Abstract : Improvements have been made in a suite of computer simulations designed to model the launching of saboted, fin-stabilized projectiles from smooth bore guns. These modifications include modeling of the projectile release from the gun tube, subsequent sabot petal shape alteration because of the release of the gun tube constraints on the launch package and inclusion of more realistic initial conditions for the sabot discard model. Inclusion of these modifications has altered the resulting initial linear and angular motion of the projectile as it enters free flight from the motion reported in earlier papers. It has also modified the degree of agreement with experimental results. Additionally, mechanisms now exist within the model to provide some variability in the initial free flight projectile motion, resulting in target impact dispersions, heretofore not present in this simulation suite.
