Abstract
A warhead (10) configuration for forming a large-diameter hole through a wall of a target includes a shaped charge of explosive material (12) presenting an annular front surface portion (16) circumscribing an axis of the charge. The annular front surface portion (16) exhibits a concave profile as viewed in cross-section through the axis, at least part of the concave profile being configured such that a vector projecting outward from the part normal to the annular front surface portion diverges from the axis. A liner (14) is provided adjacent to at least part of the annular front surface portion.
Claims17
A warhead configuration for forming a large-diameter hole through a wall of a target, the warhead configuration comprising:
- (a) a charge of explosive material, said charge having an axis and presenting an annular front surface portion circumscribing said axis, said annular front surface portion being configured so as to exhibit a concave profile as viewed in a cross-section through said charge passing through said axis, at least part of said concave profile being configured such that a vector projecting outward from said part normal to said annular front surface portion diverges from said axis, said concave profile turning through no more than 90°, wherein said concave profile corresponds substantially to an arc of a circle, said arc subtending an angle of between 15° and 90° to a center of curvature of said arc;
- and
- (b) a liner adjacent to at least part of said annular front surface portion, wherein said charge and said liner are configured such that, when said charge is detonated, material from said liner is formed into an expanding explosively formed ring.
A warhead configuration for forming a large-diameter hole through a wall of a target, the warhead configuration comprising:
- (a) a charge of explosive material, said charge having an axis and presenting an annular front surface portion circumscribing said axis, said annular front surface portion being configured so as to exhibit a concave profile as viewed in a cross-section through said charge passing through said axis, at least part of said concave profile being configured such that a vector projecting outward from said part normal to said annular front surface portion diverges from said axis, said concave profile turning through no more than 90°, wherein said annular front surface portion corresponds to at least about 80% of the total front surface of said charge as viewed parallel to said axis;
- and
- (b) a liner adjacent to at least part of said annular front surface portion, wherein said charge and said liner are configured such that, when said charge is detonated, material from said liner is formed into an expanding explosively formed ring.
