Low Order Charges

In most EOD and demolition operations, some situations has to avoid high order explosion. Low order detonation or deflagration is target of low order charges. This is a rapid technique as the textbook definition for deflagration is a rapid burning where the pressure at the reaction front never catches the shock wave.

Copper linear shape charge

Linear Shaped Charge (LSC) or Charge Linear Cutting (CLC)  is an explosive powder enclosed in a seamless copper  sheath with continuous explosives lengths shaped in an inverted “V”. When detonated, the V-shaped metal liner with explosive core produces a uniform linear cut. This action, known as “Monroe effect”, can be mastered by controlling the LSC /CLC  dimensions and configuration, explosive type and load, liner thickness and continuity.  This high velocity jet impacts the target with pressures exceeding the target’s yield strength and literally pushes the target material to either side of the path of the jet.

M112 Demolition charge

 

The M112 Demolition Charge with taggant is comprised of a pressed Composition C-4 block wrapped and sealed in Mylar plastic. The M112 includes a pressure sensitive adhesive tape for application to a variety of surfaces. AES produces the M112 for US DoD and approved foreign military, police and commercial customers.

Ballistic Disc

Charge Efah-1

Consists of a dished copper plate attached to one end of an Aluminum tube. When filled with PE or similar explosive and a detonator positioned centrally at the rear, on initiation, the copper disc reverses producing a self forging fragment (slug) penetrating the casing and giving a 90% probability of deflagration. A nominal 20 cm stand off is used with a top attack on a bomb apparently giving best results. For remote delivery the charge can be delivered with built in standoff.

Affect 1

The cutting and burning actions both get performed as a line rupture is achieved.

Affect 2

Large number of splinters will be avoided to dispose off the filling in one step operation.
