飞行器的红外特性

飞行器红外特性研究对许多工程问题有重要意义。文中讨论了飞行器的三种主要红外辐射源即羽流，热空腔－羽流组合体，蒙皮的红外特性。较具体地讨论了飞机在非加力和加力状态下三种辐射源的辐射特性，包括空间特性和光谱特性。同时提供了实测数据作比较，还讨论了飞行器红外特性计算方法的发展及评估。

Infrared signature of flight vehicles

Infrared signature of flight vehicles is important for a lot of engineering problems, IR radiations from three major IR radiation sources including plume, thermal cavity plume combination and skin on flight vehicles are discussed in the paper. Spatial and spectral radiation performances of the three radiation sources on aircrafts are specifically discussed. The comparison of test data and computation results is presented. The development and evluation of computation methods of IR radiation from flight vehicles are also discussed.
