All the weight is pushed on the middle and it can't pull up. Then you want to put something called a "Small Circular Intake" on the front of the tank, and a "J-20 Juno" engine on the back of the tank. Display as a link instead, I made a KSP replica of the Horten Ho 229 while trying to make a short takeoff plane.If you have any questions or suggestions, let me know in the comments.My. I scoured the entire web for a solution, but found no working solution or at least dont work every time. If you're tired of big rockets that use tons of fuel and disintegrate in the atmosphere when coming back to Kerbin, this tutorial is perfect for you! For more information, please see our I was wrong. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Basic_Plane_Design&oldid=97453, In the front of the plane - In this position, the control surfaces are also known as , In the back of the plane, on the tail - The most usual position; usually, close to the rudder. Your previous content has been restored. (Idea is moot, if you haven't unlocked them yet.) When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. Plane bouncing on takeoff - Kerbal Space Program Forums Press question mark to learn the rest of the keyboard shortcuts. Easier just to bring the rear wheels closer as well as a in line reacton wheel. If your spaceplane is difficult to land when full of fuel but easy to land when empty, then it may be helpful to burn off or transfer out most of the excess fuel before landing to make the aircraft lighter. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Need to move them up. It is usually placed back because it can be placed further back than it is possible in the front (if it is placed in the front, it can obstruct the view of the pilot, which is undesired) as well as making the plane unstable (by the same effect that you would get if the center of lift (horizontal lifting surfaces) were in front of the center of mass, but with vertical surfaces). If you have an account, sign in now to post with your account. They are able to operate at higher altitudes and can even continue operating in a vacuum by switching to a rocket mode. Note: Your post will require moderator approval before it will be visible. Real planes do this as well. (However, it must be noted that it is bad practice to use ailerons as elevators since it makes it hard to control the aircraft), The rudder moves the tip of the plane left and right; it is rarely used, since it is hard to put it both up and down due to the possibility of hitting the ground. If you have trouble pitching up enough to land at a reasonable speed, you can increase your maneuverability by toggling your flaps, canards and ailerons to greater than 100% control authority. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. This material may not be published, broadcast, rewritten, or redistributed. Kerbal Space Program 2's simulation is a lot more in-depth than its predecessor, where it was feasible for any wannabe Goddard to punch through the atmosphere with overwhelming thrust. They sometimes coincide with ailerons on some, more space-economical, aircraft. Congratulations! To recover the most value from your spaceplane, you should try to land on the runway at the Space Center (this tutorial, although it has been written for spacecraft and not spaceplanes, is a great help). For all your gaming related, space exploration needs. [KSP] - Heavy Seaplane Take-off, Water-landing and Re-take-off! Here is your convenient solution to this problem! I shouldn't have placed landing gears on the fuselage, I found that placing landing gears on flat surfaces like wings make landing gears a lot more stable. A good example of this is at the KSC runway when landing on a 90 degree bearing. I dont really need 200m/s for take off. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 spaceplane parts for the engines. So the answer is: in the SPH, click on your front gear, set the spring to .5 and set the damper to .5 -- then save it and give it another shot at launching. You can post now and register later. Basic structure Firstly you're going to want to make a short fuselage. Firstly, inadequate air intakes for the number and type of engines you're using (causing some engines to shut down before others). (Sorry For Poor Image Quality) : r/KerbalAcademy 385 votes, 49 comments. Why is it doing this? How to make aircraft take off - Kerbal Space Program Forums Tutorial:Basic SSTO Design - Kerbal Space Program Wiki . I moved the back landing gear to right underneath the COM. the I place on the wing and attach landing gear on those, it sometimes takes a few tries to find the right spot but well worth it. To slow down faster, you can increase the braking strength of your rear wheels. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. I have created a score of other aircrafts with different designs but deleted them because they didnt work even on the runway. - SF. Mechjeb Spaceplane Guidance : r/KerbalSpaceProgram - reddit Here is the best aircraft I have created to date: Jet Aircraft. Because of how small Kerbin is and how high its gravity is, a perfectly flat surface just north of the equator will cause planes taking off to bias to the right of the runway, as if they were rolling downhill. In an aircraft with two or more engines, this can potentially cause you to enter a flat spin which can be unrecoverable if your center of mass is behind your center of lift. It is also advisable to add some control surfaces to your plane to have some control in the atmosphere: you can manually add them to the wings or choose winglets with effective control surfaces, like the Standard Canard. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. If you have seen the examples above, I have planes that have angled landing gear and they work perfectly, yet some planes with straight landing gears don't. All of them had one thing in common though. If the problem has to do with lift then travelling very slowly, possibly even slower than that, should counteract the effects of lift and you won't drift nearly as much. This is also the same reason why planes start rolling toward the middle of the runway; because both ends of the runway are further from . I have found a solution to my problem. my planes keep flipping backwards on take off . Your very own tutorial.). as Shkeec said check gear check gear check gear. It doesn't really matter if you angle them or not, there is not a single configuration for the wheels that can work on all plane parts. Note that a Wheesley or Goliath engine can reverse its thrust to allow rapid deceleration during landing, but these are not recommended for a spaceplane due to being unreasonably heavy and inducing excessive drag when attempting to transition to orbital velocities. If you can give a craft file and a mod list I could take a look. When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. All you need to do is add landing gear (one right before the cockpit, and two on the tips or middle of the wings), and you're done! 5.whether the body you anchor the landing gears to are firm. LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. My plane tends to wobble on the runway with the stock game so i decided to download FAR, but the problem still persists. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. Your wheels should now have 0 degree angle between them, meaning they are both. 3. angle of the wheels. Saves a lot of headache in wheels placement. Does your plane never pull up taking off? I have been building - reddit Be warned that if you do not provide sufficient air intakes for the engines you've placed, you may find that some of your engines shut down before others. #2 DaSkippa Mar 14, 2014 @ 2:56am as Shkeec said check gear check gear check gear. However, I want to place my wheels where i want to and not only on X parallel surfaces. Then this tutorial is for you. As long as you're in space, your spaceplane won't differ from any spacecraft: you will probably want to add batteries and generators to prevent the command pod from running out of power. Take the large delta wings and place them on the aircraft. Is there a way to rectify this problem. For myself, it always was the position of landing gear in terms of pitch. Paste as plain text instead, That, combined with a Unity joint bug, makes your plane bounce. KSC's runway is slightly north of Kerbin's equator and perfectly flat. KSP short takeoff plane test | Simple Horten Ho 229 replica Why does my plane roll left on takeoff : r/KerbalSpaceProgram - reddit Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. I removed them and it works fine now. If you forget to put an air intake on your airplane, don't worry! Try not to place your gears to wings, especially wingtips - if they wobble even slightly, your plane lose the balance. However it's huge size can make it tricky to take off from the runway without destroying the engine. An alternative is making sure you have complete control of the craft. If you've been able to successfully re-enter on previous low orbit test runs, you should be able to use this method to achieve similar rates of success once you've slowed down sufficiently. The FedEx plane pulled back up in time to avoid a collision. Ideally, you ought to test landing the spaceplane with full fuel tanks and with nearly empty fuel tanks prior to taking your spaceplane to orbit. This plane will be able to take off, travel somewhere, perform a crew report, and then land. For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. Everything looks perfectly symmetrical as far as I can tell. (For test purposes, all aircraft are not pitched up and SAS is turned off. Maybe ;making the tailwheel less stiff would help, too. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! Plane - Kerbal Space Program Wiki This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. A Mk1 Cockpit, two Mk 1 Liquid Fuel Tanks, and then cap the back with a round nose cone (use the A/D keys to rotate it as necessary). I'm making sure that I keep trying to get it up but it just wont go! Paste as plain text instead, FOX 56 News Video More Videos This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. An altitude set to 18,000 meters tops off at 19,000 meters and drops to 15,700 meters . Note that the lift rating does not mean that the wings will automatically lift a spaceplane into the air when it's moving forward. Heavy Cargo Space Plane SSTO Download. Your wings provide the lift, and they cant provide lift if your wheels are too far back because then your base is to stable and the craft wont pivot upwards. Depending on which surface you place them on, they might not be parallel to the axis in which case. They could go up to 120 m/s on the runway and still not lift up. Suggest a Correction Copyright 2023 Nexstar Media Inc. All rights reserved. The tutorial below explains everything very well. The Mk1 fuselage parts only tolerate up to 2000K, while Mk2 fuselages tolerate up to 2500K, and Mk3 fuselages tolerate up to 2700K. Having said all that, these are the issues you must contend with. Install S5 moon rocket By lightbreaker_64. Note that when your jet engines shut down simultaneously while climbing in otherwise normal flight, it is generally due to a lack of pressure from the altitude you're flying at. If that's not an option, you can still recover some value by landing at any suitable flat place on Kerbin. At that point, the plane could potentially start spinning around as a result of losing the benefit of the gimbal control of the engine.
