DEVELOPMENT OF DEEP DRAWN,ONE-PIECE HIGH PERFORMANCE ROCKET MOTOR CASE.

摘要

The general objective of this contract is to utilize the hot cup-cold deep draw fabrication method to develop improved monolithic rocket motor cases for 40'' (and over) diameter solid propellant rockets. The specifice goals are: 1. The development of reliable motor cases with hoop stress limits substantially in excess of 200, 000PSI steel equivalent. 2. A capability of fabrication with reasonable ease on an industrial scale. 3. A producibility proven by reliability tests at final full scale. 4. The objective is to be accomplished utilizing the Pershing 2nd stage motor case configuration.
