Improving accuracy for both direct- and indirect fire weapons is a major challenge to the ballistician during gun and projectile development. The ability to control the interior and exterior ballistic processes to minimize adverse dynamic perturbations to the projectile during the launch represents a major step toward designing in accuracy. Numerical simulation allows the study of the in-bore motion of the project and projectile-gun system interaction. Recent advances in this methodology include the validation of three-dimensional, transient modeling, which includes highly anisotropic composite materials. The method is applied to the study of the gun barrel effects impacting both mean jump and dispersion for both composite and isotropic sabots.
