Abstract

The PELE (penetrator with enhanced lateral efficiency) projectile is a new type of penetrator, which has both penetration and fragmentation effects. The damage characteristics of the PELE projectile have never been studied from the perspective of changing the shape of the projectile structure until now. This paper hopes to improve the damage power by changing the structural shape of PELE projectile, and the concept of a truncated cone-shaped PELE projectile is first put forward. In order to compare and analyze the damage power of the truncated cone-shaped PELE projectile and the conventional PELE projectile, six sets of simulation conditions were designed, and the penetration ability and fragmentation effect were used as the main evaluation indicators. According to the known structural parameters of the PELE projectile, the range of angle α of the truncated cone-shaped PELE projectile was determined to be 86.2°–90°. In addition, there is little difference in penetration ability between the two different types of PELE projectile; the damage effect of the truncated cone-shaped PELE projectile on the after-effect target is better than that of the conventional PELE projectile. It is hoped that through further structural optimization, the truncated cone-shaped PELE projectile will have more extensive engineering application value. View Full-Text
