A 4 digit NACA airfoil plotter. This app plots these airfoils and let the user watch the effect each parameter has on the shape of the airfoil. The airfoil rotates following user screen drags. A little nice tool for learning the basics of NACA airfoils shapes. This app may be usefull for airplane modeling, RC enthusiasts, wind turbine, boat, rudder designers, teachers, aerodynamics and hydrodynamics students.
