ABSTRACT:
A fuze apparatus arms itself in flight and is especially adapted for use in training shells. The fuze has a casing with ignitable or explosive material located therein and an igniter mounted to ignite the ignitable material upon a sufficient impact against the igniter. The fuze is armed in flight by a movable cup moving against the spring bias which moves relative to the fuze casing by inertial force during acceleration, which allows an arming member to slide or roll between the sliding cup and the igniter where it is held until sufficient impact generated by inertial force from a larger mass is directed against the cup, driving the arming member against the igniter.
