摘　　要：针对编队在民航领域的应用问题,论文提出了一种多阶段轨迹优化模型。首先对编队飞行进行描述,将整个航程划分为起飞爬升段、编队段、进近降落段,与现有航线网络相结合,以具体航路点确保相邻阶段的顺利连接;其次以民机直接运行成本为指标,采用中国民用航空局成本计算方法,确定编队飞机的机型;最后选取时间和燃料消耗为性能指标,建立飞机质心运动方程,设置起降机场、编队航段等约束条件。充分考虑航班各阶段飞行特性和约束,通过数值算例得到两航班编队运行后的最优轨迹,为航班的编队运行提供参考。Aiming at the application of formation in civil aviation,a multi-stage trajectory optimization model is proposed.Firstly,the formation flight is described,and the whole flight is divided into climbing,formation and approaching,which is combined with the existing airline network to ensure the smooth connection of adjacent stages with specific waypoints.Secondly,the direct operating cost of civil aircraft is taken as the index,and the cost system of civil aviation administration of China is adopted to determine the type of formation aircraft.Lastly,time and fuel consumption are selected as performance indexes to establish the equation of aircraft centroid motion and set constraints such as take-off and landing airports and formation flight segments.Fully considering the flight characteristics and constraints at each flight stage,the optimal trajectories of two flight formations are obtained by numerical examples,which can provide reference for flight formation operation.
