ksp plane takeoff

At that point, the plane could potentially start spinning around as a result of losing the benefit of the gimbal control of the engine. 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. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. This helps to keep the performance of your spaceplane stable with any amount of fuel. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! If that's not an option, you can still recover some value by landing at any suitable flat place on Kerbin. I made this aircraft based on real life commercial jet design. 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. Symmetry placement should give you perfect symmetry, as far as the game is concerned. LV-N has less than 25% of its full power at Kerbin sea level. The issue is my plane rolls very sharply to the left any time I pitch up. Thank you and happy landings. This ensures that your aircraft will go up once it achieves a high enough speed, and also helps with placing ailerons. Those and the fixed main gear are NOTORIOUSLY bouncy. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. The problem could be due to several issues. As such, you will need various control surfaces. 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. What you ought to be using is the Swept Wings and Elevon 1s instead of the Delta-Deluxe Winglets. ), Stable aircraft: "Untitled" (lost the file upon loading after aircraft), Stable jet car: "Untitled" (Lost the file), Speed over land > 350 m/s before veering off the runway, Sometimes Stable Spaceplane: "Hypersonic Experimental". Just like with rockets, get some courageous Kerbal in the cockpit and let's get started! Finally you need to make sure it's all balanced, this means the centre of lift marker needs to be very slightly behind the centre of mass marker. These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. I shouldn't have placed landing gears on the fuselage, I found that placing landing gears on flat surfaces like wings make landing gears a lot more stable. * Unlock steering and disable brakes on front gear. This thread is quite old. To slow down faster, you can increase the braking strength of your rear wheels. 2022 Take-Two Interactive Software, Inc. Make sure that all of your landing gears are pointing in exactly the same direction. 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. 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. It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. 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. They all had landing gear placed at the front and at the back. 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? It is also advisable to add some control surfaces to your plane to have some control in the atmosphere: you can manually add them to the wings or choose winglets with effective control surfaces, like the Standard Canard. Note: Your post will require moderator approval before it will be visible. Display as a link instead, One final point to consider is the mass you're planning to store in the fuselage. LV-N "Nerv" nuclear thermal rockets are commonly used on SSTOs for the rocket stage if Rapiers are not used. 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! Saves a lot of headache in wheels placement. Please consider starting a new thread rather than reviving this one. 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. Any plane needs speed - so you need thrust (usually). DO NOT ANGLE THEM! They sometimes coincide with ailerons on some, more space-economical, aircraft. Landing is hard. Control surfaces are heavier than wings. Also note that shock cone intakes appear to provide the best air supply at all mach speeds, and unlike other air intakes, they do not decline in performance beyond certain mach speeds. 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. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. For this to happen, I'm assuming you're using rocket fuel tanks. I'm making sure that I keep trying to get it up but it just wont go! - Have enough lift, either by a big wing area or high speed. However, they are extremely heavy for their power, weighing as much as a conventional rocket nearly 11 times more powerful. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. 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). All trademarks are property of their respective owners in the US and other countries. With initial passes, you start off with a periapsis at 50-60 km and gradually lower your apoapsis until you're in an almost circularized low orbit and then transition to your usual re-entry approach. This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. 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. 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. Try getting the wings to deflect the air down, either by lifting the front end up using canards or by mounting them at an angle using shift + wasdqe. 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. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. 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. You want an elevon on each set of wings. 3. angle of the wheels. 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. 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. (For test purposes, all aircraft are not pitched up and SAS is turned off. 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. Espaol - Latinoamrica (Spanish - Latin America), http://forum.kerbalspaceprogram.com/threads/65638-Basic-Airplane-Space-Plane-Aero-Tutorial. You could do it the kerbal way by attaching two SRBs to the nose of the plane pointing upwards. 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. Brakes in the back keep you stable. An altitude set to 18,000 meters tops off at 19,000 meters and drops to 15,700 meters . It is also said that a good landing is one you can walk away from. (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. 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. A control surface with 100% control surface portion will weigh twice as much as a wing with the same lift would weigh. Thermal turbulence, caused by convection, happens below clouds and typically only impacts planes during takeoff and landing. 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. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. . You can resolve the emergency by transferring fuel from rear fuel tanks to forward fuel tanks, but you should alter your design to bring your wings further back to prevent such incidents in the future. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. 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. You cannot paste images directly. Besides the good advice others have given, I would also be very careful with that little tailwheel. 6.4K Downloads Updated Jun 7, 2017 Created Jun 7, 2017. . Hit the launch button and watch your magnificent bird fly! When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. 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. In an aircraft with two or more engines, this can potentially cause you to enter a flat spin which can be unrecoverable if your center of mass is behind your center of lift. When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. To takeoff and land at low speed, it's helpful to rotate the wings so the leading edge is slightly above the trailing edge. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. You cannot paste images directly. That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. 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. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). If the problem has to do with lift then travelling very slowly, possibly even slower than that, should counteract the effects of lift and you won't drift nearly as much. Hello, I am having a small problem with a plane I have built. Valve Corporation. If you're planning on landing on a somewhat uneven surface, like an open grassland somewhere on Kerbin or an island on Laythe, consider packing some parachutes for deceleration. All rights reserved. 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? Create an account to follow your favorite communities and start taking part in conversations. Note that the lift rating does not mean that the wings will automatically lift a spaceplane into the air when it's moving forward. 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. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. Rapiers generally provide less thrust than a Whiplash at speeds below mach 2, but provide more thrust at higher speeds. 1. 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. So I started a new career file after not really playing for a long time and I'm now at the point where I just dropped 45 Science to unlocked Aviation to get some of the plane parts that I need. 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. 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 have built lots of spaceplanes. Easier just to bring the rear wheels closer as well as a in line reacton wheel. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa That, combined with a Unity joint bug, makes your plane bounce. 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. . Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. 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. Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. 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. They could go up to 120 m/s on the runway and still not lift up. In vanilla KSP, wings have a predefined lift factor. You can even try refueling it before recovering your spaceplane further increasing your recovering value. To minimize drag, vertical tail fins can be kept minimal, since aircraft can be maneuvered adequately by roll and pitch alone. Such as not producing lift, which is not what you want with a plane. 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. First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. This can easily cause you to crash on landing. Note: Your post will require moderator approval before it will be visible. They all had to use the runway drop to take off. How do I fix this? A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. i have no idea why this happens please help. 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. Even a small deviation can cause serious instability, making your aircraft bounce and jolt left and right even during takeoff. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. Remember how you want your center of lift/drag to be behind the center of gravity? There are multiple ways to place them: Ailerons control the roll of the aircraft, and are (almost) always placed on the wings, as far out as possible and as centered (compared to the center of mass) as could be. So I have played the game for 200 hours and I love it. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. * Gear not mounted to parts that will flex (e.g. Mk2 aircraft may be able to get away with it, but even then it's often best to space them further out. everytime i make a powered plane, it always flips over and points backwards after i take off. 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? So if I start encountering wobble it's time to pull back on the stick and get in the air. I don't have any mods but sometimes a problem may be a simple bug. 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. 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. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. That said, parachutes are an exceedingly effective means of reducing your stopping distance. Thanks for all the help. 5.whether the body you anchor the landing gears to are firm. Either put more engines or reduce the amount of rocket fuel. It is advised to place your control surfaces as far from your center of mass as possible. A good example of this is at the KSC runway when landing on a 90 degree bearing. They all had to use the runway drop to take off. As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. To avoid wobble, wheels need to be absolutely vertical, and they shouldn't be attached to something that is likely to flex as speed builds up, as this could also affect the vertical alignment. But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls. 2022 Take-Two Interactive Software, Inc. I have built lots of spaceplanes. This thread is archived . And also place them further apart. Some testing is usually required with new designs to determine the best ascent profile. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . 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. Be aware that landing on water is an option if your spaceplane can fly level at less than ~40-50 m/s. See if there is still a problem when only travelling slowly, say <20m/s. @TheEnvironmentalist There is one more method I'm sure would work in your case, although I didn't write about it because I think it's cheesy and wouldn't solve the root problem. This helped immensely and if you haven't been doing this already, do it. Although I usually only need 50 m/s for most planes to wobble out of control. 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. 2022 Take-Two Interactive Software, Inc. Slowly pitch up to avoid overheating. Flying a Space Station through a GAS GIANT! 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. Another trick is to move the rear landing gear forward, closer to the center of gravity. if its too far behind plane cannot lift. KSC's runway is slightly north of Kerbin's equator and perfectly flat.
