These are executables that replace the NACA 1135portions of Aerocal Pak#1 above, which doesn't run on many computers anymore. These codes compute the compressible flow functions given in NACA 1135, plusa few more useful relations. A one line changeis required to run it on an IBM type PC. It has the NACA 1135 tables, Prandtl-Meyer angle and inverse, properties of oblique shocks, the Rayleigh/Fanno line table and the 1976 standard atmosphere.Originally written for a programmable calculator, the code is inQuickBASIC, and runs as is on a Mac with QuickBASIC.
This software is a BASIC program that implements the old Aerocal Pak #1, Basic Aerodynamic Relations.

Other useful online Java-based programs are available at Another source of classic aerodynamics codes is the CD sold by Ralph Carmichael, Public Domain Aeronautical Software (PDAS). And these codes are of course for educational use only.
The input file must match the example input file exactly (The number of spaces between the columns and before the first column of numbers must match the example code) Finally, the programs and manuals change as students suggest clarifications and other improvements. ( C:\User\Documents\VT 2016, The space between "VT" and "2016" will not be recognized by the code)2. Do not have any spaces in the directory name, Ex. Finally, a student has further suggestions and tips for using the codes. Always use a folder with user permissions to output data files to such as Documents.
exe files are run as user however, the default file output location isusually C: which is an administrator directory and will create an error at run time due to permissions issues. Finally, students often have permissions issues with windows *.exe files:All. Add dealing with these variations to your computationalengineering toolbox. Recall CR means carriage return and LF means line feed. Remember that for PCs (Windows) the lines are terminated with a CR/LF, for a "classic Mac" the lines end with a CR, while for unix (and modern Macs) the lines are terminated by an LF. Note: files here may be posted in various formats. In some cases I have now added links to sites located elsewhere, where key codes are available.
For pointers on running codes, read the chapter from my Applied Computational Aerodynamics notes, Computers, Codes, and Engineering (a pdf file). For example, F10 means a real number (with a decimal point) taking 10 spaces.Study the sample input files for examples of how this works (in fact, ALWAYS run the sample case before doing anything else with these codes). Do yourself a favor and learn what this means. The spacing definitions use FORTRAN terminalogy. The input instructions are often given as cards, from the days when the text files were physically a deck of computer cards. ALSO, the location of the inputon each line is critical. Important Note: Many of these programs require a text file as input. In addition, some methods are given as MATLAB m-files. However, I’ve recently started adding executables since the FORTRAN source files typically can’t be used by current undergraduates.
Originally they were all FORTRAN source code. Theseare mostly old-fashioned codes without graphical user interfaces. This page contains programs that may prove useful to aerodynamics and design class students.
