| Research Abstract |
The Linear shaped charge used PETN for an explosive. And it used metal thin wire explosion by the transferring energy from the capacitor to the shock wave for initiating. 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. The metal jet shape and performance by the initiating position was examined. 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 removal of the geothermal scale.
