| This thesis focuses on approach track optimization with point fusion technology.Combined with the operation environment,technical characteristics,atmospheric model and aircraft motion state model of point fusion program,approach track optimization research based on point fusion technology is carried out.Firstly,this thesis studies point fusion technology at home and abroad,analyzes the concept of point fusion technology and navigation facilities required by the technology,airworthiness performance of aircraft,operation characteristics of terminal area entry and departure procedures,and operation requirements of air traffic controllers and aircraft pilots when running point fusion procedures.Then,the kinematics model,fuel consumption model and descent profile of the aircraft are analyzed according to the atmospheric model and the force situation of the aircraft in the descent process.At the same time,a VISUAL GUI interface of aircraft descent profile is designed.Then,according to the operation characteristics of the point fusion program and the aircraft motion state model proposed in Chapter 3,the optimization strategy of the point fusion approach program is proposed with the goal of economy,efficiency and environmental protection.The multiobjective optimization function of the point fusion approach program is constructed and the model is solved by genetic algorithm.Finally,combined with the optimized descent profile,the capacity of the point fusion program of Zhengzhou Xinzheng Airport is evaluated.The network maximum flow mathematical model and SIMMOD software are respectively used to simulate the optimized point fusion program,and the influence of the optimized point fusion program on the airspace capacity of the approach section of Zhengzhou Xinzheng Airport is obtained.In the end,the thesis is summarized to highlight the main research results,and at the same time,the future development and the practical application of point fusion system are prospected. |
