A shaped charge is a concave metal hemisphere or cone (known as a liner) backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 10 kilometers per second.
Conventional shaped charges are constructed with a charge case, a hollow conical liner within the case, and a high explosive material positioned between the liner and case. A detonator is activated to initiate the explosive material to generate a detonation wave. This wave collapses the liner and a high velocity metallic jet is formed. The jet pierces the well casing and geologic formation, and a slow moving slug is simultaneously formed. The jet properties depend on the charge shape, the energy released, and the liner mass and composition. A Monroe-effect shaped-charge warhead can be expected to penetrate armor equal to 150-250% of the warhead diameter.
