Abstract
Description
Technical field: The present invention relates to the technical field of ammunition, in particular to a fully energetic warhead. Background technology: The warhead is the determining component for the ultimate value of explosives. The shaped charge warhead is the most common type of warhead, and can be divided into armor-piercing warheads and assault warheads according to the target type. For shaped charge warheads, their killing radius, penetration depth, and aftereffects determine the missile's destructive effectiveness. However, existing assault warheads use inert charge caps, which do not contain lethal elements after explosion. After the jet passes through the reinforced concrete target wall, it has no ignition effect on oil or ammunition, and the damage form is single. Summary of the invention: The present invention provides a fully energetic warhead to overcome the deficiencies in the prior art.
[0004] This application provides the following technical solutions: A full-energy warhead comprises a shell, wherein the shell is filled with a charge, a charge liner is arranged in the shell on one side of the charge, a pressure screw is threadedly connected to one side of the charge liner, and the charge liner is pressed against one side of the charge by tightening the pressure screw. The invention is characterized in that a through hole is arranged on the shell on the other side of the shell, a fuze covering the through hole is connected to the outer wall of the shell, one side of the fuze is in contact with the charge, and the shell and the charge liner are made of high entropy alloy.

[0010] Advantages of the invention: The invention has a simple structure and is easy to manufacture. It increases the initial energy of the warhead without increasing the weight and size. After the warhead explodes, the energetic rod-type jet formed can form overpressure, ignition and detonation effects after passing through obstacles. On the other hand, the detonation wave drives the energetic shell and the rear cover to break and scatter, killing people in front of the obstacle and producing ignition and detonation effects.
