Not Available The subject program seeks to design, develop, and fabricate a miniature actuation and control system suitable for the control of pinnate position on a tactical solid rocket motor (SRM). Next-generation missile systems must be versatile, agile, and smart. IN SRM's this smart capability can be accomplished by varying pinle position during motor operation thereby changing the motor throat area causing thrust to vary by controlling the motor pressure. Two elements to these overall pintle design are required. The first is a miniature mechanical pintle that resides within the SRM chamber during motor burn that varies the nozzle throat area on electrical command. Second, is a miniature electronic control system to provide closed loop control of pintle position based on the real-time feedback of motor pressure. Phase I, will design both the pintle actuation and electronic control system based on PRI's demonstrated test experience with hot gas valves (HGV). Design emphasis will be placed on achieving miniature size, and low weight. Aminiature actuation system with brassboard electronics will be tested in a representative SRM to verify performance. Minimum response time, minimum power, and durability are certain based on the demonstrated mechanical design approach to be followed. Phase II will encompass miniaturized fabrication and testing of an operational pintle actuation and control system in F/W SRM using thermal battery power. BENEFITS: The commercial applications f
