摘　　要：国内近距错列平行跑道的主流运行模式是隔离平行运行,由于该模式采用了较为保守的尾流安全间隔,在航空器离场相对集中时段会出现一定程度的放行拥堵问题。对此,文章选取了双起双落相关运行模式,以近距错列平行跑道为研究对象,结合起飞尾流的演化特征,提出一种基于气象条件的航空器起飞尾流动态缩减方法,并以黄花国际机场的跑道主要参数为仿真参考条件,运用所搭建的尾流动态缩减仿真系统进行了仿真验证。仿真结果表明文章中所提出的基于滚转力矩系数的起飞尾流遭遇度量是合理的,且尾流间隔可以缩减至100 s以内。The mainstream operation mode of close staggered parallel runways in China is of isolated and parallel operation.Since this mode uses a more conservative wake safety separation,a certain degree of congestion may occur during the relatively concentrated period of aircraft departure.In this regard,the paper selects the dual takeoff and double landing related operation mode,takes the close staggered parallel runways as the research object,combines the evolution characteristics of the takeoff wake,and proposes an aircraft takeoff wake dynamic reduction method based on meteorological conditions.The main parameters of the airport’s runway are the simulation reference conditions,and the simulation verification is carried out by using the built-up wake dynamic reduction simulation system.The simulation results show that the takeoff wake encounter metric based on the roll moment coefficient proposed in the paper is reasonable,and the wake separation can be reduced to less than 100 s.
