Abstract
A safe and arm device for aligning elements of an energy transfer mechanism of an ammunition fuze includes an inertial mass, an energy transfer mechanism interrupt barrier component and an energy-loadable spring, all movably mounted in a bore of a housing of the device. The inertial mass is movable for producing an arming force in response to application of a predetermined acceleration force to the housing. The bi-stable barrier component is movable from a pre-armed stable safe position to a post-armed stable sterilized position in response to the applying of the arming force to the component upon being released from its stable safe position. In moving to its stable sterilized position, the barrier component moves through an armed position in which the elements of the energy transfer mechanism are aligned in firing relation with one another during a momentary period of time. The energy-loadable spring interconnects the inertial mass and barrier component for storing the arming force produced by movement of the inertial mass and applying the arming force to the barrier component.
