Abstract
The utility model relates to a large-scale wind tunnel large stroke axial reciprocating movement measuring device. Currently, an axial static pressure gradient of a test section is measured before a wind tunnel is used, measurement of a pressure-measuring tube is not accurate due to multiple factors and thus flow field calibration results are influenced. Composition of the device comprises the pressure-measuring tube (5) which is installed on an aerofoil profile (6). The aerofoil profile is installed on an aerofoil profile connecting plate (10) which is installed on a supporting base (8). The supporting base is installed on the upper wall (4) of the wind tunnel. A power wire pulley (46) device is installed on the upper wall of the wind tunnel. A bracing wire pulley (20) device is installed on the upper wall of the wind tunnel. The device is used for large-scale wind tunnel large stroke axial reciprocating movement measurement.
