| 摘 要： | 本文通过理论模拟和实验相结合的方法，对激光驱动靶丸超高速发射以及超高速靶丸撞击防护材料进行研究。首先利用辐射流体程序HYADES对靶的飞行速度进行了理论模拟预估，其次在中国工程物理研究院神光Ⅲ原型装置上开展实验验证，得到了将直径200 μm的铝球加速至44 km/s的实验结果，完成了高速铝球与防护材料撞击测试，并通过撞击形态验证了该材料的防护效果。本研究在模拟在轨航天器空间碎片撞击与防护方面具有十分重要意义。

| Abstract: | In this paper, by using a combination of theoretical simulation and experiment, the radiant fluid program HYADES was used to predict the flight speed of the target by theoretical simulation firstly. And the ultra high speed launch experiment of laser driven pellets was carried out on the SG Ⅲ prototype. The experimental results of accelerating aluminum balls with diameter of 200 μm to 44 km/s were obtained. In addition, the impact test of the high speed aluminum ball and the protective material was completed, and the protective effect of the material was verified by the impact shape. This research is of great significance in simulating the impact and protection of space debris from orbiting spacecraft. |
