Abstract: A bearing system is provided for a gas turbine engine. This bearing system includes a spring defined about an axis of rotation. The spring has a multiple of beams which extend between a flange and a damper attachment. A damper defined about the axis of rotation and mounted to the spring to at least partially axially overlap the multiple of beams.

Abstract: A centering spring assembly of a turbomachine according to an exemplary aspect of the present disclosure includes, among other things, a damper beam, a bearing support, and a spanner nut. At least a portion of the damper beam axially overlaps at least a portion of the spanner nut relative to a rotational axis of the turbomachine.

Abstract: A seal assembly includes a first component and a second component of a gas turbine engine. The first component has a threaded portion. The second component interfaces with the threaded portion and together the threaded portion and the second component form a seal that restricts fluid flow between a first cavity and a second cavity of the gas turbine engine.

Abstract: In accordance with an embodiment, a gas turbine engine is provided having a bearing chamber leak detection system. The gas turbine engine includes a rotatable shaft, a bearing assembly supporting the rotatable shaft, and a plurality of bearing chamber seals surrounding the rotatable shaft creating an annular bearing chamber enclosing the bearing assembly. One or more walls substantially surrounding the bearing chamber create a plenum between the walls and the bearing chamber, and a pressurized air inlet to the plenum is provided. The pressurized air inlet includes an airflow sensor configured and positioned to sense a flow of pressurized air into the plenum, such that airflow at the sensor is indicative of airflow from the plenum into the bearing chamber via one or more of the plurality of bearing chamber seals.

Abstract: A sealing system for use with at least one rotating shaft has a tandem seal arrangement contacting a surface of the at least one rotating shaft. The tandem seal arrangement includes at least one pair of segmented ring assemblies. Each of the segmented ring assemblies contacts the surface of the at least one shaft.
