Abstract
In this study, aerodynamic damping characteristics of a spike-nosed projectile were investigated by numerical simulation methods. The numerical process was conducted using ANSYS Fluent software for specific projectile122 mm. Effect of mesh volume on the convergence of the results was investigated in details. Aerodynamic characteristics of the projectile such as drag, distribution of pressure, velocity on the surface model were presented. The results of this study were used to evaluate the effect and results of spike for projectile 122 mmduring the flight in particular, and other projectiles using spike for stability in general for further studies.
