WINDMILL-ELECTRIC GENERATING PLANT Russian patent published in 2002 - IPC

FIELD: wind- power engineering. SUBSTANCE: windmill-electric generating plant is made in the form of support-mounted power unit incorporating at least one turbine with nozzle assembly mechanically coupled with generator, central shell, annular front shell with at least one turbine inlet passage that constitutes, together with central shell, turbine outlet passage, and also annular external shell forming, together with central shell, outlet diffusion passage; power unit is provided with additional annular shell forming, together with outer surfaces of front and central shells, intermediate converging-diverging passage communicating in intermediate section with outlet passage of turbine; together with inner surface of external shell it forms second intermediate passage communicating, together with first intermediate passage, with outlet diffusion passage. Novelty is that guide fins are installed in inlet passage and/or in converging part of first and/or second intermediate passage to form air flow swirling device. EFFECT: enhanced efficiency of wind flow energy utilization. 9 cl, 3 dwg
