摘　　要：以气动中心0.6m×0.6m连续式跨超声速风洞为试验平台,开展了轴探管不同开孔型式、不同长度及不同安装方位对测试结果的影响研究。测试结果表明:对称开孔型式轴探管测量结果普遍优于交错开孔型式;当试验马赫数小于1.0时,短轴探管测试结果与长轴探管相当,但当试验马赫数不小于1.0时,短轴探管头锥对测试结果影响较大;当试验马赫数小于1.0时,轴探管测孔加工质量的一致性对测试结果有显著影响。In the 0.6 m×0.6 mcontinuous 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.
