Abstract
Description
Technical Field
[0001] The invention belongs to the field of ammunition, and in particular relates to an active anti-interception warhead which effectively utilizes charge space. Background Art
[0002] In modern warfare, the transportation of personnel, the carrying of warheads, and the detection of combat environments rely heavily on light armored vehicles. Therefore, whether light armored vehicles can be effectively destroyed greatly affects the direction of the war. With the continuous development of radar detection systems, warhead interception technology has become very mature. At present, under complex battlefield conditions, it is no longer the power of the warhead that affects the damage effect, but the application of anti-interception technology. In recent years, with the in-depth study of explosively formed projectiles (EFP), scientists have discovered that the forming of EFP projectiles does not always require traditional rear shells and cylindrical charges. Studies have shown that the effective charge is often less than the traditional cylindrical charge. This discovery provides new ideas for the design and optimization of EFP ammunition.
[0003] The existing EFP warhead plays a relatively single role in complex battlefield combat environments, and it is difficult to carry out targeted killing of enemy detection systems or personnel. The precise strikes of the interception system also make it difficult for the EFP warhead to play its due destructive role. Summary of the invention
[0004] The purpose of the present invention is to provide an active anti-interception warhead design scheme that effectively utilizes the charge space, effectively utilizes the charge space while improving the active anti-interception capability of the warhead, and effectively destroys the enemy's detection system to protect our EFP warhead to complete the established combat mission.
[0005] The technical solution to achieve the purpose of the present invention is:
[0006] An active anti-interception warhead that effectively utilizes charge space, comprising:
[0007] The EFP liner is located at the front end of the main warhead;
[0008] The main warhead has a cross-sectional area that gradually increases from the bottom along the axis to the front, and the rear space is used to install a directional killing warhead;
[0009] There are multiple directional killing warheads, which are arc-shaped plate structures and are evenly distributed at the rear of the main warhead along the circumferential direction;
[0010] The ignition and launching device is arranged at the rear end of the directional killing warhead, and is used to perform secondary acceleration on the separated directional killing warhead, so that the directional killing warhead is located ahead of the main warhead and attacks the enemy unit;
[0011] An ejection device is arranged between the main warhead and the directional lethal warhead, and is used to eject the directional lethal warhead after the restraint is released so as to separate the directional lethal warhead from the main warhead;
[0012] The warhead shell adopts a multi-petal windage detachment shell to restrain the directional killing warhead;
[0013] Electromagnet, used to fix the multi-petal warhead casing when powered.
[0014] Compared with the prior art, the present invention has the following significant advantages:
[0015] (1) The cross-sectional area of the rear shell and charge of the EFP warhead is gradually increased from the bottom along the axial direction, which reduces the amount of charge used and saves tail space without affecting the EFP effect.
[0016] (2) On the premise that the tail space is saved, an ejection device is installed on the outside of the main warhead shell and multiple arc cylindrical directional killing warheads are connected to effectively utilize the warhead space.
[0017] (3) The warhead of the present invention achieves high utilization of charge space and has an active anti-interception effect. The small directional killing warhead it carries can effectively resist the enemy's interception system, and protect the safety of the rear main warhead through multiple ejection directional killing warheads in different postures.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] like Figure 1-2 As shown, an active anti-interception warhead of this embodiment that effectively utilizes the charge space includes an EFP liner 1, an ejection device 2, a main warhead 3, a directional killing warhead 4, an ignition and launch device 5, and a warhead shell 6. The active anti-interception warhead has two postures, namely, a combat posture such as Figure 1 And untriggered gestures such as Figure 2 .
[0024] The EFP charge liner 1 is arranged in front of the main warhead 3. The EFP charge cross-sectional area of the main warhead 3 gradually increases from the bottom along the axial direction to the front. Without affecting the EFP effect, the charge usage is reduced and the tail space is saved for the installation of the directional killing warhead 4.
[0025] The main structure of the ejection device 2 is a two-stage spring. Both of the two-stage springs are welded to the outside of the main warhead 3 shell, arranged between the main warhead 3 shell and the directional killing warhead 4, and only one end is connected to the main warhead 3 shell. Each directional killing warhead 4 is provided with an ignition and launching device 5 at the rear end. The length of the rear-stage spring is greater than that of the front-stage spring, so that the angle between the directional killing warhead 7 and the central axis of the main warhead 3 after deployment is 10°, and the directional killing warhead 7 is forward-leaning.
[0026] The directional killing warhead 4 is an arc-shaped plate-like structure. A plurality of directional killing warheads 4 are evenly distributed at the rear of the main warhead 3 along the circumferential direction. A multi-petal warhead shell 6 is provided outside the directional killing warhead 4. The multi-petal warhead shell 6 is assembled into a cylindrical structure with a closed front end. An electromagnet 7 is provided at the front of the multi-petal warhead shell 6 for constraint. The two-stage spring is in a compressed state under the action of the warhead outer shell 6. In the compressed state, all directional killing warheads 4 are contracted inside the warhead. In the untriggered posture, the electromagnet 7 is in an energized state, and the warhead shell 6 is in a fixed state under the action of the electromagnet 7. The warhead shell 6 is fastened to the outside of the main warhead 3 and the directional killing warhead 4. When the combat posture is triggered, the electromagnet 7 is powered off, and the warhead shell 6 automatically falls off under the action of wind resistance. The spring pops out, and under the synergistic action of the two-stage spring, the warhead is adjusted to be ejected at an angle of 10° between the directional killing warhead 7 and the central axis of the main warhead 3. After 0.2s, the tail ignition device 5 ignites and accelerates, causing the directional killing warhead 7 to accelerate and attack the enemy unit.
[0027] The ejection device 2 adopts a two-stage spring design, in which the spring coefficient of the front stage spring is later than the spring coefficient of the lower stage spring, and the original length of the front stage spring is shorter than the original length of the rear stage spring. In the compressed state, the directional killing warhead 4 is closely attached to the two-stage spring inside, and closely attached to the warhead shell 6 of the split-type wind resistance detachment outside. After the warhead shell 6 of the split-type wind resistance detachment falls off, the two-stage spring pops out and restores its original length. The length and spring coefficient of the two-stage spring are different. Under the synergistic effect of the two-stage spring, the directional killing warhead is adjusted to be ejected at an angle of 10° with the central axis of the main warhead. The directional killing warhead 4 is designed in an arc plate shape with a narrow front and a wide rear, and the angle between the width (end face) of the left and right ends is 50°. Six directional killing warheads are placed around the tail space of the warhead 3 to make full use of the charge space. Multiple directional killing warheads 4 are launched simultaneously, which greatly reduces the interception probability of the interception system. In addition, an ignition and launching device 5 is installed at the tail of the directional killing warhead 4. When the combat posture is adjusted, the ignition and launching device 5 is triggered after 0.2s, and the directional killing warhead 4 is accelerated for the second time. The main warhead EFP is located behind the directional killing warhead 4 to reduce the probability of being intercepted.
[0028] The warhead shell 6 adopts a multi-petal windage drop-off shell (the principle is the same as the bullet support), adopts a windage automatic drop-off shell design, is concave inside and convex outside, and is composed of three windage drop-off shells. The electromagnet 7 is in an energized state before being triggered to fix the petal windage drop-off shell.
[0029] The combat method is as follows:
[0030] This warhead is installed in the missile and approaches the enemy's armored vehicle through the missile launcher and guidance device. An interception detection device is installed at the front end of the missile. When our warhead is locked by the enemy's radar detection system or is a certain distance away from the enemy's armored vehicle, the interception detection device sends an electrical signal to the electromagnet, and the electromagnet changes from a passage to an open circuit. The petal-type wind resistance shedding shell loses its fixing device and falls off under the influence of wind resistance, and the spring pops out.
[0031] When the spring 2 pops out, the directional killing warhead 4 is ejected at an angle of 10° to the central axis of the main warhead under the action of the two-stage spring. Then 0.2s later, the ignition and launching device 5 at the tail of the directional killing warhead 4 is started. The directional killing warhead 4 quickly approaches the enemy detection system under the acceleration of the tail ignition device. At this time, the EFP main warhead maintains the original firing rate, and the multiple small directional killing warheads launched in front are accelerated by the ignition device to approach and destroy the enemy interception system, protecting the rear EFP main warhead to complete the established combat mission.
[0032] Due to the large number of directional killing warheads, and the fact that they are launched at an angle of 10° to the central axis of the main warhead and are accelerated secondary by the ignition device, it is difficult for the enemy's detection system to intercept them all, increasing the enemy's interception difficulty and protecting the main warhead at the rear to safely complete the established combat mission.
