Yan Kai, deputy to the National People's Congress and director of the State Key Laboratory of Deep-sea Manned Equipment, said on the 7th that China's 4,500-meter manned submersible will be completed during the 13th Five-Year Plan and completed the sea trial. China will launch the development of a 10,000-meter manned submersible this year.
In an exclusive interview with Xinhua News Agency reporters, Yan Kai said that through the unremitting efforts of the past six years from 2009 to the present, the 4,500-meter manned submersible research team has broken through the development of titanium alloy manned ball shells, the development of ultra-high pressure sea water pumps, and low noise integration. The development of magnetic coupling electric propeller and the development of four key technologies for oil-filled lithium battery, and completed the design and preliminary design of the submersible.
"The independent development of the main system of the submersible is currently underway and is expected to be completed within two or three years. The 4,500-meter manned submersible will be fully applied with localized technology and equipment, fully and comprehensively considering the safety, practicality and economy of the submersible. Sex and maintainability," he said.
Regarding whether China will develop a 10,000-meter manned submersible, Yan Kai said that according to the key research and development plan guide recently released by the Ministry of Science and Technology, the development work will start this year. The relevant units have started the demonstration work of the project and the research work of some technologies.
"A series of technical problems such as materials, structures, communications, and energy that can withstand a water pressure of 11,000 meters need to be solved. If this 10,000-meter manned submersible is successfully developed, Chinese scientists can reach any depth of the world's seabed for scientific investigation and operation. Explore the unknown underwater world." Yan Kai said.
He said that the successful development of the "Jianlong" has a milestone. "More importantly, through the research and development of the 'Jilong', we have trained and trained a team with practical experience to lay a good foundation for the development of high-end deep-sea equipment in the future. basis".
The Science and Technology Innovation 2030-major project proposed in the draft of the 13th Five-Year Plan outlines the Deep Sea Space Station. Yan Kai said that the entire process of dive, work, and float of the "Zhenlong" can last up to 12 hours. The envisaged deep sea space station can operate in a specific sea area for a long time, which may be as long as half a month or longer, and the space is much larger, can accommodate more than ten people, and can carry a series of work submersibles or homework. Tools, such as inspection and maintenance of submarine pipelines and other subsea operations, and are not affected by the bad weather on the sea surface.
“The deep sea space station is an important development direction of deep sea equipment technology, but the technical difficulty is also very large. It is necessary to solve a series of technical problems such as large-scale pressure structure design and processing, release and recovery operation tools, etc.†Yan Kai said.
The draft outline proposes to implement the innovation-driven development strategy. Yan Kai said that as a scientific and technological worker, he is very encouraged. He hopes that the country will build several national laboratories or national technology innovation centers and other innovation platforms in the field of high-end marine equipment, and accumulate a group of outstanding talents. Cooperate in tackling key problems, build an innovative R&D base with world-class level, and lead the development of marine high-end equipment manufacturing industry.
Concerned about surprises
Industrial Park Sound Barrier is mainly used as a noise reduction of road, highway, viaduct and other noise sources. It is a kind of barrier set at the side of road or railway in order to reduce the impact of vehicles' noise on residents nearby.
