ENGINE NOISE MONITORING AS ENGINE HEALTH MANAGEMENT TOOL
First Claim
Patent Images
1. A method for determining the health of an engine comprising:
- sensing a noise spectrum of the engine;
comparing the noise spectrum of the engine to a plurality of standard noise spectra from engines with known defects stored in a database; and
identifying a type and a degree of defect based upon the comparison.

Abstract
A system and method are provided for determining the health of an engine. The method includes a plurality of standard noise spectra collected from engines with known defects. A noise spectrum of the engine being monitored is sensed and compared to the plurality of standard noise spectra from the engines with known defects. From the comparison, a type and a degree of defect is identified based upon the comparison.

8. A method for determining the health of an engine comprising:
-
sensing a noise spectrum of the engine; comparing the noise spectrum of the engine to both a standard noise spectra of a reference engine known to be operating without defects and a plurality of standard noise spectra from engines with known defects; and identifying an existence, a type, and a degree of defect based upon the comparison. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for monitoring the health of an engine comprising:
-
an acoustic sensor configured to acquire a noise spectrum of the engine; and a computer system including a database having a plurality of stored standard noise spectra from engines with known defects, the computer system configured to receive the acquired noise spectrum of the engine from the acoustic sensor and compare the noise spectrum of the engine to the plurality of standard noise spectra from engines with known defects so as to identify a type and a degree of defect based upon the comparison, the computer system generating a match alert along with an applicable recommended action on a display if one or more defects are indentified. - View Dependent Claims (16, 17, 18, 19, 20)
