The article summarizes the results of a shooting experiment aimed at comparing the effects of two types of hollow point handgun bullets — Action 5 and the newly developed AM-D, both of calibre of 9 mm Luger. The firing tests were carried out against an etalon fuselage target representing the airframe fuselage structure of a transport airplane. The firing was performed both directly at the etalon target...
This article deals with the problems connected with the camera calibration techniques applied on a projectile velocity measurement using the single camera photogrammetry. The two methods of a camera calibration are compared. Furthermore, the results obtained using the camera measuring system are compared with the results using the classical ballistic measuring system of the third generation, the optical...
The article analyzes the relationship between frangibility of frangible bullet and its impact velocity. Based on the results of extensive shooting experiment, the analytical functional dependence of frangibility coefficient on impact velocity of the bullet on standard hard target — plate Hardox 450 of thickness 10 mm is determined. The effect of the difference between the mass of the captured fragments...
The paper is focused on the development of a thermodynamic mathematical model describing the internal ballistic phenomena, taking place within working chambers of an airgun. The objective is to derive a governing equation modeling the change of gas temperature in a control volume subsuming several incoming and outgoing mass airflow rates. A novel algorithm for solving internal ballistics of all types...
This article deals with the evaluation of the effect of the small arms cartridge lubrication on the operation cycle of the automatic and the semi-automatic weapon. The course of the weapon's operation cycle has been measured using the digital high speed camera, utilizing the single-camera digital photogrammetry method.
The article describes analysis of energetic relations during penetration of pistol bullet through human head substitution. Relation between two essential characteristics of residual wound potential of the bullet after penetration of the head — specific impact energy of the bullet and the depth of bullet penetration into substitute biological material is derived. The general solution of the problem...
