摘要

摘要: 针对某推力螺旋桨开展了噪声测试,获得了定桨矩角、不同转速工况的螺旋桨噪声频谱特性和典型工况下的螺旋桨噪声辐射指向性,分析了螺旋桨噪声与转速、桨矩角的变化规律,以及螺旋桨的纯音噪声、宽频噪声和总噪声的辐射指向性。结果表明:随桨矩角和转速增大,宽频噪声在总噪声中占比增大,在大桨矩角、高转速下,宽频噪声强度已经与纯音噪声相当。宽频噪声辐射指向性与螺旋桨桨叶自噪声相符。

Abstract: The noise of a pusher-propeller was tested. The noise frequency spectrum characteristics of propeller at different revolution speeds with fixed pitch were obtained to research the noise level varying with revolution speed and pitch. The directivity characteristics at typical operating condition were also tested to get the directivity of tone noise, broadband noise and overall noise. The results showed that as the revolution speed and pitch increased, the contribution of broadband noise to overall noise increased. The broadband noise was comparable with the tone noise at large pitch and high revolution speed. The directivity of broadband noise agreed with the characteristics of blade self-noise. It is probable that the broadband noise is dominated by blade self-noise.
