Wind tunnels move air around an object making it react as though it was moving itself. It lets the design team know what changes can be made to increase the effectiveness of their design. Not only is it used for aircraft, it's also used for trains, automobiles and the like.

How did the wright brothers figure out how to fly?
Even though they were not true scientists, only bicycle mechanics, they applied scientific research and built a wind tunnel to test different wing designs and then they built model gliders and tested them before attempting to build a man-powered airplane.
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.
How are aerodynamics tested?
aerodynamics can be tested by a wind tunnel

A wing's theoretical shape is tested during the design phase?
Wing shapes are tested in a wind tunnel to see how they will perform in flight.
What are disadvantages of wind tunnel?
Wind tunnel testing is generally very expensive and time consuming. In addition, if the object to be tested (i.e. a car, an airplane) is too big to fit in the tunnel itself, a very accurate scale model must be produced, and Reynold's numbers (a number describing the flow conditions over the object) must be accurately matched to the expected operating conditions. These models can be prohibitively expensive as well.

Where are the aerodynamic elements of Formula one cars normally tested?
Computer models are used extensively and in a wind tunnel
What did the Wright Brothers do that was so important?
They were the first to fly an airplane successfully. The Wright brothers were not brilliant scientists, however they used scientific test and analysis to develope new designs that allowed the airplane to fly. They built a wind tunnel and measured the forces on their wing designs. They built gliders that were flown like a kit and then gliders that could carry a person. They added an engine to it and were the first person to fly a powered, heavier-than-air aircraft.
What Do You Call Four Blondes In A Row?
A wind tunnel.
When was Unitary Plan Wind Tunnel created?
Unitary Plan Wind Tunnel was created in 1955.
