    摘要: The present disclosure is directed to a sump housing (100) for a gas turbine engine (10). The sump housing (100) includes a base portion (118) and a first wall (128) extending outwardly from the base portion (118). The first wall (128) and the base portion (118) at least partially define an inner chamber (134). A second wall (130) is positioned outwardly from the first wall (128) and extends outwardly from the base portion (118). The base portion (118), the first wall (128), and the second wall (130) at least partially define an outer chamber (136) positioned outwardly from the inner chamber (134). A projection (132) extending inwardly from the first wall (128) engages a bearing assembly (52). The base portion (118), the first wall (128), the second wall (130), and the projection (132) are integrally coupled together.

    摘要: A circumferential lubricant scoop (200) for providing lubricant to a bearing assembly. The scoop (200) is disposed circumferentially about and rotates with a rotor shaft (214). The scoop (200) comprises a plurality of lubricant capturing vanes (202) shaped to capture and retain lubricant supplied by a stationary oil jet (122) in a cavity behind a lower lip (212) of the vane (202). This cavity is in fluid communication with channels (208, 216, 218, 224, 226) leading to fluid pathways (108, 116, 118) of an inner race (106) of the bearing assembly. Fluid is moved through the channels (208, 216, 218, 224, 226) and fluid pathways (108, 116, 118) due to the rotational force imparted by the rotating rotor shaft (214).

    摘要: A heat exchanger array (54) includes a first row (60) of heat exchangers (60A, 60B), a second row (62) of heat exchangers (62A-62C), and side curtains (68). The first row heat exchangers (60A, 60B) are spaced apart to define first gaps. The second row heat exchangers (62A-62C) are spaced apart to define second gaps and are positioned downstream of and staggered from the first row heat exchangers (60A, 60B) such that the second row heat exchangers (62A-62C) are aligned with the first gaps and the first row heat exchangers (60A-60B) are aligned with the second gaps. Each side curtain (68) is in close proximity to a first row heat exchanger (60A, 60B) and a second row heat exchanger (62A-62C). The side curtains (68) define a neck region (N) upstream of and aligned with each first row heat exchanger (60A, 60B) and each second row heat exchanger (62A-62C). Each neck region (N) has a neck area that is less than a frontal area of the heat exchanger with which it is aligned.

    摘要: A lubrication circuit for a gas turbine engine includes a bearing compartment, an air inlet connected to the bearing compartment, a lubricant inlet, and a lubricant outlet. The air inlet fluidly connects the bearing compartment to an environment external to the compartment. The lubricant inlet and outlet are connected to the bearing compartment. A scavenge valve is operatively connected between the lubricant outlet and a scavenge pump that is responsive to bearing compartment pressure for controlling pres sure drop across the air inlet.
