FIELD: power industry.
SUBSTANCE: in wind-driven unit containing rotor that includes blades connected to each other by means of traverses and the rotation axis of which is located across flow direction the blades are made in the form of a spatial spiral of segment profile; at that, inner edge of segment profile adjoins the surface of imagined rotation body, and its straight-line part coincides with continuation of radius of rotation body the geometrical axis of which is rotation axis of the rotor connected in elastic manner to foundation with possibility of being inclined to different sides.
EFFECT: simpler design and higher efficiency of wind-driven unit.
