超级单体雷暴下的改航模型研究

运用形态学的方法,从雷暴图中解析出飞行限制区,并以各个顶点的移动来描述雷暴天气的变化,从而建立危险天气模型。考虑到改航的可行性和便捷性,以最短航段距离和最大转弯角度为限制条件,在航线的两侧设置改航点,建立改航空间。在保证安全间隔的情况下,选择最短的改航路径,并按照航班优先等级确定各个航空器的改航顺序。仿真结果表明,所建模型可以在航路网受超级单体雷暴影响的情况下,为多个航空器规划出改航路径。

Research on rerouting model under supercell thunderstorm

In this paper,the thunderstorm map is processed directly,using the morphological method to resolve the flight restricted area,and describe the change of thunderstorm weather with the movement of each vertex,establishing the dangerous weather model.Considering the feasibility of rerouting and convenience,with the shortest distance and the maximum turning angle as the restriction condition,set rerouting points on both sides of the route,and establish rerouting space.In ensuring the safety of the case,select the shortest route to change,and in accordance with the priority level of flight,to determine the order of the aircraft in flight.The simulation results show that the model can be used to plan the flight path of the multi aircraft by the impact of the super single thunderstorm in the route network.
