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. 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. Will post my results. You need to do it with what you've got. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). You can post now and register later. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. I'm trying to build a high altitude plane and have found out that the rules are different. 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. 3x06: I design a new, high altitude, jet to collect high atmospheric science. It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. They will someday, but they don't now. Dedicated to the growth and advancement of amateur rocket scientists! 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. surface of jool. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Hello there. Your link has been automatically embedded. The easiest "default" way to build a plane in KSP-- i.e. 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.

You cannot paste images directly. i dont know what kind of range youre looking for but i would make a significantly smaller plane. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. First is thrust; the higher you get, the lower the thrust your engines deliver. 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. Range with this method is pretty short due to drag. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. But you'll need to unlock: High Altitude Flight Which cost 300 science. Incidentally, for these speeds and altitudes, ordinary jets are the better choice. 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 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. Thanks for asking this, I've been struggling with the same problem in career mode. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Welcome to the forums, ZDW. I've since shaved that down more but that was by going even higher and even faster). Evidence. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. It is stable but can not maintain altitude. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. The other one I stay around 6000 meters. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. As long as the engine gets enough air it will work at proper efficiency. Paste as plain text instead, - Spamming airintakes didn't help.

Thanks. 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. Even up there the plane acts squirrely. How do I align things in the following tabular environment? Your link has been automatically embedded. edited 6 yr. ago.

A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. You are simply running out of atmosphere (i.e. Cookie Notice 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? - Insane TWR didn't help. Jets drop thrust at higher altitude and speed, but also drop . This way control surface max deflection can be programmed by an aircraft designer to make . Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. These are the building blocks of solid spaceplane design!Subscribe! If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). In the stock atmosphere, the benefits of moving faster outweigh almost everything else. As has been said, ISP is nothing to worry about. You cannot paste images directly. Create an account to follow your favorite communities and start taking part in conversations. 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. 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 second, Wet mode, uses the afterburner to produce thrust almost equal to the J-X4 "Whiplash" Turbo Ramjet Engine, but at a considerably reduced fuel efficiency.

When I say ", You know you've nailed it correctly if, when you're in level flight, your. It only takes a minute to sign up. This thread is quite old. 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. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. As said above, the Wheesley is specifically designed as a low altitude engine. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. I was hoping that the new intakes would give it the added altitude. KSP also tends to have very harsh induced drag if angle of attack gets too high. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift.
