Inside the Wind Tunnel: How Aircraft Planes are Tested

WebA wind tunnel is a structure that has air flowing through it — usually in the form of a duct through which the air is set in movement by electric-powered fans (or another mechanism to the same effect). The type and size of wind tunnel used depends on the size of the object undergoing testing, as well as the flow conditions desired.
