- "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. I'd almost expect it to work better in stock since infini-gliders can be done. You cannot paste images directly. So the faster you go the higher you can fly where there is less drag. The Panther engine can hold 19,000 steady and oscillates around 20,000. 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. Have you checked out the wiki yet? 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. They will someday, but they don't now. 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. 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. First is thrust; the higher you get, the lower the thrust your engines deliver. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. June 3, 2022 . Yes, although they have only been flown with nearly full tanks. I'm trying to build a high altitude plane and have found out that the rules are different. 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. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. Planes in Space. Originally posted by lord bird: yep thats right jool has a surface. Though I'm still working on learning to be better at space planes. 1.) You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. How do I install mods for Kerbal Space Program 1.1? I've added more engines, more intakes to no avail. http://kerbalspaceprogram.com, Press J to jump to the feed. even stranger is that the surface is textured. You can post now and register later. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. If you have an account, sign in now to post with your account. 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. I wasn't expecting so many excellent answers! Don't be too surprised if KSP's aero model breaks down in edge cases. Dedicated to the growth and advancement of amateur rocket scientists! 2022 Take-Two Interactive Software, Inc. Display as a link instead, But you'll need to unlock: High Altitude Flight Which cost 300 science. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. By climbing, you reduce drag, exponentially with altitude. You can go above 20km with the J-404 Panther. Should i add a larger wing area for higher lift? Of course, this thing has very limited range, speed and acceleration because of the extra weight. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. Or is it the same for all celestial bodies? Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes).

Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. You are just about at maximum speed and at the same time very close to stall speed. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. Ep. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. It's Kerbal Space Program v.22! Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. You can post now and register later. 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!). I looked into the .cfg files and there are no special properties allocated to them. Sideslip handling. I've since shaved that down more but that was by going even higher and even 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. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. 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. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. 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. 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. 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." Highest and fastest possible is best. Don't rely on the efficiency indicator! 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 other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Arqade is a question and answer site for passionate videogamers on all platforms. 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.. But since when do Kerbals wait for ideal conditions? The flight time won't be as long, but you'll be able to fly a "plane" above 18km. 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 How to tell which packages are held back due to phased updates. 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 The U-2 is probably the highest altitude aircraft still flying. Pvt. This thread is quite old. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. This is the first version. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 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. - "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. 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. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. 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. More air is better. Chapter 4. But maybe your patience? Double your speed, you need twice as much fuel. FAR is supposed to take aspect into account, but I'm not very experienced with it and cannot advice you as to how it works. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 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. surface of jool. 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. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. You cannot paste images directly. If it's below the cross-hairs, you need a little more AoA. I am currently designing a mission that will involve several very long distance plane flights. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Is it correct to use "the" before "materials used in making buildings are"? Your answer got me in the right direction, though I ended up with a different design (see my own answer). 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. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. There are two factors to that: how thick the air is, how fast the ship is going. Air temperatures vary with latitude and time of day. 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. Building a High Altitude Jet | Stream pt. You need to do it with what you've got. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Why do small African island nations perform better than African continental nations, considering democracy and human development? If you have an account, sign in now to post with your account. Let me share what I know about jet engines, speed, and efficiency. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Which is capable of high altitude, high speed flight. Note that you need to activate the afterburner ("Wet Mode") manually. Using Kolmogorov complexity to measure difficulty of problems? KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Only the fuel tanks attached to rockets have any oxidiser in them. 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. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Welcome to the forums. Trying to do something without the right part is long and difficult path. This makes jets built using this engine considerably more maneuverable. How do I align things in the following tabular environment? 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. Jets drop thrust at higher altitude and speed, but also drop . Cheers again fellas. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Can't remember where I saw/read about it - Scott Manley maybe? 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. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Main goals: Auto-trimming. - but they were talking about having two intakes/engine. So Pvt. First off as of .15.1 intakes don't do anything. Then it is "In Space Low over Mun.". Will post my results. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Thanks for the help! Yes. 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. All the information you could want to know about science, including the altitudes for each celestial body, and what altitudes a given experiment works on are available at: http://wiki.kerbalspaceprogram.com/wiki/Science. That annoys me but I can't seem to get a design to make it work. 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. The SR-71 could probably fly higher, but it isn't flying any more. 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. 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. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. Something that I think has become less clear since someone updated the wiki. Or about the same speed but 1000 m higher. For example, the RAPIER engine doesn't seem as the first choice as the "best" high altitude air-breathing engine but in long-distance and high-altitude challenges it is. Very cool. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Your previous content has been restored. Paste as plain text instead, So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less. Press question mark to learn the rest of the keyboard shortcuts. How do you get out of a corner when plotting yourself into a corner. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. If it's above the cross-hairs, you need a little less. Challenges That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Which lets you go faster, which lets you climb higher. 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. ksp high altitude plane. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Is anywhere a list of the altitude levels (I don't know a better term) available? 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. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. At altitude the nose goes up and down until it goes out of control. Don't worry about Isp. Your previous content has been restored. rev2023.3.3.43278. Ok, the panther engine is still not good enough. Please consider starting a new thread rather than reviving this one. Here's my example of dealing with the situation. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Watch out for your SAS if you're running batteries without a jet for a long time. Upload or insert images from URL. Evidence. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. And it's stock, unfortunately. Delta-V is the velocity change necessary to perform orbital maneuvers. Cookie Notice 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). I don't have that other stuff yet. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. All other versions are slower and lower and unstable in turns.
ksp high altitude plane
