摘要: 为提高雷暴天气下的飞行安全,降低管制员雷达引导绕飞雷暴的工作负荷,避免飞行冲突,进而减少多航空器在雷暴天气下改航的状况,首先构建编码空域信息矩阵,用栅格化的方式描述雷暴危险区,明确雷暴危险区对航空器产生的安全威胁;然后针对发生冲突且需要绕飞雷暴危险区的前后2架航空器,提出基于冲突避让的改航路径规划模型,并确定其约束条件;最后引入人工势场法,改进传统蚁群算法中的启发信息因子,以提高模型路径搜索的有效性。结果表明:运用改航路径规划模型可以得到块状、带状、散点状危险区避让冲突的改航路径规划仿真图;经规划后的路径,可避免2架航空器发生冲突,采取合理避让措施。

Abstract: This study is conducted to improve flight safety under thunderstorm weather, reduce controllers' workload of guiding aircrafts to avoid thunderstorms with radar so as to prevent flight conflicts as well as to reduce the number of aircraft diversions during thunderstorms. Firstly, the coded airspace information matrix was constructed, the thunderstorm danger zone was described by rasterization and the security threats caused by the zone to the aircraft were clarified. Then, the diversion route planning model for two aircrafts which encounter conflicts and need to avoid the thunderstorm danger zone was proposed and the constraints were confirmed. Finally, the artificial potential field method was introduced to improve the heuristic information factors in traditional ant colony algorithm further to improve the effectiveness of model route search. The results show that the model can be used to obtain a simulation map of the diversion route for conflict avoidance in block, banded and scattered danger zones. The planned route enables two aircrafts to achieve conflict avoidance with viable measures.

Key words: flight safety, thunderstorm danger zone, artificial potential field method, ant colony algorithm, conflict avoidance, diversion route planning
