摘要
Abstract
The trans-atmospheric vehicles usually travel through the atmosphere,and the flight velocities change a-cutely.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 ve-hicle 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 tempera-ture 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.关键词
