Transmission Condition Assessment.
Abstract
This program was conducted to provide the correlation and analysis of vibration signatures, component condition and oilborne debris from 38 CH-47C rotor transmissions tested under a spectrum of load conditions. The transmission tested included new, postoverhaul, and preoverhaul scheduled and unscheduled removals. The analysis of data shows the relative diagnostic accuracies of transmission condition assessment by analysis of particulate debris from filters and by spectral analysis of demodulated high-frequency vibration.
