초록

A method and means are provided for operating a bleed to counter surge in the compressor of a gas turbine. A number of engine condition parameters which are precursors to a change of engine running conditions are monitored to detect changes outside predetermined limits. The method includes deriving a measure of heat soakage effects as an engine condition parameter by monitoring a gas flow value such as compressor outlet pressure, and deriving a further engine condition parameter by evaluating changes of engine power-setting by comparing instantaneous pow...

A method of controlling a compressor bleed valve in a gas turbine engine for a flow of gas from a high pressure region of the compressor to counter compressor surge, said method comprising monitoring one or more properties of the gas flow as an engine condition parameter to obtain a measure of heat soakage effects produced in the compressor by adjustment of relative temperatures between the gas flow and the compressor parts during deceleration of the engine, and the detection of values of said parameter outside a predetermined limit causing said bleed va...
