摘要

In the compressor the rotor blades (5) have an aerodynamic profile, with their curvature in the direction of rotor motion and their thickness variable such that the distances between the facing surfaces of two adjacent blades (5) when measured perpendicular to the central line (17, Fig. 4) of the outflow channel defined by said surfaces are constant, the stripper (18) being provided on the suction side with an inlet slot (23) of increasing section, and on the compressor delivery side with bevelled edges (25, 26) and flares (27) on the walls of its circumferential channel (19).
