终端区进场航线交叉点通行能力研究

Research on Traffic Capacity of Terminal Area in the Intersection Point of Approach

终端区航线交叉点是空中交通运行的瓶颈,其通行能力是表征交叉点运行状态的重要指标,深入研究交叉点的通行能力,能够为进离场航线优化及航线网规划提供理论指导,并为减少航班延误提供必要的技术支持。借鉴地面道路交叉口通行能力已有研究成果,依据终端区空域结构及航空器飞行特征,创新地提出终端区进场航线交叉点通行能力定义,建立了计算模型,深入分析了航空器飞行速度、机型组合、航线夹角对通行能力的影响。以天津机场终端区为例,计算进场航线交叉点CG点的通行能力,进行了实例验证及分析。

Terminal area route intersection is the bottleneck of air traffic,the traffic capacity is an important index to characterize the operation state of intersection,it can provide the theoretical guidance for the approach and departure routes and route network planning and optimization,in order to reduce the flight delay to provide the necessary technical support. From the ground road intersection the capacity of the existing research results,based on the flight characteristics of aircraft airspace structure and terminal area,the definition of the terminal area near route intersection traffic capacity calculation model is established,in-depth analysis of the aircraft flight speed,aircraft mix,impact angle on the capacity. Taking the terminal area of Tianjin Airport terminal area as an example,the capacity of CG point of route intersection is calculated,and the example is verified and analyzed.
