摘要
为研究飞机尾向的红外辐射特性,首先利用计算流体力学软件FLUENT对飞机尾向流场进行了数值模拟,得到了尾向流场的温度分布情况;对飞机发动机尾喷管和尾焰的红外辐射进行了建模,得出了飞机尾向红外波段辐射强度的FLUENT计算结果,为红外制导防空导弹武器系统的设计和应用提供了参考依据。
First, a numerical simulation of the fluid field is performed in the opposite direction of the airplane by using CFD software - FLUENT, so the distribute situation of the temperature is attained. Then, a model of the radiation from the nozzle of the turbojet engine and exhaust gases of the airplane is built. The total radiance and that in the above IR band are obtained by FLUENT, which provides a basis for the IR guidance air- defense weapon system design and application.
