红外末制导中的气动光学效应分析

Study on Aero-optical Effect in the Terminal Infrared Guidance

首先从热光效应和弹光效应的角度,分析了飞行器在大气层内飞行时,在气动热环境中的材料折射率与温度场和应力场的关系,得出了温度和应力对材料折射率的影响关系式,并进而探索气动光学效应下一步的研究方法。对认识气动光学效应机理具有参考意义。

By analyzing the relation between the refractive index and the temperature and the stress field of the optical window in the aero-dynamic environment, according to the thermal-optical effect and the elasto-optical effect, we obtained the relationship of the index-of-refraction and temperature and stress, and explored the further study method of the aero-optical effect. This work has the guiding meaning to understand the mechanism of the aero-optical effect.
