真空环境下空间碎片超高速撞击试验研究

Impact Simulation of Hypervelocity Space Debris in Vacuum Environment

本文介绍了空间碎片的超高速发射技术及微小碎片的地面模拟试验。我国首次在真空环境下将激光驱动飞片技术应用到空间碎片的研究中。利用 13 5J的激光能量将厚 6 0 μm ,直径2mm的铝碎片驱动出去 ,速度可达 3 2km/s。

Novel technique has been successfully developed to simulate in vacuum environment the impact of the hypervelocity space debris.The velocity of the debris,aluminum disks 2 mm in diameter and 60 μm in thickness,can be accelerated to 3.2 km/s with the laser beams of an energy of 13.5 joule.Moreover,the damages caused by hypervelocity debris on thermal isolation paints and carbon/epoxy composite were tentatively assessed also.
