A WIND TURBINE AND ROTOR ASSEMBLY

摘要

A wind turbine (1) including: a generator (6); a rotor (8) coupled to the generator; and a plurality of weights (9,10) distributed about the axis of rotation of the rotor to balance centripetal forces generated by the rotor in use. The weights (9,10) are provided opposite the rotor and disposed about 120 degrees apart from each other and the rotor in the plane of rotation of the rotor. The rotor (8) is tiltable with respect to a drive coupling (7) to the generator (6). Control means (3) controls the load applied to the generator to balance the centripetal forces and aerodynamic lift and drag generated by the rotor (8) in use to achieve a desired degree of rotor coning.
