考虑尾流影响的侧向双跑道机场的跑道容量研究

侧向跑道由于能够灵活面对强侧风的影响从而提高机场的效率,在我国大型机场的规划设计中逐渐推广。但是目前国内外在侧向跑道容量模型方面的研究较少,因此对侧向跑道的跑道容量模型的研究具有重大的意义。本文针对侧向双跑道系统,考虑了一组侧向跑道上航空器之间的尾流影响,通过计算尾流消散时间给出了侧向跑道航空器的放行条件,同时利用时序图得出在侧向双跑道系统中连续进场航空器间插入离场航空器的条件,从而构建出侧向双跑道系统的跑道容量理论计算模型;最后以成都天府国际机场一期跑道为算例,计算出尾流影响下侧向双跑道系统的小时容量,并给出航班起降架次表,验证了模型的正确性,为侧向跑道机场的跑道容量理论计算提供了参考。

Runway Capacity of Lateral Double-Runway Airport Considering Wake Effect

Lateral runways have gradually popularized in the planning and design of large airports in China because they can flexibly face the influence of strong crosswind and thus improve the efficiency of airports. However, few studies on lateral runways have emerged globally, and research on runway capacity model of lateral runways is of great significance. In this paper, the wake effect between aircraft on a set of lateral runways is considered for the system with two lateral runways. The release conditions of aircraft on the lateral runways are given by calculating the wake dissipation time. At the same time, the conditions for inserting departing aircraft between continuously approaching aircraft in the system with two lateral runways are obtained by using the timing chart. Thus, the runway capacity calculation model of the system with two lateral runways is constructed. Finally, Chengdu Tianfu International Airport Phase I runway is taken as an example to calculate the hourly capacity of each runway under the influence of wake flow, and a flight take-off and landing schedule is given to verify the correctness of the model, which provides a reference for the theoretical calculation model of runway capacity for lateral runway airports.
