An Influence Analysis Method of Wake Turbulence in V-open Runway Operation Mode

Abstract

In the design of large airports in China, Beijing Daxing international airport and Chengdu Tianfu international airport have adopted V-open runways. However, there is a relative lack of operational regulations for the V-open runway at home and abroad, it is of great significance to study the mutual influence of wake of aircrafts running parallel runway and V-open runway at the same time. The formation process, change period and movement characteristics of aircraft wake are systematically studied, and the wake movement model affected by the anisotropic wind speed is established. Taking the east one and the north one runways of Chengdu Tianfu international airport as an example, the influence of the wake on each other is analyzed by using the wake movement model. The specific values of the coverage of wake dangerous area under different conditions are obtained. Calculation results show that when the runway east one and the runway west one takes independent parallel instrument approach mode, the track offset angle of go-around aircraft from the runway east one is greater than 20.3°, its wake will affect aircraft departing from runway north one.
