Abstract

The paper focuses on the influence of bearing band on the flow field and aerodynamic force of the projectile. Numerical model of projectile with and without bearing band are simulated under a supersonic flow condition. The flow field parameters and the aerodynamic drag coefficient of models were obtained. The numerical results indicate that the bearing band causes a detached bow shock in front of it and increases the aerodynamic drag of the projectile obviously. Along the surface of the projectile, the bearing band leads to flow separation, but reattached soon.
