航线天气预报中航迹规划仿真研究

Researches of Computer Simulation on Path Planning in Airway Weather Forecast

在实际的航线天气预报中,应该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。这里主要通过基于进化算法的动态路径规划思想,应用MM5模式输出产品(风场、积冰和颠簸)信息,进行航迹路径的规划仿真验证与分析,给出了具有实际应用价值的预报飞行航迹。

During implementing airway weather forecast, the aircraft should be calculated in term of weather variability in both 3-D space and time, obstacle, threaten, and itself maneuverability. The application of an EA-based dynamic path planning for aircrafts in flights was proposed. The planning made use of wind information from actual weather forecast databases in MM5 and considered areas of potential icing hazard and bumpiness hazard in MM5. The optimal trajectory with practice value forecast trajectory was given, after studying , simulating and analyzing.
