| dc.description.abstract | Developing gun systems require the studying and development of the bullets that are consumable supplies. By the improvement works in the field of materials and geometry, the production of bullets whose destroying forces, ranges, stabilization of movement and access to the target are improved was being studied. In this study, the effect of riblet and dimple formed body surface of a 9 mm parabellum type light core bullet on the aerodynamic flow behaviour around the bullet was discussed. Airflow around the bullet core was investigated by the computational fluid dynamic base software Fluent. The compressible airflow was analysed with the Spalart Allmaras turbulence flow model, considering the viscous effects due to Sutherland's law. In this study, it was concluded that the riblet and dimpled surface formed bullet geometry could lead to an increase of bullet velocity and a decrease in shear stress and drag force. It was evaluated that the dimple and riblet formed bullet surface provides positive contributions to its range as well as stabilization in bullet motion. | en_US |
