Modeling and simulation of airplane infrared characteristic

Airplane's infrared radiation simulation and modeling is an important branch for synthetic nature environment. It's needed to establish the infrared radiation model accurately according to airplane's status in present. In this paper, firstly, based on synthetic nature environment as well as aerodynamics, heat transfer theory, work principle of engine, airplane's infrared radiation characteristic models including airplane-skin and engine nozzle components, exhaust plume were established under current status. Then, moving airplane's infrared radiation characteristics with working status as the input was calculated and analyzed. Finally, airplane's infrared radiation results were obtained through the simulating model mentioned above under condition of different status. This modeling method will have an important effect on infrared platform detecting and real time scene generating in defense and military simulation system.
