A wind tunnel is an enclosure set up to test the aerodynamic properties of aircraft shapes, vehicle shapes or other things that move through the air. The wind tunnel is generally a big "tube" or sorts, and it is closed on itself. Inside we'll find a large fan, air turbine or the like, and a test chamber where the structure being tested is set up.
With a model, mock-up or the like posted on something to hold it in place, the test personnel leave the chamber, and the machinery that moves the air is started. The moving air rushes past the test shape, and different methods of evaluating airflow across and around the item are used. Wind speeds can (and do!) reach hundreds of miles per hour in many of the tunnels, and safety is an important consideration when operating them.

What is the purpose of a wind tunnel?
A wind tunnel is used to simulate air flow over a model of an airplane or a wing section so it can be studied. The model can be instrumented to measure the lift and drag and other parameters for study. The wind tunnel can produce air flow at the desired speed and condition. Engineers may use a wind tunnel to study and design a wing shape. The Wright Brothers developed the first wind tunnel to design the shape of the wing for their airplane. Wind tunnels can be used to study interference between parts of the aircraft or between an airplane and a bomb as it drops away. There are different types of wind tunnels: low speed wind tunnels, supersonic wind tunnels and hyper-sonic wind tunnels.
What do wind tunnels measure on a airplane wing?
The most valuable measurement within a wind tunnel is pressure, specifically the differential between the upper and lower surfaces of the airfoil as this is the 'engine' that provides lift. This changes as the angle of attack changes, as the airspeed changes, and as the apparent wind direction changes. The wind tunnel lets us observe how the airfoil reacts to different conditions so we can optimize the shape for its intended use.
What was the wright brothers wind tunnel used for?
flying
Is a strong storm that has a wind tunnel a tornado?
No. A tornado is a violently rotating column of air the is in contact with both the ground and the cloud base. Violent winds alone do not make a tornado. A wind tunnel effect simply occurs when buildings or terrain funnel the wind to increase its speed.
What scale is used to measure wind speed?
There are many ways to measure wind, but most common is Beaufort.
What is the name of Large structure used to measure aero dynamic forces of aircraft?
wind tunnel

When was Unitary Plan Wind Tunnel created?
Unitary Plan Wind Tunnel was created in 1955.

What is the Hyundai wind tunnel capable of reaching in wind velocity?
200
How many people can fit in a wind tunnel?
Wind tunnels are different sizes.
How does wind tunnel affect the environment?
It doesn't directly. A wind tunnel is used to detect the airflow over objects such as cars and planes to improve the streamlining.
