以惠普尔 ( Whipple)防护屏结构为例 ,通过实验研究了铝合金柱状弹体以第一门槛值附近的速度正撞击 LY1 2合金防护屏的特点 ;研究了不同速度下防护屏损伤随速度的变化规律 ;对于速度在第一门槛值附近的速度正撞击 ,得到了撞击速度、防护屏及靶体厚度、防护距离的变化对防护屏及靶体作用的影响效果
Taking the structure of Whipple shield as an example, the characteristics of the LY1 2 alloy shield are positively impacted by the aluminum alloy cylindrical projectile near the first threshold value. The effects of the shield damage at different velocities The effect of impact velocity, the thickness of protective screen and the thickness of the target and the change of the protective distance on the effect of the protective screen and the target body are obtained for the speed positive impact near the first threshold value
