Abstract
THE FEASIBILITY OF UTILIZING CEPSTRAL ANALYSIS (POWER AND/ORCOMPLEX) IN HELICOPTER GEARBOX BEARING DIAGNOSTICS IS EXAMINED. VIBRATION SIGNATURES ARE EXAMINED FOR DETERMINATION OF WEAR OVER TIME. DATA TO BE PROCESSED ARE FROM TWO DIFFERENT HELICOPTERS, THE TH-1L AND THE H-53. ANALYSIS WILL INCLUDE ALL DATA COLLECTION METHODS AND PROCESSING METHODS. ALL ANALYSIS WILL BE DONE AT ENSCO, INC. OBJECTIVES OF THIS PROGRAM ARE: 1. ANALYSIS OF WEAR AND POTENTIAL FAILURES THROUGH DECONVOLVED DATA VIA CEPSTRAL TECHNIQUES FROM BOTH BEARINGS AND GEARS. 2. DETERMINATION OF THE MOST EFFECTIVE MEANS OF SEPARATING COMPONENT SIGNATURES FROM THE BALANCE OF THE SIGNAL. 3. CONSTRUCTION OF WEAR AND FAILURE CURVES FROM THESE DECONVOLVED DATA.
