Description

Technical Field

[0001] The invention relates to a cannon, in particular to a cannon which is launched by hydraulic power. Background Art

[0002] Traditional artillery uses the impact force formed by the rapid expansion of explosives in the barrel to act on the launch load, pushing the launch load out of the barrel to generate initial velocity. Its advantages are mature technology and high reliability. Its disadvantages are that to increase the mass and initial velocity of the launch load, it is necessary to increase the amount of explosives, but the increase in the amount of explosives also leads to an increase in the risk of bursting. In addition, there are also shortcomings such as the initial velocity of the launch load is not easy to adjust, the cost of use is high, and a large amount of explosives stored in an actual combat environment are easy to be hit and cause sympathetic explosion. With the development of science and technology, electromagnetic railguns have also become a new concept weapon that countries around the world pay attention to and develop. The electromagnetic railgun consists of two parallel conductive rails, and the launch load is clamped between the two rails through an adapter. The two rails are connected to the power supply, and the current flows from one rail to the adapter and then to the other rail to generate a strong magnetic field. The magnetic field interacts with the current to generate a strong Lorentz force that pushes the adapter to drive the launch load to accelerate and glide until it leaves the railgun at high speed. The electromagnetic railgun has many advantages, such as the ability to flexibly adjust the launch load's initial velocity by controlling the input current, lower unit launch energy cost of electric energy than that of gunpowder launch, higher initial velocity, and flexible range change. However, the electromagnetic railgun also has prominent disadvantages, such as the life limit of the launch rail, the extremely high current passing through the launch rail during the launch process causing ablation; in order to reduce the ablation caused by contact resistance, the adapter and the launch rail need to be installed closely together, and the adapter causes friction damage to the launch rail during the launch process; the high-voltage arcing at the moment when the launch load and the adapter leave the launch rail will also cause ablation of the launch rail. Therefore, people are also actively exploring alternative and new concept launch guns that have all the advantages of the electromagnetic railgun and can effectively eliminate its defects and shortcomings. Summary of the invention

[0003] The present invention provides a cannon with rapid and continuous firing, high firing speed, adjustable firing speed, low unit firing energy cost, no high-temperature flame leakage and ablation, long barrel service life, and hydraulic-electric power firing. In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cannon using liquid-electric power for launching, comprising a gun barrel, a liquid-electric effect generator, a high-power pulse power supply, a liquid supply device, and a launch load, wherein the liquid-electric effect generator is respectively fixedly installed at the starting end of the gun barrel and on both sides of the extending direction of the gun barrel symmetrically, and the launch load is loaded into the gun barrel before launching; the liquid-electric effect generator is a tubular object equipped with a liquid level sensor and a generator plugging cover, and the open end is located on the inner side of the gun barrel, the generator plugging cover is used to seal the tube body to ensure that liquid can be stored in the tube body, and the generator plugging cover is located on the inner part of the tube body and is equipped with a pair of discharge electrodes, the discharge electrodes pass through the generator plugging cover and are connected to the outer power supply end, and the liquid replenishment port runs through the inner and outer sides of the generator plugging cover for replenishing liquid into the liquid-electric effect generator; the high-power pulse power supply is respectively connected to the power supply end on each liquid-electric effect generator through a cable; the liquid supply device is respectively connected to the liquid replenishment port on each liquid-electric effect generator through a pipeline.

[0004] Furthermore, the high-power pulse power supply can output high-voltage and high-power pulse current to each electrohydraulic effect generator through the power supply end on the cable and the generator cover according to the set timing.

[0005] Furthermore, the liquid supply device can replenish the working fluid liquid through the pipeline and the liquid replenishing port on the generator plug cover when the liquid level of the liquid level height sensor in the liquid-electric effect generator is lower than the set value.

[0006] Furthermore, the discharge electrode in the electrohydraulic effect generator produces an electrohydraulic effect with the liquid under the action of high-voltage and high-power pulse current, generating a high-speed jet of a vapor-liquid mixture and forming a pressure of up to hundreds of MPa, which is transmitted to the gun barrel through the open end of the electrohydraulic effect generator tube.

[0007] Furthermore, the gun barrel is selected to be smoothbore or rifled according to the type of launch load.

[0008] Furthermore, the launch load may be the warhead of a conventional artillery shell. When launching a fin-stabilized discarding sabot projectile, a guided artillery shell or a missile, the launch load is a combination of an adapter adapted to the inner diameter of the gun barrel and the warhead / missile.

[0009] Furthermore, by adding hydraulic-electric effect generators in pairs symmetrically along the extension direction of the gun barrel, the initial launch velocity and the throwing mass can be increased while ensuring a smooth launch impact.

[0010] A method for using a cannon using hydraulic power to launch:

[0011] First, the launching load is loaded into the starting end of the gun barrel, and the liquid supply device injects liquid into each electrohydraulic effect generator through the pipeline and the liquid replenishing port on the generator plug cover, and the high-power pulse power supply stores electrical energy.

[0012] Afterwards, the high-power pulse power supply outputs high-voltage and high-power pulse current to the hydraulic-electric effect generator installed at the starting end of the barrel through the power supply end on the cable and the generator cover. The high-speed jet of vapor-liquid mixture generated by the hydraulic-electric effect generator acts on the rear end of the launch load, and the thrust generated accelerates the launch load in the barrel. During the flight of the launch load in the barrel, the high-power pulse power supply outputs high-voltage and high-power pulse current to the hydraulic-electric effect generators located on both sides of the barrel in turn and in a timely manner through the power supply end on the cable and the generator cover, ensuring that the high-speed jet of vapor-liquid mixture generated by the symmetrical hydraulic-electric effect generators on both sides just acts on the rear end of the launch load, driving the launch load to continuously accelerate in the barrel.

[0013] Finally, the launch load reaches the designed initial launch velocity and leaves the barrel.

[0014] The present invention uses a hydraulic effect generator as a launch power source, and the hydraulic effect generator is symmetrically fixedly installed at the starting end of the gun barrel and on both sides of the gun barrel in the extension direction. The launch load is loaded in the gun barrel before launching, and a high-voltage and high-power pulse current is used to trigger the liquid gap discharge in the hydraulic effect generator, so that the liquid is instantly and violently vaporized and plasmatized to form a high-speed shock wave with a pressure of hundreds of megapascals or more, which is transmitted to the gun barrel through the opening end of the hydraulic effect generator tube body, and the launch load in the gun barrel is driven to accelerate along the extension direction of the gun barrel. The hydraulic effect generators on both sides of the gun barrel are excited in turn to ensure that the generated gas-liquid mixed state high-speed jet just acts on the rear end of the launch load, driving the launch load to continuously accelerate in the gun barrel. A cannon using hydraulic power for launching has the advantages of fast and continuous launching, high launching speed, adjustable launching speed, low unit launching energy cost, no high-temperature flame leakage and ablation, and long gun barrel service life, which can effectively make up for the defects and deficiencies of traditional guns and electromagnetic rail guns.

The generator plugging cover 21 is located in the inner part of the tube body and is equipped with a pair of discharge electrodes 211. The discharge electrode 211 passes through the generator plugging cover 21 and is connected to the outer power supply end 213. The liquid replenishing port 212 runs through the inside and outside of the generator plugging cover 21 and is used to replenish liquid into the liquid-electric effect generator 2; the high-power pulse power supply 3 is connected to the power supply end 213 on each liquid-electric effect generator 2 through a cable; the liquid supply device 4 is connected to the liquid replenishing port 212 on each liquid-electric effect generator 2 through a pipeline.

[0025] Furthermore, the high-power pulse power supply 3 can output high-voltage and high-power pulse current to each electrohydraulic effect generator 2 through the power supply terminal 213 on the cable and the generator cover 21 according to the set timing.

[0026] Furthermore, the liquid supply device 4 can replenish the working fluid liquid through the pipeline and the liquid replenishing port 212 on the generator plug cover 21 when the liquid level of the liquid level sensor in the electrohydraulic effect generator 2 is lower than the set value.

[0027] Furthermore, the discharge electrode 211 in the electrohydraulic effect generator 2 generates an electrohydraulic effect with the liquid under the action of high-voltage and high-power pulse current, generating a high-speed jet of a vapor-liquid mixture and forming a pressure of hundreds of MPa or more, which is transmitted to the barrel 1 through the open end of the electrohydraulic effect generator 2.
