Flight Procedure Environment Impact Assessment Method Study

With the rapid development of aviation transportation in our country,people pay more and more attention on the aircraft in flight about the impact to the environment,the main environmental problem research is en-route at home and abroad,few research on the terminal area during flight time,so this paper, mainly study the environmental impact of the flight procedure operation.In this paper, the main research content and innovation are as follows.Firstly,based on the analysis of the characteristics of flight track program,from the four aspects to establish the operation simulation of flight procedure such as flight procedure data module, flight procedure environment module, aircraft force module and aircraft movement module;Then use Matlab and Simulink for each module of the simulation compiler.Secondly, analysis the evaluation model of main noise at domestic and overseas,select a suitable amount of noise evaluation of flight program,and on the basis of noise- the European air traffic control recommended aircraft noise in database ANP2.0 thrust range characteristic curve, and calculate its interpolation;Correction of the assessment of noise have been selected for velocity, attenuation, turning flight, engine thrust, the wind effects;Then raise the evaluation method of flight procedure operation noise,and then simulate and analysis it using Matlab,get the contour map of flight procedure operation noise.Finally, based on the pollutant emission models which is recommended by the international civil aviation organization.Combine with the change of thrust and fuel flow caused by the change of weather conditions.Realizing the improvement of the basis emission model;In addition, correction of speed and height based on the diffusion model of vehicle pollutants,establish the model of aircraft exhaust pollutant diffusion,raise exhausting evaluation method of flight procedures operation, and then simulate and analysis it using Matlab,getting the flight procedure operation pollutant distribution map.
