The aim of this work was to obtain mortar with a higher initial velocity and lower pressure of powder gases. Aanalysis of the Internal ballistics (IB) parameters in the design phase of the 82 mm M69 mortar was perforormed using mathematical model of the Serebryakov method. In order to see the influence of certain parameters on the pressure of the gunpowder gases in the barrel and the initial velocity were first calculated with unchanged IB parameters, and then the influential parameters were varied in a certain range. A comparative method of calculating IB parameters is presented in a tabular way. By optimally varying IB parameters in the range of ± 5%, the maximum pressure was reduced while the initial velocity was increased, which was the aim of this work.
