Abstract
The linear shaped charge is shaped charge using V-liner. The shape charge makes high-velocity metal jet in the shape of a rod, and the metal jet used breaking. The linear shaped charge compared with shaped charge is the metal jet in the shape of linear. Therefore, the linear shaped charge is used as means to cutting and breaking solid rocket motor, geothermal scale and etcetera. In this paper, it was a high-speed photography and cut examination, with a shaped charge of the linear and arc. From the result, generation, a flight and the cutting mechanism were examined. And the Linear shaped charge which laminated a metal plate was developed for metal jet of the arbitrary shape. It was tested in a linear, arc and combination model linear shaped charge. The result shows success for the cutting of the steel sheet, steel tube and geothermal scale.
