Structural fatigue testing plays a vital role in assuring the long term integrity of aerospace vehicles and components. However, substantial uncertainty involving large-scale complex structural tests does exist due to their inherent one shot nature. Crack propagation not revealed by a catastrophic failure during a single test can cause structural problems later in production aircraft. The overall objective of this program was to develop a reliable nondestructive testing system for the detection of initiating cracks generated during structural fatigue testing. The goals were to (1) detect cracks as small as 0.050 in. in complex structures and (2) develop a detection system that could be operated by technician-level personnel typically assigned to structural test areas.
