摘　　要：应用最不利环境下的尾流运动特性,研究了近距平行跑道相关平行进近模式下配对飞机斜距、进近下滑角和机型组合对跑道间隔的影响,利用最小尾流间隔标准和NASA侧风统计数据,并根据机型参数,提出了跑道中心线间距和跑道头错开间距的确定方法。分析结果表明:当配对前后机的斜向间隔标准一定时,跑道头错开间距随中心线间距和配对后机下滑角的增大而减小;当配对前后机下滑角相同时,跑道头错开间距随中心线间距和斜向间隔标准的增大而减小;当跑道中心线间距为380m,前后机下滑角均为3°,斜向间隔标准为2 780m时,长沙黄花国际机场跑道头错开间距应不小于1 483m,符合国外已授权机场跑道参数。By using wake vortex movement characteristics under the most adverse environment, the effects of the slant range and approach glide angles of paired aircrafts and aircraft type combination on runway separation under the dependent parallel approach mode of closely spaced parallel runways were researched, the minimum wake vortex separation standard and crosswind statistical data of NASA were used, and the determination methods of runway centerline distance and threshold offset were put out based on aircraft type parameters. Analysis result shows that when the slant separation standard of paired leading and trailing aircrafts is a certain value, threshold offset decreases with the increases of runway centerline distance and the glide angle of paired trailing aircraft. When the glide angles of paired leading and trailing aircrafts are same, threshold offset decreases with the increases of runway centerline distance and slant separation standard. When runway centerline distance is 380 m, the glide angles of paired leading and trailing aircrafts are both 3°, and slant separation standard is 2 780 m, the threshold offset of Changsha Huanghua International Airport should be more than 1 483 m, which is accord with the runway parameter of foreign authorized airports. 3 tabs, 5 figs, 23 refs.
