Developer of Air Conditioning Helped Chill NASA Wind Tunnels

Worldwide stress were high in the fall of 1941 as U-boats bothered ships in the Atlantic and German forces pressed deep into the Soviet Union. There was an important requirement for the United States to get the National Advisory Committee for Aeronautics (NACA)’s brand-new engine lab (today, NASA’s Glenn Research Center) in operation as quickly as possible. It was particularly crucial to finish its Elevation Wind Tunnel (AWT)which might be utilized to enhance the engine efficiency of high-altitude fight airplane.

NACA engineers were professionals in wind tunnel style, however imitating 30,000-foot elevations to check full-sized engines in the brand-new center postured a number of special difficulties Maybe the most overwhelming was cooling the countless cubic feet of air flow in the tunnel to -47 degrees Fahrenheit. The NACA’s efforts to develop sufficient cooling coils for the extraordinary system showed useless. To accelerate the style procedure, the NACA persuaded Willis Carrier, the country’s premier refrigeration authority, to create the cooling system for the enormous tunnel.
