    Abstract
  • Based on analyzing the conservation of energy of penetrator with enhanced lateral efficiency (PELE) the penetrating against metal target, a theoretical expression predicting the residual velocity of PELE perforating the target is obtained. By modifying De Marre semi-experience formula,the ballistic limit velocities of PELE penetrating into 2024 aluminum alloy and 45 #steel targets are also given. The theoretical predictions fit well with experimental or simulative results.
