摘要:
An internal heating arrangement for a centrifugal impeller (20) for a gas turbine engine is provided having at least one heating passage (62, 54, 56, 31, 58, 60) extending through the rotor for directing hot bleed air.
摘要:
A heat exchange system (10) for use in fluid operated equipment to provide air and working fluid heat exchanges to cool the working fluid in airstreams on a stream side of a wall (11). An actuator (40) is mounted to be substantially located on a side of the wall (11) opposite the stream side thereof having a positionable motion effector. A heat exchanger core (20) having a plurality of passageway structures (21) therein to enable providing the working fluid to, and removal therefrom. The heat exchanger core (20) is mounted on the motion effector so as to be extendable and retractable thereby through the opening (13) for selected distances into that region to be occupied by the airstreams.

摘要:
Système de refroidissement d'une cavité aval de rouet de compresseur centrifuge dans une turbomachine, ce compresseur (10) étant raccordé à un diffuseur (12) comportant un flasque annulaire aval, une tôle annulaire (70) étant montée coaxialement autour du flasque du diffuseur et s'étendant sensiblement sur toute la dimension axiale du flasque pour définir un passage annulaire (72) de ventilation alimenté en air qui est plus frais que l'air (61) sortant du compresseur centrifuge.
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.
