FORMALIZATION OF DEPENDENCE ON THE INFLUENCE OF CHANGING INITIAL SPEED SHORT-WEAPON WEAPONS AT THEIR IMPRESSIVE PROPERTIES

Abstract

The article deals with the formalization of the dependence of the influence of changes in the initial velocity of small arms on their striking properties. Considering the enemy manpower damage, the main purpose of the pistols to determine the effect of changing the initial velocity of the bullet on its interaction with the purpose considered the main striking properties of the bullet: the killing, stopping and punching action of the bullet.The dependence of the killing effect of the bullet on its velocity at the moment of the target was obtained and it was found that at lower velocities of pistol bullets of 9 mm caliber at the point of encounter with the target, the killing effect of these bullets would be correspondingly less than permissible, in which case the target would not be guaranteed hit.Installed for 9 mm calibers: dependencies of the velocity reduction of the spheres on the distance, which are calculated as polynomial trend lines of the 3rd degree; minimum permissible distances to targets at which the velocity of the bullets will not decrease less than the table, nor will the distance of the guaranteed bullet action of the bullet be reduced depending on the shelf life of ammunition calculated similarly to the previous one, as polynomial trend lines of the 2nd degree;the proportional dependences of the reduction of the stopping action of the ball to increase the distance to the target, in which the stopping action of the ball will not decrease less than the table; the dependence of the punch action of the ball on the shelf life of ammunition, which is defined by the corresponding function, calculated similarly to the previous ones, as a polynomial trend line of the 2nd degree.The average experimental data of the magnitude of the initial velocities of the revolver bullets of long-term storage of the 7.62 mm caliber are presented and the data of the depth of their penetration into the obstacle are obtained, which is presented clearly.Conclusions and recommendations are provided to ensure the accuracy of small arms, including shotguns and ammunition, as well as the tasks that need to be undertaken in the future to accomplish this task.
