"Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. 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. You could do it the kerbal way by attaching two SRBs to the nose of the plane pointing upwards. All of them had one thing in common though. 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. 2. 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. For spaceplanes, avoid the FAT parts (wing, tail fin, and control surface). Pasted as rich text. 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. The Kerbal Space Program subreddit. KSP Stock Space Shuttle by _ForgeUser18393701. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. This helps to keep the performance of your spaceplane stable with any amount of fuel. Here is the best aircraft I have created to date: Jet Aircraft. Landing is hard. Works well on small craft. All of these problems can be exacerbated or reduced by adjusting the amount of fuel in your tanks during landing. For more information, please see our You should have something called an "Elevon 1"; this will be the moving part for your wings. They sometimes coincide with ailerons on some, more space-economical, aircraft. * Gear not mounted to parts that will flex (e.g. To takeoff and land at low speed, it's helpful to rotate the wings so the leading edge is slightly above the trailing edge. Clear editor. As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. Do you have a screenshot of the craft? 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. Easier just to bring the rear wheels closer as well as a in line reacton wheel. For all your gaming related, space exploration needs. A good example of this is at the KSC runway when landing on a 90 degree bearing. 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. 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. This page was last edited on 19 February 2020, at 07:08. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Necessary for heavy/long spaceplane. Or adding a RATO boosters. 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. Ideally, the wings should be tilted upward at an angle about 3-5 from the fuselage for optimal lift-to-drag ratio.[1]. 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! 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. Let it get good and clear of the ground before applying any control to it. Your wheels should now have 0 degree angle between them, meaning they are both. LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. All trademarks are property of their respective owners in the US and other countries. here are some images and a gif. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. FOX 56 News Video More Videos I'm making sure that I keep trying to get it up but it just wont go! the I place on the wing and attach landing gear on those, it sometimes takes a few tries to find the right spot but well worth it. They are able to operate at higher altitudes and can even continue operating in a vacuum by switching to a rocket mode. everytime i make a powered plane, it always flips over and points backwards after i take off. Even if you can takeoff, landing will usually destroy tat aircraft so survival rate on an aircraft for a typical kerbal is nearly zero. 5.whether the body you anchor the landing gears to are firm. The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. 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! You want an elevon on each set of wings. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). Slowly pitch up to avoid overheating. For this to happen, I'm assuming you're using rocket fuel tanks. Now stick a jet engine on the back, and don't forget to put an air intake or other air-sucking device (you can find them in aerodynamics) on the airplane. (Sorry For Poor Image Quality) : r/KerbalAcademy 385 votes, 49 comments. Canards and horizontal tail fins should be placed as far towards the front and back of your aircraft as possible, respectively. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. 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. That's over 2x the normal recommended max. 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. 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. Safety note: Disable the brakes on the front landing gear. 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. So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes. It Flips Up And Towards The Opposite Direction. This is for the same reason that you keep your fuel balanced. I have never successfully landed a single aircraft before as they all tend to roll over when landing at high speed. (Yes, you personally, you lucky thing! This helped immensely and if you haven't been doing this already, do it. Flying a Space Station through a GAS GIANT! Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. I don't have any mods but sometimes a problem may be a simple bug. If you need to carry more fuel, consider using the Big-S Delta Wing as it provides the same lift-to-drag and lift-to-weight ratio as any other wing of the same mass, yet has the ability to carry fuel as well. 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. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. 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. 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. Here, the. wings, unless they're very well braced). Install S5 moon rocket By lightbreaker_64. That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. 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. KSP handling death investigation High Winds Cause Widespread Power Outages Ohio . If you have an account, sign in now to post with your account. And, of course, try to take off and land as slow as possible. Unstable Aircraft: "FAR Firehound" (Stock). Display as a link instead, Ideally, you ought to test landing the spaceplane with full fuel tanks and with nearly empty fuel tanks prior to taking your spaceplane to orbit. 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. It is also said that a good landing is one you can walk away from. 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. Your previous content has been restored. 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. This would indicate two problems. First try speed over land reached over 210 m/s before flipping in the last second. Notice how the landing gears are placed out on the wings. First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. Maybe ;making the tailwheel less stiff would help, too. Paste as plain text instead, Note that no wings will tolerate more than 2400K, so the difference in temperature tolerance between Mk2 and Mk3 fuselages isn't terribly significant. I made a KSP replica of the Horten Ho 229 while trying to make a short takeoff plane.If you have any questions or suggestions, let me know in the comments.My. 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. As lift increases you remove some strain on the gear, however you've just increased the amount of sag. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. 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. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. Those and the fixed main gear are NOTORIOUSLY bouncy. 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. Some testing is usually required with new designs to determine the best ascent profile. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. Here is your convenient solution to this problem! 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. This can easily cause you to crash on landing. 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. I see absolutely no need to be traveling that fast down the runway. Brakes in the back keep you stable. My plane usually take off at a little over 120m/s. Note: This tutorial was last updated for version 1.7.2. Heavy transport seaplane inspired to the Soviet Beriev A-40 Albatros which also appears in Evangelion 2.0! 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! - KSP Matt Lowne 527K subscribers 1.3M views 2 years ago I've wanted. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Lift maxes out at 30 and declines beyond that point, so avoid excessive fuselage tilt.[1]. 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. 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. 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. 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. Basic structure Firstly you're going to want to make a short fuselage. Second try, speed over land reached over 210 m/s and it didn't flip. 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 Center of Mass and Center of Lift are the usual causes of instability. 3. make sure your center of mass is slightly in front of center of lift force. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. as Shkeec said check gear check gear check gear. I dont really need 200m/s for take off. Just after having taken off, the plane will immediately start rolling to the right, and completely uncontrollably. 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. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. You cannot paste images directly. All rights reserved. Display as a link instead, And above all: have fun! 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. ), 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". Even a small deviation can cause serious instability, making your aircraft bounce and jolt left and right even during takeoff. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. They all had to use the runway drop to take off. I removed them and it works fine now. And also place them further apart. Upload or insert images from URL. Alternatively, if you're returning from a high orbit or from an interplanetary trip, you can try repeated shallow passes through the atmosphere. It's a prolem enough I have sever differen gear subassemblies that are stable (un wobbly) I can then position depending on COM. Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. It is advised to place your control surfaces as far from your center of mass as possible. Now imagine what happens like that. 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. The most dangerous part of a spaceplane flight is returning from orbit. This thread is archived . 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). However, they are extremely heavy for their power, weighing as much as a conventional rocket nearly 11 times more powerful. If there is, I would have found it long ago. This plane will be able to take off, travel somewhere, perform a crew report, and then land. Then at the top, we'll put one tail fin, centred on the end of the fuselage. Place your rear wheels/gear in front of the flaps on your wings. 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. if mounted on not struted part) 2. put your main gear slightly behind center of mass. Note: The large delta wing will ensure you won't backflip. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. 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. You can also angle the wings themselves slightly upwards (using WASDQE) in order to make them generate more lift when horizontal. 67K subscribers in the KerbalAcademy community. 4. 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. See if there is still a problem when only travelling slowly, say <20m/s. If you keep all of the fuel in the front, you may find that your center of mass drifts backwards as your fuel drains. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. For a Mk1-based aircraft, your rear landing gears should not be tightly tucked together on the fuselage. Consequently, atmospheric reentry is less dangerous with a Mk2 or Mk3 fuselage, compared to reentry with Mk1 fuselages. 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. However, I want to place my wheels where i want to and not only on X parallel surfaces. 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? 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. Press question mark to learn the rest of the keyboard shortcuts. This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. 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). 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. I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft. Paste as plain text instead, I was wrong. If your rear wheels are too far back the aircraft will not be able to pivot on the wheels and lift its nose up. 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). You're going to have a bad time. But, likely guess is your craft is not producing enough lift. Temperature tolerance is the primary consideration for fuselage choice. They sometimes coincide with elevators. (Source). 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. Note: Your post will require moderator approval before it will be visible. Congratulations! These have extremely poor temperature tolerance and will almost inevitably break up during atmospheric reentry. 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. You can even try refueling it before recovering your spaceplane further increasing your recovering value. if its too far behind plane cannot lift. 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? 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. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. Edit: I made a simple easy plane in career mode that is both stable and cheap: A trick i've used before is to put modular girders on the sides of the fuselage and putting the gear on the bottom of the girders. But also check to make sure that your wheels are placed symmetrically and your engines are aligned properly. This can turn into a fatal scenario if the center of mass gets behind the center of lift and you enter a flat spin. Yours is a very light plane, and the standard suspension settings are for a medium heavy plane -- so your suspension is too stiff. https://forum.kerbalspaceprogram.com/index.php?/topic/124380-wing-lift-amp-wing-lift-to-drag-ratio-charts/, https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Spaceplane_basics&oldid=100619. Angled landing gear create rotational force for whatever reason. For myself, it always was the position of landing gear in terms of pitch. #2 DaSkippa Mar 14, 2014 @ 2:56am as Shkeec said check gear check gear check gear. 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. 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). 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. 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. Nothing bad will happen. 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. 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. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. i have no idea why this happens please help. I have built lots of spaceplanes. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. S5 moon rocket by lightbreaker_64. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . That will align with the craft axis. 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. 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. This aircraft handles smoothly, no matter how you turn, roll and flip this aircraft, it will never lose control. Espaol - Latinoamrica (Spanish - Latin America), http://forum.kerbalspaceprogram.com/threads/65638-Basic-Airplane-Space-Plane-Aero-Tutorial. Do you have new pics after you moved the rear wheels forward? 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. My Space Plane Keeps Flipping Backwards On The Runway. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. Powered by Invision Community. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. 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. They could go up to 120 m/s on the runway and still not lift up. Powered by Invision Community. Wow, if you need 200 m\s to take off, you should think about adding more lift. You can also use parachutes on landing, but care must be taken to ensure that an adequate length of runway remains since you'll only get one chance to use them. Cookie Notice When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. 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. This thread is quite old. 2022 Take-Two Interactive Software, Inc. 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. You probably won't have much luck landing the fuselage intact if your Mk3 plane gets its wings scorched off on reentry.
