ACCELERATION SENSING MODULE FOR MUNITION SAFETY SYSTEMS

THE PROPOSED PROGRAM INCLUDES THE ANALYSES, INVESTIGATIONS, AND EVALUATIONS NECESSARY TO RECOMMEND A DESIGN OF A MINIATURE, LOW-COST ACCELERATION SENSING AND INTEGRATING MODULE FOR USE IN MISSILE SAFETY AND ARMING SYSTEMS. THE DESIGN GOALS INCLUDE A SIZE NOT TO EXCEED 0.03 IN(2) AND A COST OF $15 EACH IN QUANTITIES OF 100. A BASIC SYSTEM ARCHITECTURE OF AN ACCELERATION TRANSDUCER AND A SIGNAL PROCESSOR IS PROPOSED. SEVERAL TRANSDUCER TECHNOLOGIES ARE IDENTIFIED FOR CONSIDERATION. FACTORY PROGRAMMABLE GAIN, CALIBRATION, AND THRESHOLD SETTINGS ALLOW A SMALL FAMILY OF SENSORS TO COVER A WIDE RANGE OF MUNITION LAUNCH ENVIRONMENTS. PROTOTYPE TRANSDUCERS AND BREADBOARD ELECTRONICS WILL BE BUILT AND EVALUATED DURING PHASE I. PHASE II WILL INCLUDE FULLY INTEGRATED ELECTRONICS AND FABRICATION AND TESTING OF A DESIGN QUALIFICATION LOT.
