WIND-DRIVEN POWER GENERATOR Russian patent published in 2011 - IPC F03D3/06 F03D3/04 

FIELD: power industry.

SUBSTANCE: wind-driven power generator includes rotor with vertical rotation axis, which is arranged inside fixed case of wind guide plates 1. Rotor is formed with blades 4 attached to carrying cylinder 3 so that slot diffuser 5 is formed between them and carrying cylinder 3. Each of blades 4 is equipped on front side of its plane with the main vortexes which are made with protrusions 7 of Δ- or I-shape, which are longitudinal and made in the form of blades 4 perpendicular to the plane. On rear side of each blade 4, on its vertical edge which is the closest to carrying cylinder 3, there is additional vortex in the form of longitudinal thickening 8 having Δ-shape in its cross section. Side edge of longitudinal thickenings 8, which faces carrying cylinder 3, is convex. Blades 4 can be both solid and hollow, including filled with polymer foam filler. Available protrusions 7 improve formation of vortexes on front side of blades 4, and available longitudinal thickenings 8 increase the volume of vortex area after rear side of blades 4 and accelerate their airflow passing through slot diffuser 5.

EFFECT: improving efficiency coefficient of wind-driven power generator.
