WIND POWER-GENERATING DEVICE Russian patent published in 2007 - IPC F03D1/04 

FIELD: power engineering.

SUBSTANCE: proposed wind power-generating device includes construction base, wind velocity amplifier formed by two cones, external and internal ones, arranged opposite to one another by their vertices, and turbine with blades twisted in direction opposite to direction of its rotation, and electric generator connected by common shaft with turbine. External cone and electric generator are secured on construction base, internal cone of wind velocity amplified is secured by its base on common shaft and is provided with blades over surface to form turbine at output of which nozzle assembly is made installed in space between cover of external cone and base of internal cone of wind velocity amplifier. Moreover, one side of base opposite to internal cone blades are fastened being twisted in one direction with turbine blades and forming, together with base of internal cone and cover of external cone, a centripetal wheel whose output channel is pointed to side of electric generator and encloses common shaft.

EFFECT: increased efficiency of device, improved stability at low velocities of wind, provision of forced cooling of generator.
