Compressor operating method for aero engine gas turbine, involves controlling air valve arrangement based on detected operating mode, and cooling air flow by coolant valve arrangement through injecting arrangement

摘要

The method involves detecting an operating mode of a compressor (1). An air valve arrangement (11) is controlled based on the detected operating mode. Air flow is cooled by a coolant valve arrangement (12) through an injecting arrangement (4). Temperature of the air flow is controlled by the coolant valve arrangement. Independent claims are also included for the following: (1) a compressor (2) an aero engine gas turbine.
