✦ Synopsis

As a technique, computed tomography (CT) has may applications. This Paper describes how the valuable nondestructive evaluation (NDE) tool was used to inspect welds on critical ground support equipment for the space shuttle at the Kennedy Space Center, as other NDE techniques proved unsuccessful. Some welded-end hydraulic accumulators were thought to contain fatigue cracks, which lmight lead to high-velocity or high-volume leakage of hydraulic fluids. CT. was successfully used to identify three levels of fatigue defects.
