摘要

The flow field of a cruciform finned guided projectile with and without fin slot was simulated by the mean of CFD(computational fluid dynamic)numerical method. The characteristics of pressure field distribution without and different widths slots were calculated and compared. The influence of fin slot to the aerodynamic characteristics such as drag, lift, roll moment, pitch moment static aerodynamic characteristics as well as pitch, roll damping moment dynamic aerodynamic characteristics were emphasized in different angle of attack. The numerical results were certified by the good agreement between the wind tunnel test results. Important reference was provided to theoretical research and engineering for guided projectile shape design.
