ABSTRACT:
A fuse for a spinning projectile comprises a rotor having safety elements which prevent rotation of the rotor to an active position. The safety elements are arranged such that when the safety elements are properly installed, the center of gravity of the rotor induces rotation of the rotor in a first direction toward the active position. An escapement mechanism regulates the rate of rotation of the rotor in such first direction. A stop prevents rotation of the rotor in the opposite direction. When a safety element is missing, the center of gravity is positioned to induce rotation of the rotor in such opposite direction in which the rotor cannot rotate.
