Abstract: Conduits for guiding the motion of an inner diameter shroud of a low pressure compressor of a gas turbine engine are disclosed. The inner diameter shroud has at least three slots formed in one or more radially inwardly extending flanges. Each of the conduits are configured to assemble with a respective one of the at least three slots. Each conduit comprises a bushing having a first panel, and the first panel is capable of being inserted in a respective one of the slots of the inner diameter shroud. The conduit further comprises a bracket capable of being attached to a bearing support of a fan intermediate case of the gas turbine engine. The bushing is capable of being attached to the bracket. A contact between the first panel and the at least one slot of the inner diameter shroud restricts a circumferential rotation of the inner diameter shroud with respect to a central axis of the gas turbine engine when the first panel is inserted in the at least one slot, but allows a radial motion of the inner diameter shroud with respect to the central axis.
Abstract translation: 公开了用于引导燃气涡轮发动机的低压压缩机的内径护罩的运动的导管。 内径护罩具有形成在一个或多个径向向内延伸的凸缘中的至少三个槽。 每个导管被配置成与至少三个槽中的相应一个组合。 每个导管包括具有第一面板的衬套，并且第一面板能够插入内径护罩的相应的一个槽中。 导管还包括能够附接到燃气涡轮发动机的风扇中间壳体的轴承支撑件的支架。 套管能够连接到支架上。 第一面板和内径护罩的至少一个狭槽之间的接触限制当第一面板插入在至少一个狭槽中时，内径护罩相对于燃气涡轮发动机的中心轴线的周向旋转， 但允许内径护罩相对于中心轴线的径向运动。

Abstract: A seal assembly includes a blade outer air seal, a downstream vane, and a pressure wall, according to various embodiments. The blade outer air seal may include a radially outer surface and the downstream vane may be coupled to the blade outer air seal via a fluid sealing engagement. The pressure wall may be coupled to the blade outer air seal and may define a metering orifice. In various embodiments, the metering orifice of the pressure wall is configured to meter air flow from a first plenum upstream of the pressure wall to a second plenum downstream of the pressure wall. In various embodiments, at least a preponderance of the radially outer surface of the blade outer air seal at least partially defines the first plenum and the fluid sealing engagement at least partially defines the second plenum.

Abstract: A bearing assembly for a gas turbine engine includes, among other things, a bearing housing extending along an axis to define a bearing compartment, a lubricant seal assembly adjacent to the bearing housing to bound the bearing compartment, an air seal assembly defining a vent cavity along the bearing housing, wherein a mixing cavity is defined between the lubricant seal assembly and the air seal assembly, and wherein the bearing housing defines an airflow supply passage, an airflow vent passage and a scupper passage having respective fluid ports at different circumferential positions relative to the axis, the fluid port of the airflow vent passage fluidly coupled to the vent cavity, and the fluid ports of the airflow supply and scupper passages fluidly coupled to the mixing cavity. A method of sealing for a gas turbine engine is also disclosed.
