Electro-Mechanical Timer Development

Abstract

This report documents the design and development of a fail-safe electro-mechanical timer (EMT) compatible with the requirements of MIL-STD-1316 and suitable for missile and bomb fuze applications. The EMT provides the accuracy and versatility of an electronic timer while assuring the safety of a mechanically out-of-line, interrupted firing train. This innovative design provides delayed mechanical arming without requiring stored energy devices. The EMT employs pulsed miniature solenoids which convert electrical power into mechanical energy for advancing a ratchet wheel and gear train, thus accomplishing the mechanical arming stroke of a fuze rotor.
