民用飞机LTO阶段精细化排放清单技术

With the rapid development of aviation industry in China, air pollutant emission has increased sharply. The aircraft in the airport area operates at a low flight altitude, making a big difference to the air quality and the residents health in the surrounding area. However, it is difficult to implement effective environmental management of the civil aviation transportation industry currently without clear pollution emission characteristics of aircraft engines and key emission factor data. .This project aims to study the issue of aircraft engine emission in the landing and take-off cycle (LTO cycle) in the airport area. The main contents include five parts: (1)Identifying operating condition and characteristics, and collecting basic emission data of aircraft engine during LTO cycle. (2)Study on LTO cycle emission factor calculation model based on “measurement and simulation”. (3)The establishment of LTO cycle emission factor database for main civil aircraft types in China. (4)Study on refined emission inventory of aircraft in LTO cycle based on dynamic flight flow. (5)Demonstration study on refined emission inventory of aircraft in typical airfield in LTO cycle..The research results of the project can provide important technical support and scientific basis for environmental management of civil aviation, improvement of urban air quality, promotion of energy conservation and emission reduction and rational airport planning layout.

随着我国航空业的快速发展，污染物排放量急剧增加。机场区域运行的飞机飞行高度低，对空气质量和周围居民健康具有显著影响。但当前对飞机发动机的污染排放特征尚不明确，缺少关键排放因子数据，难以对民航运输业实施有效环境管理。.本项目拟针对机场区域飞机起降过程中，发动机污染排放问题进行研究，主要内容包括（1）飞机LTO运行工况识别及污染排放特征研究，获得多机型基础排放数据；（2）基于“实测和模拟”相结合的飞机LTO排放因子计算模型；（3）适用于我国的民用飞机主要机型LTO排放因子数据库；（4）基于动态航班流的飞机LTO精细化排放清单技术；（5）典型机场飞机LTO精细化排放清单示范研究。.项目研究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，提供重要技术支撑和科学依据。

随着我国航空业的快速发展，污染物排放量急剧增加。机场起降运行的飞机飞行高度低，对周边空气质量和居民健康具有显著影响。准确可靠的源清单是确定机场污染物排放对周边空气质量影响的基础和关键，但目前研究中大多使用了通用的排放参数和排放因子，未考虑机场实际条件的影响。本项目通过对机场气候和运行条件的分析，提出了飞机排放参数修正模型，构建了我国各机场本地化排放因子数据库。基于活动水平数据建立了2019年我国机场飞机起降排放清单，研究了清单的时空特征和机型/飞行阶段贡献率。通过测试研究了典型机型PM和TVOC的排放特征及排放因子。本项目研究成果将有助于探索机场排放对城市和区域尺度空气质量的影响，提高空气质量模型的模拟精度和减排措施的有效性，为精准治污提供支持。
