摘要： A detonation wavefront controller for a linear shaped charge, comprising a first part and a second part. The first part comprises: a detonator holder, and a first aperture having a first width and a shape which is substantially a cyclic polygon, substantially an ellipse or substantially circular. The second part comprises: a second aperture having a second width larger than the first width. With the first part at least partly received within the second part, the first part is moveable relative to the second part to configure the detonation wavefront controller at least between: a first configuration with a first distance between the first aperture and the second aperture, and a second configuration with a second distance between the first aperture and the second aperture, the second distance larger than the first distance.

摘要： Examples relate to a mounting device for an explosive charge, comprising a first layer comprising a first foam material, and a second layer comprising a second foam material. The first layer comprises a first surface for facing a target and a second surface adjoining the second layer. The second layer comprises a recess for receiving at least one of the explosive charges.

摘要： A linear shaped charge comprising a body comprising a foam material, a first explosive element, a second explosive element, a liner and a channel at least partly between the first explosive element and the second explosive element. A related structure is also described, with a first cavity configured to receive a first explosive element and a second cavity configured to receive a second explosive element.

摘要： A frame for a linear shaped charge. In examples, the frame comprises: a first plate having a first surface; and a second plate having a second surface. The frame is configurable between an un-collapsed state and a collapsed state. In the un-collapsed state, there is a void for receipt of explosive material, with the first surface as a first side of the void, the second surface as a second side of the void, and the first surface angled relative to the second surface by an angle within the void of greater than 180°. In the collapsed state the void is at least partly collapsed.

摘要： Examples relate to a linear shaped charge support structure configured to support a linear shaped charge in a canted configuration with at least part of the linear shaped charge canted about a longitudinal axis of the linear shaped charge. Examples relates to a linear shaped charge, the linear shaped charge support structure comprising a linear shaped charge, and a support frame comprising the linear shaped charge support structure and a non-linear shaped charge support structure.
