摘要: 根据双层平行反应装甲飞板飞散变形的物理过程分析, 认为平行双层反 应装甲与射流作用过程分流为两个阶段, 在中间两飞板碰撞以前, 两组件的运动是独立的, 因此可按两个单个反应装甲先后与射流作用; 而中间两板碰撞以后即退出干扰作用, 按射流 与单个反应装甲作用计算. 并根据飞板运动规律得出了飞板碰撞退出干扰作用的时间. 通过 与实验和数值模拟结果比较表明, 理论分析过程与实验和数值模拟计算结果基本吻合.

Abstract: For the flying-panel in double parallel ERAs, the interaction between jet and double parallel ERAs can be devided into two phases. Before the collision with the middle panel, the jet can be considered to interact with two single ERAs. But after collision, the jet is considered to interact with a single ERA. Based on the movement of the flying-panel, the collision time of the middle panel can be obtained. Results of the simulation and experiment are in good agreement.
