This is most likely the standard jitterbugging problem. If your spaceplane is able to fly and land steadily at low speeds but just you're having difficulty slowing down as you approach the runway, try to reach your desired speed first and then approach the runway in almost level flight. Note that canards are somewhat more efficient than horizontal tail fins since canards provide an upward force with upward rotation, and downward force with downward rotation. What causes turbulence? | WOWK 13 News Easier just to bring the rear wheels closer as well as a in line reacton wheel. You cannot paste images directly. I found biggest cause of this as well as not being able to possibly correct is having sas on during takeoff, make sure that is off during take off and should find problem is less likely to occur, but I too struggle to make working space planes even when center of lift, mass, thrust are all as needed. Keep your nose pointed prograde as you descend through the atmosphere. Having said all that, these are the issues you must contend with. A good example of this is at the KSC runway when landing on a 90 degree bearing. Description: "Originally called the Cockpit-plus-two, the 5 seat "Cockatoo" is a second-generation command pod that provides both safety and comfort It is rumored to have enough room to pack several days of emergency snack rations and board games" Useful stats: As the description states this large command pod holds 5 kerbals Now stick a jet engine on the back, and don't forget to put an air intake or other air-sucking device (you can find them in aerodynamics) on the airplane. I have found a solution to my problem. Valve Corporation. 2. Beyond that, you're going to get some wobble once you get close to take off speed. Kerbal Space Program 2 - Overview and Tutorial for All the New Parts You can also angle the wings themselves slightly upwards (using WASDQE) in order to make them generate more lift when horizontal. The same principle applies here. While I am not a great plane builder there is a part in the structural (I think it is a pylon?) Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. Note: This tutorial was last updated for version 1.7.2. This can turn into a fatal scenario if the center of mass gets behind the center of lift and you enter a flat spin. This helps to keep the performance of your spaceplane stable with any amount of fuel. In vanilla KSP, wings have a predefined lift factor. (Yes, you personally, you lucky thing! Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. 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). Clear editor. You're going to have a bad time. A relatively low-drag alternative is to use an inverted cargo bay and some hydraulic cylinders with structural panels as a cargo elevator. Thanks for all the help. As you approach 35-50 km, your aircraft will most likely level itself out, at which point you can try aiming about five degrees above the horizon line. Cookie Notice I dunno why but this picture makes the one side look like it is tipped in but I know they are straight, I believe it just the angle that the picture was taken that is causing it to look like this. To avoid swerving on takeoff and landing, it is strongly recommended to turn off or reduce the strength of the front brake on your aircraft, as well as to reduce the friction control. You can either go with four "LY-O1 Fixed" or a tricycle of two LY-01 near the back and one "LY-05 Steerable" at the front; either is fine for now. They all had to use the runway drop to take off. Note: Some high-efficiency rocket engines lose most of their power and efficiency in low atmosphere. But I am still not sure if there are more reasons or perhaps it is just a physics bug which I am wasting my time on. This tutorial will help you with the basics of spaceplane flight, and will help you avoid the most common errors that could ruin your day as a spaceplane pilot! Plane - Kerbal Space Program Wiki 1. tilt of the plane. Here are a few pictures of it: Take a picture with center of mass and center of lift turned on. Any plane needs speed - so you need thrust (usually). 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 . Firstly you're going to want to make a short fuselage. wings, unless they're very well braced). Now for the engines. Quick context, I am a software engineer. If you can't slow down in time, you can simply flick your engines back on to take off and turn around for another try as you pass over the coast. A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. DO NOT ANGLE THEM! 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). Does your plane never pull up taking off? I have been building - reddit 4. my planes keep flipping backwards on take off . Besides the good advice others have given, I would also be very careful with that little tailwheel.

If you have a very short length of runway remaining and your parachutes can't slow you down fast enough, you'll be forced to cut the chutes and attempt a second landing without them. See the tutorial below. Real planes do this as well. Saves a lot of headache in wheels placement. I am accelerating it to over 200m/s on the runway just to test the stability of those wheels since the faster you go, the more likely the plane will wobble and flip on the runway. The FedEx plane pulled back up in time to avoid a collision. To slow down faster, you can increase the braking strength of your rear wheels. The issue is my plane rolls very sharply to the left any time I pitch up. 2022 Take-Two Interactive Software, Inc. These occur at their worst when your center of gravity is far ahead of your rear landing gears and you have a heavy plane at high speeds and a high angle of attack on landing, resulting in your front landing gear rapidly striking the runway after your rear landing gears touchdown. You probably won't have much luck landing the fuselage intact if your Mk3 plane gets its wings scorched off on reentry. I also used Intake build aid to balance the intakes. Your previous content has been restored. Hot ground causes air to rise, cooling as it moves away from the heat, which leads to increased density and a resulting fall back down. If your Mk3 design jam-packed full of heavy gear can't seem to survive reentry, one option might be to reduce the payload a bit. - Make sure you have enough control authority to lift the nose up. If you plan on either dropping off cargo or picking up cargo and traveling with it, you'll generally want to locate your cargo bay at the middle of your center of gravity. It's strongly recommended to keep your landing gears well-spaced from each other to ensure that the aircraft will be difficult to roll into a collision. Wing shapes do not appear to have a significant impact on drag or drag-to-lift ratio at this time, but swept wings are still an easy way to help ensure that your center of lift stays behind your center of mass. But also check to make sure that your wheels are placed symmetrically and your engines are aligned properly. I'm trying to do some of the surveying and taxi-ing missions because now that's all the games giving me but flying with a regular rockets just not working for me. Obviously jet engines are air-breathing, so you need to include air intakes in your spaceplane. Now for wings, the "Wing Connector Type B" is the largest you have so far; connect a set of those where the centre of mass is. Now imagine what happens like that. They all had landing gear placed at the front and at the back. I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft. I just thought my planes were too heavy or not enough control surfaces. The Mk1 fuselage parts only tolerate up to 2000K, while Mk2 fuselages tolerate up to 2500K, and Mk3 fuselages tolerate up to 2700K. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! Necessary for heavy/long spaceplane. . You should have something called an "Elevon 1"; this will be the moving part for your wings. FOX 56 News Video More Videos Managed to fix it with some different wings; idk what was going on with the other ones but I was just thr FAT aeroplane wings. Otherwise, you can either shift your wings till it's right (though this may crowd them near the back), or you can very slightly rotate the big wings so they're slightly higher near the front of the plane. Landing is hard. I thought after buying this I would have all the parts I need to build a small plane that can at least get off the ground, but I'm having trouble. Subscribe! I managed to successfully takeoff and land this aircraft at least 20 times in a roll now and I haven't even lost a single pilot flying this. I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. These have an ISP of 800 in a vacuum which is significantly better than all other rocket motors except the very weak IX-6315 ion rocket. This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. One idea I haven't noticed here yet: "wire up" the landing gear, with strut connectors. For myself, it always was the position of landing gear in terms of pitch. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. Remember how you want your center of lift/drag to be behind the center of gravity? 2022 Take-Two Interactive Software, Inc. http://forum.kerbalspaceprogram.com/threads/99660-0-25-Adjustable-Landing-Gear-v1-0-4%28doors-fixed%29-Nov-14. Pasted as rich text. Your previous content has been restored. For some reason, when the plane is trying to take off and pulling up, the plane begins to bounce on it's front wheels (the back wheel kicks up), which hinders the plane taking off. LV-N "Nerv" nuclear thermal rockets are commonly used on SSTOs for the rocket stage if Rapiers are not used. Your link has been automatically embedded. https://forum.kerbalspaceprogram.com/index.php?/topic/124380-wing-lift-amp-wing-lift-to-drag-ratio-charts/, https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Spaceplane_basics&oldid=100619. Increasing the number of intakes will not allow you to continue using your jet engines at higher altitudes. Is there a way to rectify this problem. 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. KSP Quick Guides: Takeoff Troubleshooting Stock v.22 - YouTube This page was last edited on 17 December 2021, at 13:14. I moved the back landing gear to right underneath the COM. As you would expect, spaceplanes need wings: they have various shapes and dimensions, and they differ basically in lift rating: you will want to have enough lift to keep your fuselage approximately prograde during your ascent to orbit. That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. Tips aplenty in this thread: http://kerbalspaceprogram.com/forum/showthread.php/13851-The-woes-of-building-a-space-plane?highlight=woes+spaceplane It taught me everything I know, except for the stuff I learned elsewhere. But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls. While it's true that jet engines don't work in space, they offer one large advantage over rocket engines while inside the atmosphere: fuel efficiency. This helped immensely and if you haven't been doing this already, do it. When you are near the end of the runway, quickly activate then detach them to get the nose pointing up. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. How to keep an airplane stable on the runway in Kerbal Space - Arqade This ensures that your aircraft will go up once it achieves a high enough speed, and also helps with placing ailerons. Or maybe launching it in a vertical, Space Shuttle-style config. Mechjeb Spaceplane Guidance : r/KerbalSpaceProgram - reddit This is either a collider or design issue, if the craft doesn't have enough lift initially to get off the ground it will bounce a bit before taking off. (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. I have done everything imaginable to try to remedy this problem. And, of course, try to take off and land as slow as possible. Do agree that the rear wheels either need to be brought closer or or the Nenter of mass needs to be move closer to the rear wheels. With a tail-dragger, the plane is already angled up just sitting on its wheels so once the speed is high enough, it should just float up by itself.
