Exhaust system having a flow rotation element and method for operation of an exhaust system
An exhaust system in an engine is provided. The exhaust system includes an exhaust passage including an outlet, in fluidic communication with at least one combustion chamber in the engine, and integrated into a cylinder head in the engine and a flow rotation element including at least one vane, the flow rotation element positioned in the outlet of the exhaust passage swirling exhaust airflow exiting the exhaust passage..

Providing oxidation to a gas turbine engine
A gas turbine engine includes a compressor for compressing air from an environment; a combustor for receiving the compressed air from the compressor, mixing the compressed air with fuel, and combusting the fuel; a turbine coupled with the compressor for receiving exhaust gas from the combustion and powering the compressor; and an injector coupled with a source of oxidizer for injecting the oxidizer into the combustor. A method for operating a gas turbine engine includes compressing air from an environment; receiving the compressed air at a combustor; mixing the compressed air with fuel; injecting oxidizer into the combustor in addition to the air from the environment; combusting the fuel with the compressed air and the oxidizer; receiving exhaust gas from the combusted fuel; and powering the compression of the air from the environment using the exhaust gas..

Air regulation for film cooling and emission control of combustion gas structure
A gas turbine engine compressed air flow control arrangement, including: a combustion gas structure having an acceleration geometry (20) configured to receive combustion gas (18) from a can combustor and accelerate the combustion gas (18) to a speed appropriate for delivery onto a first row of turbine blades, the combustion gas structure defining a straight combustion flow path; a film cooling hole (58) disposed through the combustion gas structure at a location within or downstream of the acceleration geometry (20); a sleeve (64) surrounding at least a portion of the combustion gas structure comprising the film cooling hole and defining a volume (62) between the combustion gas structure and the sleeve (64); and an adjustable flow control system configured to adjust a flow volume between the plenum (44) and the volume (62).. .
