ksp high altitude plane

Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. Be sure to have enough intakes (I think maximum efficiency in stock is 1 ramjet intake per ~2 tons of plane, though that is aesthetically ridiculous), and if you're still running short of intake air, you can dip down a bit to speed up and get to denser air. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). These designs are great for getting around Kerbin quickly, but without going orbital. I don't have the numbers handy, but you can expect something like 400m/s at 15km. Grichmann's answer has been the most reliable way I've found to complete these missions. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Let me share what I know about jet engines, speed, and efficiency. You may be correct and that 3 engine plane is a lemon. But you'll need to unlock: Which cost 300 science. I am currently designing a mission that will involve several very long distance plane flights. 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. That will unlock: Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. 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. Of course, this thing has very limited range, speed and acceleration because of the extra weight. 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. I have enough patience to do the slow flying, but is it horribly inefficient? The idea is to slow the plane to a stall above your landing spot the pop the parachute. Also, jets eat fuel at pounds-per-minute -- if you cover twice as much ground in the same time, your plane will be more efficient. Press question mark to learn the rest of the keyboard shortcuts. (the engines will use very little at high altitude anyway). A destructible memorial to the old Mk. How to tell which packages are held back due to phased updates. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. All trademarks are property of their respective owners in the US and other countries. 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. Basically you just need to fiddle with it and try some test flights. Why is there a voltage on my HDMI and coaxial cables? Range with this method is pretty short due to drag. 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. This page was last edited on 22 December 2019, at 20:54. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Can't remember where I saw/read about it - Scott Manley maybe? What are the altitudes for the various altitude record contracts? Turbojets are so ridiculously efficient that it doesn't really matter. 1.) This causes the body of your plane to generate additional drag. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. Thats my problem right now. Things that work at low altitude don't work so well up high and the plane ends up going up and down while slowly losing speed until it can't maintain altitude anymore. This works, but it's not optimal. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) Its an approximation missing someelements. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Kerbal Space Program - Wikipedia The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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. General Electric F-404 Afterburning Turbofan, Stratus-V Cylindrified Monopropellant Tank, Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine, LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine, T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine, S1 SRB-KD25k "Kickback" Solid Fuel Booster, IX-6315 "Dawn" Electric Propulsion System, AE-FF1 Airstream Protective Shell (1.25m), AE-FF3 Airstream Protective Shell (3.75m), PB-NUK Radioisotope Thermoelectric Generator, https://wiki.kerbalspaceprogram.com/index.php?title=J-404_%22Panther%22_Afterburning_Turbofan&oldid=95515. 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. KSP also tends to have very harsh induced drag if angle of attack gets too high. ksp high altitude plane - digitalidentityorganization.com I start with the normal jet engines (which takes almost the complete runway). High altitude planes - Kerbal Space Program Forums With the tanks disconnected that way, the rockets don't leach from the jets. 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. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. No, I think it's correct, unless I've got a brain fart going, here. 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. It is stable but can not maintain altitude. high-2 A Screenshot of Kerbal Space Program Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. 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. 2022 Take-Two Interactive Software, Inc. 1 Pod outside the level 3 VAB. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Create an account to follow your favorite communities and start taking part in conversations. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). 4. Planes in Space - The Kerbal Player's Guide [Book] Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Reddit and its partners use cookies and similar technologies to provide you with a better experience. What determines the maximum altitude a plane can reach? TLDR: You need parts you don't have to make a plane that flies that high. [Solved] 30 20 / Trying to do something without the right part is long and difficult path. It only takes a minute to sign up. With only panthers unlocked I might add. Display as a link instead, - Spamming airintakes didn't help. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Then it is "In Space Low over Mun.". http://kerbalspaceprogram.com, Press J to jump to the feed. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Beginner's Guide: Tips and Basics - Kerbal Space Program 2 Wiki Guide - IGN Isn't that backwards snark? Press J to jump to the feed. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. As has been said, ISP is nothing to worry about. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.. Visit Stack Exchange Thanks. 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 Either of the two speeds are to be avoided. I've since shaved that down more but that was by going even higher and even faster). CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General 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. This is the first version. jet engine efficiency in this game is based on built in thrust curves. FBW uses three controllers - pitch, roll and yaw. 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. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. 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). . lost birth certificate near berlin; ksp high altitude plane. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. 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. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. The U-2's published maximum altitude is somewhere above 74,000 feet. 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. i dont know what kind of range youre looking for but i would make a significantly smaller plane. 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).

How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ If it's below the cross-hairs, you need a little more AoA. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. It may work with stock too, I just don't know. By climbing, you reduce drag, exponentially with altitude. If it's above the cross-hairs, you need a little less. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. Pasted as rich text. Ksp engine altitudes : r/KerbalSpaceProgram - reddit There are two factors to that: how thick the air is, how fast the ship is going. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Designing a High Altitude Jet | KSP: Making Space Home Powered by Invision Community. If it's above the cross-hairs, you need a little less. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun Double your speed, you need twice as much fuel. You'll notice that usually your prograde marker is slightly below your pitch. 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. Will post my results. Originally posted by lord bird: yep thats right jool has a surface. Air temperatures vary with latitude and time of day. You cannot paste images directly. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Slap that behind a plane you'll be able to go beyond 20km without any trouble. The longest flight got them down to a little more than half full. 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. 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 enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. air) that high up. Most SSTO space planes would be able to accomplish this easily.
