Effect of Nose Shape on Depleted Uranium (DU) Long-Rod Penetrators

摘要

The ballistic performance of model scale U-3/4%Ti long-rod penetrators with threedifferent nose-shape designs (blunt nose, conical nose, and frustum cone) were evaluated. The target matrix included semi-infinite rolled homogeneous armor (RHA) and two finite RHA targets, one at normal incidence and one at high obliquity, but with the same line-of-sight thickness. The results reflected the same trends as observed for a previous tungsten alloy penetrator study, demonstrating that the nose-shape effects are independent of penetrator material.
