A program to investigate and evaluate techniques for forming the internal cavities in large solid propellant rocket motors was divided into three phases. Under Phase I, candidate processing techniques were evaluated and recommendations made for the technique which should be further developed in subsequent phases. At the conclusion of Phase I, the Air Force redirected effort on the program toward development of the castable combustible core concept as applied to the WS-120A system. During Phases II and III, the most promising combustible material was tailored and its suitability was demonstrated by static testing in 5-inch-diameter rocket motors. (Author)
