Analytical Method for the Estimated Calculation of the Required Amount of Propellant Charge for the Reusable Training-Practice Mortar Round for Small Distance Firing

The paper presents an analytical method for determining the estimated amount of propellant charge for the reusable training-practice mortar round intended for short distance firing, as a part of simulator for mortar crews. For verification of the analytical method an experimental research was conducted where the 82mm training-practice mortar round was fired at a distance of 100 meters. The experimental research and the verification of the statistical hypothesis confirm that the formula can be used to practically determine the required amount of propellant charge.
