System arrangement for governing gas turbine engines, especially gas turbine aero-engines

摘要

A system arrangement for the control of acceleration processes in gas turbine engines, especially gas turbine aero-engines. The system arrangement includes means for measuring the actual ratio of pressures at the outlet and inlet of the compressor operating in front of the combustion chamber and providing signal values indicative of the measured pressure ratio, means for comparing the measured pressure ratio signal values with a set of predetermined pressure ratio signal values for an operating range of the engine which predetermined signal values are set below the value corresponding to compressor surge, and means for controlling the metered fuel value for the engine in response to the actual measured signal value exceeding the predetermined pressure ratio signal value.
