Abstract

See full text

The wind turbine includes a rotor 6 and a stator 1 mounted coaxially therewith and provided with lower 2 and upper 3 support structures interconnected by vertical guide vanes 4 of the stator, oriented outward. A confuser 22 with blades 23 is mounted on the lower support structure 2, and a diffuser 9 is mounted at least partially above the stator 1. A lower disc 10 of the diffuser is rigidly attached to an upper part 11 of the diffuser that serves as the upper support structure 3 of the stator. Lower 19 and upper 16 half-axles of rotation of the rotor are installed in upper 17 and lower 21 support members, respectively. A rotor body 7 is made in the general approximate form of a hollow truncated cone tapering upward having a curvilinear surface, preferably hyperbolic. Rotor blades 8 have a curvilinear surface, preferably hyperbolic, and are installed on an outer surface of the rotor body 7. Upper 13 and lower 14 impellers with curvilinear blades 15 and 20 are mounted inside the rotor body. A rotor fan 25 is additionally installed inside a cavity 24 of the lower disc 10 of the diffuser 9. The blades of the fan are wrapped around the upper part of the outer surface of the rotor body 7. Spacing of the blades of the upper impeller 13 is chosen to be greater than a blade spacing of the fan 25.
