ROTARY WIND WHEEL Russian patent published in 2018 - IPC F03D3/06 F03D7/06 

FIELD: wind engines.

SUBSTANCE: invention relates to wind power engineering. Rotary wind wheel contains blades and dampers located between two planes on which the blades are secured with the ability to rotate about the axis. Blades and dampers are directly fixed in sets on the chords of the upper and lower disks used as planes. Each set of the blades and dampers at any point in the circular motion path has blades working in the operating mode and blades in the feathering mode, and the distance between the axes of the adjacent blades of the set and the dimensions of the blades are such that in the operating mode there are no gaps between adjacent blades. Gaps between the edges of the blades that are parallel to the disks and the disks themselves are minimal. Each blade has a rectangular window above which the top side of the flat insert is fixed to it on the blade side, adjacent to the damper in the operating mode, the dimensions of the flat insert and the loading strip ensure the absence of gaps between the flat insert and the blade while an airflow speed is not exceeding the nominal one.

EFFECT: invention is aimed at increasing the rigidity of the wind wheel design.
