WINDWHEEL OF WIND-DRIVEN ELECTRIC GENERATOR Russian patent published in 2014 - IPC F03D1/00 

FIELD: power industry.

SUBSTANCE: invention relates to wind power engineering, and namely to windwheels of wind-driven power plants and wind-driven electric power plants with a horizontal rotation axis, which is mainly intended for operation with electric generators of a segmented type. A windwheel includes a hub connected to the main one-piece blade, to the end of which a bow of a rotor element with teeth and slots is attached by means of bolt connections. The rotor element interacts with the stator element through an air gap. The bow of the rotor element is equipped with a roller that is enveloped with a flexible element, one end of which is fixed on the hub, and the other one is fixed on the tension device that represents a pulley with a worm wheel and a worm. Branches of the flexible element are enclosed with a flexible cover representing a tubular cover forming an additional blade.

EFFECT: simpler and cheaper design at the possibility of changing aerodynamic characteristics of the additional blade by its twisting.
