FIELD: engines and pumps.
SUBSTANCE: modified Darrieus turbine consists of generator with vertical rotary shaft. Said shaft is equipped with, at least, three wing-shaped blades bent from rotational axis. Turbine additionally comprises the same number of smaller-height blades uniformly shifted in plan and concaved to the same rotational axis. Smaller-height blades are jointed to the shaft at approach section via radial pins to thrust against horizontal rings by their edges. Said rings are fitted at said convex blades.
EFFECT: higher output, durability and stiffness.
