NACA 4 digit Airfoil Generator

Generates the NACA 4 digit airfoil coordinates

Description

"naca4gen.m" Generates the NACA 4 digit airfoil coordinates with desired no. of panels (line elements) on it.

FEATURES:
 *Accurate coordinate generation with the required precision
 *Option to generate closed or open Trailing Edge
 *Additional separate outputs for camber line, upper surface and lower surface
 *A tst (test) file included

INPUTS:
[1] NACA 4 digit designation (eg. '2412')
[2] No of panels (line elements) PER SIDE (upper/lower)
[3] Type of chord station spacing (Half cosine spacing / Uniform spacing)

OUTPUTS:
[1] One can plot the generated airfoil, camber line and the leading edge circle by setting an option input wantPlot=1
[2] A data file can be generated by setting the option input wantFile=1

EXTENSION:
Being a function, the airfoil generator can be called several times from a loop to generate any number of airfoil data files.

Hola amigo, en realidad me parece muy noble de tu parte colgar la programacion del naca asi me puedo guiar para proximos trabajos.
