基于飞行程序的机场噪声预测方法

Research of Airport Noise Prediction Method Based on Flight Procedures

针对大流量、多跑道系统的机场噪声预测问题,提出了一种基于飞行程序预测机场噪声的方法。该预测方法依据ANP数据库及BADA数据库确定航空器的噪声距离特性,考虑昼夜飞行架次、起落机型组合、跑道进离场比例因素,依据飞行剖面给出预测点昼夜等效声级计算及噪声受限区域确定模型。最后,结合某机场交通流数据,分析预测点噪声及噪声受限区域。结果表明,该预测方法具有可行性,能够提高机场噪声预测的效率。

In consideration of airport noise prediction problem with large traffic flowand multi-set runways,a method is presented to predict airport noise based on flight procedure. Taking day and night flights,type combination,approach and departure proportion of different runway into consideration,this method presents the calculating models of the daytime and nighttime noise and noise restricted area in according to flight profile,which combines ANP database and BADA database to determine aircraft noise characteristic with distance. Finally,forecasting point noise and noise restricted area is analyzed according to airport traffic flowdata. The result shows that the prediction method is feasible,which can improve the efficiency of airport noise prediction.
