  • Patent number: 4892039
    Abstract: A ring detonator device for a warhead transfers a point initiation to the ng detonator. The detonator device is comprised of an inner and outer conically shaped member with the outer conically shaped member having the shape of a modified frustum of a circular cone due to a cylindrical member extending from the smaller base of the outer conically shaped member. The space between the inner and outer conically shaped member contains an explosive composition which is discharged as a shock wave and detonation products after ignition in a ring configuration by a common cylindrical portion extending from each of the larger bases of each conically shaped member to align the space therebetween perpendicular to the bases of the conically shaped members. The ring detonator results in a flatter wave front per unit length of warhead thereby achieving improved efficiency and the use of a shorter warhead.
