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. Don't rely on the efficiency indicator! That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. If it's above the cross-hairs, you need a little less. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. There are two factors to that: how thick the air is, how fast the ship is going. It flames out at 25,000. 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. You are simply running out of atmosphere (i.e. jet engine efficiency in this game is based on built in thrust curves. Your answer got me in the right direction, though I ended up with a different design (see my own answer). As long as the engine gets enough air it will work at proper efficiency. Grichman's answer got me in the right direction. It is somewhat slow but very steady in flight. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. When I say ", You know you've nailed it correctly if, when you're in level flight, your. Hopefully this will be helpful to you. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Arqade is a question and answer site for passionate videogamers on all platforms. You cannot paste images directly. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. http://kerbalspaceprogram.com, Press J to jump to the feed. Main goals: Auto-trimming. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Why that? If it's below the cross-hairs, you need a little more AoA. 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. - "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. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). Paste as plain text instead, Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. What are the minimum altitudes for each warp level? with a thrust vectoring range of only 3 degrees.

How do I install mods for Kerbal Space Program 1.1? 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? 1Altitude requirement 2Orbit 3Speed, range, and altitude 4Flight duration 5Flight profiles 5.1Ballistic missiles 5.2Tourist flights 5.3Scientific experiments 5.4Sub-orbital transportation 6Notable uncrewed sub-orbital spaceflights 7Crewed sub-orbital spaceflights 8Future of crewed sub-orbital spaceflight 9See also 10References Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. All trademarks are property of their respective owners in the US and other countries. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. However, I've failed to build a vehicle to achieve this (without a hundred retries). Basically I can hit a target altitude of 20,000m but can not maintain it. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. What am I doing wrong here in the PlotLegends specification. 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. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Challenges 2022 Take-Two Interactive Software, Inc. 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. Or try using SRBs instead. 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). I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. Your previous content has been restored. There is a very close tolerance to the two speeds. 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. 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. You cannot paste images directly. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Isn't that backwards snark? I'd almost expect it to work better in stock since infini-gliders can be done. If not, please explain why, which I know you have no problem doing! 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!]. 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. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. I should perhaps start trying out NEAR to get ready of 0.90, though. 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. Building a High Altitude Jet | Stream pt. 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. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. Your previous content has been restored. This page was last edited on 22 December 2019, at 20:54. 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. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Basically you just need to fiddle with it and try some test flights. The main body is a fuel tank with a Swivel engine at the end. I would like to know which altitude I have to maintain for my experiments. Highest and fastest possible is best. its rather flat but its a solid surface. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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!). Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. Is it possible to get to an altitude of 16-20km with normal plane engines? Do plugins for Kerbal Space Program work on unix? 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. Thanks for the help! For more information, please see our I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. "Whiplash" Turbojet. This makes jets built using this engine considerably more maneuverable. By climbing, you reduce drag, exponentially with altitude. Clear editor. Is there a single-word adjective for "having exceptionally strong moral principles"? I was hoping that the new intakes would give it the added altitude. How can this new ban on drag possibly be considered constitutional? 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. Can't remember where I saw/read about it - Scott Manley maybe? Your link has been automatically embedded. Clear editor. - "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. 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. That will unlock: 3x06: I design a new, high altitude, jet to collect high atmospheric science. This works, but it's not optimal. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. 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. I have enough patience to do the slow flying, but is it horribly inefficient? Kerbal Space Program Jool Landing Youtube. 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 To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. 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. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. 1.) Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. Chapter 4. 2022 Take-Two Interactive Software, Inc. high-2 A Screenshot of Kerbal Space Program Upload or insert images from URL. As you found out, it basically konks out at 15km. Originally posted by lord bird: yep thats right jool has a surface. Display as a link instead, Which is capable of high altitude, high speed flight. Dedicated to the growth and advancement of amateur rocket scientists! Then it is "In Space Low over Mun.". I've since shaved that down more but that was by going even higher and even faster). 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. Range with this method is pretty short due to drag. I looked into the .cfg files and there are no special properties allocated to them. That's because wings need to have some AoA to the airstream in order to generate much lift. But a rockets can do it. But since when do Kerbals wait for ideal conditions? I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). You may be correct and that 3 engine plane is a lemon. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. To avoid running out of fuel altogether, I have a second plane with small tanks (no oxidizer) attached directly to the jet engines, and the rockets attached behind the fuselage, which is entirely oxidized tanks. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. Is it even possible? Thanks. 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. Trying to do something without the right part is long and difficult path. How do you get out of a corner when plotting yourself into a corner. 3.)

It only takes a minute to sign up. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ You could try combining the two. To get higher with the low tech jet engines, you need rocket assist. principle. 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. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. But maybe your patience? Of course, this thing has very limited range, speed and acceleration because of the extra weight. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Building a rocket to fly vertical seems to be nearly impossible, in the atmosphere they tend to become unstable (or maybe I missed a trick?). What's the difference between a power rail and a signal line? There's basically three ways to do that: lifting surfaces, thrust, and orbiting. What altitude and speed should I go? This thread is quite old. I start with the normal jet engines (which takes almost the complete runway). 2.) The longest flight got them down to a little more than half full. 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 -. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. lost birth certificate near berlin; ksp high altitude plane. 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. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! 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). 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. Let me. Press J to jump to the feed. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? Incidentally, for these speeds and altitudes, ordinary jets are the better choice. The easiest "default" way to build a plane in KSP-- i.e. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. Why do small African island nations perform better than African continental nations, considering democracy and human development? I didn't try for 20000m as it probably wouldn't do well. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Note: Your post will require moderator approval before it will be visible. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Watch out for your SAS if you're running batteries without a jet for a long time. You are just about at maximum speed and at the same time very close to stall speed. Display as a link instead, So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less.
