METHOD OF OPERATION A GAS TURBINE ENGINE INCLUDING THE SYSTEM OF AIR RECIRCULATION IN THE COMBUSTION CHAMBER SHELL Russian patent published in 2017 - IPC F01D25/26 F01D25/08 F01D21/00 

FIELD: engines and pumps.

SUBSTANCE: method of operating a gas turbine engine, wherein during operation of the gas turbine engine at full load, the valve system is maintained in a closed position to substantially prevent the passage of air through the system piping shell recirculation system. When initiating the transition to the operation at partial load, which is performed in the translation engine cranking state and an off state, the valve system is opened to allow air to pass through the piping system.

EFFECT: invention provides a more uniform temperature distribution in the combustion chamber shell.
