bluefox;

I believe that in order to get any kind of useful answer you will need to provide more information like required RPM at the generator shaft, wind speed at your site as well as expected power at the minimum. Not the kind of thing where one size fits all.

Good Luck.

Re=300 000

u/v=6

v=6-8 m/s

D=2*R=2 m

blade = 2* [wood]

airfoil( BE50S, CLARKY, NACA 2414, anderson spica, .......) ??

Every body uses NACA 4412 but it´s good for Re>1000 000

Thank
