Abstract: A pressure measuring device for a scale model for elastic similar structure of a wing in a large transport plane adopts a bracket for pressure measuring steel pipes formed by 3D printing, shapes of an upper surface and an lower surface of the bracket are completely the same as local airfoile profiles of a skin at required pressure measuring positions, and the upper surface and the lower surface of the bracket are bonded to the skin and wing beams; a pressure measuring hose is connected with the pressure measuring steel pipe, and the pressure measuring steel pipe is embedded into the bracket and fixed to it; the upper surface and the lower surface of the bracket are provided with semi-cylindrical convex structures; and the pressure measuring steel pipe extends out of the pressure measuring hole in the surface of the skin for pressure measuring steel pipe in the bracket.
