FIELD: engines and pumps.

SUBSTANCE: wind engine mounted on a base containing vertical blades mounted around the blades between the top and the bottom plates wind-guiding walls, one ends of which are located at the circumference, describing the blades, and the other ends are withdrawn to the periphery. The opposite ends of adjacent walls are arranged along a straight line running through the axis of the wind engine. The blades are further provided with an upper cover and a lower cover with annular beads corresponding to the annular grooves formed in the upper and lower plates and formed a labyrinth seal with them, the upper plate covered with a convex casing, the lower plate forming the upper base of the truncated pyramid which side planes are rigidly connected to the base. The planes of adjacent blades are conjugated with cylindrical surfaces, and each annular bead is provided with at least three wheels equipped with couplings mechanically connected to electric generators.

EFFECT: increase the service life of the design and increase the coefficient of use of the wind flow.
