Method for air circulation in a turbomachine compressor, compressor arrangement using this method, compression stage and compressor incorporating such a arrangement, and aircraft engine equipped with such a compressor

摘要

For a compression stage of a compressor comprising several compression stages ( 28 ) with a rotor ( 14 ) and a stator ( 26 ), an outer casing ( 8 ) and an inner casing ( 4 ) delimiting a flowpath ( 10 ) with an <> ( 34 ) and an <> ( 36 ), the method comprises an air suction operation in which air sucked in from the inner flowpath is sent into a vane of said stator, and a bleed operation in which air is bled in said vane and is sent outside the compressor. The compressor arrangement for use of the method comprises suction means ( 42, 44 ) and bleed means ( 48, 50 ).
