Abstract : The SPADE system is being developed to detect and isolate degraded Army helicopter power train bearings. It is designed to determine the condition of hanger bearings, 42-degree gearbox bearings, and 90-degree gearbox bearings of the UH-1H, AH-1S, and OH-58A, B, and C aircraft. SPADE is expandable to address added helicopter types and bearing or gearbox types. Current SPADE technology has demonstrated a bearing fault detection rate of better than 90 percent with a false alarm rate less than 10 percent.
