| 摘 要： | 采用火山岩模拟低密度脆性微流星体材料, 对航天器典型Whipple防护结构进行高速撞击试验. 试验表明, 火山岩弹丸在后板的损伤中, 主要体现在其能量的集中性上, 后板的损伤随着弹丸速度增加而增加, 前板的碎片也是后板损伤的重要因素, 其形成的坑比火山岩碎片云的大和深.

| Abstract: | Numerical hypervelocity impact experiments were carried out for spacecraft typical Whipple shield with lava simulated
meteoroids. It is shown that during the hypervelocity impact, the damage on the back plate is manifested by the concentration of energy, and it becomes more and more severe with the increase of impact velocity. The debris of the front plate also is an important damage element of the back plate, and the pits made by the debris are deep and big. |
