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. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. 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 dont know what kind of range youre looking for but i would make a significantly smaller plane. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. 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 -. 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. Is anywhere a list of the altitude levels (I don't know a better term) available? high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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. Upload or insert images from URL. I'm trying to build a high altitude plane and have found out that the rules are different. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Note: Your post will require moderator approval before it will be visible. You arent doing anything wrong. It was meant for low altitude flight. How can this new ban on drag possibly be considered constitutional? Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. 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. For all your gaming related, space exploration needs. Though I'm still working on learning to be better at space planes. 2022 Take-Two Interactive Software, Inc. Note that you need to activate the afterburner ("Wet Mode") manually. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. What's the difference between a power rail and a signal line? 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? Display as a link instead, For more information, please see our I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. It flames out at 25,000. It's also worth noting that this engine has the widest thrust vectoring range of all of the jet engines, with a full 10-degree range in all directions. Your previous content has been restored. 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 If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Thanks for asking this, I've been struggling with the same problem in career mode. Can't remember where I saw/read about it - Scott Manley maybe? 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. - but they were talking about having two intakes/engine. 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. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Your link has been automatically embedded. Press J to jump to the feed. 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. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Really. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Here's my example of dealing with the situation. 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. This means it is better to have excessive amounts of oxygen than not to. Display as a link instead, 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. Main goals: Auto-trimming. They will someday, but they don't now. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. jet engine efficiency in this game is based on built in thrust curves. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. 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. You can spin around the whole world on just fumes. Yes. Trying to do something without the right part is long and difficult path. 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 . EDIT: Didn't notice you were using FAR. 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. Powered by Invision Community. Why do small African island nations perform better than African continental nations, considering democracy and human development? Your previous content has been restored. Which lets you go faster, which lets you climb higher. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. At about 400-500m/s (~15km), the two engines are even. Most SSTO space planes would be able to accomplish this easily. 3.) Let me share what I know about jet engines, speed, and efficiency. *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. Valve Corporation. I wasn't expecting so many excellent answers! So Pvt. 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? In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". The U-2's published maximum altitude is somewhere above 74,000 feet. Which is capable of high altitude, high speed flight. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. AoA and G-force moderation. I start with the normal jet engines (which takes almost the complete runway). A destructible memorial to the old Mk. I have enough patience to do the slow flying, but is it horribly inefficient? Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. To get higher with the low tech jet engines, you need rocket assist. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Note: Your post will require moderator approval before it will be visible. Pasted as rich text. Slap that behind a plane you'll be able to go beyond 20km without any trouble. 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. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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. : : . A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 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. The other one I stay around 6000 meters. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. The Panther engine can hold 19,000 steady and oscillates around 20,000.

Imagine that first plane but with the bubble cockpit and the old style round intakes. air) that high up. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Cookie Notice Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. high-2 A Screenshot of Kerbal Space Program More air is better. Turbojets are so ridiculously efficient that it doesn't really matter. - "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. 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. Evidence. The returns are diminishing so eventually you will hit a ceiling. 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. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake.

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. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Kerbal Space Program Jool Landing Youtube. 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. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. With only panthers unlocked I might add. 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. 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. Your previous content has been restored. All trademarks are property of their respective owners in the US and other countries. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Thats my problem right now. 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. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4.
