[0002] In recent years, high-value aviation platforms such as helicopters, early warning aircraft and transport aircraft have been frequently shot down. With the development of missile and unmanned aerial vehicle technologies, the threats faced by aviation platforms are becoming more and more complex, posing a serious challenge to the safety of aircraft platforms and putting forward higher requirements for the self-defense capabilities of aviation platforms. Traditional defense strategies mainly rely on aircraft platforms to perform large-scale flight maneuvers and use electronic jamming and other means. However, with the rapid evolution of cutting-edge missile technology, especially when the aircraft falls within the non-escape zone of such missiles, the defense effect is significantly reduced when using drastic flight evasion maneuvers and electronic countermeasures.

[0003] The current research focus mainly includes laser and defensive missiles, which can directly destroy threat targets to protect the safety of aircraft platforms. For lasers, due to the limited space on aircraft platforms, the on-board power supply cannot provide high power support, and laser interception has been in the development and testing stage on the ground for a long time. Defensive missiles can directly destroy incoming threat targets, but the cost of interception is high, and the technical development is difficult. SUMMARY

[0022] The utility model is further illustrated in connection with the drawings.

[0023] Example one: refer to Figure 1The embodiment provides a net bomb for intercepting a long-distance aerial target, which comprises a wind cap and a net bomb shell body, the wind cap is a thin-wall protective cover which can reduce air resistance during flight, and the bottom of the wind cap is connected with the net bomb shell body; a metal isolation wall is arranged in the net bomb shell body, a gas guide channel is arranged between the metal isolation wall and the net bomb shell body, compressed intercepting nets are arranged in the metal isolation wall, a compressed film cover is arranged on the upper part of the compressed intercepting nets, a powder chamber is connected with the gas guide channel through a gas guide plug, and a mass block is fixedly adhered to the metal isolation wall through strong glue, magnetic force adsorption or the like, the tail of the mass block is connected with the compressed intercepting nets, and a fuse is arranged at the bottom of the net bomb shell body.

[0024] In the embodiment, the powder chamber is arranged between the bottom outer side of the metal isolation wall away from the wind cap and the bottom inner side of the net bomb shell body, the compressed intercepting nets and the powder chamber can also be arranged in the upper and lower parts of the metal isolation wall respectively, and a metal isolation layer is arranged between the two parts.

[0025] By adopting the technical scheme, the compressed intercepting nets are not directly acted on by high-pressure gas generated by the powder chamber, so that the compressed intercepting nets are not damaged.

[0026] In the embodiment, the compressed film cover is arranged above the compressed intercepting nets before the fuse is triggered, so that the intercepting nets are compressed in the metal isolation wall before the fuse is triggered, and the intercepting nets are prevented from being scattered during storage, transportation and flight of the net bomb.

[0027] The compressed film cover is provided with a through hole for a traction rope of the intercepting nets to pass through, the intercepting nets are connected with the mass blocks through the traction ropes arranged uniformly on the periphery of the intercepting nets and the tail of the mass blocks, so that the compressed intercepting nets can be pulled out of the net bomb shell body after the mass blocks obtain kinetic energy.

[0028] In the embodiment, the mass blocks are adhered to the metal isolation wall through strong glue, the number of the mass blocks can be determined according to the characteristics of the intercepted target, and the protruding part of the mass blocks is opposite to the gas guide channel and contacts the net bomb shell body.

[0029] By adhering the mass blocks to the metal isolation wall, the mass blocks can be fixed on the metal isolation wall during the flight of the net bomb, so that the stability of the flight of the net bomb is ensured.

[0030] In the embodiment, the fuse is arranged at the bottom of the net bomb shell body, and the fuse provides a control instruction for the expansion of the intercepting nets.

[0031] Using the above technical solution, aerial target interception information can be loaded before the net projectile is launched. Before the fuse is triggered, all parts of the net projectile fly together in the air.

[0032] In this embodiment, the fuse triggers the gunpowder chamber to generate high-pressure gas based on the information provided, which is then conducted to the gas guide channel through the gas guide plug. By setting the gas guide plug, the high-pressure gas can be controlled to provide sufficient power to the mass block after reaching a certain intensity. When the high-pressure gas acts on the mass block through the gas guide channel, the mass block gains kinetic energy and pulls and compresses the interception net, breaking through the compression film cover, and further breaking through the wind cap to rush into the outer space. After rushing out, the interception net is subjected to the combined action of the traction force and centrifugal force of the mass block at high altitude, enabling it to rapidly rotate and unfold in a designated airspace, contact and entangle with a distant aerial target, and fly together for a period of time, rendering the target ineffective.

[0033] This invention features a simple structural design. The interception net can be precisely controlled to deploy under the action of the fuse and mass blocks, and can be quickly pulled into shape in the air, improving the safety and stability of aerial target interception. At the same time, the number of mass blocks designed in this invention can be flexibly adjusted according to the characteristics of the intercepted target and the size of the interception net, making it widely applicable and inexpensive.

[0034] Example 2: The overall structure of the net-shaped missile for long-range aerial target interception provided by this utility model is the same as that of Example 1. See attached diagram for details. Figures 1-4 A specific example is provided to further describe the specific structure of this solution:

[0035] As attached Figures 1 to 3 As shown, the net-bomb structure proposed in this embodiment specifically includes a wind cap 1 and a net-bomb shell 2. The wind cap 1 is a thin-walled protective cover that can reduce flight drag. The bottom of the wind cap 1 is connected to the net-bomb shell 2. A metal partition wall 4 is provided inside the net-bomb shell 2. An air guide channel 3 is located between the metal partition wall 4 and the net-bomb shell 2. A compressed interception net 8 is provided inside the metal partition wall 4. A compression film cover 10 is provided at the top of the compressed interception net. The propellant chamber 7 is connected to the air guide channel 3 through an air guide plug 5. A mass block 9 is adhered to the metal partition wall 4 with strong adhesive. The tail of the mass block 9 is connected to the compressed interception net 8. A fuse 6 is provided at the bottom of the net-bomb shell 2. Under the action of the fuse 6, the timing of the interception net's deployment in the air can be precisely controlled, enabling the interception of long-range aerial targets with high control accuracy and good reliability.

[0036] The mass block 9 is adhered to the metal isolation wall 4 with strong adhesive. The protruding part of the mass block 9 faces the air guide channel 3 and contacts the net shell 2. This ensures that the mass block 9 can be fixed to the metal isolation wall 4 during the flight phase of the intercept net projectile, thus ensuring the stability of the intercept net projectile's flight.

[0037] The protective wind cap 1 for reducing air resistance is set on the upper part of the net shell 2, and the compression film cover 10 is set on the upper part of the compression interception net 8. The design is reasonable and can ensure that the inside of the interception net will not fall apart during storage, transportation and flight, and that the interception net will not become entangled during the flight of the net, thus improving the stability and safety of the interception net.

[0038] The compressed interception net 8 and the gunpowder chamber 7 are respectively deployed in the upper and lower parts of the metal isolation wall 4. The metal isolation wall 4 is provided between the compressed interception net 8 and the gunpowder chamber 7. When the gunpowder chamber 7 generates high-pressure gas, it does not directly act on the compressed interception net 8, ensuring that the interception net is not damaged.

[0039] The compression film cover 10 has holes, through which the traction rope of the compression interception net 8 can pass and be connected to the tail of the mass block 9. After the mass block 9 gains kinetic energy, it can pull the compression interception net 8 out of the net shell 2.

[0040] The fuse 6 triggers the gunpowder chamber 7 to generate high-pressure gas according to the information in the package. The gas is then conducted to the gas channel 3 through the gas guide plug 5. By setting the gas guide plug 5, the high-pressure gas can be controlled to pass through the gas guide plug 5 after reaching a certain intensity, thus providing sufficient power to the mass block 9.

[0041] When high-pressure gas acts on the mass block 9 through the gas guiding channel 3, the mass block 9 gains kinetic energy and pulls the compression interception net 8 to break through the compression film cover 10. The mass block 9 then breaks through the wind cap 1, and the mass block 9 can pull the compression interception net 8 to break through the net shell 2 together.

[0042] The interception net 8 is subjected to the combined action of centrifugal force and the traction force of the mass block 9 at high altitude, and rapidly rotates and unfolds in the designated airspace. It can make contact with and entangle with distant aerial targets and fly together for a period of time, rendering the targets ineffective.

[0043] As attached Figure 4 As shown, the interceptor net 8 can adopt a square structure design, with four mass blocks 9 evenly arranged on the corners of the unfolded edge, resulting in uniform mass distribution and good stability. Different shapes of interceptor nets can be designed according to interception requirements, and the number and mass of the mass blocks 9 can be adjusted according to the characteristics of long-range aerial targets, allowing for greater damage to the intercepted targets and broad application range. The net material can be made of high-strength, lightweight, and high-temperature resistant fiber material, meeting the requirements of aerial platforms.

[0044] The utility model mainly aims at long distance air threat target, combines and designs a net bomb of intercept net, provides new train of thought for air target interception. Through with the mass 9 adhering in the metal insulation wall 4, setting up the compression film cover 10 and the resistance wind cap 1, design is reasonable, can ensure that the intercept net bomb inside will not scatter in storage, transportation, flight process, the intercept net 8 will not occur winding in the net bomb flight process, has improved the stability and security of intercept net bomb. The intercept net bomb can combine the launch system and the power body, under the action of the fuse 6, accurately control the expansion time of the intercept net in the air, can implement the interception to long distance air target, control precision is high, the mass 9 is evenly distributed in the edge of the intercept net, makes the intercept net mass distribution even, stability is good, the number and mass of the mass 9 in the intercept net bomb can be adjusted flexibly according to the characteristics of long distance air target, and the scope of application is wide.

The above description is only the preferred embodiment of the utility model, and does not limit the structure of the utility model. Obviously, those skilled in the art can make various modifications and changes in form and detail without departing from the principle and structure of the utility model. However, these modifications and changes based on the utility model idea are still within the protection scope of the claims of the present application.
