Abstract:

Aiming at researching aerodynamic characteristic of projectiles. This paper builds three simulation models with fins in different amount and appearance, by using CFD software to generate meshes of each model, it simulates the changing laws of drag coefficient, lift coefficient and pitching moment coefficient and analyses correct ability and flight stability of each model according to the data, simulation results indicate that projectile with folded fins have better aerodynamic appearance and can be studied deeper, it provides aerodynamic reference for future research.
