Estimation Of Airborne Carbon Emissions And Analysis Of Influencing Factors

In the next few years,China's civil aviation industry will maintain rapid development,and the CO2 emissions will continue to increase.On the basis of the dynamic model of carbon emission system,this paper researches the influence factors and calculation methods of carbon emissions in the context of global warming.Firstly,this paper analyzes the main factors of carbon emission,such as the carrying rate,the design capacity,the carbon emissions of aviation fuel,the amount of carbon emissions in the air,the LTO Fuel consumption,large circle distance,and so on,and finally builds the aviation carbon emissions system dynamics model.Then,calculated with the actual voyage of Eastern Airlines and the aircraft model,power system,fuel consumption rate,carrying capacity and other data,the result shows that the fuel consumption per unit displacement and the displacement carbon emissions decrease with the increase of the distance of the route;the farther the distance is,the greater the unit cruise consumption and the less carbon emission per unit passenger;the difference of the amount of LTO fuel consumption between each model is relatively small.The results are compared with those calculated by ICAO.The correlation between fuel consumption calculated by the two methods is quite strong;the fuel consumption calculated by ICAO method is much larger than the fuel consumption calculated by the method in this paper;the passenger carbon emissions of the voyage units calculated by this method are larger than those of the ICAO calculation method.Finally,the future development direction of aviation emission reduction is studied.Some suggestions are put forward to the feasibility of aviation emission reduction:Optimizing the route structure(including optimizing the network structure,and more open up the medium and long-range routes and large aircraft by the implementation of long-distance flight),improving engine drive efficiency,the use of bio-aviation fuel.
