Bearing Lubricant Interface Monitoring Using Composite Signature Analysis.

摘要

This report presents the results of the feasibility phase or Phase I of a defense small business advance technology program (DESAT). The ultimate objective of the program is to improve and simplify engine failure prediction. This is to be accomplished by developing a series of objective algorithms which can use the results of standard engine monitoring measurements applicable to the bearing lubricant interface to detect, identify and estimate the remaining life of worn engine components. The Phase I objectives which were performed in the study which is reported here were to: (1) identify the data which is currently available, (2) establish the procedures required to obtain it and (3) to develop demonstration algorithms for a single aircraft engine type which would define the expected improvement in anticipated engine failures and illustrate the use of this approach.
