F42C15/00Arming-means in fuzes Safety means for preventing premature detonation of fuzes or charges

F42C15/005Combination-type safety mechanisms F42C15/16wherein the firing pin is displaced out of the action line for safety F42C15/18wherein a carrier for an element of the pyrotechnic or explosive train is moved F42C15/184using a slidable carrier F42C15/188using a rotatable carrier F42C15/192rotatable in a plane which is parallel to the longitudinal axis of the projectile F42C15/196by the action of centrifugal or inertia forces on the carrier body F42C15/20wherein a securing-pin or latch is removed to arm the fuze F42C15/21using spring action F42C15/22using centrifugal force F42C15/23by unwinding a flexible ribbon or tape F42C15/24wherein the safety or arming action is effected by inertia means F42C15/26using centrifugal force F42C15/28operated by flow of fluent material F42C15/285stored within the fuze housing F42C15/29operated by fluidic oscillators operated by dynamic fluid pressure F42C15/295operated by a turbine or a propeller Mounting means therefor F42C15/30of propellant gases F42C15/31generated by the combustion of a pyrotechnic or explosive charge within the fuze F42C15/32operated by change of fluid pressure F42C15/33by breaking a vacuum or pressure container F42C15/34wherein the safety or arming action is effected by a blocking-member in the pyrotechnic or explosive train between primer and main charge F42C15/36wherein arming is effected by combustion or fusion of an element; Arming methods using temperature gradients F42C15/38wherein arming is effected by chemical action F42C15/40wherein the safety or arming action is effected electrically F42C15/42from a remote location F42C15/44Arrangements for disarming, or for rendering harmless, fuzes after arming
