Abstract

Present paper proposes, through numerical simulations, some optimization possibilities for an innovative concept aimed to control the magnus effect induced by the high spinning velocity of a Secant–Ogive–Cylinder–BoatTail projectile. It appears that with a relatively small contra-spinning surface, the lateral force can be drastically reduced on a wide range of flight conditions. Present computations confirm experiments in supersonics and extend them for high subsonic and transonic regimes for small angles of attack.
