I should perhaps start trying out NEAR to get ready of 0.90, though. For all your gaming related, space exploration needs. But. Turbojets are so ridiculously efficient that it doesn't really matter. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Welcome to the forums, ZDW. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. It may work with stock too, I just don't know. Ok, the panther engine is still not good enough. I looked into the .cfg files and there are no special properties allocated to them. Air Flow + max. As said above, the Wheesley is specifically designed as a low altitude engine. You can post now and register later. Even up there the plane acts squirrely. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. Hopefully this will be helpful to you. (Actually, four ways: but balloons aren't in the stock game) Lifting surfaces are great but they lose effectiveness just as fast with altitude as drag falls. You cannot paste images directly. You can spin around the whole world on just fumes. 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 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 . Don't worry about Isp. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Connect and share knowledge within a single location that is structured and easy to search. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. I don't have that other stuff yet. Now I have a plane that will fly around the world at an altitude of the low-20s. 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. This tutorial will cover designing and flying a plane that can soar at high altitudes! Dedicated to the growth and advancement of amateur rocket scientists! 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. Please consider starting a new thread rather than reviving this one. . Don't be too surprised if KSP's aero model breaks down in edge cases. As long as the engine gets enough air it will work at proper efficiency. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. These designs are great for getting around Kerbin quickly, but without going orbital. I don't have any exact numbers for you, but you can right-click an engine in flight and it will show both current and optimal airflow, which should hopefully let you work out the best altitude. Cheers again fellas. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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. 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). jet engine efficiency in this game is based on built in thrust curves. Clear editor. 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). In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Slap that behind a plane you'll be able to go beyond 20km without any trouble. I'm trying to build a high altitude plane and have found out that the rules are different. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Put a couple of radial mount parachutes just above the com and add a reaction wheel. The most efficient way is, of course, to make a high altitude (or space) plane. 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?). The main body is a fuel tank with a Swivel engine at the end. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. That will unlock: This means it is better to have excessive amounts of oxygen than not to. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! This thread is quite old. Its an approximation missing someelements. 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. Trying to do something without the right part is long and difficult path. - "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. So the faster you go the higher you can fly where there is less drag. Isn't that backwards snark? All other versions are slower and lower and unstable in turns. Air temperatures vary with latitude and time of day. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. 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 wasn't expecting so many excellent answers! If drag were the only concern, at any given altitude the slower you go, the less fuel you need: the work done by drag over a distance grows linearly with speed (the force grows quadratically with speed, but the time falls linearly). The Kerbal Space Program subreddit. 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. 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. The most efficient way is, of course, to make a high altitude (or space) plane. 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. So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. The benefits should be obvious. - Insane TWR didn't help. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. 2022 Take-Two Interactive Software, Inc. If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. I was hoping that the new intakes would give it the added altitude. Pasted as rich text. and our Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! If you have an account, sign in now to post with your account. - "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. 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 -. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Don't rely on the efficiency indicator! high-2 A Screenshot of Kerbal Space Program Main goals: Auto-trimming. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? - Spamming airintakes didn't help. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. You need to do it with what you've got. Basically you just need to fiddle with it and try some test flights. Using Kolmogorov complexity to measure difficulty of problems? 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. If it's below the cross-hairs, you need a little more AoA. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

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. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Is it even possible? If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Though I'm still working on learning to be better at space planes. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Paste as plain text instead, Sideslip handling. It is somewhat slow but very steady in flight. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Yes, although they have only been flown with nearly full tanks. The U-2 is probably the highest altitude aircraft still flying. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. This thread is quite old. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Highest and fastest possible is best. Thanks. 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. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Press question mark to learn the rest of the keyboard shortcuts. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Your link has been automatically embedded. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. It was meant for low altitude flight. You cannot paste images directly. But you'll need to unlock: Which cost 300 science. 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. However, it seems as if your delta wing has has more area, might that be it? Very cool. Upload or insert images from URL. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft.
