Gusts can cause variations in the test section dynamic pressure, and in the distribution of dynamic pressure across the test section . 阵风会使试验段动压和试验段截面动压分布发生变化。
For the velocity survey the pitot-static tube is moved around the jet, and the dynamic pressure is measured at numerous stations . 为了测量速度,可把皮托静压管放在试验段内各个地方并测量多点上的动压。
