Description

Technical Field

[0001] The present invention relates to the technical field of impact compression loading, and in particular to a device and method for improving energy transfer of a light gas gun. Background Art

[0002] Dynamic high pressure technology is widely used in scientific research, and light gas guns are the most widely used scientific means, especially in the study of meteorite collision, state equation, dynamic mechanical properties of materials and explosive explosion.

[0003] The two-stage light gas gun is a special controllable high-speed launch device, usually composed of a gunpowder chamber, a pump tube, a high-pressure section, a launch tube and a target chamber. This gas gun uses the gun as a compression stage to push the piston, dynamically compressing the light gas in the pump tube, which can make its pressure reach hundreds of megapascals. Therefore, it is possible to accelerate the flying pieces to extremely high speeds. Thus, through the collision between the projectile and the target body, an impact pressure ranging from 100,000 atmospheres to 5 million atmospheres can be generated, and a high temperature state of hundreds of thousands of degrees Celsius can be reached. This state under high pressure conditions can be used to study the state equation of materials under high pressure, impact phase transition and melting, electromagnetic properties of materials, impact synthesis of new materials, and high-speed collision phenomena.

[0004] In the experiment, the high-pressure section is an important part of the light gas gun. The storage and release of the high-pressure section gas determines the speed of the projectile, thus affecting the overall experimental effect. In the stage of gas release, the design of the diaphragm is extremely important. If the gas release speed is slow, it will cause a great degree of energy loss. The improvement of the diaphragm design can improve the energy loss and improve the energy transfer efficiency to a certain extent, thereby maximizing the projectile speed.

[0005] Therefore, the present invention aims to start from the simplest aspect and optimize the diaphragm design used for high-pressure gas release of light gas guns, thereby improving the energy output efficiency to a certain extent. Summary of the invention

[0006] The purpose of the present invention is to provide a device and method for improving the energy transfer of a light gas gun to improve the above problems. In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present application provides a device for improving energy transfer of a light gas gun, comprising:

[0008] A light gas gun, comprising a powder chamber, a pump pipe, a high pressure section and a launch tube connected in sequence;

[0009] A diaphragm, arranged between the high-pressure section and the nozzle of the launch tube, is used to rupture under the action of high-pressure gas to release energy;

[0010] A projectile connected to one end of the diaphragm and used to receive the energy released when the diaphragm ruptures and accelerate;

[0011] The high-temperature and high-pressure gas generated by the combustion in the gunpowder chamber drives the piston in the pump tube, thereby compressing the light gas to the high-pressure section; when the light gas is compressed to a certain pressure, it can break through the diaphragm located at the connection between the high-pressure section and the launch tube, and then exert force on the projectile, so that the projectile obtains the highest initial velocity, thereby realizing energy transfer.

[0012] Preferably, the diaphragm is composed of a main body portion with a central circular disc shape and a serrated edge portion surrounding the edge thereof, wherein the serrated edge portion is ring-embedded at the connection of the pipe mouth.

[0013] Preferably, one end of the edge of the diaphragm is a circular film, the edge of one end of the diaphragm is a circular film, and the edge of the other end of the diaphragm is designed with a ring-embedded structure, which matches one end of the projectile to form a mortise and tenon connection.

[0014] Preferably, a mounting groove is provided at the inner wall between the high-pressure section and the launch tube orifice, and the mounting groove is arranged along the circumferential direction of the inner wall, wherein a space for accommodating a diaphragm is provided in the mounting groove, and the diaphragm ring is embedded in the mounting groove.

[0015] Preferably, a diaphragm is provided at the connection between the high pressure section and the launch tube of the two-stage light gas gun.

[0016] Preferably, the high-pressure section, the launch tube and the diaphragm constitute a high-speed launch device, and the high-speed launch device is a two-stage light gas gun.

[0017] Preferably, the diaphragm is provided with annularly distributed reinforcing ribs at its circumference, and the reinforcing ribs are evenly arranged and distributed along the circumference; the surface of the diaphragm is coated with an anti-wear coating; and the diaphragm is made of a high-strength and high-elasticity material.

[0018] In a second aspect, the present application also provides a method for improving the energy transfer of a light gas gun, comprising the following steps:

[0019] Step 1: Ignite gunpowder in the gunpowder chamber of the light gas gun to generate a large amount of high-temperature and high-pressure gas; burn gunpowder in the gunpowder chamber to generate high-temperature and high-pressure gas;

[0020] Step 2: The high-temperature and high-pressure gas generated by the powder chamber pushes the piston through the pump pipe, compressing the light gas to the high-pressure section;

[0021] Step 3: Under the push of the piston, the light gas is compressed to the high-pressure section. During this stage, the gas pressure continues to increase. When the gas pressure in the high-pressure section reaches a predetermined threshold, the diaphragm at the junction of the high-pressure section and the launch tube ruptures, exerting force on the projectile and pushing the projectile out along the launch tube at the highest speed.

[0022] Step 4: The projectile is launched after it has achieved the highest initial velocity, thereby achieving effective energy transfer.

[0023] The beneficial effects of the present invention are:

[0035] Embodiment 1:

[0036] In the field of light gas gun technology in the prior art, with the increasing demand for high-speed launch in fields such as military training, aerospace testing, and materials science, traditional light gas gun systems are facing challenges in efficiency and safety. Current technology mainly relies on the rapid release of chemical energy to drive projectiles, but these systems usually have problems such as low energy transfer efficiency, unstable launch speed, and insufficient safety. Existing solutions often use simple diaphragm designs, which are prone to incomplete or delayed rupture under high pressure, resulting in energy loss and reduced launch accuracy. In addition, these systems are relatively backward in material selection and structural design, and cannot meet the requirements for high performance and high reliability in modern applications. Therefore, this embodiment provides a device and method for improving the energy transfer of light gas guns, as follows:

[0037] See also Figure 1 and Figure 2 As shown, this embodiment provides a device for improving the energy transfer of a light gas gun, comprising:

[0038] A light gas gun, the light gas gun comprising a powder chamber 1, a pump pipe 2, a high pressure section 3 and a launch tube 4 connected in sequence;

[0039] The diaphragm 5 is arranged between the high-pressure section 3 and the tube mouth of the launch tube 4, and is used to rupture under the action of high-pressure gas to release energy;

[0040] A projectile 6 connected to one end of the diaphragm 5 for receiving the energy released when the diaphragm ruptures and accelerating;

[0041] The high-temperature and high-pressure gas generated by the combustion in the gunpowder chamber 1 drives the piston in the pump tube 2, thereby compressing the light gas to the high-pressure section 3; when the light gas is compressed to a certain pressure, it can break through the diaphragm 5 located at the connection port between the high-pressure section 3 and the launch tube 4, and then exert force on the projectile 6, so that the projectile 6 obtains the highest initial speed, thereby realizing energy transfer.

[0042] It should be noted that the diaphragm is made of high-strength and high-elastic materials. High-strength and high-elastic materials (such as polyester film or high-strength metal alloy, etc.) are selected to improve the stability and durability of the diaphragm under gas pressure. Materials with excellent elasticity are selected to ensure that the diaphragm can effectively transmit pressure without excessive deformation.

[0043] Specifically, the diaphragm 5 is composed of a main body portion with a central circular disc shape and a serrated edge portion surrounding the edge thereof, wherein the serrated edge portion is embedded in the connection of the pipe mouth.

[0044] Specifically, one end of the edge of the diaphragm 5 is a circular film, the edge of one end of the diaphragm 5 is a circular film, and the edge of the other end of the diaphragm 5 is designed with a ring-embedded structure, which matches one end of the projectile 6 to form a mortise and tenon connection. This can reduce the error of gas leakage to a certain extent. Prevent gas leakage, thereby improving energy transfer efficiency. Ensure the airtightness between the diaphragm and the gas cavity.

[0045] Specifically, a mounting groove is provided on the inner wall between the high-pressure section 3 and the nozzle of the launch tube 4, and the mounting groove is arranged along the circumferential direction of the inner wall, wherein a space for accommodating the diaphragm 5 is provided in the mounting groove, and the diaphragm 5 is ring-embedded in the mounting groove.

[0046] Specifically, the high-pressure section 3, the launching tube 4 and the diaphragm 5 constitute a high-speed launching device, and the high-speed launching device is a two-stage light gas gun.

[0047] In some optional embodiments, the diaphragm 5 is provided with annularly distributed reinforcing ribs at the circumference, and the reinforcing ribs are evenly arranged and distributed along the circumference to improve the strength and stability of the diaphragm.

[0048] Specifically, the surface of the diaphragm 5 is coated with an anti-wear coating to enhance its durability and reduce wear. Furthermore, the diaphragm 5 is made of high-strength and high-elasticity material, and the surface of the diaphragm is chemically plated or coated to improve the surface smoothness of the diaphragm, thereby reducing resistance and energy loss during gas flow.

[0049] In some optional embodiments, the thickness of the diaphragm is adjusted to appropriately reduce the thickness so as to balance strength and flexibility. An overly thick diaphragm will cause energy loss to a certain extent.

[0050] Furthermore, in terms of structural reinforcement of the diaphragm, a reinforcement structure is added to the diaphragm design, and annular reinforcement ribs are added at the circumference of the diaphragm, so that they are distributed in a ring shape and evenly arranged along the circumference, so as to be nested in the installation groove of the inner wall of the light gas gun, so as to improve the strength and stability of the diaphragm.

[0051] Furthermore, in the surface treatment of the diaphragm, chemical plating or coating is used on the surface of the diaphragm to improve the surface smoothness of the diaphragm, thereby reducing the resistance and energy loss during the gas flow process.

[0052] In summary, in the light gas gun system of the present invention, the design of the diaphragm 5 has been innovatively optimized, and a high-strength polyester film material is used to ensure reliability and durability when subjected to high-pressure gas. The ingenious combination of the circular disc-shaped body of the diaphragm and the serrated edge not only improves the response speed when ruptured, but also improves the energy transfer efficiency by increasing the rupture area. The serrated design of the edge has been precisely calculated to achieve instant rupture when the gas pressure reaches a certain level, while reducing the resistance to gas flow. In addition, the surface of the diaphragm has been specially chemically treated to increase the smoothness and further reduce the energy loss. The introduction of annular reinforcement ribs enhances the structural integrity of the diaphragm and prevents deformation under high pressure. The connection between the entire diaphragm and the projectile 6 adopts an innovative mortise and tenon ring embedding structure. This design not only ensures the stability of the connection, but also allows rapid energy transfer when the diaphragm ruptures, thereby significantly improving the projectile's launch speed and the overall system performance. These innovative design details work together to improve the energy transfer efficiency of the light gas gun and the safety of the system, reflecting the creativity and practicality of the present invention in diaphragm design.

[0053] Embodiment 2:

[0054] like Figure 3 As shown, this embodiment provides a method for improving the energy transfer of light gas guns, see Figure 3 The method comprises the following steps:

[0055] Step 1: Ignite gunpowder in the gunpowder chamber 1 of the light gas gun to generate a large amount of high-temperature and high-pressure gas; burn gunpowder in the gunpowder chamber 1 to generate high-temperature and high-pressure gas;

[0056] Step 2: The high-temperature and high-pressure gas generated by the powder chamber 1 pushes the piston through the pump pipe 2, compressing the light gas to the high-pressure section, and monitoring the dynamic position of the piston in real time;

[0057] Step 3: Under the push of the piston, the light gas is compressed to the high-pressure section 3. At this stage, the gas pressure continues to increase. When the gas pressure in the high-pressure section 3 reaches a predetermined threshold, the diaphragm 5 at the junction of the high-pressure section 3 and the launch tube 4 ruptures, exerting force on the projectile 6 and pushing the projectile 6 to be ejected along the launch tube 4 at the highest speed;

[0058] Step 4: The projectile is launched after it has achieved the highest initial velocity, thereby achieving effective energy transfer.

[0059] It can be understood that the gunpowder is ignited in the gunpowder chamber 1 to produce explosive gas. This step is the starting point of energy conversion, which converts chemical energy into heat and kinetic energy. The selection and proportion of gunpowder have a direct impact on the combustion efficiency and the speed of gas generation, thereby affecting the driving force of the piston; the explosive gas drives the piston to compress the light gas (such as hydrogen or nitrogen) in the pump tube 2. The selection of light gas is based on its lower density and high compressibility, which helps to store more energy in a smaller space. The design of the pump tube 2 must be able to withstand high pressure while ensuring the sealing of the gas to avoid energy loss; the design of the high-pressure section 3 needs to consider the strength and pressure resistance of the material, as well as the optimization of the internal structure for gas flow to reduce turbulence and friction losses; the use of high-strength and high-elasticity materials (such as polyester film) can improve the durability and reliability of the diaphragm, and the serrated edge design has It helps to rupture quickly and completely when the gas pressure reaches its peak, reducing energy loss; the diaphragm is installed in the installation groove of the inner wall of the light gas gun in a ring-embedded manner to enhance airtightness. This installation method not only improves the sealing of the system, but also reduces the friction between the diaphragm and the inner wall, protecting the inner wall from scratches; the diaphragm is chemically plated or coated to improve surface smoothness and reduce gas flow resistance. This treatment helps to improve the continuity and uniformity of gas flow, thereby reducing energy loss; annular reinforcement ribs are added to the circumference of the diaphragm to improve the strength and stability of the diaphragm, which helps the diaphragm maintain its shape under the action of high-pressure gas and prevent premature rupture or deformation; the rear end of the projectile is made of polymer material, whose mechanical parameters are lower than those of metal diaphragm, which reduces energy consumption and increases projectile speed. The elasticity and toughness of the polymer material help to absorb and transfer energy while reducing the impact on the system.

[0060] It should be noted that in terms of technical effects, these steps work together to improve the energy transfer efficiency and stability of the light gas gun system. By optimizing the diaphragm design and material selection, energy loss is reduced and the safety and accuracy of the experiment are improved. In practical applications, this optimized design can be applied to military training, aerospace testing, material testing and other fields to provide a high-precision and high-reliability launch system. In addition, these technologies can also be extended to other industrial and scientific research fields that require precise control and rapid response, such as automotive engine testing, hydraulic system control, etc., showing a wide range of application potential and innovative value.

[0061] Through this series of precisely controlled steps, the light gas gun system can efficiently convert chemical energy into kinetic energy of the projectile, achieving fast and accurate firing. The precise design and coordinated work of each step together improve the energy transfer efficiency of the entire system.

[0062] Specifically, the experimental process is briefly described as follows: the explosive gas in the powder chamber 1 can drive the piston to compress the light gas (usually hydrogen or nitrogen) in the pump tube 2, and after passing through the high-pressure section 3, the projectile in the launch tube 4 is ejected through the improved diaphragm 5.

[0063] Specifically, the left and right sides of the diaphragm adopt a circular disc design and use high-strength and high-elasticity materials (such as polyester film). The edge part adopts a serrated shape. At the same time, the inner wall of the light gas gun is provided with a mounting groove along the circumferential direction. The diaphragm is embedded in the mounting groove in a ring, which can enhance the air tightness to a certain extent. In addition, the use of elastic materials also improves the problem of the diaphragm scratching the inner wall of the light gas gun body to a certain extent, and the operation of the entire projectile will be more stable.

[0064] Specifically, detailed surface treatment of the diaphragm, using chemical plating or coating on the surface of the diaphragm, can improve the surface smoothness of the diaphragm, thereby reducing resistance and energy loss during gas flow.

[0065] Specifically, annular reinforcing ribs are added at the circumference of the diaphragm to be distributed in an annular shape and evenly arranged along the circumference, so as to be nested in the mounting groove of the inner wall of the light gas gun to improve the strength and stability of the diaphragm.

[0066] Specifically, the diaphragm and the rear end of the projectile are made of polymer materials, and the mechanical parameters are much lower than those of the metal diaphragm, which can reduce the energy consumption of the high enthalpy gas at the rear end of the projectile, which is conducive to increasing the speed of the projectile. Overall, the design of the diaphragm is optimized to enhance the airtightness and increase the energy transfer rate to a certain extent, while also improving the safety and accuracy of the experiment.

[0067] Traditional launch systems are often limited by the material and structural limitations of the diaphragm design, resulting in low energy conversion efficiency, unstable launch speed, and safety hazards under extreme conditions of use. The rupture mechanism of the diaphragm is not ideal, resulting in the inability to quickly and completely convert gas energy into projectile kinetic energy. In addition, the connection between the diaphragm and the projectile cannot remain stable under high-pressure impact, thereby affecting the overall launch performance. Therefore, the present invention includes but is not limited to the use of high-strength polyester film materials, which provide excellent tensile strength and heat resistance while maintaining light weight, and are particularly suitable for use in high-pressure gas environments, wherein the circular disc-shaped body design of the diaphragm helps to withstand pressure more evenly, and the serrated edge ensures that when the gas pressure reaches a certain level, the diaphragm can rupture quickly and synchronously, reducing the energy loss caused by asynchronous diaphragm rupture. Furthermore, the chemical treatment of the diaphragm surface not only improves its smoothness and reduces the resistance to gas flow, but also enhances its corrosion resistance and wear resistance, thereby extending the service life of the diaphragm. The design of the annular reinforcement ribs is another enhancement of the structural integrity of the diaphragm. It resists the impact of high-pressure gas by increasing the rigidity of the diaphragm, ensuring that the diaphragm will not be deformed or damaged during the launch process. Most importantly, the present invention adopts an innovative mortise and tenon ring embedded structure connection method, which not only provides strong mechanical connection strength, but also allows the diaphragm to quickly and efficiently transfer energy to the projectile when it ruptures, significantly improving the stability and reliability of the system. Through precise computer simulation and a series of physical tests, the diaphragm design of the present invention has been proven to provide consistent performance under various expected conditions of use, whether at normal temperature and pressure or in extreme high-pressure environments.

[0068] It should be noted that, regarding the system in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
