采用金刚石模拟高脆性、高熔点微流星体材料,对航天器典型Whipple防护结构进行高速撞击试验. 试验表明,撞击产生的高温高压效应导致金刚石部分或全部转化为石墨,金刚石对防护结构的损伤主要体现在中低速阶段,当撞击速度大于4.3 km/s时,对后板的灼烧损伤极为显著.

In this paper numerical high-speed impact experiments on typical spacecraft Whipple shield with diamond simulated meteoroids have been done. Tests show that some physical effects such as high temperature and high pressure resulted in some or all of diamond into graphite in the process of high-speed impact. The damage of diamond on shield mainly manifests in low-speed and medium-speed. When velocity is more than 4.3 km/s, the scorch damage of diamond on the rear board is extremely significant.
