Noise Abatement of Continuous Climb Operation Based on BADA

随着中国民航业的快速发展,机场周边噪声污染不断加剧,改进飞行程序来缓解噪声影响因其研究周期短、应用性强等特点,成为当前研究热点.本文概述了CCO的定义、特点,分析其飞行剖面,简述了基于BADA的航空器性能模型和机场噪声评估模型;并以广州白云机场VIBOS离场方向为例,运用MATLAB编程计算噪声并绘制噪声等值线图,从噪声影响时间、面积及区域形状等方面对比传统离场程序和CCO离场程序的噪声影响效果.结果表明:CCO离场程序可有效减少噪声影响时间,且在高噪声等级下降噪效果更佳;CCO离场程序可有效减少噪声影响面积;CCO离场程序可改变噪声等值线形状.

With the rapid development of China＇s civil aviation, noise pollution around the airport is growing. Low noise flight program is an advanced research hotspot because it is easier to develop and apply to practice. In this paper, the definition, characteristic and flight profile of CCO are summarized, and BADA-based trajectory prediction model and airport noise evaluation model are analyzed as well. The departure procedure in Guangzhou Baiyun International Airport is chosen to provide basic date to calculate noise level and draw the noise counters with help of MATLAB. The noise effects of traditional procedure and CCO-based procedure are compared from noise area, noise influence time and noise region shape. Compared with traditional procedure, the CCO-based procedure can reduce the noise influence time, especially in the high noise level. At the same time, the CCO-based procedure can effectively reduce the noise area and affect the noise region shape.
