3D Hydrocode Analysis of Novel Asymmetrical Warhead Designs
Abstract
In fly over shoot-down munitions, the warhead is mounted perpendicular to the symmetry axis and flight path of the cylindrical carrier. The cylindrical carrier places a geometric constraint on conventional axisymmetric warheads. This constraint limits the warheads diameter, weight, and consequently lethality. In most fly-over shoot down munitions, conventional axisymmetric warheads could not be used, since they would be too small to defeat the required target. The nonaxisymmetric (NAS) warhead concept overcomes these constraints by utilizing the volume along the carrier's axis to put more explosive and liner mass into the warhead, and hence to put more kinetic energy on target. Figure 1 shows the geometric constraints that a cylindrical carrier places on conventional axisymmetric warhead and also how a NAS warhead fully utilizes the volume available within the carrier are both shown.
