We only deal with the 4-digit series of airfoils in this analysis. " The series is divided using digits from 1-8. The shape of the NACA airfoils is determined using a series of digits followed by the word "NACA. The NACA airfoils are just shapes of airfoils used for aircraft wings, which is developed by the National Advisory Committee for Aeronautics (NACA). In this analysis we deal with airfoil shapes known as NACA airfoils. Basically airfoils can be divided into many types by slightly varying their thickness, length, camber area and so on without after the shape. These shapes do not produce much drag compared to other shapes as so it is used in all aircraft structural parts which is subjected to airflow. INTRODUCTIONĪirfoils are the primary shapes which allow streamlined flow over it when it is driven through air. The results such as maximum lift coefficient, stalling angle, maximum lift to drag ratio and such parameters are obtained and are been compared with each other. These are obtained in the form of graphical representation by feeding data such as Reynolds number, Mach number, Angle of Attack and dimensions of the airfoils to the program.
