摘要
为更加精确地计算机场起降循环颗粒物排放量,文章在国际民航组织提出的一阶近似方法的基础上,利用实测QAR数据,对燃油流量、工作时间以及非挥发性颗粒物排放指数进行修正;运用P3-T3方法,对挥发性有机颗粒物排放指数进行修正。以GE90-115B型发动机历史QAR数据为基础,计算某次飞行起降循环的颗粒物排放量。分析结果表明,相比一阶近似方法,修正方法能够更加准确地量化起降循环颗粒物排放对机场大气环境的影响,为机场的节能减排工作提供参考。
In order to accurately calculate the particulate matter emissions in aero-engine landing and take-off cycle, based on the first-order approximation method proposed by ICAO, the measured QAR data is used to correct the fuel flow, working time and non-volatile particulate matter emission index;and the P3-T3 method is used to correct the volatile organic matter emission index. Based on the historical QAR data of the GE90-115B engine, the particulate matter emissions of a flight landing and take-off cycle are calculated. The analysis results show that compared with the first-order approximation method,the correction method can more accurately quantify the impact of landing and take-off cycle particulate matter emissions on the airport atmospheric environment, and provide reference for the airport energy conservation and emission reduction.
