WIND PLANT (VERSIONS) Russian patent published in 2008 - IPC F03D3/04 

FIELD: wind-power engineering.

SUBSTANCE: wind plant consists of a suction duct, guide vanes and a wind wheel which is made in the form of rotation body and installed above the suction duct, and a vortex generator. The latter represents an axially symmetric hollow-type cone and wings which are made in the form of two opposite rotated semi-cylinders with diameter D, the centres of which are located on the cone base line intersecting longitudinal vertical centreline plane, and diameters are connected with the cone base radius R₁ in the following way: D<R₁<10D. In another version the vortex generator consists of a cone and wings which form Archimedes spirals and represent mating circles the radii of which R₂ and R₃ are in the ratio R₃/R₂=1.618 corresponding to Fibonacci number. In the other version the vortex generator consists of wings made of two mating arcs of circles with radius R₂ and R₃=2R₂.

EFFECT: invention allows improving wind use coefficient and reliability, and decreasing manufacturing and operating costs.
