Abstract

The presented study is focused on the idea to develop a thermo-chemical model for calculations in the interior ballistics, which is based on the first law of thermodynamics for the open system of variable chemical composition. This one governing equation is completed by influences of: the rate of burning and the propellant gases release by combustion of propellant, heat transfer, frictional losses, etc. The problem is solved using the MATLAB code. The result of the solution represents the determination of the time courses of the propellant gases chemical composition, the pressure, the temperature, the bullet travel, and the bullet velocity. The developed computer program can be used for various tasks in the interior ballistics of arm guns. Presented model and program was validated for the case of 9 mm Luger cartridges. © 2021 IEEE.
