摘要: 开展了25 mm火炮小尺寸缩比弹的正/斜侵彻实验。给出了实验方法、建议弹型和混凝土靶的设计。在620～820 m/s实验速度范围内，缩比弹结构保持完整。结合动能深侵彻弹的力学设计理论和笔者先前的理论工作，对正/斜侵彻的实验结果作进一步的总结，包括着靶姿态、靶体终点效应以及弹体结构变形。

Abstract: The normal and oblique penetration tests of reduced-scale earth penetrating weapon(EPW) are conducted. Various projectile structures and concrete targets as well as the experimental method are designed. The impact velocities vary in the range of 620～820 m/s, and the integrity of projectile structures are clarified. A large amount of experimental results of normal/oblique penetrations are summarized and the theoretical analyses are further conducted on the impact appearance, terminal ballistic effect and the damage of projectile bodies, etc.
