Pvt. 2022 Take-Two Interactive Software, Inc. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. Why do many companies reject expired SSL certificates as bugs in bug bounties? How do I install mods for Kerbal Space Program 1.1? Upload or insert images from URL. Is it suspicious or odd to stand by the gate of a GA airport watching the planes?

Kerbal Space Program 2 . The main body is a fuel tank with a Swivel engine at the end. First is thrust; the higher you get, the lower the thrust your engines deliver. 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? How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. . And it's stock, unfortunately. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. 20 votes, 21 comments. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. That will unlock: Is it correct to use "the" before "materials used in making buildings are"? It may work with stock too, I just don't know. 3x06: I design a new, high altitude, jet to collect high atmospheric science. Your previous content has been restored. i dont know what kind of range youre looking for but i would make a significantly smaller plane. KSP also tends to have very harsh induced drag if angle of attack gets too high. 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. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. This thread is quite old. 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. Are you using Stock or NEAR/FAR? As has been said, ISP is nothing to worry about. This way control surface max deflection can be programmed by an aircraft designer to make . ksp high altitude plane. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Simply changing the intakes made it fly completely out of control and impossible to land. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. *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. 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 . 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. a screenshot of kerbal space program 2. by: lord bird. 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. Is there a single-word adjective for "having exceptionally strong moral principles"? Thanks. 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. No, I think it's correct, unless I've got a brain fart going, here. So the faster you go the higher you can fly where there is less drag. 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. The U-2's published maximum altitude is somewhere above 74,000 feet. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. You are simply running out of atmosphere (i.e. The easiest "default" way to build a plane in KSP-- i.e. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Welcome to the forums. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. It only takes a minute to sign up. Or is it the same for all celestial bodies? As long as the engine gets enough air it will work at proper efficiency. 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. For all your gaming related, space exploration needs. Building a High Altitude Jet | Stream pt. If it's below the cross-hairs, you need a little more AoA. surface of jool. Powered by Invision Community. 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. 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. Clear editor. 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. Basically I can hit a target altitude of 20,000m but can not maintain it. Basically you just need to fiddle with it and try some test flights. Rockets aren t the only way to get to space. 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? Either of the two speeds are to be avoided. I start with the normal jet engines (which takes almost the complete runway). If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Create an account to follow your favorite communities and start taking part in conversations. 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). @SaintWacko's advice is probably the most practical. Something that I think has become less clear since someone updated the wiki. Learn more about Stack Overflow the company, and our products. 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. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. You are just about at maximum speed and at the same time very close to stall speed. However, I've failed to build a vehicle to achieve this (without a hundred retries). Yes, although they have only been flown with nearly full tanks. The Kerbal Space Program subreddit. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). 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. 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.. - "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. 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. What's the difference between a power rail and a signal line? Listen to this guy, don't go much farther above 15000 with high altitude engines. What are the altitudes for the various altitude record contracts? Pasted as rich text. Why do small African island nations perform better than African continental nations, considering democracy and human development? edited 6 yr. ago. If it's below the cross-hairs, you need a little more AoA. Isn't that backwards snark? Ep. - Insane lift to weight didn't help. Reddit and its partners use cookies and similar technologies to provide you with a better experience. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. 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. Fighting oscillations. Note that you need to activate the afterburner ("Wet Mode") manually. 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 Which is capable of high altitude, high speed flight. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. You need to do it with what you've got. Will post my results. But a rockets can do it. I am currently designing a mission that will involve several very long distance plane flights. It is somewhat slow but very steady in flight. Grichman's answer got me in the right direction. 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. That's all true, but just read the OP: hypersonic appears to be completely out of the question. All rights reserved. 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. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies.

Please consider starting a new thread rather than reviving this one. There are two factors to that: how thick the air is, how fast the ship is going. If you have an account, sign in now to post with your account. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. I decided to look into that two intakes thing, and it turns out to make 11-12 m/s difference at 19,000m with my plane. Highest and fastest possible is best. 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. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. 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. 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. 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 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. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. So long as there's only one high-altitude measurement to take, you should be able to complete a whole set of 3-4 in one flight. It flames out at 25,000. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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.
