Method and apparatus for executing a weapon safety system utilizing explosive flux compression

An activation system of a munition for activating a warhead or a propulsion system of the munition, the activation system comprising:

• an initiator interface that activates the warhead or the propulsion system;
• a circuit detonator including explosive material encased by a detonator housing;
• and
• an inductor coil wrapped about the detonator housing and about a longitudinal coil axis between opposed first and second longitudinal ends of the inductor coil, the inductor coil having lead turns at the first longitudinal end of the coil and lag turns at the second longitudinal end of the coil;
• wherein detonation of the explosive material causes the detonator housing to expand radially outwardly, causing the inductor coil to short and causing current in the inductor coils to increase and to be directed into the lag turns of the inductor coil until the subsequently increased current is released from the lag turns into the initiator interface, thus activating the initiator interface.

A method of activating a warhead or a propulsion system of a munition, the method comprising the steps of:

• switching a first logic element of the munition to allow the flow of current from a first power source of the munition to an inductor coil of the munition;
• subsequent to the switching of the first logic element, switching a second logic element of the munition to allow the flow of current from the first power source or a second power source of the munition to a circuit detonator of the munition to trigger radially outward detonation of a detonator housing of the circuit detonator;
• shorting turns of the inductor coil via physical interaction of the inductor coil with a portion of the detonated detonator housing;
• and
• activating an explosive foil initiator of the munition that is communicatively connected to the warhead or propulsion system via flow of current released from the inductor coil, wherein the release is caused by the detonation of the circuit detonator.
