| With the rapid development of civil aviation transportation industry,environmental problem caused by aircraft operation such as air pollution,noise pollution and greenhouse effect are increasingly becoming more serious,and has become a focus problem in the world.Due to the long distance and high altitude of the flight,the environment impact has an amplification effect.Hence,safe,efficient and environment-friendly air traffic operation strategy is a key to keeping the sustainable development of air transportation.This dissertation takes environmental protection as core,builds the aircraft trajectory optimization method based on reduce greenhouse effect so that can give the guide to choose the flight level.Firstly,on the basis of research both at home and abroad,the dissertation qualitative analyzes the impact of upper air flight on environment,and proposed the corresponding mitigation measures.Secondly,analyze the forming principle and environmental impact of the mechanism of CO2 emission and contrail formation,which can cause the greenhouse effect caused by the upper air flight.And then the clustering analysis is used to summarize the temporal and spatial distribution of contrail generation based on the statistics of the meteorological information in the past 30 years in Beijing area.The Absolute Global Temperature Potential（AGTP）is used to establish the scientific and unified metric to convert the CO2 and contrails to global temperature change.Thirdly,taking into account operation characteristics of the single aircraft trajectory,as well as operational rules and meteorological conditions,set up trajectory optimization model with greenhouse effect as the targets.Example verification reveals that the model can effectively reduce the greenhouse effect.Finally,the regional sector flight allocation model with the goal of minimizing the greenhouse effect is established.The example shows that the model can effectively reduce the greenhouse effect and ensure flight safety. |
