ksp high altitude plane

It may take some practice to hit your target area this way, because you'll be picking up additional horizontal speed, and thus it's possible to under or overshoot. How do I install mods for Kerbal Space Program 1.1? Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. EDIT: Didn't notice you were using FAR. It only takes a minute to sign up. principle. I've been finding it difficult to build a jet that can fly over 15km alt. There is a very close tolerance to the two speeds. 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. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. It is stable but can not maintain altitude. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . What are the altitudes for the various altitude record contracts?

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). The Panther engine can hold 19,000 steady and oscillates around 20,000. I started by attaching two LV-909 rocket engines to a regular low-atmosphere plane: In this save, I don't have custom action groups yet, so I'm using the RCS control to toggle between jet and rocket modes. . Why do small African island nations perform better than African continental nations, considering democracy and human development? At about 400-500m/s (~15km), the two engines are even. If you have an account, sign in now to post with your account. How do I align things in the following tabular environment? What are the units of measure used in Kerbal Space Program? Here's my example of dealing with the situation. 1 Pod outside the level 3 VAB. Display as a link instead, If it's above the cross-hairs, you need a little less. If it's above the cross-hairs, you need a little less. 3x06: I design a new, high altitude, jet to collect high. Your link has been automatically embedded. Main goals: Auto-trimming. No, I think it's correct, unless I've got a brain fart going, here. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. The easiest "default" way to build a plane in KSP-- i.e. I have enough patience to do the slow flying, but is it horribly inefficient? I've added more engines, more intakes to no avail. 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. Ok, the panther engine is still not good enough. 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. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. The other one I stay around 6000 meters. The more successful the flights, the more successful the space program is. Now I have a plane that will fly around the world at an altitude of the low-20s. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum 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. As long a you can fly faster, the lower density at altitude can be compensated for. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. and our June 3, 2022 . Now lets combine these two indicators: The best performance your engine can achieve is when you have an optimal amount of Air Flow (obviously) but also the MAXIMUM amount of Air Intake. Can't remember where I saw/read about it - Scott Manley maybe? Thanks. Even up there the plane acts squirrely. I don't have that other stuff yet. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. A destructible memorial to the old Mk. 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. 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. Thanks for asking this, I've been struggling with the same problem in career mode. Information Changelog Stats So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. They will someday, but they don't now. Pasted as rich text. 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. That annoys me but I can't seem to get a design to make it work. What are the minimum altitudes for each warp level? Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Don't rely on the efficiency indicator! Turbojets are so ridiculously efficient that it doesn't really matter. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. What altitude and speed should I go? Kerbal Space Program 2 . FBW uses three controllers - pitch, roll and yaw. 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. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). TLDR: You need parts you don't have to make a plane that flies that high. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Basically I can hit a target altitude of 20,000m but can not maintain it. But maybe your patience? Create an account to follow your favorite communities and start taking part in conversations. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. To get there, you're going to want to climb at the fastest rate you can manage to 18-20 km, at which point you should mostly level off and start accelerating horizontally.

As you found out, it basically konks out at 15km. 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. I am currently designing a mission that will involve several very long distance plane flights. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. And how many km can I expect to get per v (as calculated by Engineer redux Kerbin atmospheric stats, I know this is weird with planes)? Air Flow + max. high-2 A Screenshot of Kerbal Space Program Press question mark to learn the rest of the keyboard shortcuts. The best answers are voted up and rise to the top, Not the answer you're looking for? It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). 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. Is there a single-word adjective for "having exceptionally strong moral principles"? Cookie Notice Kerbal Space Program Jool Landing Youtube. You need to do it with what you've got. 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. 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. Press J to jump to the feed. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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. This thread is quite old. This lowers their effective "weight"-- for example, a craft flying at 1400 m/s on Kerbin is effectively flying as if gravity were only 2/3 of its actual value. You can post now and register later. For more information, please see our How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. Valve Corporation. All rights reserved. To get higher with the low tech jet engines, you need rocket assist. Highest and fastest possible is best. I was hoping that the new intakes would give it the added altitude. Evidence. I'm going to try adding a small solid fuel rocket engine toned down to get the initial height then dump it, as well as check into that high end gear mentioned. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. You cannot paste images directly. Privacy Policy. You are simply running out of atmosphere (i.e. Paste as plain text instead, a screenshot of kerbal space program 2. by: lord bird. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. This way control surface max deflection can be programmed by an aircraft designer to make . Thank you, I was able to reach up to 24km altitude with this design. But a rockets can do it. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Note: Your post will require moderator approval before it will be visible. I recommend using a solid rocket booster (or 2 or 5) to you get you the altitude and then launch a small rocket powered plane. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Upload or insert images from URL. The U-2's published maximum altitude is somewhere above 74,000 feet. For all your gaming related, space exploration needs. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. http://kerbalspaceprogram.com, Press J to jump to the feed. It is somewhat slow but very steady in flight. Welcome to the forums, ZDW. ksp high altitude plane. Aircraft can be very temperamental to fly, especially on the keyboard. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. *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. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. Imagine that first plane but with the bubble cockpit and the old style round intakes. Display as a link instead, Why do many companies reject expired SSL certificates as bugs in bug bounties? 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. I generally don't fuss with AoI unless I'm making a long range cruiser. 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. 600+ m/s) and low altitudes (e.g. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Your link has been automatically embedded. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. its rather flat but its a solid surface. A jet engine from KSP 0.18 A jet engine is an air-breathing engine which uses onboard liquid fuel and combusts it with the oxygen drawn from the atmosphere. 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. 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). Yes. Connect and share knowledge within a single location that is structured and easy to search. One problem is i'm running stock on career mode and only have 30 part to spare, so large planes are out of the question. 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. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Stoober AK 3.32K subscribers Subscribe 21K views 8 years ago This tutorial will cover designing and flying a plane that can soar. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! What's the difference between a power rail and a signal line? Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. However, I've failed to build a vehicle to achieve this (without a hundred retries). Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. 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. Because when your engine has to take in air forcefully it automatically means there isn't enough surrounding your engine and that again means that air density and therefor air resistance must be pretty low too. Will post my results. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. The most efficient way is, of course, to make a high altitude (or space) plane. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Your previous content has been restored. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. Note: Your post will require moderator approval before it will be visible. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 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. 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. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. 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. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Note: Your post will require moderator approval before it will be visible. 3x06: I design a new, high altitude, jet to collect high atmospheric science. 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. As long as the engine gets enough air it will work at proper efficiency. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. 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. Or is it the same for all celestial bodies? Air temperatures vary with latitude and time of day. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. I would like to know which altitude I have to maintain for my experiments. By climbing, you reduce drag, exponentially with altitude. Have you checked out the wiki yet? This means it is better to have excessive amounts of oxygen than not to. 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. Paste as plain text instead, The main body is a fuel tank with a Swivel engine at the end. 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. Using Kolmogorov complexity to measure difficulty of problems? Your answer got me in the right direction, though I ended up with a different design (see my own answer). But you'll need to unlock: Which cost 300 science. The maximum cruise altitude is just over 40,000 feet. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it.

Fighting oscillations. 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). Put a couple of radial mount parachutes just above the com and add a reaction wheel. You could try combining the two. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. . You'll notice that usually your prograde marker is slightly below your pitch. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. 2022 Take-Two Interactive Software, Inc. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". rev2023.3.3.43278. It flames out at 25,000. These designs are great for getting around Kerbin quickly, but without going orbital. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Most SSTO space planes would be able to accomplish this easily. 2.) Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m 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). In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. You cannot paste images directly. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. How to tell which packages are held back due to phased updates. The Kerbal Space Program subreddit. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it.
