Abstract: A seal assembly is disclosed. A seal assembly may comprise a seal carrier, a compliant structure comprising a first end and a second end, wherein the first end is coupled to the seal carrier, and/or a support structure coupled to the second end. The seal carrier may be integral with the compliant structure.

Abstract: An assembly includes a bearing having an annular shape, a bearing support radially outward from the bearing, a squeeze film damper having a first end adjacent the bearing and a second end adjacent the bearing support with the second end forming a squeeze film damping surface, and a first spring between the bearing and the bearing support with the first spring configured to resist a movement of the bearing to center a shaft radially inward from the bearing.

Abstract: An assembly includes a centering spring having an annular flange, an annular body, and a plurality of resilient beams extending from the flange to the body. The annular flange defines a passage that extends at least radially inward with respect to a centerline circumscribed by the flange from a radially outer surface of the flange to a radially inner surface of the flange. The annular body is spaced from the flange along the centerline, a radially outer surface of the body forming a first annular cavity relative to an adjacent surface configured to be a first fluid damper. A deflection of the body relative to the flange is restrained by a restoring force produced by the plurality of resilient beams and the first fluid damper. A method includes providing the aforementioned assembly and passing a damping fluid through the passage of the flange.
