It's unlikely you're doing this but just in case: while on the ground use only yaw controls to change direction, don't touch the roll controls. Also: high proportion of lifting surfaces to non-lifting surfaces. Also there it's important to place small landing gear after setting up CoL to CoM relation since it's mass is calculated in CoM in SPH/VAB but not counted in flight. In other words classic tripod. 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). Is it even possible to have a practicalVTOLcraft without using the unlimited fuel cheat? there aren't any aerodynamics when you are a kraken scientist like me. My Hats off to Brikoleur, as a fellow VTOL/general spaceplane [stock] enthusiast, your tips were easy to read and right on the money! Plane body deformations can cause the wheels to touch the ground at a slightly different angle. You need enough intakes to keep them fed. When your airspeed is near zero and you're above your landing spot, reduce throttle until you start descending. A basic tutorial on building a single prop plane. if that does not work, lower the spring strength until it works properly. Also stock fuel priority is in 1.2, allowing very stable CoM builds. Sorry if this is just too basic, it is kind of for beginners, edit: [snipped the stupid thought] i need to stop trying to post when dead tired, I like rules of thumb like these All the info you need without getting bogged down with specifics, Just a quick FYI, you say that CoL is center of thrust and CoT is center of lift; these are the wrong way around. Can't remember where I saw/read about it - Scott Manley maybe? Ill edit this sometime this week. First off, make whatever you want, just, start off making sense. What is Wario dropping at the end of Super Mario Land 2 and why? Kerbal Space Program, how do you disable autosave? You can post now and register later. It may be too far forward, especially if the tail is too small relative to the plane's wings. I'm going to strongly suggest using the angle set to 90 degrees + symmetry mode to place landing gears. They optimize use of oxidizer in SSTOs. If it doesn't, he can just make the stabilizer bigger; instead of turning down control authority, just add more fixed wing. Eventually you either crash, or you reach a high enough speed that SAS wiggling can't cause a significant enough difference in engine speeds. RCS will get the job done nicely, and looks cool to boot. Control your vector primarily with pitch, and your descent rate with throttle. How do I build a good stable basic plane? Now stick a jet engine on the back, and don't forget to put an . The CoL should be in the center or just behind the CoM. A slight "inwards" tilt on your wings (5 degrees or less) will improve stability hugely and will cause your plane to slowly correct itself in flight, also if you're using large control surfaces at high speeds then the result is obvious. Does the order of validations and MAC with clear text matter? Your previous content has been restored. LTTP again (KSP on hiatus for a bit), but here's an answer anyway. Plane - Kerbal Space Program Wiki All rights reserved. Go on, and take the plane capsule which looks like a converted fuel storage device. Such a simple and basic tip, but so unknown throughout KSP. I have also used rocket-powered VTOLs on Duna. A Screenshot of Kerbal Space Program. Now, get a pair of winglets, and place them at the front of the plane to get that approximate spacing of COM . Build yourself a plane. what do you mean by "wheels are mounted with angle snapping"? https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. 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? Can I use the spell Immovable Object to create a castle which floats above the clouds? And start small. Of course the cargo capacity is less than with a HTOL since you're using some of it to haul those vertical thrusters. What Trump's very stable geniuses lack in intelligence they more than make up for in confidence. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. In particular, there's one constraint that needs special attention: centre of mass, and the invariance thereof, as you burn fuel. If you have more than one engine, you can get asymmetric thrust at low speeds. Intriguingly, there is one thing I've found that does prevent the wobble from starting, and that is to use a single engine mounted directly on the back of the fuselage, which prevents using a tail and is ultimately a fairly significant restriction to build around. When off the ground at a sufficient altitude to clear obstacles, main jets ON, When at sufficient speed for aerodynamic flight, hoverjets OFF, pods CLOSED, gear UP. ps: use caps lock(fine control) to reduce the amount you're actually moving the control surfaces. Why did DOS-based Windows require HIMEM.SYS to boot? Put the big wings right at the back of the plane. Some general pointers to make more stable aircraft, one is to set your COL just behind your COM, another is that your centre of drag should be as far back as possible - there's no way to visually show this as far as I know but a light but aerodynamically bulky rear to an aircraft generally makes it more stable. Simply changing the intakes made it fly completely out of control and impossible to land. jet engine efficiency in this game is based on built in thrust curves. Body deformation can be caused by heavy parts, many parts connected together, or forces on the plane. 2) Then add the pitch control surfaces. zombie2u, All rights reserved.

Haha I think Ive perfected an aestheticallyclean turbine jet VTOL USAF F-35b Lightning II2020 https://imgur.com/gallery/918HyM4 https://imgur.com/gallery/f0NDJxR. They have in common that it's easy to tweak the balance by moving things around, rather than having to add or remove pieces. - but they were talking about having two intakes/engine. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). For what it's worth - watching 1.2 pre-release streams, the upcoming changes to SAS are profound. Next question? So the ones that go straight up and down can only be straight up and down, no angling left, right, backwards or forwards such as when you place the little wheel on the angled body of the cockpit part. Somebody figured out how to make a stable orbit inside of the atmosphere Scan this QR code to download the app now. The absurdly big wing and control surfaces make it highly economical for high-altitude supercruising. The more intakes added, the higher a plane can go before a flame-out, which makes multiple intakes a must on SSTO spaceplanes. 19000m. 1) Before adding your pitch control surfaces, move the main wing to make sure that CoM is very very slightly in front of CoL, or exactly on the same spot (if you want more maneuverability). It is certainly possible to make VTOLs that can circumnavigate the planet. This is my current best hi alt plane. I'm trying to build a high altitude plane and have found out that the rules are different. 3. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. I've been playing around with aircraft over the past couple days, only to find that no matter how low I set the pitch authority, they tumble and crash at the slightest hold of the "S" key. If the CoM is in the back, then it will ALWAYS not be able to get out of a stall, flatspin all the time, and will be an all around horrible plane. I decided to look into that two intakes thing, and it turns out to make 11-12 m/s difference at 19,000m with my plane. one last thing to verify: look from the side, observe where your center of mass is, then how the control surfaces are located relative to it and if the way they react to your controls makes sense (just try to pull up, down, or roll, on the runway without even starting the engine or disengaging brakes and watch which way the control surfaces move). - SF. Use Pilot Assistant - it's SAS is meant for aircraft rather than general ( read: rocket ) use. You need to sign in or create an account to do that. You would need to get down into the 37k-45k zone to aerobrake enough to come down in one orbit. I used the angle snapping feature (to the right of the symmetry selector in the bottom left hand corner of the screen in the space plane hangar view) to mount the steerable wheel perpendicular to the ground, and the two fixed wheels symmetrically such that zoomed in, the wheels themselves are perpendicular, though the fixed wheel part itself comes with something like a 45 degree angle between the wheel and the shaft that attaches it to the craft, so the shafts naturally sit at something like a 45 degree angle out to either side so the wheels can sit perpendicular. Somebody figured out how to make a stable orbit inside of the - Reddit Please consider starting a new thread rather than reviving this one. Your previous content has been restored. So thanks for the pointers - I'll take a look (and try to cure my prejudice re canards). They'll still happen but you'll have more time to get off the ground. 4. 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!). You're one of the few I've read that recognized the potential of Junos in vtol vs the more popular panthers or using rotating clamp-o-tron assemblies- bigger engines have the huge design downside of shifting COM above fuselage longitudinal axis, which makes rocket placement difficult for SSTOs.
