Description

Technical Field

[0001] The present invention relates to the technical field of aircraft equipment, and in particular to an air missile interception parachute, an interception method and a fighter jet. Background Art

[0002] When a fighter is locked by an enemy guided missile, the missile will calculate the fighter's flight trajectory in real time based on the aircraft's speed and direction, adjust the missile's flight direction accordingly, and plan the position where the missile hits the fighter. At this time, the pilot usually needs to adjust the fighter's flight attitude or increase the fighter's flight speed to consume the enemy's guided missile's energy during the pursuit process until the enemy missile's energy is exhausted and loses its tracking ability, thus escaping from danger.

[0003] However, the flight speed and maneuverability of guided missiles are often far superior to those of aircraft. Breaking free from the missile's lock by consuming the missile's energy requires very high maneuverability of the aircraft, and the success rate of breaking free from the missile's lock is low.

[0004] The existing methods for fighter jets to evade missiles include equipping chaff bombs or towing decoys to guide missiles, but these methods produce limited interference signals and short air time, and the effect of protecting fighter jets and pilots is not ideal. Therefore, there is an urgent need for an air missile interception parachute and interception method to improve the success rate of fighter jets getting rid of missile locks. Summary of the invention

[0005] The main purpose of the present invention is to provide an air missile interception parachute, an interception method and a fighter jet, so as to improve the success rate of the fighter jet in escaping missile lock.

[0006] The technical solution adopted by the present invention is: an air missile interception parachute, comprising a parachute, a signal interference generator and a parachute cabin; wherein the parachute is connected to the parachute cabin, and the signal interference generator is installed in the parachute cabin;

[0007] When the fighter is not locked by the missile, the parachute compartment is placed in the fighter, and the parachute is placed in the parachute compartment; when the fighter is locked by the missile, the parachute compartment is ejected from the fighter, the parachute is detached from the parachute compartment, fully inflated, and the signal interference generator simulates and transmits the fighter signal.

[0008] Preferably, the parachute comprises a canopy, a reinforcing belt and a parachute rope; the reinforcing belt is distributed on the canopy, one end of the parachute rope is connected to the canopy, corresponding one-to-one to the reinforcing belt, and the other end is connected to the parachute cabin.

[0009] Preferably, the reinforcement bands are evenly distributed on the canopy along the circumference of the canopy, and each reinforcement band is arranged radially.

[0010] Preferably, a metal wire is fixed on the reinforcement belt to increase the strength of the canopy and block signals.

[0011] Preferably, a connecting belt is provided between the parachute and the parachute cabin, and the connecting belt is connected to the parachute rope.

[0012] Preferably, the parachute cabin includes: a signal generating cabin in which a signal jammer generator is installed; a parachute launching cabin located above the signal generating cabin; a launching cover located above the parachute launching cabin and connected to the parachute launching cabin by bolts; and a hanging interface located at the bottom of the parachute launching cabin, which is connected to the connecting belt.

[0013] Preferably, the intercepting parachute also includes a canopy cover, one end of which is connected to the launching cover, and when the fighter is not locked by the missile, the other end of the canopy cover wraps the parachute and is stored in the launching cabin together with the parachute.

[0014] Preferably, when the fighter is locked by the missile, the process of the parachute escaping from the parachute cabin specifically includes: after the parachute cabin is ejected from the fighter, the bolts on the release cover separate the release cover and the parachute cabin, and as the distance between the release cover and the parachute cabin increases, the canopy cover and the parachute inside are gradually straightened, and finally the canopy cover leaves the parachute along with the release cover.

[0015] The present invention also provides an air missile interception method, which is based on the above-mentioned air missile interception parachute, and includes: when it is determined that the fighter plane itself is locked by the missile, changing the fighter plane's flight attitude and ejecting the interception parachute from the tail;

[0016] After the intercepting parachute is ejected by the fighter jet, the parachute is released from the parachute compartment and fully inflated, and the signal interference generator simulates and sends out a fighter jet signal.

[0017] The present invention also provides a fighter jet, which executes the above-mentioned air missile interception method.

[0018] The beneficial effects produced by the present invention are:

[0019] 1. The air missile interception parachute of the present invention includes a parachute, a signal jammer and a parachute cabin. When a fighter is locked by a missile, the fighter changes its flight attitude and launches an interception parachute. The interception parachute opens in the air and emits a simulated jamming signal to induce the missile to preferentially attack the interception parachute. If the jamming signal fails to successfully play an interference role, the interception parachute can still play a physical interception role between the missile and the fighter. The present invention adds a barrier for the fighter to avoid missile attacks, further protecting the safety of the pilot.

[0020] 2. A reinforcing belt for internally fixing metal wires is provided in the canopy of the air missile interception parachute of the present invention. While increasing the strength of the canopy, the metal wires can generate resonance blocking signals to further interfere with the missile.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example 1

[0037] This embodiment provides an air missile interception parachute, which is arranged in an interception device at the tail of a fighter 7, and includes a parachute 1, a signal interference generator 3 and a parachute compartment 5. The parachute 1 is connected to the parachute compartment 5, and the signal interference generator 3 is installed in the parachute compartment 5.

[0038] When the fighter 7 is not locked by the missile 8, the structure of the interception parachute 9 is as follows Figure 5 As shown, the parachute compartment 5 is placed in the interception device at the tail of the fighter 7, and the parachute 1 is placed in the parachute compartment 5. When the fighter 7 is locked by the missile 8, the structure of the interception parachute 9 is as shown in FIG. Figure 2 As shown, the parachute compartment 5 is ejected from the interception device at the tail of the fighter 7, the parachute 1 escapes from the parachute compartment 5, and is fully inflated during the falling process, and the signal interference generator 3 simulates and emits the signal of the fighter 7 to interfere with the missile 8.

[0039] Furthermore, the parachute 1 further comprises a canopy 101, a reinforcement belt 102 and a parachute rope 103, such as Figure 3The canopy 101 is unfolded and laid flat. The canopy 101 is circular. The reinforcing belts 102 are evenly distributed on the canopy 101 along the circumferential direction. At the same time, each reinforcing belt 102 is radially distributed on the canopy 101, that is, one end of each reinforcing belt 102 is arranged at the center of the canopy 101, and the other end is arranged at the outer edge of the canopy 101. One end of the parachute rope 103 is also connected to the edge of the canopy 101, corresponding to the reinforcing belt 102 one by one, and the other end of the parachute rope 103 forms a rope loop through the suture.

[0040] Furthermore, a metal wire 2 is fixed inside the reinforcing belt 102 to increase the strength of the canopy 101 and block the signal, which can further interfere with the missile 8 on the basis of the signal interference generator 3.

[0041] Furthermore, the intercepting parachute 9 also includes a connecting belt 4 provided between the parachute 1 and the parachute compartment 5, such as Figure 4 As shown, one end of the connecting belt 4 is connected to the rope loop formed by the parachute rope 103.

[0042] Furthermore, the parachute cabin 5 includes a signal generating cabin 504, a parachute releasing cabin 502, a jettison cover 503 and a hanging interface 501. The signal generating cabin 504 is located at the bottom of the parachute cabin, and a signal interference generator 3 is installed inside. The parachute releasing cabin 502 is arranged above the signal generating cabin 504, and a hanging interface 501 connected to the connecting belt 4 is installed at the bottom, and the parachute releasing cabin 502 is not connected to the signal generating cabin 504. A jettison cover 503 is arranged on the top of the parachute releasing cabin 502, and is connected to the parachute releasing cabin 502 by bolts, and the bolts can separate the jettison cover 503 and the parachute releasing cabin 502 when working.

[0043] Furthermore, the intercepting parachute 9 also includes a canopy cover 6, such as Figure 6 As shown, one end of the canopy cover 6 is connected to the launching cover 503 , and when the fighter 7 is not locked by the missile 8 , the other end of the canopy cover 6 wraps the parachute 1 and is stored together with the parachute 1 in the launching compartment 502 .

[0044] Furthermore, when the fighter 7 is locked by the missile 8, the process of the parachute 1 escaping from the parachute compartment 5 specifically includes: after the parachute compartment 5 is ejected from the fighter 7, the bolts on the release cover 503 separate the release cover 503 and the parachute compartment 5, and as the distance between the release cover 503 and the parachute compartment 5 increases, the canopy cover 6 and the parachute 1 inside are gradually straightened under the action of airflow resistance, and finally the canopy cover 6 connected to the release cover 503 leaves the parachute 1 along with the release cover 503, and the parachute 1 connected to the parachute compartment 502 completes its escape from the canopy cover 6 and begins to inflate.

[0045] Furthermore, from the assembly structure of the various components in the above-mentioned interception parachute 9, it can be known that the air missile interception parachute works in the following circumstances: when the fighter 7 is not locked by the missile 8, the canopy 6 wraps the parachute 1 and is stored in the parachute compartment 502, the signal interference generator 3 does not generate or emit interference signals, and the interception parachute 9 is placed as a whole in the interception device at the tail of the fighter 7.

[0046] When the fighter 7 is locked by the missile 8, the interception parachute 9 is ejected from the tail of the fighter 7, the signal interference generator 3 starts to generate and transmit interference signals, and the bolts on the release cover 503 separate the release cover 503 and the parachute compartment 5, as shown in Figure 7 (a). Due to the wind resistance, the parachute 1 and the canopy cover 6 are straightened in the air, and then the parachute 1 is removed from the canopy cover 6, as shown in Figure 7 (b), and the canopy 101 is gradually inflated and fully expanded. After the canopy 101 is fully expanded, the interception parachute 9 begins to slowly descend, separating between the fighter 7 and the missile 8, and performing signal interference or physical interception. Among them, the interception parachute 9 preferably performs signal interference. If the signal interference effect is not good, it can play a role of physical interception by relying on a larger umbrella surface area.

[0047] Example 2

[0048] This embodiment provides an air missile interception method, which is applied to the situation where a fighter 7 is locked by a missile 8 in the air. Figure 1 As shown, the air missile interception parachute described in Example 1 is used in this method.

[0049] The content of this method includes: when it is determined that the fighter 7 is locked by the missile 8, the fighter 7 changes its flight attitude and launches the interception parachute 9 from the tail. When the interception parachute 9 is launched from the interception device at the tail of the fighter 7, the parachute 1 escapes from the parachute compartment 5, is fully inflated, and the signal interference generator 3 simulates and sends out the signal of the fighter 7. The process of this method is as follows Figure 8 shown.

[0050] Specifically, the missile 8 predicts the predicted position 10 of the aircraft after a period of time based on the flight direction and flight speed of the fighter 7, and then attacks. Based on the attack principle of the missile 8, when the aircraft finds itself locked by the missile 8 and is ready to attack, it shoots out the interception parachute 9 from the tail while changing its flight attitude. The interception parachute 9 opens in the air, and due to the existence of air resistance, the interception parachute 9 descends at a relatively low speed, and remains in the same straight line with the fighter 7 and the missile 8, serving as a barrier to block the fighter 7 and the missile 8. At the same time, the interception parachute 9 with a larger target sends out an interference signal simulating the fighter 7, inducing the missile 8 to attack itself to complete the interception. Furthermore, if the interference signal does not work, the interception parachute 9 located between the fighter 7 and the missile 8 has a larger area and can still physically intercept the missile 8.

[0051] Example 3

[0052] This embodiment provides a fighter jet 7, which executes the air missile interception method described in Embodiment 2, and is equipped with an interception device at the tail, in which the air missile interception parachute described in Embodiment 1 is equipped.

[0053] In summary, the air missile interception parachute, interception method and fighter provided by the present invention have an interception device arranged at the tail of the fighter, which launches an interception parachute to intercept the missile through interference signals and physical interception. When the fighter is locked by the missile, a barrier is added between the fighter and the missile, thereby protecting the safety of the pilot.

[0055] The order of execution of each step in the above embodiment does not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.
