WIND-WHEEL Russian patent published in 2020 - IPC F03D3/06 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Windwheel comprises curvilinear blades forming helical conical helical diffuser channels directed counter clockwise from lower base side. Wind wheel additionally comprises upper end flange. Lower base is made in the form of lower end flange. Surface formed at rotation of wind wheel around vertical axis swept by blades is formed in the form of truncated cone with upper base. Blades are made of sheet material. Each blade is attached simultaneously to upper and lower end flanges of differential hub with central bushing. Attachment point of each blade to the upper flange is offset clockwise relative to the blade attachment to the lower flange. Diameter of cross-section support diameters along windwheel height are set by number sequence of fractions of development.

EFFECT: invention is aimed at improvement of efficiency of wind and heat flows kinetic energy use, simplification of manufacturing and control of geometrical parameters of the main elements of windwheel.
