Wind tunnel is a core equipment in all aerospace and mechanical engineering fields. This subsonic wind tunnel is an air testing machine that monitored the behavior of air around different objects.
The tunnel can reach speeds up to 150 km/h and its test section is 40*40*60 cm. The air speed, density, pressure is monitored over computer screen and data can be plotted, along side with the x,y,z forces exerted on the object.
