Investigation of the velocity, mach number, and turbulent parameters for different projectile rear geometry
Öz
A firearm projectile consists of four main parts. The end part of the cartridge is called the bullet (core). When the weapon is fired, the bullet (core) shoots towards the target. In the literature, there are studies examining projectile geometries in terms of projectile velocity, range, and impact factor. By redesigning the geometric features, the velocity and turbulence states of the bullet can be improved. Therefore, in this study, a projectile with different rear geometries is analyzed in terms of velocity, turbulence energy, and Mach number. For projectile rear geometry, Sharp, 45-degree, and curved rear geometries are analyzed. After the analysis, parameters such as velocity, turbulent energy, and Mach number were analyzed. The results were then compared with each other and the most effective geometry was obtained.
