Abstract: This paper presents a new approach to establishing the interior ballistic algorithm for mortar systems based on thermodynamic theory.Contrary to previous studies, the processes that occurred in the ignition charges and the gas mixture properties in the barrel were considered in this study.The numerical integration method has been used to solve the problem with high accuracy.Numerical calculation applied on 100mm mortar.The calculation result is the law of pressure in the combustion chamber and the law of movement of the projectile in the barrel.These results are compared with the manufacturer's data to evaluate the reliability of the mathematical model as well as the solution method.According to the comparison between the simulation and the manufacturer's data, the maximum errors of velocity of 3.27%.The results obtained from this study are an important scientific basis for improving and optimizing the design of mortar systems and weapons with similar structures.
