Advanced Electromechanical Actuation System for Jet Blast Deflectors (JBDs) Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-103 Topic Title: Advanced Electromechanical Actuation System for Jet Blast Deflectors (JBDs) Proposal No.: N052-103-0474 Firm: Dynamic Controls, Inc. 7060 Cliffwood Pl. Dayton, Ohio 45424-2929 Contact: Gavin Jenney Phone: (937) 254-2529 Abstract: This proposal describes an electrical actuator which uses a hydrostatic transmission to convert the rotary motion of the motor to linear output motion. The hydrostatic transmission provides the gear reduction required by the actuator. By using a variable displacement pump in the the transmission, the gear ratio can automatically be varied to match the loading conditions. The variable gear ratio allows minimizing the motor size and power for the jet blast deflector actuation system. Benefits: The ability of an electrically powered actuator to continously vary the gear ratio between the motor and output will provide a smaller, more efficient actuator for applications with varying loads. This reduces actuator size and thermal problems. Commercial applications are any electrical actuation system required to move large varying loads, such as on mobile equipment, manufacturing equipment, log splitters, etc. Return
