Abstract

A fuzing system for use in operating tandem demolition warheads to sequentially activate a propellant on the rear of a follow through charge, detonate a forward shaped charge and detonate the follow through charge after a brief delay. An interface charge is located proximate to blasting caps. A first fuze responsive to the interface charge is configured to ignite the propellant and to arm the first arming assembly. A second fuze responsive to the interface charge is configured to arm the second arming assembly. A first arming assembly containing a first firing pin is located proximate to the follow through charge. A delay fuze is interposed between the first primary charge and the follow through charge. A second arming assembly containing a second firing pin is located proximate to the forward-shaped charge. In the armed state, a primary explosives are interposed between the firing pins and the follow through charge and forward shaped charge. The ignited propellant accelerates the follow through charge into the second firing pin, detonating the forward-shaped charge and forming a hole in the structure to be demolished. The shock wave from the detonation of the foward-shaped charge …
