| 中文摘要: |
| 在全消声室配套射流噪声试验台是开展射流噪声机理和测量方法研究的重要基础。本文详细介绍了基于中压气源的亚/跨音速射流噪声试验台的设计指标分析、系统软硬件组成、调试以及达到的效果等。结果表明,采用两级调压的方式可以较好的满足射流噪声研究所需的流量和压力需求,同时通过合理的流道设计,控制精度和流场品质均达到较高要求,为亚/跨音速射流噪声研究提供了重要支撑。 |
| 英文摘要: |
| In order to develop the research on the jet-noise mechanism and the measuring method, the building of the test equipment in anechoic chamber is necessary. This paper introduces the design index, system composition,debugging and the effect of the jet noise test equipment based on the medium-pressure air system in detail. The test result showed that two stage pressure regulator could meet the jet noise test demand of the air flowrate and pressure. It’s a effective support for the research on the subsonic/transonic speeds jet noise. |
