Aging and Surveillance Program MINUTEMAN II/III Stage II Program Progress

Abstract

This semiannual report provides results of tests conducted in support of the aging and surveillance program for the Minuteman II and III Stage II motors. The primary objectives of the program are to provide assurance that (1) the reliability of the presently deployed motor will not degrade within a projected replacement time of 17 years; and (2) the service life of the remanufactured motor will be equal to or greater than that of the presently deployed motor population. This volume also summarizes results of work conducted on two of three plug motors. Testing incorporates several sample types from each motor (bulk, excise, and through-the-case plugs) to evaluate differences in properties with respect to location or sample type. Propellant-Liner-Insulation problems, thrust vector control system components, and rocket igniters are reported upon. Keywords: Solid propellant rocket engines; Aging(materials); Rocket propellant grains; Hardening; Cracks; Second stage engines; and Ignition delay.
