Abstract

The article analyzes possible factors and causes that affect barrel wear during firing. The shortcomings that affect the density and range of fire are identified and methods for increasing the survivability of barrels are proposed. Ways are identified to improve design solutions, the choice of materials and protective technologies that allow significantly increasing the barrel resource during their development and manufacture.

The survivability of a small arms barrel is the number of shots that it can withstand without a significant deterioration in combat characteristics. A decrease in accuracy, a decrease in accuracy of fire, erosion of the rifling or critical wear of the barrel bore are indicators of resource exhaustion. In modern weapons, survivability is determined not only by the number of shots before destruction, but also by maintaining combat effectiveness throughout the entire service life.

Calculation of the survivability of the barrel is an important stage in the creation of modern small arms. Accurate forecasting of the life allows to reduce the number of failures in combat conditions, increase the efficiency of firing, and optimize the logistics of technical maintenance. Thanks to modern modeling technologies and the use of the latest materials, the survivability of new generation weapon barrels is constantly increasing, making them more reliable and durable in real operating conditions.

Keywords: barrel, survivability, density of fire, weapon.
