SPHERICAL SHAPED CHARGE Russian patent published in 2005 - IPC

FIELD: designing of shaped charges.

SUBSTANCE: the spherical shaped charge has an explosive charge made in the form of a hollow ball, the outer spherical surface and the inner spherical space are coated by metal shells, and the blasting means is made in the form of contact pickups and electric detonators taken in equal quantities. They are installed uniformly and symmetrically to the axes of the hollow ball, respectively, flush with the outer metal shell and flush with the outer spherical surface of the explosive charge. The electric lead outs of each contact pickup are connected to the inputs of each group of electric detonators positioned in the ball segment of the explosive charge located diametrically opposite the given contact pickup. Used as contact pickups are piezoelectric transducers, which are installed in the cut-outs or recesses made in the outer metal shell. The contact pickups and electric detonators may be connected in pairs in the form of a monoblock unit.

EFFECT: provided formation of a cumulative jet normally to the surface to be destructed at its any orientation at the moment of impact with the obstacle.
