FIELD: mechanical engineering; axial-flow compressors.
SUBSTANCE: invention relates to disk of axial-flow compressor of turbomachine containing system of centripetal air takeoff for cooling of turning arranged in passage part of compressor. Said air takeoff system contains channels 9 made out of the limits of disk working section parallel to said section in thickened part forming projections out of the limits of working section on surface 7 of said disk. In proposed disk takeoff channels 9 are open in axial direction over radial extent.
EFFECT: simplified design of disk of axial-flow compressor.
