摘　　要：针对某类跨大气层飞行器飞行过程中需要进出大气层,且飞行速度跨度大等特点,建立了不同空域、不同飞行速度下的机体头部受热模型。当在大气层内飞行时分别使用经验公式和Lees公式计算马赫数小于5和大于5时头部受热情况,当在大气层外飞行时建立了考虑太阳直射、地球反照和地球红外加热情况下的受热模型。利用普朗克定律得到了相同温度下不同波段的红外辐射能量占比情况。最后利用本方法对某类跨大气层飞行器进行了温度和红外辐射计算,得到的计算结果能够大致反映全航程头部温度和红外辐射变化情况。The trans-atmospheric vehicles usually travel through the atmosphere,and the flight velocities change acutely.The vehicle head's heating models for the different altitudes and velocities are constructed.When the trans-atmospheric vehicle is in the atmosphere,the experience equation and Lees equation are employed to compute the head's temperature for the velocities greater than and less than 5 Mach respectively.When the trans-atmospheric vehicle is out of the atmosphere,the irradiation of the sun's rays,the earth's albedo and the earth's infrared radiation is taken into account to compute the head's temperature.The Planck's law is used to compute the energy proportion of the different infrared wave bands at the same temperature.The proposed scheme is used to compute the temperature and infrared radiation of a type of trans-atmospheric vehicle,and the results can depict the variation of the warhead's temperature and infrared radiation of the whole trajectory.
