热烧蚀破坏是激光辐照过程中最常见且最易发生的现象。为防御激光辐照对壳体的热烧蚀破坏,以现有防护结构为基础提出了一种含液体金属的复合壳体结构,通过在壳体防护结构中设置一种能在常温下处于液体状态的金属材料,借助液体金属材料良好的导热特性及流动性能,在激光辐照时将光斑辐射部位所积聚的大量能量快速疏散,从而达到防护激光武器的目的。为明晰这种含液体金属复合壳体结构的抗激光性能,建立了相应的三维模型,并对其中典型的抗激光辐照过程进行了数值模拟和分析。结果表明,此方法可有效降低激光光斑照射表面的温度,从而延缓壳体发生软化的过程,由此还可实现更强大的抵御激光辐照的能力。新方法可进一步推广至各式反激光防护体系中。 Hot ablation damage is the most common and easiest phenomenon in laser irradiation. In order to prevent the heat ablation damage of the shell by the laser irradiation, a composite shell structure containing liquid metal is proposed based on the existing protective structure. By adopting a structure capable of storing the liquid in the shell at the normal temperature State of the metal material, with the liquid metal material good thermal conductivity and flow properties, the laser irradiation will spot a large part of the energy accumulated by the rapid evacuation, so as to achieve the purpose of the protection of laser weapons. In order to clarify the anti-laser performance of the liquid-metal composite shell structure, a corresponding three-dimensional model was established and the typical anti-laser irradiation process was numerically simulated and analyzed. The results show that this method can effectively reduce the laser spot irradiation surface temperature, thereby delaying the shell softening process, which can also achieve a more robust ability to resist laser irradiation. The new method can be further extended to all kinds of anti-laser protection system.
