Abstract

In this paper, a finite element analysis is used to present the distributions of thermal fields and stress fields at different Mach numbers at an altitude of 15 km in a standard atmosphere for the CVD ZnS plane window. Then, the radiation intensity distribution of the window is obtained according to the temperature distribution. The results show that the temperature increases sharply in a short time, then the temperature distribution remains stable. The stress reaches the maximum value in an extremely short time and then decreases. The imaging quality of the plane window rapidly decreases with increasing the Mach number. The thermal radiation effect is one key factor for the quality of infrared image.
