摘　　要：为提高半穿甲弹的穿甲能力,设计了一种贫铀半穿甲实验弹。对实验弹的飞行稳定性进行了理论分析及数值模拟,两种方法计算得到的实验弹稳定储备量基本吻合,且能够满足实验弹的飞行稳定性要求。采用100mm滑膛炮,开展了贫铀半穿甲弹侵彻装甲靶板实验。实验结果表明,实验弹飞行稳定,与理论分析及数值模拟结果一致;实验弹在25°倾角下贯穿三层20mm厚GY4装甲钢,且回收到的弹体基本完好。通过对实验后的实验弹和靶板进行分析,认为贫铀半穿甲弹的穿甲能力较强。In order to improve the armor penetrating capacity of semi-armor-piercing penetrator,a special semi-armor-piercing penetrator with depleted uranium was designed.Its flight stability was analyzed based on theoretical analysis and numerical simulation.The value of stabilization storage obtained from above two methods is basically identical,and may meet the demands of flight stability.Armor steel target penetration impact experiments were carried out for the depleted uranium semi-armor-piercing penetrator by using a 100mm diameter smoothbore gun.Experimental results show that the flight of penetrator is stable and is in accord with theoretical analysis and numerical simulation.An armor steel target made of three layer GY4 with 20mm thickness was penetrated at an obliquity of 25 degree,and the penetrator was not damaged basically.So the depleted uranium semi-armor-piercing penetrator has a higher penetration capacity according to after experiment analyses of the penetrator and armor target.
