摘要

对ARJ客机过顶的噪声源进行了现场实验分析。为了将飞机不同噪声源分开,利用了阵列信号处理技术,设计了多臂螺旋阵。实验发现:ARJ飞机的噪声源主要分布在发动机、起落架、襟翼、尾翼后部等位置,不同频率下,主要噪声源的组成不同,为飞机降噪工作提供了支持。

Abstract

ARJ aircraft noise sources were obtained from fly-over measurements.In order to distinguish different noise sources, array signal processing technology was used, and multi-arms spiral array was designed. The result shows that the main noise sources are aero-engine,landing gear,flaps and the back of empennages and the main sources are different with the different frequencies. These can provide the support for noise reduction.
