Embodiment 1

[0040] refer to figure 1 , the anti-drone rope net capture method provided in this embodiment is divided into three stages:

[0041] First, in the form of a missile with a certain initial velocity v 0 and launch angle α 0 , the total mass launched to the UAV target is m 0 And the capture platform with the rope net launching mechanism is encapsulated.

[0042]When the capture platform flies to a certain distance from the UAV target, the rope net transmitter in the capture platform launches the rope net at the set launch speed and launch angle. It itself includes a parachute bag for shell collection. After the capture platform launches the rope net, the parachute umbrella bag for shell case collection is opened and fully inflated, and then falls steadily with the capture platform to realize the collection of the capture platform itself. The rope net expands and collides with the UAV target to entangle, completing the capture of the UAV target.

[0043] After the capture is...

Embodiment 2

[0046] For the anti-drone rope net capture method provided in the above-mentioned embodiment 1, the present embodiment provides the basis for judging that the rope net successfully captures the drone target, as follows:

[0047] like figure 2 As shown in , it is assumed that the speed variation range of the UAV target flying along the horizontal direction is in The maximum maneuvering radius of the UAV target in the vertical direction is R. The criterion for defining the successful capture of the UAV target by the rope net is: at the moment when the rope net collides with the UAV, the projection surface S of the polygon formed by the net mouth of the rope net in the vertical plane NP A set S of high-probability location points that can cover UAVs UAV .

[0048] like image 3 As shown, at the instant the rope net is launched, the horizontal distance between the capture platform and the center point of the maneuvering plane of the UAV is d UAV , the height difference ...

Embodiment 3

[0058] Based on the anti-drone rope net capture method provided in embodiment 1 and the judgment basis that the rope net provided in embodiment 2 successfully captures the drone target, this embodiment provides the capture platform launch rope net in the anti-drone rope net capture method The optimal design method of the launch speed and launch angle of the capture platform is presented, where the launch angle includes the capture platform's attack angle α and pitch angle θ when the capture platform launches the rope net.

[0059] Factors affecting the deployment of the rope net include the size and configuration of the rope net, the material used for the rope net, the quality of the rope net, the folding method of the rope net, the size and material of the net bag, the launch speed and launch angle of the mass block, and the weight of the mass block. quality and more.

[0060] The independent variables to be optimized selected in the present invention include rope net paramet...

Abstract

The invention relates to an anti-unmanned aerial vehicle rope net capturing method. The method comprises the steps that firstly, a capturing platform packaged with a rope net launching mechanism is launched to an unmanned aerial vehicle target; when the capturing platform flies to a certain distance away from the unmanned aerial vehicle target, the capturing platform transmits a rope net at a settransmitting speed and a set transmitting angle, wherein the back surface of the rope net is connected with a parachute pack, and the rope net is unfolded to collide and wind with the unmanned aerialvehicle target to complete capturing of the unmanned aerial vehicle target; and after capturing is completed, the parachute pack is opened and inflated and then stably falls down together with the rope net capturing the unmanned aerial vehicle target. According to the anti-unmanned aerial vehicle rope net capturing method, the rope net capturing anti-unmanned aerial vehicle means is employed, andthe whole process of launching flight of the capturing platform, unfolding capturing of the flexible rope net and recovery of a parachute is combined. Furthermore, a judgment basis for successfully capturing the unmanned aerial vehicle target by the rope net is provided, and rope net launching parameters in the anti-unmanned aerial vehicle rope net capturing method are optimized, so that the success rate of capturing the unmanned aerial vehicle by the rope net is improved.

Description

technical field [0001] The invention belongs to the technical field of anti-drone, and in particular relates to an anti-drone rope net capture method. Background technique [0002] The development of civilian drone technology has made drones cheaper, easier to operate, and easier to obtain. They are playing an increasingly important role in terrain mapping, mineral detection, and earthquake disaster warning and survey. But at the same time, civilian drones have become the main medium for various sabotage activities due to their small size, low flying airspace, and difficulty in radar detection. At present, there have been many incidents of UAVs illegally entering sensitive airspace and UAV drug trafficking, smuggling and violent activities in the world, which have brought major challenges and hidden dangers to social stability and security. Therefore, anti-UAV technology has become a near Over the past few years, it has been a hot topic that countries around the world have ...
