Infrared imaging missile’s aerodynamic heating simulation modeling methods

In order to assess the impact of aerodynamic heating effect of infrared imaging missile, through theoretical analysis of the variation of the missile during flight by aerodynamic heating, and research laboratories and large-scale pilot test data, pneumatic thermal effects modeling process and the normaldistribution method was first introduced to create a virtual prototype simulation model. Using the normal distribution, missile during flight rectifierhood by pneumatic thermal radiation and infrared images from the change process was simulated. Through digital simulation loop simulation and large-scale experimental verification, the method to establish the model was proved to be consistent with the actual situation. It can be used to assess the impact of aerodynamic heating effect on product performance information processing algorithms improvement.
