PROGRAM NAC4GEN Version 2.1" (C) BY Mr. Harold Ginsberg;May1995, Dec 1995, Jan 1996" B.S. AEROSPACE ENGINEERING" This program calculates & plots naca 4-digit airfoil section" It is written in Microsoft Fortran Ver 5.1.
It is based on formulas published in several books. It is accurate compared to published data. Circulated as shareware you can circulated it. You may not change it in any way, sell it, or use it in other programs.
This is version 2.1 It is a little more user friendly because it allow you to reenter if you make a mistake on the 1) & 2) questions.
Version 2. Corrected a small problem that was causing a warning about Math Error after program ran for one 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.
