摘要: 针对防御小法线角入射的长杆弹的需要而设计出了一种新型反应装甲结构。通过分析新型反应装甲结构对长杆弹运动速度和姿态的干扰，得出在长杆弹质量守恒的情况下的动力学方程，并进行反应装甲抗长杆弹侵彻实验。结果表明，新型反应装甲能够有效的干扰小角度长杆弹的飞行姿态并造成动能损失，可提高对长杆弹的防护效果。

Abstract: A new explosive reactive armor (ERA) structure was designed. A series of dynamic analyses were carried out on the interferences of the new ERA structure with the motion velocity and attitudes of the long-rod projectiles, the corresponding dynamic equations were obtained for the long-rod projectiles in the mass conservation condition, and the protection effectiveness of the new ERA structure was experimentally validated. Investigated results show that the new ERA can disturb effectively the motion attitudes of the long-rod projectiles with small yaw angles and induce their kinetic energy decrease markedly.
