中文摘要: 为了预估低能见度时航空器起降间隔变化,提高跑道使用效率,减少航班延误,提出机场Ⅱ类运行下航空器起降间隔模型。首先,分析Ⅱ类运行下航空器起降运行程序,细化航空器起飞、降落、进入跑道、脱离跑道过程。其次,基于Ⅱ类运行规定建立航空器起飞、降落模型。然后,定义元胞结构,引入避让减速规则和脱离跑道条件,定义航空器滑行元胞自动机模型。最后,将管制规则抽象为约束条件并量化航空器起降间隔。以乌鲁木齐机场为例进行仿真验证,计算机模拟得到机型比例、起降比例、临界区长度、脱离时间等参数对起降间隔、间隔标准差等值的影响。数值分析表明,Ⅱ类运行时起降间隔较大,峰值为228.6 s,降落、起飞容量仅为正常运行情况下的60%、90%,间隔标准差峰值为74 s,是正常运行情况下的1.64倍。脱离道位置对前机脱离时间影响较大,是连续降落间隔增加的主要因素。仿真结果表明,该模型能量化关键因素对起降间隔的影响,仿真结果与实际运行相符,能为提高机场Ⅱ类运行效率提供理论依据。
Abstract:In order to estimate the change trend of aircraft taking off and landing separation in case of low visibility, improve the efficiency of runway use and reduce flight delay, an aircraft taking off and landing separation model in airport category Ⅱ operation was proposed. Firstly, the taking off and landing operation procedures under the category Ⅱ operation were analyzed to detail the process of aircraft taking off, landing, lining up and vacating runway. Secondly, a taking off and landing model was established based on the category Ⅱ operational regulations. Then, the cellular structure was defined, the rule of avoiding deceleration and the condition of vacating runway were introduced, and a cellular automata model of aircraft taxing was defined. Finally, the control rules were abstracted as constraint conditions and the taking off and landing separations were quantified. An example of Urumqi airport was used to verify the simulation. The change trends of taking off and landing separation and separation standard deviation were obtained through computer numerical simulation by setting different values for parameters such as the ratio of aircraft type, the ratio of landing and taking off, the length of the critical area and the time of vacating. The experiments demonstrated that in categoryⅡoperation,the separation was large, with a peak of 228.6 s. The capacity for landing and taking off were only 60% and 90% of the normal operation conditions. The peak of separation standard deviation was 74 s, which was 1.64 times of normal situation. The vacating position was the main factor for the increase of continuous landing separation. Results showed that the model could quantify the influence of key factors on the taking off and landing separation. The simulation results are in line with the actual operation, and provides theoretical foundation for improving efficiency in categoryⅡoperation.
