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.

What are advantages of wind tunnel testing?
more money
What makes wind tunnel testing different from testing during an actual flight?
Without wind tunnel testing and other testing, testing in flight would be even more dangerous to the test pilot, and anyone killed should the aeroplane crash.
What is the purpose of testing shapes in a wind tunnel?
the purpose is they can find the best shape to go with the wind
What makes wind tunnel testing different from testing during actual flight?
In a wind tunnel test the plane never leaves the ground. It's only to see how the wind will affect the plane. When your testing during real flight, your actually in the sky and really flying the plane.

Who developed the wind tunnel?
The wind tunnel was developed by the American engineer and inventor Frederick W. Lanchester in the early 1900s. He is credited with creating the first closed-circuit wind tunnel in 1907, which allowed for more controlled and accurate aerodynamic testing. Lanchester's work laid the foundation for modern aerodynamics and contributed significantly to the field of aviation and fluid dynamics.
What are wind tunnels and why do designers use them?
A subsonic wind tunnel is a wind tunnel that cannot take testing to Mach 1 (the speed of sound). There are a wide variety of wind tunnels, and they come in a broad range of sizes, too. They span models from ones that test motorcycle helmets to ones that test a whole small aircraft or aircraft model. A link is provided to the Wikipedia article on the wind tunnel, and you'll find that link below.
Where are some locations of well known wind tunnels?
Well-known wind tunnels can be found at several prominent locations, including NASA's Langley Research Center in Virginia, which has a variety of facilities for aerodynamic testing. The University of Maryland's Glenn L. Martin Wind Tunnel is another significant site, known for its extensive research in aerodynamics. Additionally, the National Wind Tunnel Facility in the UK, located at the University of Southampton, is recognized for its contributions to aerospace and automotive research. Lastly, the large-scale wind tunnel at the German Aerospace Center (DLR) in Göttingen is notable for its advanced testing capabilities in aerodynamics.
