This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. This empirical approach, which involved modifying the geometry of an existing airfoil, culminated in the development of the four- and five-digit-series airfoils in the mid 1930’s (Refs. This series was significant because it represented a systematic approach to airfoil development as opposed to earlier, random, cut-and-try approaches. Munk, was tested in the Langley Variable-Density Tunnel (Ref. The first series of airfoils, designated “M sections” for Max M. Shortly thereafter, the development of airfoils by the NACA was initiated at the Langley Memorial Aeronautical Laboratory (Ref. By 1920, the Committee had published a compendium of experimental results from various sources (Ref. In its first Annual Report to the Congress of the United States, the NACA called for “the evolution of more efficient wing sections of practical form, embodying suitable dimensions for an economical structure, with moderate travel of the center of pressure and still affording a large range of angle of attack combined with efficient action” (Ref. From its very beginning, the National Advisory Committee for Aeronautics (NACA) recognized the importance of airfoils as a cornerstone of aeronautical research and development. ![]()
