Hi,
(I've read a few Wikipedia articles about flight, so I know almost nothing about flight.)
I'm trying to help a friend design a ground effect vehicle for over the water.
That's an ambitious goal, so I'd first like to design a stable, LOW speed aircraft.
Even that's an ambitious goal, so I'd like first to design a Styrofoam kite version of this.
So I'd like to design a kite from Styrofoam that looks like an airplane, that flies level no matter what, and generates lift in low winds (and not much more in higher winds) (That I can tow behind my car/bicycle.)
From my reading of Wikipedia, I understand that I need to have a low wing loading, and a high aspect ratio (to me these things seem mutually exclusive). Adding a canard wing in the front also adds stability.
(I've also seen designs specifically designed for exploiting the ground effect, but these I think, need to fly too low to be practical, so I'd rather go for a design that is efficient at ALL flight altitudes, like a glider. A glider also might be relatively less affected by the negative consequences (flipping backwards) of the ground effect.)
I haven't yet found what the best angle of attack of the wings is in low speeds?
What is the best angle of attack if I want the airplane to have the maximum lift in 30-50 mph (45-75 km/ph)? (Disregarding drag)
