基于EDMS模型的航空器大气污染物的排放计算分析

Emission Calculation and Analysis of Air Pollutants from Aircraft Based on EDMS Model

文章针对航空器运行阶段造成的机场区域环境大气污染现象,阐释了基于飞行计划的航空器污染物排放模型及线源扩散模型计算方法,给出航空器排放大气污染物的减排措施,包括机型组合比例调整、减少航空器地面运行时间、改变下滑角及进近阶段飞行时间,同时应用EDMS模型计算并分析其污染物排放量的变化情况。结果表明,通过使用减排措施,航空器排放的大气污染物均呈减少趋势,验证了减排措施的有效性。

Emissions during aircraft operation will cause the air pollution of the regional environment of the airport.The aircraft pollutant emission model based on the flight plan and the calculation method of the line source diffusion model are clarified.Emission reduction measures of air pollutants include the adjustment of the aircraft type,reducing the aircraft ground operation time,changing the glide angle and the approach flight time.Based on the EDMS model,the changes in pollutant emissions are calculated and analyzed.The results show that air pollutants from the aircraft decrease by using the emission reduction measure,thus verifying its effectiveness.
