The midcourse kinetic energy interception technology, especially the kinetic energy interception system, has become a key technology that countries around the world are competing to develop. The kinetic energy interception system mainly consists of an interceptor, a propulsion system and a guidance system. At present, the interception mode of the kinetic energy interceptor mainly relies on kinetic energy impact, that is, the kinetic energy generated by the high-speed flight of the interceptor directly impacts and damages the target.

A certain amount of low-explosive energetic material is fixed inside the gas generating cabin 31. A large amount of gas can be generated in the moment of deflagration of the low-explosive energetic material. After a certain pressure is accumulated in the gas generating cabin 31, the first aluminum film 32 and / or the second aluminum film 34 is broken, and the gas enters the discrete rod launching cabin 33 and / or the extension rod launching cabin 35.

[0037] The low-explosive energetic material is excited by the ignition device, and the amount and the detonation velocity of the low-explosive energetic material are strictly calculated to ensure that the generated gas pressure is stable and controllable and does not cause the self-structure of the gas generating cabin 31 to be damaged, and the ignition device is connected with the control system of the control cabin 2 through the control cable in the central main shaft, and the ignition of the ignition device is controlled by the control system.

[0038] The discrete rod launching cabin 33 is used for launching a plurality of radially diffused discrete rods 332 to the front of itself, and includes a discrete rod launching tube 331, a discrete rod 332 and a fastener, the discrete rod launching tube 331 is a thin-walled tube arranged on the outer side of the discrete rod launching cabin 33 and connected with the inside of the discrete rod launching cabin 33, the discrete rod 332 is a cylindrical long rod placed in the discrete rod launching tube 331, and the discrete rod 332 is fixedly connected with the discrete rod launching tube 331 through the fastener, so that the discrete rod 332 is kept in the initial position.

[0039] The material of the discrete rod launching tube 331 is selected to be magnesium-lithium alloy, the outer diameter is selected to be 20 mm, the wall thickness is selected to be 2 mm, and the launching length is selected to be 40 mm, and the discrete rod launching tube 331 is arranged axially on the outer side of the interception cabin 3 in three groups, the spacing of each group of discrete rod launching tubes 331 is the same, and each group of discrete rod launching tubes 331 includes six discrete rod launching tubes 331 uniformly distributed in the circumferential direction.

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

[0042] The telescopic rod launching cabin 35 is used for launching a plurality of radially diffused telescopic rods 352 to the side of itself, and includes a telescopic rod launching tube 351, a telescopic rod 352 and a sealing end cover 353, the telescopic rod launching tube 351 is a thin-walled tube arranged on the outer side of the telescopic rod launching cabin 35 and connected with the inside of the telescopic rod launching cabin 35, the telescopic rod 352 is a telescopic structure placed in the telescopic rod launching tube 351, and the telescopic rod 352 can be unfolded along the radial direction of the interception cabin 3 when impacted by the gas to form a multi-claw-shaped interception structure, the maximum radius is 1.5 m, and the maximum spacing between the telescopic rods 352 is 1.2 m, so as to effectively improve the interception area and damage density.

[0043] The telescopic rod launching tube 351 and the telescopic rod 352 are made of magnesium-lithium alloy, and the number of the telescopic rod 352 is 6. Each telescopic rod 352 comprises a plurality of telescopic tubes which are nested one by one. The telescopic tube is a pipe with a wall thickness of 1 mm. The number of the telescopic tubes included in each telescopic rod 352 is preferably 13. In the direction from the intercepting cabin 3 to the direction away from the intercepting cabin 3, the radial dimension of each telescopic tube decreases in turn, so that the 13 telescopic tubes can be connected in turn to form a telescopic structure.

[0044] Each telescopic tube is expanded outward at one end close to the intercepting cabin 3, and is contracted inward at the other end away from the intercepting cabin 3. The innermost telescopic tube is closed at the end away from the intercepting cabin 3. When the telescopic rod 352 is unfolded, the expanded end of each telescopic tube presses the contracted end of another telescopic tube, so that the telescopic rod 352 is self-locked through plastic deformation of the metal material, and the telescopic rod 352 maintains its length without external force.

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

The number of the gas nozzle 41 is preferably 4. The gas nozzles 41 are uniformly distributed around the axis of the attitude and orbit adjustment cabin 4. The attitude and orbit engine is used to connect the gas tank to different gas nozzles 41, so as to spray compressed gas moving radially to the outside of the multi-mode damage-enhanced kinetic energy interceptor, thereby adjusting the attitude and orbit of the multi-mode damage-enhanced kinetic energy interceptor.

[0047] Hereinafter, the working principle of the multi-mode damage-enhanced kinetic energy interceptor will be described in detail taking the third embodiment as an example.

[0048] Firstly, the early warning radar and other detection devices based on land, sea or air search for potential threat targets, and preliminarily determine the approximate position, speed and flight trajectory and other information of the targets. The command and control system analyzes, processes and fuses these information, and further accurately calculates the flight parameters of the targets, such as the orbit and the estimated time of arrival. At the same time, the command and control system sorts the targets according to the threat degree, and formulates the corresponding interception strategy. The command and control system selects the appropriate kinetic energy interceptor launching unit according to the target information and the interception strategy, and issues the launching instruction. The kinetic energy interceptor is ignited and launched according to the predetermined program, and rapidly ascends by means of the thrust of the rocket engine.

[0049] Subsequently, the following steps are performed:

[0050] Step one, the kinetic energy interceptor relies on inertial navigation system for navigation, according to the pre-flight parameters to adjust the flight attitude and direction, roughly to the target direction; when the kinetic energy interceptor enters the middle flight phase, mainly using inertial navigation system and satellite navigation system combined (inertial navigation module) guidance mode, further control the flight trajectory of the kinetic energy interceptor; at the same time, radar, infrared sensor, laser range finder start work, the target for independent search and tracking.

[0051] Step two, when approaching the target, the kinetic energy interceptor releases multi-mode damage enhanced kinetic energy interceptor, multi-mode damage enhanced kinetic energy interceptor through the communication module to accept the ground target indication information, at the same time through the telemetry module to receive target indication information, then the target information is transmitted to the guide module, the guide module of the computing processing module for trajectory and guidance planning work, correction intersection trajectory, then through the integrated control system to control the attitude and orbit engine using different gas jet 41 to jet gas, realize the attitude adjustment, finally make the multi-mode damage enhanced kinetic energy interceptor fly according to the corrected trajectory, so as to shorten the space distance with the target.

[0052] Step three, when the distance with the target is less than the specified distance (for example, 100m), the integrated control system sends the ignition instruction, the ignition device stimulates the low explosive energetic material deflagration to produce a large amount of gas, and forms a certain pressure in the gas generating cabin 31.

[0053] The compressed gas breaks through the first aluminum film 32 into the discrete rod launching cabin 33, and the compressed gas forms a driving pressure in the discrete rod launching tube 331. When the gas pressure exceeds a certain value, the fixed pin is sheared off, and the discrete rod 332 is launched at a certain initial speed under the action of the driving force, forming a discrete rod 332 interception screen around the interceptor with a maximum radius of 2.4m. The discrete rod 332 made of energetic high-entropy alloy penetrates the target shell and produces damage aftereffect, causing structural damage and functional damage to the target by releasing chemical energy.

[0054] At this time, although the compressed air in the discrete rod launching cabin 33 leaks through the discrete rod launching tube 331, the rate of gas produced by the rapid combustion of low-burning fire powder is greater than the rate of gas leakage, so the compressed gas can still accumulate pressure in the discrete rod launching cabin 33, break through the second aluminum film 34 into the telescopic rod launching cabin 35, and the compressed gas forms a driving pressure in the telescopic rod launching tube 351. When the gas pressure exceeds a certain value, the sealing cover is broken, and the telescopic rod 352 is unfolded at a certain initial speed under the action of the driving force. After unfolding, it becomes a multi-claw-shaped interception structure, which uses the kinetic energy of the multi-mode damage enhanced kinetic energy interceptor and the telescopic rod 352 to damage the target structure.
