Research On Application And Optimization Of Point Merge System In Airport Terminal Area

In recent years,with the increasing number of domestic airport flights and the growth in the number of passengers choosing to travel by air,this has led to an increase in controller workload,frequent aircraft conflicts and environmental pollution in the terminal area under the operation of the current approach flight procedures at Shuang Liu Airport,which has directly affected the efficiency of approach aircraft operations in the airport terminal area.In addition to reducing the service quality of passengers and the operational efficiency of the airport,it also causes the serious exceedance of carbon dioxide and other gas emission standards in the terminal area.At present,the current approach flight procedures in the terminal area of Shuang Liu Airport can no longer adapt to the future rapid development of the civil aviation industry resulting in an increase in the number of flights,and the study of the approach procedures has become a key task to improve the operational efficiency of the airport terminal area.Point Merge System(PMS),as a new approach procedure,has become a new technology to optimize airspace,increase terminal area operation capacity,reduce controller workload and improve airspace operation efficiency.In this thesis,the application and optimization of Point Merge System in the terminal area of Shuang Liu Airport is studied in the light of the operational characteristics of Point Merge System and the airspace operation environment of the terminal area of Shuang Liu Airport,so as to help promote the use of Point Merge Technology in large domestic airports in the future.In this thesis,we firstly reviewed the operation rules of point fusion technology and the current situation of domestic and international research,and analyzed the parameter requirements of point fusion program design;secondly,we analyzed the operation environment,distribution of obstacles and restricted areas in the airspace of the terminal area of Shuang Liu Airport through map work,and obtained the constraints of the initial point fusion design program of Shuang Liu Airport;and statistically analyzed the typical daily flight plan of Shuang Liu Airport,and obtained the initial point fusion approach program for normal load approach traffic flow of 25 aircraft movements/h and high load approach traffic flow of 40 aircraft movements/h.Then,based on the obstruction flow network model,the initial point fusion program was analyzed for the operation of high-load approach traffic flow.Then,based on the blocking flow network model,the operation of the initial point fusion program is analyzed for the high load approach traffic flow,and the bottleneck is(AN31,UU702)under the high load approach traffic flow,and the optimized point fusion approach program is proposed for the initial design scheme;finally,SIMMOD simulation software is used to simulate the current approach program,the initial point fusion approach program and the optimized point fusion approach program under different traffic flow loads,and the simulation of the point fusion system improves the operation time of Shuang Liu Airport by 4469 s and 1658 s,thus verifying the effectiveness and feasibility of the design scheme of the point fusion procedure at Shuang Liu Airport.
