Probe that nearly wall region of measuring tank wall flows supports and moves survey device

The utility model discloses a probe that nearly wall region of measuring tank wall flows supports and moves survey device, aim at solves the current situation that lacks the nearly wall region blending measuring means of transonic wind tunnel cell wall at present. It includes that survey the control unit is moved to probe support element, the flow direction, the normal direction is moved and is surveyed the control unit. Probe support element forms the probe mounting hole including fixed lid and nosed two parts at the nosed. The utility model discloses can obtain the distribution characteristic of the mobile characteristic quantity in groove through a small amount of experiment train number as early as possible to do benefit to the measurement of the nearly wall region flow field of cell wall, analysis, and cell wall boundary condition's accuracy is verified. Adopt mode in the indoor location, can reduce testing arrangement and to the influence of test section primary air, guarantee the groove and flow the ac
