Small Portable Analyzer Diagnostic Equipment (SPADE) Program -- Diagnostic Software Validation.

摘要

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. (Author).
