Rotor system for horizontal axis wind turbines
Patent
·
OSTI ID:6498498
A rotor system for horizontal-axis wind turbines is provided having compound coning and a sweep angle to improve the rotor system's yaw responsiveness and stability and to reduce vibration and stress. To further improve wind turbine performance and rotor durability blades with the load-bearing function and airfoil function separated are disclosed and are particularly useful in rotor systems having compound coning or compound coning and sweepback. The load-bearing function and support function of the rotor hub are separated to improve rotor system durability and to provide a rotor hub for use with a pitch change mechanism for altering the pitch of rotor system blades.
