大气层外弹道目标温度变化研究

Study on Temperature Change of Atmospheric Outer Ballistic Target

针对弹道目标在飞行过程中的表面温度是导弹攻防两端关注的重点,简要介绍了弹道目标在大气层外飞行时的表面温度及红外辐射源;提出了大气层外弹道目标在飞行过程中的表面温度计算方法;重点针对弹头与诱饵的典型热物参数和大气层外不同的表面初始温度,分别计算了在阴影区与日照区弹头和诱饵表面温度随飞行时间的变化情况,发现弹头热惯量大,基本保持初始温度,诱饵热惯量小,迅速就会达到平衡温度,并采用实例对其进行验证。

Aiming at the ballistic target during flight surface temperature is the focus of missile attack and defense,the surface temperature and infrared radiation source of ballistic target in atmosphere outer are briefly introduced.A method for calculating the surface temperature of an atmosphere outer ballistic target during flight is proposed.Focusing on the typical thermal parameters of warhead and decoy and the atmosphere outside the surface of the different initial temperature,were calculated respectively in the shadow area and sunshine area warhead and decoy surface temperature with the change of flight time,found the warhead thermal inertia is big,basic to keep the initial temperature,decoy thermal inertia small,quickly will reach equilibrium temperature,and an example is used to verify it.
