Abstract:

In order to achieve a fragmentation device having a highly effective coupling between the fragments and high explosive used therewith, as well as a very lethal incendiary effect when combined with a pyrophoric ingredient, enabling this device to bring about increased devastation upon supplies or equipment of an enemy, we provide in accordance with this invention a novel layered arrangement in which one or more layers of pyrophoric material such as a zirconium alloy are interposed with one or more well-defined layers of high explosive and fragments, thus making possible very high fragment velocities, a high density, uniform pattern of fragments, and most importantly, a wide dispersion of pyrophoric particles with the fragments that serve to cause immediate conflagration of any oils, fuels or other combustibles that are in the vicinity of the target, or which have been released by the action of the fragments thereupon.
