Perspective Armour-Piercing Intermediate Cartridge Projectile

Abstract

Ongoing military conflicts, along with a constant evolution of individual protection devices, have shown an urgent need of development in terms of the armour piercing capability of standard infantry small arms ammunition. The following paper includes a brief overview of the existing armour-piercing intermediate rounds, in an effort to define the most reasonable design of a perspective armour-piercing projectile. Therefore, various projectiles were designed and evaluated in terms of their external ballistic performance for chosen initial conditions, followed by preliminary internal and terminal ballistic calculations that were performed in order to assess the most reasonable outcome.

Computational evaluation of assembly technique influence on ballistic performance of a bullet – non-linear relation between méplat size and the drag coefficient

“…The second is a reverse-jacketed projectile with a light tungsten penetrator extended from a jacket, clasped in an aluminum sleeve, also assembled from the front, and the last design with a tungsten penetrator centered with an aluminum sleeve, but fully jacketed by a copper jacket, assembled in a standard way, from the rear side of the bullet. The main factor differentiating the designs is the choice of assembly direction, creating a Full Metal Jacket or Semi-Jacketed projectile [6].…”
