Abstract

The push-out infrared seeker window in high-speed flight bears the functions of transmitting target infrared signal, maintaining aerodynamic shape and protecting internal imaging system. However, under the combined action of complex aerodynamic and thermal loads in high-speed flight, the infrared window may have the risk of performance degradation or even functional and structural failure. In this paper, the aerodynamic thermal simulation analysis method of the push-out infrared seeker is established. Based on the FLUENT fluid simulation analysis software, the flow field simulation analysis under typical flight conditions is completed, and the aerodynamic pressure and heat flow coupling distribution on the surface of the infrared seeker are obtained. The influence of flight parameters on the flow field and aerodynamic thermal coupling outside the infrared window is analyzed. On this basis, the distribution of temperature and stress of infrared window is obtained by finite element software simulation analysis, which provides guidance for infrared window material and structure design.
