FIELD: mechanical engineering; engines; system delivering cooling air to thermally loaded members of engine. SUBSTANCE: radial through holes in rotor drum outer wall place compressor setting in communication with cooling air distribution space by means of radial channels in inner space of drum formed by cylindrical hollow spokes located between rotor disks. Upper end of each spoke is connected with radial through hole in drum outer wall for displacement, and lower end is secured in through hole made on support cylindrical hood. The latter is installed in rotor drum space in parallel with longitudinal axis of compressor and is cantilever connected with drum. EFFECT: simplified design of cooling air takeoff system and transportation of cooling air with elimination of additional heating of air in drive lines. 3 dwg
