Just like with rockets, get some courageous Kerbal in the cockpit and let's get started! However, don't bother going overboard with intakes because your engines will still shut off at high altitudes due to the low air pressure regardless of how many intakes you have. The issue is my plane rolls very sharply to the left any time I pitch up. At around . However, I want to place my wheels where i want to and not only on X parallel surfaces. 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. These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. I had this one plane, very fast, It would go to 170 m/s on the runway then drop of the end and soar very nicely. 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? Control surfaces are heavier than wings. 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! Flying a Space Station through a GAS GIANT! 1. make sure your main gear is not wobbling (ie. All lift-rating means is that the wing section will resist motion perpendicular to its plane. my planes keep flipping backwards on take off . 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. How wide is the base. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. But, likely guess is your craft is not producing enough lift. This plane will be able to take off, travel somewhere, perform a crew report, and then land. I scoured the entire web for a solution, but found no working solution or at least dont work every time. The most dangerous part of a spaceplane flight is returning from orbit. Now imagine what happens like that. 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. If you pull up and cause the tailwheel etiher to hit the ground if it was already up or push it into the ground if it was still in contact, you will create bounciness. Not sure why you would want that stability for speeds in excess of 200 m/s though, as most planes will take off and land at far slower speeds. S5 moon rocket by lightbreaker_64. (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. This would indicate two problems. This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. Mechjeb Spaceplane Guidance. 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. 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. 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. Is there a way to rectify this problem. It is advised to place your control surfaces as far from your center of mass as possible. As such, you will need various control surfaces. Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. If you need to carry more fuel, consider using the Big-S Delta Wing as it provides the same lift-to-drag and lift-to-weight ratio as any other wing of the same mass, yet has the ability to carry fuel as well. Clear editor. Bit late i know, but i had the same problem. 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. 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). This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. Having said all that, these are the issues you must contend with. They sometimes coincide with elevators. Real planes do this as well. everytime i make a powered plane, it always flips over and points backwards after i take off. Either one of those being misaligned will cause instability on the runway during takeoff (and the engines misaligned will cause flight problems). Thanks for everyone trying to help! Wow, if you need 200 m\s to take off, you should think about adding more lift. 5.whether the body you anchor the landing gears to are firm. They sometimes coincide with ailerons on some, more space-economical, aircraft. 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! These should be in the bottom left next to the display of the cost of the aircraft. Pasted as rich text. 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. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 . 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. 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. Be aware that landing on water is an option if your spaceplane can fly level at less than ~40-50 m/s. If your rear wheels are too far back the aircraft will not be able to pivot on the wheels and lift its nose up. Heavy transport seaplane inspired to the Soviet Beriev A-40 Albatros which also appears in Evangelion 2.0! Rapiers generally provide less thrust than a Whiplash at speeds below mach 2, but provide more thrust at higher speeds. They could go up to 120 m/s on the runway and still not lift up. My Space Plane Keeps Flipping Backwards On The Runway. Saves a lot of headache in wheels placement. Also avoid the basic fin for the same reason. 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 . Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. 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. 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). If you have an account, sign in now to post with your account. It helps to have a center of gravity which is close to your engines so that the landing gears can be close to both. T-1 "Dart" engines are unique amongst conventionally-fuelled rocket engines: They have close to the highest efficiency in both vacuum and low atmosphere. Powered by Invision Community. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. This thread is quite old. The centre of mass was between the 2 landing gears. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. 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. 1. 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. 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. I'm making sure that I keep trying to get it up but it just wont go! Check out the following guide for some good info: Your wheel base is the problem. Here's a quick installment in to the. Hit the launch button and watch your magnificent bird fly! Brakes in the back keep you stable. For this to happen, I'm assuming you're using rocket fuel tanks. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. 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. Re-entry heating can destroy parts of your spaceplane, or destroy it entirely. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. i have no idea why this happens please help. While I am not a great plane builder there is a part in the structural (I think it is a pylon?) LV-N has less than 25% of its full power at Kerbin sea level. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. 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. The issue is my plane rolls very sharply to the left any time I pitch up. Beyond that, you're going to get some wobble once you get close to take off speed. 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. - SF. But be careful and don't crash it! I was wrong.

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. To slow down faster, you can increase the braking strength of your rear wheels. . 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. 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. It provides a wider, more stable wheel base while keeping the wheels straight up and down (no camber). - Have enough lift, either by a big wing area or high speed. Also, try this mod: http://forum.kerbalspaceprogram.com/threads/99660-0-25-Adjustable-Landing-Gear-v1-0-4%28doors-fixed%29-Nov-14 (still works in 0.90 if you get updated firespitter.dll). How do I fix this? Place your rear wheels/gear in front of the flaps on your wings. When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. (Source). Similar principles apply when finding suitable landing sites away from the KSC. 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 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. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. Your plane is almost finished. 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. Note: This tutorial was last updated for version 1.7.2. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! 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). Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. One idea I haven't noticed here yet: "wire up" the landing gear, with strut connectors. The problem could be due to several issues. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. I was wrong. This can easily cause you to crash on landing. Some testing is usually required with new designs to determine the best ascent profile. Enable mirror symmetry to save yourself some alignment effort. 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. 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. I also used Intake build aid to balance the intakes. Try disabling friction control with on the front landing gears. 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. This allows you to takeoff at lower speeds and on shorter runways, and likewise for landing. Valve Corporation. 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. Upload or insert images from URL. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa It is due to the spinning up of the engines. Such flight involves lift-induced drag, but reduces the total thrust required to traverse a distance at a given speed. if mounted on not struted part) 2. put your main gear slightly behind center of mass. The SSTO I took to Laythe recently has only one minor flaw using this design, I have to raise the landing gear and pull back slightly to take off. When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. (Idea is moot, if you haven't unlocked them yet.) 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. FAR says it would take an Angle of Attack of 24.3 degrees at 119 m/s to generate enough lift to get it to take off. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. 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. Let it get good and clear of the ground before applying any control to it. And at the extreme, producing down force, which I'm sure would cause more gear issues. You're going to have a bad time. 4. One final point to consider is the mass you're planning to store in the fuselage. 3. angle of the wheels. Does anybidy have any tips on how to build spaceplanes? Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. 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. That's over 2x the normal recommended max. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. 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). FOX 56 News Video More Videos 6.4K Downloads Updated Jun 7, 2017 Created Jun 7, 2017. . 67K subscribers in the KerbalAcademy community. If you can maintain level flight at about 30-40 m/s, you should be able to perform an ocean landing if needed. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. 1. make sure your main gear is not wobbling (ie. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. 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. 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. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes. LV-N "Nerv" nuclear thermal rockets are commonly used on SSTOs for the rocket stage if Rapiers are not used. Valve Corporation. Balanced fuel saves Kerbal lives. I just thought my planes were too heavy or not enough control surfaces. 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. 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. I worked through the tutorials and I think my problem was most often a lack of lift, or perhaps more accurately sufficient control surfaces. 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. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. Powered by Invision Community. 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. Consider placing your rear landing gears close to the spaceplane's center of mass, but be careful to avoid an engine collision with the runway. I have created a score of other aircrafts with different designs but deleted them because they didnt work even on the runway. Besides the good advice others have given, I would also be very careful with that little tailwheel. 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. 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. You cannot paste images directly. This plane will be able to take off, travel somewhere, perform a crew report, and then land.
