Description

Technical Field

[0001] This invention belongs to the field of ammunition, specifically relating to a cross-media reconnaissance and strike integrated "flying fish" biomimetic ammunition. Background Technology

[0002] Modern warfare is more likely to involve localized conflicts, requiring large quantities of specialized munitions for special missions. In recent years, with the emergence of biomimetic munitions, possessing superior capabilities not found in conventional munitions, they are poised to lead a new wave in munitions development. Humans utilize the characteristics of certain organisms to enhance and improve the capabilities of equipment, enabling it to conceal itself in complex environments. Besides targeting specific individuals, this allows for close-range intelligence and surveillance missions.

[0003] A cross-medium aircraft is a new concept aircraft that can both strike targets in the air and conceal itself underwater. It combines the high maneuverability of an aircraft with the stealth of a submarine, which can improve environmental adaptability and expand application scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a cross-media reconnaissance and strike integrated "flying fish" bionic munition design scheme to improve the survivability and penetration capability of bionic munitions, so as to make them have both structural destructive force and personnel killing capability.

[0005] The technical solution to achieve the purpose of this invention is as follows: a cross-medium reconnaissance and strike integrated "flying fish" biomimetic munition. The biomimetic munition is generally flat and spindle-shaped, including an aerodynamic body and a head shell weakly connected to the aerodynamic body. The head shell contains a composite damage warhead. The aerodynamic body contains a projectile charge for ejecting the composite damage warhead. Retractable main wings and ailerons are symmetrically arranged on both sides of the aerodynamic body from front to back. A tail fin is provided at the tail of the aerodynamic body. The composite damage warhead forms an EFP penetrating jet and fragmentation damage unit.

[0006] Furthermore, the head shell is connected to the pneumatic body via explosive bolts.

[0007] Furthermore, the main wing has a swept leading edge.

[0008] Furthermore, the plane containing the caudal fin is perpendicular to the water surface, and the caudal fin is an asymmetrical V-shape, with the upper side of the asymmetrical V-shape being shorter than the lower side.

[0009] Furthermore, the composite damage warhead is cylindrical in shape and includes a fragmentation shell, an outer charge, a shaped charge liner, an auxiliary charge, a central shell, an inner charge, and a central adhesive-bonded interlocking buckle.

[0010] The internal charge is contained inside the central shell, which is conical in shape. Inside the central shell is a propellant liner, and the propellant and the propellant together form an EFP penetrating jet. An auxiliary charge is provided on the outer circumference of the central shell.

[0011] The fragmentation shell is multi-lobed, and each fragmentation shell contains an external explosive charge. The shape of the external explosive charge matches the shape of the outer surface of the central shell. After the ends of the multi-lobed fragmentation shells are locked by a central adhesive fastener, the composite damage warhead is cylindrical in shape.

[0012] Furthermore, the central shell and the shaped charge shroud are connected by a hinge.

[0013] Furthermore, the fragment shell rotates freely in the radial direction, with a maximum unfolding angle of 90°.

[0014] A method for combat using the aforementioned biomimetic munitions includes the following steps:

[0015] Step (1): When an enemy threat is detected in the sea area, the required number of "Flying Fish" bionic munitions are deployed by submarines or ships; the munitions move towards the target sea area through cross-medium movement, and when they reach the target sea area, they use their bionic shape to conduct close-range reconnaissance of the target.

[0016] Step (2): When the ammunition receives the attack command, it switches to attack mode, approaches the target to destroy it, and the explosive bolt and ejection charge detonate in succession to eject the composite damage warhead from the inside. The ammunition in front first uses the shaped charge function of the warhead to detonate the internal charge located in the central shell, and interacts with the shaped charge liner to form an EFP shaped charge jet, which penetrates the armor of the target through the EFP shaped charge jet.

[0017] Step (3): When the target's armor is damaged to form a gap, thereby exposing the internal facilities, the munitions that enter through the gap first detonate the auxiliary charge, and the impact center glued and fixed the locking buckle to make the fragment shell unfold at a fixed angle. Finally, the inner and outer charges are detonated to achieve large-scale damage to the target.

[0018] Furthermore, in step (2), when encountering enemy interception, the main wing and aileron are contracted to reduce the drag of the cross-medium when encountering underwater interception, and the main wing and aileron are re-deployed after entering the air medium to increase lift and stability and improve gliding distance; when encountering air interception, the main wing and aileron are contracted to reduce the impact force of the cross-medium when entering the air medium.

[0019] Compared with the prior art, the significant advantages of this invention are:

[0020] (1) A new concept aircraft that can glide in the air and dive underwater; the cross-medium characteristics enable the biomimetic munition to switch between air and sea operation modes at will, making it difficult for the enemy to detect it. On the other hand, its good maneuverability gives it excellent penetration capability, greatly improving the efficiency of penetration attack.

[0021] (2) This invention makes full use of the principles of bionics; the aerodynamic shape of the ammunition imitates the shape of a flying fish, taking into account the requirements of aerodynamics and hydrodynamics, while the bionic shape can also confuse the enemy's reconnaissance equipment.

[0022] (3) The warhead of the present invention achieves multiple functions and uses. Its EFP shaped charge composite warhead has both structural destructive force and personnel killing capability; at the same time, the environment in which it performs its missions is greatly extended compared with traditional single-medium munitions, reducing mission costs and improving completion efficiency.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, a cross-media reconnaissance and strike integrated "Flying Fish" biomimetic munition includes an explosive bolt 1, an aerodynamic main body 2, a tail fin 3, ailerons 4, main wings 5, a head shell 6, a projectile charge 7, a fragmentation shell 8, an external charge 9, a shaped charge liner 10, an auxiliary charge 11, a central shell 12, an internal charge 13, and a central adhesive-bonded fastener 14. This biomimetic munition has two motion states: underwater submersion and aerial gliding, enabling cross-media maneuverability and possessing both reconnaissance and strike capabilities. The platform is equipped with a shaped charge fragmentation composite warhead, possessing both structural destructive force and personnel lethality.

[0030] The biomimetic munition body is characterized by comprising a pneumatic body 2, a head shell 6, explosive bolts 1, and a ejector charge 7, which, together with the composite damage warhead, constitute the biomimetic munition. The pneumatic body 2 and the head shell 6 are connected by two explosive bolts, facilitating the installation and ejection of the warhead. When the composite damage warhead needs to be ejected, the ejector charge 7 detonates, propelling the warhead and impacting the explosive bolts, which shear it off, thus separating the pneumatic body 2 from the head shell 6 and ejecting the composite damage warhead into the "Flying Fish" biomimetic munition.

[0031] The biomimetic munition's main body is a flat, spindle-shaped structure, balancing aerodynamic and hydrodynamic requirements. The main wings on both sides have swept-back leading edges. The tail is an asymmetrical (relative to the horizontal plane, the plane of symmetry for the flying fish is defined as the vertical plane, and the plane perpendicular to the vertical plane is defined as the horizontal plane) V-shaped tail fin. The ailerons are located in the lower middle-rear section, at a certain angle to the horizontal plane, providing lift and improving lateral stability during gliding. During medium movement, the drag across the medium is reduced by retracting the main wings and ailerons. Since their cross-sectional areas gradually decrease, the retraction of the main wings and ailerons is achieved by a motor-driven screw rotation that rotates and extends / retracts in stages.

[0032] The composite damage warhead consists of a shaped charge liner 10, a casing (divided into four petal-shaped fragmentation casings 8 and a central cone-shaped central casing 12), an internal explosive charge 13, an external explosive charge 9, and an auxiliary explosive charge 11. The central casing 12 has four hinges on the side closest to the shaped charge liner 10, which can hinge the four fragmentation casings 8 to the central casing 12. The fragmentation casings 8 can rotate freely in the radial direction, achieving axial deployment. The fragmentation casings 8 have a fixed-angle deployment function, mainly achieved by the central adhesive-bonded fastener 14 located on the overall axis of the ammunition when the four fragmentation casings 8 are closed, which is bonded and fixed through the central connection area of ​​the four fragmentation casings 8. The mechanical limit is reached by detonating the auxiliary explosive charge 11, which impacts the central adhesive-bonded fastener 14.

[0033] The internal charge 13 is located inside the central shell 12 and is used to interact with the shaped charge liner 10 to form an EFP penetrating jet. The external charge 9 is distributed on one side of the four fragmentation shells 8 to form fragmentation damage units. The auxiliary charge 11 is attached to the conical surface of the central shell 12 and is used to detonate the auxiliary charge 11 before the internal charge 12 is detonated by activating the detonation trigger signal source of the auxiliary charge 11, which is made of piezoelectric material. The impact is then fixedly fastened by the central adhesive latch 14 to cause the fragmentation shells 8 to unfold at a certain angle.

[0034] The combat methods are as follows:

[0035] When an enemy threat is detected in a certain sea area, a certain number of "Flying Fish" bionic munitions can be deployed in large quantities by submarines or ships.

[0036] The "flying fish" moves rapidly toward the target sea area through cross-medium motion.

[0037] When the "flying fish" reaches the target sea area, it can use its biomimetic shape to conduct close-range reconnaissance of the target.

[0038] When the "Flying Fish" receives an attack command, it switches to attack mode. When encountering enemy interception, it can break through defenses through cross-medium means. If it encounters underwater interception, it can leap up to evade, reduce cross-medium drag by retracting its main wings and ailerons, and then re-deploy its main wings and ailerons after entering the air medium to increase lift and stability, thereby increasing gliding distance. If it encounters aerial interception, it can dive into the water and reduce the cross-medium impact by retracting its main wings and ailerons.

[0039] When the "Flying Fish" approaches the target to cause damage, the explosive bolts on the outside and the propellant inside the "Flying Fish" detonate in sequence, ejecting the shaped charge warhead from inside the "Flying Fish". The "Flying Fish" in front first uses the shaped charge function of the warhead to detonate the internal charge in the central shell, which interacts with the shaped charge liner to form an EFP shaped charge jet, which penetrates the target's armor.

[0040] Once the target's armor is breached, exposing its internal components, the Flying Fish that enters through the breach first detonates the auxiliary charge attached to the conical surface of the composite damage warhead. This impacts the central locking mechanism, causing the fragmentation shell to unfold at a fixed angle. Finally, the internal and external charges detonate, resulting in widespread damage to the target.
