UVOD / INTRODUCTION:

The production and design of artillery weapons is a complex and expensive process. Usually, the design of such systems is based on the experience of previous models or their modifications. The tendency is to unify most of the basic elements, which are also used in other weapon systems. Tactical requirements generally define initial and boundary conditions during project setup. The basic element of every classic artillery system is the barrel, which is the most complex to design and produce.

The purpose of the paper is to present the process of barrel redesign, specifically changing a caliber of an existing barrel to a new caliber, taking into account various methods in order to determine the optimal design that would ensure the longest possible service life of the weapon system. In addition to the barrel design, an optimization of the propellant charge was carried out, i.e., variation of the gunpowder characteristics that directly affect the internal ballistic processes occurring in the barrel during firing.

The barrel was redesigned based on known data from an existing system and results obtained from the optimal configuration of gunpowder characteristics. The practical application of such a barrel is uncertain, which is why a numerical simulation of the loading conditions during firing was conducted. Numerical analysis was conducted by applying static stress in the region experiencing the maximum loads, along with variable loading conditions in the same area, to evaluate the structural durability of the designed barrel.
