THE METHOD OF STRENGTHENING OF DURABILITY OF A MORTAR BARREL

Abstract

The subject of the article is an assessment of the possibility of improving the security of the personnel of units during the operation of mortars. The purpose of the article is to study the possibility of increasing the strength of mortar barrels. The task is to analyze the causes of the increased deaths of mortar fire teams during the operation of mortar barrels. Identify the main areas of work to prevent mine explosions in the mortar channel and identify ways to eliminate them by improving the methods of combat use; keep security measures during the shooting; increase the technical training of the personnel of the units; development and use of new technical solutions for the development of mortars. The work considers and suggests an analytical method for increasing the strength of mortars, based on the application of the principle of combined structures. As a result of the researches the model of definition of the resulted pressure and limiting pressure in the combined cylinders is offered. The results of calculating the limiting pressure in cylinders are given in the paper. Conclusions: the article investigates the possibility of increasing the strength of mortars. The theory of combined cylinders was proposed to increase the strength of mortars. The calculation of the internal pressure for the construction of the mortar in the form of combined cylinders is carried out. Further studies are related to the fact that the theory of combined cylinders creates prospects both in the development of high-pressure technology and in the creation of lighter and more stable structures.
