摘要
本文研究了通过调节第二喉道截面积来微调风洞实验段马赫数的方法,并给出了其方法的控制参数。实验结果表明,此方法调节时间短、精度高。
We have investigated the method for adjusting Mach number in the subsonic wind tunnel finely and offered data used to control Mach number in this paper. The experimental results show,the method only takes a short time with high accuracy.
