摘要
针对歼击机机群跟进起飞的特点 ,从飞机尾涡的形成和发展入手 ,研究近地条件下的尾涡运动规律 ,导出了尾涡的诱导速度和漂移速度计算公式。并根据起飞过程中 ,后机受前机尾涡的影响范围仅局限于跑道宽度范围之内 ,对歼击机跟进起飞间隔时间的确定方法和影响因素进行了分析 ,为各型歼击机跟进起飞安全提供了理论依据。所得结论经过飞行验证 。
Starting with the formation and development of tail eddy of an aircraft,the paper mainly studies the motion law of the tail eddy on condition that the aircraft is near ground and gives the formulas of both induced velocity and drift velocity of the tail eddy;in view of the range of the tail eddy being within the width of the runway in the process of take off,the paper makes theoretical analysis of the determination of time slot and the affecting factors for the fighter.All view points in this paper have been verified in flight practices and suit well.
