WIND SET Russian patent published in 2006 - IPC F03D3/06 

FIELD: wind power engineering.

SUBSTANCE: invention relates to converters of energy of air flows into rotation of wind set. To provide serviceability under action of wind and upward air currents in any combination and increase power output, wind set containing vertical carrying pipe, axle of connection with drive of energy carrier, unit of movable connection, upper and lower belts secured on carrying pipe between which sectors are arranged bent to arc, is furnished with pipe-air conduit, lower belt adjoins with clearance pipe-air conduit. Proposed set is made in form of wheel with spokes and is furnished with inclined blades in number equal to number of sectors. Sectors are installed with tilting along screw line relative to carrying pipe, and axle of connection with drive of energy carrier is found on upper parts of carrying pipe. Diameter of wheel of lower belt - d is found from equation d=D-(0.5-0.9)H where D is diameter of upper belt, H is belt-to-belt distance, diameter of hole of pipe-air conduit is equal to outer diameters of lower belt, blades of lower belt are secured on spokes movably, for displacement relative to horizontal plane from 10° to 80°, and outer end faces of sectors projecting beyond circumferences of belts are made with radius r=(0.4-0.5)D.

EFFECT: improved serviceability of wind set.
