ksp plane takeoff

So if I start encountering wobble it's time to pull back on the stick and get in the air. Paste as plain text instead, I see absolutely no need to be traveling that fast down the runway. Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. Any ideas? Depending on which surface you place them on, they might not be parallel to the axis in which case. Center of Mass and Center of Lift are the usual causes of instability. Or adding a RATO boosters. While it's true that jet engines don't work in space, they offer one large advantage over rocket engines while inside the atmosphere: fuel efficiency. Landing can be trickier for spaceplanes since they are designed for higher speeds than other aircraft and may not be able to fly level at speeds low enough for an easy landing (<50 m/s). You're going to have a bad time. FOX 56 News Video More Videos (For test purposes, all aircraft are not pitched up and SAS is turned off. Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. Congratulations! After placing wheels I always use the rotate gizmo on snap with absolute orientation. Hot ground causes air to rise, cooling as it moves away from the heat, which leads to increased density and a resulting fall back down. All trademarks are property of their respective owners in the US and other countries. Quick context, I am a software engineer. 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 FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. Thanks for the help guys. Secondly, it would suggest that your spaceplane's center of lift is too far forward compared to its center of gravity (causing the uncontrollable spin). Consequently, atmospheric reentry is less dangerous with a Mk2 or Mk3 fuselage, compared to reentry with Mk1 fuselages. Works well on small craft. It Flips Up And Towards The Opposite Direction. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. 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. 1. 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 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. * Gear not mounted to parts that will flex (e.g. Place your rear wheels/gear in front of the flaps on your wings. Is there a way to rectify this problem. 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. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). So I have played the game for 200 hours and I love it. 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), which hinders the plane taking off. 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? 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. 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. 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? You can post now and register later. 1. make sure your main gear is not wobbling (ie. If you can give a craft file and a mod list I could take a look. 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). Just like with rockets, get some courageous Kerbal in the cockpit and let's get started! If your spaceplane is difficult to land when full of fuel but easy to land when empty, then it may be helpful to burn off or transfer out most of the excess fuel before landing to make the aircraft lighter. 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? Try disabling friction control with on the front landing gears. Clear editor. When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. 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 If your Mk3 design jam-packed full of heavy gear can't seem to survive reentry, one option might be to reduce the payload a bit. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. All lift-rating means is that the wing section will resist motion perpendicular to its plane. If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. This thread is archived . When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. 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. 2022 Take-Two Interactive Software, Inc. http://kerbalspaceprogram.com/forum/showthread.php/13851-The-woes-of-building-a-space-plane?highlight=woes+spaceplane. Here is your convenient solution to this problem! If you forget to put an air intake on your airplane, don't worry! This thread is quite old. Symmetry placement should give you perfect symmetry, as far as the game is concerned. 2022 Take-Two Interactive Software, Inc. http://forum.kerbalspaceprogram.com/threads/99660-0-25-Adjustable-Landing-Gear-v1-0-4%28doors-fixed%29-Nov-14. 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. 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. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. 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! Your wheels should now have 0 degree angle between them, meaning they are both. They all had landing gear placed at the front and at the back. KSP 2 speculation: I believe terraforming will be a feature of the game. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. 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. 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. 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. - Make sure the landing gear is as close to the center of gravity as possible, just slightly behind it (for nosewheel aircraft). 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. 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. Brakes in the back keep you stable. I was attaining high speeds on the runway without getting off the ground, which made the plane yaw back and forth. Increasing the number of intakes will not allow you to continue using your jet engines at higher altitudes. 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. symmetry building makes them face slightly towards (or away from) each other, with wobbly results. The most dangerous part of a spaceplane flight is returning from orbit. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. I just thought my planes were too heavy or not enough control surfaces. This can easily cause you to crash on landing. Descending greater than -10 m/s usually makes a mess. 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. At around . 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). Alternatively, you can try landing at higher speeds with your nose pointed further down, but this increases challenges with stability and deceleration while on the runway. While I am not a great plane builder there is a part in the structural (I think it is a pylon?) 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. Be aware that while this angle will provide the lowest possible landing speed for your spaceplane, it will create problems if your center of gravity is too far ahead of your rear landing gears (causing a high-speed nose collision on touchdown) or if your rear landing gears are too far ahead of your engines, causing them to strike the runway first. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. Note: Your post will require moderator approval before it will be visible. Privacy Policy. Some testing is usually required with new designs to determine the best ascent profile. You should have something called an "Elevon 1"; this will be the moving part for your wings. 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. (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. It's said that takeoffs are optional but landings are mandatory. 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. I have created planes that have landing gears place right under the wing tips but they still won't work. Next you need landing gear. 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). If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. Note that no wings will tolerate more than 2400K, so the difference in temperature tolerance between Mk2 and Mk3 fuselages isn't terribly significant. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. if mounted on not struted part) 2. put your main gear slightly behind center of mass. 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. 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. I don't have any mods but sometimes a problem may be a simple bug. Obviously jet engines are air-breathing, so you need to include air intakes in your spaceplane. 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? Firstly, inadequate air intakes for the number and type of engines you're using (causing some engines to shut down before others). You want an elevon on each set of wings. When your altitude reaches 35km, start pulling up gently. . 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. 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. 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. Wow, if you need 200 m\s to take off, you should think about adding more lift. Or maybe launching it in a vertical, Space Shuttle-style config. They all had to use the runway drop to take off. Everything looks perfectly symmetrical as far as I can tell. Remember how you want your center of lift/drag to be behind the center of gravity? For all your gaming related, space exploration needs. So the answer is: in the SPH, click on your front gear, set the spring to .5 and set the damper to .5 -- then save it and give it another shot at launching. Real planes do this as well. I have doubled the max stress value for aerodynamics failure in FAR for every category. (Yes, you personally, you lucky thing! Press question mark to learn the rest of the keyboard shortcuts. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. 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. I have done everything imaginable to try to remedy this problem. And above all: have fun! Thermal turbulence, caused by convection, happens below clouds and typically only impacts planes during takeoff and landing. 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. The issue is my plane rolls very sharply to the left any time I pitch up. Balanced fuel saves Kerbal lives. 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. 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! I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft. Now put on center of mass and center of lift view, and move the delta wings until the center of lift is slightly behind of the center of mass - not in front, otherwise your aircraft will be able to easily flip out of control. I have built lots of spaceplanes. Bit late i know, but i had the same problem. Besides the good advice others have given, I would also be very careful with that little tailwheel. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. For more information, please see our All of these problems can be exacerbated or reduced by adjusting the amount of fuel in your tanks during landing. 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.
