  2. NACA airfoil - Wikipedia

    en.wikipedia.org/wiki/NACA_airfoil

    TT: the maximum thickness in percent of chord, as in a four-digit NACA airfoil code. For example, the NACA 23112 profile describes an airfoil with design lift coefficient of 0.3 (0.15 × 2), the point of maximum camber located at 15% chord (5 × 3), reflex camber (1), and maximum thickness of 12% of chord length (12).

  5. Airfoil - Wikipedia

    en.wikipedia.org/wiki/Airfoil

    For example, an airfoil of the NACA 4-digit series such as the NACA 2415 (to be read as 2 – 4 – 15) describes an airfoil with a camber of 0.02 chord located at 0.40 chord, with 0.15 chord of maximum thickness. Finally, important concepts used to describe the airfoil's behaviour when moving through a fluid are:
