    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.
