As such, you may want to line all forward Mk1 radial nodes on your aircraft with shock cones, if possible. Your very own tutorial.). As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. Such as not producing lift, which is not what you want with a plane. Clear editor. 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. 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. 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. Any ideas? Tell ya what, I'm gonna try to recreate that thing in my sandbox and see what I get. Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. here are some images and a gif. Check out the following guide for some good info: http://forum.kerbalspaceprogram.com/threads/52080-Basic-Aircraft-Design-Explained-Simply-With-Pictures And at the extreme, producing down force, which I'm sure would cause more gear issues. But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls. You probably won't have much luck landing the fuselage intact if your Mk3 plane gets its wings scorched off on reentry. For this to happen, I'm assuming you're using rocket fuel tanks. It is usually placed back because it can be placed further back than it is possible in the front (if it is placed in the front, it can obstruct the view of the pilot, which is undesired) as well as making the plane unstable (by the same effect that you would get if the center of lift (horizontal lifting surfaces) were in front of the center of mass, but with vertical surfaces). 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. However it's huge size can make it tricky to take off from the runway without destroying the engine. This helped immensely and if you haven't been doing this already, do it. Thanks for all the help. Cookie Notice A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. 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! Note that the lift rating does not mean that the wings will automatically lift a spaceplane into the air when it's moving forward. I see absolutely no need to be traveling that fast down the runway. 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. Display as a link instead, I dont really need 200m/s for take off. I have also thought about a wider base. I'm making sure that I keep trying to get it up but it just wont go! 3. angle of the wheels. wings, unless they're very well braced). I made this aircraft based on real life commercial jet design. 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. 1. You want to start by attaching a Mk 0 Liquid Fuel Tank under the wings, making sure you're mirrored so it goes under both wings. Keep your nose pointed prograde as you descend through the atmosphere. All lift-rating means is that the wing section will resist motion perpendicular to its plane. 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. You want to get up to get the gear tucked away and reduce drag. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. . It helps to have a center of gravity which is close to your engines so that the landing gears can be close to both. At that point, the plane could potentially start spinning around as a result of losing the benefit of the gimbal control of the engine. 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). Press question mark to learn the rest of the keyboard shortcuts. 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 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. All trademarks are property of their respective owners in the US and other countries. (Source). EDIT: It was the b9 procedural wings. You could do it the kerbal way by attaching two SRBs to the nose of the plane pointing upwards. Brakes in the back keep you stable. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes. Consequently, atmospheric reentry is less dangerous with a Mk2 or Mk3 fuselage, compared to reentry with Mk1 fuselages. These should be in the bottom left next to the display of the cost of the aircraft. Pasted as rich text. For all your gaming related, space exploration needs. Does anybidy have any tips on how to build spaceplanes? KSP handling death investigation High Winds Cause Widespread Power Outages Ohio . Similar principles apply when finding suitable landing sites away from the KSC. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! Valve Corporation. If you're tired of big rockets that use tons of fuel and disintegrate in the atmosphere when coming back to Kerbin, this tutorial is perfect for you! 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. You can also angle the wings themselves slightly upwards (using WASDQE) in order to make them generate more lift when horizontal. 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). The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. KSC's runway is slightly north of Kerbin's equator and perfectly flat. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. That, combined with a Unity joint bug, makes your plane bounce. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. Those and the fixed main gear are NOTORIOUSLY bouncy. I don't have any mods but sometimes a problem may be a simple bug. The FedEx plane pulled back up in time to avoid a collision. Install S5 moon rocket By lightbreaker_64. Enable mirror symmetry to save yourself some alignment effort. Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. if its too far behind plane cannot lift. I have built lots of spaceplanes. - Make sure the landing gear is as close to the center of gravity as possible, just slightly behind it (for nosewheel aircraft). Upload or insert images from URL. Symmetry placement should give you perfect symmetry, as far as the game is concerned. 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? First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. 200 m/s runway stability just doesn't seem to have a worthwhile purpose to me, and is inducing counter productive engineering challenges. 2022 Take-Two Interactive Software, Inc. Note that no wings will tolerate more than 2400K, so the difference in temperature tolerance between Mk2 and Mk3 fuselages isn't terribly significant. More mass will mean it takes more drag to slow down on reentry, which will mean you go faster at lower altitudes and experience more reentry heating. Slowly pitch up to avoid overheating. If you have an account, sign in now to post with your account. After placing wheels I always use the rotate gizmo on snap with absolute orientation. They sometimes coincide with ailerons on some, more space-economical, aircraft. Firstly you're going to want to make a short fuselage. They all had landing gear placed at the front and at the back. Subscribe! Landing is hard. You can deploy your chutes just prior to touchdown for rapid deceleration. A control surface with 100% control surface portion will weigh twice as much as a wing with the same lift would weigh. Control surfaces are heavier than wings. Also note that for maximum efficiency, you should make sure that your horizontal control surfaces are rotated to exactly the same pitch that you've rotated your wings. * Unlock steering and disable brakes on front gear. And above all: have fun! 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. S5 moon rocket by lightbreaker_64. 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. LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. Necessary for heavy/long spaceplane. 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. Clear editor. 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. 1. tilt of the plane. For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch. Please consider starting a new thread rather than reviving this one. This page was last edited on 19 February 2020, at 07:08. Display as a link instead, 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. 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. Then this tutorial is for you. 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. I also used Intake build aid to balance the intakes. 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. Do you have a screenshot of the craft? You can post now and register later. But be careful and don't crash it! 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. They sometimes coincide with elevators. my planes keep flipping backwards on take off . Quick context, I am a software engineer. 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. I moved the back landing gear to right underneath the COM. This would indicate two problems. They could go up to 120 m/s on the runway and still not lift up. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. This is most likely the standard jitterbugging problem. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. KSP 2 speculation: I believe terraforming will be a feature of the game. Pasted as rich text. You cannot paste images directly. For more information, please see our Re-entry heating can destroy parts of your spaceplane, or destroy it entirely. Such flight involves lift-induced drag, but reduces the total thrust required to traverse a distance at a given speed. Please consider starting a new thread rather than reviving this one. If you forget to put an air intake on your airplane, don't worry! Try not to place your gears to wings, especially wingtips - if they wobble even slightly, your plane lose the balance. 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). my center of lift is always slightly infront of my mass. I was wrong. The plane is clearly unstable. This is just a general briefing section with lots of "to do" or "not to do" things: when you think you've got it, check the Aeris 4A tutorial mission to learn how to get into space easily. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. 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. 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. 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. You want an elevon on each set of wings. 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. The Kerbal Space Program subreddit. 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. The most dangerous part of a spaceplane flight is returning from orbit. When you are near the end of the runway, quickly activate then detach them to get the nose pointing up. The Mk1 fuselage parts only tolerate up to 2000K, while Mk2 fuselages tolerate up to 2500K, and Mk3 fuselages tolerate up to 2700K. I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. 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. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. . As with everything in KSP, experiment, experiment, experiment. 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? This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. First try speed over land reached over 210 m/s before flipping in the last second. Take the large delta wings and place them on the aircraft. At around . 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. For myself, it always was the position of landing gear in terms of pitch. As such, you will need various control surfaces. (Idea is moot, if you haven't unlocked them yet.) It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. Rapiers generally provide less thrust than a Whiplash at speeds below mach 2, but provide more thrust at higher speeds. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. Saves a lot of headache in wheels placement. 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. To slow down faster, you can increase the braking strength of your rear wheels. All I have are the parts from the Aerodynamics tech and the gear bay (wheels). In vanilla KSP, wings have a predefined lift factor. 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.
