摘要： Embodiments of a gas turbine engine cooling system (100) for deployment within a gas turbine engine (18) are provided, as are embodiment of a method for producing the same. In one embodiment, the gas turbine engine cooling system (100) includes an impeller (36) having a hub (52), a plurality of hub bleed air passages (102), and a central bleed air conduit (104). Each hub bleed air passage (102) has an inlet (106) and an outlet (108) formed in outer and inner circumferential surfaces of the hub (52), respectively. The central bleed air conduit (104) is fluidly coupled to the outlets (108) of the plurality of hub bleed air passages (102) and is configured to conduct bleed air discharged by the plurality of hub bleed air passages (102) to a section of the gas turbine engine (18) downstream of the impeller (36) to provide cooling air thereto.

摘要： Embodiments of a turbomachine (10), such as a gas turbine engine, are provided. In one embodiment, the turbomachine includes an impeller (24), a main intake plenum (20) in fluid communication with the inlet of the impeller, and an impeller shroud recirculation system (12). The impeller shroud recirculation system includes an impeller shroud (42) extending around at least a portion of the impeller and having a shroud port (44) therein. A shroud port cover (46) circumscribes at least a portion of the shroud port and cooperates therewith to at least partially define an impeller recirculation flow path (50, 56). The impeller recirculation flow path has an outlet (66) positioned to discharge airflow into the main intake plenum at a location radially outboard of the shroud port when pressurized air flows from the impeller, through the shroud port, and into the impeller recirculation flow path during operation of the turbomachine.
