摘要
为了使点融合系统(point merge system,PMS)的优势能够在进场管理中推广,从PMS航空器运行控制设计方法和系统空间几何参数确定方法来分析PMS设计原理。引入航空器运行轨迹层次聚类方法,根据交通流聚类识别结果,分析航空器每类交通流的时空特性,设计终端区PMS的排序弧数量和融合点(mergeing point,MP)数量,构建网络容量评估模型。通过天津进近管制区的实例分析,用空域仿真软件平台进行仿真,仿真结果表明,PMS比当前进场系统容量增加了5架次/h(10.6%)。
In order to promote the advantages of point merge system(PMS)in the arrival management plan,it was analyzed from the aircraft operation control design method and the system space geometric parameter determination method.An aircraft trajectory hierarchical clustering method was introduced.Based on the traffic flow clustering recognition results,the spatio-temporal characteristics of each type of aircraft traffic flow were analyzed.The quantity of sequencing arcs and merging points(MP)of the terminal area merge system was designed.And a network capacity evaluation model was constructed.By analyzing the example of the Tianjin approach control area,airspace configuration system was used for simulation.The results showed that the capacity of the PMS increases by 5 flights/h(10.6%)compared with the current arrival system.
