Abstract
A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising a charge of explosive material and a liner. The charge The front surface includes two annular front surface portions, portion, circumscribing the axis. Each of the annular front surface portions is configured so as to exhibit a concave profile as viewed in a cross-section through the charge parallel to the axis. The liner includes a first liner disposed adjacent to the inner annular portion and a second liner disposed adjacent to the outer annular portion such that, when the charge is detonated, material from the first liner is formed into a first expanding explosively formed ring and material from the second liner is formed into a second explosively formed ring.
Claims21
A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising:
- (a) a charge of explosive material, said charge having an axis and a front surface, said front surface including two annular front surface portions circumscribing said axis, one of said annular front surface portions being an inner annular portion, another of said annular front surface portions being an outer annular portion, said inner annular portion being disposed between said axis and said outer annular portion, each of said two annular front surface portions being configured so as to exhibit a concave profile as viewed in a cross-section through said charge parallel to 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;
- and
- (b) a liner including a first liner disposed adjacent to at least part of said inner annular portion and a second liner disposed adjacent to at least part of said outer annular portion, such that, when said charge is detonated, material from said first liner is formed into a first expanding explosively formed ring and material from said second liner is formed into a second expanding explosively formed ring.
A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising:
- (a) a charge of explosive material, said charge having an axis and presenting a front portion;
- and
- (b) a liner disposed adjacent to at least part of said front portion, wherein said charge and said liner are configured such that, when said charge is detonated, a majority of material from said liner forms two expanding explosively formed rings.
