CIRCUIT ARRANGEMENT FOR AIR COLLECTION, COMPRESSOR STAGE COMPRISING IT, COMPRESSOR COMPRISING THEM AND TURBOJET ENGINEER COMPRISING THE SAME

摘要

In a compressor stage (7) having a movable bladed wheel (10) having moving blades (8) and a stationary bladed wheel (12) having stationary vanes (9), the air sampling circuit arrangement comprises a movable wheel collector (24) for collecting an air flow sucked on the moving blades (8) and a fixed wheel collector (28) for collecting an air flow sucked on the stationary vanes (9), and in that said movable wheel collector (24) is disposed on the periphery of said compressor stage (7) facing said movable wheel (10) and said fixed wheel collector (28) is superimposed on said movable wheel collector ( 24) .Application to a compressor stage (7) of a turbojet engine (1).
