摘要
为了对坦克排烟热气的红外辐射特征进行分析,以坦克某一典型行驶工况为例,分析了不同高度和距离对穿透率的影响。基于最新版的HITRAN中的数据,针对算例给出的参数,利用高分辨率气体红外辐射计算模型计算得到了红外辐射特性。针对坦克某一工况下的排烟,利用高分辨率气体红外辐射计算方法对红外辐射特征进行了模拟计算,并进行了试验测试,最后对计算结果进行了比较。结果表明:大气的衰减作用主要是气体中的CO2和H2O分子的吸收作用造成的,在计算排烟热气的红外辐射特征时,需要考虑大气的衰减作用。相较于Curtis-Godson近似谱带模型法,采用高分辨率气体红外辐射计算模型能够更精确地得到光谱辐射亮度。
In order to analyze the infrared radiation characteristics of tank heat exhaust gas,the influence of different altitudes and distances on the penetration rate is analyzed by taking a typical driving condition of tank as an example.Based on the latest version of HITRAN data and the parameters given by the example,the infrared radiation characteristics are calculated by high resolution gas infrared radiation calculation model.Aiming at the smoke exhaust of tank under a certain working condition,the infrared radiation characteristics are simulated by means of high resolution gas infrared radiation calculation,and the experimental tests are carried out.Finally,the calculated results are compared.The results show that the atmospheric attenuation is mainly caused by the absorption of CO2 and H2 O molecules in gases.The atmospheric attenuation should be taken into account when calculating the infrared radiation characteristics of heat exhaust gas.Compared with Curtis-Godson approximate spectral band model method,the high resolution gas infrared radiation calculation model can obtain the spectral radiance more accurately.
