All lift-rating means is that the wing section will resist motion perpendicular to its plane. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. 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! 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 that's not an option, you can still recover some value by landing at any suitable flat place on Kerbin. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Similar principles apply when finding suitable landing sites away from the KSC. 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.

When your nose is stable at about 10 degrees above the horizon, pull up hard and keep it pulled. How wide is the base. When gear is placed, it has just one point of attachment. Valve Corporation. Here's a quick installment in to the. Try not to place your gears to wings, especially wingtips - if they wobble even slightly, your plane lose the balance. I have also thought about a wider base. Here, the. Valve Corporation. Note that no wings will tolerate more than 2400K, so the difference in temperature tolerance between Mk2 and Mk3 fuselages isn't terribly significant. That will align with the craft axis. I don't have any mods but sometimes a problem may be a simple bug. (Source). Powered by Invision Community. Re-entry heating can destroy parts of your spaceplane, or destroy it entirely. So if I start encountering wobble it's time to pull back on the stick and get in the air. These should be in the bottom left next to the display of the cost of the aircraft. Now for the engines. You can either go with four "LY-O1 Fixed" or a tricycle of two LY-01 near the back and one "LY-05 Steerable" at the front; either is fine for now.
Temperature tolerance is the primary consideration for fuselage choice. Hello, I am having a small problem with a plane I have built. 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. 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 just thought my planes were too heavy or not enough control surfaces. Thanks for everyone trying to help! A relatively low-drag alternative is to use an inverted cargo bay and some hydraulic cylinders with structural panels as a cargo elevator. 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/. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. everytime i make a powered plane, it always flips over and points backwards after i take off. That said, parachutes are an exceedingly effective means of reducing your stopping distance. EDIT: So, I set the front landing gear spring and damper to 0.5, and also set the tail gear spring and damper to 2, and the problem was fixed! Tell ya what, I'm gonna try to recreate that thing in my sandbox and see what I get. 2022 Take-Two Interactive Software, Inc. 2022 Take-Two Interactive Software, Inc. All trademarks are property of their respective owners in the US and other countries. Note: Some high-efficiency rocket engines lose most of their power and efficiency in low atmosphere. First of all, since the launch happens horizontally, you will have to include landing gears, and you will most likely want to include jet engines for the first stage for excellent fuel and cost efficiency.
How to keep an airplane stable on the runway in Kerbal Space - Arqade 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. 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? You main problem is your landing gear. 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. 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. 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). 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. This page was last edited on 17 December 2021, at 13:14. KSP 2 speculation: I believe terraforming will be a feature of the game. If you have an account, sign in now to post with your account. 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.
Plane spins/lurches to the side during takeoff? :: Kerbal Space Program LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. 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). 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). Does anybidy have any tips on how to build spaceplanes? Thank you and happy landings. If, instead, all goes well, then once your jet engines have shut down you will need to start the second part of your space mission by switching to rockets. 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 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. If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off.
Planes and Ships - Shareables - Kerbal Space Program - CurseForge This makes them a very effective choice for SSTOs since they do a good job of getting maximum velocity out of air-breathing mode, and then allow you to use oxidizer without needing the added weight and drag of a separate rocket engine.
Tutorial: Your First Plane - Kerbal Space Program Wiki I worked through the tutorials and I think my problem was most often a lack of lift, or perhaps more accurately sufficient control surfaces. 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). 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. - SF. When I use it for spaceplane guidance it keeps me on the correct heading, but the flight is very busy sine wave of a path. You cannot paste images directly.
What causes turbulence? | WOWK 13 News Install S5 moon rocket By lightbreaker_64. 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. Cookie Notice 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. 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. You can post now and register later. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. 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 subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. 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. KSP v.22 Takeoff Troubleshooting Guide/Tutorial Lots of info to help get your plane off the runway! 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. - Have enough lift, either by a big wing area or high speed. To slow down faster, you can increase the braking strength of your rear wheels. @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. 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. In vanilla KSP, wings have a predefined lift factor. 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. Here is your convenient solution to this problem! Your wheels should now have 0 degree angle between them, meaning they are both. This plane will be able to take off, travel somewhere, perform a crew report, and then land. Be warned that if you do not provide sufficient air intakes for the engines you've placed, you may find that some of your engines shut down before others. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! 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!). Note: Your post will require moderator approval before it will be visible. My first test of the plane parts in KSP2.Like and Subscribe for more Kerbal stuffs!#kerbalspaceprogram #ksp2 #kerbalspaceprogram2 #shorts #spaceplane #nasa 1. tilt of the plane. Even a small deviation can cause serious instability, making your aircraft bounce and jolt left and right even during takeoff. 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. 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. wings, unless they're very well braced). This thread is quite old. 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. They could go up to 120 m/s on the runway and still not lift up. my center of lift is always slightly infront of my mass. here are some images and a gif. Or adding a RATO boosters.
My plane won't take off :: Kerbal Space Program - Steam Community 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. Nothing bad will happen. Notice how the landing gears are placed out on the wings. However, they are extremely heavy for their power, weighing as much as a conventional rocket nearly 11 times more powerful. I removed them and it works fine now. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . Upload or insert images from URL. 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. This is an important distinction; a plane with great lift rating but without any control surfaces will fly easily but will be almost uncontrollable. I was wrong. You can deploy your chutes just prior to touchdown for rapid deceleration. 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. All the weight is pushed on the middle and it can't pull up. And also place them further apart. Geometric shape of the body you attach the landing gear to. But be careful and don't crash it! Either put more engines or reduce the amount of rocket fuel. Cure: Draw a mental axis from the nose to the tail of the plane and use the rotate tool (summetry on), on one of the wheels. Controllability of a plane is on you. Let it get good and clear of the ground before applying any control to it. They could go up to 120 m/s on the runway and still not lift up. 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. Thermal turbulence, caused by convection, happens below clouds and typically only impacts planes during takeoff and landing. 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? But I am still not sure if there are more reasons or perhaps it is just a physics bug which I am wasting my time on. I have found a solution to my problem. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. Safety note: Disable the brakes on the front landing gear. Now imagine what happens like that. I do add a strut to each wheel out of habit since my earlier versions use to roll, better safe than sorry. symmetry building makes them face slightly towards (or away from) each other, with wobbly results. Besides the good advice others have given, I would also be very careful with that little tailwheel. 2022 Take-Two Interactive Software, Inc. and our Thanks for the help guys. Brakes in the back keep you stable. Your link has been automatically embedded. Descending greater than -10 m/s usually makes a mess. 4. The reverse also happens. I have doubled the max stress value for aerodynamics failure in FAR for every category. While I am not a great plane builder there is a part in the structural (I think it is a pylon?) 200 m/s runway stability just doesn't seem to have a worthwhile purpose to me, and is inducing counter productive engineering challenges. If you are using B9 Rocketery or other parts that utilize Firesplitter, this is normal. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. 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. How do I fix this? Wing shapes do not appear to have a significant impact on drag or drag-to-lift ratio at this time, but swept wings are still an easy way to help ensure that your center of lift stays behind your center of mass. An alternative is making sure you have complete control of the craft. If your aircraft is burning up during this stage, you may need larger wings to slow you down faster, radiator panels to carry away the heat more effectively, parts with a higher temperature tolerance (like the Mk2 liquid fuel fuselage instead of the Mk1 liquid fuel fuselage), or parts to increase your maneuverability, like RCS thrusters, reaction wheels, or canards and elevons. Create an account to follow your favorite communities and start taking part in conversations. 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. Please consider starting a new thread rather than reviving this one. 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. I just thought my planes were too heavy or not enough control surfaces. Why is it doing this? After externsive testing and bloodpressure rise, results: it doesnt matter where you place the wheels, as long as they are not angled on the X (nose-tail) axis. Slowly pitch up to avoid overheating. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. KSC's runway is slightly north of Kerbin's equator and perfectly flat. 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! Is there a way to rectify this problem. You want an elevon on each set of wings. The issue is my plane rolls very sharply to the left any time I pitch up.
Mechjeb Spaceplane Guidance : r/KerbalSpaceProgram - reddit Does your plane never pull up taking off? I have been building - reddit 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. 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. It is advised to place your control surfaces as far from your center of mass as possible. 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 plane will be able to take off, travel somewhere, perform a crew report, and then land. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. Place your rear wheels/gear in front of the flaps on your wings. As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. Having said all that, these are the issues you must contend with. Such flight involves lift-induced drag, but reduces the total thrust required to traverse a distance at a given speed. So I have played the game for 200 hours and I love it. You cannot paste images directly. Clear editor. Paste as plain text instead, as Shkeec said check gear check gear check gear. . 3. angle of the wheels. T-1 "Dart" engines are unique amongst conventionally-fuelled rocket engines: They have close to the highest efficiency in both vacuum and low atmosphere. I started investigating why this was happening. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. . This material may not be published, broadcast, rewritten, or redistributed. If you can give a craft file and a mod list I could take a look. 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. 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. This is all right if their high efficiency saves enough fuel, but that may not be the case in small spaceplanes with limited fuel capacity. Heavy transport seaplane inspired to the Soviet Beriev A-40 Albatros which also appears in Evangelion 2.0! It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. 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. Note: The large delta wing will ensure you won't backflip. 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). Take the large delta wings and place them on the aircraft. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. Suggest a Correction Copyright 2023 Nexstar Media Inc. All rights reserved. Landing is hard. This is starting to get really frustrating. 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. 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.
KSP 2 || First Plane Take-off || Kerbal Space Program 2 DO NOT ANGLE THEM! Keep at around 15 degrees to allow the plane to accelerate past 1000m/s.

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. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 . Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. All of them had one thing in common though. 67K subscribers in the KerbalAcademy community. As such, you may want to line all forward Mk1 radial nodes on your aircraft with shock cones, if possible.
