WIND TURBINE PLANT Russian patent published in 2017 - IPC F03D3/04 F03D3/06 

FIELD: machine engineering.

SUBSTANCE: wind turbine plant has a rotor mounted in the housing made in the form of a centrifugal impeller with blades, and a wind trap comprising vertically oriented blades bent towards the wind flow and displaced relative to each other with successive overlap with formation of vertical air duct therebetween. The rotor is mounted on the wind trap and configured in communication with it. The rotor housing has outlet branch pipes, one end of each branch pipe communicates with inner part of the rotor housing, and the free end is directed into the air duct of the wind trap. The blades of the wind trap are provided with stiffening ribs arranged at an angle to the horizontal plane with inclination towards the wind flow on the inner and outer sides of the blades. The rotor blades are fixed on the centrifugal impeller from the inner surface of the housing and directed along the chords of the rotor housing.

EFFECT: increased performance and efficiency of the plant for any duration, speed and direction of the wind.
