METHOD, WORKING MEMBER AND MULTI-ROTOR FOR CONVERSION OF WIND-HYDROPOWER (VERSIONS) Russian patent published in 2010 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: incoming flow in the zone of opposite "a" movement of working member by means of the working member itself is separated along the line perpendicular to rotation axis and supplied to other working members moving in "b" direction following the flow. Working member in zone of "a" movement opposite to the flow is the member which forms additional local flows, and in zone of following "b" movement - the member receiving the flow and which is volumetric and provided with possibility of changing the profile of cross section "a", "b", and functionally formed with different (rear and front) surfaces attached to each other throughout the length of the member. Rear side is flexible and provided with possibility of changing the curvature, front part is rigid and wedge-shaped and provided with possibility of changing the wedge angle. Method has been implemented in three various versions of multi-rotor with the mentioned working members: 1) multi-axial multi-rotor, 2) single-axis multi-rotor with coaxial arrangement of working members, 3) single-axis multi-rotor with planar storeyed arrangement of working members. Design feature of multi-rotors is opposite rotation of working members of adjacent rotors.

EFFECT: more complete and effective use of quick-changing flows as to force and direction.
