I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. More air is better. Personally, I don't enjoy survey contracts on Kerbin. 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. I was hoping that the new intakes would give it the added altitude. 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. The sweet spot for the upper atmo engines, I find, is between 10k and 12k. Your previous content has been restored. All rights reserved. Have you checked out the wiki yet? Your link has been automatically embedded. 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. 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. Display as a link instead, This can make it a good alternative for when you want something that can be controllable and doesn't need excessive heat shielding, but still need to be able to go incredibly fast if necessary, at the expense of increased fuel consumption. 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 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). Upload or insert images from URL. It flames out at 25,000. Yes. This tutorial will cover designing and flying a plane that can soar at high altitudes! In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Building a High Altitude Jet | Stream pt. Ep. Mounting a time-limited rescue mission for kerbal inbound to Kerbin.

For more information, please see our The main body is a fuel tank with a Swivel engine at the end. The other one I stay around 6000 meters. Sideslip handling. How do you get out of a corner when plotting yourself into a corner. Highest and fastest possible is best. 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. 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. Using Kolmogorov complexity to measure difficulty of problems? Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Your previous content has been restored. If it's above the cross-hairs, you need a little less. I checked the wiki before I wrote my question, it seems I overread this paragraph Something that I think has become less clear since someone updated the wiki. However, I've failed to build a vehicle to achieve this (without a hundred retries). rev2023.3.3.43278. Put a couple of radial mount parachutes just above the com and add a reaction wheel. Really. 20 votes, 21 comments. It is stable but can not maintain altitude. Double your speed, you need twice as much fuel. Air temperatures vary with latitude and time of day. 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. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. This thread is quite old. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. 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. Note: Your post will require moderator approval before it will be visible. Fighting oscillations. The more successful the flights, the more successful the space program is. Press question mark to learn the rest of the keyboard shortcuts. I followed a similar strategy. 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!]. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Content titles and body; Content titles only - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Should i add a larger wing area for higher lift? Why is there a voltage on my HDMI and coaxial cables? high-2 A Screenshot of Kerbal Space Program Anyway thanks in advance. Grichman's answer got me in the right direction. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. To get higher with the low tech jet engines, you need rocket assist. Is there a single-word adjective for "having exceptionally strong moral principles"? lost birth certificate near berlin; ksp high altitude plane. How can this new ban on drag possibly be considered constitutional? Your link has been automatically embedded. 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." Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. 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 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). Listen to this guy, don't go much farther above 15000 with high altitude engines. All other versions are slower and lower and unstable in turns. @SaintWacko's advice is probably the most practical. 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. 2.) So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. It was meant for low altitude flight. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. Either of the two speeds are to be avoided. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Pasted as rich text. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate surface of jool. Imagine that first plane but with the bubble cockpit and the old style round intakes. Paste as plain text instead, - "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. There is a very close tolerance to the two speeds. 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. This way control surface max deflection can be programmed by an aircraft designer to make . 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). You can do that by right-clicking the engine and clicking "Toggle Mode." Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. You cannot paste images directly. Your decreased flight time means you probably won't make it to your location. Clear editor. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. Building a rocket to fly vertical seems to be nearly impossible, in the atmosphere they tend to become unstable (or maybe I missed a trick?). i dont know what kind of range youre looking for but i would make a significantly smaller plane. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . But maybe your patience? . You can post now and register later. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. 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. 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. Kerbal Space Program Jool Landing Youtube. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. Thats my problem right now. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. I wasn't expecting so many excellent answers! 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. The high performance engine for me performs pretty good till about 15000 meter. Proceed with caution. What am I doing wrong here in the PlotLegends specification. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. Is it correct to use "the" before "materials used in making buildings are"? 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.. Your answer got me in the right direction, though I ended up with a different design (see my own answer). http://kerbalspaceprogram.com, Press J to jump to the feed. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. I have enough patience to do the slow flying, but is it horribly inefficient? 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. Hopefully this will be helpful to you. 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. even stranger is that the surface is textured. 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. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. I've been finding it difficult to build a jet that can fly over 15km alt. Jets drop thrust at higher altitude and speed, but also drop . 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. Thanks for the help! 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. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 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. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. This is the first version. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. a screenshot of kerbal space program 2. by: lord bird. 3x06: I design a new, high altitude, jet to collect high atmospheric science. 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. and our You need to do it with what you've got. 2022 Take-Two Interactive Software, Inc. - Spamming airintakes didn't help. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. - "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. Why do small African island nations perform better than African continental nations, considering democracy and human development? A destructible memorial to the old Mk. You could try combining the two. Is it even possible? It's Kerbal Space Program v.22! Are you using Stock or NEAR/FAR? The flight time won't be as long, but you'll be able to fly a "plane" above 18km. There are two factors to that: how thick the air is, how fast the ship is going. No, I think it's correct, unless I've got a brain fart going, here. I've added more engines, more intakes to no avail. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). principle. Or is it the same for all celestial bodies?

Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. As has been said, ISP is nothing to worry about. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Thanks for asking this, I've been struggling with the same problem in career mode.
