Also, excessive use of the rudder usually causes the plane to spin out of control and crash. This material may not be published, broadcast, rewritten, or redistributed. Remember how you want your center of lift/drag to be behind the center of gravity? If you use an Advanced SAS, and raise your front landing wheel so that it is higher than the rear wheels, by just turning the SAS on and going full throttle, due to the 10 degree angle of the plane, it should eventually take off by itself. It is due to the spinning up of the engines. Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. Such as not producing lift, which is not what you want with a plane. Here is an example of landing gear place on a complex geometric surface: Unstable plane Rear landing gears only seems to work on cylindrical fuselage, if you place them on a fuselage intake or anything other than a cylinder, the wheels can behave strangely. So you want to make a plane but all your contraptions explode on the runway, crash into the runway a few seconds after taking off, crash into the side of the runway, crash into the ocean after doing a tight turn or otherwise fail to do what you intended? You can post now and register later. When your altitude reaches 35km, start pulling up gently. - SF. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. Thanks for the help guys. 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!). 5.whether the body you anchor the landing gears to are firm. 3. make sure your center of mass is slightly in front of center of lift force. 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. Mechjeb Spaceplane Guidance. I can not get any aircraft-style spaceplane take off from the runway, they will stay on until the end, where the engines crash into the ground and explode. Beyond that, you're going to get some wobble once you get close to take off speed. Do you have a screenshot of the craft? - KSP Matt Lowne 527K subscribers 1.3M views 2 years ago I've wanted. 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. Note that as you fly higher the air intakes will become less effective and you may come to a point when the engines will shut down due to the lack of air. * Gear not mounted to parts that will flex (e.g. All rights reserved. @TheEnvironmentalist There is one more method I'm sure would work in your case, although I didn't write about it because I think it's cheesy and wouldn't solve the root problem. i have no idea why this happens please help. The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. And at the extreme, producing down force, which I'm sure would cause more gear issues. Go on, and take the plane capsule which looks like a converted fuel storage device Contents 1 Making a fuselage 2 Understanding Lift 3 Control Surfaces 3.1 Elevator 3.2 Aileron 3.3 Rudder 4 Landing gear Making a fuselage Any plane needs speed - so you need thrust (usually). Doesnt make sense so just do this: Nope that didn't solve anything, even when the plane is past the runway and gliding on the little bit of space before the ocean it will slowly lower to the ocean, what am I doing wrong? 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. Unstable Aircraft: "FAR Firehound" (Stock). I also used Intake build aid to balance the intakes. That said, parachutes are an exceedingly effective means of reducing your stopping distance. Note: Your post will require moderator approval before it will be visible. 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? For an example, see the A-10 Warthog's landing gears: link. You can also angle the wings themselves slightly upwards (using WASDQE) in order to make them generate more lift when horizontal. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. That, combined with a Unity joint bug, makes your plane bounce. 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 Clear editor. FOX 56 News Video More Videos 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. Re-entry heating can destroy parts of your spaceplane, or destroy it entirely. It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. my center of lift is always slightly infront of my mass. That will align with the craft axis. While all other cargo bays are fine for making spaceplanes, the Mk3 Cargo Ramp produces obscene amounts of drag, which can easily prevent reaching orbital velocities by itself. I have created a score of other aircrafts with different designs but deleted them because they didnt work even on the runway. I was attaining high speeds on the runway without getting off the ground, which made the plane yaw back and forth. All the weight is pushed on the middle and it can't pull up. Hit the launch button and watch your magnificent bird fly! 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! 1. make sure your main gear is not wobbling (ie. DO NOT ANGLE THEM! Subscribe! Nothing bad will happen. So I have played the game for 200 hours and I love it. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. What you ought to be using is the Swept Wings and Elevon 1s instead of the Delta-Deluxe Winglets. Landing also often requires rapid deceleration to avoid running off the end of the runway or crashing into a slope when landing on open terrain. Firstly, inadequate air intakes for the number and type of engines you're using (causing some engines to shut down before others). 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. Having said all that, these are the issues you must contend with. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. They all had landing gear placed at the front and at the back. For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch.

All of them had one thing in common though. As such, you may want to line all forward Mk1 radial nodes on your aircraft with shock cones, if possible. 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. My plane usually take off at a little over 120m/s. I just thought my planes were too heavy or not enough control surfaces. Even a small deviation can cause serious instability, making your aircraft bounce and jolt left and right even during takeoff. Cookie Notice Enable mirror symmetry to save yourself some alignment effort. I have doubled the max stress value for aerodynamics failure in FAR for every category. The plane is clearly unstable. Depending on which surface you place them on, they might not be parallel to the axis in which case. (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. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. I started investigating why this was happening. Wow, if you need 200 m\s to take off, you should think about adding more lift. 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. 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. Mods needed for this aircraft to work: Procedural wings, Adjustable Landing Gear, FAR. This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. This allows you to takeoff at lower speeds and on shorter runways, and likewise for landing. * Unlock steering and disable brakes on front gear. KSP 2 speculation: I believe terraforming will be a feature of the game. Thank you and happy landings. First try speed over land reached over 210 m/s before flipping in the last second. Go on, and take the plane capsule which looks like a converted fuel storage device. Thanks for all the help. wings, unless they're very well braced). 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. Make sure that all of your landing gears are pointing in exactly the same direction. Here, the. Now imagine what happens like that. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. everytime i make a powered plane, it always flips over and points backwards after i take off. . Quick context, I am a software engineer. Such flight involves lift-induced drag, but reduces the total thrust required to traverse a distance at a given speed. 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.
