How does windspeed affect my rotor design?
A. Your rotor is optimised for a particular tip speed ratio. As long the ratio is maintained, your same physical rotor will still be optimum at any windspeed. The matching to your generator however will vary with windspeed and so you may want to adjust diameter and TSR and number of blades to best suit your generator at a particular windspeed which you expect to be the norm. Also windspeed affects the reynolds numbers which then affect lift and drag which might then prompt you to revise the rotor design (particularly at low reynolds numbers below 100000).
