Flight Procedure Optimization Based On Flight Kinetic Model

The pursuit of safety and efficiency of flight procedures are enduring topics in the field of flight procedure optimization.However,with the leap forward both in the quality and quantity of aviation industry,the civil aviation of China has entered a new era of environment-friendly and ECO development,which has put forward further new demands for noise optimization of flight procedures.In this context,the frame model,the flight kinetic model,the aircraft kinematic model and the operating environment model have been analyzed and built,which construct the mathematical model for the trajectory of flight procedure,the implementation and verification of the trajectory simulation for flight procedure under the interface of Simulink have also been conducted.Secondly,the noise assessment parameters suitable for the national environment have been studied and selected.On the basis of the noise data in the aircraft noise performance database and the Savitzky-Golay smoothing method,the MATLAB simulation of noise contours of the aircraft has been implemented.Subsequently,in accordance with the noise optimization procedure published by ICAO,an optimized flight profile is constructed to simulate the noise contour,also analysis and comparisons are made for the optimization methods.Ultimately,an airport flight procedure noise abatement optimization project has been taken as an example,which allows researches for the appropriate noise abatement flight procedures according to the practical situation of the airport.The final results indicate that the scheme effectively reduces the noise impact of the terminal area and meets the flight optimization requirements.The throughout research content contributes ideas to flight procedure safety and economic optimization etc.
