摘要： Aspects of the disclosure are directed to a sealing system for an engine having an axial centerline, comprising: a stationary carbon segment, and a seal plate that rotates when the engine is operated, where the seal plate includes an end face that is opposed to an interface between the carbon segment and the seal plate, and where the end face includes at least one groove that conveys a liquid cooling fluid.

摘要： A bearing compartment assembly includes a bearing compartment with a bearing and a plenum, a buffer system that supplies pressure to an exterior of the bearing compartment, and a reactive volume vessel connected to the bearing compartment. The reactive volume vessel has a displaceable member that is movable between two positions, one of which adds additional volume to the bearing compartment.

摘要： Aspects of the disclosure are directed to a rotatable shaft, and a plurality of bearings coupled to the rotatable shaft, where the plurality of bearings include a first bearing, a second bearing, and a third bearing, where the first bearing defines an axial first bearing centerline, where the second bearing defines an axial second bearing centerline, where the third bearing defines an axial third bearing centerline, and where the axial second bearing centerline is radially offset from the axial first bearing centerline and the axial third bearing centerline.

摘要： Aspects of the disclosure are directed to a system associated with an engine of an aircraft, the system comprising: a fluid source that is configured to provide a fluid at a first pressure value, a carbon seal, a seal plate that includes at least one lift-off feature that interfaces to the carbon seal, and a pressure boosting mechanism configured to obtain the fluid from the fluid source, increase the pressure of the fluid to a second pressure value, and provide the fluid at the second pressure value to the at least one lift-off feature.
