摘要	Wind-driven electric generator apparatus has a generator head supported on a tower for free-yaw movement and for free-pitch movement within predetermined limits. The generator head has a downwind rotor with a pair of elongated blades mounted on a hub that is rigidly attached to a rotor shaft driving an electric generator. The blades are flexible and have a coning angle therebetween that varies with wind velocity. The generator head is capable of aligning itself with the wind direction azimuthally and elevationally. A yaw brake prevents an excessive yaw rate. In most preferred embodiment, pitch movement and yaw movement beyond small angular ranges are regulated, and an electrohydraulic yaw drive system corrects gross azimuthal misalignment with respect to the wind direction.
