WIND-POWER COMPLEX Russian patent published in 2015 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: invention relates to wind-power complexes and can be used in national economy. A wind-power complex includes electric generators rotated with one or more aeroturbines with a vertical rotation axis. Blades of aeroturbines are attached with inside ends in slots of circles of disks. Disks are uniformly distributed throughout the length of the shaft and rigidly attached to it. Between disks, the shaft surface and ends of the blades there is a space through which all inter-blade cavities are connected. Sharp edges of the blades are plugged with counter-whistling devices. An aeroturbine consists of several turbines installed on each other and attached to each other and to the shaft so that a multisection aeroturbine is formed. Number of blades and height of above located turbines is reduced proportionally to increase of wind velocity with height. The shaft consists of links with flanges on ends and is supported through bearings from frames. Flanges are rigidly attached to each other and to bases of sections. Frames are installed on supports. The shaft is connected through systems of transfer of rotation with electric generators and has a braking system.

EFFECT: invention allows increasing capacity of a wind-power complex and reducing noise level at operation to minimum.
