下一代航空运输系统中的空中高速性能基导航航路具有单向、无交叉、对性能限制、高密度运行等特点.以下一代航空运输系统的运行规则为基础,引入航班交通流流量、密度、速度基本函数和关系等式;结合地面交通流理论,对空中高速性能基导航单层航路建立了航班流模型.再通过对航路航班流速度-密度关系的分析,推导出稳定平衡状态下的流量-密度模型.模型可用于航路流量和容量评估,用其对终端区航班容量进行研究,结果符合相关数据.模型明确了缩减航空器尾流间隔可以提高终端区航路流量.
Next-generation air transport system in the air high-speed performance-based navigation route with unidirectional, no crossover, performance constraints, high-density operation, etc. Next generation air transport system based on the rules of operation, the introduction of flight traffic flow, density, speed Basic function and relational equation of the flight speed of airway are discussed.According to the ground traffic flow theory, the flight flow model is established for the airborne high-speed performance navigation monolayer route.According to the analysis of the speed-density relationship of the flight route flow, the steady- Density model.The model can be used to evaluate the traffic volume and capacity of the route, and the flight capacity of the terminal area is studied by using the model, and the result is in line with the relevant data.The model defines that reducing the aircraft wake interval can improve the traffic volume in the terminal area.
