You want to get up to get the gear tucked away and reduce drag. * Unlock steering and disable brakes on front gear. . 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. The issue is my plane rolls very sharply to the left any time I pitch up. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. All rights reserved. They are able to operate at higher altitudes and can even continue operating in a vacuum by switching to a rocket mode. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. Whether you're storing your fuel in fuselage sections, wing sections, or attached inside of cargo bays, it's generally a good idea to keep equal amounts of fuel at equal distances from your center of mass. Descending greater than -10 m/s usually makes a mess. One final point to consider is the mass you're planning to store in the fuselage. T-1 "Dart" engines are unique amongst conventionally-fuelled rocket engines: They have close to the highest efficiency in both vacuum and low atmosphere. It provides a wider, more stable wheel base while keeping the wheels straight up and down (no camber). Your very own tutorial.). In contrast, if you attempt a landing at the KSC runway on a 270 degree bearing, you run the risk of colliding with the upward slope shortly beyond the runway if you can't slow down initially and then can't speed up fast enough. 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. Here is the best aircraft I have created to date: Jet Aircraft. This plane will be able to take off, travel somewhere, perform a crew report, and then land. LV-N "Nerv" nuclear thermal rockets are commonly used on SSTOs for the rocket stage if Rapiers are not used. Though, I use the FAR mod which will change things, so I can't guarantee the results will be useful, but it might be interesting. The issue is my plane rolls very sharply to the left any time I pitch up. One idea I haven't noticed here yet: "wire up" the landing gear, with strut connectors. The tutorial below explains everything very well. Then at the top, we'll put one tail fin, centred on the end of the fuselage. When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. Flying a Space Station through a GAS GIANT! Throttle up to full, activate SAS, stage to start the engine (you'll only have one stage here), and start rolling (or sliding) down the runway! To maximize lift, your aircraft should rest on the ground with the fuselage tilted upward at anywhere up to a 25-27 angle so that the wings will end up tilted back at up to 30. Vice versa a plane with lots of control surfaces will be perfectly controllable (maybe even too much) but may have big difficulties with taking off and landing at reasonable speeds. Plane wobble during takeoff - Kerbal Space Program Forums Landing can be trickier for spaceplanes since they are designed for higher speeds than other aircraft and may not be able to fly level at speeds low enough for an easy landing (<50 m/s). To survive re-entry, it's recommended to start your approach back into the atmosphere at a shallow angle, ideally with a periapsis of around 30-35 km. S5 moon rocket by lightbreaker_64. An aircraft without control surfaces is like a rocket without RCS or reaction wheels - it will hardly turn and will be equally hard to control (perhaps even impossible!). Display as a link instead, 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! Spaceplanes generally ascend best on a 10-30 degree incline, often leveling out towards higher altitudes to pick up the maximum horizontal velocity before switching to rocket motors. Note: This tutorial was last updated for version 1.7.2. After externsive testing and bloodpressure rise, results: it doesnt matter where you place the wheels, as long as they are not angled on the X (nose-tail) axis. But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls. You can slow down either by deploying landing gears (and airbrakes if you have them) or by repeatedly pitching up and then back down to increase your drag. You cannot paste images directly. For a Mk1-based aircraft, your rear landing gears should not be tightly tucked together on the fuselage. Landing is hard. At that point, the plane could potentially start spinning around as a result of losing the benefit of the gimbal control of the engine. 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. When landing, you can achieve the highest lift for a given speed by raising the total angle of attack of your wings to 30 degrees (although this induces a great deal of drag). When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. Check out the following guide for some good info: http://forum.kerbalspaceprogram.com/threads/52080-Basic-Aircraft-Design-Explained-Simply-With-Pictures 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. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa Firstly you're going to want to make a short fuselage. - KSP Matt Lowne 527K subscribers 1.3M views 2 years ago I've wanted. 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. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 . This thread is quite old. Either put more engines or reduce the amount of rocket fuel. (Source). In vanilla KSP, wings have a predefined lift factor. However, I want to place my wheels where i want to and not only on X parallel surfaces. To takeoff and land at low speed, it's helpful to rotate the wings so the leading edge is slightly above the trailing edge. I believe the issue is there is not enough control surfaces to offset this issue, but it comes up very easy so it is not a very big deal. 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. Your previous content has been restored. For myself, it always was the position of landing gear in terms of pitch. To survive re-entry, it's recommended to start your approach back into the atmosphere at a shallow angle, ideally with a periapsis of around 30-35 km. 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. if its too far behind plane cannot lift. After a successful touchdown, high-speed motion on the runway (let alone uneven ground) can be unstable, causing the aircraft to careen to one side or the other, potentially resulting in loss of a wing and sometimes the entire aircraft. 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. Saves a lot of headache in wheels placement. Plane rolls uncontrollably on take-off : r/KerbalSpaceProgram This allows you to takeoff at lower speeds and on shorter runways, and likewise for landing. At around . An altitude set to 18,000 meters tops off at 19,000 meters and drops to 15,700 meters . Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. The only drawback to the reduced friction is reduced steering control, so this setting may need to be adjusted when taxiing to/from a runway, but should otherwise be kept minimal for takeoff and landing. You've just unlocked "Aviation" tech, you have a bunch of contracts that require you to stay at low altitude, and you want to build your first plane? That will align with the craft axis. 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. KSP Quick Guides: Takeoff Troubleshooting Stock v.22 - YouTube The design I used is similar to what I normally used for planes but I had to swap out parts and make it smaller to compensate for Career mode changes.

Note that the lift rating does not mean that the wings will automatically lift a spaceplane into the air when it's moving forward. Make sure that all of your landing gears are pointing in exactly the same direction. What you ought to be using is the Swept Wings and Elevon 1s instead of the Delta-Deluxe Winglets. (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 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. 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. 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. and our 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. An active front brake can cause your aircraft to rapidly and uncontrollably pivot left or right during landing, and high friction from the front wheel can potentially cause your plane to swerve violently both in landing and takeoff. But, likely guess is your craft is not producing enough lift. symmetry building makes them face slightly towards (or away from) each other, with wobbly results. First thing you're going to want to do in the SPH is turn on your centre of mass indicator (this is the point that the plane will rotate around when rolling, pitching, or yawing) and your centre of lift indicator (the Aerodynamic Overlay). All the weight is pushed on the middle and it can't pull up. 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. This allows you to avoid the extra weight and mass of additional fuselage parts, so you only have to deal with the extra weight of the fuel itself. Keep in mind that as your altitude increases, your control surfaces and winglets will become increasingly ineffective and will no longer work at all once you leave the atmosphere, so you may need to add alternative control systems like reaction wheels or RCS thrusters. 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. Mechjeb Spaceplane Guidance. Alright, it's late where I live so I'm gonna hit the hay and come back to it tommorrow, I read on the guide someone sent me and I think it is taht it doesn't have any way of pointing the up, so I'll tinker with some of the wings and see what I can do. Kerbal Space Program 2's early access launch is only for seasoned i have no idea why this happens please help. Tutorial: Your First Plane - Kerbal Space Program Wiki If, instead, all goes well, then once your jet engines have shut down you will need to start the second part of your space mission by switching to rockets. Temperature tolerance is the primary consideration for fuselage choice. They sometimes coincide with ailerons on some, more space-economical, aircraft. I also used Intake build aid to balance the intakes. For this to happen, I'm assuming you're using rocket fuel tanks. If you can maintain level flight at about 30-40 m/s, you should be able to perform an ocean landing if needed. They could go up to 120 m/s on the runway and still not lift up. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. To slow down faster, you can increase the braking strength of your rear wheels. Install S5 moon rocket By lightbreaker_64. 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. The problem could be due to several issues. Please consider starting a new thread rather than reviving this one. Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. Try getting the wings to deflect the air down, either by lifting the front end up using canards or by mounting them at an angle using shift + wasdqe. Such as not producing lift, which is not what you want with a plane. However, make sure to use struts when placing landing gears on the far edges of a multi-part wing because they may sag enough to cause a fuselage collision with the runway during landing. This is most likely the standard jitterbugging problem. As with everything in KSP, experiment, experiment, experiment. The default max stress value is just ridiculous, its like flying in hair gel, everything gets torn apart so easily, like that will ever happen in real life. How to keep an airplane stable on the runway in Kerbal Space - Arqade When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. 200 m/s runway stability just doesn't seem to have a worthwhile purpose to me, and is inducing counter productive engineering challenges. Keep your spaceplane pointed about 90 degrees above prograde so that the wings and body of your aircraft slow you down as much as possible. I was wrong. If you keep all of the fuel in the front, you may find that your center of mass drifts backwards as your fuel drains. Mk2 aircraft may be able to get away with it, but even then it's often best to space them further out. One FL-T100 tank can't power any rocket into space, yet a Shock Cone Intake, a Mk1 Inline Cockpit, a half-filled FL-T100 and a J-X4 "Whiplash" Turbo Ramjet Engine aimed in the general direction of "up" will let you laugh your way past the 70km mark at nearly 1200m/s. 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. 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. Drive gently off the runway and use the huge grassy field to take off, without care in the world about the plane veering to a side. 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! Cookie Notice Do you have new pics after you moved the rear wheels forward? Center of Mass and Center of Lift are the usual causes of instability. 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). Mods needed for this aircraft to work: Procedural wings, Adjustable Landing Gear, FAR. KSP handling death investigation High Winds Cause Widespread Power Outages Ohio . How to Fly a Plane - KSP Beginner's Tutorial - YouTube How do I fix this? They all had to use the runway drop to take off. I'm making sure that I keep trying to get it up but it just wont go! Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. First try speed over land reached over 210 m/s before flipping in the last second. I have also thought about a wider base. - Make sure you have enough control authority to lift the nose up. But also check to make sure that your wheels are placed symmetrically and your engines are aligned properly. After that, you face the challenge of touching down on the ground and coming to a stop safely without rolling and breaking off a wing or taking a nosedive and blowing your aircraft up on touchdown, or rolling off of the runway and into the ocean. 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), whichhinders the plane taking off. The Whiplash's ridiculous fuel efficiency allows a spaceplane to climb high into the atmosphere and gain a lot of speed while barely using any fuel at all. 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. Ideally, the wings should be tilted upward at an angle about 3-5 from the fuselage for optimal lift-to-drag ratio.[1]. It helps to have a center of gravity which is close to your engines so that the landing gears can be close to both. 2022 Take-Two Interactive Software, Inc. Is there a way to place landing gear so that i can guarantee my plane can remain stable on the runway even at high speed in excess of 200m/s? As such, you may want to line all forward Mk1 radial nodes on your aircraft with shock cones, if possible. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. The plane is clearly unstable. They sometimes coincide with elevators. These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. Valve Corporation. 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. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. Control surfaces are heavier than wings. Now imagine what happens like that. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). It Flips Up And Towards The Opposite Direction. This ensures that your aircraft will go up once it achieves a high enough speed, and also helps with placing ailerons. Or adding a RATO boosters. So if I start encountering wobble it's time to pull back on the stick and get in the air. It can be helpful to use a slightly taller front landing gear and slightly shorter rear landing gears so that your fuselage points slightly upward on the ground, thereby increasing the angle of attack of your wings while on the ground. Besides the good advice others have given, I would also be very careful with that little tailwheel. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. Your plane is almost finished. That said, parachutes are an exceedingly effective means of reducing your stopping distance. Now right click each elevon and the tail fin and set what movement each controls; the ones on the large wings control roll only, the ones on the back wings control pitch only, and the tail fin controls yaw only. Subscribe! I have created a score of other aircrafts with different designs but deleted them because they didnt work even on the runway. my planes keep flipping backwards on take off . Plane wobble during takeoff - KSP1 Gameplay Questions and Tutorials - Kerbal Space Program Forums Is there a way to place landing gear so that i can guarantee my plane can remain stable on the runway even at high speed in excess of 200m/s? - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! 67K subscribers in the KerbalAcademy community. Plane bouncing on takeoff - Gameplay Questions and Tutorials - Kerbal Space Program Forums Hello, I am having a small problem with a plane I have built. 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. Aircraft in this game is almost unfeasible, especially in career mode, you will lose all your money before you finally design an aircraft that can even takeoff. This can easily cause you to crash on landing. I don't have any mods but sometimes a problem may be a simple bug. The Kerbal Space Program subreddit. Easier just to bring the rear wheels closer as well as a in line reacton wheel. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. Tell ya what, I'm gonna try to recreate that thing in my sandbox and see what I get. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes.
