Abstract
Abstract A shaped charge having plane sides surfaces, in which a booster charge is arranged above a main or primary explosive charge, and wherein the booster charge extends from one of the side surfaces to the oppositely located surface. The booster charge is constituted of an explosive whose detonation velocity is higher than that of the explosive material of the main explosive charge. Thus, when the booster charge is detonated from one side surface thereof, then the booster charge has detonated across the entire length which is present between the two side surfaces, prior to the detonation wave within the main explosive charge having traveled across the entire length thereof.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
112 words
In a chain of shaped charges consisting of a plurality of charges in which each charge has plane side surfaces, including a booster charge positioned above a main explosive charge, said booster charge extending from one side surface to the oppositely located side surface; the improvement comprising: said booster charge being constituted of an explosive material having a detonation velocity higher than that of the explosive material of the main explosive charge, the detonation velocity of the booster charge being at least by about 8% higher than the detonation velocity of the main explosive charge, and wherein the booster charge extends as a unitary component across said plurality of main explosive charges.
