摘要
根据数值传热学的方法模拟了目标表面温度分布,分析了隐身涂料的性能参数(短波吸收率αs、长波吸收率αl与表面发射率εt)对目标表面温度的影响;模拟了这些性能参数对红外探测系统作用距离的影响。分析结果表明:上述3种性能参数均会对目标表面温度产生影响。αs、αl与表面温度成正比,εt与表面温度成反比,影响幅度可达10 ℃左右;探测系统作用距离与背景温度、气象条件、探测器性能等多种因素相关,根据实际情况调整涂料性能参数可使作用距离最小。这些结果基本满足红外隐身涂料设计、选型与使用方面的实际需求。
Abstract
On the basis of the method of numerical heat transfer,the surface temperature of target was simulated. Then, the influence of the performance parameters of camouflage coating(shortwave absorptivity αs、longwave absorptivity αl、emissivity εt) on the surface temperature of target was analyzed. Finally, the influence of these performance parameters on the lock-on range of infrared detection system was also analyzed. The analytical results show that all of performance parameters would affect the temperature of target. αs and αl are in direct proportion to the temperature of target, and εt is in inverse proportion to that, the influencing range could reach to 10 ℃.Moreover,the lock-on range of detection system correlates to background temperature, weather condition, capability of detector and so on, and adjusting the performance parameters to the practical condition can shorten the lock-on range to least. These results can satisfy the practical requirements of design, selection and application of infrared camouflage coating.
