| description | A system for cooling the axial compressor (2) of a turbomachine and for controlling radial clearances in the compressor comprises means (10) for taking cooling air from the primary air flow (P) through the compressor, means (11) for modulating the cooling air flow (R) which is taken, means (14) for cooling the cooling air flow (R), means (17) for supplying the cooled cooling air to a collector (18) situated under the final stator vane stage (6a) of the compressor, and means (19) for ejecting the cooled air from the collector (18) towards the disc (3a) carrying the final stage of rotor blades of the compressor. A portion (R1) of the ejected cooled air (R) flows through the compressor drum (1), from downstream to upstream, through spaces (20) formed between the roots of the rotor blades (5a, 5b) and the bottoms of the cells of the discs in which the roots are mounted, and another portion (R2) is used to cool the cone (4) of the drum (1). |
