Low voltage primary free detonator

A low-voltage, primary-free detonator, comprising:

• a ballistic vessel comprising a detonator shell comprising
• an open end,
• a closed end,
• a hollow interior extending between the open end and the closed end, and
• a deflagration to detonation transition (DDT) section extending along at least a portion of the hollow interior, wherein the DDT section comprises a reinforcement area extending from an inner surface of the detonator shell towards the hollow interior;
• a pyrotechnical material disposed within the DDT section;
• and
• a multilayered main explosive load disposed within the hollow interior of the detonator shell between the pyrotechnical material and the closed end;
• wherein the pyrotechnical material is a multilayered pyrotechnical material comprising two pyrotechnical layers, with each pyrotechnical layer having a different pyrotechnical pressed density, and
• wherein upon initiation of the detonator, the DDT section confines a burning gas within the hollow interior to linearly increase a burn speed of the pyrotechnical material until the burn speed reaches a detonation velocity of at least 6000 m/sec.

A detonator, comprising:

• a detonator shell having an open end, a closed end, and a hollow interior extending between the open end and the closed end;
• a reinforcement area extending along at least a portion of the hollow interior;
• a pyrotechnical material at least partially disposed within the reinforcement area;
• and
• a multilayered main explosive load disposed within the hollow interior of the detonator shell between the pyrotechnical material and the closed end;
• wherein:
• the pyrotechnical material comprises a multilayered pyrotechnical material;
• the multilayered pyrotechnical material comprises:
• a first pyrotechnical layer comprising a first pyrotechnical pressed density;
• and
• a second pyrotechnical layer comprising a second pyrotechnical pressed density;
• and
• the first pyrotechnical pressed density differs from the second pyrotechnical pressed density.
