Mechanical time delay safety and arming mechanism

摘要

A base member mounted on a projectile with a movable member mounted thereon for radially outwardly sliding movement in response to spinning of the projectile, the movable member having a center of gravity located at a first point which prevents the sliding movement thereof and the center of gravity being shiftable to a second point by the controlled flow of a predetermined mass, e.g. steel balls, which shifting of the center of gravity allows the movable member to slide from the safe to the arm position.
