Downwind turbines don't require a yaw drive because the wind manually blows the rotor away from it. Pitch System The pitch system adjusts the angle of the wind turbine's blades with respect to the wind, controlling the rotor speed. By adjusting the angle of a turbine's blades, the pitch system controls how much energy the blades can extract.
