Abstract
A self destructing impact fuse including a cylindrical firing pin having a hollow centrifugal chamber for holding a number of spheres and a number of radial openings on its surface for exposing portions of the spheres when the chamber is spun. At one end of the chamber is a spring for exerting compression force along the longitudinal axis of the chamber and at the other end is a self-destructing (SD) firing pin for striking the detonator. A centrifugal lock having a pivot offset from the longitudinal axis holds the chamber in place by mating with a groove on the surface of the centrifugal chamber. The cylindrical firing pin is seated concentrically within a frame and disposed over an escapement assembly featuring the detonator. The detonator is rotated into alignment with the SD firing pin after the projectile, incorporating the fuse, travels the minimum tactical distance. The frame is further coupled with a base, which features a point detonation (PD) firing pin for striking the detonator.
