飞机发动机对机场区域大气环境影响评估技术

Air transport increased rapidly in recent years, as well as the aviation emissions. There are kinds of air pollution sources at the airport, like aircrafts, ground support equipments, expressway, and etc. Along with the increase of the number and size of airports in China, it is of important to develop environmental management plan to reduce airport-related emissions, due to the severe haze pollution and the pressure from international community.. In this project, we focus on the air emissions from aircraft engine around the terminal. The detailed work includes: (1) aircraft performance parameters matching model, (2) aircraft LTO cycle air emission inventory estimation method, (3) dispersion model based on 4D trajectory simulation. . Overall, as an integrated technology of aircraft atmospheric environmental impact assessment, the results of the project provide scientific basis for aviation environmental management, local air quality improvement, energy saving and emission reduction, and airport construction planning.

随着航空业的快速发展，污染物排放量急剧增加。机场区域运行的航空器飞行高度低，对空气质量和周围居民健康具有显著影响。当前我国灰霾污染加剧、机场数量和规模的不断扩大、以及来自国际社会对于航空节能减排的压力，都使我国迫切需要对机场实施有效环境管理。.. 本项目拟针对机场区域飞机运行过程中发动机排放带来的大气污染问题进行研究，主要研究内容包括（1）对飞行性能参数匹配模型的研究，实现雷达记录数据中所遗失的飞行性能参数的自动识别与匹配；（2）对真实飞行条件下发动机污染排放指数EI进行研究，建立机场区域飞机发动机污染排放清单估算方法；（3）基于4D飞行轨迹仿真，建立飞机发动机污染扩散耦合模型，并通过现场实验，验证模拟方法有效性。.. 作为一体化的机场区域飞机发动机大气环境影响评估技术，项目成果可为民航环境管理、改善城市空气质量、促进节能减排、合理机场规划布局，提供重要技术支持。
