Description

Technical Field

[0001] The invention relates to a coil electromagnetic gun technology, more specifically, to a high-temperature superconducting coil missile electromagnetic gun device. Background Art

[0002] The current types of electromagnetic guns include rail electromagnetic guns, coil electromagnetic guns and reconnection electromagnetic guns. Among them, rail electromagnetic guns are relatively mature electromagnetic guns that countries around the world are competing to develop. Although my country's rail electromagnetic gun technology has already led the world level, rail electromagnetic guns have the defects of easy barrel ablation, large size, high cost and poor electrical efficiency. Therefore, rail electromagnetic guns have not been officially used in various countries so far.

[0003] The Chinese Patent Gazette has published an invention patent named "warship missile electromagnetic gun" with application number "2019111255384". It is a coil electromagnetic gun, which also has the problems of long barrel, large volume, high cost and poor electric efficiency. The bulky electromagnetic gun cannot be flexibly operated in a harsh war environment.

[0004] At present, the industrialization of high-temperature superconductors in my country is constantly improving, and the downstream applications of high-temperature superconducting products are also continuously opening up. High-temperature superconductors have zero resistance at extremely low temperatures, and current continuously exists in the superconducting coils. The super-strong magnetic flux of the superconducting coils does not consume electrical energy, which can improve the electric efficiency of electromagnetic guns, making the electromagnetic guns smaller in size, lower in cost, and longer in range. Therefore, the application of high-temperature superconducting products in coil electromagnetic guns is the direction of high-quality development of electromagnetic guns.

[0005] In order to accurately strike enemy military targets, modern warfare mainly uses various conventional missiles and drones for active attacks. However, conventional missiles and drones have the defects of high cost and easy interception. The cost of electromagnetic missiles launched by electromagnetic guns is much lower than that of conventional missiles and drones. Electromagnetic missiles are inertial gliding stealth missiles with small size and high speed. Without the burning light and heat radiation of conventional missiles, the enemy cannot detect and intercept electromagnetic missiles. Summary of the invention

[0012] In order to quickly install the high-temperature superconducting coil, the high-temperature superconducting coil and the superconducting electromagnetic missile are a split installation structure, the inner circle of the high-temperature superconducting coil and the outer circle of the explosive cartridge are loosely fitted, a left barb plate is provided at the left end of the tail shell, and a right barb plate is provided at the right end of the tail shell; before launching the superconducting electromagnetic missile, the high-temperature superconducting coil is taken out from the extremely low temperature liquid nitrogen, the high-temperature superconducting coil is inserted from the rear ends of the left and right tail wings and the upper and lower tail wings, and is inserted into the explosive cartridge through the left barb plate and the right barb plate, the front end of the high-temperature superconducting coil is close to the rear end step of the warhead shell, and after the left and right barb plates are popped up, the front ends of the left and right barb plates are blocked at the rear end of the high-temperature superconducting coil; the outer circle of the high-temperature superconducting coil is slightly smaller than the inner circle of the barrel, and the superconducting electromagnetic missile is installed after the high-temperature superconducting coil is installed When the superconducting electromagnetic missile enters the barrel, the friction force formed by the tangency between the lower end of the outer circle of the high-temperature superconducting coil and the lower end of the inner circle of the barrel stabilizes the position of the superconducting electromagnetic missile. When the superconducting electromagnetic missile is magnetically suspended in the inner circle of the barrel, a small annular air gap is formed between the outer circle of the high-temperature superconducting coil and the inner circle of the barrel. In order for the reflective proximity switch to accurately identify the thickness of the annular air gap, the thickness of the annular air gap is much smaller than the thickness of the annular air gap between the warhead casing and the tail casing and the inner circle of the barrel. When the launch button is pressed by hand, the launch relay switch is closed, and the high voltage of the high-voltage lithium battery pack is transmitted to multiple independent control drive units through the positive transmission copper bus and the negative transmission copper bus. When the high-temperature superconducting coil approaches multiple reflective proximity switches, the multiple reflective proximity switches are turned on, triggering multiple high-power switch modules. The high-temperature superconducting coil is turned on, and multiple electromagnetic coils close to the high-temperature superconducting coil are connected to a high-voltage DC power supply. The multiple electromagnetic coils generate multiple strong circular electromagnetic fields in the same direction through a strong current. The multiple circular electromagnetic fields induce the high-temperature superconducting coil. The resistance of the high-temperature superconducting coil is zero. The strong current induced by the high-temperature superconducting coil generates a strong superconducting magnetic field in the coaxial direction. The positions of the multiple circular electromagnetic fields lag behind the position of the superconducting magnetic field. The multiple circular electromagnetic fields and the superconducting magnetic field repel each other with the same polarity, generating a vector angle forward expansion force. The multiple circular electromagnetic fields push the superconducting magnetic field forward, and the high-temperature superconducting coil moving forward approaches the reflective proximity switch at the front end. A new circular electromagnetic field is generated at the front end of the multiple circular electromagnetic fields. The high-temperature superconducting coil moving forward leaves the back The reflective proximity switch at the end, the circular electromagnetic field at the rear end of the multiple circular electromagnetic fields disappears. Under the control of the reflective proximity switch, the multiple circular electromagnetic fields synchronously follow the high-temperature superconducting coil to move forward. The positions of the multiple circular electromagnetic fields always lag behind the positions of the superconducting magnetic field. The vector angle of the repulsive force is always forward, always pushing the superconducting coil to move forward; the superconducting electromagnetic missile moves forward at high speed in the barrel under the magnetic suspension state. The superconducting electromagnetic missile is non-contact with the barrel, and there is no friction resistance and friction heat, which avoids barrel ablation. The superconducting magnetic field is equal to the strength of the circular electromagnetic field, and the superconducting magnetic field does not consume electrical energy. Therefore, the electric efficiency of the high-temperature superconducting coil missile electromagnetic gun device is much greater than the 50% electric efficiency of the electromagnetic gun in the prior art;The superconducting electromagnetic missile is instantly accelerated to hypersonic speed in the 20-meter-long barrel. After the superconducting electromagnetic missile flies out of the barrel, it decelerates and glides in the air. The superconducting electromagnetic missile glides for more than 200 kilometers relying on inertia.

[0013] Furthermore, the superconducting electromagnetic missile is a fire-and-forget intelligent missile. When the superconducting electromagnetic missile accelerates in the barrel, the superconducting conductive magnetic field triggers the Hall sensor to turn on, and the Hall sensor turns on the power of the intelligent controller and the tail controller. The gyro sensor and the combined guidance sensor automatically adjust the horizontal attitude of the superconducting electromagnetic missile through the intelligent controller and the tail controller, and automatically search for targets. During the process of attitude adjustment and target search, the missile tail constantly corrects the direction of travel by the gyro sensor and the combined guidance sensor; the upper and lower tail motors and the left and right tail motors are harmonic reduction permanent magnet motors, and the tail controller controls the upper and left and right tails and the lower and left and right tails as well as the upper and lower tails through the upper and lower tail motors and the left and right tail motors. When the upper and left and lower tails swing left and right, the high-speed flying superconducting electromagnetic missile turns left and right in the air. When the upper and lower tails swing up and down, the superconducting electromagnetic missile turns up and down in the air. After the superconducting electromagnetic missile accurately hits the military target, it hits the bomb fuse in the warhead, detonating the explosive cartridge to explode.

The multiple first end curves and tail end curves are located within the outer circumference of the tubular coil winding. The outer circle of the tubular coil winding and the inner circle of the seamless steel pipe are loosely fitted. The tubular coil winding is assembled into the seamless steel pipe. The multiple equally divided positive long wire holes are aligned with the multiple equally divided tail long wire holes, and the multiple equally divided negative long wire holes are aligned with the multiple equally divided first end long wire holes. The first end curves of the multiple electromagnetic coils are hooked out of the multiple negative long wire holes respectively, and the tail end curves of the multiple electromagnetic coils are hooked out of the multiple positive long wire holes respectively.

[0015] Furthermore, the upper ends of the multiple high-power switch modules are provided with input wiring piles and tail wire wiring piles, the lower ends of the multiple high-power switch modules are provided with positive power wiring piles, the right end of the high-power switch module is provided with a positive power transmission copper bus, the output lines of the multiple reflective proximity switches are respectively welded to the corresponding input wiring piles, the tail end curves of the multiple electromagnetic coils are respectively welded to the corresponding tail wire wiring piles, the positive power wiring piles of the multiple high-power switch modules are welded to the positive power transmission copper bus as a whole, and the head end curves of the multiple electromagnetic coils are welded to the negative pole. At the left end of the transmission copper busbar, the positive and negative electrodes of multiple independent control drive units are connected in parallel to the positive transmission copper busbar and the negative transmission copper busbar. The positive output line of the high-voltage DC power supply energy storage box is connected to the positive transmission copper busbar through a high-power relay, and the negative output line of the high-voltage DC power supply energy storage box is connected to the negative transmission copper busbar. The output line of the launch button is connected to the input end of the high-power relay; the left and right launch buttons and the left and right high-power relays each independently control the long coil gun barrel to launch missiles, and the left and right long coil gun barrels share a high-voltage DC power supply energy storage box.

[0016] Furthermore, the intensity of the superconducting magnetic field is equal to that of the annular electromagnetic field, and the superconducting magnetic field does not consume electrical energy. Therefore, the electric efficiency of the high-temperature superconducting coil missile electromagnetic gun device is high. Under the conditions of the same projectile mass and projectile range, the power requirement of the high-voltage DC power supply energy storage box is lower than the power supply power requirement of the existing electromagnetic gun. In order to meet the instantaneous electrical power of thousands of megawatts required by the high-temperature superconducting coil missile electromagnetic gun device, the high-voltage DC power supply energy storage box can instantly output a DC power supply with a voltage of thousands of volts and a current of tens of thousands of amperes. The high-voltage farad capacitor is connected in parallel with the high-voltage lithium battery pack. When the current of tens of thousands of amperes is instantly output, the high-voltage farad capacitor and the high-voltage lithium battery pack are discharged in parallel, so that the voltage drop of thousands of volts is small. After the high-voltage farad capacitor is discharged, the high-voltage lithium battery pack continues to charge it to reserve the next discharge. The electric energy of the electric launch, the high-voltage lithium battery pack can be repeatedly charged after the energy is used up; the cross-sectional area of ​​the electromagnetic coil enameled copper wire, the cross-sectional area of ​​the positive transmission copper bus and the negative transmission copper bus, and the cross-sectional area of ​​the positive output line and the negative output line must all meet the requirements of tens of thousands of amperes of current; the strong magnetic force of like-sex repulsion between the superconducting electromagnetic missile and the barrel produces a strong expansion pressure in the barrel, and the expansion pressure acts on the inner circle of the seamless steel pipe through the tubular coil group. The thickness of the seamless steel pipe wall should meet the requirements of the expansion pressure. The forward expansion pressure of the vector angle pushes the superconducting electromagnetic missile, causing the long coil gun barrel to produce a strong recoil force. Therefore, when launching a superconducting electromagnetic missile, the four wheels of the launch vehicle are all in a braking state; the length of the long coil gun barrel is set to 20 meters, and the range of the superconducting electromagnetic missile can reach 200 kilometers.

[0017] Furthermore, multiple reflective proximity switches control the power on and off of multiple electromagnetic coils through multiple high-power switch modules. When the front end of the high-temperature superconducting coil approaches the first reflective proximity switch, the second, third and fourth reflective proximity switches behind are all within the proximity range of the high-temperature superconducting coil, and the first, second, third and fourth electromagnetic coils at the rear end of the first reflective proximity switch are energized. The annular electromagnetic fields of the four electromagnetic coils lag behind the annular electromagnetic field of the high-temperature superconducting coil, and the lagging annular electromagnetic field repels the annular electromagnetic field of the front high-temperature superconducting coil. When the rear end of the high-temperature superconducting coil moves forward to leave the fourth reflective proximity switch, the fourth electromagnetic coil is de-energized, and the first, second and third electromagnetic coils are energized according to the embodiment of the present invention. Even when energized, the annular electromagnetic fields of the three electromagnetic coils still lag behind the annular electromagnetic field of the high-temperature superconducting coil. When the front end of the high-temperature superconducting coil approaches the reflective proximity switch in front of the first reflective proximity switch, the three rear reflective proximity switches are all within the proximity range of the high-temperature superconducting coil, and the annular electromagnetic fields of the four electromagnetic coils repel the annular electromagnetic field of the front high-temperature superconducting coil, and the lagging annular electromagnetic field repels the annular electromagnetic field of the front high-temperature superconducting coil over and over again; the independent control drive units outside the proximity range of the high-temperature superconducting coil are all in a power-off state, the superconducting electromagnetic missile is accelerated non-contact in the barrel, and multiple independent control drive units are energized in an instant. Therefore, the long coil barrel will not generate high temperature and barrel ablation will not occur.

[0018] Furthermore, the liquid nitrogen insulation tank is a cylindrical stainless steel insulation tank with an outer shell and an inner liner, the inner liner is located in the middle of the outer shell, a closed vacuum insulation cavity is provided between the outer shell and the inner liner, a plastic insulation cover is provided at the tank mouth at the upper end of the liquid nitrogen insulation tank, a T-shaped insulation plug is provided in the middle of the plastic insulation cover, a plurality of tightly fitting flexible sealing rings are provided between the T-shaped insulation plug and the tank mouth, a closed vacuum insulation cavity is provided in the middle of the T-shaped insulation plug, a handle is provided at the upper end of the plastic insulation cover, a round base is welded at the lower end of the liquid nitrogen insulation tank, a lower round table is provided in the center of the bottom of the liquid nitrogen insulation tank, an upper round table is provided in the center of the lower end of the T-shaped insulation plug, and the upper and lower parts of the inner circle of the high-temperature superconducting coil are provided. The lower ends are respectively inserted into the outer circles of the upper and lower truncated tables. The high-temperature superconducting coil is stabilized in the middle of the liquid nitrogen insulation tank. The liquid nitrogen insulation tank is filled with liquid nitrogen. The horizontal plane height of the liquid nitrogen is greater than the height of the high-temperature superconducting coil. The carrying handle can move the liquid nitrogen insulation tank. The missile launch operator wears antifreeze gloves to launch the superconducting electromagnetic missile. First, hold the handle with both hands, step on the round base with both feet, lift up with both hands, slowly pull out the plastic insulation cover, take out the cooled high-temperature superconducting coil by hand, put the plastic insulation cover back on, and quickly load the cooled high-temperature superconducting coil into the outer circle of the explosive cartridge before loading the superconducting electromagnetic missile into the gun barrel.

[0019] The benefits of the high-temperature superconducting coil missile electromagnetic gun device are as follows: the cost of superconducting electromagnetic missiles is much lower than that of conventional missiles and drones. Superconducting electromagnetic missiles are inertially gliding stealth missiles without burning light and heat radiation. Superconducting electromagnetic missiles are small in size and fast in speed, and the enemy cannot detect and intercept them. Conversely, it is very cost-effective to use superconducting electromagnetic missiles to intercept the enemy's expensive conventional missiles and drones, especially for dealing with drone swarms. The fundamental reason why electromagnetic guns with existing technology in my country have not been formally applied is that the electric efficiency of electromagnetic guns is only 50%. The low electric efficiency leads to a large size of the overall electromagnetic gun, high cost, heating of the gun barrel, and ablation of the gun barrel. The high-temperature superconducting coil saves magnetic flux electric energy, improves the electric efficiency of the high-temperature superconducting coil missile electromagnetic gun device, reduces costs, and avoids ablation of the gun barrel. , saving lithium batteries, reducing the size of the high-voltage DC power storage box, and reducing the size of the overall launch vehicle, making the launch vehicle flexible and maneuverable on the battlefield; the electromagnetic gun barrel has a simple structure, is easy to produce, and has low cost; the production of a large number of high-temperature superconducting coils is conducive to promoting the downstream application of high-temperature superconducting products, and the high-temperature superconducting coil is small in size and does not occupy the effective space of the missile, so that the superconducting electromagnetic missile has sufficient explosive space, guidance space and intelligent control space, and realizes the superconducting electromagnetic missile to carry out artificial intelligence-controlled precise strikes on enemy military targets; the high-temperature superconducting coil missile electromagnetic gun device is a combination of high-temperature superconducting coil and coil electromagnetic gun technology, which has promoted the innovation of the missile launch system and provided a cost-effective long-range strike means for future battlefields, enabling it to take the lead in the military science and technology competition and reshape the form of modern warfare.
