Missile Warhead Modeling: Computations and Experiments

Abstract

A computational warhead modeling capability has been developed which models the effects of warhead length to diameter ratio, end confinement variation, explosive material and initiation posture, and internal cavity shape and material. These effects are modeled with a time-dependent, two-dimensional, Lagrangian finite - difference computer code, integrally modified to include fragment separation (or fragmentation for continuous warheads) and subsequent explosive gas leakage between fragments. Experimental results of a variety of modeled missile warheads (discrete-fragment warheads) are presented and compared with the computational results. In the experiments the fragment speed and angle distributions with respect to their original position on the warhead are determined through time-sequential, orthogonal flash radiography of the warhead fragment spray in flight, and soft recovery of the fragments after launch.
