The Selection and Demonstration of Advanced Nondestructive Testing Techniques for on-Site Missile Inspection. Volume II. Appendices.
Abstract
The report describes a program planned around the problem of on-site non-destructive testing (NDT) of solid rocket motors. It was designed to select, evaluate, and demonstrate NDT capabilities, beginning with comprehensive surveys of industry and the world's literature (from 1960 to mid-1972). Only two techniques showed promise: Ultrasonic holography and gamma radiography. In the ensuing developments ASPC evaluated two ultrasonic systems. The first, modified ultrasonic holography, was developed from known principals of holography and ultrasound transmission through materials. The theoretical resolution of this system ranges between 0.4 in. and 1 in. at a depth of 18 in. into the propellant. The second system, acoustic profilography, uses the principal of diffraction to measure the shortest path across a secant of the motor. (Modified author abstract)
