Advances in computational power present an opportunity to further optimize the design of an engineered energetic system. This work presents the application of a proposed optimization scheme which combines the shock-physics hydrocode CTH with the DAKOTA optimization package to automate shaped-charge jet design. The formation of an explosively driven hypervelocity jet is highly dependent on the original shaped charge liner geometry. By parameterizing this geometry, and by developing a characteristic objective function from CTH simulations, a process can be established where the Dakota code iteratively builds an optimal shaped charge. This work attempts to use this methodology to reproduce a reference geometry. This is done by characterizing the liner geometry with two parabolas and post-processing an objective function from the kinetic energy profile of the resulting jet. Multi-dimensional parameter studies, gradient optimizations and genetic algorithms are used to probe the parameter space.
