近距平行跑道运行受限于尾流间隔,尤其在侧风条件下风险增加。为提升近距跑道运行效率并减轻管制员工作负荷,本文提出了一种融合区域侧风场建模与尾流演化特性的动态间隔分析方法。首先,从航空器尾流特性角度分析了近距平行跑道运行模式;其次,基于栅格理论,构建了基于径向基函数的侧风模型,在此基础上,建立了侧风条件下的尾流特性模型;最后,以某机场为例,通过仿真分析,结果表明,现有间隔存在优化空间,为机场运行效率提升提供了科学依据。

The operation of closely spaced parallel runways is constrained by wake vortex separation requirements,with particularly heightened risks under crosswind conditions.To enhance operational efficiency and mitigate air traffic controllers' workload,this study proposes a novel wake vortex separation assessment framework for closely spaced parallel runways that incorporates regional crosswind effects.The research methodology encompasses three key components:First,the operational modes of closely spaced parallel runways are systematically analyzed through the lens of aircraft wake vortex characteristics.Second,leveraging grid theory,a radial basis function(RBF)-based crosswind field model is developed,subsequently enabling the establishment of a comprehensive wake vortex behavior model under crosswind conditions.Finally,through numerical simulations as a representative case study,the analytical results demonstrate that current separation standards possess potential for optimization.This investigation provides scientific support for optimizing airport operational efficiency while maintaining stringent safety criteria.
