    Abstract: An apparatus has: a first member; a shaft rotatable relative to the first member about an axis; and a seal system. The seal system has: a seal carried by the first member and having a seal face; a seal carrier; a seat carried by the shaft and having a seat face in sliding sealing engagement with the seal face; and one or more springs biasing the seal carrier relative to the first member so as to bias the seal face against the seat face. The seal carrier has: an axially-extending wall having an inner diameter (ID) surface; and a radially-extending wall having a first surface. The seal carrier axially-extending wall ID surface has a radially inwardly open groove having a first sidewall and a second sidewall and a base. A wave-form split ring contacts the first sidewall and biases the seal into engagement with the radial wall first surface.

    Abstract: An assembly for a compartment of a gas turbine engine that includes a housing, a gear, and a baffle disposed about the gear. The baffle includes an upstream portion and a downstream portion. The upstream portion includes an upstream inner wall and an upstream outer wall separated from the gear. The upstream inner wall is positioned between the upstream outer wall and the gear. An upstream flow channel is formed between the upstream inner wall and the upstream outer wall. The downstream portion of the baffle includes a downstream inner wall and a downstream outer wall separated from the gear. The downstream inner wall is positioned between the downstream outer wall and the gear. A downstream flow channel is formed between the downstream outer wall and the downstream inner wall.

    Abstract: A fan assembly of a gas turbine engine includes a fan rotor including a fan rotor hub, and a plurality of fan blades extending radially outwardly from the fan rotor hub, and a fan case including an inner case portion and an outer case portion surrounding the plurality of fan blades. A plurality of struts extend between the inner case portion and the outer case portion. A bearing assembly is configured to support the fan rotor at the inner case portion. The bearing assembly includes a bearing inner race secured to the fan rotor, a bearing outer race secured to the inner case portion, and a plurality of bearing elements located radially between the bearing inner race and the bearing outer race.
