Abstract: An ordnance fuze having a selector rotor and an arming rotor initially held in an unarmed position by a rod which can be released by the rotation of a wind vane to move clear of the arming rotor and thus free the arming rotor to rotate to an armed position. A timer revolves a plate to block the movement of the rod after a predetermined time lapse if the vane has not already released it, thus preventing the arming of the fuze. An externally operated control limits the movement of the rod to either permit or prevent rotation of the selector rotor to direct the blast of the primer to either an instantaneous detonator or a delay detonator.

Abstract: An arming mechanism for an ordinance fuze which is protectively covered and sealed prior to deployment of the weapon containing the fuze. A prescored cover is torn from the fuze during deployment of the weapon to allow a plurality of vanes normally housed within the fuze to be extended externally of the fuze casing by a spring. The vanes are circumferentially constrained about an arming rod such that upon rotation within the airstream the arming rod is axially removed from the fuze detonator.
