INJECTION AIR COOLING THE ROTOR The gas turbine engines and cooling method SUCH ROTOR

摘要

1. A gas turbine engine comprising: a compressor section, wherein compressed air drawn into the engine, a combustion section where fuel is mixed with at least a portion of the compressed air from the compressor section and burned to produce hot combustion gases, a turbine section where the hot gases of combustion from the section expanding combustion to extract energy from them, wherein at least part of the extracted energy is used for rotating the turbine rotor during a first engine operating condition, comprising at full load operation, the camera otorrhea in communication with a cooling structure within the turbine section and at least one rotor cooling pipe which injects air main path extracted from the motor, in the rotor chamber during the first mode of engine operation; isistemu air injection, comprising: at least one outlet opening through which air auxiliary path is extracted from the engine only during the second mode of engine operation comprising operation with a load less than full, said at least one conduit of the rotor cooling is used to an auxiliary air path injection, the extracted at least one outlet in the rotor chamber during the second mode of engine operation, a piping system, which provides for fluid the second medium between the at least one outlet and at least one rotor cooling pipe; injection system for extracting auxiliary air path of the engine through at least one outlet opening and to transmit the extracted auxiliary air path through the system
