ABSTRACT:
The invention is a shaped charge comprising a housing, a liner, a quantity of explosive inside the housing between the housing and the liner, and a retaining spring in contact with the liner and the housing. The retaining spring is positioned to retain the liner substantially immovably inside the housing and has compressed external dimensions to enable locking engagement with the housing. The retaining spring provides axial force against the liner to compress the explosive and prevent shifting and settling of the explosive. The retaining spring also exerts laterally outward force against the circumference of the liner to reduce effects of thermal contraction on the liner. In the preferred embodiment, the retaining spring comprises a bellville spring. The bellville spring has an internal diameter substantially the same as the maximum diameter of the liner to prevent interference with discharge of the detonating shaped charge.
