Description

[0001] 1. Name: A high-speed torpedo.

[0002] 2. Technical field: The present invention mainly relates to the military field, and in particular to a torpedo with a new structure.

[0003] 3. Background technology: The present invention originates from the thinking about the Russian "Storm" supercavitating torpedo. Torpedoes require high speed and high maneuverability, but high speed will be subject to huge seawater resistance in seawater. To obtain high speed, a super-strong power system is required. The torpedo is small in size, and it is difficult to provide super-strong power. The Russian "Storm" supercavitating torpedo can produce supercavitation, which is equivalent to flying in the air, greatly reducing resistance and increasing speed. However, the "Storm" supercavitating torpedo has three weaknesses. First, it is difficult to produce cavitation during the startup phase, and additional power is required to push the torpedo to a high-speed state to produce cavitation; second, it is difficult to maintain the cavitation shape, and the cavitation needs to wrap the torpedo as a whole and have sufficient cavitation space; third, it is difficult to turn in the cavitation state, and the maneuverability is insufficient. The present invention designs a new projectile structure that can effectively solve the above problems.

[0004] 4. Content of the invention: The present invention designs a torpedo of a new structure. The power system adopts a solid fuel or liquid fuel rocket engine. High-temperature and high-pressure gas is drawn out from the nozzle position at the tail of the projectile, and introduced into the front of the projectile through a high-temperature and high-pressure gas cooling pipeline. Because the projectile is relatively long, the high-temperature and high-pressure gas cooling pipeline also has sufficient length to cool the high-temperature and high-pressure gas. The cooled high-pressure gas is filtered through an air filter and supplied to a high-pressure gas pipeline, which is then supplied to a high-pressure gas injection module. The high-pressure gas injection module is composed of a large number of flat capillary nozzles, which spray high-speed airflow to the rear of the projectile, forming a very thin high-speed backward-flowing air film on the surface of the projectile. This air film can greatly reduce the resistance encountered by the projectile when it moves forward. The high-pressure gas injection module is composed of a plurality of modules, which are connected by docking ports similar to wall bricks and pasted on the surface of the projectile.

[0005] 5. The technical solution adopted by the present invention is: high-temperature and high-pressure gas is drawn from the nozzle position at the tail of the projectile, introduced into the front of the projectile through the high-temperature and high-pressure gas cooling pipeline, filtered by the air filter and supplied to the high-pressure gas pipeline, and then supplied to the high-pressure gas injection module by the high-pressure gas pipeline, and the gas generated by itself is used to replace the cavitation gas that the cavitation torpedo needs to generate at high speed, thereby solving the problem of the source of the cavitation gas of the torpedo. The high-pressure gas injection module is composed of a large number of flat capillary nozzles, which spray high-speed airflow to the rear of the projectile, forming a very thin high-speed backward-flowing air film on the surface of the projectile. The use of this air film can greatly reduce the resistance of the projectile when it moves forward, thereby solving the problem of the large resistance of the torpedo in water. The large number of flat capillary nozzles on the surface of the torpedo can spray a large amount of high-speed gas backward, and the presence of a large amount of gas solves the problem of unstable bubble structure of the cavitation torpedo. The steering nozzle is used to achieve high-maneuver turning, because the gas is generated by itself, and turning does not affect the existence of the air film, thereby solving the problem that the "Storm" supercavitating torpedo is difficult to turn at high speed.

[0006] 6. Compared with the prior art, the present invention has the following beneficial effects: using its own gas to generate an air film on the surface of the torpedo, the gas can be generated simultaneously with the operation of the engine, no additional starting auxiliary equipment is required, the structure is simple, and the starting speed is fast. The gas ejected backward at high speed generates an air film, and the existence of the air film effectively reduces the resistance of seawater, so that high-speed navigation can be achieved. The existence of the air film is not affected when turning, and the shape of the air film changes little. High-speed maneuvering turning can be achieved with the assistance of the steering nozzle. 7. Description of the drawings:

[0007] Figure 1 : Schematic diagram of overall structural layout

[0008] Figure 2 :Schematic diagram of high-pressure gas injection module DETAILED DESCRIPTION

[0009] 1. System overall structure design and working principle

[0010] like Figure 1 As shown in the schematic diagram of the overall structural layout, the system consists of two parts: the missile system and the jet system.

[0011] 1. Projectile system:

[0012] The power system uses a solid or liquid rocket engine, and the rest of the parts are the seeker, warhead and other parts of traditional torpedoes. Traditional torpedoes are propelled by propellers, which are subject to great resistance from seawater and slow speed.

[0013] 2. Jet system

[0014] like Figure 2As shown in the schematic diagram of the high-pressure gas injection module, high-temperature and high-pressure gas is drawn out from the nozzle position at the tail of the projectile, introduced into the front of the projectile through the high-temperature and high-pressure gas cooling pipeline, and supplied to the high-pressure gas pipeline after being filtered by the air filter, and then supplied to the high-pressure gas injection module from the high-pressure gas pipeline. The high-pressure gas injection module is composed of a large number of flat capillary nozzles, which spray high-speed airflow to the rear of the projectile, forming a very thin layer of high-speed backward-flowing air film on the surface of the projectile. This layer of air film can greatly reduce the resistance encountered by the projectile when moving forward. Because the gas is self-generated, turning does not affect the existence of the air film, and high-maneuverability turning is achieved by using the steering nozzle. The high-pressure gas injection module is composed of multiple modules, similar to wall tiles connected by docking interfaces and pasted on the surface of the projectile.

[0015] 2. System Working Process

[0016] like Figure 1 As shown in the schematic diagram of the overall structural layout, because the torpedo needs to be used in water, the tail nozzle needs to be waterproofed, and the main pipeline for the high-pressure gas circulation also needs to have a one-way valve for waterproofing to prevent seawater from pouring into the torpedo. When started, the rocket engine ignites, and the high-temperature and high-pressure gas breaks through the waterproof material and sprays out from the tail nozzle. At this time, a large amount of high-temperature and high-pressure gas automatically prevents seawater from flowing back. The high-temperature and high-pressure gas is drawn out from the nozzle position at the tail of the projectile, and the high-temperature and high-pressure gas enters the cooling pipe. Through long-distance pipes and auxiliary cooling measures, the high-temperature and high-pressure gas can be cooled. After cooling, the high-pressure gas is supplied to the high-pressure gas injection module through the pipe.

[0017] The high-pressure gas injection module is composed of a large number of flat capillary nozzles, which spray high-speed gas toward the tail of the projectile to form a layer of air film on the surface of the torpedo. Because the rocket engine will spray a large amount of gas when it is working, a part of the high-pressure gas is drawn from the tail nozzle to supply the high-pressure gas injection module. The demand for this part of gas is not large and has little impact on the overall thrust. The gas ejected by the high-pressure gas injection module can form a large volume of air space on the surface of the torpedo. When the torpedo is traveling at high speed, cavitation will also be generated in the head of the torpedo itself. The superposition of the two parts of the air space will have enough air space to supply the rocket engine, so there is basically no need to install a cavitation generator on the head of the torpedo.

[0018] The torpedo is equipped with steering nozzles at the front and rear, which can coordinate with each other to perform high-maneuverability turns according to computer instructions.

[0019] 3. Existing problems and solutions

[0020] 1. Structural design of the nozzle: The size of the flat capillary nozzle needs to be designed according to the gas consumption. The larger the cross-sectional area of ​​the nozzle, the more air intake is required. This is because the main function of the gas ejected by the high-pressure gas injection module is to form a layer of air film to keep the seawater out of the air film, create air space, and reduce resistance and provide working space for the engine. The high-pressure gas injection module is not required to generate thrust. The main thrust is the rocket engine. Therefore, the gas injection angle, injection volume, etc. can be designed according to actual needs. Professionals are required to perform calculations and experiments to find the most suitable parameters.

[0021] 2. Gas extraction from the nozzle: whether to extract the gas from the tail nozzle or from the combustion chamber. The gas extraction from the combustion chamber has a higher pressure, but it may affect the operation of the engine. Therefore, a reasonable position is required to extract the gas, that is, a gas with a pressure and volume that meets the requirements without affecting the operation of the engine.

[0022] 3. Missiles can also use this structure to form an air film on the outer surface of the missile. The high-speed air film ejected backward can reduce the air resistance of the missile and isolate the air to avoid high temperature. This structure can be used for torpedoes and missiles. The projectile is a torpedo in the water and a missile in the air. Because the outer surface of the projectile is protected by an air film, it can fly lower when flying over the sea, and can dive into the water at any time, or jump from the water to the air at any time. If it is made into a universal projectile, professionals are required to reasonably design the nozzle parameters.

[0023] IV. Conclusion

[0024] The high-temperature and high-pressure gas ejected by the rocket engine is introduced into the front of the projectile through the high-temperature and high-pressure gas cooling pipeline, and then supplied to the high-pressure gas injection module after being filtered by the air filter. The high-pressure gas injection module is composed of a large number of flat capillary nozzles, which eject high-speed airflow to the rear of the projectile, forming a very thin layer of high-speed backward-flowing air film on the surface of the projectile. This air film can greatly reduce the resistance encountered by the projectile when moving forward. The large number of flat capillary nozzles on the surface of the torpedo can eject a large amount of high-speed gas backward. The presence of a large amount of gas solves the problem of unstable bubble structure of cavitation torpedoes. High-maneuverability turns are achieved by using steering nozzles. Because the gas is self-generated, turning does not affect the existence of the air film, which solves the problem that supercavitation torpedoes are difficult to turn at high speed.
