FIELD: engines and pumps.
SUBSTANCE: gas turbine plant with double-flow engine includes low pressure compressor, as well as external circuit channel and high pressure compressor provided with air bypass gate valves from intermediate step to external circuit channel, which are all installed downstream. On external housing of external circuit channel above bypass gate valves there installed are air bypass valves connected at the inlet to external circuit channel, and at the outlet - to atmosphere, with possibility of their advanced or simultaneous connection with air bypass gate valves. Ratio of flow area of bypass valves to flow area of bypass gate valves is 0.8…2. Air bypass from intermediate stage of high pressure compressor to external circuit channel excludes surging of low pressure compressor.
EFFECT: improving reliability of gas turbine plant.
