为深入分析航空器噪声对机场周边地面和空间的影响,基于BADA模型构建了航空器航迹预测模型,基于NPD数据库构建了机场噪声评估模型,对模型进行理论分析与数值仿真,以广州白云机场GYA进场点为例开展了机场噪声影响实例研究,从地面影响、空间影响、影响时间等维度量化了CDA程序的减噪效果.研究结果表明:与IAP程序相比,CDA程序减噪效果明显,且减噪效果随着噪声等级的提高而提高;CDA程序较IAP程序减噪的原因是较低的飞行推力和较高的飞行高度.%To investigate the influence of aircraft noise on the ground and space, the aircraft trajectory prediction model based on BADA model was established and airport noise evaluation model was formulated based on NPD database. Theoretical analysis and numerical simulation were provided to study the influence of airport noise and quantify the CDA procedure noise abatement effect from the view of ground influence, space influence, influ-ence time based on GYA arrival point of Guangzhou Baiyun International Airport. The results show that com-pared with the IAP procedure, the CDA procedure has a more significant effect on noise abatement, especially with the increase of the noise level, which results from lower thrust and higher flight altitude.
