Abstract
A secondary self-destruct fuze that functions in the event the primary fuze mode fails to function, and that meets the design requirements for a low cost, highly producible no-spin/low velocity operating environment. The fuze includes an improved slide assembly comprised of an aerodynamic safety release (ASR), a safety pin, a secondary firing pin fitted with a spring, a secondary detonator which is placed in alignment with the secondary firing pin, a slide, an omni directional weight release that operates at various impact angles, and a weight release support. In use, the fuze is fitted to a munition or grenade. As the grenade is dispensed from its carrier, the oscillation of a grenade stabilizer causes an arming screw to back out from the fuze slide, allowing the slide assembly to move to an in-line position relative to the center of the fuze. Concurrently, the aerodynamic safety release is lifted in the upward direction under the force of the airstream, releasing the safety pin. This releases the weight release support, which slides out of the fuze. Upon impact with ground, the omni directional weight release drops in a corresponding cavity in the slide, freeing the secondary fir…
