DEVELOPMENT OF DEEP DRAWN - ONE PIECE HIGH PERFORMANCE ROCKET MOTOR CASE
Abstract
Progress is reported on the special tooling (dies and punches) for producing the 40-in.-diam monolithic rocket motor cases. Metallographic examinations of strain-hardened samples of 20% Ni, 25 Ni steels, and the all beta Ti alloys indicate the absence of internal microcracks. The Ni steels appeared to be compatible with the coating, soap solutions, and salt bath used for steel, while the all beta Ti alloy tended toward a marginal surface finish when heated in the salt bath. It is proposed to use the tooling from an obsolete 2-in. rocket program for sub-scale deep drawing tests on the 20% Ni and 25% Ni steel and the all beta Ti alloy.
