A method of operating a gas turbine engine includes a system RECIRCULATION SHELL combustion chambers

摘要

1. A method of operating a gas turbine engine having a longitudinal axis defining an axial direction of the motor, the method comprising: during a first mode engine operation: compressing air in the compressor section, mixing at least a portion of the compressed air with fuel and burning the mixture in a section combustion to form hot gaseous combustion products, expanding the hot combustion gases in the turbine section to extract energy from the combustion gases, wherein at least a portion Highlighted energy used for rotation of the turbine rotor; ipodderzhanie valve in the closed position to substantially prevent the passage of air through the system piping recirculation system shell, wherein the shell recirculation system is connected with a part of the motor housing located around sections combustion, and comprises: at least one release member formed in said motor housing portion; at least one inlet element formed in said motor housing part; piping system which provides message in fluid communication between said at least one discharge element and said at least one inlet member, an air blower adapted to the air outlet from the interior volume of said housing portion through said at least one discharge element for moving allotted air to said at least one inlet element; iklapannuyu system, which selectively permits and prevents the passage of air
