Safing and arming mechanism

摘要

An out-of-line safing and arming mechanism (10) includes an explosive chain (12) having one link (24) movably mounted on a slider (30) to be removed from the chain in a safing configuration and to be located in the chain in an arming configuration. A head (42) prevents the slider from moving into an arming position and is attached to the slider by an annular connecting system (44) which is stronger in tension and compression than it is in shear. The connecting section is broken by activation of an explosive charge (62) which is located within the connecting section and generates forces (66) tending to shear the connecting section as well as forces (64) tending to move the slider toward an arming position.
