Description

Technical Field

[0001] The present invention relates to the technical field of structural mechanics and explosion mechanics, and in particular to a one-machine, multiple-missile, returnable low-altitude strike device based on an explosive transmission network and a method thereof. Background Art

[0002] As the curtain of developing low-altitude economy slowly opens, the uses of drones in the economic and military fields have also been widely explored. While benefiting mankind, drones may attack personnel or certain important buildings and facilities if they lose control or are manipulated by humans, affecting national security and social stability. Therefore, it is urgent to develop drone countermeasure technology.

[0003] Physical capture is one of the important ways to counter drones. Firepower weapons can be used to attack drones. Rockets, ground-based light missiles, and air-to-air light missiles can achieve destructive strikes on target drones. Generally, such devices can be used in the peripheral areas of more important large-scale activities to implement emergency countermeasures and strikes on important suspicious drones. However, such interception and strike devices are expensive and pose potential safety risks to ground targets. They should be used with caution in non-emergency situations.

[0004] In addition, most of these strike methods carry out attacks or counterattacks at a distance of hundreds of meters or even farther from the drone. The strike accuracy and counterattack effect are affected by the control accuracy of the launch equipment, energy consumption, weather and other factors, and the final strike effect cannot be guaranteed.

[0005] In recent years, there have been technologies that use small drones to drop explosives on fixed targets or conduct suicide attacks. However, there have been no reports on technologies that use drones to carry ammunition to attack and damage drones. In addition, there is an irreconcilable contradiction between the accuracy and power of attacks on enemy aircraft and the reusability of one's own drone platform.

[0006] When facing mobile targets such as drones, the carrier drone is often closer to the explosives than the target. If the amount of explosives is insufficient, the destructive effect on the enemy will be insufficient. When the amount of explosives increases to a certain level, the carrier drone will be damaged first and unable to return, and the cost of the attack is extremely high. Summary of the invention

[0007] The purpose of the present invention is to provide a low-altitude strike device with multiple missiles and return capability based on a transmission network and a method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions: A multi-missile returnable low-altitude strike device based on a detonating network, including a drone carrier pendant and a launch panel. A connecting member is vertically installed at the top of the drone carrier pendant, and a launch base is connected to the bottom of the drone carrier pendant. The launch panel is installed on the launch base, and the surface of the launch panel is filled with projectiles and explosives respectively. A connecting seat is arranged on one side at the bottom of the launch base, and a fixing seat is arranged on one side of the launch base.

[0009] Further, a detonating network charge groove structure that can be vertically and horizontally connected for filling explosives is provided on one side surface of the launch base, and a projectile launch hole structure for filling projectiles is also provided on one side surface of the launch base.

[0010] Further, the whole of the launch panel is fitted and embedded into the central part of the interior of the launch base, and the launch base and the drone carrier pendant are movably connected.

[0011] Further, an interface structure for connecting with the abdomen of the drone is provided at the top end of the connecting member, and a jack structure for connecting with the abdomen of the drone by using a movable push pin structure is provided at the upper end of the connecting member.

[0012] Further, an output hole structure is provided at the staggered position of the charge groove structure on the surface of the fixing seat for filling pyrotechnics. One projectile on the surface of the launch base corresponds to one output hole structure on the surface of the launch base, and the charge groove structure on one side surface of the launch base is arranged in a square, circular or trapezoidal structure.

[0013] Further, the pyrotechnics and explosives are made of explosives such as JO type, JH type, HNS or detonating charges. The explosives are filled into the grooves on the surface of the launch panel by precision pressing, extrusion or casting processes for powder explosives or slurry explosives. The projectiles are fixed inside the projectile launch hole structures on the surface of the launch panel by adhesives. The shapes of the projectiles include spheres, cylinders, frustums of cones and cones, and the materials are made of titanium alloy, tungsten alloy, steel, etc.

[0014] Further, the launch base and the launch panel are fixedly connected by bolts, and the launch base and the connecting seat are fixedly connected.

[0015] Further, the drone carrier pendant and the fixing seat are integrally structured, and the fixing seats and the connecting seats are connected to each other by using a movable push pin structure.

[0016] The present invention provides a multi-missile returnable low-altitude strike device based on a detonating network and its method, having the following beneficial effects:

[0017] 1. In the present invention, a number of projectiles are filled in the side elevation of the launch panel. At the same time, the projectiles are set in structural shapes such as spheres, cylinders, frustums of cones, and cones, and the projectiles are made of titanium alloy, tungsten alloy, steel, etc. At the same time, the directional damage of the entire device to the target is combined with the technologies of UAV mounting and air launch. Utilizing the system cooperation of the detonating network, a diffusive saturation strike within a certain range is achieved, thereby eliminating the problems of high enemy aiming accuracy requirements and limited strike distance when traditional ammunition strikes UAVs. In this way, the strike effect of the UAV is ensured to the greatest extent. In addition, the launch panel can be designed into a flat or curved surface in a circular or square shape according to needs. The launch base uses a corresponding flat charge, and the entire strike system presents a flat block shape. While ensuring that the projectiles have sufficient damage power, the amount of explosive charge is minimized, and multiple strike systems can be mounted side by side on the abdomen of the UAV carrier platform. With the cooperation of simple hanging parts and movable push pins, the combat effect of one UAV with multiple projectiles can be achieved, thus facilitating flexible adjustment according to the load capacity of the carrier platform to meet different usage situations and requirements.

[0018] 2. In the present invention, through the structural design of the detonating network, the detonating function of the detonating network is combined with the damage function of traditional ammunition. Using the UAV as a carrier platform for mounting, dropping, and detonating the strike system, the amount of explosive charge and the strike direction of the damage elements are controlled through the structural design, simplifying the system structure and reducing the amount of explosive charge. In this way, while ensuring the damage effectiveness against the enemy, the collateral damage to the UAV carrier platform is minimized to the greatest extent, avoiding unnecessary collateral damage to the UAV carrier platform, enabling the UAV carrier platform to safely return after dropping all strike systems, and at the same time, continuous bomb dropping can be achieved. For example, one UAV with multiple projectiles can be achieved according to different mounting amounts and return multiple times. While providing the strike ability, the cost of the enemy strike is greatly reduced, thereby ensuring the practicality of the device structure to the greatest extent.

[0023] The following further describes in detail the implementation manner of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] As Figures 1 to 3 shown, a multi-projectile returnable low-altitude strike device and method based on a detonating network includes a hanging part 1 of the UAV platform and a launch panel 4. A connecting part 2 is vertically installed at the top of the hanging part 1 of the UAV platform, and the bottom of the hanging part 1 of the UAV platform is connected to a launch base 3. Moreover, the launch panel 4 is installed on the launch base 3, and a projectile 5 and an explosive 7 are respectively filled on the surface of the launch panel 4. A connecting seat 8 is arranged on one side of the bottom of the launch base 3, and a fixed seat 9 is arranged on one side of the launch base 3. A charge groove structure that can be vertically and horizontally connected for filling the explosive 7 is opened on one side surface of the launch panel 4, and a projectile launch hole structure for filling the projectile 5 is simultaneously opened on one side surface of the launch base 3. The entire launch panel 4 is closely fitted and embedded in the center of the inside of the launch base 3, and the launch base 3 and the hanging part 1 of the UAV platform are movably connected. By filling a number of projectiles 5 on the side vertical surface of the launch panel 4, the projectiles 5 are set in structural shapes such as spheres, cylinders, frustums of cones, and cones, and the projectiles 5 are made of titanium alloy, tungsten alloy, steel, etc. At the same time, the directional damage to the target of the entire device is combined with the UAV hanging and air launch technologies, and the system cooperation of the detonating network is utilized to achieve a diffusive saturation strike within a certain range.

[0025] As Figures 1 to 3As shown in the figure, the top of the connecting member 2 is provided with an interface structure for connecting with the abdomen of the drone, and the upper end of the connecting member 2 is provided with a jack structure for connecting with the abdomen of the drone by using a movable push pin structure. An output hole structure is provided at the staggered position of the charge groove structure on the surface of the fixed seat 9 for filling the initiator 6, and the projectile 5 on the surface of the launch base 3 corresponds to an output hole structure on the surface of one launch base 3. Moreover, the charge groove structure on one side surface of the launch base 3 is arranged in structures such as square, circular, trapezoidal, etc. The initiator 6 and the explosive 7 are made of explosives 7 such as JO type, JH type, HNS, etc. or booster explosives. The explosive 7 is filled into the groove on the surface of the launch panel 4 in the form of powder explosive 7 or slurry through precision pressing, extrusion, and casting processes. The projectile 5 is fixed inside the projectile launch hole structure on the surface of the launch panel 4 by an adhesive. The shape of the projectile 5 includes spheres, cylinders, frustums of cones, and cones, and the material is made of titanium alloy, tungsten alloy, steel, etc. The launch base 3 and the launch panel 4 are fixedly connected by bolts. The launch base 3 and the connection seat 8 are fixedly connected. The drone-mounted platform hanging part 1 and the fixed seat 9 are integrally structured. Moreover, the fixed seats 9 and the connection seat 8 are connected to each other by a movable push pin structure. Through the structural design of the detonation transfer network, the detonation transfer function of the detonation transfer network is combined with the damage function of traditional ammunition. The drone is used as a platform to mount, release, and detonate the strike system. Through the structural design, the filling amount of the explosive 7 and the strike direction of the damage element are controlled, the system structure is simplified, and the filling amount of the explosive 7 is reduced.

[0026] In summary, as Figures 1 to 3 shown, for the one-machine multi-projectile returnable low-altitude strike device and method based on the detonation transfer network, during use, first, the side surface of the launch base 3 is engraved with structures such as charge grooves, input holes, and output holes that can be connected vertically and horizontally. The powder explosive 7 or slurry is filled into the grooves through precision pressing, extrusion, casting, etc. processes. At the same time, the initiator 6 for initiating the launch device is installed in the input hole structure. Inside the projectile launch hole on the surface of the launch panel 4, the projectile 5 is loaded into the hole and fixed with an adhesive. Then, the launch panel 4 is fixedly connected to the launch base 3 by screws. Each projectile corresponds to an output hole of one launch base 3.

[0027] One end of the drone-mounted platform hanging part 1 is connected to the fixed seat 9 at one end of the launch base 3 through the connection seat 8. Among them, it is threadedly connected to the launch base 3 by screws and connected to the drone-mounted platform hanging part 1 by a movable push pin structure. During the hanging flight, the head of the connecting member 2 at the top of the drone-mounted platform hanging part 1 is inserted into the abdomen of the platform and locked by a movable push pin structure. When the strike system needs to be released and strike the target, the movable push pin is pushed out by the built-in push mechanism of the platform, and the drone-mounted platform hanging part 1 disengages from the platform under the action of the self-weight of the strike system and ignites.

[0028] During this process, when the UAV carrier platform locks on the strike target, it sends a strike signal. The carrier platform movement mechanism pushes the movable plunger to release the strike system, and energizes and ignites the pyrotechnic device 6 at the moment when the cable interface is disconnected. The instantaneous or delay pyrotechnic device 6 can be selected according to the required falling height of the strike system. The strike system is detonated by the pyrotechnic device 6 and transmits the detonation energy through the internal charge grooves of the launch panel 4. While the detonation wave propagates inside the grooves, it drives the projectile 5 to shoot out from the launch hole. The projectile flies towards the target area at a certain speed and distribution, achieving the directional strike against the enemy aircraft.

[0029] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
