Description

Technical Field

[0001] The present application belongs to the technical field of aerial missile interception, and in particular relates to an aerial passive missile interception net bomb and an interception method. Background Art

[0002] In the process of modern aircraft air games, with the continuous development of various advanced missile technologies, the air survivability of high-value air targets such as various types of aircraft has become increasingly weak. In particular, some aircraft are more likely to be targeted and destroyed by the opponent because of their large role and strong radiation signals. The traditional response method is to rely on one's own aircraft escort and use infrared / chaff bombs as the last means of self-protection. However, with the continuous improvement of the anti-interference capability of air-to-air missiles and the continuous enhancement of the ability to attack highly maneuverable targets, as well as the large-scale application of unguided close-range direct-aiming weapons such as rocket-propelled grenades, the limitations of traditional aircraft protection methods such as soft kill and maneuver evasion are increasingly exposed.

[0003] In view of the above reasons, a technology is needed to overcome or alleviate the above defects. Summary of the invention

[0004] The purpose of this application is to provide an airborne passive missile arresting net bomb and an arresting method to solve or alleviate at least one problem in the background technology.

[0005] The technical solution of the present application is: an airborne passive missile arresting net bomb, comprising: a warhead, a body and a tail, wherein the warhead, the body and the tail are connected in sequence;

[0006] The tail of the projectile is provided with a propulsion system, a delayed ignition controller, a powder chamber and a separation chamber. The propulsion system is used to provide power for the arresting net projectile. The delayed ignition controller is used to control the ignition of the powder chamber. The powder chamber is filled with separation fuel for separating the projectile body from the tail of the projectile. The separation chamber is used to control the separation of the projectile body and the tail of the projectile.

[0007] A flexible arresting net having a predetermined shape after being unfolded is arranged in the projectile body, and a traction ball is connected to the top corner or edge of the flexible arresting net, and the traction ball is located in a separation chamber at the connection position between the projectile tail and the projectile body.

[0008] Preferably, the warhead is configured to have a low wind resistance shape.

[0009] Preferably, the shape of the flexible barrier net after unfolding includes triangle, rectangle, rhombus, hexagon or circle.

[0010] Preferably, the material of the flexible barrier net includes plastic fiber material, metal fiber material and mixed material.

[0011] Preferably, the traction ball is a lead ball or a steel ball.

[0012] Preferably, the projectile body also includes a deceleration parachute, which is arranged at at least one traction ball position and is used to decelerate part of the traction balls when the flexible arresting net and the traction balls are separated from the projectile body, thereby causing a speed difference in the traction balls, facilitating the deployment of the flexible arresting net and extending the on-track arresting time of the flexible arresting net, while increasing the resistance of the incoming target wrapped by the flexible arresting net, and the generated resistance is uneven, causing the incoming target to lose direction.

[0013] Preferably, the deceleration parachute is a multi-layer structure, which includes a heat protection layer and a bearing layer, and the heat protection layer is located outside the bearing layer.

[0014] Preferably, the heat protection layer material includes ceramic fiber material and polyimide material.

[0015] Preferably, the surface of the flexible barrier net is covered with high-combustibility gunpowder, and the high-combustibility gunpowder can be detonated by impact with an incoming target.

[0016] In addition, the present application also provides a method for intercepting using any of the above-mentioned airborne passive missile interception net bombs, comprising:

[0017] S1. When the carrier aircraft detects an incoming target, it launches an interception net missile;

[0018] S2. After the arresting net missile flies a certain distance by relying on the propulsion system, it starts to perform the separation task. The separation fuel in the gunpowder chamber is ignited by the delayed ignition controller to generate high-temperature and high-pressure gas, and the explosion impact force is used to separate the tail of the missile from the missile body and the warhead.

[0019] S3. When the tail of the projectile is separated from the projectile body and the warhead, the high-temperature and high-pressure gas ejects the traction balls connected to the flexible arresting net in the separation chamber from the separation chamber, giving the traction balls initial kinetic energy to pull the flexible arresting net to open, thus achieving safe separation of the projectile and the net;

[0020] S4. The flexible arresting net is stretched open by multiple traction balls to form an arresting area in the air;

[0021] S5. After the incoming target collides with the flexible arresting net at high speed, the flexible arresting net will wrap around the incoming target's body and remain attached to the incoming target's body for a long time, flying with it. Under the action of aerodynamics and the entanglement of the flexible arresting net, it will deviate from the normal trajectory.

[0022] The aerial passive arresting net bomb provided by the present application is low-cost and cost-effective. It can intercept portable missiles that are dozens of times more valuable than it. It is flexible to use and highly versatile. It can be installed on various aircraft in the form of an external pod. It has little effect on the main structure and layout of the carrier aircraft. It is flexible to use and can be temporarily decided whether to carry it according to the tasks and changes undertaken by the carrier aircraft. It can also be quickly installed and disassembled.

[0025] Figure 2 This is a schematic diagram of the interior of the airborne passive missile arresting net bomb of this application.

[0026] Figure 3 This is a schematic diagram of the airborne passive missile arresting net intercepting the missile after separation. DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0028] like Figure 1 and Figure 2 As shown, the airborne passive missile arresting net bomb provided by the present application includes: a warhead 1, a body 2 and a tail 3, and the warhead 1, the body 2 and the tail 3 are connected in sequence to form a whole.

[0029] The tail 3 is provided with a propulsion system 31, a delayed ignition controller 32, a powder chamber 33 and a separation chamber 34. The propulsion system 31 is used to provide power for the arresting net bomb, the delayed ignition controller 32 is used to control the ignition of the powder chamber 33, the powder chamber 33 is filled with separation fuel for separating the body 2 and the tail 3, and the separation chamber 34 is used to control the separation of the body 2 and the tail 3.

[0030] It should be noted that the powder chamber 33 can be filled with fuel such as high-combustion powder, but on the basis of achieving separation of the projectile body 2 and the projectile tail 3, the powder chamber 33 can be filled with flammable gas such as hydrogen or high-pressure gas.

[0031] The missile body 2 includes a flexible arresting net 21, a traction ball 22 and a deceleration parachute 23. The flexible arresting net 21 is in a predetermined shape after being deployed, and is loaded and arranged inside the missile body 2. The traction ball 22 is connected to the top corner or edge of the flexible arresting net 21, and the traction ball 22 is located in the separation chamber 34 at the connection position between the tail 3 and the missile body 2.

[0032] In some embodiments of the present application, the shape of the flexible barrier net 21 after unfolding can be a triangle, rectangle, rhombus, hexagon or circle, etc. When the flexible barrier net 21 is a polygonal structure such as a rectangle or rhombus, the traction ball 22 is set at the top corner of the polygonal structure. When the flexible barrier net 21 is a circle, the traction ball 22 can be set on the edge of the diameter.

[0033] Furthermore, the material of the flexible barrier net 21 can be plastic fiber material, metal fiber material, or a mixed material.

[0034] In the present application, the traction ball 22 is used to open the flexible arresting net 21 as much as possible under the action of inertia. In some embodiments of the present application, the density of the traction ball 22 is usually large, and it can be a lead ball or a steel ball, so that the flexible arresting net 21 can be opened as much as possible.

[0035] The deceleration parachute 23 is arranged at the position of at least one traction ball 22, and is used to decelerate part of the traction ball 22 when the flexible arresting net 21 and the traction ball 22 are separated from the missile body 2, so as to generate a speed difference in the traction ball 22, which is convenient for the deployment of the flexible arresting net 21. The deceleration parachute 23 can, on the one hand, slow down the descent speed of the flexible arresting net 21 when it falls, and prolong the arresting time of the flexible arresting net 21 on the track. On the other hand, it increases the resistance of the incoming target wrapped by the flexible arresting net 21, and the generated resistance is uneven, causing the incoming target to lose direction.

[0036] In some embodiments of the present application, the deceleration parachute 23 is a multi-layer structure, which includes a heat-proof layer and a bearing layer. The heat-proof layer is located outside the bearing layer to prevent the heat in the gunpowder chamber 33 from damaging the deceleration parachute 23.

[0037] Furthermore, the heat protection layer material may be ceramic fiber or polyimide or other materials.

[0038] In the preferred embodiment of the present application, the surface of the flexible arresting net 21 is covered with high-combustibility gunpowder, which is passively detonated by the impact of the incoming target, thereby destroying the fairing and the body of the incoming target. The exposed guidance system will fail under the influence of the high-temperature and high-speed airflow, thereby losing its guidance capability, thereby achieving reliable protection of our high-value flying targets.

[0039] In some embodiments of the present application, a blocking cover 24 is provided at the outlet of the projectile body 2 for accommodating the flexible arresting net 21 to prevent the flexible arresting net 21 from being damaged during the separation process.

[0040] The warhead 1 is arranged at the front end of the warhead body 2, which is designed to have a low wind resistance shape.

[0041] Combination Figure 3 As shown, the process of the air passive interception net missile of the present application for air passive missile interception includes:

[0042] S1. When the carrier aircraft detects an incoming target, it launches an interception net missile;

[0043] S2, the arresting net missile starts to perform the separation task after flying a certain distance by the propulsion system 31, and ignites the separation fuel in the gunpowder chamber 33 through the control of the delayed ignition controller 32, and the high-temperature and high-pressure gas generated uses the explosion impact force to separate the tail 3 from the missile body and the warhead 1;

[0044] S3, while the tail 3 is separated from the body 2 and the warhead 1, the high-temperature and high-pressure gas ejects the traction balls 22 at the top corners of the flexible arresting net 21 in the separation chamber 34 from the separation chamber 34, giving the traction balls 22 initial kinetic energy, pulling the flexible arresting net 21 to open, and realizing the safe separation of the net;

[0045] S4. The flexible arresting net 21 is stretched out by the multiple traction balls 22 to form a large arresting area in the air. Some of the traction balls 22 carry the deceleration parachutes 23. After the flexible arresting net 21 is fully deployed, the deceleration parachutes 23 are opened to reduce the descent speed of the flexible arresting net 21 in the air and increase the probability of intercepting the incoming target.

[0046] S5. After the incoming target (not shown) collides with the flexible arresting net 21 at high speed, the high-performance flexible arresting net 21 will wrap the incoming target's projectile and remain attached to the incoming target's projectile for a long time and fly with it; the incoming target will deviate from the normal trajectory due to the aerodynamic effect and the entanglement of the flexible arresting net 21; the high-burning explosives arranged on the surface of the flexible arresting net 21 will be passively detonated under the high-energy impact of the incoming target, and the aerodynamic shape and internal structure of the incoming target will be destroyed, thereby completely losing its offensive capability, thereby achieving reliable protection of our high-value flying targets.

[0047] The airborne passive interception net bomb provided by the present application is low-cost and cost-effective. It can launch multiple interception net bombs and at the same time intercept portable missiles with a value dozens of times higher than that of the interception net bomb. It is flexible to use and has strong versatility. It can be installed on various aircraft in the form of an external pod. It has little effect on the main structure and layout of the carrier aircraft. It is flexible to use. It can be temporarily decided whether to carry it according to the tasks and changes undertaken by the carrier aircraft. It can be quickly installed and disassembled. It is not only easy to use and maintain, but also with the advancement of technology, the interception net bomb can be improved and upgraded in time. It can provide aircraft with close-range hard kill protection means that are different from traditional soft interference, which will greatly improve the survivability of aircraft in air confrontation, greatly preserve our own vitality, and intercept all types of incoming targets in the air. It has a wide range of applications.

[0048] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
