Prediction of Equipment Failures by Acoustical Signature Analysis - Phase 1

Abstract

Magnetic tapes of vibration from 12 cylinder, AV-1790-7 engines before and after repair were analyzed. A computer program (OP-SEEKER) determined from the vibration which engines were faulty (needing repair) and which were not. Although only 6 different engines were examined (a larger sample size would have been a better test of OP-SEEKER), 100% success was obtained.
