Abstract : The integrity of solid propellant rocket motors is essential to their reliability. Consequently, for the motors presently used in large rockets, complete raidiographic inspection is normally required. Future motors planned for advanced space vehicles will, however, be much larger and satisfactory radiographic coverage with existing high-energy x-ray machines and film speeds will become impossible. Sensitive scintillation detectors and associated electronic systems in place of the film offer a possible solution to the problem. Extrapolation to motors as large as 20 feet in diameter has also shown the method to be a promising means of accomplishing this difficult testing task. (Author-PL).
