skyward-datcom-parser

A simple Python script to parse Missile Datcom Output File

This simple Command Line script converts the for006.dat Missile Datcom 97 output file to a MATLAB .mat file. It has been implemented to retrieve the data for a standard simulation without deflections.

The version is pre-alpha so it could behave very buggy.

Usage

python datcom_parser.py filename

The filename is optional. Without it the parser will look for the `for006.dat' file.

Output File

The Output file is composed by two structures: Coeffs and State. Coeffs contains all the aerodynamic coefficients interpolated over the 4 states (AoA, Mach, Altitude, Sideslip angles) and the struct State contains the set of states (Aoa, Mach, Altitude, Sideslip Angle) the coefficients have been calculated on and the position of the center of gravity.
