ABSTRACT:
A vertical axis turbine is provided which comprises a plurality of flexible sail blades attached to a vertically extending, rotatable shaft by upper and lower blade attachment devices, and a power absorbing load device coupled to the rotatable shaft. The flexible sail blades are deployed and stabilized in operation by the centrifugal forces produced in response to rotation of the blades about the vertical axis of the shaft, whereby, in operation, aerodynamic forces acting on the sail blades can be transmitted to shaft without generating bending movements. The sail blades comprise plural elongate flexible sail panels, with flyweights being disposed between and secured to the ends of pairs of the sail panels. In different embodiments, passive flyweights, active flyweights (secondary turbines) and combinations of both types are used.
