摘要: 设计并建立了用于飞行弹丸中段飞行状态实验室模拟的试验系统,测量获得了飞行弹丸的红外辐射特性.基于传热与辐射理论,分析了相关参数对实验结果的影响,获得飞行弹丸在一定飞行状态下的辐射特性变化规律.目标的初始温度和辐照条件是影响目标辐射特性的主要因素,自旋状态影响辐射特性的空间分布.试验测量与数值仿真和理论分析结果均具有很好的一致性,证明在实验室开展飞行弹丸的红外辐射特性模拟试验具有可行性.

Abstract: An experimental system based on the laboratory equipments was designed and set up to simulate the mid-course flying condition of projectile, and measured the infrared radiation characteristic data of flying projectile. Based on the conductive and radiant theory, the influences of simulation parameters on experimental results were analyzed, and the changing rules of radiation characteristic during the flying conditions were concluded. The initialize temperature of flying projectile and the radiation sources were the important parameters to the infrared radiation temporal characteristic of flying projectile, and the spin station has effects on the infrared radiation spatial characteristic. Comparing the results between the experiment, the numeric simulation and academic analysis, the results are correct and accordant, which sustain that the infrared radiation characteristic simulation experiment of flying projectile carried on the laboratory is feasible.
