摘要
飞机红外辐射建模与仿真研究是综合自然环境仿真的重要分支,根据目标飞行状态建立红外辐射模型是当前仿真的需求。文中基于综合自然环境、空气动力学、传热学和发动机工作原理,建立了飞机在当前飞行状态下蒙皮及发动机尾喷管、羽流的红外辐射强度特性模型。在当前飞行状态为输入情况下,分析并计算了运动飞机的红外辐射特性,并通过仿真获到了飞机在不同状态下的红外辐射结果。此建模方法对国防军事仿真系统中的平台红外探测与实时红外场景生成具有重要意义。
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.
