Rapiers generally provide less thrust than a Whiplash at speeds below mach 2, but provide more thrust at higher speeds. as Shkeec said check gear check gear check gear. You cannot paste images directly. Depending on which surface you place them on, they might not be parallel to the axis in which case. Also avoid the basic fin for the same reason. 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. Enable mirror symmetry to save yourself some alignment effort. Make sure that all of your landing gears are pointing in exactly the same direction. #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. Now imagine what happens like that. 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. 2022 Take-Two Interactive Software, Inc. 200 m/s runway stability just doesn't seem to have a worthwhile purpose to me, and is inducing counter productive engineering challenges. I moved the back landing gear to right underneath the COM. It is also common to add an Inline Clamp-O-Tron, which, unlike all the other docking ports, can be placed in the middle of the spacecraft (a handy solution, since there is not much space at either end of the craft) to allow your plane to dock with space stations or other spacecrafts. All trademarks are property of their respective owners in the US and other countries. 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. Conversely, if you keep all of the fuel in the back, you may find that your center of mass gradually drifts so far in front of your center of lift that you can't keep your nose up anymore, also potentially resulting in a fatal scenario. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). Hopefully this gets you your first aircraft that can take off and land, which is the biggest hurdle to being able to make KSP aircraft. Or maybe launching it in a vertical, Space Shuttle-style config. EDIT: So, I set the front landing gear spring and damper to 0.5, and also set the tail gear spring and damper to 2, and the problem was fixed! If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. Note: Your post will require moderator approval before it will be visible. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . I feel tat it is either due to the symmetry placement in this game being inaccurate or certain parts where i anchor my landing gears on are not perfectly symmetrical and the physics calculation is just too sensitive about even the slightest misalignment. Unfortunately, with only these basic parts, landing on the runway won't be easy; a viable alternative is to throttle down to nothing, then belly-flop in the ocean. 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 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 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. 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. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. 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 Stock Space Shuttle by _ForgeUser18393701. (Idea is moot, if you haven't unlocked them yet.) How do I fix this? Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Note: This tutorial was last updated for version 1.7.2. Be aware that landing on water is an option if your spaceplane can fly level at less than ~40-50 m/s. The centre of mass was between the 2 landing gears. . if mounted on not struted part) 2. put your main gear slightly behind center of mass. Your wheels should now have 0 degree angle between them, meaning they are both. 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. FOX 56 News Video More Videos 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. 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. 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!). Upload or insert images from URL. 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. If you're planning on landing on a somewhat uneven surface, like an open grassland somewhere on Kerbin or an island on Laythe, consider packing some parachutes for deceleration. Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. Mk2 aircraft may be able to get away with it, but even then it's often best to space them further out. This thread is archived . Easier just to bring the rear wheels closer as well as a in line reacton wheel. 1. make sure your main gear is not wobbling (ie. The reverse also happens. LV-N engines also have the advantage of using the same liquid for propellant that jet engines use for fuel. You can resolve the emergency by transferring fuel from rear fuel tanks to forward fuel tanks, but you should alter your design to bring your wings further back to prevent such incidents in the future. 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. I have built lots of spaceplanes. Try disabling friction control with on the front landing gears. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. and our Saves a lot of headache in wheels placement. Edit: I made a simple easy plane in career mode that is both stable and cheap: A trick i've used before is to put modular girders on the sides of the fuselage and putting the gear on the bottom of the girders. You can post now and register later. For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch. - SF. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. For all your gaming related, space exploration needs. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. It is also said that a good landing is one you can walk away from. And above all: have fun! A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. This is most likely the standard jitterbugging problem. Even with a stable landing, you may find that you don't have enough room on your desired landing area to come to a stop before you reach the end. 3. angle of the wheels. Mechjeb Spaceplane Guidance. Balanced fuel saves Kerbal lives. 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. 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. While having the same stock parts as in the VAB, spaceplane design is obviously quite different from pure rocket design. Powered by Invision Community. I don't have any mods but sometimes a problem may be a simple bug. 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. The plane is clearly unstable. 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. 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. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. If you keep all of the fuel in the front, you may find that your center of mass drifts backwards as your fuel drains. Here is your convenient solution to this problem! Descending greater than -10 m/s usually makes a mess. I am definitely aware that there are multiple reasons as to why the plane flips. Any ideas? Re-entry heating can destroy parts of your spaceplane, or destroy it entirely. 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. So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. http://www.youtube.com/user/Cruzanak?. 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. Press question mark to learn the rest of the keyboard shortcuts. The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. 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. Increasing the number of intakes will not allow you to continue using your jet engines at higher altitudes. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. For example, having your landing gears located near the ends of the wings is an easy way to ensure that you don't roll and shred your wings when landing or taking off. Wow, if you need 200 m\s to take off, you should think about adding more lift. Safety note: Disable the brakes on the front landing gear.
