【摘要】 本文概述了美国联邦航空局对INM模型的精度要求,并主要从气象条件、飞行剖面的选择和调整、反推力的设置及地形高差等四个方面分析了INM模型预测飞机噪声产生误差的原因及影响大小。从已运行机场现状飞机噪声监测结果和INM模型预测结果对比分析的角度进一步说明了影响INM模型预测精度的主要因素,为机场建设项目环境影响评价中的飞机噪声预测分析提供参考。为保证飞机噪声预测的准确性,本论文给出了INM模型预测飞机噪声时应当着重注意的几个方面。更多还原

【Abstract】 This paper outlines the accuracy requirements of the FAA for the INM model, and analyzes the causes of the error in the prediction of aircraft noise from four aspects:meteorological conditions, flight profile selection and adjustment, reverse thrust setting and terrain height difference. From the perspective of contrastive analysis of aircraft noise monitoring results and INM model prediction results of existing airports, the main factors affecting the prediction accuracy of INM model are further explained, providing references for aircraft noise prediction and analysis in the environmental impact assessment of airport construction projects. In order to ensure the accuracy of aircraft noise prediction, this paper gives several aspects that should be paid attention to when INM model is used to predict aircraft noise.更多还原
