There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. 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. Don't worry about Isp. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. a screenshot of kerbal space program 2. by: lord bird. So I've created those two planes, both with weasley turbofan engine: This is your problem-- as folks have pointed out, it's not a high-altitude engine. FBW uses three controllers - pitch, roll and yaw. June 3, 2022 . Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. 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. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. The more successful the flights, the more successful the space program is. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. First is thrust; the higher you get, the lower the thrust your engines deliver. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. If it's above the cross-hairs, you need a little less. Very cool. I don't have that other stuff yet. TLDR: You need parts you don't have to make a plane that flies that high. 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. 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)? 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. All trademarks are property of their respective owners in the US and other countries. Only the fuel tanks attached to rockets have any oxidiser in them. I don't recall if they model aspect ratio, but either way, the struts are murder and the delta wing has so much more wing that it'll still have more lift. So the faster you go the higher you can fly where there is less drag. Should i add a larger wing area for higher lift? 2022 Take-Two Interactive Software, Inc. The longest flight got them down to a little more than half full. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

Once I'm near or in the target area, I set the throttle to 0 and start the Swivel. Cookie Notice How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. To get higher with the low tech jet engines, you need rocket assist. Pasted as rich text. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. - "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. 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." as a rule of thumb they all lose thrust at higher altitudes and at high velocities. As has been said, ISP is nothing to worry about. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. This tutorial will cover designing and flying a plane that can soar at high altitudes! The maximum cruise altitude is just over 40,000 feet. That annoys me but I can't seem to get a design to make it work. Is it possible to get to an altitude of 16-20km with normal plane engines? 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. Ep. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. @SaintWacko's advice is probably the most practical. 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. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. You can halve the drag by climbing a bit less than 3500m. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Please consider starting a new thread rather than reviving this one. So if you want to make a plane go as fast as possible, you want to minimise both angle of attack and angle of incidence necessary to sustain level flight at your target speed and altitude. Its an approximation missing someelements. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. These are the building blocks of solid spaceplane design!Subscribe!

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.. If you have an account, sign in now to post with your account. How can I make money in the new career mode? You can post now and register later. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. The U-2's published maximum altitude is somewhere above 74,000 feet. First off as of .15.1 intakes don't do anything. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. You arent doing anything wrong. 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. Press question mark to learn the rest of the keyboard shortcuts. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. 3x06: I design a new, high altitude, jet to collect high atmospheric science. 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. Create an account to follow your favorite communities and start taking part in conversations. principle. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Clear editor. air) that high up. Put a couple of radial mount parachutes just above the com and add a reaction wheel. 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. Press question mark to learn the rest of the keyboard shortcuts. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). I've been finding it difficult to build a jet that can fly over 15km alt. Thanks. Pasted as rich text. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. So Pvt. It only takes a minute to sign up. 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. Even up there the plane acts squirrely. At altitude the nose goes up and down until it goes out of control. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate What are the units of measure used in Kerbal Space Program?

Remember that you need to have intakes somewhere in line with the engine to function at that altitude. 3.) 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. Thanks for the help! Upload or insert images from URL. It is designed to aid in player-controlled flight on generic (space)plane, providing a soft layer between user joystick\keyboard input and control surface outputs. The most efficient way is, of course, to make a high altitude (or space) plane. surface of jool. - Spamming airintakes didn't help. I start with the normal jet engines (which takes almost the complete runway). A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 2.) If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Any of my search term words; All of my search term words; Find results in. For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. 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. AoA and G-force moderation. 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. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Basically I can hit a target altitude of 20,000m but can not maintain it. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. Yes, although they have only been flown with nearly full tanks. Which is capable of high altitude, high speed flight. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. 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.

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. Either of the two speeds are to be avoided. You can do that by right-clicking the engine and clicking "Toggle Mode." 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. This makes jets built using this engine considerably more maneuverable. You could try combining the two. This causes the body of your plane to generate additional drag. edited 6 yr. ago. Basically you just need to fiddle with it and try some test flights. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. 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). Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. Why do small African island nations perform better than African continental nations, considering democracy and human development? I'm trying to build a high altitude plane and have found out that the rules are different. Is there a single-word adjective for "having exceptionally strong moral principles"? Or try using SRBs instead. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series.
