Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0043] like Figure 1-5 As shown, the present invention provides a two-dimensional airfoil wind tunnel test bench, which includes: a base 110, two partitions 121 and 122, a cover plate 130, a brace bracket 140, and a rod balance 150 , the angle adjustment structure 160 and the wind speed sensor 170.
[0044] The base 110 is horizontally and fixedly installed on the floor of the wind tunnel test section, and the base 110 includes a base body and two slopes 111 arranged at the longitudinal ends of the base body; the upper surface of the base body is higher than the floor, and the base body passes through the slopes 111 It forms a transition with the floor; the borders at both ends of the main body of the base are flush with the borders of the partitions on the same side.
