Precision Linear Shaped Charge Designs for Severance of Aluminum Materials

The Precision Linear Shaped Charge PLSC design concept involves the independent fabrication and assembly of the liner wedge of PLSC, the tamper confinement, and explosive. The liner is the most important part of an LSC and should be fabricated by a more quality controlled, precise process than the tamper material. Also, this concept allows the liner material to be different from tamper material. The explosive can be loaded between the liner and tamper as the last step in the assembly process rather than the first step as in conventional LSC designs. PLSC designs are shown to produce increased jet penetrations in given targets more reproducible jet penetration, and more efficient explosive cross sections using a minimum amount of explosive. The Linear Explosive Shaped Charge Analysis LESCA code developed at Sandia National Laboratories has been used to assist in the design of PLSCs
