摘　　要：为综合考虑飞机运行的经济性和对环境的影响,首先基于国际民航组织的基准排放数据建立飞机污染物排放量计算模型,提出排放价格指数概念并建立考虑排放因素的综合飞行成本计算模型;随后分别建立基于传统飞行成本和综合飞行成本的爬升参数优化模型,并分析爬升表速和推力对排放成本的影响;然后基于遗传算法建立“表速-推力”组合优化模型,并以某型宽体飞机为例进行优化计算;最后对优化参数的影响因素和污染物排放价格指数的影响进行分析。结果表明:飞行速度和推力对飞行成本有直接影响,适当减小可以有效降低飞行过程中的综合飞行成本;与传统优化方式相比,文中模型可以降低2.8%的排放成本、0.34%的综合飞行成本。To comprehensively consider the economy of aircraft operation and its impact on the environment,analyze the total flight cost of time cost,fuel cost,and emission cost in the climbing process,a calculation model of aircraft pollutant emissions was established based on international civil aviation organization(ICAO)reference emission data.Then the concept of emission price index was put forward,and an integrated flight cost calculation model considering emission factors was established.Secondly,the climb speed optimization models based on traditional flight cost and integrated flight cost were established respectively.Then,the influence of the indicated speed and thrust rank on flight cost was analyzed.Thirdly,a combined optimization model of‘climb indicated speed and thrust’was established based on the genetic algorithm,and a wide-body aircraft is taken as an example to calculate the optimal‘indicated speed and thrust’combination under certain conditions.Finally,the influencing factors of optimization parameters and the influence of pollutant emission price index were analyzed.The results show that the optimal speed and thrust rank increases with the increase of weight;with the increase of temperature deviation,the optimal thrust rank continues to increase while the optimal speed first increases and then decreases;with the increase of cost index C_(1),the optimal thrust remains unchanged and the optimal indicated speed continues to increase.Based on the research of the combined optimization model of‘climb indicated speed and thrust’,we can get the conclusion that a proper decrease in the flight speed and thrust can effectively reduce the integrated flight cost during flight.Compared with the traditional optimization method,the model in this paper can reduce the integrated flight cost by 0.34%and emission cost by 2.8%.Besides,with the increase of emission price index I(NO_(x)),the proportion of emission cost increases,the optimal indicated speed and thrust level show a decreasing trend,and reducing the
