摘要

摘要: 设计了弹头形状和弹体结构合理的金属侵彻弹体，利用口径为320 mm的平衡炮，采用次口径加载技术，将直径为136 mm、长度为680 mm、质量为52 kg的金属侵彻体加速到1300 m/s,去侵彻尺寸为3 m3 m6 m的钢筋混凝土靶。实验结果表明：次口径弹托与弹丸完全分离，弹体飞行姿态稳定，飞行攻角小于2，弹体侵彻6 厚的钢筋混凝土后剩余速度约为260 m/s。实验后回收的金属弹体结构完整，仅弹体头部存在一定塑性变形，弹体质量损失约1.2%，长度缩短约0.7%，弹靶作用过程的侵蚀现象不明显。

Abstract: A metallic penetrator with the mass of 52 kg was designed by considering reasonably its structure and head shape. Based on the sub-caliber launch technology, the designed penetrator was accelerated to 1 300 m/s by a Davis gun to experimentally penetrate a six-layer reinforced concrete target with the size of 3.0 m3.0 m6.0 m. The penetration experiment displays that the sub-caliber penetrator departed distinctly from the Davis gun，its flight attitude was stable, the attack angle was less than 2, and the residual velocity was about 260 m/s after the penetration of the penetrator into the reinforced concrete of 6 m thickness. After the penetration experiment, the recovered penetrator was intact and only a little plastic deformation on the penetrator head. And the penetrator mass lost around 1.2 percent, its length shortened 0.7 percent, and the erosion phenomenon was unconspicuous.
