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.

A rotor system for horizontal-axis wind turbines, including a rotor hub, a blade having an inner component mounted on said rotor hub to form a first fixed coning angle relative to a reference plane of blade rotation and an outer component extending from said inner component and ending in a blade tip

A rotor system for horizontal-axis wind turbines, including a rotor hub, a blade having an inner component mounted on said rotor hub to form a first fixed coning angle relative to a reference plane of blade rotation and an outer component extending from said inner component and ending in a blade tip, said outer component forming a second fixed coning angle greater than said first coning angle relative to said reference plane of blade rotation.
