Abstract: A turbine engine includes a rotor, a stator, and a seal assembly disposed between the rotor and the stator. The seal assembly includes seal segment. The seal segment includes a seal face that is configured to form a fluid bearing with the rotor. A lift channel extends within the seal segment from an opening on the seal face. The turbine engine further includes a spring assembly disposed within the lift channel. The spring assembly including a biasing element and a piston element coupled to the biasing element. The lift channel includes a lift volume portion extending is between the opening and the piston element. The piston element is movable within the lift channel based on a pressure within the fluid bearing to adjust a size of the lift volume portion.

Abstract: A bearing housing for supporting a bearing within a gas turbine engine may generally include a mounting flange and a bearing support ring positioned radially inwardly from the mounting flange. The bearing support ring may be configured to at least partially surround an outer race of the bearing. The bearing housing may also include a support beam spaced axially apart from the mounting flange and the bearing ring, a plurality of inner spring fingers extending axially between the bearing support ring and the support beam and a plurality of outer spring fingers extending axially between the mounting flange and the support beam. At least a portion of each inner spring finger may be spaced apart radially from at least a portion of each outer spring finger. In addition, the inner spring fingers may be circumferentially offset from the outer spring fingers.
