摘要

为深入研究不同类型短轴探管的测值特性，设计了多种无需张线固定的短轴探管，通过风洞试验开展了相关探索研究。试验结果表明：不同外形参数的短轴探管与长轴探管在马赫数在0.95以下时马赫数方均根偏差量差异不超过0.000 3，马赫数修正量差异不超过0.000 8，测值曲线无明显变化；马赫数在1.0~1.4区间时，不同形式的短轴探管与长轴探管的测试结果存在明显差异，优化短轴探管头部外形参数、增加柱段长度可不同程度地降低头部对试验段流场的干扰。

Abstract

Several types of short centerline probes were designed without need of cable fixation.The characteristics of the measured values were studied by wind tunnel test.The results showed that the difference of Mach number root⁃mean⁃square deviation between short centerline probe and long centerline probe with different shape parameters was less than 0.000 3，the difference of Mach number correction was less than 0.000 8，and the measurement curve had no obvious change when the Mach number was below 0.95；There were great differences between short centerline probe and long centerline probe of different shape parameters When the Mach number was between 1.0 and 1.4，changing the shape parameters of short centerline probe or increasing probe length can reduce the interference of head to flow field to some extent.
