The NACA 2412 is not glamorous. It cannot break the sound barrier. It does not win efficiency contests. But if you need a wing that will fly reliably in ice, rain, and heat; that will warn you before it stalls; and that can be built easily from sheet metal—you choose the 2412.
The nomenclature of the NACA 2412 follows the standard four-digit system developed by the National Advisory Committee for Aeronautics: naca2412
The NACA 2412 is a cambered (asymmetrical) airfoil, meaning it can generate lift even at a . This gives it a significant advantage over symmetrical airfoils like the NACA 0012 , which require a positive angle of attack to produce lift. The NACA 2412 is not glamorous
: The final two digits signify the maximum thickness , which is 12% of the chord length. Aerodynamic Characteristics and Performance But if you need a wing that will
