a screenshot of kerbal space program 2. by: lord bird. Really. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Sideslip handling. Don't be too surprised if KSP's aero model breaks down in edge cases. If you have an account, sign in now to post with your account. It may work with stock too, I just don't know. 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. 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. I wasn't expecting so many excellent answers! Simply changing the intakes made it fly completely out of control and impossible to land. Display as a link instead, EDIT: Didn't notice you were using FAR. If it's above the cross-hairs, you need a little less. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. 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. How to tell which packages are held back due to phased updates. It's Kerbal Space Program v.22! 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. No, I think it's correct, unless I've got a brain fart going, here. 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). From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Kerbal Space Program - Wikipedia Any advices for building a vehicle for this task? I should perhaps start trying out NEAR to get ready of 0.90, though. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Ideally, you'll want to avoid these contracts until you get the High-Altitude Flight tech node and the improved jet engine that comes with it. Information Changelog Stats Pasted as rich text. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Isn't that backwards snark? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. All trademarks are property of their respective owners in the US and other countries. Airplane Plus on SpaceDock Remember that you need to have intakes somewhere in line with the engine to function at that altitude. These are the building blocks of solid spaceplane design!Subscribe! Hopefully this will be helpful to you. . 2.) Does a plane consume more fuel if it flies at higher altitudes? Arqade is a question and answer site for passionate videogamers on all platforms. FBW uses three controllers - pitch, roll and yaw. Valve Corporation. Have you checked out the wiki yet? Which is capable of high altitude, high speed flight. Thanks. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. 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. They will someday, but they don't now. I was hoping that the new intakes would give it the added altitude. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". The Kerbal Space Program subreddit. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Delta-V is the velocity change necessary to perform orbital maneuvers. GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space Let me. Thats my problem right now. 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. How can I make money in the new career mode? Ksp engine altitudes 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. Kerbin | Kerbal Space Program Wiki | Fandom At sea level, it produces 120 kn thrust, but at 15 km altitude, it only produces 13.7 kn of thrust, barely enough to provide any thrust to climb higher, Long and narrow wing has less surface area to provide lift, and at higher altitude, the atmospher is so thin that the lift generated by long and narrow wings is insufficient for sustainable flight. Ep. The best answers are voted up and rise to the top, Not the answer you're looking for? If you have an account, sign in now to post with your account. Note that you need to activate the afterburner ("Wet Mode") manually. This makes jets built using this engine considerably more maneuverable. The benefits should be obvious. For more information, please see our If not, please explain why, which I know you have no problem doing! Upload or insert images from URL. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. 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. - Insane TWR didn't help. high altitude flight :: Kerbal Space Program General Discussions - Insane lift to weight didn't help. There are two factors to that: how thick the air is, how fast the ship is going. Upload or insert images from URL. 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. air) that high up. Or try using SRBs instead. 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. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. Range with this method is pretty short due to drag. Grichman's answer got me in the right direction. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Highest and fastest possible is best. 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. Cheers again fellas. Another approach, which I was managing with some success before I figured out jets, is to build a rocket and catapult yourself towards the measurement point. Don't worry about Isp. But. The thrust of jets (turbo or otherwise) depends on airspeed: basics deliver more thrust at low speeds, while turbojets only really come into their own when you fly very fast (which also means flying very high, 20km and over). 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. Paste as plain text instead, How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit Privacy Policy. Then it is "In Space Low over Mun.". Kerbal Space Program - All Easter Eggs Guide alternatively, combine a liquid fuel rocket into your plane. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 4. Planes in Space - The Kerbal Player's Guide [Book] I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. By climbing, you reduce drag, exponentially with altitude. This thread is quite old. 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. @SaintWacko's advice is probably the most practical. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Kerbal Space Program Jool Landing Youtube. What altitude and speed should I go? Spaceplane - Wikipedia That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). If too little air runs into the turbine your combustion chamber will not be able to burn up fuel effectively due to the lack of oxygen. 3x06: I design a new, high altitude, jet to collect high atmospheric science. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Listen to this guy, don't go much farther above 15000 with high altitude engines. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Or about the same speed but 1000 m higher. Chapter 4. Kerbal Space Program 2 . This tutorial will cover designing and flying a plane that can soar at high altitudes! EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Satellite Launcher - Kerbal Space Program Wiki It was meant for low altitude flight. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Pvt. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. Learn more about Stack Overflow the company, and our products. Plane - Kerbal Space Program Wiki high-2 A Screenshot of Kerbal Space Program Is it suspicious or odd to stand by the gate of a GA airport watching the planes? If it's below the cross-hairs, you need a little more AoA. It is somewhat slow but very steady in flight. You could try combining the two. 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). Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Paste as plain text instead, 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). The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Please consider starting a new thread rather than reviving this one. 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. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram Of course, this thing has very limited range, speed and acceleration because of the extra weight. The easiest "default" way to build a plane in KSP-- i.e. I didn't try for 20000m as it probably wouldn't do well. The maximum cruise altitude is just over 40,000 feet. Why do small African island nations perform better than African continental nations, considering democracy and human development? How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. - but they were talking about having two intakes/engine. - Spamming airintakes didn't help. 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. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 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. And it's stock, unfortunately. Thanks for asking this, I've been struggling with the same problem in career mode. Build a plane or rocket for Kerbal high altitudes, We've added a "Necessary cookies only" option to the cookie consent popup, Screenshot of the Week #85 [Submissions Closed - Vote Now!]. Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. 1Altitude requirement 2Orbit 3Speed, range, and altitude 4Flight duration 5Flight profiles 5.1Ballistic missiles 5.2Tourist flights 5.3Scientific experiments 5.4Sub-orbital transportation 6Notable uncrewed sub-orbital spaceflights 7Crewed sub-orbital spaceflights 8Future of crewed sub-orbital spaceflight 9See also 10References Long distance airplane flight tips? - Kerbal Space Program Forums Why do many companies reject expired SSL certificates as bugs in bug bounties? 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. The more successful the flights, the more successful the space program is. 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. Will post my results. List of altitude levels? - Forums - Kerbal Space Program Forums high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 600+ m/s) and low altitudes (e.g. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. Anyway thanks in advance. Which lets you go faster, which lets you climb higher. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. You can post now and register later. surface of jool. If you nudge your wing's angle up slightly with rotate tool then it'll move your prograde closer to your direction of flight and significantly reduce drag. Aircraft can be very temperamental to fly, especially on the keyboard. 3x06: I design a new, high altitude, jet to collect high. Though I'm still working on learning to be better at space planes. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Basically you just need to fiddle with it and try some test flights. "Whiplash" Turbojet. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

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. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. Kerbal Space Program ( KSP) is a space flight simulation video game developed by Mexican developer Squad for Linux, OS X, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. 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. If it's below the cross-hairs, you need a little more AoA. Yes. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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. What are the altitudes for the various altitude record contracts? Powered by Invision Community. Ok, the panther engine is still not good enough. It will be expensive and time consuming. 20 votes, 21 comments. Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane Do you know how many intakes/turbojet are needed to run in the regime you described? 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. Air Flow + max. As you found out, it basically konks out at 15km. even stranger is that the surface is textured. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! I looked into the .cfg files and there are no special properties allocated to them. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. But you'll need to unlock: Which cost 300 science. In addition to the traditional giant tube of explosions that flings things up high approach, Kerbal Space Program includes a very useful piece of equipment that became quite popular in the 20th century: wings.. 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. TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki 2022 Take-Two Interactive Software, Inc. 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'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Note that KSP planes get one substantial speed benefit that's much more pronounced than IRL aircraft, due to the freakishly small planet sizes: they're actually flying at a large fraction of orbital velocity. But a rockets can do it. It has two modes: The first, Dry mode, is similar to that of the J-33 "Wheesley" Basic Jet Engine, with a bit more thrust. Your link has been automatically embedded. : : . You will find that when you're flying around, will always be slightly below the crosshairs on the navball. 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. First is thrust; the higher you get, the lower the thrust your engines deliver. But since when do Kerbals wait for ideal conditions? KSP - High Altitude Aircraft - YouTube KSP Career: Episode 13 - High Altitude Surveys - YouTube Laythe - Kerbal Space Program Wiki Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. 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. More air is better. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Here's my example of dealing with the situation. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Planes in Space. 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. I've been finding it difficult to build a jet that can fly over 15km alt. 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. Note: Your post will require moderator approval before it will be visible. The U-2 is probably the highest altitude aircraft still flying. 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 . Very cool. 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. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Or you need to put a little bit of angle of incidence in your wings, which will reduce drag since you don't have to pitch the entire plane up, but will be stuck at a fixed angle meaning you'll have to pitch up or down anyway during certain phases of the flight that the plane isn't optimised for. Ksp engine altitudes : r/KerbalSpaceProgram - reddit 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. With only panthers unlocked I might add. Can't remember where I saw/read about it - Scott Manley maybe? 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. A destructible memorial to the old Mk. Rockets aren t the only way to get to space. So that means that even if you are inside the atmosphere but still orbital (such as during aerobraking), your science will not count as "Inside the atmosphere", For example, orbiting Kerbin above 250km altitude, your science is counted as "In Space High over Kerbin." The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. 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)? What plane in existence can fly at the highest altitude, and - Quora Evidence. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Please consider starting a new thread rather than reviving this one. Your link has been automatically embedded. However, I've failed to build a vehicle to achieve this (without a hundred retries). 2022 Take-Two Interactive Software, Inc. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs principle. When I say ", You know you've nailed it correctly if, when you're in level flight, your. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. I don't have that other stuff yet. Tutorial: Making the AI fly | BDArmory Wikia | Fandom Connect and share knowledge within a single location that is structured and easy to search. 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. I have enough patience to do the slow flying, but is it horribly inefficient? Note: Your post will require moderator approval before it will be visible. AoA and G-force moderation. Clear editor. 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!). . You can post now and register later. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. The main body is a fuel tank with a Swivel engine at the end. Either of the two speeds are to be avoided. 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.
