The present invention relates to a sensing mechanism of a two-dimensional airfoil model. The sensing mechanism comprises pressure sensor groups, multiple first tubes, the second tube, and a cavity. The pressure sensor groups are vertically fixed to mounting holes in the surface of the two-dimensional airfoil model. The pressure measurement surface of each pressure sensor in the pressure sensor groups is parallel to the surface of the two-dimensional airfoil model. Multiple mounting holes are opened in and vertical to the surface of the two-dimensional airfoil model. The cavity is fixed to the interior of the two-dimensional airfoil model. The reference pressure end of each pressure sensor in the pressure sensor groups is connected to the cavity through the first tube, and the multiple pressure sensors of the pressure sensor groups are in one-to-one correspondence with the multiple first tubes. The cavity is connected with the first end of the second tube. The second end of the second tube is located in the air outside the two-dimensional airfoil model. The present invention can improve the measurement accuracy of surface pressure distribution of the two-dimensional airfoil model. 9 1 2 5 6 8 7310 1
