Fluid Simulation (CFD) | Airfoil NACA 0020 - CAD creating - Part 1/3 | FreeCad

Creation and preparation of CAD airfoil profile for later meshing at Salome Meca and CFD analysis with OpenFoam.
The NACA 00XX airfoil shapes are two-dimensional profiles of airfoil for aircraft wings that were developed by the National Advisory Committee for Aeronautics (NACA).
The shape of the 4-digit NACA 00XX profiles is described by a formula:
y(t) = 5∙t∙(0.2969∙x^0.5 - 0.1260∙x - 0.3516∙x^2 + 0.2843∙x^3 - 0.1036∙x^4)
