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。 According to the analysis of flight path data and noise monitoring data, the paper analyzes the influence of flight path on the noise around the airport by using T-test and ANOVA respectively, Whether there is a significant difference between the impact of different tracks generated by flight procedures on the noise around the airport. The experimental results based on the actual recorded data of Beijing Capital International Airport Noise Monitoring System show that there are significant differences in the impact of different tracks generated by the same flight program and aircraft models on the noise around the airport. It is feasible to reduce the impact of noise by optimizing the track Noise control strategy.
