Abstract:
In a compressor stage including a movable bladed wheel having movable blades and a fixed bladed wheel having fixed blades, an air tapping circuit arrangement includes a movable wheel manifold designed to collect an air flow aspirated from the movable blades and a fixed wheel manifold designed to collect an air flow aspirated from the fixed blades. The movable wheel manifold is placed on the periphery of the compressor stage facing the movable wheel and the fixed wheel manifold is superposed on the movable wheel manifold.
