460, "The Characteristics of 78 Related Airfoil Sections from Tests in the Wind Tunnel." This report also resulted in the creation of the four-digit scheme for defining the basic geometry of the airfoil. In 1933 the NACA tested 78 airfoil shapes in their wind tunnels with the data being published in Technical Report No. In an attempt to better understand what made a good wing, the National Advisory Committee for Aeronautics, henceforth referred to as the NACA, was founded.
