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.
A wind tunnel.
"Baals wind tunnel" likely refers to a wind tunnel named after renowned aerodynamicist Ludwig Prandtl. Prandtl's work on wind tunnels in the early 20th century was foundational in understanding aerodynamics, and his name is often associated with wind tunnel research and design.
Unitary Plan Wind Tunnel was created in 1955.

Wind tunnels are different sizes.
Frank wenham invented the first wind tunnel in 1871 in Greenwich England with his colleague John Browning
Wind Tunnel with Dave Despain - 2003 was released on: USA: 21 February 2003
It doesn't directly. A wind tunnel is used to detect the airflow over objects such as cars and planes to improve the streamlining.
