The objective of this program is to evaluate experimental rocket motor cases produced under the Army Materials Research Agency Program. This report gives the accomplishments during the fourth quarter. It describes the testing of six Borg-Warner helically wrapped cases incorporated into modified Thiokol M60 rocket motors. Three of the motors were hydrostatically tested and three were statically tested. The results of the tests resulted in the recommendations that the Borg-Warner helically wrapped case be improved by a closer and more constant gap through all fine layers of material. The case concept shows advantages toward the development of a strong lightweight case. Author
