Title: COLLAPSIBLE FRAME AND LINEAR SHAPED CHARGE
Abstract:
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 180º. In the collapsed state the void is at least partly collapsed.
