基于绿色飞行的航空器离场累积事件噪声控制研究

航空业的迅猛发展,在带来巨大经济、社会效益的同时,也造成日益严重的噪声污染.为缓解机场周边噪声问题,贯彻"绿色飞行"理念,本文从飞行程序优化和飞行架次调整两方面进行航空器离场噪声控制研究.采用计权等效连续感觉噪声级为评价指标,应用累积事件噪声计算模型,以广州白云机场为例,绘制噪声等值线图,计算噪声影响面积,分析噪声控制效果及原因.结果表明,CCO减噪程序和飞行架次调整两种方法均可有效减少噪声影响面积,但噪声控制方法各有利弊,实践过程中应扬长避短灵活运用.

Noise Abatement of Cumulative Departure Flights Based on‘Green Flight’

With the quick development of aviation industry, economy grows fast but the noise pollution is increasingly severe. To solve the noise problem around the airport and implement the concept of‘Green Flight’development, the research of departure procedure noise control is carried out in terms of noise reduction procedure and flight adjustment. To calculate noise area and draw the noise counters, Weighted Equivalent Continuous Perceive Noise Level is chosen as evaluation parameter and cumulative event noise evaluation model is applied. Results show that: two kinds of the noise control methods can reduce noise value both, but different noise control methods have their virtues and their faults; we should apply flexibly and avoid weakness in practice.
