摘要
在大量查阅国内外相关技术文献的基础上,对风洞声学试验技术的发展历程进行了分析与总结,并对目前试验的两大关键技术领域——声学风洞与麦克风相阵列作了比较详细的介绍与讨论。通过对国内外气动噪声试验技术状况的调查研究,充分阐释了目前中国发展该项技术的必要性和迫切性,并提出了相应的建议。
The techniques in wind aeroacoustic measurement lications In addition, the two elementary factors of the aeroacoustic measurement, acoustic wind tunnel and microphone phased array, were introduced and discussed in detail. The authors explained the necessity and stringency of the developing techniques in China on basis of investigation to the status of aeroacoustic measurement techniques inside and outside the country.
