[0040] The bottom of the cartridge case 1 is provided with a mounting hole for assembling a propellant charge 2, and the bottom of the mounting hole is provided with a plurality of pressure relief holes 1.1 connected to the inner cavity of the cartridge case 1, and the propellant charge 2 is threadedly connected to the mounting hole; the outer wall at the bottom of the cartridge case 1 is provided with an annular groove 1.2 for adapting to and fixing the launcher.

[0041] The propellant charge 2 comprises a bottom screw 2.1, propellant 2.2, a powder fixing ring 2.3, a copper sheet 2.4 and a primer 2.5. The bottom screw 2.1 is threadedly connected to the cartridge 1. The propellant 2.2 is loaded in the bottom screw 2.1 and fixed by the powder fixing ring 2.3. The copper sheet 2.4 is arranged on the powder fixing ring 2.3 to block the pressure relief hole 1.1 and prevent the propellant 2.2 from getting wet.

[0042] The traction head seat 4 is a hollow cone-shaped body with a larger top and a smaller bottom, and is preferably made of aluminum alloy. A plurality of outwardly inclined sockets 4.1 for mounting the traction head 5 are arranged in a circular array on the traction head seat 4, and a blind hole 4.2 is provided at the bottom of the traction head seat 4, which is connected to the socket 4.1 and fixedly assembled with the cartridge 1.

[0043] The net tube 3 is in the shape of a cylinder with a sealed bottom and an open top, and its inner surface is designed with smooth rounded corners to ensure the convenience and reliability of the capture net during assembly and unloading. A limiting flange 3.1 is provided on the top of the net tube 3, and the limiting flange 3.1 of the net tube 3 is arranged in a blind hole 4.2 and is pressed against the cartridge 1 by the traction head seat 4, and an airway is provided between the outer wall of the net tube 3 and the cartridge 1, and a plurality of vents 3.2 corresponding to the plug hole 4.1 are provided on the limiting flange 3.1, so that the airway is connected to the plug hole 4.1.

[0044] The capture net 6 is a polygonal capture net, preferably a hexagonal capture net, and each corner is provided with a traction head 5, which is preferably made of stainless steel and inserted into the socket 4.1 of the traction head seat 4, and the capture net 6 is loaded into the net cylinder 3. Preferably, the traction head 5 of this embodiment is provided with a plurality of sealing rings 5.1, which are used for sealing in the socket 4.1, so that a certain starting pressure is established in the traction head socket to ensure the initial speed of the traction head.

[0045] The preferred assembly method of the net cylinder of this embodiment is: the lower surface of the limiting flange 3.1 of the net cylinder 3 abuts against the cartridge 1 and is pressed by the traction head seat 4, and the cartridge 1 is threadedly connected with the blind hole 4.2 of the traction head seat 4.

[0046] When assembling the net-catching bomb: turn the traction head seat upside down, put the limit flange of the net cylinder into the blind hole of the traction head seat, align the plug hole and the vent hole (the vent hole is preferably a side opening hole), then install the bomb cylinder assembled with the propellant charge into the traction head seat and tighten it, and finally load the net-catching bomb. The loading steps are as follows:

[0047] S1. Spread out the capture net;

[0048] S2, installing the traction heads of the capture net one by one into the sockets in the spare traction head seat;

[0049] S3. Grasp the center of the capture net, straighten it and smooth it out, then gradually push the capture net into the middle of the traction head seat of the capture net bomb to be filled. When it is filled to the mouth of the capture net bomb, remove the traction head seat from the spare traction head seat and install it into the traction head seat of the capture net bomb.

[0050] Working principle: After the launcher fires the primer, the primer ignites the propellant. When the pressure in the high-pressure chamber of the propellant reaches the puncture pressure, the gunpowder gas breaks through the copper sheet and enters the space composed of the cartridge and the net tube (i.e., the airway) through the pressure relief hole. As the pressure in this space rises, when the starting pressure of the traction head is reached, the traction head drives the capture net to fly out with a certain kinetic energy. During the flight, the traction head gradually disperses to the surroundings at a certain angle, causing the capture net to gradually open, thereby achieving the capture of targets at a certain distance on the flight trajectory.

[0051] Embodiment 2

[0052] On the basis of the first embodiment, this embodiment further optimizes the assembly method of the net cylinder, as shown in the attached Figure 3 and attached Figure 4 As shown, in this embodiment, a plurality of positioning holes 4.3 are provided at the bottom of the blind hole 4.2 of the traction head seat 4, and a positioning column 3.3 plugged into the positioning hole 4.3 is provided on the end face of the limit flange 3.1 of the net cylinder 3. The positioning column of the net cylinder and the positioning hole of the traction head seat are used for positioning and assembling, so as to ensure the relative position of the net cylinder and the traction head seat, and prevent the net cylinder from rotating during the assembly process and causing the vent hole and the plug hole to be misaligned.

[0053] Embodiment 3

[0054] The difference between this embodiment and the first or second embodiment is that the assembly method of the net cylinder is different. Figure 1 In this embodiment, the limiting flange 3.1 of the net cylinder 3 is threadedly connected to the cartridge 1, and the cartridge 1 is interference-fitted with the blind hole 4.2 of the traction head seat 4 or / and fixed by multiple screws. In the assembly type, the bottom of the net cylinder is inserted into the cartridge, and the limiting flange is threadedly connected to the cartridge. At this time, the net cylinder is fixed in the cartridge, and then the jack of the traction head seat is aligned with the vent hole of the limiting flange, and finally the traction head seat is pressed into the cartridge.

[0055] Embodiment 4

[0056] On the basis of any of the above embodiments, this embodiment further designs the traction head seat and the traction head, as shown in the attached Figure 1 and attached Figure 2 As shown, the longitudinal section of the insertion hole 4.1 of the traction head seat 4 is set to be "T" shaped, and the longitudinal section of the traction head 5 is also set to be "T" shaped to match it. This design allows the traction head to be well positioned in the traction head seat, and the insertion depth of each traction head is consistent, ensuring the consistency of the initial velocity after launch.

[0057] Embodiment 5

Specifically, during installation, the corner of the sealing sheet is inserted into the slot of the traction head at the position where the slot of the traction head exposes the traction head seat (the corner is aligned with the guide groove of the traction head seat), and then the traction head and the sealing sheet are pushed into place together. The sealing sheet designed in this embodiment can prevent the capture net from spilling during transportation, and can also cover the capture net to improve the aesthetics of the ammunition.

[0060] In specific applications, the net-catching bomb is configured as a mechanical primer, which is suitable for existing grenade launchers or heavy-loaded drones. It can also be configured as an electronic primer and loaded on small and medium-sized drones through a fixture.
