Rotor

The rotor is the airfoil structure that spins in the wind, using lift to transform wind energy into mechanical (rotational) energy. The Windspire® rotor employs an efficient giromill design with a large sweep area for maximum energy capture. It is unique in its tall, narrow, minimalistic profile that makes it aesthetically appealing and appropriate for a wide variety of settings. The rotor is constructed with multiple airfoil segments to reduce strain and to transfer wind-induced stresses to the high strength center shaft. The rotor was designed with the aid of extensive aerodynamic computer modeling to maximize power production, done by the world’s premier expert in Darrieus rotors. The mechanical system was further refined using advanced rotordynamic modeling of vibration modes, performed by another leading expert in rotordynamics.
