Description

Technical Field

[0001] This invention belongs to the field of electronic countermeasures technology, specifically a parachute-shaped chaff that can simultaneously counter radar-guided and infrared-guided missiles. Background Technology

[0002] With the rapid development of infrared detection, infrared guidance, and military computer technologies, new infrared-guided missiles employ more advanced terminal guidance technologies, such as infrared dual-color guidance, infrared imaging guidance, and multi-mode composite guidance, making the missiles more intelligent and possessing all-around attack capabilities. Traditional infrared countermeasures are no longer effective in interfering with these advanced missiles, posing new challenges to flight platforms.

[0003] Traditional chaff may have limitations in terms of jamming effect, effective range, and duration. They cannot simultaneously counter threats guided by infrared and radar, and may not have the ability to reduce descent speed, affecting the sustainability and stability of the jamming effect. Utility Model Content

[0004] The purpose of this invention is to provide an umbrella-shaped chaff that can simultaneously counter radar-guided and infrared-guided missiles, thereby solving the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A parachute-shaped decoy that can simultaneously counter radar-guided and infrared-guided missiles includes a rectangular spring cavity with an elliptical propellant cage at the bottom. Triangular metal plates are provided around the rectangular spring cavity. The triangular metal plates are isosceles triangles with their bases rotatably connected to the upper side of the rectangular spring cavity. A lightweight air resistance membrane is provided between the edges of adjacent triangular metal plates.

[0007] The rectangular spring cavity is equipped with pulleys on all four sides of its top. The apex of the triangular metal piece is connected to one end of a metal rope. The other end of the metal rope passes through the pulleys and extends into the rectangular spring cavity, where it is connected to a spring striker. A spring is connected above the spring striker, and the metal rope passes through the spring.

[0008] Preferably, a piezoelectric fuse is provided below the spring striker, and a magnesium strip ignition transition section and an ignition task section are provided below the piezoelectric fuse. The elliptical agent cage cavity is filled with thermite, and the thermite covers the outside of the ignition task section.

[0009] Preferably, a metal rope fixing piece is provided at the apex of the triangular metal piece, and one end of the metal rope is connected to the metal rope fixing piece and fixed by a metal rope fixing cap.

[0010] Preferably, the air resistance membrane is made of conductive fabric or nylon material.

[0011] Preferably, the elliptical medicine cavity is made of tungsten material and has a hollow structure with several openings on its outer wall.

[0012] Preferably, when the four triangular metal plates are in close contact with the rectangular spring cavity, the air resistance membrane is in a folded state and is covered with a metal shell. The metal rope pulls the spring striker away from the piezoelectric fuse, and the spring is in a compressed state. At this time, the decoy is in a safe state.

[0013] Preferably, when the metal outer shell is removed, the compressed spring releases pressure, causing the spring firing pin to strike the piezoelectric fuse, igniting the thermite. Light and heat are released outward through the opening of the elliptical propellant chamber. Simultaneously, the metal rope connected to the spring firing pin moves, pulling the triangular metal plate up through a pulley. The upturned triangular metal plate can scatter radio waves, and the lightweight air resistance membrane also changes from being tightened to being expanded, increasing the overall air resistance of the chaff and thus extending its loiter time, giving the aircraft that releases the chaff more time to escape. At this time, the chaff is in working condition.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] In this invention, a novel heat jamming method is provided by triggering a thermite reaction through a spring-loaded fuse similar to that in a hand grenade, which generates a large amount of heat to interfere with infrared-guided missiles. This method is easier to operate and has an umbrella-like canopy structure. It uses triangular metal sheets to reflect radio waves and a lightweight air resistance membrane to reduce descent speed. Furthermore, it combines infrared and radar jamming technologies to provide a dual-mode countermeasure solution that simultaneously counters two guidance methods, thereby improving the survivability and battlefield adaptability of the flight platform.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0038] Example:

[0039] A type of umbrella-shaped decoy that can simultaneously counter radar-guided and infrared-guided missiles, such as Figure 1-10 As shown, it includes a rectangular spring cavity 5, an elliptical drug cage cavity 6 at the bottom of the rectangular spring cavity 5, and triangular metal pieces 3 around the rectangular spring cavity 5. The triangular metal pieces 3 are isosceles triangles with their bases rotatably connected to the upper side of the rectangular spring cavity 5. A lightweight air resistance membrane 4 is provided between the edges 16 of adjacent triangular metal pieces 3.

[0040] The rectangular spring cavity 5 has pulleys 1 on all four sides of the top. The apex of the triangular metal piece 3 is connected to one end of the metal rope 2. The other end of the metal rope 2 passes through the pulleys 1 and extends into the rectangular spring cavity 5, and is connected to the spring striker 10. A spring 9 is connected above the spring striker 10, and the metal rope 2 passes through the spring 9.

[0041] In one possible implementation, a piezoelectric fuse 11 is provided below the spring striker 10, and a magnesium strip ignition transition section 12 and an ignition task section 13 are provided below the piezoelectric fuse 11. The elliptical agent cage cavity 6 is filled with thermite 14, and the thermite 14 covers the outside of the ignition task section 13.

[0042] In one possible implementation, a metal rope fixing piece 17 is provided on the apex of the triangular metal piece 3, and one end of the metal rope 2 is connected to the metal rope fixing piece 17 and fixed by the metal rope fixing cap 8.

[0043] In one possible implementation, the air resistance membrane 4 is made of conductive fabric or nylon material, as long as it has a certain strength and can slow down the descent speed of the chaff and prevent it from tearing when the chaff and flare lands.

[0044] In one possible implementation, the elliptical medicine cavity 6 is made of tungsten and has a hollow structure with several openings on its outer wall.

[0045] In one possible implementation, the triangular metal sheet 3 is connected to the edge 16 of the lightweight air resistance membrane 4 via the edge 16. The lightweight air resistance membrane 4 is connected to the triangular metal sheet 3 via the edge 16. The metal rope fixing piece 17 is connected to the triangular metal sheet 3. The metal rope fixing cap 8 fixes the metal rope 2 to the metal rope fixing piece 17 on the triangular metal sheet 3.

[0046] In one possible implementation, when the four triangular metal pieces 3 are in close contact with the rectangular spring cavity 5, the air resistance membrane 4 is in a folded state and is covered with a metal outer shell 15. The metal rope 2 pulls the spring striker 10 away from the piezoelectric fuse 11, and the spring 9 is in a compressed state. At this time, the chaff is in a safe state.

[0047] In one possible implementation, when the metal outer casing 15 is removed, the compressed spring 9 releases pressure, causing the spring firing pin 10 to strike the piezoelectric fuse 11, igniting the thermite 14. Light and heat are released outward through the opening of the elliptical propellant chamber 6. Simultaneously, the metal rope 2 connected to the spring firing pin 10 moves, pulling the triangular metal piece 3 up through the pulley 1. The upturned triangular metal piece 3 can scatter radio waves, and the lightweight air resistance membrane 4 also changes from being tightened to being expanded, increasing the overall air resistance of the chaff and thus prolonging the loiter time, giving the aircraft that releases the chaff more time to escape. At this time, the chaff is in working condition.

[0048] In one possible implementation, four triangular metal pieces 3 are distributed on the outside of the rectangular spring cavity 5, kept in close contact. A metal rope 2 connected to the pointed end of each triangular metal piece 3 is connected via a pulley 1 to the front end of a spring firing pin 10 located inside the pulley spring cavity. When the triangular metal pieces 3 are in close contact, the metal rope 2 pulls the spring firing pin 10, preventing it from striking the piezoelectric fuse 11. The spring 9 is in a compressed state, and the chaff is in a safe state, unable to transmit radio waves.

[0049] In one possible implementation, once the triangular metal piece 3 is released from its safety mechanism, the spring pressure is released, causing the spring firing pin to strike the piezoelectric fuse and ignite the thermite. Light and heat are released outward through the opening of the elliptical propellant chamber. Since the temperature of the thermite 7 exceeds 2000 degrees Celsius, the propellant chamber is made of tungsten material. Simultaneously, the thin rope connected to the spring firing pin 10 moves, pulling the triangular metal piece 3 up through a pulley. The uplifted triangular metal piece 3 can scatter radio waves, and the lightweight air resistance membrane also changes from being tightened to being expanded, increasing the overall air resistance of the decoy and thus extending its loiter time, giving the aircraft releasing the missile more time to escape. At this time, the decoy is in working condition. The radio waves emitted by the scatterable guided fire control radar can also interfere with and deceive infrared-guided missiles through light and heat, thus forming dual-mode interference against radar and infrared.

[0050] In one possible implementation, the safety can be secured by wrapping the metal sheet with an elastic material or by placing it in a rectangular shell of similar size. This safety is not an essential technical feature of this application, which merely illustrates an example of encasing the metal shell 15 on the outside.

[0051] In one possible implementation, an essential feature of this application is that the connection between the triangular metal sheet 3 and the spring striker 10, and their energy conversion relationship with the spring, are key factors in triggering the two actions of the metal sheet springing up and the thermite 7 igniting.

[0052] In one possible implementation, due to the high temperature of the thermite 7, the overall shape of the elliptical agent chamber is crucial for heat release and long-term release without melting. The primary objective of the metal sheet is to scatter electromagnetic waves and expand the lightweight air resistance film; therefore, its shape is not a critical factor.

[0053] In one possible implementation, the spring force can cause the spring firing pin to pull the metal rope, thereby indirectly pulling the triangular metal piece 3. Therefore, by constraining the triangular metal piece, the firing pin can be indirectly pulled to keep the spring 8 in a compressed state. Thus, the overall safe state of the decoy projectile refers to the metal piece being attached to the outside of the rectangular spring cavity by some kind of safety measure. This safety measure could be something like a sealed metal casing 15 as shown in the figure, or other means. Once the safety measure is released, the firing pin begins to move. The brief period before impact with the piezoelectric fuse is a transitional state between the safe and operational states. This transitional period is very short, and the decoy projectile can be considered to be in the operational state, which is also the released state. However, this safety measure is not a claim of this application; it is only used to illustrate the working principle of the decoy projectile. In the safe state, the spring firing pin maintains a certain distance from the piezoelectric fuse 11.

[0054] In one possible implementation, when the safety mechanism is disengaged, the metal rope rapidly loses its tension balanced with the spring force, and the spring force is released instantaneously. This triggers the impact of the spring firing pin 10 on the piezoelectric fuse 11. The impact causes the fuse to deform, generating a piezoelectric effect, which ignites a spark, setting off the magnesium strip's ignition transition section 12, and subsequently igniting the mission section 13. The main feature of the mission section magnesium strip 13 is that it increases the contact area with the thermite 14 and maintains the burning time, ensuring the thermite reaction of the thermite 14 is initiated. A large amount of light and heat is released outward through the rectangular opening of the elliptical propellant cage, interfering with the infrared guidance sensors on missiles or fighter jets.

[0055] Simultaneously, the metal rope pulls the triangular metal plate 3, causing it and the connected lightweight air resistance membrane 4 to unfold. The unfolded triangular metal plate 3 can reflect or scatter radio waves, thereby interfering with the radio wave sensors on missiles and fighter jets in identifying combat targets. The lightweight air resistance membrane 4 generates drag, reducing the overall descent speed of the chaff and increasing its loiter time. Numerous chaff and flares provide cover for the aircraft releasing them to escape. The four triangular metal plates and the air resistance membrane form an umbrella-shaped structure.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
