摘要
Abstract
A robust EP(earth penetrator) what we call WHA-ballast EP is designed to improve penetration performance. A specific WHA(tungsten heavy alloy) component is embedded in the WHA-ballast EP case as a ballast to increase the cross-section mass(penetrator weight to cross section area ratio) which plays a dominant role in EPW(earth penetrator weapon) penetration capability. The laboratory and field tests of the scale WHA-ballast EP penetration have been conducted. The concrete target and discarding sabot used in the experiments are designed. The experimental results show that the penetration performance of the WHA-ballast EP is improved significantly compared with data from the conventional EP tests, and the penetrator can survive severe penetration environment. Study was carried out on the hp(depth of penetration) relationship between the scaled-down EP and the full scale one. The result of the study is presented in summary form expressing the relationship between hp of scaled penetrator and the scale factor κ with excellent agreement with test data.关键词
