CAROUSEL WINDWHEEL Russian patent published in 2013 - IPC F03D3/06 

FIELD: power engineering.

SUBSTANCE: carousel windwheel comprises L-shaped flaps installed on the vertical axis, blades, thrust frames and dampers. Flaps comprise a radial flap and a flap of identical design, additionally installed perpendicularly to the radial one. Blades are hingedly fixed in flaps as capable of rotation. The axis of rotation of each blade in flaps matches its nearest side edge. Blades in the working mode are pressed to thrust edges fixed in parallel to the plane of each flap via dampers to its design. In the feathered mode the blades take the direction of the air flow without limitations. Frame flaps are pressed between two separating blades that structurally form a single tier. N of such tiers are arranged along the main axis of the wind wheel. The upper separating plane of the n-1 tier is the lower separating plane of the n tier. Flaps of each upper tier are displaced relative to the flaps of the closest lower one by the angle α=2π/ k n, where k - quantity of flaps at one tier (k≥3), n - quantity of tiers (n≥2).

EFFECT: lower efficiency, evenness of rotation, reliability and simplification of wind wheel design.
