摘　　要：针对双机编队飞行长机尾流对僚机的气动耦合效应问题进行了研究。以同型飞机双机编队为研究对象,首先建立了长僚机双机编队的尾流效应理论模型,分析了长僚机不同相对位置时长机尾流对僚机升力和阻力的影响;然后,对双机松散编队、侧后方密集编队以及正后方编队的僚机升力系数、阻力系数以及滚转力矩系数进行分析,得到长机尾流对僚机的“增升减阻”效果以及飞行安全的影响;最后,针对双机密集编队队形,细化研究了不同的迎角和垂直距离时,长机尾流对僚机气动特性的影响,统筹考虑“增升减阻”效果以及飞行安全两方面影响,给出编队配置的最佳队形,提出密集编队飞行操纵建议。The aerodynamic coupling effect problem of the wake flow of the lead aircraft on the wing-man in a two-aircraft formation flight is studied.Firstly,a theoretical model of the wake flow effect for the lead-wingman two-aircraft formation is established using a formation of two identical aircrafts as the research subject,and the impacts of the wake flow of the lead aircraft on the lift and drag of the wingman at different relative positions are analyzed.Then,an analysis is conducted on the lift coefficients,drag coefficients,and roll moment coefficients of the wingman in loose formation,close formation from the side,and formation directly lead aircraft.This reveals the“increasing lift and re-ducing drag”effect of the wake flow of the lead aircraft on the wingman,as well as that on flight safety.Finally,for the two-aircraft close formation,a detailed study is conducted on the wake im-pact of of the leader on the aerodynamic characteristics of the wingman at different angles of attack and vertical distances.Taking into account the effects of“increasing lift and reducing drag”as well as those on flight safety,the optimal formation configuration for the formation is determined,and suggestions for flight maneuvers in a close formation are proposed.
