先进钻地弹概念弹的次口径高速深侵彻实验研究

同一般钻地弹相比，先进钻地弹撞击速度更高，侵彻深度更大。为实现高速侵彻，实验室研究常采用火炮次口径发射。本文中给出了高速侵彻的实验方法和火炮次口径发射实验技术，并开展了先进钻地弹概念弹的深侵彻缩比实验研究，取得了撞击速度约1.2 km/s的高侵彻能力的实验结果。同时对弹靶的变形破坏分别进行了分析，进一步验证了先进钻地弹的概念可行性。

Experimental study on deep penetration of reduced-scale advanced earth penetrating weapon

An advanced earth penetrating weapon (EPW) penetrates targets at higher velocity and achieves much deeper depth of penetration compared with a common EPW. The present paper introduces the experimental method of high-speed impact fired by artillery and the launch technique of sub-caliber projectile. An experimental study on the deep penetration of reduced-scale advanced EPW was conducted, and the highest impact velocity reached about 1.2 km/s. Analyses on the deformation and failure of projectiles and concrete targets were given in detail. Researched results confirm the feasibility of the concept of advanced EPW.
