基于改进三阶段法的快速出口滑行道转出位置的确定方法研究

Research on the Position of the Rapid Exit Taxiway by the Three Segment Method

快速出口滑行道的设置是一种既经济又有效的用于提高跑道容量的方法,对提高机场运行效率有重要意义。论文将飞机自跑道入口至接地转出划分成三个阶段,分别为空中段、减速段与转出段。在分析三个阶段对应长度影响因素的基础上,针对某机场运行的典型机型,运用三阶段法对不同风力负荷条件下各阶段长度进行计算,最后引入机型累计运行比例的概念,确定快速出口滑行道的最终转出位置及条数,总结了三阶段法的计算步骤。实例验证该方法的可行性,对机场平面设计有一定的借鉴价值。

The location of the rapid exit taxiway is an economical and effective method for improving runway capacity,and it is important to improve the operation efficiency of airport.Distance required from landing threshold to a nominal turnoff speed was divided into three segments,they are the flare segment,the transition segment and the braking segment.Based on the analysis of the influence factors on the length of three stages and corresponded to the airport＇ s typical operations,the three-stage method was used to calculate the length of each stage under different conditions of wind load.Finally,the concept of cumulative run proportions was introduced to determine both the location and the number of the rapid exit taxiway,and it also summed up the calculation steps of the three segment method.
