| 目的 通过开展激光对无人机用航空铝合金材料的缩比毁伤实验，为研究激光对无人机的毁伤特性及规律奠定基础，为激光武器的战技指标论证提供科学可靠的参考数据。方法 采用缩比模型法，利用激光对航空铝靶板进行毁伤实验，记录烧穿时间、光斑直径、激光功率等参数，并通过等效性修正实验对毁伤规律进行分析。结果 毁伤缩比实验中，随着尺度律cP的增加，航空铝板的平均击穿时间逐渐延长，击穿所需的激光能量密度基本符合线性增加规律。修正实验中，随着航空铝板厚度的增加，击穿时间逐渐延长，实验拟合曲线与理论曲线具有较好的一致性。结论 通过缩比实验与修正实验，可建立激光对航空铝合金材料的毁伤模型公式，根据激光参数推算毁伤阈值及击穿时间。 |

| The work aims to carry out equivalent-scale experiments of laser irradiation on aviation aluminum alloy materials for UAV, lay a foundation for the damage characteristics and laws of laser irradiation on UAV, and provide scientific and reliable reference data for demonstration of tactic indexes of high-power laser weapons. The equivalent-scale model method was used to conduct damage experiment on the aviation aluminum target by laser irradiation. Parameters such as breakthrough time, spot diameter and laser power were recorded, and the damage law was analyzed through the correction experiment. In the equivalent-scale experiments, with the increase of scaling law CP, the average breakthrough time of aviation aluminum plate gradually increased, and the laser energy density required for breakthrough basically conformed to the law of linear increase. In the correction experiments, the breakthrough time increased gradually with the increase of aviation aluminum alloy plate thickness, and the experimental fitting curve was in good agreement with the theoretical curve. Through the equivalent-scale experiments and correction experiments, the damage model formula of aviation aluminum alloy by high-power laser can be established, and the damage threshold and breakthrough time can be calculated according to the laser parameters. |
