Jump to:USAF Digital Datcom
The United States Air Force (USAF) Stability and Control Digital DATCOM is a multi- purpose program written in FORTRAN that calculates the stability and control of an aircraft through analysis of its basic geometric structure. In addition, the DATCOM takes into account variable flight conditions (such as Mach and altitude) and the aircraft\'s propulsion elements. The DATCOM is able to compile meaningful aerodynamic coefficients that closely describe the performance and stability of the aircraft in numerous flight conditions.

OpenDatcom
OpenDatcom uses an advanced GUI/development environment that allows the user to easily compile the input file and run DATCOM without any knowledge of DOS or the necessary FORTRAN formatting. In addition OpenDatcom processes, compiles, and exports the generated export of stability and performance coefficients. This feature was added with the specific intention of compiling three dimensional stability tables which can be copied straight into the FlightGear (using the JSBsim flight model) open source flight simulator. This allows for an aircraft to be analyzed in DATCOM and its flight to be tested in FlightGear.

Athena Vortex Lattice (AVL)
AVL is a program for the aerodynamic and flight-dynamic analysis of rigid aircraft of arbitrary configuration. It employs an extended vortex lattice model for the lifting surfaces, together with a slender-body model for fuselages and nacelles. -Mark Drela (Creator, Professor MIT)

Plot Datcom 3D
In 2008 Professor Glenn P. Greiner and (then student) Jafar Mohammed created a collection of MatLAB scripts which would allow the user to create a three dimensional model of the aircraft from the Digital Datcom input file. They called the collection Datcom3D. Mostly copying and pasting geometry data from the for005.dat input file into an easy to use master template and running the files creates a complete model which can be rotated, panned, resized and double checked for accuracy.
| Release Name | Status | Description | Release Date | |
|---|---|---|---|---|
| Plot Datcom 3D 1.2 | stable | Modify datcom3d_template.m file and launch it. The script then makes function calls to the other files located in the folder. | 2010-06-21 | Download ./. |
