中文摘要：

为了促进我国民航业的节能减排,提高飞机运行的燃油经济性和环保性,考虑实际气象条件,提出了飞机的燃油消耗量和污染物排放量计算模型.结合飞机性能数据,采用BADA模型仿真,开展了飞机进近阶段的节能减排研究.以广州白云机场B767-300飞机GYA方向进场过程为例,利用MATLAB编程计算飞机分别采用梯级进近和持续下降进近飞行的油耗与排放情况,结果表明,持续下降进近可节约超过1/4的燃油消耗量,节能效果显著;持续下降进近可以有效减少HC,CO,NOx,CO2和SO2五种污染物的排放量,且对NOx减排效果最佳.推广持续下降进近的应用有助于实现我国民航的节能减排.

英文摘要：

In order to promote the energy-saving and emission-reduction in China＇s civil aviation and improve the fuel economy and environmental protection of aircraft operation, the fuel consumption model and pollutants emission model are presented according to the actual weather conditions. Com- bined with the aircraft performance data and based on the BADA simulation model, the research on aircraft energy-saving and emission-reduction in approach stage is conducted. Using the example of GYA arrival point of Guangzhou-Baiyun airport and B767-300 aircraft, a MATLAB programming software is used to estimate the fuel consumption and pollutants emission by step-down approach and Continuous Descent Approach, respectively. The results show that： compared with the step-down ap- proach, the Continuous Descent Approach can save over a quarter of the fuel consumption per flight and it has significant energy-saving effect; Continuous Descent Approach also has different emission- reduction effect on five pollutants including HC, CO, NOx, CO2 and SO2, and the effect for NOx is more significant. The promotion of Continuous Descent Approach is found to be helpful to reaching the objective of energy-saving and emission-reduction in China＇s civil aviation.
