Watch out for your SAS if you're running batteries without a jet for a long time. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. 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)? Press question mark to learn the rest of the keyboard shortcuts. Please consider starting a new thread rather than reviving this one. These designs are great for getting around Kerbin quickly, but without going orbital. "Whiplash" Turbojet. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. Cookie Notice Another problem is jet engines stealing fuel from the rockets' tanks - you may want to pump the fuel manually (requires an R&D centre upgrade) or add some pipes between them. It flames out at 25,000. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Is anywhere a list of the altitude levels (I don't know a better term) available? Paste as plain text instead,
Plane - Kerbal Space Program Wiki You are just about at maximum speed and at the same time very close to stall speed. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). June 3, 2022 . At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. Press J to jump to the feed. There's basically three ways to do that: lifting surfaces, thrust, and orbiting. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k.
Why not keep the engine for multi-stage rockets? - Space Exploration 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Third, which I haven't given a good try, would be a carefully-timed deorbit maneuver so you come down through your desired location as you fall from space. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Most SSTO space planes would be able to accomplish this easily. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. 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. 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. To get higher with the low tech jet engines, you need rocket assist. Air temperatures vary with latitude and time of day.
CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General 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. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. All other versions are slower and lower and unstable in turns. 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. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. 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. No, I think it's correct, unless I've got a brain fart going, here. Your decreased flight time means you probably won't make it to your location. Really. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ 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. 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 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. 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). Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. First is thrust; the higher you get, the lower the thrust your engines deliver. Create an account to follow your favorite communities and start taking part in conversations. 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. 2.) 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. Clear editor. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. If it's below the cross-hairs, you need a little more AoA. Display as a link instead, Note: Your post will require moderator approval before it will be visible. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Basically you just need to fiddle with it and try some test flights.
TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki As said above, the Wheesley is specifically designed as a low altitude engine. 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. I didn't try for 20000m as it probably wouldn't do well. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Challenges
Personally, I don't enjoy survey contracts on Kerbin. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Something that I think has become less clear since someone updated the wiki. These are the building blocks of solid spaceplane design!Subscribe! You can spin around the whole world on just fumes. Is there a single-word adjective for "having exceptionally strong moral principles"? Proceed with caution. and our 3.) 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. You can go above 20km with the J-404 Panther. This works, but it's not optimal. Press question mark to learn the rest of the keyboard shortcuts. Upload or insert images from URL. 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). But you'll need to unlock: Which cost 300 science. Evidence. 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.. 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 . (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. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. 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. 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. I start with the normal jet engines (which takes almost the complete runway). Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. The U-2 is probably the highest altitude aircraft still flying.
Exorcet's Content - Kerbal Space Program Forums Create an account to follow your favorite communities and start taking part in conversations. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. Any advices for building a vehicle for this task? What are the minimum altitudes for each warp level? 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. It may work with stock too, I just don't know. alternatively, combine a liquid fuel rocket into your plane. I'm trying to build a high altitude plane and have found out that the rules are different. Which is capable of high altitude, high speed flight. 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. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. Even up there the plane acts squirrely.
Kerbal Space Program - Wikipedia So the faster you go the higher you can fly where there is less drag. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast.
Landing On Laythe Moon Of Jool Kerbal Space Program Youtube : : . 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. Display as a link instead, Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. surface of jool. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. My question is really about controllability. 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. Knowing how to design these types of planes make jumping in to SSTO design very easy as there are only a few minor changes that need to be made.Music Credits:1st Song: \"Elephants\" - YouTube Audio Library2nd Song: \"Hot Heat\" - YouTube Audio Library3rd Song: \"Echoes\" - Kasbo - https://soundcloud.com/k-sboWhat game is this?
Kerbin | Kerbal Space Program Wiki | Fandom Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) List of altitude levels? - Forums - Kerbal Space Program Forums .
Best altitude to fly a plane? - Kerbal Space Program - GameFAQs The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. So Pvt. even stranger is that the surface is textured. Let me.
Sub-orbital spaceflight - Wikipedia Powered by Invision Community. This thread is quite old. Clear editor. Its an approximation missing someelements. The drag differential is because your long-wing layout is using a bunch of struts, and the reason your delta-wing has a higher ceiling is because it has more wing area to provide lift. The Panther engine can hold 19,000 steady and oscillates around 20,000. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. I should perhaps start trying out NEAR to get ready of 0.90, though. - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Anyway thanks in advance. principle. its rather flat but its a solid surface. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode.
Delta-v budget - Wikipedia I'd almost expect it to work better in stock since infini-gliders can be done. The longest flight got them down to a little more than half full. What am I doing wrong here in the PlotLegends specification. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. You arent doing anything wrong. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 1 Pod outside the level 3 VAB. Your link has been automatically embedded. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. The easiest "default" way to build a plane in KSP-- i.e.
Please consider starting a new thread rather than reviving this one. Or try using SRBs instead. 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). But a rockets can do it. Thats my problem right now. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. There are two factors to that: how thick the air is, how fast the ship is going. 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. 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. Content titles and body; Content titles only Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. How do I align things in the following tabular environment? I'm going to try adding a small solid fuel rocket engine toned down to get the initial height then dump it, as well as check into that high end gear mentioned. I have enough patience to do the slow flying, but is it horribly inefficient? 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.
Build a plane or rocket for Kerbal high altitudes - Arqade FBW uses three controllers - pitch, roll and yaw. Is it possible to get to an altitude of 16-20km with normal plane engines? Double your speed, you need twice as much fuel. 20 votes, 21 comments. But maybe your patience? Don't be too surprised if KSP's aero model breaks down in edge cases. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. The maximum cruise altitude is just over 40,000 feet. Chapter 4. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. You could try combining the two. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Hello there. - Insane TWR didn't help. 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.
ksp high altitude plane - digitalidentityorganization.com *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. Ok, the panther engine is still not good enough. 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. 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 I wasn't expecting so many excellent answers! Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! Very cool. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. The Kerbal Space Program subreddit. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode.
Airplane Plus on SpaceDock 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? Highest and fastest possible is best. 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. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. 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. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. 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? That's because wings need to have some AoA to the airstream in order to generate much lift. 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. The SR-71 could probably fly higher, but it isn't flying any more. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Why is there a voltage on my HDMI and coaxial cables? 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. 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. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet.
Jet engine - Kerbal Space Program Wiki But you'll need to unlock: High Altitude Flight Which cost 300 science. Please consider starting a new thread rather than reviving this one. Turbojets are so ridiculously efficient that it doesn't really matter. 1.) 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. 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. Yes, although they have only been flown with nearly full tanks. 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. 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun The most efficient way is, of course, to make a high altitude (or space) plane. Connect and share knowledge within a single location that is structured and easy to search. The best answers are voted up and rise to the top, Not the answer you're looking for? Do plugins for Kerbal Space Program work on unix? So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. I followed a similar strategy. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. If not, please explain why, which I know you have no problem doing!
What plane in existence can fly at the highest altitude, and - Quora Incidentally, for these speeds and altitudes, ordinary jets are the better choice. As long as the engine gets enough air it will work at proper efficiency. Thank you, I was able to reach up to 24km altitude with this design. - "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. Pasted as rich text. 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?). Upload or insert images from URL. You can halve the drag by climbing a bit less than 3500m. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane.
