| 摘 要： | 针对高超声速目标的红外辐射特性计算困难的问题,提出一种修正的工程计算方法。在传统气动加热工程计算方法基础上,考虑高超声速大气环境的动态影响,采用大气高度作为修正因子,构建高超声速再入飞行器目标表面气动加热的温度动态变化算法,并对典型飞行条件下的高超声速目标红外光谱辐射特性进行了计算分析。

| Abstract: | A modified and more accessible calculation algorithm is proposed to solve the problem of infrared radiation analysis of hypersonic target.Basing on the classic aerodynamic heating theory,considering key atmosphere environment′s influence,the algorithm chooses the altitude as modification parameter which is deduced with local density and temperature,and finally achieves the calculation model of aerodynamic hearting temperature of hypersonic reentry target.With the model,the infrared radiation of a typical hypersonic reentry flight setting is calculated and analyzed. |

| Keywords: | hypersonic reentry target infrared radiation aerodynamic heating altitude modification |
