  • Warhead fuse
    Patent number: 9638504
    Abstract: A warhead fuse mechanism is used to prevent an accidental explosive event of a warhead by separating the booster lead into a plurality of booster lead segments, with each of the individual booster lead segments having a diameter less than the failure diameter of the booster lead explosive. A separating device separates the booster lead segments from each other to maintain the failure diameter until detonation is desired.

  • Weapon fuse method
    Patent number: 7895947
    Abstract: A warhead fuse mechanism is used to prevent an accidental explosive event of a warhead by positioning a booster lead carrier, having a booster lead segment, positioned between the warhead detonator and warhead explosive. In a safe position the booster lead segment is off-set from alignment with the warhead detonator and warhead explosive. The warhead fuse is armed by rotating either the warhead detonator or booster lead carrier to align the warhead detonator and booster lead segment to form a detonation chain between the warhead detonator and warhead explosive.
