航空器性能对环境运营成本影响分析研究

Research on Impact Analysis of Aircraft Performance on Green Direct Operating Cost

结合航空器运行最关注的两个方面:经济性和环保性,分析航空器性能中对环境运营成本产生影响的因素.为了构建环境运营成本模型,确定巡航高度和速度对CO2排放和凝结尾生成的影响关系.通过AGTP和航空器性能参数构建适用于标准及非标准大气条件下连续的GDOC模型.以北京地区的高空探空数据及A320机型的性能数据为例进行分析.结果表明:优先选择凝结尾产生概率低的高度层飞行,然后尽可能选择较高的飞行高度层,降低飞行速度,可以更好地降低GDOC.

Based on the two most concerned aspects of aircraft operation-economy and environmental protection,this paper analyzed the factors affecting the environmental operation cost in aircraft performance.In order to build a green direct operating cost(GDOC)model,the relationship between cruise altitude and speed on CO2 emissions and condensation tail generation was determined.Then a continuous GDOC model suitable for both standard and non-standard atmospheric conditions was constructed through the Absolute Global Temperature Potential(AGTP)and aircraft performance parameters.Taking the high-altitude sounding data in Beijing area and the performance data of A320 aircraft as examples,the results show that the altitude layer with low probability of condensation end generation should be selected first,and the higher altitude layer may be selected to reduce the flight speed,which can better reduce GDOC.
