High-g testing through controlled deceleration has proven to be a key to the successful development of electronics that must survive gun launch. A magnetic method of deceleration has been widely implemented in a related commercial application (amusement park rides), because magnetic braking has the advantages of simplicity, low-maintenance costs, high-repetition rates, and predictable performance. An advanced version of this technology can meet the higher deceleration needs of the Army Research Laboratory s component testing program. This technology also improves the fidelity of the tests by allowing a deceleration profile to be programmed. Sierra Lobo, Inc. (Sierra Lobo) proposes to design, fabricate, and test a prototype High-G Magnetic Capture System (HGMCS) in Phase I. The simplicity of the configuration, the amenability of electromechanical systems in general to accurate performance prediction, and the availability of components for the system make it possible to fabricate and begin testing a full-scale prototype. During testing, emphasis will be placed on developing operating procedures and making design refinements that minimize both operating costs and the time that personnel must spend preparing for high-g simulations. Testing will continue during Phase II. If necessary, additional prototypes will be fabricated incorporating the lessons learned during testing.
