SYSTEM AND METHOD FOR MONITORING HEALTH OF STATOR VANES
First Claim
1. A system, comprising:
- a plurality of sensing devices configured to generate acoustic emission (AE) signals that are representative of acoustic emission waves propogating through a plurality of stator vanes;
a processing subsystem that is in an operational communication with the plurality of sensing devices, and the processing subsystem is configured to;
generate a dynamic threshold based upon an initial threshold and the AE signals;
determine whether a plurality of signals of interest exist in the AE signals based upon the dynamic threshold;
extract the plurality of signals of interest from the AE signals based upon the dynamic threshold;
determine one or more features corresponding to the plurality of signals of interest; and
analyze the one or more features to monitor and validate the health of the plurality of stator vanes.

Abstract
A system including a plurality of sensing devices configured to generate acoustic emission (AE) signals that are representative of acoustic emission waves propagating through a plurality of stator vanes is presented. The system further includes a processing subsystem that is in an operational communication with the plurality of sensing devices, and the processing subsystem is configured to generate a dynamic threshold based upon an initial threshold and the AE signals, determine whether a plurality of signals of interest exist in the AE signals based upon the dynamic threshold, extract the plurality of signals of interest from the AE signals based upon the dynamic threshold, determine one or more features corresponding to the plurality of signals of interest, and analyze the one or more features to monitor and validate the health of the plurality of stator vanes.
