Break through the monopoly! China's another powerful country with heavy equipment unveiled
Recently, another powerful country in China has unveiled its heavy machinery, which is the shaftless pump propulsion technology developed under the leadership of Academician Ma Weiming. It is reported that China's shaftless pump propulsion technology is quite powerful, capable of minimizing submarine noise and even leading the United States in technology. At the same time, it has also broken through the Western monopoly on submarine power technology! So how difficult is the research and development of shaftless pump pushing technology?
How did China achieve independent research and development? Now the difficulty of this technology has been exposed. It is understood that in order to develop the shaftless pump propulsion technology, Academician Ma Weiming led a team to conduct several years of continuous research and development, and ultimately achieved success. The new shaftless pump propulsion technology will be used on China's next generation of nuclear submarines. For the achievements made by China through its own efforts, even the United States has nothing to say this time.The picture shows a traditional shaft pump pushing submarineFor China, the application of shaftless pumping technology is of great significance. Currently, shaftless pumping technology is mainly used in submarines, and its biggest feature is the ability to reduce submarine noise. Traditional shaft pumping technology generates significant noise during operation.At present, countries such as Europe and the United States have basically no good solution to solve the noise problem of the power system. They can only rely on modifying the submarine model and using more advanced materials on the surface to reduce the overall noise of the submarine. China is no exception. China's nuclear submarines have always been troubled by noise problems, and the United States even jokingly claims that as soon as the sonar radar is turned on, a newly departed Chinese submarine can be detected.However, due to the late start of submarine technology, China is unable to reduce submarine noise through materials and modifications like Western countries, which poses a huge threat to China's nuclear submarines. After all, submarines need to be hidden deep in the sea at all times.For hidden weapons that only appear when necessary, the louder the noise, the easier it is for people to discover. Once the submarine's whereabouts are locked, not only is it almost impossible for the submarine to escape, but its strategic value will also be lost. This is quite fatal for the backbone nuclear submarines of sea based nuclear forces, and the emergence of shaftless pumping technology has solved this problem for China.The picture is an imaginary image of a submarine propelled by a shaftless pumpDue to the fact that shaftless pumping technology does not rely on shafts to drive the blades, the blades are directly arranged in the guide pipe. Without shaft obstruction, the noise of the submarine power system will become very small. Not only will the noise be reduced, but the operating efficiency of the submarine power system will also be greatly improved. Compared with shaft pumping technology, shaftless pumping technology reduces the water resistance on the hull, which can greatly reduce the energy loss of the submarine power system. Submarines using shaftless pumping technology have a propulsion efficiency about one fourth higher than those using traditional thrusters.Academician Ma Weiming has brought not only shaftless pump propulsion technology to China, but also ship electric propulsion systems and electromagnetic catapults from his own hands. In terms of ship electric propulsion systems, China is currently at the forefront of the world. China has already adopted medium voltage direct current technology, while the United States is still using medium voltage alternating current technology, lagging behind China by a whole generation.In the future, China will gradually apply all electric propulsion systems to its warships, and in the field of electromagnetic catapults, China is far ahead of the United States. Although the United States has already installed electromagnetic catapults on aircraft carriers, reliability is a major issue. China's electromagnetic catapults are not only several times more reliable than the United States, but also have higher ejection efficiency. In the future, China's Type 003 aircraft carrier will be equipped with electromagnetic catapults.The picture shows Academician Ma WeimingOverall, the scientific research achievements of Academician Ma Weiming have enabled China to completely surpass Europe and America in the fields of naval power and electromagnetic catapult technology. It is believed that Europe and America have imposed a comprehensive technological blockade on China in these technologies. Now, China has not been intimidated by the blockade, but has become a leader. In the future, it will be China's turn to impose a technological blockade on Europe and America.
