摘　　要：为解决航班因危险天气临时绕飞导致的航迹冲突问题,提出一种面向航迹运行(TBO)的4D改航回归航迹规划方法。首先,根据航空器性能限制,栅格化空域,使用蚁群算法与轮盘赌法,以改航路径最短为目标,生成三维空域内危险天气下的改航路径;然后,提出航迹回归概念,根据预计到达时间(ETA)计算改航速度,对齐时间得到4D改航航迹;最后,以我国中部某主要航段为运行场景,选取3个航迹回归点,采用“调速+等待”策略,计算避让危险天气的三维可行航迹,以燃油消耗与排放成本的计算结果与改航航迹产生的冲突为参考,评估各改航方案。结果表明:当选择最晚回归点时,改航方案3燃油消耗为5.9 t,温室气体排放量为26.3 t,是3种方案中消耗最少的,但需解脱冲突2次;选择最早回归点的改航方案1未与其他航班出现冲突,但燃油与排放相比方案3增加0.1%和0.2%。以上结果证实,该方案可实现危险天气下选取不同回归点时的4D改航回归航迹规划。In order to solve problems due to diversion caused by hazardous weather under TBO,a 4-dimension diversion and regression path planning method was proposed.First,the airspace according to the performance limitation was rasterized.The ant colony algorithm and roulette method were used to generate the 3-dimension path for hazard weather avoidance.The concept of diversion and regression path was defined.Combining the path with the estimated time of arrival,the speed of the diversion path was calculated.Through aligning the time,the 4-dimension diversion path was obtained.Finally,taking a route in Midwest China as the operation scenario,selecting three different reroute 4-dimension regression points,the path of avoiding obstacles caused by hazardous weather was obtained.The effects of three different diversion schemes were evaluated through fuel consumption and emission costs.The result shows:when the latest recovery point is chosen,the diversion scheme 3 has 5.9 t fuel consumption and 26.3 t greenhouse gas emission,which are the least of the three schemes,but the number of conflict resolution is twice that of others.The diversion scheme 1 with the earliest recovery point does not conflict with other flights,but the fuel consumption and emission are increased by 0.1%and 0.2%respectively compared with scheme 3.The results above show this scheme can be used to select different recovery points in the 4-dimension diversion and regression path planning process.
