Abstract: A bearing system includes bearing unit and a side-jet injector. The bearing unit includes an outer race, a plurality of internal rotating components, and an inner race. The side-jet injector includes an injector for delivering a lubrication source to the plurality of rotating components to withdraw heat generated and lubricate the bearing unit during operation of the bearing system.

Abstract: A bearing assembly may comprise a housing, a slinger disk, and a bearing. The housing may be configured to receive a shaft and having at least one scavenge passage between an outer housing portion and an inner housing portion. The slinger disk may have a plurality of flow guides configured to direct the lubricant flow toward the at least one scavenge channel. The scavenge passage may be configured to provide a lubricant flow through the bearing. Lubricant flow may be provided in a forward direction, through the bearing and opposite a windage direction.

Abstract: An air-inlet particle separator includes an outer wall, an inner wall, and a splitter. The splitter cooperates with the outer wall and the inner wall to separate particles entrained in an inlet flow moving through the air-inlet particle separator to provide a clean flow of air for a compressor section of a gas turbine engine.

Abstract: A bearing system includes bearing unit and a lubrication system. The bearing unit includes an outer race, a plurality of internal rotating components, and an inner race. The lubrication system includes an injector for delivering a stream of lubrication to the plurality of rotating components to withdraw heat generated and lubricate the bearing unit during operation of the bearing system.

Abstract: A flow splitter includes a stepped ring and a flow restriction. The stepped ring includes a first inner wall having a first diameter, a second inner wall having a second diameter less than the first diameter, a radial step that transitions from the first to the second inner wall, and a plurality of apertures circumferentially located along the first inner wall and partially through the radial step. The first flow restriction has at least a portion thereof at a position between the first diameter and the second diameter. Further, the first flow restriction directs a flow of at least one of a gas and a fluid towards the first inner wall, and is configured to split the flow into an exit flow and a secondary flow. The exit flow exits the stepped ring via the plurality of apertures and the secondary flow proceeds downstream directed by the second inner walls.

Abstract: A mounting assembly comprises a mounting member comprising a base having a first surface; a central portion extending from the base and having a second surface spaced from the base; and a shoulder region located between the base and the central portion. The area of the first surface may be different from the area of the second surface. The shoulder region of the mounting member can include a wall extending from at least in close proximity to the second surface of the central portion to the base. In a nonlimiting embodiment of the assembly, the base is cylindrically shaped with a substantially flat first surface, the second surface of the central portion is substantially flat and substantially circular in plan view and further is concentric with the first surface, and the wall extends from the second surface to a location inboard of the periphery of the base.
