How do you build a stable aircraft

12.1k BlackhattAircraft  6.1 years ago

I have played simpleplanes for about 4 years now and I have never, I my life, buit a stable plane. Ny that I mean a plane that doesn't have to much lift or to little lift. So I am asking this and I probably should have askes this a really long time ago, but I really need help with this and hopefully someone notices who knows what there talking about.

Thank you

    @BlackhattAircraft Naw, I just read a lot. There are kids on here that know way more than I do. The main takeaway is the more you can control the shape of the wing, the more things your plane can do.

    @BlackhattAircraft It is possible, but only for a specific circumstance. Wings turn speed into lift, so its a matter of the right amount of wing for the right speed. But wings are more than just lift, their shape determines how much speed you lose when you turn, how fast you can roll, all sorts of things. Besides, you don't want a plane that can only fly at one speed.

    That's why planes have so many devices to change the wings. Flaps, slats, root extensions, boundary layer blowers, swing wings, air fences. The list goes on.

    The way I handle it is I design the plane around its cruising speed, and try to balance the lift for that, then I use the trim tabs to adjust the lift from there. And of course flaps for takeoffs and landings

    @F104Deathtrap I know about the trim and I use it but I was wondering if it was possible

    No matter how hard you try you will never achieve this ex ept for a very specific speed at a very specific height. That's why planes have trim settings that allow you to adjust your lifting power to your speed and air density.

    TLDR: use trim tabs to keep your plane flying level.

    It's relatively easy, get the red line to be slightly in front of the blue line. Keep control surfaces as small as practical, put wheels where they are on real planes and not stupidly far back, keep wings an tail plane sizes proportional. If you want build something and tag me and I'll show you where you are going wrong
