About the program

This function generates a set of points containing the coordinates of a NACA airfoil from the NACA 4 Digit Series, NACA 5 Digit Series and NACA 6 Series given its number and, as additional features, the chord, the number of points to be calculated, spacing type (between linear and cosine spacing), opened or closed trailing edge and the angle of attack of the airfoil.
It also plots the airfoil for further comprovation if it is the required one by the user.

INPUT DATA

n --> NACA number (4, 5 or 6 digits)

OPTIONAL INPUT DATA

c --> Chord of airfoil (m) (1 m default)  
s --> Number of points of airfoil (1000 default)  
cs --> Linear or cosine spacing (0 or 1 respectively) (1 default)  
cte --> Opened or closed trailing edge (0 or 1 respectively) (0 default)  
alpha --> Angle of attack (º) (0º default)  

OUTPUT DATA

x_e --> Extrados x coordinate of airfoil vector (m)  
x_i --> Intrados x coordinate of airfoil vector (m)  
y_e --> Extrados y coordinate of airfoil vector (m)  
y_i --> Intrados y coordinate of airfoil vector (m)
