DEVELOPMENT OF HIGH PERFORMANCE ROCKET MOTOR CASE

Abstract

The results of work performed during the contract period June, 1960 to November, 1962 on the development of a high performance rocket motor case using high strength sheet and strip metal are discussed. Metallurgical evaluation of 12 ferrous and nonferrous alloys; selection of 20% nickel maraging steel for application to case; design of a 20 inch diameter by 40 inch long test case; development of a helical welding technique for fabricating cylinders from strip; development of a process to form hemispherical and elliptical heads from low elongation alloys; fabrication and hydrotest of a 20 inch test case; unidirectional ingot solidification of AISI 4340 and 25% nickel maraging steels are summarized.
