Flaps and slats. Questions and discussion

2,664 LotusEngineering  6.8 years ago

I've wanted to incorporate flaps and slats into my builds to make them more realistic performance wise.

How do you make flaps?

how do you (yes, YOU) use flaps in your creations and how do you make them work?

How do you make slats?

Slats, how do you make them? Do you use rotators, or something else?

Thanks!

    @LotusEngineering Let me know if there's any trouble, and don't bother making it a successor. Glad to be of help.

    @LotusEngineering Sure thing. The main wings of this Thunderchief feature those type of wing. Two green, two white sandwiched together. Just pull them off and reshape them. They're angled slightly anhedral, but you should be able to work around it. GOOD LUCK! https://www.simpleplanes.com/a/40G95H/F-105D-Thunderchief

    Is it possible you could send me one of those fancy xml structural wings? @F104Deathtrap

    Thanks! Maybe I'll download SP on my computer so I can do these fancy 'nudging' things@MrSilverWolf

    What I generally do is make the "fake" wing with the fuselage parts and then leave a spot open for the flaps to go in, then once I'm done with the wing I put a piston on the in them middle of the cut out spot for the flap, then I add a rotor to the end of the piston, usually I end up setting the rotor to only move 40 to 45°, then I make the flap when it's not connected to the plane, then I nudge the rotor more toward the back of the plane so when I add that flap part, it won't connect to the rest of the plane, then I nudge everything back into place, and finally nudge the rotor and piston back behind or if you like in front of the flap so when it is used it doesn't just rotate 45° in the middle, so it would properly go down and up, you can pick apart the wing on my AirWolf A365 and see what I'm talking about there if it helps, now idk how to do slats, also sorry for the wall of text

    Slats are a sort of flap, at the leading edge of a wing used to move to create more lift. @RailfanEthan

    Slats are another matter altogether, that would probably require rotors and additional wing panels to get them to look and function correctly.

    To construct main wings, I xml structural wings to allow control surfaces, then I create 2 control surfaces on each wing. The outer one I make roll (ailerons) the inner one I Xml mod to be VTOL (flaps). In real life, flaps only extend downwards, increasing lift, but allowing it to go both ways (unrealistically) simplifies trim control, so I usually keep it that way.

    Flaps: You can use rotators/hinges and fuselage blocks/structural wings OR .xml mod the input of already present control surfaces. I have no idea what slats are, though.
