[0019] Embodiment 1 like Figure 1 As shown, the present invention provides a multi-stage damage warhead, including a fuze system 1, and a multi-stage damage combat module is arranged on one side of the fuze system 1. The fuze system 1 can realize the phased triggering of the multi-stage damage module, ensuring that the multi-stage damage module is started according to a predetermined plan, and the multi-stage damage combat module can select corresponding damage units for totaling according to different characteristics of the target, so as to achieve efficient damage to hard targets and soft targets.

[0020] The multi-level damage combat module includes a shell, which is made of high-strength alloy or composite material and has good impact resistance, high temperature resistance and corrosion resistance. The shell is equipped with a primary damage unit, a secondary damage unit and a tertiary damage unit, and the secondary damage unit is located between the primary damage unit and the tertiary damage unit. The primary damage unit is used to efficiently damage hard targets, the secondary damage unit is used to damage soft targets, and the tertiary damage unit is used to produce a continuous destructive effect.

[0021] An explosion-proof layer 9 is provided between the primary damage unit and the secondary damage unit and between the secondary damage unit and the tertiary damage unit. The explosion-proof layer 9 can prevent sympathetic explosion, control the explosion range, make the explosion energy as concentrated as possible and efficiently transferred to the target, protect the fuze system 1, and ensure that the fuze system 1 remains functional during the explosion. A first detonating device 4 is provided at the center of the explosion-proof layer 9, and the first detonating device 4 can trigger an explosion when the situation is appropriate according to combat needs.

[0022] The fuze system 1 includes a contact fuze, a delay fuze and an environmental sensing fuze. The contact fuze is connected to the primary damage unit, the delay fuze is linked to the secondary damage unit, and the environmental sensing fuze is connected to the tertiary damage unit. When the warhead contacts the surface of the target, the contact fuze triggers the primary damage unit, which explosively destroys the outer layer of the target and opens a passage to the deep layer. After the primary damage is completed, the delay fuze triggers the secondary damage unit after an appropriate time interval to strike the inner structure of the target. The delay time is determined by the target characteristics or the real-time environment. When the deep structure of the target is destroyed by the secondary damage unit, the environmental sensing fuze detects the environmental characteristics inside the target through sensors and triggers the tertiary damage unit. The damage plan at this stage is dynamically adjusted by the sensor data analysis results to ensure fatal damage to the core area of ​​the target.

[0023] The primary damage unit includes a conical charge cover 2, which is designed to generate energy focusing and is used to efficiently damage hard targets (armored vehicles). The first charge 3 is filled between the explosion-proof layer 9 and the conical charge cover 2 between the primary damage unit and the secondary damage unit. The diameter of the first charge 3 is 80 mm, the height of the charge column is 160 mm, the curvature radius of the cone arc joint part is 10 mm, and the first charge 3 and the conical charge cover 2 are axisymmetric structures.

[0024] The secondary damage unit includes a spherical segment type charge cover 5, which is designed for wide-area blasting and is used to damage soft targets (unarmored vehicles). The explosion-proof layer 9 between the secondary damage unit and the tertiary damage unit and the spherical segment type charge cover 5 are filled with a second charge 10. The radius of the second charge 10 is, the spherical segment curvature of the spherical segment type charge cover 5 is, and the wall thickness of the spherical segment type charge cover 5 is, so as to achieve the maximum penetration depth.

[0025] The third-level damage unit includes an interfering agent 6, which is located between the explosion-proof layer 9 and the shell between the second-level damage unit and the third-level damage unit. The interfering agent 6 can interfere with radar electronics and destroy enemy radar detection. The interfering agent 6 can also generate strong electromagnetic signals in a specific frequency band to cover or disrupt the enemy's communication frequency band. The interfering agent 6 is filled with a high-energy combustion agent 7, which is aluminum-boron powder and is used to produce a continuous destructive effect. The mass ratio of aluminum and boron in the high-energy combustion agent 7 is , in order to improve the combustion efficiency and reduce the initial reaction temperature. A second detonation device 8 is installed inside the high-energy incendiary agent 7, and the second detonation device 8 can ignite the high-energy incendiary agent 7 when the situation is appropriate according to combat requirements.

Design the fuze system 1 to ensure that the triggering sequence of the multi-stage damage module meets the expected damage effect; S4. Evaluate the damage effect and adjust the activation of subsequent multi-stage damage modules.

[0027] Embodiment 1 The structure of the multi-stage damage module for armored targets is as follows: The material of the conical charge cover 2 in the first-level damage unit is titanium alloy and cemented carbide. Titanium alloy has a high strength-to-weight ratio, which can ensure that the conical charge cover 2 has good penetration during explosion. At the same time, cemented carbide material (such as tungsten carbide) is used at the top of the conical charge cover 2 to improve its penetration and wear resistance.

[0028] The material of the spherical-shaped charge cover 5 in the secondary damage unit is high-purity copper. The copper material has good plasticity and can be effectively extended during the explosion to produce a large-scale fragment cloud. The high-purity copper can ensure the uniformity and effectiveness of the fragments.

[0029] The materials of the high-energy combustion agent 7 in the third-level damage unit are aluminum powder (pure aluminum or high-purity aluminum) and boron powder. The composite material of aluminum and boron can generate extremely high heat during the explosion process. Aluminum powder provides combustion energy, and boron powder improves the efficiency of the combustion reaction and produces sustained high temperature.

The steel-aluminum alloy material has a light weight and good impact resistance. Tungsten steel, as a high-hardness material, can enhance the penetration of the charge cover and is suitable for light armored targets.

[0034] The material of the spherical-shaped charge cover 5 in the secondary damage unit is manganese steel, which has good plasticity and strength and is suitable for the wide-area fragments produced by the explosion, and can effectively destroy equipment, ammunition depots, etc. inside underground facilities.

[0035] The material of the high-energy incendiary agent 7 in the third-level damage unit is aluminum powder and boron powder. The composite material of aluminum and boron can produce high temperature and chemical reaction inside the target, continuously destroying core areas such as ammunition depots and fuel storage areas.

[0036] Therefore, the present invention adopts the above-mentioned multi-stage damage warhead and its design method. The fuze system can realize the staged triggering of the multi-stage damage module, ensuring that the multi-stage damage module is started according to the predetermined plan. The multi-stage damage module can select the corresponding damage unit for attack according to the different characteristics of the target to achieve efficient damage to hard targets and soft targets.
