Abstract
Description
Technical Field
[0001] This invention relates to the field of electromagnetic launch technology, and in particular to a self-powered launcher structure for electromagnetic reconnection gun launch. Background Technology
[0002] Human societal development has progressed through three stages: mechanical energy emission, chemical energy emission, and electromagnetic energy emission. The extremely high speed and long range of the launch vehicle have always been important areas of scientific and technological research. Electromagnetic emission refers to the emission of electromagnetic energy, directly converting electromagnetic energy into the kinetic energy of the launch vehicle. With its advantages of being clean, highly efficient, sustainable, pollution-free, ultra-high-speed, low-noise, highly controllable, and not limited by the speed of sound, it has broad application prospects in many fields such as aerospace, transportation, scientific research, and national defense. Countries around the world are vying to conduct applied research on electromagnetic emission technology.
[0003] The re-launch method, also known as the re-launch, utilizes electromagnetic induction to generate eddy currents within the metal launcher. These eddy currents, combined with the magnetic field of a hollow coil, create an electromagnetic force that accelerates the launcher. Its key features include strong pulse excitation, strong electromagnetic coupling, and high launch kinetic energy. Compared to orbital launch, re-launch offers advantages such as frictionless operation, no ablation, and the ability to launch large payloads. Compared to coil launch, it boasts high thrust and high efficiency, making it the most valuable launch mode for research.
[0004] However, existing reconnection guns typically use solid metal plates or coiled launchers. The former is prone to uneven eddy current distribution, resulting in weak current-carrying capacity of the launcher, which in turn leads to low peak electromagnetic thrust and launch velocity. The latter enhances the current-carrying capacity of the launcher and improves the peak electromagnetic thrust and launch velocity, but the launch efficiency is still low and the launch range is still limited. Therefore, we propose a self-powered launcher structure for electromagnetic reconnection guns.
[0005] Therefore, this application provides a self-powered launcher structure for electromagnetic reconnection gun firing to meet the requirements. Summary of the Invention
[0006] The purpose of this application is to provide a self-powered launcher structure for electromagnetic reconnection gun firing.

The battery module is used to provide power to the transmitter and to achieve self-protection management. The rectifier circuit module is used to rectify the DC current output by the battery module into high-voltage DC current. The energy storage and transmitting circuit module includes an energy storage capacitor, a transmitting coil, and an electromagnetic transmitting module. The high-voltage DC power output from the rectifier circuit module charges the energy storage capacitor via the high-voltage DC module. The energy storage capacitor discharges to supply power to the transmitting coil. The transmitting coil generates a magnetic field to accelerate the transmitter. The high-voltage DC voltage limiting circuit module controls the battery module to stop supplying power when it detects that the voltage of the energy storage capacitor has reached a set value.

The metal shell is provided with a groove structure and a boss structure, and the modules are fixed by a connecting structure. The shape of the metal casing can be any one of the following: circular, rhomboid, triangular, square, or irregular.
[0010] Preferably, the integrated circuit module achieves physical connection and signal communication between each module through connecting structural components, enabling the transmission of various control signals and adjustment of working state according to preset commands, forming a compact and controllable integrated module structure.
[0011] Preferably, the switch in the high-voltage DC voltage limiting circuit module that controls the battery module to stop supplying power is any one of a capacitive switch, a Hall effect switch, or a photoelectric switch.
[0012] Preferably, the control module controls the rectifier circuit module to trigger the battery module and the energy storage transmitter circuit module to start working through the detection signal transmitted by the acquisition module; When the acquisition module detects that the transmitter has reached the preset transmission endpoint, or when the voltage of the energy storage capacitor has reached a set value, the control module sends a stop power supply command to the battery module.
[0013] In summary, the technical effects and advantages of this invention are as follows: This invention can better achieve controllable high firing rate, high firing efficiency, ultra-long range and continuous firing, and has a simpler and more compact structure and better safety.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example: Reference Figure 1-3 The diagram shows a self-powered launcher structure for launching electromagnetic reconnection guns. The core carrier of this launcher structure is a metal outer shell 8, the shape of which can be circular, such as... Figure 1 As shown, the inner wall of the outer casing is provided with a groove structure 11 and a boss structure 12, and the various functional modules are fixed and connected through the connecting structure 13: Battery module 1 is fixed to boss structure 12 via connecting structure 13; Energy storage and transmission circuit module 3 is embedded in groove structure 11; The metal outer shell 8 is divided into several areas, including Space 1 1001, Space 2 1002, Space 3 1003, and Space 4 1004, which can be selectively filled with explosives, spare circuit components, and other auxiliary parts.
[0019] The metal casing 8 encapsulates an integrated circuit module 9, which integrates a battery module 1, a rectifier circuit module 2, a high-voltage DC module 4, an energy storage and transmission circuit module 3, a high-voltage DC voltage limiting circuit module 5, an acquisition module 6, and a control module 7. The modules are physically connected and communicate with each other through the connecting structure 13.
[0020] As one implementation method in this embodiment, battery module 1 uses a high-rate lithium battery as the power supply core and is equipped with a BMS (Battery Management System), a thermal management system and a connecting structure 13. The thermal management system monitors the cell voltage, operating temperature and total current of the lithium battery in real time. The BMS realizes the charge balance and overcharge / over-discharge protection of the battery. The connecting structure 13 is used to establish electrical connections with other modules.
[0021] As one implementation method in this embodiment, the rectifier circuit module 2 adopts a full-bridge rectifier circuit, with its input terminal electrically connected to the output terminal of the battery module 1, and is used to convert the low-voltage DC current output by the battery module 1 into high-voltage DC current.
[0022] As one implementation method in this embodiment, the energy storage and transmitting circuit module 3 includes a high-voltage energy storage capacitor 301, a multi-turn transmitting coil 302, and an electromagnetic transmitting module 303; the input terminal of the energy storage capacitor 301 is connected to the output terminal of the high-voltage DC module 4, and the output terminal is connected in series with the transmitting coil 302, which is wound around the outer periphery of the electromagnetic transmitting module 303.
[0023] As one implementation method in this embodiment, the high-voltage DC voltage limiting circuit module 5 uses a Hall effect switch as the control element. Its detection terminal is connected in parallel with the energy storage capacitor 301, and its control terminal is connected in series with the power supply circuit of the battery module 1.
[0024] As one implementation method in this embodiment, the acquisition module 6 integrates a voltage sensor to monitor the voltage of the energy storage capacitor 301 and a position sensor to monitor the flight status of the transmitter 14, and its output terminal is connected to the signal input terminal of the control module 7.
[0025] As one implementation method in this embodiment, the control module 7 uses a microcontroller as the core controller, and its signal output terminal is electrically connected to the control terminals of the rectifier circuit module 2 and the battery module 1 respectively, so as to realize the working trigger and state switching of each module.
[0026] Working principle of the invention: Launch preparation stage: After the launcher 14 is installed into the electromagnetic reconnection gun launcher, the BMS of the battery module 1 starts self-test, the thermal management system monitors the battery status and transmits the data to the control module 7; the control module 7 completes initialization through the acquisition module 6 and confirms that each module is in a ready-to-work state.
[0027] During the energy storage charging stage: the control module 7 sends a trigger signal to the rectifier circuit module 2, which rectifies the low-voltage DC output from the battery module 1 into high-voltage DC, which is then charged to the energy storage capacitor 301 of the energy storage transmitting circuit module 3 via the high-voltage DC module 4. At the same time, the high-voltage DC voltage limiting circuit module 5 monitors the voltage of the energy storage capacitor 301 in real time. When the voltage reaches the preset threshold, its Hall effect switch disconnects the power supply circuit of the battery module 1 and stops charging.
[0028] Electromagnetic acceleration phase: After the launching device triggers the launch command, the control module 7 receives the start signal from the acquisition module 6, and then controls the energy storage capacitor 301 to discharge to the launching coil 302; after the launching coil 302 is energized, it generates a strong magnetic field such as Figure 3 As shown, the magnetic field lines are axially symmetrically distributed and couple with the external magnetic field of the re-launcher. Eddy currents are generated in the launcher 14 through electromagnetic induction. The interaction between the eddy currents and the magnetic field forms electromagnetic thrust, which propels the launcher 14 to move at high speed.
[0029] State control phase: During the flight of the launcher 14, the acquisition module 6 monitors its flight position and the remaining voltage of the energy storage capacitor 301 in real time; when the launcher 14 is detected to have reached the preset launch endpoint, or when the voltage of the energy storage capacitor 301 drops below the threshold, the control module 7 sends a stop command to the battery module 1 to terminate the power supply; after the launcher 14 is separated from the launch device, it can fly stably by relying on the aerodynamic shape of the metal shell 8. If the internal space is filled with explosives, it can be detonated in a subsequent stage.
