Investigation of Velocity Distribution and Turbulent Energy for the Different Tip Shaped Projectiles
Öz
Velocity distribution on the projectile is a critical specification in terms of the range and perforation concept of the projectile. The shape of the projectile affects the amount of perforation energy. In this study, velocity distribution and turbulence energy are investigated for the projectiles on different tip shapes by using Solidworks Flow Simulation. Three different projectile nose shapes are examined in this study (sharpen, semi-rounded and rounded). Initial velocity is accepted to be 500 m/s for all situations. It is determined that the velocity is less affected on the sharpen type projectile where the penetration becomes easier. At the end of this study, velocity and pressure distribution on the penetrators in different tip geometries are obtained. The maximum velocity decrease at the tip of penetrator is found to be as 57.5% for the rounded type projectile. When the results are investigated, it is clear that velocity loss is about 22.2% in sharp type projectile.
