Abstract

In order to further enhance the damage capability of the explosively formed penetrator (EFP) warhead, a combination of theoretical analysis, numerical simulation, and experimental verification was employed to design a novel explosively formed arrow-shaped penetrator warhead. The formation effect of the explosively formed arrow-shaped penetrator was controlled by adjusting the number of linearly arranged explosive liners, thereby increasing the damage power of the damage element. Initially, theoretical analysis was conducted to establish a physical model, determining the number of liner arrangements. Subsequently, numerical simulations were performed to validate the feasibility of the designed scheme. A warhead with 12 columns of linearly arranged liners was then fabricated and subjected to static detonation experiments. The experimental results demonstrated that a single liner could form two explosively formed arrow-shaped penetrators, capable of penetrating a 30 mm-thick Q235 steel plate at a distance of 5 m. The research findings indicate that the principle of forming explosively formed arrow-shaped penetrators from linear liners is viable and holds significant implications for the design of EFP warheads.

Key words： warhead; explosively formed; flechette penetrator
