SYSTEM SUPPORT STUDIES UNDER PRODUCTION SUPPORT PROGRAM. VOLUME 2. PART 2.
Abstract
Studies were made in support of production programs for Wing VI minuteman second-stage motors. Summaries follow for the nine areas of program effort discussed. (1) Studies were made of various injectant-type TVC systems that could be considered feasible for application with the current second stage and other solid-propellant motors. (2) Toward deriving range increase, investigations were made to increase motor propellant loading and to reduce the weight to inert components. (3) Studies were made of the physical and mechanical properties of LITVC bladder materials; included were Viton A-HV with Dacron, with Nomex HT 2-41, and with Dacron and a nylon barrier. (4) Program studies were directed toward development of leak-proof LITVC joints and replacement of joints through welding. (5) Laboratory performance tests were made of exit cone materials (graphite- and silica-phenolic tapes) and to determine the behavior of these materials and interface bonds when considering effect of material and processing variables. (6) A series of igniter assemblies were tested to determine the adequacy of an igniter initiator having an unbonded, solid polyurethane-foam spacer in place of the bonded, perforated spacer. (7) Ignition properties were characterized for advanced propellants and blends and pelleted pyrotechnics. (8) Evaluations were made of new elastomeric compounds including ethylene propylene terpolymers and butyl acrylics. (9) An intensive study was conducted to resolve discrepancies between inspection data for roll-control valves and position-transducers. (Author)
