摘要

对ARJ客机降落阶段的起落架噪声进行了现场测量分析，为了将起落架噪声源与其他噪声源分开，利用了阵列信号处理技术，实验发现：ARJ飞机起落架噪声主要集中在900Hz以下，且前、主起落架均存在强单音噪声,对起落架噪声可能的声源来源进行了分析，为起落架降噪设计提供了支持。

Abstract

ARJ aircraft landing gear noise spectra and contours were obtained from fly-over measurements.In order to di-stinguish between landing gear and other noise sources array signal processing technology was used, the result shows:A- RJ aircraft landing gear noise is broadband with some single tones,which energy is mainly in 900Hz below.The possible noise sources were analyzed, and hence supporting landing gear noise reducing design.
