Fundamental jet performance tests of linear shaped charges (LSC) were conducted to evaluate their jet penetration. The purpose of these tests is to enhance the penetration performance of LSC. The apparatus used for these tests were based on penetration tests for conical shaped charges (CSC). Photos of the aluminum-sheathed LSC jet taken by using flash X-ray confirmed the jet velocities to be about 2,400m/s. The velocity was also verified by the AUTODYN-2D code, and was an unexpected figure as compared to CSC. The penetration velocities of aluminum- and lead-sheathed LSC against steel plates were calculated to be less than 1,000m/s at a maximum region.
