ABSTRACT:
An explosive logic safing device for increasing the safety and reliability f a detonation signal from a fuze to an explosive charge. The safing device is provided with an inlet explosive trail which conveys an inlet detonation signal to an outlet explosive trail and the primary explosive charge. A control explosive trail connects the inlet explosive trail and the outlet explosive trail. A failure explosive trail is connected between the control explosive trail and the outlet explosive trail, and is provided with an explosive logic network for conveying the inlet detonation signal from the inlet explosive trail to the outlet explosive trail when a plurality of detonators are properly initiated. The explosive logic network is also provided with a means for registering the successive initiation failures of individual detonators.
