They will someday, but they don't now. What altitude and speed should I go? Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) 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. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Don't worry about Isp. The easiest "default" way to build a plane in KSP-- i.e. It will be expensive and time consuming. 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 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. Your answer got me in the right direction, though I ended up with a different design (see my own answer). Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. 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. I am currently designing a mission that will involve several very long distance plane flights. That's all true, but just read the OP: hypersonic appears to be completely out of the question. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Aircraft can be very temperamental to fly, especially on the keyboard. The longest flight got them down to a little more than half full. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. 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 use FAR these days, which basically means completely replacing every spaceplane and rocket you ever designed to account for its much more realistic aerodynamics. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. 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. As said above, the Wheesley is specifically designed as a low altitude engine. It's Kerbal Space Program v.22! its rather flat but its a solid surface. 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." Because when your engine has to take in air forcefully it automatically means there isn't enough surrounding your engine and that again means that air density and therefor air resistance must be pretty low too. Upload or insert images from URL. Note: Your post will require moderator approval before it will be visible. @SaintWacko's advice is probably the most practical. Display as a link instead, 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!). Whiplash is the engine you would want to use on a plane meant to go 20km.

I've since shaved that down more but that was by going even higher and even faster). I should perhaps start trying out NEAR to get ready of 0.90, though. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Paste as plain text instead, If you upgrade to the panther (or get one on a contract) that engine can get you much higher. 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. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. If it's above the cross-hairs, you need a little less. Your link has been automatically embedded. But you'll need to unlock: High Altitude Flight Which cost 300 science. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. 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. 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. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). Exorcet's Content - Kerbal Space Program Forums Trying to do something without the right part is long and difficult path. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. At about 400-500m/s (~15km), the two engines are even. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. With only panthers unlocked I might add. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. 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. If you have an account, sign in now to post with your account. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. 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. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". 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?). surface of jool. New comments cannot be posted and votes cannot be cast. High altitude planes - Kerbal Space Program Forums Your link has been automatically embedded. 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. Display as a link instead, Thats my problem right now. Build a plane or rocket for Kerbal high altitudes - Arqade Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Cookie Notice You may be correct and that 3 engine plane is a lemon. I don't have that cockpit in my career game yet, but maybe it will work with the other one. with a thrust vectoring range of only 3 degrees. What am I doing wrong here in the PlotLegends specification. 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. Now I have a plane that will fly around the world at an altitude of the low-20s. Clear editor. This way control surface max deflection can be programmed by an aircraft designer to make . Not only does it conk out at high altitudes, but also it conks out at high speeds, and you need to be able to go fast to fly up high. Please consider starting a new thread rather than reviving this one. KSP also tends to have very harsh induced drag if angle of attack gets too high. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. 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 It flames out at 25,000. Pasted as rich text. Planes in Space. The SR-71 could probably fly higher, but it isn't flying any more. This means that the only thing that decides wheter your engines run efficient is determined by how much thrust they produce (opt. 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. high-2 A Screenshot of Kerbal Space Program 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. I'd almost expect it to work better in stock since infini-gliders can be done. 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 below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. 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. What are the minimum altitudes for each warp level? How do I align things in the following tabular environment? The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. 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. 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. Hello there. 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 looked into the .cfg files and there are no special properties allocated to them. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. 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). Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Yes. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Create an account to follow your favorite communities and start taking part in conversations. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. What are the altitudes for the various altitude record contracts? I've added more engines, more intakes to no avail. Thanks. Should i add a larger wing area for higher lift? Any of my search term words; All of my search term words; Find results in. Paste as plain text instead, Pasted as rich text. No, I think it's correct, unless I've got a brain fart going, here. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Tutorial: Making the AI fly | BDArmory Wikia | Fandom Laythe - Kerbal Space Program Wiki Really. Upload or insert images from URL. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have. How do i build a high altitude plane? : r/KerbalSpaceProgram - reddit Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Airplane Plus on SpaceDock This works, but it's not optimal. You can spin around the whole world on just fumes. How can this new ban on drag possibly be considered constitutional? You arent doing anything wrong. But a rockets can do it. KSP Career: Episode 13 - High Altitude Surveys - YouTube
