飞行航迹对机场噪声的影响分析研究

Influence Analysis of Flight Trajectories on the Airport Noise

不同次飞行产生的航迹各不相同,针对飞行航迹对机场周围噪声的影响分析问题,该文结合航迹数据与噪声监测数据,分别基于T检验和方差分析方法,研究分析相同机型及飞行程序产生的不同航迹对机场周围的噪声影响是否存在显著性差异。基于北京首都国际机场噪声监测系统实际记录数据的实验结果表明,相同飞行程序及飞机机型所产生的不同航迹对机场周围的噪声影响存在显著性差异,通过优化航迹减少噪声影响是可行的噪声控制策略。

The trajectories of different flights are different. With the aspect of analysis of flight trajectories to the influence of airport noise,this paper combines trajectory data and noise monitoring data,opts two ways T-test and analysis of variance,and then researches and analyses if there are significant differences between the noise influence around the airport generated by different trajectories under the same aircraft type and flight procedure. Based on the experimental results with data recorded by noise monitoring system deployed on Beijing Capital International Airport,they prove that there are significant differences between the influence of the noise around the airport,which generated by different trajectories under the same aircraft type and flight procedure. And the strategy by optimizing trajectory to abate the influence of the noise is feasible.
