To maximize lift, your aircraft should rest on the ground with the fuselage tilted upward at anywhere up to a 25-27 angle so that the wings will end up tilted back at up to 30. It's said that takeoffs are optional but landings are mandatory. Beyond that, you're going to get some wobble once you get close to take off speed. So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. 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. Everything looks perfectly symmetrical as far as I can tell. I was wrong. However it's huge size can make it tricky to take off from the runway without destroying the engine. How do I fix this? 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. Any plane needs speed - so you need thrust (usually). When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. Pasted as rich text. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. I took off and at 60 m/s I was in the air! As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. Although I usually only need 50 m/s for most planes to wobble out of control. http://kerbalspaceprogram.com, Press J to jump to the feed. Congratulations! 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 forget to put an air intake on your airplane, don't worry! Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. if its too far behind plane cannot lift. (Idea is moot, if you haven't unlocked them yet.) To takeoff and land at low speed, it's helpful to rotate the wings so the leading edge is slightly above the trailing edge. Note: The large delta wing will ensure you won't backflip. everytime i make a powered plane, it always flips over and points backwards after i take off. You can post now and register later. 2022 Take-Two Interactive Software, Inc. It is also said that a good landing is one you can walk away from. Hit the launch button and watch your magnificent bird fly! 1. tilt of the plane. Now for wings, the "Wing Connector Type B" is the largest you have so far; connect a set of those where the centre of mass is. The default max stress value is just ridiculous, its like flying in hair gel, everything gets torn apart so easily, like that will ever happen in real life. Now imagine what happens like that. To minimize drag, vertical tail fins can be kept minimal, since aircraft can be maneuvered adequately by roll and pitch alone. All lift-rating means is that the wing section will resist motion perpendicular to its plane. So if I start encountering wobble it's time to pull back on the stick and get in the air. Another trick is to move the rear landing gear forward, closer to the center of gravity. Why is it doing this? - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! 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). 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. If there is, I would have found it long ago. I feel tat it is either due to the symmetry placement in this game being inaccurate or certain parts where i anchor my landing gears on are not perfectly symmetrical and the physics calculation is just too sensitive about even the slightest misalignment. Paste as plain text instead, 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. To avoid swerving on takeoff and landing, it is strongly recommended to turn off or reduce the strength of the front brake on your aircraft, as well as to reduce the friction control. 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. Alternatively, if you're returning from a high orbit or from an interplanetary trip, you can try repeated shallow passes through the atmosphere. DO NOT ANGLE THEM! KSP Stock Space Shuttle by _ForgeUser18393701. Elevators are usually places in the front or back of an aircraft, and their function, as the name implies, is to change the pitch of the nose up and down. 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. Now right click each elevon and the tail fin and set what movement each controls; the ones on the large wings control roll only, the ones on the back wings control pitch only, and the tail fin controls yaw only. That will align with the craft axis. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. The reverse also happens. 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. 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. I have found a solution to my problem. KSC's runway is slightly north of Kerbin's equator and perfectly flat. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Also avoid the basic fin for the same reason. That's over 2x the normal recommended max. 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). It helps to have a center of gravity which is close to your engines so that the landing gears can be close to both. This is for the same reason that you keep your fuel balanced. 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. 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. Wow, if you need 200 m\s to take off, you should think about adding more lift. This thread is quite old. 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. 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. Note that no wings will tolerate more than 2400K, so the difference in temperature tolerance between Mk2 and Mk3 fuselages isn't terribly significant. - Make sure the landing gear is as close to the center of gravity as possible, just slightly behind it (for nosewheel aircraft). For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch. * Gear not mounted to parts that will flex (e.g. here are some images and a gif. This is starting to get really frustrating. Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Any ideas? For spaceplanes, avoid the FAT parts (wing, tail fin, and control surface). See the tutorial below. 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. You can even try refueling it before recovering your spaceplane further increasing your recovering value. 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. 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. 1. 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. Rapiers generally provide less thrust than a Whiplash at speeds below mach 2, but provide more thrust at higher speeds. 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. 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. Please consider starting a new thread rather than reviving this one. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. 67K subscribers in the KerbalAcademy community. Powered by Invision Community. 1. make sure your main gear is not wobbling (ie. For an example, see the A-10 Warthog's landing gears: link. 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. They could go up to 120 m/s on the runway and still not lift up. Your previous content has been restored. I worked through the tutorials and I think my problem was most often a lack of lift, or perhaps more accurately sufficient control surfaces. The issue is my plane rolls very sharply to the left any time I pitch up. 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 want an elevon on each set of wings. 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. This page was last edited on 14 April 2021, at 01:04. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! When your nose is stable at about 10 degrees above the horizon, pull up hard and keep it pulled. After a successful touchdown, high-speed motion on the runway (let alone uneven ground) can be unstable, causing the aircraft to careen to one side or the other, potentially resulting in loss of a wing and sometimes the entire aircraft. 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). 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? You cannot paste images directly. For a Mk1-based aircraft, your rear landing gears should not be tightly tucked together on the fuselage. To slow down faster, you can increase the braking strength of your rear wheels. But, likely guess is your craft is not producing enough lift. The FedEx plane pulled back up in time to avoid a collision. And at the extreme, producing down force, which I'm sure would cause more gear issues. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. 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. For myself, it always was the position of landing gear in terms of pitch. 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. All of these problems can be exacerbated or reduced by adjusting the amount of fuel in your tanks during landing. However, it's not a matter of "atmosphere or not", just a matter of air pressure which decreases rapidly with altitude. When gear is placed, it has just one point of attachment. 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. 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. Be aware that landing on water is an option if your spaceplane can fly level at less than ~40-50 m/s. 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. Keep in mind that lift rating and control surfaces are not connected: lift rating is basically the capacity of your wings to sustain the weight of your spaceplane, while control surfaces are parts of wing that can be moved to change the flow of the air around the plane and through this change a plane's direction, angle of attack or inclination. LV-N has less than 25% of its full power at Kerbin sea level. All trademarks are property of their respective owners in the US and other countries. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. 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? Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. 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). This can easily cause you to crash on landing. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 . 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. 2022 Take-Two Interactive Software, Inc. And above all: have fun! Real planes do this as well. Thanks for the help guys. Take the large delta wings and place them on the aircraft. If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. 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. 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). Some testing is usually required with new designs to determine the best ascent profile. The problem could be due to several issues. And also place them further apart. 1. make sure your main gear is not wobbling (ie. Thanks for everyone trying to help! When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. 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 This can turn into a fatal scenario if the center of mass gets behind the center of lift and you enter a flat spin. 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. 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. Obviously jet engines are air-breathing, so you need to include air intakes in your spaceplane. Note: This tutorial was last updated for version 1.7.2. 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 see absolutely no need to be traveling that fast down the runway. 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.
