DESIGN OPTIMISATION FOR SHAPED CHARGE JET PERFORMANCE

Abstract

The performance of a shaped charge warhead is a direct consequence of specific design features such as the liner geometry. By dynamically modifying the geometry of the shaped charge design through a newly developed hydrocode optimisation and parameter suite, we are able to rapidly assess and improve upon a SC baseline concept. The hydrocode IMPETUS AFEA is used to model the formation of a SC, using Jet Kinetic Energy, Mass, Velocity and Particulation as the performance metrics. By using the experimental shaped charge BRL, a Jet KE increase of 6.7% was achieved. Using a baseline design and a newly devised performance metric taking into account both Jet KE and particulation we were able to increase the performance by 9%.
