Which lets you go faster, which lets you climb higher. - "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. Will post my results. 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. rev2023.3.3.43278. 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. Is there a single-word adjective for "having exceptionally strong moral principles"? Laythe - Kerbal Space Program Wiki Your decreased flight time means you probably won't make it to your location. Very cool. Thanks for asking this, I've been struggling with the same problem in career mode. Thank you, I was able to reach up to 24km altitude with this design. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. My question is really about controllability. Your link has been automatically embedded. Early career high altitude observations question : r/KerbalAcademy Isn't that backwards snark? 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. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. its rather flat but its a solid surface. 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. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. 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. 2.) Grichman's answer got me in the right direction. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. These are the building blocks of solid spaceplane design!Subscribe! 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. As you found out, it basically konks out at 15km. So Pvt. 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. high altitude flight :: Kerbal Space Program General Discussions You are simply running out of atmosphere (i.e. Ok, the panther engine is still not good enough. What's the difference between a power rail and a signal line? 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. No, I think it's correct, unless I've got a brain fart going, here. Please consider starting a new thread rather than reviving this one. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. This way control surface max deflection can be programmed by an aircraft designer to make . I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. The more successful the flights, the more successful the space program is. 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. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. This causes the body of your plane to generate additional drag. Pasted as rich text. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Double your speed, you need twice as much fuel. Airplane Plus on SpaceDock Why not keep the engine for multi-stage rockets? - Space Exploration surface of jool. Kerbal Space Program - All Easter Eggs Guide 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. Beginner's Guide: Tips and Basics - Kerbal Space Program 2 Wiki Guide - IGN Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. 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..

Delta-v budget - Wikipedia Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. I have enough patience to do the slow flying, but is it horribly inefficient? Or is it the same for all celestial bodies? This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. 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 . Upload or insert images from URL. Don't rely on the efficiency indicator! I've since shaved that down more but that was by going even higher and even faster). and our This means it is better to have excessive amounts of oxygen than not to. Planes in Space. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . 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. This tutorial will cover designing and flying a plane that can soar at high altitudes! Anyway thanks in advance. "Whiplash" Turbojet. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. But my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. 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. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. More air is better. I wasn't expecting so many excellent answers! Even up there the plane acts squirrely. Air Flow + max. I don't have that cockpit in my career game yet, but maybe it will work with the other one. I've been finding it difficult to build a jet that can fly over 15km alt. 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. 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 I'd almost expect it to work better in stock since infini-gliders can be done. This is my current best hi alt plane. High altitude (~20km) possible with normal plane engines? 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. Of course, this thing has very limited range, speed and acceleration because of the extra weight. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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. Spaceplane - Wikipedia The other one I stay around 6000 meters. Something that I think has become less clear since someone updated the wiki. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. 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. But maybe your patience? 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. All trademarks are property of their respective owners in the US and other countries. Highest and fastest possible is best. high-2 A Screenshot of Kerbal Space Program 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. Trying to do something without the right part is long and difficult path. 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. Paste as plain text instead, Create an account to follow your favorite communities and start taking part in conversations. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. Main goals: Auto-trimming. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Planes and Altitude differences. :: Kerbal Space Program General Its an approximation missing someelements. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. You can spin around the whole world on just fumes. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. The Kerbal Space Program subreddit. 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. At altitude the nose goes up and down until it goes out of control. 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. It may work with stock too, I just don't know. Fighting oscillations. If you enter the Mun's SOI, it immediately counts as "In Space High over Mun" until you get below 60km Mun altitude. The most efficient way is, of course, to make a high altitude (or space) plane. Kerbal Space Program Jool Landing Youtube. Pasted as rich text. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

Here's my example of dealing with the situation. 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. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Designing a High Altitude Jet | KSP: Making Space Home Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. 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). The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Is it even possible? I generally don't fuss with AoI unless I'm making a long range cruiser. Press question mark to learn the rest of the keyboard shortcuts. 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? If you have an account, sign in now to post with your account. I didn't try for 20000m as it probably wouldn't do well. June 3, 2022 . I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. What are the minimum altitudes for each warp level? And it's stock, unfortunately. I should perhaps start trying out NEAR to get ready of 0.90, though. 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). Does a plane consume more fuel if it flies at higher altitudes? - "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. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. This thread is quite old. Do plugins for Kerbal Space Program work on unix? You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Note: Your post will require moderator approval before it will be visible. If it's below the cross-hairs, you need a little more AoA. Ksp engine altitudes : r/KerbalSpaceProgram - reddit Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. 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)? 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. It is stable but can not maintain altitude. Then it is "In Space Low over Mun.".

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. 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.
