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. This is for the same reason that you keep your fuel balanced. All of these problems can be exacerbated or reduced by adjusting the amount of fuel in your tanks during landing. Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. It is due to the spinning up of the engines. That said, parachutes are an exceedingly effective means of reducing your stopping distance. Aim to get your speed below 50m/s, and have plenty of water ahead of you; keep the plane level, and pitch up to shed velocity. here are some images and a gif. Sometimes taking things off and re-attaching them does it, or you may have to go so far as to scrap the design and rebuild. Congratulations! Necessary for heavy/long spaceplane. 1. make sure your main gear is not wobbling (ie. 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! KSP Stock Space Shuttle by _ForgeUser18393701. That, combined with a Unity joint bug, makes your plane bounce. They all had landing gear placed at the front and at the back. wings, unless they're very well braced). So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. They sometimes coincide with elevators. Does anybidy have any tips on how to build spaceplanes? When I use it for spaceplane guidance it keeps me on the correct heading, but the flight is very busy sine wave of a path. I checked my planes and I found the problem. If you can maintain level flight at about 30-40 m/s, you should be able to perform an ocean landing if needed. These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. 1. my center of lift is always slightly infront of my mass. This helps to keep the performance of your spaceplane stable with any amount of fuel. 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. as Shkeec said check gear check gear check gear. Angled landing gear create rotational force for whatever reason. 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. How to Fly a Plane - KSP Beginner's Tutorial - YouTube 0:00 / 25:53 How to Fly a Plane - KSP Beginner's Tutorial Mike Aben 30.6K subscribers 78K views 2 years ago KSP - Absolute Beginner's. I also used Intake build aid to balance the intakes. Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. I'm trying to do some of the surveying and taxi-ing missions because now that's all the games giving me but flying with a regular rockets just not working for me. 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. All trademarks are property of their respective owners in the US and other countries. Do you have new pics after you moved the rear wheels forward? Cure: Draw a mental axis from the nose to the tail of the plane and use the rotate tool (summetry on), on one of the wheels. This makes design easier, eliminating all concern for balancing jet fuel against rocket fuel. But be careful and don't crash it! Cookie Notice Slowly pitch up to avoid overheating. * Unlock steering and disable brakes on front gear. Here are a few pictures of it: Take a picture with center of mass and center of lift turned on. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. 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. 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 just built a plane but when i launch it just slides and spins slowly to the right, any ideas on why this is happening? Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. It Flips Up And Towards The Opposite Direction. Powered by Invision Community. 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. 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. While I am not a great plane builder there is a part in the structural (I think it is a pylon?) symmetry building makes them face slightly towards (or away from) each other, with wobbly results. I see absolutely no need to be traveling that fast down the runway. An altitude set to 18,000 meters tops off at 19,000 meters and drops to 15,700 meters . As with everything in KSP, experiment, experiment, experiment. However, they do take a conventional mix of fuel and oxidizer, and thus require much more fuel mass than jet engines or LV-N Nerv. Quick context, I am a software engineer. 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. The Kerbal Space Program subreddit. Having said all that, these are the issues you must contend with. Easier just to bring the rear wheels closer as well as a in line reacton wheel. I was wrong. 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). One final point to consider is the mass you're planning to store in the fuselage. 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? Nothing bad will happen. 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. Mk2 aircraft may be able to get away with it, but even then it's often best to space them further out. See the tutorial below. Be aware that landing on water is an option if your spaceplane can fly level at less than ~40-50 m/s. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Notice how the landing gears are placed out on the wings. 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. 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. A good example of this is at the KSC runway when landing on a 90 degree bearing. It helps to have a center of gravity which is close to your engines so that the landing gears can be close to both. How wide is the base. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . Paste as plain text instead, 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. If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. You can deploy your chutes just prior to touchdown for rapid deceleration. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. See if there is still a problem when only travelling slowly, say <20m/s. 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. Besides the good advice others have given, I would also be very careful with that little tailwheel. 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. Keep your nose pointed prograde as you descend through the atmosphere. 2022 Take-Two Interactive Software, Inc. 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. 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. Consequently, atmospheric reentry is less dangerous with a Mk2 or Mk3 fuselage, compared to reentry with Mk1 fuselages. Having landing gears near the front and back of your aircraft can also help to ensure that you won't break your engines or smash your cockpit into the runway. I wanted to develop a plane to check how are the aerodynamics physics working, and went back to the KSC VAB to design a little plane. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. 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. 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. Landing speed (minimum speed for level flight) can be reduced by adding components to increase maneuverability, by using larger wings, by increasing wing angle of attack on the fuselage (3-5 degrees is the recommended range for a spaceplane to achieve the best lift-to-drag ratio [source]), and by decreasing the weight of the aircraft. That's over 2x the normal recommended max. Your very own tutorial.). KSP handling death investigation High Winds Cause Widespread Power Outages Ohio . Do you have a screenshot of the craft? 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. Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. Yours is a very light plane, and the standard suspension settings are for a medium heavy plane -- so your suspension is too stiff. Your previous content has been restored. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. They sometimes coincide with ailerons on some, more space-economical, aircraft. When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. Either one of those being misaligned will cause instability on the runway during takeoff (and the engines misaligned will cause flight problems). You could do it the kerbal way by attaching two SRBs to the nose of the plane pointing upwards. 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. If there is, I would have found it long ago. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. 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 I have played the game for 200 hours and I love it. 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. 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. 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. 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. 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. Enable mirror symmetry to save yourself some alignment effort. Either put more engines or reduce the amount of rocket fuel. 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. if its too far behind plane cannot lift. I was wrong. 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. Then this tutorial is for you. For an example, see the A-10 Warthog's landing gears: link. 3. make sure your center of mass is slightly in front of center of lift force. For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch. 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. They all had to use the runway drop to take off. Your link has been automatically embedded. 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! Note: The large delta wing will ensure you won't backflip. Try disabling friction control with on the front landing gears. This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. They all had to use the runway drop to take off. I was attaining high speeds on the runway without getting off the ground, which made the plane yaw back and forth.
