RADIALLY EXPANDING FRAGMENTATION WARHEAD STUDY
Abstract
This report summarizes experimental and analytical accomplishments toward the objective of explosively projecting multilayers of performed fragments into uniform radial disc patterns and at controlled velocities. The radial velocity of each fragment is to be proportional to its distance from the longitudinal axis of the warhead, and a predictable expansion pattern is to be between 500 feet per second and 2000 feet per second on the diameter. The program approach emphasizes experimental investigations of various warhead design concepts that could possibly result in radial pattern distributions with controlled fragment velocities. Data are presented on four basic designs and variations thereof, which have been experimentally evaluated through warhead arena testing. Of the designs tested, an explosive layered concept provides the most promise for achieving program objectives. This design is comprised of a cylindrical package of alternating layers of performed fragments and sheet explosive in either involute wrapping or concentric ring configurations. The analytical portion of this study is oriented toward determining means of describing the physical behavior of multilayer fragments when subjected to an explosion in a radial direction.
