VANE COMPRESSOR WITH RECYCLING OF THE BOUNDARY LAYER FOR SEPARATION CONTROL OF FLOW

摘要

A guide vane of the axial compressor includes a device for controlling premium layer, comprising: a set of cracks on the back of the blade for selection and feeding of the boundary layer of air; the internal cavity of the blade; a receiver on the end of the blade for the accumulation of air from the internal cavity of the blade; a pipeline connecting the internal cavity of the scapula and a receiver. To prevent boundary layer separation upper wall of the receiver is equipped with a movable element of the reciprocating action for the organization of the periodic suction and blowing of boundary layer air through a set of consecutive slots, which, depending on the position of the movable element to periodically operate the suction, then blowing air.
