Low fineness ratio kinetic energy penetrators
Abstract
We have modeled the penetration process of a low fineness ratio, heavy metal kinetic energy projectile impacting a semi-infinite steel target at and above typical ordnance speeds using the Lawrence Livermore National Laboratory (LLNL) two-dimensional, finite difference code, GLO. We have also performed ballistic experiments using an LLNL two-stage light gas gun to gather data over a range of impact speeds from 2.0 to 7.5 km/s. On this basis, we have constructed relationships between penetration efficiency (total penetration/projectile length), projectile fineness ratio (projectile length/profile diameter), and projectile impact speed. Furthermore, we have constructed a three-dimensional surface of penetration efficiency for tungsten alloy projectiles impacting semi-infinite steel. From these constructions, it is straightforward to determine minimum kinetic energy requirements at a target for a prespecified level of penetration. 12 refs., 16 figs., 3 tabs.
