Solid Rocket Motor Inspection by Acoustical Holography Techniques
Abstract
The feasibility of using acoustical holography as a nondestructive technique for determining small innerbore cracks and debonds in larger solid rocket motors was demonstrated. Cracks as small as one inch long, one-half inch deep, and less than 0.002 inch thick located on the innerbore of a simulated Minuteman third stage motor (18 inch web-thickness) were readily identified. Unbonds of one square inch area between the case and propellant were imaged.
