  • Patent number: 3978796
    Abstract: The present invention relates to fragment projection-blast devices capable f focusing fragmentation and destructive blast effects. In particular, the invention takes the form of a warhead characterized by interior, multipoint initiation of detonation which increases metal velocity and enhances blast properties, a truncated cone charge and metal liner arrangement which controls metal projection direction and blast propagation, and end plates which partially confine gaseous products and enhance initial blast properties. According to the invention, an explosive composition is shaped by the projectile walls and by metal truncated cone arrangements on the warhead. Detonators located in the interior of the explosive compositon and opposite the apices of the truncated cones ignite simultaneously, causing directed fragmentation.
