摘要: 对钻地弹的弹体材料、弹体参数、气动性能、侵彻过载和侵彻深度等问题进行了研究。在此基础上，设计了模拟钻地弹，并进行了外场试验，试验取得了成功，且得到一些有益的结论。Abstract: In this dissertation, a model EPW is designed on the basis of theoretical analyses. Shell material and parameters of a projectile body, such as slenderness ratio and CRH (caliber radius head), were studied. Strength check and aerodynamic properties of a projectile body were investigated. The experimental examination of a projectile on penetrating semi-infinite concrete medium was performed. The values from theoretical prediction have good coincidence with the experimental data. Young equation can be applied to estimate the penetration depth.
