摘要： A cooling air system for use in a gas turbine fuel injector (32) includes a microchannel fuel-air heat exchanger (38). The fuel-air heat exchanger (38) allows heat transfer between a flow of cooling air used to cool components of the engine and a flow of fuel used to drive the engine and includes a leak management system (40).

摘要： A gas turbine engine includes devices, systems, and methods for providing bleed air from the compressor impeller to the turbine for cooling and/or other use. The bleed air may include compressor cooling air that is routed through the diffuser and external to an outer bypass duct and/or internally to a forward wheel cavity of the turbine.
