Airfoil with Manonmeter

thingiverse

A test section module for a wind tunnel is designed to accommodate an NACA 2412 airfoil, which fits snugly within an 8"x8" test section. The wing features openings that are connected via 1/16" ID - 1/8" OD clear polyurethane hose to a custom-built manometer. The barbed hose connections come from McMaster Carr. This setup allows for precise pressure readings along each part of the wing, making it an ideal tool for studying fluid dynamics. By adjusting the angle of attack, educators can observe changes in pressure across the wind tunnel's surface. In its absence, a fan with sufficient capacity can be used to replicate the effects of a wind tunnel. The NACA 2412 airfoil can be easily 3D printed, while the manometer can be laser-cut for precision. To create this engaging lesson, educators can focus on fluid dynamics and use the test section module in conjunction with a large fan or wind tunnel. By recording pressure differences across various wing locations, students can gain valuable insights into aerodynamics.
