【摘要】：近年来,空中交通流量不断增加,有限的空域资源与航空市场日益增长的运输需求矛盾加剧,飞行冲突也变得日益严重,因而亟需对空域进行重新规划。空域规划过程中,除了提高空域资源利用率,还需满足一定的空域安全标准,因而冲突、碰撞风险估计在规划过程中是至关重要的,空域规划需建立在安全评估基础上。国内外对空域安全都有一定的研究,都侧重于对空域的飞行安全间隔的研究,同时国外还针对空域规划各个层次的空域安全进行了初步研究,总的来说,对空域规划的空域安全仍缺乏更深层次的研究。本论文主要对基于性能导航(Performance Based Navigation,PBN)的空域规划安全进行研究,首先引入PBN这一概念,考虑PBN空域规划各层次航空器飞行特点,从而确定PBN空域规划安全评估模型框架;然后依据PBN空域战略规划层次的空域运行特点,综合考虑发生冲突风险的概率及交通流情况,并以冲突风险值为指标,建立相应的安全评估模型;接着建立PBN空域战术规划安全评估模型,分别分析一定安全目标水平下冲突风险的持续时间和严重程度;最后,在空域结构及交通流进出点确定情况下,综合考虑天气状况、航班到达流、管制员工作负荷等因素,确定PBN空域运行规划安全评估模型。各个模型可以用于空域扇区的安全评估,有助于制定合理的空域规划方案,平衡冲突风险和飞行需求,为专家决策提供支持。
[Abstract]:In recent years, the air traffic flow is increasing, the contradiction between the limited airspace resources and the increasing transportation demand of the aviation market is intensified, and the flight conflicts are becoming more and more serious, so it is urgent to replan the airspace. In addition to improving the utilization of airspace resources, it is also necessary to meet certain airspace security standards. Therefore, collision risk estimation is very important in the planning process. Airspace planning needs to be based on safety assessment. There is a certain amount of research on airspace security both at home and abroad, with emphasis on the study of flight safety intervals in airspace. At the same time, foreign countries have also carried out preliminary studies on airspace security at all levels of airspace planning. There is still a lack of further research on airspace security in airspace planning. In this paper, the safety of airspace planning based on performance Based navigation is studied. Firstly, the concept of PBN is introduced, and the characteristics of aircraft flight at all levels of PBN airspace planning are considered. Then, according to the operational characteristics of PBN airspace strategic planning level, the probability of conflict risk and traffic flow are considered synthetically, and the conflict risk value is taken as the index. Then the PBN airspace tactical planning security assessment model is established to analyze the duration and severity of the conflict risk under a certain security target level. Finally, When the airspace structure and the traffic flow point are determined, the weather condition, the arrival flow of the flight, the workload of the controller and so on are taken into account. Each model can be used to evaluate the safety of airspace sector, which is helpful to formulate a reasonable plan of airspace planning, balance the conflict risk and flight demand, and provide support for expert decision-making.
