<p><P>PROBLEM TO BE SOLVED: To provide a method for mistuning rotating stall aerodynamics by preventing the formation of coherent unsteady loads. <P>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. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
