基于噪声最优航迹的飞行程序优化方法研究

Flight Procedure Optimization Method Based on the Noise Optimal Flight Track

机场建设促进了周边地区的经济发展,同时不可避免的带来了航空噪声。为有效控制航空噪声,基于不同飞行程序将航迹进行聚类分析,提出飞行程序的噪声最优航迹的概念。以噪声最优航迹为指导优化飞行程序,使航班执行优化后的飞行程序能避免飞过人口稠密区,从而降低航空噪声影响。以首都机场为例进行实验验证,将优化后的飞行程序导入INM(Integrated Noise Model)中,计算噪声敏感区的噪声值以及不同噪声区间内的人口和面积,并绘制噪声等值线图。实验表明,所提出的基于噪声最优航迹的飞行程序优化方法具有可行性,能有效降低航空噪声影响,可为减噪飞行程序设计提供理论依据。

construction promotes the economic development of the surrounding areas and inevitably brings about the aviation noise. In order to control the aviation noise effectively, flight tracks based on different flight procedures are clustered in this paper, and then the concept of the optimal track of the noise is proposed. The noise optimal flight track is treated as a guide to optimize the flight procedures,so that the optimized flights can avoid flying over a populated area and reduce aircraft noise impact. The Beijing capital international airport is taken as an example to verify the proposed method. Once the optimized flight procedure is input into the INM（Integrated Noise Model） system, the noise value, population and area in different noise region of the noise sensitive area could be calculated and the noise contour map could be drawn Experi-mental results show that the flight procedure optimization method based on the noise optimal flight track is feasible and can effectively reduce the impact of aviation noise. The proposed method has valuable theoretical reference for noise abatement procedures.
