Hi,
I'm going to redesign my turbine's fin, and change it to an aerodynamic shape.
This is my previous design.

and I redesign the fin from a semi circle to an aerodynamic shape.
this the idea,
however I'm not sure which angle of the fin can have a better performance
and these are the angle that I figure out,
1.
2.
3.
4.
A guide vane will be added for tested too, but I wonder if there is a guide vane to direct the wind, will the angle of the fin be not so important anymore?
and other idea to enhance are most welcomed =)
thanks
