Investigation of Oblique Penetration I: The Effects of Penetrator Leading End Shapes on Unyawed an Yawed Impacts

Abstract

This report investigates the effects of nose shapes on simple oblique and yawed oblique impacts. For simple oblique penetration there is a significant amount of rod tip erosion. Novel shaped noses can be designed which minimize the amount of mass lost in erosion and which create efficient craters sufficient to allow passage of the upstream portion of the rod. Gains brought about by novel rod tip designs are not as evident in the yawed oblique impact case as in the simple oblique impact case. The gains made in the axial direction are obscured somewhat by the additional loading due to slot formation. However, nose shapes seem to affect the degree and nature of this load and may provide a means of reducing the damage caused by slot formation.
