METHOD FOR AIR CIRCULATION IN A TURBINE COMPRESSOR, COMPRESSOR DESIGN USING THIS METHOD, COMPRESSOR LEVEL AND COMPRESSOR CONTAINING SUCH CONSTRUCTION, AND AIRCRAFT ENGINE,

摘要

The method involves sucking air, present in an inner jet, in cavities (42), for two compression stages of a compressor, where each stage includes a fixed wheel and a movable wheel (14). The air sucked in the cavities is driven inside fixed vanes (22) of the fixed wheel. The air in the fixed vanes of the fixed wheel is bleeded, and the air is then driven out of the compressor. Independent claims are also included for the following: (A) lay out of compressor for implementing air circulation method (B) an aircraft engine including a compressor.
