Analysis of Aerodynamic Heating Effect on Infrared Seeker

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.
