文章介绍了北京卫星环境工程研究所采用激光驱动飞片系统将厚度5μm的铝质飞片发射到8．3 km/s。该驱动系统采用调Q钕玻璃激光,脉宽15ns,最大能量达到20J。针对热控材料、舷窗玻璃及OSR等外部表面功能材料开展了超高速撞击实验研究,取得初步研究结果。实验结果表明激光驱动飞片技术可很好地用于模拟微流星/空间碎片超高速撞击效应研究。
The article introduced the Beijing Satellite Environmental Engineering Research Institute to use a laser driven flyer system to emit aluminum flyer with a thickness of 5μm to 8.3 km / s. The drive system uses Q-switched neodymium glass laser, pulse width 15ns, the maximum energy of 20J. For the thermal control materials, portholes and OSR and other external surface functional materials carried out hypervelocity impact experimental study to obtain preliminary results. The experimental results show that the laser-driven flyer technology can be used to simulate the impact of the hypervelocity impacts of the micro-meteors / space debris.
