Experimental study on jet forming and penetrating process of parabolically shaped charge

Abstract In order to improve the jet velocity of the traditional conical shaped charge structure, a parabolic shaped charge structure is proposed by increasing the length of the busbar of the shaped charge. The results show that the metal jet formed by the explosion of parabolic shaped charge structure has stable flight performance and deep penetration depth. To this end, the static explosion tests of parabolic, cone and semi-circular shaped charge structures penetrating steel plates were carried out. Under the condition of the same charge and blast height, the explosion damage characteristics of three shaped charge structures on steel plate structures are compared. The perforation diameter of the parabolic and conical shaped energy structure is 20mm, and the perforation diameter of the semi-circular shaped charge structure is 19mm. The penetration depth of the parabolic shaped charge structure is 1.25 times and 1.5 times that of the cone and semi-circular structures, respectively. The results show that the parabolic shaped charge structure has a longer penetration depth than the traditional shaped charge structure.
