Advanced controllable solid propulsion thruster development for a lightweight detachable Roll Control System

ABSTRACT: The Air Force is currently evaluating options for MM III life extension under the Ground Based Strategic Deterrence (GBSD) Analysis of Alternatives. Potential life extension solutions include continued use of the existing MM III guidance set in conjunction with modernized solid rocket motor (SRM) stages to replace the existing SRM stages as they age out. These modernized stages will require a Roll Control System (RCS) to be compatible with the existing MM III guidance set. During this SBIR Valley Tech Systems will develop new affordable RCS controllable solid propulsion thruster technology that fills the technical gap for a detachable, affordable, sustainable RCS to be used on these modernized stages. BENEFIT: As a result of our successful MDA SBIR hot gas valve programs, a close working relationship has been formed with our commercialization partners, Aerojet Rocketkdyne, which has yielded a clear recognition that our technology is directly applicable to a future next generation RCS Thruster design. The proposed long duration RCS thruster is one of these enabling gap technologies that leverages previous MDA SBIR hot gas development efforts. The enabling attributes and benefits of the new RCS thruster include: Long duration operation, accurate thrust delivery, packaging flexibility, and down hole ICBM compatibility through the use of solid propellant technology. It is recognized that the RCS thruster technology is a gap filler that specifically enables the RCS design concept. To this end the Air Force has the option to leverage multiple development opportunities to yield a complete long RCS technology set. Our commercialization path the RCS system leverages the Air Force Phase I and Phase II program to specifically develop the RCS thruster technology that will meet the requirements for a follow-on high TRL MM III RCS propulsion system. During the Phase I and Phase II program VTS will work with both the Air Force and Aerojet Rocketdyne to conceptualize the new RCS and derive the requirements for the new thruster technology. For the follow-on acquisition program VTS will transition from the system prime to the RCS thruster provider through a follow-on Phase III SBIR. Aerojet Rocketdyne will lead the follow-on effort to transition the new RCS into production and fielding. These activities include: design, manufacturing planning and facilitization and final design qualification testing and analysis. Aerojet Rocketdyne"s is currently in production for the SM3 Blk1B TDACS.
