An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance. As the name suggests ...

Numerical and experimental simulation are combined to compare and analyze the forming process and penetration performance of explosively formed projectile (EFP) in DLSC and ordinary shaped charge (OSC).

2014年6月1日 · The ultimate goal of weapon system employing an explosively formed penetrator (EFP) is to defeat a target at the longest standoff. In order to do this, an EFP must be aerodynamically stable so as to strike the target at a small angle of obliquity, and the decay velocity per meter of EFP must be smaller at extended standoff.

2022年1月1日 · A new type of annular shaped charge was utilized to enhance penetration performance into underwater structures in this paper. Explosive Formed Projectile (EFP) which can be formed by a shaped charge with a spherical segment liner was proved having a stable flight at a large stand-off distance and causing a large penetration diameter into ...

2022年10月1日 · The study found that the shape of the EFP was main affected by the shape and material of the liner, the type and detonation method of the explosive, the structure and geometric parameters of the shaped charge.

2011年1月1日 · EFP generates a larger and slower projectile with reduced penetration potential. They have emerged militarily in the form of EFP-IED used by irregular forces. Despite limited published data, EFP-IEDs appear to inflict catastrophic fragmentation injury to those caught in the trajectory and minor injury to those outwith.

2017年6月12日 · Explosively Forged Penetrator (EFP) Warhead. A shaped charge is a concave metal hemisphere or cone (known as a liner) backed by a high explosive, all in a steel or aluminum casing.

2019年4月8日 · This study aimed to investigate the interference of explosive reactive armor (ERA) on the penetration capability of explosively formed projectiles (EFPs). A numerical simulation model of EFP and the ERA interaction system was established. Flash X-ray experiments for observing the interaction between EFP and ERA were performed.

2017年6月3日 · The explosively formed projectile (EFP) has been widely used in shaped-charge warheads owing to its advantage of a large standoff post-penetration effectiveness [1, 2]. The EFP is launched at a considerable distance from its target and thus requires an aerodynamic shape, long-range flight stability, and targeting accuracy [ 3 ].

Explosively formed projectile (EFP) has advantages of insensitive to the height of explosion, small interference from reactive armor and large penetration diameter. In this paper, a Ta based dual...
