摘　　要：飞行器在执行任务过程中,需要根据三维空间和时间的气象信息变化、障碍物、威胁等信息以及飞行器自身的机动性能限制,计算出飞行航迹。主要通过基于遗传算法的航迹规划理论和应用MM5模式输出产品(风场、积冰、颠簸)信息,进行航迹路径的规划仿真验证与分析,给出了具有实际工程应用价值的飞行航迹。During implementing the task, the aircraft tracks the trajectory to finish the task. It is often calculated in term of weather variability in both 3-D space and time, obstacle, threaten, and itself maneuverability. The application of a GAs-based motion planning for aircrafts in flights was proposed. The planning made use of wind information from actual weather forecast databases in MM5 and considers areas of potential icing hazard and bumpiness hazard in MM5. The optimal trajectory with practice value trajectory and was given, after studying and simulating and analyzing.
