A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunne
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.
The effect of streamlining is made visible in a wind tunnel. Shaping the body to make it more streamlined reduces fuel consumption.

…7 feet (2.1 m) in diameter. A 500 hp (370 kW) electric motor drove the paddle type fan blades. In 1931 the NACA built a 30-by-60-foot (9.1 by 18.3 m) full-scale wind tunnel at Langley Research Center in Hampton, Virginia. The tunnel was powered by a pair of fans driven by 4,000 hp (3,000 kW) electric motors. The layout was…
