Description

Technical Field

[0001] The present application relates to the field of gunpowder-fueled MHD power generation, and in particular to a gunpowder-fueled generator. Background Art

[0002] When gunpowder is used as the energy source for the shooting process of guns and cannons, extremely complex physical and chemical reactions will occur in the limited space inside the chamber, manifested as gunpowder combustion, gas generation, state changes, energy conversion and projectile movement, and these phenomena interact and even overlap with each other, which is extremely difficult for the research on MHD (Megnetohydrodynamics) generator mechanism developed by using gunpowder combustion energy. This is because the combustion of gunpowder in the chamber continuously produces high-temperature gas, reaching 4000℃. The increase in gas volume will inevitably lead to an increase in the pressure inside the chamber. Generally, the pressure of a cannon is 3000㎏ / cm 2 , which drives the projectile to accelerate. For example, the muzzle velocity of an armor-piercing projectile can reach more than 1000m / s, that is, part of the internal energy of the gunpowder gas is converted into the kinetic energy of the projectile and other forms of energy. In essence, it is an energy conversion process that changes mass and volume.

[0003] During the firing process of conventional ammunition, a large amount of gunpowder combustion energy is consumed when firing the projectile, but the heat loss potential after the gunpowder burns cannot be utilized as a resource, resulting in a large amount of gunpowder combustion energy wasted, the gunpowder combustion energy utilization rate is low, and even affects the ecological environment. Summary of the invention

[0004] The purpose of the present application is to provide a gunpowder combustion power generator to solve the problem of low utilization rate of gunpowder combustion energy when launching projectiles.

[0005] To achieve the above objectives, this application provides the following solutions:

[0006] In a first aspect, the present application provides a gunpowder combustion power generator, comprising:

[0007] The barrel and power generation channel;

[0008] The barrel is arranged at the entrance of the power generation channel, and gunpowder gas plasma and metal projectiles are built in the barrel; the gunpowder gas plasma is the heat loss of gunpowder combustion energy and the heat loss potential that cannot be used when the gunpowder is fired;

[0009] The power generation channel is made of high-T material, and electrodes are provided on the side walls of the power generation channel;

[0010] The metal projectile and the plasma are driven to enter the magnetic field of the power generation channel in sequence, and the magnetic lines of force of the magnetic field are cut, and pulse electric energy is generated on the electrodes, thereby forming a metal direct magnetic pulse generator and a plasma MHD generator.

[0011] According to the specific embodiments provided by the present application, the present application discloses the following technical effects: the present application provides a gunpowder combustion energy generator, which utilizes a portion of the gunpowder combustion energy to sequentially drive the metal projectile and the gunpowder gas plasma in the barrel to a power generation channel made of high-T material. The gunpowder gas plasma is the heat loss of the gunpowder combustion energy and the heat loss potential that cannot be utilized when the gunpowder is fired. Since the power generation channel is a magnetic channel of high-T material, when the metal projectile enters the magnetic field of the power generation channel, the metal projectile cuts the magnetic lines of force to generate pulse electric energy, forming a metal direct magnetic pulse generator, and the gunpowder gas plasma generated by the remaining gunpowder combustion energy also enters the magnetic field of the power generation channel to cut the magnetic lines of force to generate pulse electric energy, forming a plasma MHD generator, so that the heat loss potential that cannot be utilized when the gunpowder is fired can also be utilized as a resource. The present application has created a new principle of high-power pulse generator of metal + plasma MHD, and improved the utilization rate of gunpowder combustion energy.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1 As shown, an embodiment of the present application provides a gunpowder combustion energy generator, including: a barrel 3 and a power generation channel 8; the barrel 3 is arranged at the entrance of the power generation channel 8, and the barrel 3 contains gunpowder gas plasma 4 and metal projectile 5; the gunpowder gas plasma 4 is the heat loss of gunpowder combustion energy and the heat loss potential that cannot be utilized when the gunpowder is fired; the power generation channel 8 is made of high-T material, and an electrode 6 is arranged on the side wall of the power generation channel 8; the metal projectile 5 and the plasma are driven to enter the magnetic field of the power generation channel 8 in turn, cutting the magnetic lines of force of the magnetic field, and pulse electric energy is generated on the electrode 6, forming a metal direct magnetic pulse generator and a plasma MHD generator.

[0025] In an exemplary embodiment, the outer wall of the power generation channel 8 is wrapped with an insulating wall.

[0026] In an exemplary embodiment, the electrode 6 is a contact electrode.

[0027] In an exemplary embodiment, the metal shot 5 does not contain explosives.

[0028] In an exemplary embodiment, the present application further includes: a cartridge 2; the cartridge 2 is arranged at the entrance of the barrel 3; the cartridge 2 contains gunpowder 1.

[0029] In an exemplary embodiment, the present application further includes: a load 9 ; the load 9 is connected to the electrode 6 .

[0030] If the metal projectile 5 and plasma moving at high speed in the chamber are used as MHD power generation medium, when they move at high speed in the chamber, they will simultaneously pass through the power generation channel 8 designed by the magnet 7 at the mouth of the chamber, cutting the magnetic lines of force, and will inevitably generate induced potential synchronously, so it is defined as gunpowder combustion MHD technology.

[0031] Its scientific basis is derived from the mechanism of liquid metal magnetohydrodynamic (LMMHD) power generation and the mechanism and structure of gunpowder combustion to accelerate projectiles. For the emerging LMMHD technology, a heat source must be used to liquefy metal to become a power generation medium, and a high-speed drive device is required to make it move at high speed and cut the magnetic lines of force. The present application uses gunpowder combustion in the barrel 3 of a typical gun or cannon to drive the metal projectile 5 and plasma at high speed. If the silencer or recoil brake at the muzzle is designed with high-T material to be a magnet channel that can also be used for power generation, the main body of the gunpowder combustion MHD generator can be formed. The main structure of the generator is as follows: Figure 2 shown.

[0032] The main components of the gunpowder combustion generator provided in this application include propellant 1, metal projectiles 5 without explosives, barrel 3, power generation channel 8 as muzzle magnet de-energizer or silencer, gunpowder gas and plasma, electrodes 6, etc. Among them, the structures and positions of the propellant 1, projectiles, barrel 3, etc. are as follows: Figure 1 As shown, its structure can be standard or universal, but the projectile should be free of explosives.

[0033] In addition, in order to improve the power generation performance, the propellant 1 can be added with ionized seeds and other specially designed formulas or customized. As for the main body of the generator, it is a power generation channel 8 composed of a magnetic de-energizer or a muffler, and a contact electrode 6 designed on its inner wall, which constitutes the main body of the generator. The specific structural model is as follows Figure 3 shown.

[0034] The workflow is as follows: During the process of firing a projectile from a gun or cannon, Figure 4As shown, the firing pin fires the primer, ignites the propellant 1 in the cartridge 2, and can generate high-temperature, high-pressure propellant gas and high-temperature ionized plasma in the barrel 3, driving the metal projectile 5 and plasma to move toward the muzzle at high speed. When the muzzle brake or silencer is designed as a high-T magnet, the metal projectile 5 and plasma pass through the magnetic field of the power generation channel 8 at high speed, which will inevitably generate an electromotive force on the electrode 6 in the power generation channel 8. And when the power generation structure such as the power generation channel 8 with different parameters such as length is adopted, a high-power pulse power supply with a current of tens of KA and a peak power of hundreds of KW-MW level will be generated on the load 9 of the electrode 6.

[0035] Therefore, the principle of MHD technology can be explained by Figure 5 As shown in the figure, its main body is derived from guns, cannons, rockets and other launching devices. In the process of shooting projectiles, training, etc., this high-power pulse source can be constructed simultaneously, and then after shaping and other processing, it can be used as a power source for launching high-energy weapons such as lasers. Multifunctional new concept weapons can be developed, which can launch conventional projectiles and lasers, electromagnetic shells, etc. at the same time.

[0036] It can be seen that this power generation technology not only effectively utilizes gunpowder energy to drive the kinetic energy of projectiles to generate electrical energy (especially suitable for automatic weapons such as machine guns), but also effectively solves the problem of high-power pulse power supply for high-energy weapons.

[0037] What is more significant is that, during the process of launching a projectile, only 32% of the gunpowder energy can be used for MHD power generation when it is converted into the kinetic energy of the projectile, and about 60% of the gunpowder energy is converted into heat energy or cannot be used, which is wasted and even causes damage to the weapon and the environment, as shown in Table 1.

[0038] Table 1 Energy utilization rate of gunpowder for a medium-caliber artillery

[0039]

[0040]

[0041] In the gunpowder combustion MHD technology of the present application, 32% of the gunpowder combustion energy is first used to generate kinetic energy for the projectile, and then the high-speed projectile is simultaneously used for MHD power generation to generate electricity; then the 60% of the heat loss of the gunpowder combustion energy and its unused potential are resourced as much as possible to become high-temperature plasma, and then continuously used for MHD power generation. The research on this gunpowder combustion MHD power generation technology will be more meaningful.

[0042] In fact, the unused heat loss potential of propellant 1 and other propellant gases can be ionized at high pressure and high temperature to produce high-speed plasma. Figure 3The advanced explosive plasma MHD power generation principle uses the gunpowder gas plasma 4 as the conductive fluid MHD fusion design in the combustion MHD generator. That is, after the metal projectile 5 cuts the magnetic field of the muzzle or muzzle magnet recoiler to generate electricity, the high-speed plasma also cuts the muzzle magnetic field to continuously generate electricity.

[0043] As for how much of the heat loss potential of gunpowder 1 can be used as a resource, it is still under study. Even if a small amount of the heat loss potential of gunpowder can be used as a resource, using it to develop this gunpowder combustion energy MHD power generation technology will also be a huge leap in the reuse of gunpowder combustion energy. The efficiency of gunpowder heat loss potential utilization can be improved by changing the type and shape of the charge and adding ionized seeds.

[0044] The present application includes two power generation systems. One is a direct magnetic pulse generator that studies the launch of gunpowder energy to drive metal projectiles 5. The other is a gunpowder gas plasma MHD generator that launches gunpowder energy and can be ionized at high temperature. Both occur simultaneously in the link of using gunpowder energy to launch projectiles, so it is temporarily defined as gunpowder energy MHD power generation technology. The metal projectiles 5 involved in this application are all projectiles without explosives, such as a large number of gun bullets, armor-piercing bullets fired by artillery, training sand bullets, etc.

[0045] This application intends to use the silencer or recoil brake of a certain standard gun or cannon, the barrel 3, the metal projectile 5 without explosives, etc. as the research carrier, and explain the technology and method of generating the MHD high-power pulse power supply from three aspects: theoretical analysis and calculation, numerical simulation and principle test verification, such as Figure 6 As shown, the generator structure provided by the present application may seem simple, but the entire power generation process is carried out in an extremely complex environment of high pressure, high temperature, high speed and other extreme power generation channels 8 driven by the combustion energy of propellant. The complexity and research difficulties are mainly reflected in:

[0046] Step 1: Theoretical analysis and solution of MHD power generation by gunpowder combustion: First, based on the ammunition launching process and MHD principle, the firing state of typical guns and cannons is simulated through AUTODYN simulation and the design of the firing gunpowder 1 charge. From the perspective of resource utilization of the firing gunpowder energy, the various high-temperature and high-pressure flow fields and plasma states in the chamber and muzzle when the gunpowder 1 is burning are simulated based on the unsteady aftereffect theory combined with multi-field coupled finite element numerical simulation. The high-speed metal projectile 5 and plasma are developed as MHD power generation working fluids, and the power generation channel 8 structural models with different shapes and materials, i.e., the main structure of the generator, are designed and generated based on this simulation data.

[0047] Moreover, since the power generation medium of the gunpowder fuel MHD is different from the single-phase liquid metal power generation medium of the MHD, it is formed by the metal projectile 5 and plasma driven by the combustion energy of the propellant 1, and its parameter characteristics such as speed, conductivity and electron density vary with the material, shape and ionization seed of the cartridge 2, and are affected by the ablation and flow field of the high-temperature and high-pressure gunpowder gas, all of which affect the research on the power generation performance. Therefore, it is necessary to combine numerical simulations such as multi-field coupling and decoupling for comprehensive research.

[0048] Step 2, numerical simulation of power generation channel 8, development of special high-power pulse power supply: Based on the power generation channel 8 structural model established in step 1, consider that the gunpowder-fueled MHD power generation channel 8 is a fusion of multiple dynamics and multi-field couplings, including shock wave power generated by the combustion of gunpowder 1, gunpowder gas power, plasma fluid power, magnetohydrodynamic power, etc. Therefore, the power generation channel 8 has multiple field couplings such as temperature field, pressure field, velocity field, electric field and magnetic field. At present, there is no analysis and calculation of various field distributions, and further development and research is needed. To this end, this application uses the incompressible fluid Navier-Stokes equations and the secondary development Fluent MHD module to realize 3D numerical simulation of the multi-field coupling inside the gunpowder-fueled generator, laying a scientific basis for the development of special high-power pulse power supplies.

[0049] Step 3, Principle Test Verification and Power Generation Performance Simulation of Gunpowder-fueled MHD Power Generation: Although the main body of the gunpowder-fueled MHD generator can be constructed theoretically by step 2, from the perspective of the formation and acquisition of the power generation medium of the gunpowder-fueled MHD, it is impossible to obtain high-speed metal projectiles 5 or gunpowder gas plasma 4 in the laboratory. In particular, gunpowder 1 combustion plasma is different from nuclear fusion plasma, and has the characteristics of high pressure, transient state and low ionization degree, which brings great difficulties to the principle test verification of power generation. Moreover, for the design of the magnet 7, electrode 6, etc. of the power generation channel 8, it is also necessary to comprehensively and collaboratively consider the applicability of the silencer or muzzle brake on the barrel 3, which brings difficulties to the design of small volume, high strength and light weight.

[0050] To this end, this application comprehensively considers the aerodynamic characteristics and safety of the generator body, coordinates the design of silencers or recoil brakes of guns and cannons using high-T materials and corresponding structures, designs the gunpowder 1 charge type, formula, structure, etc. to coordinate with the generator, constructs a gunpowder-fueled MHD power generation system and model principle prototype, combines MHD model simulation with ultra-high power-to-weight ratio pulse technology, carries out principle simulation experimental verification research, and develops a high-power pulse power supply simulation principle prototype suitable for powering high-energy weapons.

[0051] This application intends to comprehensively consider the resource utilization of the energy of the combustion of gunpowder 1 for MHD power generation. From the microscopic perspective of the projectile launching process, the microstructures of the launching gunpowder 1 charge microelement, the projectile microelement, the barrel 3 microelement, the power generation channel 8 microelement of the magnetic silencer or muzzle brake, the plasma, and the related various flow fields and interacting coupling fields are comprehensively studied. It is expected to utilize 1 / 3 of the energy of the gunpowder combustion to launch the projectile, and then use it for MHD power generation simultaneously. At the same time, nearly 2 / 3 of the unutilized potential or thermal energy of the gunpowder is utilized as much as possible for plasma MHD power generation.

[0052] The above two power generation systems are specifically formed as follows:

[0053] According to the process of gunpowder combustion to launch the projectile, the gunpowder 1 burns to produce a large amount of high-temperature, high-pressure and even high-temperature ionized gunpowder gas, which drives the projectile and plasma to enter the redesigned muzzle magnet 7 silencer or muzzle brake power generation channel 8 at high speed. When the metal projectile 5 cuts the magnetic lines in the power generation channel 8, it will generate pulse electric energy to form a metal direct magnetic pulse generator; then, the plasma will also cut the muzzle magnetic lines and generate pulse electric energy to form a plasma MHD generator.

[0054] In fact, if the external magnetic field B0 is in the y direction and the movement is in the z direction, if the conductive metal projectile 5 and the plasma are passed into the power generation channel 8 at a high speed v and the movement direction is perpendicular to the magnetic field direction, then an induced potential can be obtained in the direction perpendicular to the movement direction and the magnetic field direction. Electrodes 6 are installed on the two side walls of the power generation channel 8, and an external load 9 is connected. The resistance of the load 9 is R L , current will be generated in the circuit.

[0055] Without considering the induced magnetic field, according to Faraday's law of electromagnetic induction, when the metal projectile 5 passes through the magnetic field, there will be a steady-state electromagnetic output power of:

[0056]

[0057] Among them, R g is the internal resistance of the generator, and a is the diameter of the power generation channel 8.

[0058] It can be seen that under the condition that the generator's external dimensions are relatively fixed, in order to obtain useful output power, it is necessary to have a smaller internal resistance, a higher speed generating fluid, and a higher magnetic induction intensity.

[0059] Generally, the metal pellets 5 have a high electrical conductivity (10 6 level), and the speed is hundreds or even thousands of meters per second, so its magnetic Reynolds number R m =σμ0vw is greater than 1, and the influence of the induced magnetic field on the original magnetic field cannot be ignored. Therefore, considering the high magnetic Reynolds number, the electric power on the load 9 is:

[0060]

[0061] Among them, σ and μ0 are the electrical conductivity and magnetic permeability of the power generation medium respectively; d is the equivalent electrode spacing; w is the equivalent width of the power generation channel 8.

[0062] When the load 9 resistance is R L , and ignoring the line and electrode 6 resistance, the resistance of the projectile can be defined as the internal resistance of the pulse generator, then its equivalent circuit is as follows Figure 7 shown.

[0063] Therefore, when the length of the power generation channel 8 of the projectile along the moving direction is l, the internal resistance of the pulse generator is:

[0064]

[0065] The current and voltage on load 9 are:

[0066]

[0067] The total power generation is:

[0068]

[0069] The power generation efficiency is the ratio of the output power to the chemical energy E of the gunpowder:

[0070]

[0071] Therefore, when the projectile is driven directly by the propellant 1 gas to flow in the power generation channel 8 at a high speed, an electromotive force will be induced. According to preliminary estimates, when the conductivity of the projectile is 5.7×10 7 S / m, speed is about 800m / s, the spacing between electrodes 6 is 8mm, the length of electrode 6 is 20mm, the external magnetic field is 1T, and an output power of 32kW can be generated, the voltage is 4V, the current is 8kA, and the pulse is 25μs. The power generation of plasma MHD can also be estimated.

[0072] In particular, the gunpowder-fueled MHD power generation channel 8 proposed in the present application is formed by the combustion of the propellant gunpowder 1. It is a multi-power, multi-field coupled channel composed of high-temperature, high-pressure gunpowder gas, plasma, high-speed metal projectiles 5, high-T magnets 7, etc. The power generation environment is extremely complex. Therefore, it is necessary to carry out research on gunpowder-fueled MHD power generation working fluids and related magnetohydrodynamics.

[0073] For a long time, people have only paid attention to the speed and range of projectile launch, and rarely studied the motion and electromagnetic characteristics of projectiles and the plasma burning in the chamber. In particular, the resource utilization of gunpowder energy, using the fired projectiles and the generated plasma as power generation medium, has not been studied yet. Therefore, if they are used for gunpowder combustion MHD power generation, it is necessary to study not only their motion and speed characteristics, but also their resistivity, conductivity, electron density and other electromagnetic characteristics that affect power generation performance.

[0074] For metal projectiles 5, there are currently a large number of studies available for reference, which often focus on projectile structure, power and aerodynamic characteristics, and have not yet been used as power generation working fluid research. In this application, the projectile being fired, as a pure metal material, has good conductivity, high-speed movement and good contact with the inner wall of the chamber. The high-temperature and high-pressure gunpowder gas energy generated by the combustion of the firing gunpowder 1, of which about 32% of the energy is given to the projectile at a high speed, lays the foundation for the gunpowder combustion energy MHD power generation technology.

[0075] This application has the following advantages:

[0076] 1. The first MHD power generation technology using propellant fuel.

[0077] It is expected that by focusing on the huge energy-containing propellant for the first time and combining it with advanced MHD technology, we can create the first high-power pulse special new energy technology of gunpowder-fired MHD, from building new concepts, new principles, new methods to new power generation systems for fuel MHD, and explore a new way to develop new energy technologies and gunpowder-fired MHD power generation technology;

[0078] 2. The first new principle of gunpowder fuel magnetohydrodynamic power generation was created to improve the utilization rate of propellant fuel energy.

[0079] Directly targeting the resource utilization of propellant energy, it is proposed that in the process of firing conventional ammunition, the propellant combustion energy consumed in large quantities when firing the projectile, in addition to the usual radial motion of the metal projectile 5 and plasma driven at high speed in the bore, can be synchronously passed through the magnetic field of the specially designed power generation channel 8 at the muzzle to generate an electromotive force, thus creating a new principle of high-power pulse generator of metal + plasma MHD and improving the utilization rate of propellant combustion energy.

[0080] 3. The new method of MHD power generation using gunpowder combustion can effectively solve technical bottlenecks such as mobility and continuous launch.

[0081] For the first time, a gunpowder combustion MHD system is constructed using metal projectiles 5 and plasma as power generation fluids and a magnetic de-energizer as a power generation channel 8 carrier. Then, magnetohydrodynamic analysis and control of the flow field of the power generation channel 8 under high magnetic Reynolds number are used to create a high-power pulse power supply. This system combines the characteristics of the ammunition carrier, such as huge energy content and maneuverability, with the advantages of advanced explosive plasma MHD technology, and has obvious advantages in terms of light weight, mobility, and continuous firing.

[0082] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
