Abstract:

Ultrasound is arguably the most effective nondestructive testing method for the inspection of subsurface faults. However, hand scanning of parts is subject to inspector error and fatigue, and automated point-by-point is extremely time consuming. We are reporting on the results of the use of a novel ultrasound camera for the rapid inspection of composite rocket motor cases in both production and in-service settings. This camera technology can be used for a variety of materials of different sizes and geometries. Using this system, subsurface delaminations, voids, cracks and other faults can be seen with high resolution and quantified immediately. This technique results in scans that can be done several times faster than conventional point-by-point or hand scanning.
