    Abstract: Systems and methods are disclosed for sealing a high pressure fluid cavity from a low pressure fluid cavity in a rotating machine such as a gas turbine engine. The cavities are at least partially disposed between a rotatable shaft and a sump housing radially displaced from the rotatable shaft. A seal assembly comprises an air riding carbon seal ring and a circumferential ceramic runner. The carbon seal ring is sealingly engaged with the sump housing and has a radially inward facing seal surface. The circumferential ceramic runner is carried by the shaft and has a radially outward facing seal surface extending axially along the shaft. The radially inward facing seal surface of the air riding carbon seal ring sealingly engages the radially outward facing seal surface of the ceramic runner during rotation of the rotatable shaft at a predetermined range of rotational speeds.

    Abstract: A system includes an air chamber and an oil capture cavity. The air chamber includes an inlet to receive pressurized air from a gas turbine engine. The oil capture cavity is positioned between the air chamber and an oil sump supplying lubricating oil to the gas turbine engine. The oil capture cavity includes an auxiliary vent formed in a base of the oil capture cavity. A seal may separate the oil capture cavity from fluid communication with the oil sump. A nozzle provides fluid communication between the oil capture cavity and the air chamber. The nozzle is configured and positioned to direct a stream of the pressurized air into the oil capture cavity against an opposite wall of the oil capture cavity to create a quiescent zone at the base of the oil capture cavity. The quiescent zone includes the auxiliary vent.

    Abstract: A clutch assembly may comprise a plurality of clutch discs and a housing configured to receive the plurality of clutch discs. The housing may include an outer wall and an inner wall defining a channel therebetween. The outer wall may have an inlet port and an outlet port in fluid connection with the channel. The channel may be configured to pass a first heat transfer medium between the inlet port and outlet port. The housing may include a plurality of surface features extending inwards from the inner wall and toward the plurality of clutch discs. The plurality of surface features is configured to transfer heat from second heat transfer medium to the housing, thereby transferring heat away from the plurality of clutch discs. The channel may be configured to transfer heat from the housing to the first heat transfer medium, thereby transferring heat away from the housing.

    Abstract translation: 离合器组件可以包括多个离合器盘和构造成容纳多个离合器盘的壳体。 壳体可以包括限定其间的通道的外壁和内壁。 外壁可以具有与通道流体连接的入口端口和出口端口。 通道可以被配置成在入口和出口之间通过第一传热介质。 壳体可以包括从内壁向内延伸并且朝向多个离合器盘延伸的多个表面特征。 多个表面特征被配置为将热量从第二传热介质传递到壳体，从而将热量从多个离合器盘传递离开。 通道可以被配置为将热量从壳体传递到第一传热介质，从而将热量从壳体传送出去。
