COMPRESSEUR A REINJECTION D'AIR

摘要

The compressor has a casing for housing compression stages provided with radial-flow impellers (RM1) that are movable and driven in rotation, where one of the stages precedes an inlet synchronizing ring (RDE). The synchronizing ring includes adjustable fixed blades (18) with an air re-injection circuit and pivots (20) traversing the casing. The re-injection circuit includes injection holes (22) traversing certain fixed blades of the ring and internally opening near the pivots, at an inlet of the compressor.
