FIELD: power industry.
SUBSTANCE: wind engine includes blades of concave shape, aerodynamic surfaces and a vertical shaft. Blades are installed on cross beams of A shape. Each cross beam is installed with its top by means of a hinge on the vertical shaft fixed with its upper end so that it can interact with a working machine. Aerodynamic surfaces are fixed on blades with an inclination providing occurrence of a lifting force acting on one of the blades in upward direction and on the opposite one in downward direction.
EFFECT: invention allows improving transfer efficiency of wind flow energy, simplifies the wind engine structure and improves its reliability.
