Combined effects warheads

Abstract

A combined effect warhead device for forming at least one aerostable rod fragment and a plurality of small fragments by explosive formation. The warhead is centered about an axis and contains explosives and liners. A first liner forms an aerostable rod and a second liner forms a plurality of fragments, whereby upon detonation of the warhead, combined explosively formed projectiles are produced including the aerostable rod and the plurality of fragments. In a preferred embodiment, the first liner is unscored and curved, whereas the second liner is scored to facilitate formation of the plurality of fragments. The second liner is almost flat and includes raised portions on its surface to facilitate formation of the plurality of fragments. It is also preferred to include an interface material between the first and the second liner, preferably where the interface material is a combination of explosive material and plastic. The first and second liners may be oriented side by side in the warhead, or, more preferably, in tandem in the warhead. The first liner may be axially above the second liner or the reverse. The warhead is either axisymmetric or non-axisymmetric about its axis.
