ABSTRACT:
Disclosed is a wind-driven generator apparatus with variable pitch blades. The apparatus includes a yaw damping arrangement for resisting weathervaning rotation of a head assembly of the apparatus about a vertical axis and the apparatus further includes a pitch control mechanism for the blades which maintains the pitch substantially constant during normal operating r.p.m. of the blades but allows the blades to pitch up in an overspeed condition, and a brake mechanism for the generator shaft which includes an adjusting mechanism that compensates for wear in the brake.
