ASYMMETRIC COMPRESSOR AIR EXTRACTION METHOD

ASYMMETRIC COMPRESSOR AIR EXTRACTION METHOD

PROBLEM TO BE SOLVED: To provide a method for mistuning rotating stall aerodynamics by preventing the formation of coherent unsteady loads. SOLUTION: Compressor air is extracted in an asymmetric circumferential pattern (16). The asymmetric extract pattern disrupts the rotating stall cell (10) rotati...

Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for mistuning rotating stall aerodynamics by preventing the formation of coherent unsteady loads. SOLUTION: Compressor air is extracted in an asymmetric circumferential pattern (16). The asymmetric extract pattern disrupts the rotating stall cell (10) rotational pattern, preventing the formation of a coherent aerodynamic excitation. COPYRIGHT: (C)2008,JPO&INPIT
