Abstract: A gas turbine engine includes an engine static structure. A rotating structure is configured to rotate relative to the engine static structure. The rotating structure has a target area with first and second directions. The first direction is greater than the second direction. A lubrication system includes a nozzle having a non-circular exit aimed at the target area. The exit provides a width and a height. The width is greater than the height. The width is oriented in the first direction.

Abstract: One embodiment of the seal housing for a face seal described herein include a base with a seal element support and a shroud both extending from the base in a common direction. The seal element support and the base define a space for receiving a seal element. The shroud includes a tip having a head portion that tapers toward a neck portion that is reduced in size relative to the head portion. The tip is secured to a stem of the shroud through a set of circumferentially distributed countersunk holes.

Abstract: An oil accumulator assembly may comprise a scavenge tube including an aperture defined by a break in the scavenge tube and/or an annular cylindrical structure concentrically situated about the scavenge tube. The aperture may be configured to receive oil flowing through the scavenge tube, and the annular cylindrical structure may be configured to accumulate oil flowing through the aperture. The oil accumulator assembly may further comprise a drainage outlet disposed in the annular cylindrical structure. Oil accumulated within the annular cylindrical structure may drain through the drainage outlet in response to an engine being shut down. The oil accumulated within the annular cylindrical structure may fill a portion of the scavenge tube situated within an engine fan case to prevent coking within the scavenge tube.
Abstract translation: 储油器组件可以包括清扫管，其包括由清扫管中的断口限定的孔和/或同心地位于扫气管周围的环形圆柱形结构。 孔可以构造成接收流过扫气管的油，并且环形圆柱形结构可以被构造成积聚流过孔的油。 储油组件还可包括设置在环形圆柱形结构中的排水口。 积累在环形圆柱形结构内的油可能会响应于发动机关闭而排出排水口。 积聚在环形圆柱形结构中的油可以填充位于发动机风扇壳内的清扫管的一部分，以防止清扫管内的焦化。

Abstract: A gas turbine engine may have a fan section that includes a variable pitch mechanism for changing the pitch of fan blades. The gas turbine engine may include a fan hub that is rotatable about an engine central longitudinal axis of the gas turbine engine and a blade receiver that is for holding a fan blade and that is rotatably coupled to the fan hub and may be rotatable about a radial axis of the gas turbine engine. The gas turbine engine may include a spring element disposed between the fan hub and the blade receiver to bias the blade receiver radially outward and an annular retaining ring may be disposed around the radial axis and between the fan hub and the blade receiver to limit radially outward movement of the blade receiver to prevent the blade receiver from decoupling and disengaging from the fan hub.

Abstract: A ring seal assembly includes a first ring seal that is symmetrical with respect to a radially extending plane. A second ring seal is separated axially from the first ring seal by a spring. The second ring seal includes a first inner circumferential surface. An interference feature extends radially inward from the first inner circumferential surface to a second inner circumferential surface.
