摘要
A vertical axis wind turbine having a single vertical structure 4 drives a generator 14 within the structure via a structure encircling ring and planet gear arrangement. A blade hub 1 mounted automatic blade pitch control mechanism allows aerodynamic blade pitch alteration relative to the airstream. Blade 2 motion is damped and controlled by a non-Newtonian fluid within the hub 1 that controls the blade pitching motion from excessive and violent movement as the blade 2 is rotating around the vertical axis. The fluid passes via a narrow channel between alternately expanding and contracting chambers in the hub. Speed control and stopping is controlled by an actuating mechanism comprising a structure encircling annular ring 31 driven by hydraulic or electric motor driven actuators 21 that move the ring vertically to engage wheels and a linkage connected to flaps 11 to raise the flaps and apply air braking to the wind turbine.
