PROJECTILE WITH ROTATIONAL MOTION

摘要

A projectile (11) and a projectile mount (22) having a central bore (23) into which the projectile (11) is mounted includes rotational formations functionally engaging between the projectile (11) and the projectile mount (22) which in use provides rotational motion to the projectile (11) around an axis of rotation by the propulsion of the projectile along the axis of rotation. The rotational formations form a vortex outlet to form a gaseous bearing between the projectile (11) and the projectile mount (22) and to impart vortex rotational drive on the projectile (11) to enact explosive expulsion.
