ABSTRACT:
A shock tolerant fuze includes a detector for determining when fuze timing should be initiated, a movable safe and arm assembly containing a time delay circuit and a firing aperture. The firing train detonator is preferably also mounted on the movable armature. When the fuze is armed, the time delay circuit is coupled to the detector and to the detonator, and the aperture provides a pathway between the output of the detonator and the remainder of explosive firing train of the weapon. Electrical energy storage is provided on the armature for powering the time delay circuit and the detonator in the event that primary power thereto is interrupted by impact. By including the time delay circuit and energy storage on the movable armature, a very shock tolerant fuze is obtained.
