WIND TURBINE Russian patent published in 2019 - IPC F03D1/06 

FIELD: power engineering.

SUBSTANCE: invention relates to the wind power engineering. Wind turbine containing a horizontal shaft, multi-blade wind wheel with outer and inner shells and the central zone air flow conical guide fixed thereon. Wind wheel main blades in an amount equal to the outer shell length in meters, are made by their contours cutting out from the disk plane along the radii lines to the inner shell and around its circumference with possibility of bending in the air flow direction, forming the “half-open windows”, at that, on the outer shell additional blades are located in the amount equal to the outer shell length in meters, with stiffening plates, braces and stiffening ribs.

EFFECT: invention is aimed at increase in the wind energy use factor.
