NACA 4 digit Airfoil Generator

"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.
