BELT-BLADE DEVICE FOR PRODUCING FLOW Russian patent published in 2017 - IPC B63H1/34 

FIELD: transportation.

SUBSTANCE: belt-blade device for producing a flow comprises of blades which move along the trajectory of a moving close-loop belt placed over the rotating wheels. The blade position relative to the direction of movement is set by a blade control system. Each blade consists of a blade shaft which is fixedly secured to the blade ends, of close-loop belts on the outer surface of which bearings are mounted, in which the rotating shafts of the blades, driving and driven wheels, which have close-loop belts over them, a control system setting the position of the blades relative to the direction of their movement and kinematically connected to the shafts of the blades, a protective outer casing, a frame for fixing units of the belt-blade device for producing a flow.

EFFECT: obtaining a directed flow of gas or liquid with a controlled difference in the linear velocities of the blade points.
