ABSTRACT:
An out-of-line fuse for primarily ring-type, multiple point concurrent initiation, projectiles is disclosed. In the unarmed state, the detonator and booster charges are angularly displaced while located at the same radial distance from the projectile axis in adjacent radial planes. When rotation of the projectile is sensed by a plurality of centrifugally actuated fiber optic light switches arranged in a series optical relationship, an electrically activated pyrotechnic thruster is fired to move the detonator charges and the booster charges into alignment arming the projectile; the electrical circuit having been priorly energized by inertia switches sensing the thrust forces during the launching of the projectile. When rotation of the projectile substantially ceases the detonator charges are electrically fired.
