Studies on a shaped charge jet and the jet sensitivity of explosives

A shaped charge with steady energy output was developed to study all kinds of the explosives sensitivity to shaped charge jets, and its stability was validated by three methods. The jet sensitivities of such explosives as TNT, Comp B, and JB-B were experimentally evaluated by using the standard shaped charge. The obtained result is consistent with that from literature. The relationship between the velocity of jet head and the cover thickness was determined, and the experimental formula was obtained.
