Wind tunnel | aeronautical engineering | Britannica

Wind tunnel, device for producing a controlled stream of air in order to study the effects of movement through air or resistance to moving air on models of aircraft and other machines and objects. Provided that the airstream is properly controlled, it is immaterial whether the stationary model under testing is designed to move through the air

Wind tunnel definition is a tunnellike passage through which air is blown at a known velocity to investigate air flow around an object (such as an airplane part or model) placed in the passage.

How Wind Tunnels Work | HowStuffWorks

From swaying, unstable breezes to hurricane-force blasts, Mother Earth's wind is a notoriously fickle condition, and thus, pretty much worthless for aerodynamics testing. Wind tunnels, on the other hand, provide a controlled environment for this kind of testing. Wind tunnels are simply hollow tubes; at one end, they have powerful fans that create a flow of air inside the tunnel.

How does a wind tunnel work? Explain that Stuff

May 30, 2020· A wind tunnel is a bit like a huge pipe that wraps around on itself in a circle with a fan in the middle. Switch on the fan and air blows round and round the pipe. Add a little door so you can get in and a test room in the middle and, hey presto, you have a wind tunnel. In practice, it's a bit more sophisticated than that.

Vertical wind tunnel Wikipedia

A vertical wind tunnel (VWT) is a wind tunnel which moves air up in a vertical column. Unlike standard wind tunnels which have test sections that are oriented horizontally, as experienced in level flight, a vertical orientation enables gravity to be countered by drag instead of lift, as experienced in an aircraft spin or by a skydiver at terminal velocity.
