Abstract:

利用二级轻气炮发射2017-T4铝球弹丸,高速正撞击5052铝网防护结构,模拟空间碎片对航天器防护结构的高速撞击作用,研究了铝网防护结构的高速撞击防护特性。在面密度相同的情况下,分析了影响铝网填充防护结构高速撞击防护性能的铝网尺寸效应及组合效应。实验撞击速度为2.90~4.95km/s,弹丸直径分别为3.97和6.35mm,撞击角为0°。实验结果表明:厚度为0.5mm的2A12铝板对高速撞击铝球的初次破碎能力优于相同面密度的5052铝网层,但作为填充介质,5052铝网层比2A12铝板具有更好的保护后板作用;在一定的丝径范围内,丝径越小,撞击防护效果越好;前网后板填充层比前板后网填充层具有更好的均匀破碎效果。
