Abstract
Firearms play an important role in the defense industry. Various researches have been carried out to increase the range, destructiveness and stabilization of these weapons. However, one of the important factors affecting these parameters is the design of the projectile core. Aerodynamic improvements in the core design can increase the range without changing the weapon design. In this study, the effect of the 7.62x39 mm bullet core on the aerodynamic flow behavior around it was investigated. The air flow over the projectile core is analyzed in ANSYS Fluent program.
