A2 Wind Tunnel is a full-scale general-purpose open-return wind tunnel located in Mooresville, North Carolina. [1] Created in 2006 by Gary Eaker, the tunnel is able to host a variety of objects including full scale cars, motorcycles, and bicycles.

Portion of the Unitary Plan Wind Tunnel in 2014. Construction of this facility began in 1950-1951 and continued until 1955. Because no one wind tunnel could meet all the demands for additional research facilities simulating the entire range of aircraft and missile flight, NACA chose to build the Ames tunnel with three separate test sections drawing power from a common centralized power plant.
A sample wind tunnel layout showing some typical features including a test section and control room, a machine for pumping air continuously through ducting, and a nozzle for setting the test airspeed. A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". [1]
The cross section of the tunnel is 8.2 feet (2.5 m) high and 8.2 feet (2.5 m) wide. Unlike full-scale wind tunnels, the NTF can adjust airflow to match any model size down to 1/50 scale. The facility can operate at temperatures ranging from -250 ° F to + 150 ° F. [ 1 ] To achieve lower than ambient temperature, liquid nitrogen is sprayed into ...

The tunnel, which will be 18 kilometers (11.1 miles) long, is one of Europe’s largest infrastructure projects, with a construction budget of over 7 billion euros ($7.1 billion).
Results of wind tunnel tests of these models are generally published in the form of nondimensional aerodynamic coefficients (thus being made independent of model size) and made available to the wind-tunnel community, often in review reports containing inter-facility comparisons of data, [5] [8] [9] [10] discussing observed scatter of results ...
