  • In the 0.6m×0.6m continuous transonic wind tunnel of CARDC, experiments for center-line probes with different arrangements of orifices, different length and different installation sites were conducted. Results indicated that, the Mach number fluctuation tested with the center-line probe of symmetry orifices was weaker than that of staggered orifices. And when the experiment Mach number was below 1.0, the experiment result of short center-line probe agreed well with the long probe. But when the experiment Mach number was higher than 1.0, the Mach number fluctuated severely due to the nose cone of the short probe. And when the experiment Mach number was below 1.0, the machining quality of orifices along the center-line probe had a great influence on the test results.
