| Abstract: | Several methods have been studied in this paper,whichnowadays are being used to control Mach numbers of airflow for dom-estic subsonic and transonic wind tunnel tests.The real situation and theproblems of these methods have been analyzed.A new method of closedloop control to the second throat of the wind tunnel for controlling thestatic pressure in the plenum chamber or the ratio of stagnation press-ure to static pressure has been introduced.The variable coulping proble-ms in the process are emphatically discussed. |
