  This file has three compressed files NAC4GEN2.EXE, NACA.DXF
and a Readme file  

  NAC4GEN2.EXE is a program that generates the coordinates of a
NACA 4 digit Airfoil section.  It was written in Fortran.  It
lets you scale the foils, plots them on the screen, and gives
some of the coordinates. 

NACA 4 digit airfoils are Good for low reynold number
applications. They are used  homebuilt, general Aviation, WWII,
and model airplanes.  Used on boats for keel, rudders,
centerboard, and hydrofoils


Version 2 CORRECTS a small problem that was causing a warning
about Math Error after program ran for 1 Airfoil section.  This
error did not affect results.  It also, allows your to scale
greater than 100, so you can uses Centimeter, Millimeters, or
large foils. Also allows you to repeat the program with out going
thought dos.
  
NACA.DXF is a DXF file of a NACA 4 digit Airfoil.  It can be
imported  into many CAD programs.  It was generated by a program
call NACA4DXF.EXE,  Which is like NAC4GEN2.EXE.
  
These Program are written by Mr. Harold Ginsberg (PE) who has a
BS in Aerospace Engineering.
