Description

Technical Field

[0001] This application relates to the field of electromagnetic launch technology, and more specifically, to a multifunctional segmented acceleration rail electromagnetic gun. Background Technology

[0002] Traditional electromagnetic launch technology is a new type of launch technology that can accelerate the launcher to ultra-high speed. It uses electromagnetic force to drive the payload and converts electromagnetic energy into the kinetic energy of the launcher, which can accelerate a variety of objects including projectiles, shells, missiles, and aircraft.

[0003] According to literature, the history of electromagnetic weapons can be traced back to at least 1916, with the actual use of electromagnetic force to launch objects occurring at Princeton University in the United States in 1937. After the 1970s, major world powers such as China, the United States, and Russia successively recognized the enormous development potential of electromagnetic launch technology and included electromagnetic guns (guns) in their future weapons development plans. With the increasing maturity of electromagnetic theory and materials science, modern electromagnetic launch technology possesses advantages such as high energy density, high initial velocity, long range, simple power source, and low launch cost. However, currently, this technology is primarily used in the military field, manifested in individual electromagnetic guns, shipborne electromagnetic guns, and shipborne aircraft catapults. As electromagnetic launch technology enters the ranks of cutting-edge military weapons technology, it will inevitably enter the civilian equipment field due to its increasingly mature theoretical level and manufacturing standards. This also means that once this technology is efficiently, practically, and marketably transferred from military to civilian use, the application level of electromagnetic theory will reach a completely new level, and the market for related fields will open up significantly.

[0004] my country's electromagnetic launch technology started relatively late, but its research intensity has been rising year by year over the past decade, especially in electromagnetic rail launch technology, which has maintained a continuous growth momentum. Electromagnetic launch technology research involves expertise in magnetism, mechanics, materials, circuit design, and signal processing. The most common classification method is based on the acceleration method (or launch structure), dividing the finished product—electromagnetic guns (guns) or other launching devices—into coil type (including special coil types, i.e., reconnected types) and rail type. Because coil-type electromagnetic guns (guns) face the problem of matching the phase of the alternating current with the velocity of the launcher, the requirements for the supplied alternating current are extremely high, the launcher compatibility is poor, and the production cost is higher than that of rail-type electromagnetic guns (guns), making them unsuitable for lightweighting and civilian application. Therefore, this invention focuses on optimizing, upgrading, and innovating traditional rail-type electromagnetic gun (gun) launching technology (including the design of the magnetization method and magnetization circuit). Summary of the Invention

[0011] Furthermore, the electromagnet assembly is disposed between the connecting post and the guide rail body, including a loading electromagnet and a trigger switch, wherein: the trigger switch is disposed in the wire hole of the connecting post and is connected to the guide rail power supply via a spring and a wire; the loading electromagnet is disposed in the mounting hole at the rear end of the guide rail body and is controlled by the trigger switch.

[0012] Furthermore, the launch carrier is cross-shaped, and the upper and lower parts can be separated by the attraction of the upper electromagnet.

[0013] Furthermore, the guide rail circuit is a magnetic supply circuit composed of multiple rows of "I"-shaped iron cores connected together.

[0033] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings.

[0034] In addition, the term "multiple" should mean two or more.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 2-4As shown, this application provides a multifunctional segmented acceleration rail electromagnetic gun, including a main power magazine 1, a stock 2, a gun body mechanism 3, a bolt mechanism 4, a magazine device 5, a rail power magazine 6, a rail body 7, and a launching carrier 8, wherein: the stock 2 is detachably mounted on top of the main power magazine 1; the main power magazine 1 is connected to one end of the gun body mechanism 3 for power supply; the other end of the gun body mechanism 3 is connected to the bolt mechanism 4; the magazine device 5 is magnetically attached to the bottom of the bolt mechanism 4 for loading ammunition; one end of the rail power magazine 6 is connected to the bolt mechanism 4, and the other end is connected to the rail body 7 via a connecting post 9; one end of the rail body 7 is provided with an electromagnet assembly, and the other end is nested with a blocking block 73; the rail body 7 has a rail circuit 71 inside and an electromagnetic shielding layer 72 outside; the launching carrier 8 can slide along the rail circuit 71 of the rail body 7 to propel the ammunition for launching.

[0037] Specifically, such as Figure 1 As shown, a traditional rail-mounted electromagnetic gun launching mechanism consists of a long, straight metal rail, a launcher, an armature, and a pulse power supply. The power supply comprises a capacitor bank and a pulse forming network, capable of generating instantaneous, high-current pulses. During launch, current flows through the rail, and a high-voltage arc heats the armature to a plasma state, forming a closed loop through the conductive launcher (or launcher + armature). At this point, the current on the rail passes perpendicularly through the magnetic field of the rail plane. The launcher (or launcher + armature) carrying the current experiences a strong Lorentz force in this magnetic field and slides along the rail axis, thus completing the launch. The magnitude of the applied Lorentz force is proportional to the square of the current and the effective length of the rail. However, existing technologies have a narrow target audience, limited applications, high manufacturing costs, and cannot be used for multi-mission applications. They are generally only suitable for military use, and existing technologies suffer from significant energy dissipation, relatively complex manufacturing processes, and poor environmental tolerance. The multifunctional segmented acceleration rail electromagnetic gun provided in this application uses an optimized transformer electromagnetization method instead of the traditional rail instantaneous high current magnetization method. A single-chip microcomputer is used to control the magnetization zone to achieve staged acceleration to control the muzzle velocity of the launcher. Separate launch magnetic field and recovery magnetic field are used to complete the rapid recovery of the launch carrier 8. The launch carrier 8 with strong compatibility can complete the launch mission of different launchers. A simpler circuit structure is adopted, which improves product reliability and reduces costs. The new magnetization method and staged acceleration method can reduce the waste of electrical energy.

[0038] More specifically, in this embodiment, the main power supply unit 1 is primarily used to house the power supply battery. Multiple wires are led out from the battery and connected to various power-consuming modules through wire holes 10. These wires supply power to the microcontroller, the magnetic circuit of the guide rail, and other power-consuming modules. The main power supply unit 1 also has ample space for different upgrade designs based on actual needs, supplying power to newly added modules, such as an ambient temperature and humidity detection module or a muzzle velocity limiting resistor. The stock 2 is detachably mounted on top of the main power supply unit 1, and can be installed using magnetic adsorption or a snap-on mechanism, depending on the actual situation. The stock 2 mainly covers and protects the power supply battery inside the main power supply unit 1. The gun body mechanism 3, bolt mechanism 4, and magazine device 5 work together, mainly for loading, filling, and firing ammunition. The gun body mechanism 3 allows for control of the muzzle velocity. The guide rail power supply unit 6 primarily supplies power to the guide rail body 7, providing it with drive current. It can also serve as a backup power source; when the main power supply unit 1 fails, power can be supplied through the guide rail power supply unit 6. The guide rail body 7 has a guide rail circuit 71 inside, which is mainly composed of a magnetic supply circuit connected by an iron core. Under the action of magnetic force, the launch carrier 8 can push the ammunition to move in the guide rail circuit 71. The blocking block 73 is mainly used to block the launch carrier 8 and prevent the launch carrier 8 and the ammunition from being fired together. The blocking block 73 is fixed to the end of the guide rail by welding, nesting or adhesive according to the actual situation. In addition, a buffer material, such as sponge, can be set between the blocking block 73 and the launch carrier 8, which mainly plays a buffering role and prevents the blocking block 73 from being damaged by repeated impacts from the launch carrier 8.In this embodiment, during use, ammunition is first placed in the magazine 5, and then chambered via the bolt mechanism 4. During chambering, the electromagnet assembly at one end of the guide rail body 7 is triggered, causing the firing carrier 8 to separate vertically. At this time, under the action of the bolt mechanism 4, the ammunition enters the gun body mechanism 3 from the magazine 5, and passes sequentially through the bolt mechanism 4, the guide rail power magazine 6, and the connecting post 9, entering one end of the guide rail body 7. Since the firing carrier 8 is separated vertically, the ammunition moves to the front of the firing carrier 8. At this time, the bolt mechanism 4 is released, the magazine 5 is blocked, the firing carrier 8 closes vertically, and the ammunition is located directly in front of the firing carrier 8. During firing, pulling the grip 32 of the gun body mechanism 3 generates current in the guide rail circuit 71. This creates a magnetic field. Under the influence of the magnetic field, the launching carrier 8 propels the ammunition in front of it to move rapidly to the other end of the guide rail body 7. When it reaches the end of the guide rail body 7, the ammunition is ejected and launched directly. The launching carrier 8 is stopped by the blocking block 73 and will not fly out with the ammunition. Then, by controlling the trigger of the gun body mechanism 3, the corresponding magnetic supply circuit that provides the driving magnetic field is closed, and another part of the magnetic supply circuit with the opposite magnetic supply direction is opened. This allows an electromagnetic force to be obtained on the launching carrier 8 in the opposite direction to that during launch. This force can be used to reset the launching carrier 8, thus completing one round of ammunition loading and firing. During the firing process, the various parameters of the guide rail circuit 71 can be set through the gun body mechanism 3 to control the muzzle velocity of the ammunition.

[0039] Furthermore, the gun mechanism 3 includes a gun body 31, a grip 32, a microcontroller compartment 33, a protective cover 34, and a display screen 35. Specifically: the grip 32 is fixed to the bottom of the gun body 31; one end of the gun body 31 is connected to the main power supply compartment 1, and the other end has a firing port with wire holes 10 on both sides; the microcontroller compartment 33 is located inside the gun body 31 and is used to house the microcontroller; the protective cover 34 covers the top of the microcontroller compartment 33 to protect the microcontroller, and has wire grooves on the protective cover 34; the display screen 35 is fixedly fastened to the protective cover 34 and connected to the microcontroller via wires in the wire grooves; the microcontroller is also connected to the main power supply compartment 1 via wires in the wire holes 10. The grip 32 has a trigger. When in use, the hand grips the grip 32 and pulls the trigger. The trigger is mainly used to control the firing of ammunition and the resetting of the firing carrier 8, essentially acting as a control switch. Depending on the actual situation, the grip 32 trigger can be configured with different functions. In this embodiment, the preferred microcontroller is the STC89C52. The microcontroller is placed in the microcontroller compartment 33, and after the protective cover 34 is closed, a wire can be used to lead out the display screen 35, function buttons, etc. By adjusting the microcontroller (controlling the number of effective magnetic circuits on the guide rail by controlling the independent magnetic supply circuit switch), the effective acceleration distance and the magnitude of the acceleration magnetic field can be controlled, thereby adjusting the muzzle velocity of the projectile. The display screen 35 can display the specific firing speed, other product functions (such as displaying the remaining ammunition quantity), or the environmental conditions.

[0040] Furthermore, the bolt mechanism 4 includes a connecting body 41, a bolt 42, and a push rod 43. The bolt 42 is located on the side of the connecting body 41 and is integrally formed with it. A firing tube is mounted on the connecting body 41, and wire holes 10 are provided on both sides of the firing port. The push rod 43 is fixedly mounted inside the firing tube and is connected to the firing port on the gun body 31 via a positioning spring. Pulling the bolt 42 moves the connecting head backward and compresses the positioning spring. A spring groove is provided above the firing tube, connecting it to the guide rail power magazine 6, and the lower part of the firing tube is connected to the magazine device 5. The firing tube is mainly used for firing ammunition, the wire holes 10 on both sides are used to hold wires led from the main power magazine 1, and the push rod 43 is used to push the ammunition inside the firing tube. The bolt mechanism 4 is mainly used for loading ammunition. When loading, the bolt 42 is pulled back manually or by spring traction, which pulls the cylindrical push rod 43 back. The space left can activate the changing spring in the automatic magazine 53, which is connected to the multi-functional magazine 52. This spring pushes the ammunition upward to fill the previously left space, allowing the ammunition to enter the bolt mechanism 4. Then, the bolt 42 is pulled forward manually or by spring traction, which can activate the electromagnet assembly to attract and separate the firing carrier 8. At this time, continuing to push the bolt 42 will place the ammunition in front of the firing carrier 8. Finally, releasing the hand (or reducing or stopping the force applied to the bolt 42) will push the bolt 42 back through the return spring in the spring groove. Under the combined action of the return spring and the positioning spring, the bolt 42 is fully reset, thereby blocking the magazine and preventing it from continuing to be filled with ammunition. This completes one round of reloading and loading. The bolt mechanism 4 is mainly used for loading ammunition and pushing the ammunition to the front of the firing carrier 8. The specific positions and structures of the positioning spring and the return spring of the bolt mechanism 4 are not specifically limited in this application embodiment. They can be designed according to the actual situation. The main purpose is to realize its functions of loading and pushing ammunition.

[0041] Furthermore, the magazine assembly 5 includes a magnetic adsorption plate 51, a multi-functional magazine 52, and an automatic magazine changer 53. The multi-functional magazine 52 is connected to the magnetic adsorption plate 51 and is attached to the connecting body 41 of the bolt mechanism 4 via the magnetic adsorption plate 51. The automatic magazine changer 53 is fastened below the multi-functional magazine 52, and a spring ejects the ammunition inside the multi-functional magazine 52 into the firing tube. The magazine assembly 5 is magnetically attached to the lower part of the bolt mechanism 42. When reloading is required, the spring in the automatic magazine changer 53 ejects the ammunition from the multi-functional magazine into the firing tube above. Ammunition can be selected according to the actual situation, including large projectiles such as ping-pong balls and capture nets, as well as small projectiles such as tranquilizer darts and water bullets.

[0042] Furthermore, the rail power supply unit 6 is fully fitted onto the firing tube, with its front end connected to the rear end of the rail body 7 via a connecting post 9. Both the connecting post 9 and the rail power supply unit 6 have wire holes 10 on both sides. The rail power supply unit 6 is mainly used to provide driving current to the rail circuit 71 of the rail body 7. The outgoing wires pass through the wire holes 10 and connect to the rail body 7. In addition, it can also serve as a backup power source. Depending on the actual situation, it can be selected to cooperate with the bolt mechanism 4, connecting to the bolt mechanism 4 via a return spring in the spring groove to jointly achieve the loading function.

[0043] Furthermore, such as Figure 5 As shown, the electromagnet assembly is disposed between the connecting post 9 and the guide rail body 7, including a loading electromagnet 74 and a trigger switch 75. The trigger switch 75 is disposed within the wire hole 10 of the connecting post 9 and connected to the guide rail power supply 6 via a spring and wire. The loading electromagnet 74 is disposed within the mounting hole at the rear end of the guide rail body 7 and is controlled by the trigger switch 75. In this embodiment, the electromagnet assembly is preferably disposed between the connecting post 9 and the guide rail body 7. The magnetism of the loading electromagnet 74 is controlled by pressing the trigger switch 75, thereby controlling the separation and closure of the firing carrier 8. During loading, when the bolt 42 is pulled forward, the trigger switch 75 is pressed. At this time, the loading electromagnet 74 becomes magnetic and attracts the firing carrier 8, separating its upper and lower parts. The ammunition passes between the firing carriers 8 and stops in front of them. After releasing the bolt 42, the trigger switch 75 is no longer pressed, the loading electromagnet 74 loses its magnetism and no longer attracts the firing carrier 8, and the upper and lower parts of the firing carrier 8 close.

[0044] Furthermore, the launch carrier 8 is cross-shaped, allowing for the separation of its upper and lower parts under the attraction of the loading electromagnet 74. The launch carrier 8 can be selected according to actual needs, and during the loading process, it can also be separated and closed by left-right attraction. The main purpose is to ensure the ammunition is positioned before the launch carrier 8, allowing it to continue firing the next ammunition when returning to its initial position, preventing it from getting stuck in front of the ammunition and malfunctioning the equipment. In fact, any loading method that ensures the ammunition is in front of the launch carrier 8 just before firing is acceptable. For example, the loading time can be controlled, allowing precise loading when the launch carrier 8 returns to its initial position, at which point the ammunition's loading position can be adjusted to be within the firing trajectory. Moreover, the loading electromagnet 74's function is simply to open the launch carrier 8 to allow the ammunition to reach the preset firing position. In reality, the loading electromagnet 74 can be replaced with a traction spring, traction rod, or any other material or structure capable of performing this function.

[0045] Furthermore, such as Figure 7As shown, the guide rail circuit 71 is a magnetizing circuit composed of multiple rows of connected "I"-shaped iron cores. In this embodiment, the guide rail circuit 71 consists of four rows of magnetizing circuits connected by "I"-shaped iron cores, with a maximum of 60 independent magnetizing circuits per row, for a total of 240 independent magnetizing circuits. The magnetizing circuits are preferably placed side-by-side to save space on the launch track. Depending on the actual situation, a staggered arrangement can also be used to fully utilize the magnetic field generated by each circuit.

[0046] More specifically, the principle of the ammunition exit velocity control in the embodiments of this application will be briefly explained with reference to the corresponding circuit diagrams. As shown in Figure 8, the current providing the magnetic field is the magnetic supply circuit. As shown in Figure 9, the circuit diagram providing the current to the magnetic supply circuit is the capacitor charging process. The two circuits together constitute... Figure 10 The magnetizing circuit, consisting of several magnetizing circuits, forms a magnetizing system that provides a controllable magnetic field B to the launch carrier 8, powered by power supply U. e Directly providing drive current I0 to the launch carrier 8, by Figure 10 It can be seen that the expression for the driving current through the emitter is:

[0047]

[0048] The induced electromotive force generated by the launch carrier 8 cutting the magnetic field can be written as:

[0049]

[0050] The total current (effective driving current) can be expressed as the original current passing through the emitter minus the induced current generated by the emitter cutting the magnetic field, i.e.:

[0051]

[0052] According to Newton's second law, for the projectile:

[0053]

[0054] Substituting equation (2) into equation (3) and integrating, we obtain the velocity of the launcher as:

[0055]

[0056] Assuming the launcher reaches the launch port at time t0, integrating the velocity and setting it equal to the known displacement distance, we can obtain the following condition at t0:

[0057]

[0058] Substituting the solved t0 into equation (4), we can obtain the expression for the muzzle kinetic energy of the projectile:

[0059]

[0060] The above formula can be used to determine various parameters that affect the muzzle kinetic energy of the ammunition. Depending on the actual situation, the corresponding parameters can be changed to control the muzzle velocity of the projectile.

[0061] Furthermore, such as Figure 6 As shown, the electromagnetic shielding layer 72 has a multi-layer structure, consisting of a magnetic field shielding layer, a ceramic insulating layer, a hydraulic ring, a substrate layer, and a hydrophobic coating from the inside out. The electromagnetic shielding layer 72 primarily serves to shield against external interference and provide protection. The outermost hydrophobic coating, which can be made of fluorocarbon paint, silicone, or similar coatings, increases the contact angle between the outer surface and water droplets, making it less likely for water droplets to remain on the outer surface and significantly reducing the probability of water droplets penetrating the composite matrix. The substrate layer can be a composite material made of A-151 and Woland-treated glass fiber, primarily serving to prevent moisture and heat damage while maintaining good conductivity. The hydraulic ring is designed to prevent material deformation caused by thermal stress from damaging the internal structure of the shielding layer, thus reducing its performance or even causing it to be destroyed. Its main purpose is to reduce stress on the substrate layer. The hydraulic ring is selected based on the actual situation, taking into account the influence of the structure. If the mass of the accelerated launch carrier 8 is small, the exit velocity is low, and the required driving magnetic field is small, the stress generated is relatively small, and there is no need to set up a hydraulic ring. Conversely, a hydraulic ring is required; otherwise, the electromagnetic shielding layer 72 will deform or even break and cannot work properly. The ceramic insulating layer and the magnetic field shielding layer are mainly to ensure that the external magnetic field does not interfere with the magnetic field inside the guide rail, and also to ensure that the magnetic field inside the guide rail does not cause harm to external equipment or human beings. They mainly serve to block the internal and external magnetic fields. The materials used to make the magnetic field shielding layer can be metals such as iron, nickel, chromium, and cobalt, as well as their compounds.

[0062] Furthermore, both the main power supply library 1 and the rail power supply library 6 are powered by batteries. The main power supply library 1 is mainly used to power all modules of the electromagnetic gun, while the rail power supply library 6 is mainly used to power the rail body 7 and as a backup power supply. The configuration depends on the actual situation. If only short-term power supply is required and the launch mission requirements are not high, the rail power supply library 6 can be omitted, and the main power supply library 1 can be used directly. If long-term power supply or fixed-position use is required, the main power supply library 1 can be replaced with a 220V AC mains power supply; in this case, only the corresponding voltage and current control circuit needs to be added.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
