气动热效应对某红外导引头影响分析

摘要

导弹高速飞行时所产生的气动热,将影响探测器正常成像质量,从而影响导弹的命中精度和导引头的作用距离.由于新型隔热材料的采用,气动热对导引头性能影响减小很多.采用ANSYS软件对某导弹的气动热效应进行仿真,为高速导弹气动性能分析及其环境失效研究提供参考.%High-speed flying missile will cause aerodynamic heating effect in atmosphere and affects the detector normal imaging inside infrared seeker, which will certainly affect missile's hit accuracy and detection range coverage of seeker. The aerodynamic heating effect to infrared seeker can be reduced by using new material of heat insulation. ANSYS software was applied to simulate aerodynamic heating effect of a missile. The purpose was to provide reference for aerodynamic heating performance and environmental failure analysis of high-speed missile.
