Rotating Stall Recovery
US Patent:
5375412, Dec 27, 1994
Filed:
Apr 26, 1993
Appl. No.:
8/051921
Inventors:

International Classification:

US Classification:
60 3929
Abstract:
In an aircraft gas turbine engine, stator vane deflection and compressor bleed are controlled to alter the compressor airflow vs. compressor pressure relationship map when stall conditions are detected based on compressor speed and compressor temperature, a change that means that less change in pressure required to nudge the compressor from of a stall, accelerating stall recovery. Once the stall has ceased, the stator deflection and bleed are restored to pre-recovery values.
