基于减噪飞行程序设计的机场噪声敏感区优化仿真

随着我国民航的迅猛发展,机场规模不断扩大,机型不断增多,起降架次持续增多,机场周边的噪声污染日益严重,亟需得到有效控制。通过改进飞行程序改善噪声污染,因其方案制定周期短,应用型强,得到广泛认可。本文通过减噪进离场飞行程序设计,对噪声敏感区进行优化,使用AEDT进行仿真,分别给出了单机型噪声优化与机场整体优化结果,显示用近端减噪离场爬升程序(NADP1)设计、离场偏置、连续下降进近程序(CDA)可以达到明显优化效果。

With the rapid development of civil aviation in China,the scale of the airport has been continuously expanded,the number of aircraft has been increasing,the number of movements has continued to increase,and the noise pollution around the airport has become increasingly serious and needs to be effectively controlled.Improving noise pollution through improved flight procedures is widely recognized due to its short programming cycle and strong application.In this paper,the noise-sensing area is optimized by the noise reduction flight procedures design,Simulate with AEDT,the single aircraft noise optimization and airport overall optimization results are given respectively.The results show that the near-end noise reduction departure climbing procedures(NADP1)、departure deviation,continuous descent approach(CDA)can achieve significant optimization.
