If it's above the cross-hairs, you need a little less. 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. No, I think it's correct, unless I've got a brain fart going, here. 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. Note that you need to activate the afterburner ("Wet Mode") manually. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. 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. a screenshot of kerbal space program 2. by: lord bird. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. 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). Cheers again fellas. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. Your previous content has been restored. . 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. Kerbal Space Program 2 . Is it correct to use "the" before "materials used in making buildings are"? Rockets aren t the only way to get to space. 3x06: I design a new, high altitude, jet to collect high atmospheric science. 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. For more information, please see our 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. Press question mark to learn the rest of the keyboard shortcuts. How do I install mods for Kerbal Space Program 1.1? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. How do I align things in the following tabular environment? FBW uses three controllers - pitch, roll and yaw. You may be correct and that 3 engine plane is a lemon. You are just about at maximum speed and at the same time very close to stall speed. First is thrust; the higher you get, the lower the thrust your engines deliver. (the engines will use very little at high altitude anyway). Of course, this thing has very limited range, speed and acceleration because of the extra weight. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Thanks for asking this, I've been struggling with the same problem in career mode. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. There is a very close tolerance to the two speeds. Though I'm still working on learning to be better at space planes. Connect and share knowledge within a single location that is structured and easy to search. 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Please consider starting a new thread rather than reviving this one. http://kerbalspaceprogram.com, Press J to jump to the feed. 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. 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!]. I've added more engines, more intakes to no avail. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? But a rockets can do it. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. Now lets combine these two indicators: The best performance your engine can achieve is when you have an optimal amount of Air Flow (obviously) but also the MAXIMUM amount of Air Intake. 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. Watch out for your SAS if you're running batteries without a jet for a long time. Please consider starting a new thread rather than reviving this one. Thanks for the help! Evidence. 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? 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. It may work with stock too, I just don't know. All trademarks are property of their respective owners in the US and other countries. Clear editor. 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. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. So Pvt. I've since shaved that down more but that was by going even higher and even faster). Challenges When you are surrounded by plenty of air there will of course be no need to suck in air artificially but the higher you get the less dense the air around you becomes and in order to make sure that your engines have enough oxygen to burn the fuel it needs to suck air in forcefully. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude. The other one I stay around 6000 meters. 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. Paste as plain text instead, Reddit and its partners use cookies and similar technologies to provide you with a better experience. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. This way control surface max deflection can be programmed by an aircraft designer to make . Arqade is a question and answer site for passionate videogamers on all platforms. The high performance engine for me performs pretty good till about 15000 meter. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Proceed with caution. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. Chapter 4. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Something that I think has become less clear since someone updated the wiki. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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). Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. You arent doing anything wrong. *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. 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. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Turbojets are so ridiculously efficient that it doesn't really matter. 600+ m/s) and low altitudes (e.g. Is it possible to get to an altitude of 16-20km with normal plane engines? The idea is to slow the plane to a stall above your landing spot the pop the parachute. 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. 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'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. 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. Yes, although they have only been flown with nearly full tanks. Only the fuel tanks attached to rockets have any oxidiser in them. EDIT: Didn't notice you were using FAR. Information Changelog Stats 2.) 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. I didn't try for 20000m as it probably wouldn't do well. 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." And it's stock, unfortunately. with a thrust vectoring range of only 3 degrees. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. They will someday, but they don't now. This thread is quite old. surface of jool. With the tanks disconnected that way, the rockets don't leach from the jets. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Air Flow + max. Don't be too surprised if KSP's aero model breaks down in edge cases. The longest flight got them down to a little more than half full. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. What are the altitudes for the various altitude record contracts? Using Kolmogorov complexity to measure difficulty of problems? I did some testing and found that the turbojets get the best Isp around 5.2 km altitude, so I was thinking of flying at that altitude. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. 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. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. 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. What are the units of measure used in Kerbal Space Program? Hello there. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. I've been finding it difficult to build a jet that can fly over 15km alt. If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. 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. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. 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. 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. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path.

One problem is i'm running stock on career mode and only have 30 part to spare, so large planes are out of the question. I was hoping that the new intakes would give it the added altitude. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. But since when do Kerbals wait for ideal conditions? 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. At altitude the nose goes up and down until it goes out of control. Aircraft can be very temperamental to fly, especially on the keyboard. 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 . 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? The returns are diminishing so eventually you will hit a ceiling. You can post now and register later. These designs are great for getting around Kerbin quickly, but without going orbital. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. air) that high up. Please consider starting a new thread rather than reviving this one. June 3, 2022 . If you have an account, sign in now to post with your account. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Sideslip handling. But maybe your patience? This works, but it's not optimal. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. 2022 Take-Two Interactive Software, Inc. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate But you'll need to unlock: High Altitude Flight Which cost 300 science. Learn more about Stack Overflow the company, and our products. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Remember that you need to have intakes somewhere in line with the engine to function at that altitude. Pasted as rich text. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". How can I make money in the new career mode? You can post now and register later. The more successful the flights, the more successful the space program is. Why do small African island nations perform better than African continental nations, considering democracy and human development? high-2 A Screenshot of Kerbal Space Program My question is really about controllability. 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. The easiest "default" way to build a plane in KSP-- i.e. All rights reserved. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. This page was last edited on 22 December 2019, at 20:54. Don't worry about Isp. AoA and G-force moderation. This is my current best hi alt plane. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Really. It's Kerbal Space Program v.22! Contents 1 Usage 2 Construction 3 Categories 3.1 Airplane 3.2 Seaplane 3.3 Spaceplane 3.4 VTOL 3.5 Glider 3.6 Mothership 4 Operation 4.1 Flight records 5 Notes Usage Is it suspicious or odd to stand by the gate of a GA airport watching the planes? 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. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. With only panthers unlocked I might add. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. How to tell which packages are held back due to phased updates. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. But you'll need to unlock: Which cost 300 science. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. The maximum cruise altitude is just over 40,000 feet. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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. What are the minimum altitudes for each warp level? Pasted as rich text. As you found out, it basically konks out at 15km. I am currently designing a mission that will involve several very long distance plane flights. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. @SaintWacko's advice is probably the most practical. principle. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. It flames out at 25,000. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Press J to jump to the feed. You can do that by right-clicking the engine and clicking "Toggle Mode." A full suite of flaps on the trailing edges of the main wings give it exceptional low-speed lift, and small hydroplane steps mounted on each side of the fuselage bottom help lift it out of the water (lowering water drag) during takeoff runs. How do you get out of a corner when plotting yourself into a corner. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. Or about the same speed but 1000 m higher. Your link has been automatically embedded. TLDR: You need parts you don't have to make a plane that flies that high. There are two factors to that: how thick the air is, how fast the ship is going. Paste as plain text instead, Upload or insert images from URL. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Why that? These are the building blocks of solid spaceplane design!Subscribe! 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. Planes in Space. That's all true, but just read the OP: hypersonic appears to be completely out of the question. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Either of the two speeds are to be avoided. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If it's below the cross-hairs, you need a little more AoA. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. Or is it the same for all celestial bodies? It only takes a minute to sign up. As long as the engine gets enough air it will work at proper efficiency. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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. 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. 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!).
