ABSTRACT:
A point detonating, high explosive incendiary projectile having a safe self estruct fuze that is operative only after setback and spin forces have been imparted to the launched projectile. The fuze includes a rotor housing that is slidable in and spring biased toward the forward portion of a conically shaped nose member. A ball rotor in the rotor housing has a peripheral recess for receiving a tip of the firing pin carried by the nose cap when ball detents in the housing sidewall lock the ball rotor in an unarmed condition prior to projectile launch. A detonator in the periphery of the ball rotor is offset from the recess and is moved to an armed position after rotor freeing of detent unlocking setback and a predetermined amount of spin or centrifugal force. Should the projectile fail to strike a target, upon diminishing spin or centrifugal force, the ball detents re-engage the ball rotor to lock it in armed condition and the rotor housing is biased forwardly toward the firing pin tip for initiating the detonator.
