Direct Drive Electromechanical Actuators for Jet Blast Deflectors Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-103 Topic Title: Direct Drive Electromechanical Actuators for Jet Blast Deflectors Proposal No.: N052-103-0215 Firm: Infoscitex Corporation 303 Bear Hill Road Waltham, Massachusetts 02451-1016 Contact: James Goldie Phone: (781) 890-1338 Web Site: www.infoscitex.com Abstract: A direct-drive electric linear actuator for raising and lowering the jet blast deflector (JBD) is proposed that achieves the specific force necessary to be a form-fit-function replacement for the existing JBD hydraulic actuators. Moreover, we propose a design that is suited to modularity, allowing the actuator to be readily scaled to meet the requirements for other Navy shipboard applications. Successful replacement of all of these hydraulic actuators with electric actuators would allow the elimination of the entire catapult hydraulic system. A building block actuator and the associated power and control electronics will be designed during Phase I. In addition to the theoretical design work aimed at meeting fundamental performance requirements, attention will be paid to manufacturability, cost, reliability, maintainability, and operational features such as braking and cleanliness. During Phase II, construction and test of a single building block will be followed by prototypes with increasing capability until full-scale performance is achieved. The prototypes will demonstrate performance (force, stroke and speed) as well as maintainability and reliability of the actuator system. The Phase II design will be reworked during Phase III to produce a full-scale system JBD actuator to be installed and tested under realistic environmental and operational scenarios aboard a carrier. Benefits: Direct drive electrically-powered actuators with force densities comparable with hydraulics will bring the benefits of electric actuation to a myriad of current and future applications where currently only hydraulics is suitable: automobiles & trucks, robots, construction & earth moving equipment, aircraft, ships, and submarines.
