T'Ie description of airfoils of t he NACA four-digit series slthows that tte necessary data may be fouled from the NACA 00)12 thickness form and 64 mean line in the supplementary figures. Many plane designers, don't even approximate and they don't even have a simulated data for the proper airfoil, but for example they use NACA 2412 for a plane that is supposed to have e. Various standards are available, including NACA 65 series, such as the NACA 65010 I was working with. the airfoil designer, and as a result many otherwise excellent airfoils are never put into practical use. Some additional tools for creation and modification of airfoils have been added to fill the toolbox. An example: NACA 23012, is a 12% thick airfoil, the design lift coefficient is 0. You have 0 airfoils loaded. 24” (4% x 6”). As the power of the PC increases, engineers now have access to tools to screen blades that operate poorly in the transonic regime of flight.
