Numerical investigation of hybrid blend design target bullets

Abstract

In the past few decades, researchers are involved in the studies of high-energy penetrator geometry and also the materials used for causing brutal damages on enemy targets. The highly focused area in this field is the shape of the nose and penetration angle of the penetrator. Hybrid blend design target bullets is one among the best aerodynamic design as it is having two different shapes within the nose. The design of these bullets plays an influential role in terms of aerodynamic characteristics and its dynamic performance capability on hitting the targets. Objective of this research is to perform a comparative analysis of 3 different geometrically varied shapes of these bullets by numerical simulation using CFD, based on its performance characteristics such as aerodynamic co-efficients, shock wave existence, Turbulent dissipation rate and normal drag force on the bullet surface.
