<p>A shaped-charge device (10, 10') includes a case (12) defining an axisymmetrical forwardly-opening cavity (18) uniformly disposed about a central axis (20); an axisymmetrical, homogeneous-material, liner (14, 56) of variable thickness defining a forwardly-opening cavity (22) having a closed apex (24, 57), with the cavity (22) being uniformly disposed within the case (12) about the central axis (20); and explosive material (16) symmetrically disposed between the case (12) and the liner (14, 56). The liner (14, 56) is so shaped that in response to the explosive material (16) being detonated to thereby explode, the liner (14, 56) is progressively collapsed inward by the exploding material to be formed into a fluid jet (42) of the homogeneous liner material that is forwardly expelled at a varying velocity from the case (12) along the central axis (20), with the forward portion of the jet (42) being squeezed from the apex (24, 57) of the collapsing liner (14, 56). The liner (14, 56) is so shaped that bulges are formed in the jet (42) without causing the jet (42) to deviate from the central axis (20).</p> |
