Abstract：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 com-bined with the existing airline network to ensure the smooth connection of adjacent stages with specific waypoints.Secondly,the di-rect operating cost of civil aircraft is taken as the index,and the cost system of civil aviation administration of China is adopted to de-termine the type of formation aircraft.Lastly,time and fuel consumption are selected as performance indexes to establish the equa-tion of aircraft centroid motion and set constraints such as take-off and landing airports and formation flight segments.Fully consider-ing the flight characteristics and constraints at each flight stage,the optimal trajectories of two flight formations are obtained by nu-merical examples,which can provide reference for flight formation operation.
