CH-46 & OH-58 Transmission Stress Wave Analysis

Abstract

This report documents the results of testing on two types of helicopter transmissions. The analysis of high frequency stress wave data indicates various types of problems that were detected with gears and bearings in both CH-46 and OH-58 gear boxes. The types of discrepancies detected include shaft misalignment as a function of flight loads; planet gear/bearing assembly damage, sun gear damage, wear-in phenomena, and the presence of particulate debris in the lubrication system.
