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. This means it is better to have excessive amounts of oxygen than not to. 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. Is there a single-word adjective for "having exceptionally strong moral principles"? 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. Range with this method is pretty short due to drag. Note: Your post will require moderator approval before it will be visible. The Kerbal Space Program subreddit.

EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If it's above the cross-hairs, you need a little less. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 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. 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). But a rockets can do it. TLDR: You need parts you don't have to make a plane that flies that high. Your previous content has been restored. Upload or insert images from URL.

Then it is "In Space Low over Mun.". Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. - Insane TWR didn't help. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. Display as a link instead, From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs.

Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. You need to do it with what you've got.

I would like to know which altitude I have to maintain for my experiments. 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. So Pvt. 600+ m/s) and low altitudes (e.g. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. (the engines will use very little at high altitude anyway). Note: Your post will require moderator approval before it will be visible. I've since shaved that down more but that was by going even higher and even faster). 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. 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. 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?

Welcome to the forums. Upload or insert images from URL. 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. This thread is quite old. You arent doing anything wrong. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. I start with the normal jet engines (which takes almost the complete runway). I don't have the numbers handy, but you can expect something like 400m/s at 15km. It is stable but can not maintain altitude. Basically you just need to fiddle with it and try some test flights. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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. Information Changelog Stats This thread is quite old. What am I doing wrong here in the PlotLegends specification. Thrust means that slower-is-better no longer applies: now, slower means less drag but more gravity, so there's a tradeoff (which I'm not going to carefully calculate for you, because it's hard). What determines the maximum altitude a plane can reach? The returns are diminishing so eventually you will hit a ceiling. 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? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. Either of the two speeds are to be avoided. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). http://www.youtube.com/user/Cruzanak?sub_confirmation=1Quicklinks to topics in this videoJet Engine Concepts: 0:30Air Intakes: 1:13Flameouts: 2:22Control Surfaces: 5:08Flying Tips: 5:57This video will go over everything that you need to know about to design a capable plane that can fly in the thinnest of atmospheres. I generally don't fuss with AoI unless I'm making a long range cruiser. However, it seems as if your delta wing has has more area, might that be it? 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. *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. Something that I think has become less clear since someone updated the wiki. There is a very close tolerance to the two speeds. 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!). Why do many companies reject expired SSL certificates as bugs in bug bounties? To reach the initial low Earth orbit of the International Space Stationof 300 km (now 400 km), the delta-v is over six times higher, about 9.4 km/s. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. Early career high altitude observations question : r/KerbalAcademy Content titles and body; Content titles only Hopefully this will be helpful to you. Should i add a larger wing area for higher lift? 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. KSP also tends to have very harsh induced drag if angle of attack gets too high. 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. Don't worry about Isp. Simply changing the intakes made it fly completely out of control and impossible to land. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. KSP Career: Episode 13 - High Altitude Surveys - YouTube 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.

You cannot paste images directly. The most efficient way is, of course, to make a high altitude (or space) plane.
