NACA

Have you ever wondered about the beginning of one of the most important aeronautical research institution? NACA, stands for: “National Advisory Committee for Aeronautics”, it’s an agency founded on March 3, 1915 in the United States to prioritize aeronautics during World War I.

As we may know Wilbur and Orville Wright have studied aviation in a wind tunnel, and more research related to flight. However, “Langley” a location in USA were the place that gathered many secret researches, Langley was known as an agency and government institution, it was considered to be a relevant place. Langley had studied aviation of bird and established the Langley Aerodrome, unsuccessful manned, tandem wing-configuration powered flying machine.

An advisory committee created by 14 members: two of each from the War and Navy Departments; one each from the Weather Bureau, the Bureau of Standards, and the Smithsonian Institution. All of them familiarized with aeronautical science or related.

The purpose of the committee was “to supervise and direct the scientific study of the problems of flight with a view to their practical solution, and to determine the problems which should be experimentally attacked and to discuss their solution and their application to practical questions.”

Langley research center was the official site and NACA’s oldest field centers, the research center devotes two-thirds of its programs to aeronautics and the rest to space.

The outstanding researches goes from airfoils to high speed tests. The facilities:

  • Langley Memorial Aeronautical Laboratory (Hampton, Virginia), Now NASA
  • Ames Aeronautical Laboratory (Moffett Field)
  • Aircraft Engine Research Laboratory (Lewis Research Center)
  • Muroc Flight Test Unit (Edwards Air Force Base)

NACA developed the famous NACA Airfoils or NACA system, widely used in airplanes and helicopters such as Cessna`s planes and Bell helicopters, among others. Another relevant contribution is related to the area rule, the ideal cross-section area of objects to reach the speed of sound.

NACA and all its personnel was transferred to NASA, when the last was funded. Therefore, NASA inherited all the knowledge gained in NACA. LaRC or NASA Langley researchers use more than 40 wind tunnels with the purpose for improving aircraft and spacecraft technology.

  1. Okay, this is fantastic. That pic of the airfoils is crazy town. I’m working on my flight instructor certificate and find your article very helpful for context. I was not aware of how this NACA bit all fit together.

    1. Many thanks, we are glad that you liked the article, and that is useful… And yes, NACA airfoils are in many airplanes as you noticed… Best regards,
