Linear Shaped Charges

Linear Shaped Charges Linear Shaped Charges are explosives enclosed in a seamless metal sheath designed to cut metal or other solid materials. They are fabricated in continuous lengths shaped in the form on an inverted "V".

When detonated, the V-shaped metal liner with explosive core produces a uniform linear cutting action.

At detonation, the focussing of the explosive high pressure wave as it becomes incident on the side wall causes the metal liner of the Linear Shaped Charge to collapse - creating the cutting force as a plasma jet. This high velocity jet impacts the target with pressures exceeding the target's yeild strength and literally pushing the target material to either side of the path of the jet.

The cutting action can be accentuated by controlling the Linear Shaped Charge dimensions and configuration, explosive type and load, liner thickness and continuity.

The liner may be formed using any malleable metal, but is typically copper, alluminium, lead or silver whereby copper is most commonly used. The explosive which is mostly utilized is Hexogen (RDX) or Nitropenta (PETN).
