 13 - High Altitude Surveys - YouTube Press question mark to learn the rest of the keyboard shortcuts.

It was meant for low altitude flight. Can't remember where I saw/read about it - Scott Manley maybe? You'll notice that usually your prograde marker is slightly below your pitch. What's the difference between a power rail and a signal line? Or about the same speed but 1000 m higher. Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. Is anywhere a list of the altitude levels (I don't know a better term) available? Designing a High Altitude Jet | KSP: Making Space Home 2022 Take-Two Interactive Software, Inc. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Something that I think has become less clear since someone updated the wiki. It is stable but can not maintain altitude. 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. 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. All other versions are slower and lower and unstable in turns. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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. I looked into the .cfg files and there are no special properties allocated to them. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. List of altitude levels? - Forums - Kerbal Space Program Forums This way control surface max deflection can be programmed by an aircraft designer to make . You may be correct and that 3 engine plane is a lemon. Please consider starting a new thread rather than reviving this one. Why do small African island nations perform better than African continental nations, considering democracy and human development? Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. This is the first version. Should i add a larger wing area for higher lift? Challenges Why not keep the engine for multi-stage rockets? - Space Exploration 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!). You cannot paste images directly. You cannot paste images directly. even stranger is that the surface is textured. That annoys me but I can't seem to get a design to make it work. And it's stock, unfortunately. Pvt. This is my current best hi alt plane.
