F02C 9/00

Abstract:

A system and method for monitoring and diagnosis of engine health are provided. In one aspect, a system receives continuous operating data (COD) associated with an asset. The COD includes parameter values for one or more parameters over a collection time period. The system generates synthetic snapshot data based at least in part on the COD. The synthetic snapshot data includes one or more synthetic snapshots each containing the parameter values for the one or more parameters for a given timepoint within the collection time period. The system also receives snapshot data associated with the asset. The snapshot data includes one or more snapshots each containing parameter values for the one or more parameters for a given timepoint. The system generates an output indicating a health status of the asset or one or more components thereof based at least in part on the snapshot data and the synthetic snapshot data.

F16C 19/52

Abstract:

A bearing assembly monitoring system includes a bearing assembly supporting rotation of a rotating member. The bearing assembly includes a fixed portion and rotatable portion. A piezoelectric element is mounted to the fixed portion and generates an electric signal in response to a vibration of the fixed portion. A first transceiver is electrically coupled to the piezoelectric element to receive the electrical signal generated by the piezoelectric element and generate a signal indicative of the vibration of the fixed portion. A gas turbine engine bearing monitoring system and a method are also disclosed.
