The Ferrari F40 sports car has "NACA style" side and hood scoops.. It is especially favored in racing car design. [4] [5] Sports cars featuring prominent NACA ducts include the Ferrari F40, the Lamborghini Countach, the 1996–2002 Dodge Viper, the 1971–1973 Ford Mustang, the 1973 Pontiac GTO, the 1979 Porsche 924 Turbo, the Maserati Biturbo, the Nissan S130, and the Porsche 911 GT2.
NACA experience provided a model for World War II research, the postwar government laboratories, and NACA's successor, the National Aeronautics and Space Administration (NASA). NACA also participated in development of the first aircraft to fly to the "edge of space", North American's X-15. NACA airfoils are still used on modern aircraft.
Schemes have been devised to define airfoils – an example is the NACA system. Various airfoil generation systems are also used. An example of a general purpose airfoil that finds wide application, and pre–dates the NACA system, is the Clark-Y. Today, airfoils can be designed for specific functions by the use of computer programs.
The lightweight Mustangs had a new wing design. The airfoil was switched to the NACA 66,2-(1.8)15.5 a=.6 at the root and the NACA 66,2-(1.8)12 a=.6 at the tip. These airfoils were designed to give less drag than the previous NAA/NACA 45-100. In addition, the planform was a simple trapezoid, with no leading edge extension at the root. [25] [49]
Streamlines around a NACA 0012 airfoil at moderate angle of attack. A foil generates lift primarily because of its shape and angle of attack.When oriented at a suitable angle, the foil deflects the oncoming fluid, resulting in a force on the foil in the direction opposite to the deflection.
Eastman Jacobs joined NACA in 1925 after earning a bachelor's degree in Electrical Engineering at the University of California, Berkeley. He applied at the Bell Labs but was not accepted and opted for his second choice Langley. His knowledge of complex analysis was key to current airfoil design techniques at the time. [1]
