Description

Technical Field

[0001] The present invention relates to the field of kinetic energy interceptors, and particularly to a multi-mode damage-enhanced kinetic energy interceptor. Background Art

[0002] With the rapid development of aerospace technology and the form of attack and defense, the targets of exoatmospheric penetrators are developing towards higher ranges, higher accuracies, and multi-target capabilities, which pose significant challenges to defense interception technologies. Mid-course kinetic energy interception technology, especially kinetic energy interception systems, has become a key technology that countries around the world are competing to develop. A kinetic energy interception system mainly consists of an interceptor, a propulsion system, a guidance system, etc. Currently, the interception mode of kinetic energy interceptors mainly relies on kinetic energy impact, that is, the interceptor directly impacts and damages the target through the kinetic energy generated by high-speed flight.

[0003] However, with the progress of penetrator technology, the flight speed has been significantly increased to 5000 - 6000 m / s, the target size has been reduced to 0.5 m - 1 m, and the penetrator has stronger multiple reentry vehicle (MRV) dispensing, protection, and maneuvering capabilities. This makes the existing single kinetic energy damage mode difficult to meet the "zero miss rate" required by current and future anti-missile systems. Therefore, there is an urgent need to develop new kinetic energy interceptor technologies with more efficient damage capabilities, more interception modes, and stronger integration characteristics. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-mode damage-enhanced kinetic energy interceptor to solve the technical problems of how to improve the damage ability of kinetic energy interceptors and how to increase the interception modes of kinetic energy interceptors.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A multi-mode damage-enhanced kinetic energy interceptor includes a central main shaft, and a guidance cabin, a control cabin, an interception cabin, an attitude and orbit adjustment cabin, and a tail cabin that are sequentially connected in series on the central main shaft along the axis direction of the central main shaft. The interception cabin includes a gas generation cabin and a discrete rod launch cabin. A first-stage aluminum film is provided between the gas generation cabin and the discrete rod launch cabin. The gas generation cabin is used to generate gas, and after the gas breaks through the first-stage aluminum film, it drives the discrete rod launch cabin to launch a plurality of radially diffused discrete rods forward.

[0007] Further, the discrete rod launch cabin includes a discrete rod launch tube, discrete rods, and fasteners. The discrete rod launch tube is a thin-walled tube provided on the outside of the discrete rod launch cabin and communicating with the inside of the discrete rod launch cabin. The discrete rods are cylindrical long rods placed inside the discrete rod launch tube, and the discrete rods are fixedly connected to the discrete rod launch tube through the fasteners.

[0008] Furthermore, multiple groups of discrete rod launch tubes are axially arranged on the outer side of the discrete rod launch cabin. Each group of discrete rod launch tubes includes multiple discrete rod launch tubes evenly distributed circumferentially. The axis of the discrete rod launch tube forms an angle with the axis of the discrete rod launch cabin, and the angle satisfies the following conditions: the launch density of the discrete rods is high, and the discrete rods do not interfere with each other.

[0009] Furthermore, the material of the discrete rod is an energetic high-entropy alloy.

[0010] Furthermore, the interception cabin further includes a telescopic rod launch cabin. The discrete rod launch cabin and the telescopic rod launch cabin are separated by a secondary aluminum film. After the gas breaks through the secondary aluminum film, it drives the telescopic rod launch cabin to deploy multiple telescopic rods radially diffused to its circumferential side.

[0011] Furthermore, the telescopic rod launch cabin includes a telescopic rod launch tube, a telescopic rod, and a sealing end cap. The telescopic rod launch tube is a thin-walled tube arranged on the outer side of the telescopic rod launch cabin and communicating with the inside of the telescopic rod launch cabin. The sealing end cap closes the port of the telescopic rod launch tube. The telescopic rod is a telescopic structure placed inside the telescopic rod launch tube. When the telescopic rod is impacted by gas, it can expand along the radial direction of the telescopic rod launch cabin.

[0012] Furthermore, each telescopic rod includes multiple telescopic tubes nested in sequence. Along the direction from near the interception cabin to far from the interception cabin, the radial dimension of each stage of telescopic tube decreases in sequence, and the end of the innermost telescopic tube far from the interception cabin is closed.

[0013] Furthermore, one end of each telescopic tube near the interception cabin expands outward, and one end of each telescopic tube far from the interception cabin contracts inward. After the telescopic rod expands, the expansion end of each telescopic tube squeezes the contraction end of another telescopic tube, thereby completing the self-locking of the telescopic rod through the plastic deformation of the telescopic tube.

[0014] Furthermore, the attitude and orbit adjustment cabin includes attitude and orbit engines and multiple gas nozzles. The tail cabin includes a gas tank. The gas nozzles are thin-walled tubes arranged on the outer side of the attitude and orbit adjustment cabin and connected to the gas tank through the attitude and orbit engines. The gas nozzles are evenly distributed around the axis of the attitude and orbit adjustment cabin. The attitude and orbit engines are used to connect the gas tank to different gas nozzles, thereby ejecting compressed gas moving radially to the outside of the attitude and orbit adjustment cabin, and then adjusting the attitude and orbit of the attitude and orbit adjustment cabin.

[0015] A multi-mode damage-enhanced kinetic energy interceptor, comprising a central main shaft, and along the axis direction of the central main shaft, a guidance cabin, a control cabin, an interception cabin, an attitude and orbit adjustment cabin, and a tail cabin are sequentially connected in series on the central main shaft. The interception cabin includes the gas generation cabin and the telescopic rod launch cabin. The gas generation cabin and the telescopic rod launch cabin are separated by a secondary aluminum film. The gas generation cabin is used to generate gas, and after the gas breaks through the secondary aluminum film, it drives the telescopic rod launch cabin to deploy a plurality of telescopic rods radially diffused to its peripheral side.

[0016] The present application has the following beneficial effects compared with the prior art:

[0017] A multi-mode damage-enhanced kinetic energy interceptor is provided. By designing a mechanism for launching discrete rods or telescopic rods on the interception cabin, the damage ability of the kinetic energy interceptor is improved, and the interception mode of the kinetic energy interceptor is increased.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The object of the present invention is to overcome the disadvantages of the single mode, small damage range and extremely high guidance accuracy requirements of kinetic interceptors in the prior art, and propose a new multi-mode damage-enhanced kinetic interceptor. This design combines multi-mode interception technology and active damage-enhancement technology, which can expand the damage range and density while significantly improving the damage effect by enhancing the aftereffect of damage, and finally achieve effective mid-course interception of penetration targets in a large area, high density, multi-level and multi-mode manner.

[0027] Specifically, in combination with Figures 1 to 4 , the multi-mode damage-enhanced kinetic interceptor includes a central main shaft, and along the axis direction of the central main shaft, the following are sequentially connected in series on the central main shaft: a guidance cabin 1, a control cabin 2, an interception cabin 3, an attitude and orbit adjustment cabin 4, and a tail cabin 5.

[0028] The central main shaft is used to provide structural strength and the function of arranging cables, so that the guidance cabin 1, the control cabin 2, the interception cabin 3, the attitude and orbit adjustment cabin 4 and the tail cabin 5 are firmly connected, and electricity and signals can be transmitted between each cabin.

[0029] The guidance cabin 1 is installed at the forefront of the kinetic interceptor and includes a communication module, a telemetry module and a guidance module. The communication module is used to receive external instructions and share data, and usually includes a data link and an antenna; the telemetry module undertakes the reception and transmission processing of internal and external data; the guidance module processes the guidance information from the guidance cabin 1 and completes the conversion of control instructions.

[0030] Regarding the specific structure of the guidance cabin 1: the telemetry module includes a radar, an infrared sensor and a laser rangefinder. Among them, the radar is used for long-range target detection and tracking, the infrared sensor is used for close-range target tracking, especially for the identification of heat sources (such as missiles), and the laser rangefinder provides high-precision target distance information; the guidance module includes a calculation and processing unit and an inertial satellite guidance module. Among them, the calculation and processing unit is responsible for real-time data processing, target state estimation and decision-making, and the inertial satellite guidance module is used to measure and maintain the self-positioning and direction of the interceptor.

[0031] The control cabin 2 includes a power supply and distribution module, a computing and processing module, a rudder control module, an instruction module, a control bus module, and a guidance processing module, which are responsible for the overall missile data processing, analysis, and instruction distribution. Among them, the power supply and distribution module is responsible for managing and distributing the power of all electrical equipment of the entire interceptor; the computing and processing module performs the calculation and processing of the ballistic and control information; the rudder control module is responsible for processing the attitude and trajectory engine control commands; the instruction module is responsible for collecting, processing, sending, and feedback of all instructions; the control bus module is responsible for coordinating the instruction transmission, attitude and trajectory control engine actions, and sensor data synchronization to ensure real-time attitude and trajectory control accuracy and system collaborative operation; the guidance processing module is responsible for real-time capturing, identifying, and tracking the target through multi-source sensors, and generating high-precision interception instructions by combining inertial measurement data and guidance algorithms. Through the collaborative work of these modules, the control cabin 2 can effectively control the interceptor to ensure accurate target interception.

[0032] The interception cabin 3 is a cylindrical thin-walled structure with a wall thickness of 3 mm, and the material is selected as magnesium-lithium alloy. The two ends of the interception cabin 3 are sealed end caps. The interior of the interception cabin 3 is divided into multiple chambers, namely a gas generation chamber 31, a discrete rod launch chamber 33, and a telescopic rod launch chamber 35. By selecting different chamber combinations, the following three alternative embodiments can be formed:

[0033] The first embodiment: The interception cabin 3 includes a gas generation chamber 31 and a discrete rod launch chamber 33, and the gas generation chamber 31 and the discrete rod launch chamber 33 are separated by a first-level aluminum film 32.

[0034] The second embodiment: The interception cabin 3 includes a gas generation chamber 31 and a telescopic rod launch chamber 35, and the gas generation chamber 31 and the telescopic rod launch chamber 35 are separated by a second-level aluminum film 34.

[0035] The third embodiment: The interception cabin 3 includes a gas generation chamber 31, a discrete rod launch chamber 33, and a telescopic rod launch chamber 35. The gas generation chamber 31 and the discrete rod launch chamber 33 are separated by a first-level aluminum film 32, and the discrete rod launch chamber 33 and the telescopic rod launch chamber 35 are separated by a second-level aluminum film 34.

[0036] The gas generation chamber 31 is used to generate gas and is the power source of the interceptor. A certain amount of low-explosion energetic material is fixed inside the gas generation chamber 31. A large amount of gas can be generated instantly when the low-explosion energetic material deflagrates. After accumulating pressure to a certain level inside the gas generation chamber 31, it breaks through the first-level aluminum film 32 and / or the second-level aluminum film 34 and enters the discrete rod launch chamber 33 and / or the telescopic rod launch chamber 35.

[0037] Among them, the low-explosion energetic material is excited by the ignition device. Parameters such as the dosage and detonation velocity of the low-explosion energetic material are strictly calculated to ensure that the generated air pressure is stable and controllable and does not cause damage to the self-structure of the gas generating chamber 31. The ignition device is connected to the integrated control system of the control cabin 2 through the control cable inside the central main shaft, and the excitation of the ignition device is controlled by the integrated control system.

[0038] The discrete rod launch chamber 33 is used to launch a plurality of radially diffused discrete rods 332 forward of itself, including a discrete rod launch tube 331, discrete rods 332, and fasteners. The discrete rod launch tube 331 is a thin-walled tube arranged on the outside of the discrete rod launch chamber 33 and communicating with the inside of the discrete rod launch chamber 33. The discrete rod 332 is a cylindrical long rod placed inside the discrete rod launch tube 331. The discrete rod 332 is fixedly connected to the discrete rod launch tube 331 through fasteners, so that the discrete rod 332 is kept in the initial position.

[0039] The material of the discrete rod launch tube 331 is selected as magnesium-lithium alloy, the outer diameter is selected as 20 mm, the wall thickness is selected as 2 mm, and the launch length is selected as 40 mm. Three groups of discrete rod launch tubes 331 are arranged axially along the outside of the interception chamber 3, and the spacing of each group of discrete rod launch tubes 331 is the same. Each group of discrete rod launch tubes 331 includes six discrete rod launch tubes 331 evenly distributed circumferentially.

[0040] The axis of the discrete rod launch tube 331 has a certain angle with the axis of the interception chamber 3. This angle is the launch angle of the discrete rod launch tube 331. The launch angles of different groups of discrete rod launch tubes 331 are different. The launch angles of the discrete rod launch tubes 331 are set through strict calculation. Under the condition of ensuring that the launched discrete rods 332 do not interfere with each other, the rod element density of the discrete rod interception curtain is increased to improve the interception accuracy of the interception target.

[0041] The material of the discrete rod 332 is selected as an energetic high-entropy alloy, the diameter is selected as 15 mm, the length is selected as 40 mm, and the fastener is selected as a fixed pin.

[0042] The telescopic rod launch chamber 35 is used to deploy a plurality of radially diffused telescopic rods 352 to the circumferential side of itself, including a telescopic rod launch tube 351, telescopic rods 352, and a sealing end cover 353. The telescopic rod launch tube 351 is a thin-walled tube arranged on the outside of the telescopic rod launch chamber 35 and communicating with the inside of the telescopic rod launch chamber 35. The telescopic rod 352 is a telescopic structure placed inside the telescopic rod launch tube 351. When the telescopic rod 352 is impacted by gas, it can expand along the radial direction of the interception chamber 3 to form a multi-claw interception structure. The maximum radius is 1.5 m, and the maximum distance between the telescopic rods 352 is 1.2 m, effectively improving the interception area and damage density.

[0043] The telescopic rod launch tube 351 and the telescopic rod 352 are made of magnesium-lithium alloy, and the quantity is 6. Each telescopic rod 352 includes a plurality of telescopic tubes nested in sequence. The telescopic tube is a pipe fitting with a wall thickness of 1 mm. The number of telescopic tubes included in each telescopic rod 352 is preferably 13. Along the direction from near the interception cabin 3 to far from the interception cabin 3, the radial dimensions of each stage of telescopic tube decrease in sequence, so that the 13 telescopic tubes can be nested and connected in sequence to form a telescopic structure.

[0044] One end of each telescopic tube near the interception cabin 3 expands outward, and one end of each telescopic tube far from the interception cabin 3 contracts inward. Among them, the end of the innermost telescopic tube far from the interception cabin 3 is closed. After the telescopic rod 352 is deployed, the expansion end of each telescopic tube squeezes the contraction end of another telescopic tube, so as to complete the self-locking of the telescopic rod 352 through the plastic deformation of the metal material, and keep the length of the telescopic rod 352 by itself without external force.

[0045] The sealing cover is an aluminum diaphragm installed at the port of the telescopic rod launch tube 351, which plays the role of sealing and fixing the telescopic rod 352 in the initial state.

[0046] The attitude and orbit adjustment cabin 4 is used to adjust the attitude and orbit of the multi-mode damage-enhanced kinetic energy interceptor. The attitude and orbit adjustment cabin 4 includes attitude and orbit engines and a plurality of gas nozzles 41. The tail cabin 5 includes a battery and a gas tank. The gas nozzles 41 are thin-walled tubes arranged on the outside of the attitude and orbit adjustment cabin 4 and communicated with the gas tank through the attitude and orbit engines. The number of gas nozzles 41 is preferably 4, and the gas nozzles 41 are evenly distributed around the axis of the attitude and orbit adjustment cabin 4. The attitude and orbit engines are used to connect the gas tank to different gas nozzles 41, so as to spray compressed gas moving radially outward to the multi-mode damage-enhanced kinetic energy interceptor, so as to adjust the attitude and orbit of the multi-mode damage-enhanced kinetic energy interceptor.

[0047] Taking the third embodiment as an example below, the working principle of the multi-mode damage-enhanced kinetic energy interceptor is described in detail.

[0048] First, detection devices such as ground-based, sea-based or air-based early warning radars search for potential threat targets, and initially determine their approximate azimuth, speed, flight trajectory and other information; the command and control system analyzes, processes and fuses this information, and further accurately calculates the flight parameters of the target, such as orbit, expected arrival time, etc.; at the same time, the command and control system will sort according to the target threat level and formulate corresponding interception strategies; the command and control system selects a suitable kinetic energy interceptor launch unit according to the target information and interception strategy, and issues a launch command; the kinetic energy interceptor is ignited and launched according to the predetermined procedure, and quickly ascends with the thrust of the rocket engine.

[0049] Subsequently, the following steps are executed:

[0050] Step 1: The kinetic energy interceptor relies on the inertial navigation system for navigation, adjusts its flight attitude and direction according to the pre-flight parameters, and flies towards the general direction of the target. After the kinetic energy interceptor enters the mid-course flight stage, it mainly adopts a guidance method that combines the inertial navigation system and the satellite navigation system (inertial satellite guidance module) to further accurately control the flight trajectory of the kinetic energy interceptor. At the same time, the radar, infrared sensor, and laser rangefinder start to work to conduct autonomous search and tracking of the target.

[0051] Step 2: When approaching the target, the kinetic energy interceptor releases a multi-mode damage-enhanced kinetic energy interceptor. The multi-mode damage-enhanced kinetic energy interceptor receives the target indication information from the ground through the communication module and simultaneously receives the target indication information through the telemetry module, and then transmits the target information to the guidance module. The calculation and processing module of the guidance module conducts the planning of the trajectory and guidance, corrects the trajectory in the intersection section, and then manipulates the attitude and trajectory engine through the comprehensive control system to eject gas using different gas nozzles 41 to achieve attitude adjustment. Finally, the multi-mode damage-enhanced kinetic energy interceptor flies according to the corrected trajectory, thereby shortening the spatial distance from the target.

[0052] Step 3: When the distance from the target is less than the specified distance (for example, 100 m), the comprehensive control system sends an ignition command, and the ignition device stimulates the deflagration of the low-explosion energetic material to generate a large amount of gas, and accumulates pressure in the gas generation chamber 31 to form a certain pressure.

[0053] The compressed gas breaks through the first-stage aluminum film 32 and enters the discrete rod launch chamber 33. The compressed gas forms a driving pressure in the discrete rod launch tube 331. When the air pressure exceeds a certain value, the fixing pin is cut off, and the discrete rod 332 is launched at a certain initial velocity under the driving force, forming a discrete rod 332 interception curtain around the interceptor. The maximum radius is 2.4 m. The discrete rod 332 made of energetic high-entropy alloy penetrates the target shell and produces damage after-effects, causing structural damage and functional damage to the target by releasing chemical energy.

[0054] At this time, although the compressed air inside the discrete rod launch chamber 33 overflows through the discrete rod launch tube 331, the rate of gas generation when the low-burning gunpowder burns rapidly is greater than the rate of gas overflow. Therefore, the compressed gas can still accumulate pressure inside the discrete rod launch chamber 33, break through the second-stage aluminum film 34 and enter the telescopic rod launch chamber 35. The compressed gas forms a driving pressure in the telescopic rod launch tube 351. When the air pressure exceeds a certain value, the sealing cover is broken through, and the telescopic rod 352 is deployed at a certain initial velocity under the driving force. After deployment, it becomes a multi-claw interception structure, and the kinetic energy of the body of the multi-mode damage-enhanced kinetic energy interceptor and the telescopic rod 352 is used to cause structural damage to the target.
