【摘要】：降低机场航空噪声是促进机场发展的重要因素,随着基于性能的导航(PBN)实施的推进,这一新的导航方式为降噪提供了新方法。航空噪声是人的声量感受,机场周围人口较为集中的学校、医院、居民区等构成了航空噪声敏感点,进近航线避开这些噪声敏感点可以达到降噪的效果。根据飞机性能和飞行程序特点,通过确定飞机空间位置,构建了飞行架次-推力-距离(N-F-d)进近航线噪声敏感点规避计算模型;并进行噪声计算模型修正。选取LWECPN为噪声评价量,结合INM噪声评价软件对广州白云机场进行了降噪分析。分析结果表明,噪声敏感点的噪声值显著减小,噪声等值线的影响范围也明显缩小,降噪效果较好。
[Abstract]:Reducing airfield noise is an important factor to promote the development of the airport. With the implementation of the performance based navigation (PBN) implementation, this new navigation mode provides a new method for noise reduction. Avoiding these noise sensitive points can achieve the effect of noise reduction. According to the characteristics of aircraft performance and flight program, by determining the space position of the aircraft, the calculation model of the flight overhead thrust distance (N-F-d) approaching route noise sensitive point is constructed, and the noise calculation model is repaired. LWECPN is selected as the noise evaluation and combined with the INM noise evaluation. The analysis results show that the noise value of the noise sensitive point is significantly reduced, and the influence range of the noise ISO line is obviously narrowed, and the effect of noise reduction is better.
