Abstract

Abstract: Summing up the theory analysis, simulation calculation and test study, this paper optimized the dual-mode warhead to achieve the conversion of jetting projectile charge(JPC) and jet (JET). It was analyzed the liner collapse situation under single point detonation and annular detonation by the theory, and optimized the shaped charge parameters, such as liner cone, radian radius, thickness and charge height, by the numerical simulation. Then, it obtained the initiation mode and the matching relations of the shaped charge parameters which could get the conversion between JPC and JET. The JPC was formed by single point detonation, and the JET was formed by annular detonation. The liner cone was chosen 80°~100°, the liner radian radius was 0.1 time charge caliber, the liner thickness was designed in accordance with liner cone, and the charge height is 0.9 time charge caliber. Aimed at the optimal structure, the X-ray imaging test was done, and the error between the test and simulation results is within 8%.
