ksp high altitude plane

(Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. 2022 Take-Two Interactive Software, Inc. Whiplash is the engine you would want to use on a plane meant to go 20km. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. Connect and share knowledge within a single location that is structured and easy to search. By climbing, you reduce drag, exponentially with altitude. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. . 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.

Should i add a larger wing area for higher lift? 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). Ok, the panther engine is still not good enough. Why that? 2022 Take-Two Interactive Software, Inc. I'm trying to build a high altitude plane and have found out that the rules are different. Please consider starting a new thread rather than reviving this one. Now I have a plane that will fly around the world at an altitude of the low-20s. Your decreased flight time means you probably won't make it to your location. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Is it correct to use "the" before "materials used in making buildings are"? 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. All trademarks are property of their respective owners in the US and other countries. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. If it's below the cross-hairs, you need a little more AoA. Display as a link instead, The main body is a fuel tank with a Swivel engine at the end. Valve Corporation. Either of the two speeds are to be avoided. It is stable but can not maintain altitude. I would like to know which altitude I have to maintain for my experiments. Range with this method is pretty short due to drag. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Upload or insert images from URL. 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. All other versions are slower and lower and unstable in turns. Of course, this thing has very limited range, speed and acceleration because of the extra weight. The U-2's published maximum altitude is somewhere above 74,000 feet. How do I align things in the following tabular environment? 20 votes, 21 comments. Reddit and its partners use cookies and similar technologies to provide you with a better experience. alternatively, combine a liquid fuel rocket into your plane. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Kerbal Space Program 2 . 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. 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. 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. Here's Mr. Manley using it in his tutorial: @Pvt.Grichmann: I think it's at specific locations on Kerbin, not just anywhere above 18km. As has been said, ISP is nothing to worry about. But you'll need to unlock: High Altitude Flight Which cost 300 science. Most SSTO space planes would be able to accomplish this easily. Or about the same speed but 1000 m higher. 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). at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. Or is it the same for all celestial bodies? Mounting a time-limited rescue mission for kerbal inbound to Kerbin. 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. If you have an account, sign in now to post with your account. You need to do it with what you've got. : : . Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. 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. As said above, the Wheesley is specifically designed as a low altitude engine. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Thanks for asking this, I've been struggling with the same problem in career mode. For all your gaming related, space exploration needs. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. 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.. Fighting oscillations. If not, please explain why, which I know you have no problem doing! Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. And it's stock, unfortunately. To get higher with the low tech jet engines, you need rocket assist. 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. and our I should perhaps start trying out NEAR to get ready of 0.90, though. But since when do Kerbals wait for ideal conditions? Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

That annoys me but I can't seem to get a design to make it work. 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. 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 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). 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. TLDR: You need parts you don't have to make a plane that flies that high. Double your speed, you need twice as much fuel. This works, but it's not optimal. Listen to this guy, don't go much farther above 15000 with high altitude engines. Note: Your post will require moderator approval before it will be visible. This means it is better to have excessive amounts of oxygen than not to. Either finish the low-altitudes and then spend all your fuel on the high-altitude boost, or do the boost first and save a little fuel or try to hit the rest through unpowered gliding. Please consider starting a new thread rather than reviving this one. 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. 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. When I say ", You know you've nailed it correctly if, when you're in level flight, your. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. 2022 Take-Two Interactive Software, Inc.

That will unlock: 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. Dedicated to the growth and advancement of amateur rocket scientists! Press J to jump to the feed. Hello there. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Its an approximation missing someelements. 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. Will post my results. Press question mark to learn the rest of the keyboard shortcuts. First is thrust; the higher you get, the lower the thrust your engines deliver. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. 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. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Or try using SRBs instead. Building a High Altitude Jet | Stream pt. You'll notice that usually your prograde marker is slightly below your pitch. Your link has been automatically embedded. For more information, please see our Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! As long a you can fly faster, the lower density at altitude can be compensated for. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is it possible to get to an altitude of 16-20km with normal plane engines? Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. More air is better. If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. So the faster you go the higher you can fly where there is less drag. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. 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. The longest flight got them down to a little more than half full. At about 400-500m/s (~15km), the two engines are even. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Is it even possible? Note: Your post will require moderator approval before it will be visible. 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). I don't have that other stuff yet. 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. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). 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. 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. You can halve the drag by climbing a bit less than 3500m. - "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. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. This causes the body of your plane to generate additional drag. Have you checked out the wiki yet? However, I've failed to build a vehicle to achieve this (without a hundred retries). You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. Anyway thanks in advance. Originally posted by lord bird: yep thats right jool has a surface. 2.) Pasted as rich text. First off as of .15.1 intakes don't do anything. How do I install mods for Kerbal Space Program 1.1? New comments cannot be posted and votes cannot be cast. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Please consider starting a new thread rather than reviving this one. You may be correct and that 3 engine plane is a lemon. 2022 Take-Two Interactive Software, Inc. a screenshot of kerbal space program 2. by: lord bird. Evidence. 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. This is my current best hi alt plane. Isn't that backwards snark? 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. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Display as a link instead, 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. Any advices for building a vehicle for this task? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Thanks. Planes in Space. 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. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. 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. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 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. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. I don't have that cockpit in my career game yet, but maybe it will work with the other one. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. high-2 A Screenshot of Kerbal Space Program Turbojets are so ridiculously efficient that it doesn't really matter. its rather flat but its a solid surface. You cannot paste images directly. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. surface of jool. Create an account to follow your favorite communities and start taking part in conversations. I've been finding it difficult to build a jet that can fly over 15km alt. Been a while since I've flown stock*, but I've heard that, for maximum efficiency, you want one turbojet for every 7.5 tons, and about four ram intakes for each turbojet. 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. Welcome to the forums, ZDW. Arqade is a question and answer site for passionate videogamers on all platforms. Clear editor. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Don't worry about Isp. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. 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. edited 6 yr. ago. The returns are diminishing so eventually you will hit a ceiling. 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. Proceed with caution. Which is capable of high altitude, high speed flight. Your previous content has been restored. 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 a rule of thumb they all lose thrust at higher altitudes and at high velocities. Thats my problem right now. - but they were talking about having two intakes/engine. 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. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Jets drop thrust at higher altitude and speed, but also drop . In the stock atmosphere, the benefits of moving faster outweigh almost everything else. Even up there the plane acts squirrely. 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. The more successful the flights, the more successful the space program is. FBW uses three controllers - pitch, roll and yaw. The high performance engine for me performs pretty good till about 15000 meter. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). You could try combining the two. So Pvt. You arent doing anything wrong. 1.) That's because wings need to have some AoA to the airstream in order to generate much lift. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. 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. - Insane lift to weight didn't help.

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. Highest and fastest possible is best. 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. Designing a High Altitude Jet | KSP: Making Space Home Mike Aben 24.8K subscribers Join Subscribe 85 Share 3.4K views 1 year ago Ep. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. *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. It was meant for low altitude flight. I generally don't fuss with AoI unless I'm making a long range cruiser. You can post now and register later. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Contents 1 Usage 2 Construction 3 Categories 3.1 Airplane 3.2 Seaplane 3.3 Spaceplane 3.4 VTOL 3.5 Glider 3.6 Mothership 4 Operation 4.1 Flight records 5 Notes Usage principle. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. What are the units of measure used in Kerbal Space Program? ksp high altitude plane. (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. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. The best answers are voted up and rise to the top, Not the answer you're looking for? At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing. The Kerbal Space Program subreddit. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. 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.
