ABSTRACT:
A safe and arm device having a bellows motor-driven rotor bearing a detonr. When the device is in the SAFE condition the detonator is shrouded by an airpot piston extending from one end of a spring secured within the airpot cylinder in the housing. The airpot piston compresses the spring in response to weapon acceleration until the piston fully resides in the airpot cylinder in the device housing. The rotor is thus free to be rotated overriding a detent maintaining the SAFE condition by the action of the bellows motor which is electrically activated. The rotor turns until it reaches the "ARMED" position where the detonator therein is positioned directly in line with weapon's warhead explosive trigger charge in the housing. The rotor is rotationally secured relative to the housing in the "ARMED" position by the action of another detent.
