Projectile/Sabot Discard Aerodynamics
Abstract
An engineering analysis procedure which describes the sabot discard process for gun-launched projectiles has been modified in order to provide an improved tool for investigating the effects of sabot, projectile and launch parameters upon near field dispersive forces. Experimental test data generated by BRL has been used to formulate an improved engineering model of the interaction flow field which develops about the projectile/sabot petal package during the removal process. The experimental data indicated that individual compression wave intersections and reflections are present within the annular flow passage. In order to model this behavior, an integrated flow element approach utilizing local shock/expansion procedures has been evolved.
