减推力起飞对环境的影响

Effect on environment of reduced thrust takeoff

为研究减推力起飞对环境的影响,包括其对噪声排放的影响和对二氧化碳以及氮氧化物等主要大气污染物排放的影响,本研究使用对照试验的方法,通过不同型号民用客机设置对照组,根据对照试验的结果进行处理分析,以分析减推力起飞对于环境的影响。通过分析可以得出,减推力起飞造成近距离噪声小幅升高,并伴有氮氧化物排放量降低,而对于二氧化碳的排放量几乎没有影响。

The purpose of this paper is to study the reduced thrust takeoff impact on the environment, including noise emissions and the impact of carbon dioxide and nitrogen oxides emissions of air pollutants. This study uses the method of controlled trials. We set different types of civil aircraft in the control group, and then analysis the results of the controlled trials to analyze the reduced thrust takeoff impact on the environment. It can he drawn by analyzing that the reduced thrust takeoff caused the close noise increased slightly and together bring a fall to the emissions of NOx , but it nearly have no impact on CO2 emissions.
