Adoption of foreign and new domestic types of weapons and ammunition requires conducting a large amount of experimental research. However, the short-term nature of the processes that occur with ammunition on the trajectory complicates direct measurements of the quantities that characterize them, forcing the use of complex measuring and recording equipment. In this context, mathematical modeling of the processes of external ballistics and aerodynamics of ammunition movement comes to the fore.
The mathematical modeling method allows to significantly reduce the time and reduce the total cost of ammunition for their testing. Modeling methods, based on mathematical calculations and formulas, allow you to determine the future trajectory of ammunition based on a minimum set of parameters and in a short time. This method makes it possible to accelerate the compilation of temporary firing tables for the use of ammunition and accelerates their arrival to units that directly perform tasks in the combat zone.
Mathematical modeling methods allow us to obtain dependencies for determining the level of protection of military personnel when performing assigned tasks by units, taking into account the fact that the effectiveness of measures to ensure the protection of personnel depends on the type of protective barriers, effect of small arms bullets depends on their mass, shape, and bullet speed at the moment of encountering a protective obstacle.
The development of a scientific and methodological apparatus for conducting research to determine the parameters of new weapons and increase the ballistic protection of personnel from small arms remains an urgent scientific task.
The paper examines the process of interaction of a bullet with various types of protective environments. A method for determining the penetration ability of small arms bullets into protective equipment and models for determining the depth of bullet penetration into various types of obstacles are proposed. The results of calculations of the penetration depth of a bullet from an AK-74 assault rifle into various types of protective environments are presented. Further improvement of armor protection designs can be achieved by developing new technical solutions using the proposed method for determining the penetration ability of small arms bullets into protective equipment.
