S5 moon rocket by lightbreaker_64. 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. Controllability of a plane is on you. This is for the same reason that you keep your fuel balanced. For a Mk1-based aircraft, your rear landing gears should not be tightly tucked together on the fuselage. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa Another trick is to move the rear landing gear forward, closer to the center of gravity. 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. Keep your nose pointed prograde as you descend through the atmosphere. Enable mirror symmetry to save yourself some alignment effort. All trademarks are property of their respective owners in the US and other countries. 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. Espaol - Latinoamrica (Spanish - Latin America), http://forum.kerbalspaceprogram.com/threads/65638-Basic-Airplane-Space-Plane-Aero-Tutorial. http://www.youtube.com/user/Cruzanak?. I dont really need 200m/s for take off. These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. Note: The large delta wing will ensure you won't backflip. 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. Powered by Invision Community. - SF. Take the large delta wings and place them on the aircraft. Whether you're storing your fuel in fuselage sections, wing sections, or attached inside of cargo bays, it's generally a good idea to keep equal amounts of fuel at equal distances from your center of mass. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. 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. Heavy Cargo Space Plane SSTO Download. 3. angle of the wheels. 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. (Idea is moot, if you haven't unlocked them yet.) Also avoid the basic fin for the same reason. This material may not be published, broadcast, rewritten, or redistributed. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. 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. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. 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. Depending on which surface you place them on, they might not be parallel to the axis in which case. Either put more engines or reduce the amount of rocket fuel. 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. Having said all that, these are the issues you must contend with. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. The plane is clearly unstable. I started investigating why this was happening. 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. Mk2 aircraft may be able to get away with it, but even then it's often best to space them further out. At that point, the plane could potentially start spinning around as a result of losing the benefit of the gimbal control of the engine. Make sure that all of your landing gears are pointing in exactly the same direction. Here's a quick installment in to the. All lift-rating means is that the wing section will resist motion perpendicular to its plane. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. To minimize the risk of such a situation, try to land on a large patch of flat open ground approaching a downhill slope. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. 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. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. You can deploy your chutes just prior to touchdown for rapid deceleration. Firstly you're going to want to make a short fuselage. I have built lots of spaceplanes. Thanks for the help guys. They are able to operate at higher altitudes and can even continue operating in a vacuum by switching to a rocket mode. 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. That, combined with a Unity joint bug, makes your plane bounce. Valve Corporation. To minimize drag, vertical tail fins can be kept minimal, since aircraft can be maneuvered adequately by roll and pitch alone. Throttle up to full, activate SAS, stage to start the engine (you'll only have one stage here), and start rolling (or sliding) down the runway! 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. Temperature tolerance is the primary consideration for fuselage choice. If there is, I would have found it long ago. Do you have a screenshot of the craft? All rights reserved. Is there a way to rectify this problem. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes. An aircraft without control surfaces is like a rocket without RCS or reaction wheels - it will hardly turn and will be equally hard to control (perhaps even impossible!). Mechjeb Spaceplane Guidance. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. 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. Upload or insert images from URL. 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? LV-N engines also have the advantage of using the same liquid for propellant that jet engines use for fuel. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! One idea I haven't noticed here yet: "wire up" the landing gear, with strut connectors. Privacy Policy. . I am definitely aware that there are multiple reasons as to why the plane flips. 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? Reddit and its partners use cookies and similar technologies to provide you with a better experience. Saves a lot of headache in wheels placement. 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. It provides a wider, more stable wheel base while keeping the wheels straight up and down (no camber). Clear editor. See if there is still a problem when only travelling slowly, say <20m/s. If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. Although I usually only need 50 m/s for most planes to wobble out of control. What you ought to be using is the Swept Wings and Elevon 1s instead of the Delta-Deluxe Winglets. 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. KSP Stock Space Shuttle by _ForgeUser18393701. 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. 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 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. 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. I also used Intake build aid to balance the intakes. Hit the launch button and watch your magnificent bird fly! 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. Display as a link instead, 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. I moved the back landing gear to right underneath the COM. If you've been able to successfully re-enter on previous low orbit test runs, you should be able to use this method to achieve similar rates of success once you've slowed down sufficiently. The problem could be due to several issues. 4. Powered by Invision Community. How do I fix this? Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. I have done everything imaginable to try to remedy this problem. Here is your convenient solution to this problem! I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft. 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. A control surface with 100% control surface portion will weigh twice as much as a wing with the same lift would weigh. Congratulations! It's strongly recommended to keep your landing gears well-spaced from each other to ensure that the aircraft will be difficult to roll into a collision. 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. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . 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. Does anybidy have any tips on how to build spaceplanes? The centre of mass was between the 2 landing gears. Even with a stable landing, you may find that you don't have enough room on your desired landing area to come to a stop before you reach the end. 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. Go on, and take the plane capsule which looks like a converted fuel storage device. as Shkeec said check gear check gear check gear. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. Tell ya what, I'm gonna try to recreate that thing in my sandbox and see what I get. As with everything in KSP, experiment, experiment, experiment. It is due to the spinning up of the engines. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. I took off and at 60 m/s I was in the air! When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. A Ravenspear Mk3 taking off from the Runway in version 1.0.5. It is also common to add an Inline Clamp-O-Tron, which, unlike all the other docking ports, can be placed in the middle of the spacecraft (a handy solution, since there is not much space at either end of the craft) to allow your plane to dock with space stations or other spacecrafts. They could go up to 120 m/s on the runway and still not lift up. 1. make sure your main gear is not wobbling (ie. 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. Pasted as rich text. A good example of this is at the KSC runway when landing on a 90 degree bearing. If your rear wheels are too far back the aircraft will not be able to pivot on the wheels and lift its nose up. 3. make sure your center of mass is slightly in front of center of lift force. 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. This makes design easier, eliminating all concern for balancing jet fuel against rocket fuel. 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. After placing wheels I always use the rotate gizmo on snap with absolute orientation. 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. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. 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. As lift increases you remove some strain on the gear, however you've just increased the amount of sag. * Unlock steering and disable brakes on front gear. You should be able to navigate fairly readily, and with the superb efficiency of jet engines, you should have plenty of fuel to go anywhere you need to go. The most dangerous part of a spaceplane flight is returning from orbit. For spaceplanes, avoid the FAT parts (wing, tail fin, and control surface). 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. 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. 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). Necessary for heavy/long spaceplane. 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. Here is your convenient solution to this problem! FOX 56 News Video More Videos I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. That will align with the craft axis. and our 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. If you have trouble pitching up enough to land at a reasonable speed, you can increase your maneuverability by toggling your flaps, canards and ailerons to greater than 100% control authority. If you have an account, sign in now to post with your account. 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. Press question mark to learn the rest of the keyboard shortcuts. Any plane needs speed - so you need thrust (usually). This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. Landing is hard. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why.
