More Information
Summary:A stall margin modulation (SMM) control system (180) in communication with a gas turbine engine (100) including a compressor (124) is described herein. The SMM control system (180) is configured to determine the stall margin (304) of the compressor (124), operate the gas turbine engine (100) using the determined stall margin (304), assess a health of the compressor (124), and modify the stall margin (304) based on the assessed health of the compressor (124).
