摘　　要：为解决空中交通流量管理中恶劣天气或流量受限下的航班改航问题,提出了基于几何算法的改航路径规划方法。首先,将几何算法应用于航班改航路径的规划研究,给出了初始改航点的确定方法。然后,从实际可操作性出发,分别给出了在转弯角度、航段距离和改航点数量限制下的改航路径修正方法。最后,运用本文提出的方法对我国西南雷暴多发地区的改航路径进行了研究。研究结果表明:本文提出的改航路径规划方法可安全有效的避开飞行受限区域,算法简单可行。To solve the reroute problem of air traffic flow management in severe weather or flow constrained areas, a new rerouting method based on geometry algorithm is proposed. First, the geometry algorithm is introduced and applied in reroute planning, and the method for determining primary reroute points is given. Then, according to the practical maneuverability, the reroute points are amended with limits on the heading change, the segment distance and the number of reroute points, respectively. Finally, the reroute problem caused by thunderstorms occurring in Southwest China is studied. The results show that the flow constrained area can be avoided safely and effectively by using the proposed method, and that algorithm is simple and feasible.
