HELICOPTER HEALTH MONITORING

This article describes the various techniques used on helicopters for engine and gearbox surveillance, considers main and tail rotor balancing and tracking, and the very latest method of vibration signature analysis and monitoring. Chronologically, the first health monitoring techniques were filter examination, magnetic chip detectors and, later, Spectrometric Oil Analysis Programme or SOAP. These practices were pioneered in the Armed Services by forming Early Failure Detection Centers (EFDCs). Improved filter examination now uses powerful stereoscopes and the use of scanning electron microscopes is planned.
