Aerofoils for wind turbine blade

Dear Marshall,
I want to know the aerofoils for best rating of lift and drag for the Re=65,000 ,small wind turbine blade.

Dear Suni,

I’m not actually an expert on airfoils. I am just the guy who makes information about NREL’s airfoils available via the web.

If you have not already done so, please check out our airfoil information ( The section on airfoil families will help you choose one of our sets of airfoils. You can read more about the airfoils in the Airfoils Docs section.
