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。
Aiming at the airport noise prediction problem of large flow and multi-runway systems, a method of predicting airport noise based on flight procedures is proposed. The prediction method is based on ANP database and BADA database to determine the noise distance characteristics of aircraft. Considering the factors of day-night flight times, combination of landing gear type and runway departure proportion, the calculation of day-night equivalent sound level of prediction points and noise-limited Regional identification model. Finally, combined with the traffic flow data of a certain airport, the noise and the noise limited area of the prediction point are analyzed. The results show that this method is feasible and can improve the efficiency of airport noise prediction.
