ABSTRACT:
It happens time and again that a fuze does not function and that the projectile remains in the field or the place where it landed as a dud. When such a dud is found the danger exists that it might explode upon the finder's touch or when moved or lifted. To prevent this danger the impact fuze in a dud should be able to de-arm itself in a non-explosive manner. This is achieved by positioning a dud insert or de-arming device between an explosive or firing train and a booster charge. This dud de-arming device contains an escapement device which after a predetermined delay time following impact of the projectile moves a rotor from its armed or live position into its de-armed or inert position. The dud de-arming device contains structure which, by virtue of the impact delay or deceleration, that is a delay in ignition of the booster charge upon the projectile hitting the target or ground, activates the escapement mechanism.
