航班飞行各阶段污染物排放量估算方法

Estimating method of pollution emissions for scheduled flight in different phases

分析了国际民航组织标准排放量模型,推导了各阶段飞行时间、推力、燃油流量等参数的计算公式,以替代ICAO标准排放量模型的飞行时间与燃油流量。考虑了大气环境与飞行参数的影响,给出了各种污染物的排放指数修正模型,以计算各个飞行阶段的排放参数。以B737-800飞机执飞"西安—烟台"航线为例,在空中交通仿真平台上运用Delphi编程计算了航班飞行各阶段的污染物排放量,分析了污染物排放量的变化情况。计算结果表明:CO2与NOx的排放主要集中在航路飞行阶段,CO与HC的排放主要集中在机场滑行阶段,4种污染物排放量从大到小的顺序依次为CO2、NOx、CO与HC,计算结果与相同条件下ICAO参考值相差绝对值不超过1%。

ICAO standard emission model was analyzed.The equations of parameters,such as flight time,thrust,fuel flow and so on,were induced.Flight time and fuel flow could be replaced by the equations in the model.The influence of atmosphere and flight parameters was considered,the calibrated emission index models of various pollutes were introduced,and the emission parameters in different flight phases were calculated.As the flight example of B737-800 from Xi＇an to Yantai,the pollution emissions were calculated by Delphi on VEATE,and the variation rules of pollution emissions were analyzed.The result shows that the emissions of CO2 and NOx mainly appear in cruise phase,and the emissions of CO and HC occur in taxiing phase.The emissions of the four pollutes above are CO2,NOx,CO and HC in the decreasing sequence.The absolute errors between the calculation values and the reference values of ICAO are less than 1%.5 tabs,15 refs.
