DIGITAL SAFE & ARM DEVICE FOR GUIDED MISSILE

MAJOR ADVANCES IN MICROMECHANICAL COMPONENTS IN RECENT YEARS HAVE MADE POSSIBLE NEW DESIGN APPROACHES FOR A SAFE AND ARM DEVICE. DEVELOPMENTS IN CUSTOM INTERGRATED CIRCUITS NOW ALLOWS THE DESIGN OF A "SUBSYSTEM ON A CHIP". RECENT ADVANCES HAVE ALSO BEEN MADE IN MICROMECHANICAL DEVICES, INCLUDING THE DEVELOPMENT OF A SILICON ACCELEROMETER. THE OFFEROR PROPOSES TO INVESTIGATE THE FEASIBILITY OF AN ELECTRONIC G-SWITCH USING AN INTEGRATED SILICON SENSOR AND AMPLIFIER AND A CUSTOM INTEGRATED CIRCUIT. A DESIGN CONCEPT FOR THE INTEGRATED SENSOR IS PROPOSED WHICH MINIMIZES SENSITIVITIES TO MANUFACTURING TOLERANCES AND ENVIRONMENTAL CONDITIONS. THE OFFEROR PROPOSES TO INVESTIGATE THE FEASIBILITY OF AN ELECTRONIC SEQUENCER TO PERFORM PREARM MESSAGE VALIDATION, SEQUENCING,AND TIMING FUNCTIONS. A SEQUENCER DESIGN CONCEPT IS PROPOSED WHICH TAKES ADVANTAGE OF DEVELOPMENTS IN MICROCOMPUTERS AND CUSTOM INTEGRATED CIRCUITS.
