Problems solved by technology

[0005] Aiming at the current problem that adiabatic shear is prone to occur during the collision between the warhead and the target, the purpose of the present invention is to provide a titanium-steel composite warhead shell, which can well overcome the collision between the warhead and the target In the process, the problem of adiabatic shearing is prone to occur, and while improving the penetration performance of the warhead, the mass of the warhead shell is reduced, and the explosive filling ratio of the warhead is improved, thereby enhancing the damage capability of the warhead

Abstract

The invention discloses a titanium-steel composited warhead shell, and belongs to the field of a warhead structure. The warhead shell comprises a penetration part and a main body part, wherein the penetration part and the main body part are connected in an interference fit manner; the penetration part is made from high-strength steel; and the main body part is made from titanium alloy. The warhead shell can overcome the problem very well that when a warhead collides with a target, adiabatic shear easily occurs; the weight of the warhead shell is reduced when the penetration property of the warhead is improved; the charge-weight ratio of explosive materials of the warhead is increased; and further, the damage capacity of the warhead is improved.

Description

technical field [0001] The invention relates to a warhead casing, which belongs to the field of warhead structures. Background technique [0002] The warhead is a special device for the missile to damage the target. It is the only payload of the missile, and it is also the final damage unit that directly executes the combat mission. It is mainly composed of warhead shell, warhead charge, fuze device and safety device. The warhead shell accommodates the charge and connects the fuze, so that the warhead forms an integral structure. In most cases, the warhead shell is also the substrate for the damaging elements. In modern warfare, the main task of the warhead is to attack targets with important strategic value such as ships, airports, and deep fortifications. It is a combat unit with both armor-piercing capability and blasting power. It is mainly used in various weapon systems such as artillery shells, rockets, missiles, and aerial bombs. It is the part of the ammunition t...
