POLYWINDROTOR POWER UNIT Russian patent published in 2013 - IPC F03D3/02 

FIELD: power engineering.

SUBSTANCE: power unit comprises a bearing mast with a rotary unit, a vertical axial turbine, a generator, a tail section. It comprises identical horizontal coaxial arrow-shaped platforms joined to each other by vertical stands at least into one tier. Platforms with their sharpened parts rest against the rotary unit of the mast. In the space between tier platform arms stretching towards opposite sides, but on each of these arms there is an equal number of orthogonal windrotors installed symmetrically to the mast and outside of its contours. Aerodynamic elements of windrotors arranged at different sides of the mast provide for their mutual rotation, at which speed vectors of those specified elements that are most distant from the axis of symmetry of the power unit match with the wind direction. Under the lower platform there are reinforcing stiffening ribs, and tail sections are vertically lifted and rested against the inner edges of the upper platform.

EFFECT: reduced prime cost of power when reducing costs for capital construction with simplicity of operation and maintenance.
