Question

Wind power output equation based on angle of attack

Answer 1

Answer:

However, the definition of the angle of attack is based on the wind tunnel ..... Aerodynamic characteristics of wind turbine blade airfoils.

Answer 2

Thus, 5° pitch angle is optimum for a wind turbine when the operating velocity is 7 m/s for optimum power generation. ... When velocity is reduced to 7 m/s, a very small angle of attack is obtained. Hence the maximum FL/FD ratio is obtained for 15.1 m/s and a low FL/FD ratio is obtained for 25.1 m/s and 7 m/s.
