Abstract: A carbon seal assembly for a gas turbine engine is disclosed. The carbon seal assembly includes a first carbon seal. The carbon seal assembly also includes a first carbon seal spring configured to provide force against the first carbon seal in a first axial direction, the first carbon seal spring having an annular shape and circumferentially disposed around a first shaft of the gas turbine engine.

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.
