Oil shaped charge for deeper penetration

摘要

An oil shaped charge for deeper penetration includes a case, a quantity of explosive material, and a liner. The case is designed with different inner surface sections, where the step inner surface section creates maximum space for the explosive material so that the explosive material can be effectively placed between the case and the liner. A step conical region of the liner, a step conical inner surface of the case, and an effective placement of the explosive material are able to achieve significantly higher speeds for liner materials flow into the jet, thus creating deeper penetration.

1. An oil shaped charge for deeper penetration comprises:
a case; a quantity of explosive material; a liner; the case comprises a first conical inner surface, a second conical inner surface, a step conical inner surface, a third conical inner surface, and a fourth conical inner surface; the liner comprises a tip conical region, a front conical region, a rear conical region, and a step conical region; the case and the liner being radially positioned around a central axis; the liner being coaxially mounted within the case along the central axis and offset from an inner surface of the case; the step conical inner surface being adjacently positioned around the step conical region; the quantity of explosive material being radially interposed between the case and the liner; the step conical inner surface, the third conical inner surface, and the fourth conical inner surface each comprise a first edge and a second edge; a third radial distance being extended from the second edge of the second conical inner surface and the first edge of the step conical inner surface to the central axis; a fourth radial distance being extended from the second edge of the step conical inner surface and the first edge of the third conical inner surface to the central axis; the fourth radial distance being greater than the third radial distance; an average wall thickness of the liner being extended between an outer surface and an inner surface of the liner; the average wall thickness of the rear conical region being greater than the average wall thickness of the tip conical region; the wall thickness of a rear end for the front conical region and the average wall thickness of the rear conical region have a ratio of 0.10 through 0.99; a step width being extended from a first rim of the step conical region to a second rim of the step conical region along the central axis; and an overall length being extended from an apex end of the tip conical region to a rim of the rear conical region along the central axis rear conical region along the central axis; and the step width being ranged between 0.01 of the overall length to 0.7 of the overall length.
