ABSTRACT:
This is a new point-detonating fuze for spin-stabilized munitions. The fuze has three modules housed in a two-piece body, designed to optimize the penetration capability and to adjust the weight of the fuze. The upper body carries the point-detonating module which has a double-initiation feature, designed to function on impact against the target but preventing detonation on impact against rain droplets and against the foliage of wooded areas. The explosion, initiated at the top of the point-detonating module, is propagated by a mild-detonating fuze, first axially inside the shaft of the point-detonating module, then axially through the time-delay module, to reach the detonator in the safing-and-arming module. The point-detonating module acts as a selector designed to provide either a super-quick function or a time-delay function with several time-delay options. The desired choice is made by rotating the moving portion of the time-delay module to one of several pre-indexed positions.
