The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. This material may not be published, broadcast, rewritten, or redistributed. They sometimes coincide with elevators. The Mk1 fuselage parts only tolerate up to 2000K, while Mk2 fuselages tolerate up to 2500K, and Mk3 fuselages tolerate up to 2700K. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. 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. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! 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. @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. Powered by Invision Community. Controllability of a plane is on you. 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. 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. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. I see absolutely no need to be traveling that fast down the runway. Your link has been automatically embedded. 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. 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. Obviously jet engines are air-breathing, so you need to include air intakes in your spaceplane. 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. Try not to place your gears to wings, especially wingtips - if they wobble even slightly, your plane lose the balance. 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. Plane - Kerbal Space Program Wiki 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. The issue is my plane rolls very sharply to the left any time I pitch up. LV-N has less than 25% of its full power at Kerbin sea level. Here is your convenient solution to this problem! It is also said that a good landing is one you can walk away from. These have an ISP of 800 in a vacuum which is significantly better than all other rocket motors except the very weak IX-6315 ion rocket. This would indicate two problems.

All rights reserved. #2 DaSkippa Mar 14, 2014 @ 2:56am as Shkeec said check gear check gear check gear. Note: Your post will require moderator approval before it will be visible. Control surfaces are heavier than wings. As such, you will need various control surfaces. Note: Some high-efficiency rocket engines lose most of their power and efficiency in low atmosphere. A control surface with 100% control surface portion will weigh twice as much as a wing with the same lift would weigh. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. The most dangerous part of a spaceplane flight is returning from orbit. 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? It provides a wider, more stable wheel base while keeping the wheels straight up and down (no camber). Here is your convenient solution to this problem! However, I want to place my wheels where i want to and not only on X parallel surfaces. You want an elevon on each set of wings. If you can maintain level flight at about 30-40 m/s, you should be able to perform an ocean landing if needed. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. To survive re-entry, it's recommended to start your approach back into the atmosphere at a shallow angle, ideally with a periapsis of around 30-35 km. They could go up to 120 m/s on the runway and still not lift up. My spaceplanes keep drifting off runway during takeoff. What am I doing Bit late i know, but i had the same problem. FOX 56 News Video More Videos my planes keep flipping backwards on take off : r/KerbalAcademy - reddit One final point to consider is the mass you're planning to store in the fuselage. 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. Espaol - Latinoamrica (Spanish - Latin America), http://forum.kerbalspaceprogram.com/threads/65638-Basic-Airplane-Space-Plane-Aero-Tutorial. Saves a lot of headache in wheels placement. Clear editor. I was attaining high speeds on the runway without getting off the ground, which made the plane yaw back and forth. When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. Espaol - Latinoamrica (Spanish - Latin America), http://steamcommunity.com/sharedfiles/filedetails/?id=484107795, http://steamcommunity.com/sharedfiles/filedetails/?id=484107807, http://steamcommunity.com/sharedfiles/filedetails/?id=484107735, http://steamcommunity.com/sharedfiles/filedetails/?id=484107761, http://steamcommunity.com/sharedfiles/filedetails/?id=484119427, http://forum.kerbalspaceprogram.com/threads/52080-Basic-Aircraft-Design-Explained-Simply-With-Pictures, http://steamcommunity.com/sharedfiles/filedetails/?id=484137556, http://images.akamai.steamusercontent.com/ugc/443953434412162923/42B3BB54A6A524CCC2E5C102AD88C8E521790F55/. To minimize drag, vertical tail fins can be kept minimal, since aircraft can be maneuvered adequately by roll and pitch alone. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. 67K subscribers in the KerbalAcademy community. 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. This can easily cause you to crash on landing. All I have are the parts from the Aerodynamics tech and the gear bay (wheels). 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. In vanilla KSP, wings have a predefined lift factor. If you have an account, sign in now to post with your account. I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. Spaceplanes generally ascend best on a 10-30 degree incline, often leveling out towards higher altitudes to pick up the maximum horizontal velocity before switching to rocket motors. Why does my plane roll left on takeoff : r/KerbalSpaceProgram - reddit Also, excessive use of the rudder usually causes the plane to spin out of control and crash. Temperature tolerance is the primary consideration for fuselage choice. 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. 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. Note: This tutorial was last updated for version 1.7.2. Valve Corporation. 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). Similar principles apply when finding suitable landing sites away from the KSC. 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. S5 moon rocket by lightbreaker_64. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Plane bouncing on takeoff - Kerbal Space Program Forums I removed them and it works fine now. 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. Then this tutorial is for you. This plane will be able to take off, travel somewhere, perform a crew report, and then land. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. Keep at around 15 degrees to allow the plane to accelerate past 1000m/s. 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. Slowly pitch up to avoid overheating. I'm making sure that I keep trying to get it up but it just wont go! Necessary for heavy/long spaceplane. Now imagine what happens like that. Pasted as rich text. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. The reverse also happens. 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. 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. 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. Need to move them up. If there is, I would have found it long ago. Such flight involves lift-induced drag, but reduces the total thrust required to traverse a distance at a given speed. 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. LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. Having said all that, these are the issues you must contend with. KSP short takeoff plane test | Simple Horten Ho 229 replica 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. 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! Heavy transport seaplane inspired to the Soviet Beriev A-40 Albatros which also appears in Evangelion 2.0! All the weight is pushed on the middle and it can't pull up. 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. My plane usually take off at a little over 120m/s. I have also thought about a wider base. Do you have a screenshot of the craft? I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft. Please consider starting a new thread rather than reviving this one. For more information, please see our 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. Install S5 moon rocket By lightbreaker_64. 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. You want to get up to get the gear tucked away and reduce drag. You cannot paste images directly. [KSP] - Heavy Seaplane Take-off, Water-landing and Re-take-off! 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. 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! 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? (Idea is moot, if you haven't unlocked them yet.) Go on, and take the plane capsule which looks like a converted fuel storage device. Your previous content has been restored. 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. 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. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. Tutorial: Your First Plane - Kerbal Space Program Wiki That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. You can deploy your chutes just prior to touchdown for rapid deceleration. This ensures that your aircraft will go up once it achieves a high enough speed, and also helps with placing ailerons. If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. 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. Your very own tutorial.). This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. 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. Everything looks perfectly symmetrical as far as I can tell. These should be in the bottom left next to the display of the cost of the aircraft. 4. 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 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. This thread is quite old. Next you need landing gear. (Source). An altitude set to 18,000 meters tops off at 19,000 meters and drops to 15,700 meters . Powered by Invision Community. KSP Stock Space Shuttle by _ForgeUser18393701. I started investigating why this was happening. A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. 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. Tutorial: Basic Plane Design - Kerbal Space Program Wiki * Unlock steering and disable brakes on front gear. 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. 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! It's said that takeoffs are optional but landings are mandatory. How to make aircraft take off - Kerbal Space Program Forums 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. This plane will be able to take off, travel somewhere, perform a crew report, and then land. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. 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. You want to start by attaching a Mk 0 Liquid Fuel Tank under the wings, making sure you're mirrored so it goes under both wings. Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. I can not get any aircraft-style spaceplane take off from the runway, they will stay on until the end, where the engines crash into the ground and explode. 2022 Take-Two Interactive Software, Inc. my planes keep flipping backwards on take off . My Space Plane Keeps Flipping Backwards On The Runway. This is also the same reason why planes start rolling toward the middle of the runway; because both ends of the runway are further from the center of Kerbin than the middle (because it's totally flat), the runway is a valley from a gravitational frame of reference. That's over 2x the normal recommended max. Remember how you want your center of lift/drag to be behind the center of gravity? I moved the back landing gear to right underneath the COM. 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. This page was last edited on 19 February 2020, at 07:08. Paste as plain text instead, So I have played the game for 200 hours and I love it. Plane bouncing on takeoff - Gameplay Questions and Tutorials - Kerbal Space Program Forums 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. First try speed over land reached over 210 m/s before flipping in the last second. And above all: have fun! 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. All rights reserved. Flying a Space Station through a GAS GIANT! Consider placing your rear landing gears close to the spaceplane's center of mass, but be careful to avoid an engine collision with the runway. Does anybidy have any tips on how to build spaceplanes? But be careful and don't crash it! How do I fix this? However, they are extremely heavy for their power, weighing as much as a conventional rocket nearly 11 times more powerful. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. 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. Some testing is usually required with new designs to determine the best ascent profile. How to keep an airplane stable on the runway in Kerbal Space - Arqade For heavy rockets, it might be required to use structure to space the gears away from the body to allow more pitch.
