Abstract
An ultra-miniature, electro-mechanical, MEMS type safe and arming (S&A) device for medium- or large-artillery rounds, including, three sequenced S&A interlocks: a setback slider which provides a 1interlock with respect to an arming slider which moves due to the round's spin; a stop and release mechanism that holds the arming slider until a release command signal is initiated by the fuze circuit, triggering a spot charge which generates an expanding gas wave that flexes the latch arm from contact with the safety catch, unlocking the 2interlock, thereby freeing the arming slider to continue its motion into an arming position, unlocking the 3interlock, and aligning the parts of the firetrain within the device, such that upon signal from the fuze circuit to an output charge, the device will ignite the acceptor charge within the round.
