摘要
应对近年来国际低碳航空发展和航空减排实践的转变,引入灵敏度分析方法改进碳计算器模型,组合机型、LTO循环/巡航操作阶段、航线网络模式等外部性要素,基于单架次航班航迹点实际数据进行了京沪航线碳排放环境损害评估,并基此分析了机型替代后的碳排放环境损害变化。研究结果表明:不同机型间和相同机型内部,分别受机型本身和滑行时长影响致使单架次航班碳排放环境损害存在差异,既表现出大型飞机较高碳排放环境损害的普遍规律,但也有例外。若使用相同机型,中心-辐射航线网络模式的碳排放环境损害较高;若使用不同机型,2类航线网络模式的碳排放环境损害并不确定。基于客流需求的研究发现,飞行频率对航空碳排放环境损害的影响更为关键,采用点对点航线网络模式以大型飞机降低飞行频率能减少绝对碳排放。
In recent years,in order to response the development of international low-carbon aviation and transition practices of emission reduction,sensitivity analysis method is introduced to improve the carbon calculator model.This model combines aircraft type,LTO cycle/cruise operation phase,airline network model and other external factors.Based on actual data of single flight track points,environmental damage of aviation carbon emission is assessed,and changes of environmental damage of aviation carbon emission after aircraft type replacement are analyzed in PEK-SHA.The results show that there are differences between flights’environmental damage of aviation carbon emission,not only between different aircraft types but also within the same aircraft type,caused by the influence of aircraft type itself and the length of taxiing time.There is a universal law that environmental damage of aviation carbon emission for single large aircraft is high,but there are exceptions.If the same aircraft type is used,hub-spoke flights’environmental damage of aviation carbon emission are higher,because of the influence of additional LTO cycle operation phase and additional flight distance of cruise operation phase.If aircraft types are different,environmental damage of aviation carbon emission is uncertain between two types of airline network model,because of the influence of aircraft type itself.Based on passenger flow demand,the study of PEK-SHA is found that the influence of flight frequency for environmental damage of aviation carbon emission is more critical.Using large aircrafts of point-to-point to reduce flight frequency can reduce absolute carbon emission.
