摘要
随着航空飞机的国产化,飞机发动机噪声问题备受关注.短舱噪声不仅会影响乘客的飞行体验,还会给正常飞行带来安全隐患,因此,解决短舱降噪问题刻不容缓.首先,整理了国内外短舱降噪研究的基本工作和现状,介绍了短舱管道内声传播的理论依据.其次,结合了管道内声传播的计算和实验,列举了国内外利用软件进行模拟仿真的实例.最后,提出了对该领域未来研究方向的展望,以期为相关研究提供经验指导.
Abstract
With the localization of aviation aircraft,the problem of aircraft engine noise has gradually attracted people's attention.Short cabin noise not only affects passengers' flying experience,but also poses safety hazards to normal flight.Therefore,it is urgent to solve the problem of short cabin noise reduction.Firstly,the basic work and current status of noise reduction research on short cabins at home and abroad were summarized,and the theoretical basis for sound propagation in short cabin pipelines was introduced.Secondly,combining the calculation and experiment of sound propagation inside pipelines,examples of simulation using software at home and abroad were listed.Finally,prospects for future research directions in this field were proposed in order to provide empirical guidance for related research.
