i am building a little (no bigger than a foot) glider with a little motor. it is not going to go very fast so i need an aerofoil profile that works optimally at low speeds.
Induced drag(http://en.wikipedia.org/wiki/image:... on most aerofoils decreases with speed, and so that is my main problem. i need the best lift and the lowest induced drag at the lowest speed.
can you provide a link to a list of good aerofoils, or maybe provide (x,y) co-ordinates so i can plot it out.
i have come across a site, http://www.pdas.com/avd.htm... that has thousands of aerofoils in co-ordinate (x,y) form, but like i said, i dont know which one to use. thanks for any help.
