Failure Modes And Prognostic Techniques For H-60 Tail Rotor Drive System Bearings

The failure modes and diagnostic/prognostic signatures for the oil cooler and hanger bearings used in the tail rotor drive system of the H-60 series of helicopters are being researched. The overall goal is to develop a prognosis system to track and predict bearing degradation and to integrate those technologies with the open architecture IMD-HUMS. This paper summarizes the challenges and advancements that have been experienced while improving the diagnostic capabilities for the bearings.
