Research Topics


Based on our proven track record, Sonoma Design Group LLC (SDG) will design a miniaturized pintle actuator that will be low cost and highly producible in typical tactical missile quantities. The control system will allow rocket motor thrust to be controlled during flight and is comprised-of an actuator, a movable pintle, a pressure sensor and the guidance computer. The actuator includes the pintle actuator, with motor and reduction system, and the electronic popover driver. During Phase I SDG will develop an actuator unit cost goal in 1 it with production tactical missile cost requirements. Careful consideration for high reliability and system safety will be made throughout the design. SDG has formed a team of capable companies to carry the effort from design to production. This team includes SDG, Aerojet/Sacramento, and Versatron. SAG will lead the actuator miniaturi7atior! and cost reduction effort. During Phase I and II, SDG will perform the initial system and actuator design and fabrication, Aero jet and Versatron will supply proven components and technology. Upon completion of Phase II, our team will carry the pintle actuator system into production. SDG will work with Aerojet and Versatron during both SBIR Phases to assure a smooth transition into production. BENEFITS: This system will fill a general need for tactical missile systems for substantially improving the performance, range, and inner and outer boundaries for many existing tactical missiles. Potential exists for an upgrade to existing missile systems to allow increased performance without redevelopment programs. The general manufacturing and cost improvements which are expected during this SBIR will be applicable to a broad spectrum of industrial products such as machine taxis, aircraft systems and possibly automotive systems.
