Abstract

At the end of flight, spin stabilized projectiles tend to experience dynamic instability resulting in tumble and reduced aerodynamic and terminal ballistics effectiveness. This instability is largely attributable to an increase in magnitude of the Magnus moment and transient fluctuations of the same coefficient as the projectile decelerates into the transonic flight regime...
