介绍了2.4m跨声速风洞性能调试研究结果,并作了简要分析。研究结果表明,该风洞流场品质全面达到国军标指标,部分达到当今世界先进水平。该研究首次在国内四壁均为斜孔壁的大型跨声速风洞中解决了优化开闭比、加速区分布形式以及特大驻室M数参考点位置确定等一系列技术问题,表明我国大型跨声速风洞流场性能调试研究取得新进展。
Introduced 2.4m transonic wind tunnel performance tuning research results, and made a brief analysis. The research results show that the quality of the flow field of the wind tunnel fully meets the targets of the national military standard and partly reaches the advanced world level today. The research solves a series of technical problems, such as optimizing the opening / closing ratio, the distribution pattern of acceleration zones and the determination of the reference position of extra large chamber M, in the large transonic wind tunnel with four walls in the country. New progress has been made in the research on the flow field performance tuning of the wind tunnel.
