具有绕滑的跑滑系统航空器滑行策略研究

为了应对空中交通流量的增加带来的挑战，很多繁忙机场建立了具有平行跑道的跑道系统来提高机场容量。绕行滑行道（End-around Taxiway，EAT）是提高具有近距平行跑道的繁忙机场运行效率的新型滑行道。本文根据具有绕行滑行道的跑滑系统的运行特点，将航空器在跑滑系统中的运行分为直接穿越、选择绕滑、等待-穿越三种滑行策略。提出具有绕行滑行道的跑滑系统滑行效率的概念，将航空器的滑行燃油最少和滑行时间最短作为协同优化目标，并结合绕行滑行道的运行规则、效率优先级作为约束条件，建立航空器地面滑行策略优化模型。从而根据该模型，选出最优的滑行策略。算例分析表明，绕行滑行道的使用可有效提高跑滑系统的滑行效率。

Study on Aircraft Taxiing Strategy of Run-taxi System with End-around Taxiway

In response to the challenges posed by the increase in air traffic, many busy airports have established runway systems with parallel runways to increase airport capacity. End-around Taxiway (EAT) is a new type of taxiway to improve the operational efficiency of busy airports with closely spaced parallel runways. In this paper, according to the operational characteristics of the run-taxi system with End-Around Taxiway, the operation of aircraft in the run-taxi system is divided into three taxiing strategies: direct crossing, selective EAT, and waiting-crossing. The concept of taxiing efficiency of the run-taxi system with EAT is proposed, and the minimum taxiing fuel and minimum taxiing time of the aircraft are taken as the synergistic optimization objectives, and the operating rules of the EAT and the efficiency priority are combined as the constraints to establish the optimization model of aircraft ground taxiing strategy. Thus, according to the model, the optimal skidding strategy is selected. The analysis of the algorithm shows that the use of the bypass skidway can effectively improve the skidding efficiency of the running skid system.
