Recently, the national key research and development plan "Deep Sea Key Technologies and Equipment" key project, the domestic 4,500-meter manned submersible, after 48 hours of transportation, met smoothly with the "Exploration No. 1" working mother ship at the Winchong dock in Guangdong. After that, a series of installation, commissioning and inspections will be carried out at the terminal. After the various acceptances have passed, the submersible will conduct sea trial work. Ye Cong, the deputy chief designer of the submersible, said that the real working environment from the pool to the mother ship is a process that needs to be adapted and adapted to the submersible.
So what are the advantages of the 44,500-meter manned submersible compared with the "Zhenlong" that China has successfully developed?
The first increase in localization rate
In terms of appearance, the "Jilong" and the 4500m manned submersible are not much different, but according to experts, many parts of the "Jilong" are imported, and this time China independently developed the 4500m manned submersible. The localization rate of core components has exceeded 90%, and the yield of component countries has increased significantly.
The second performance is greatly improved compared to the "Jilong"
In terms of performance, the 4,500-meter manned submersible developed this time is also significantly improved than the previous "Jilong". For example, the manned cabin of the 4500-meter manned submersible has five observation windows, which is two more than the “Jilong†and has a better view on the seabed. In addition, the 4,500-meter manned submersible replaces the original silver-zinc with a lithium battery. The number of batteries and batteries available has also increased from 50 to 500.
The third is to pave the way for 10,000 meters of submersibles
In addition, not only is the localization rate increasing, but more importantly, the current 4,500-meter manned submersible is like a bridge connecting our “Jilong†and the future 10,000-meter manned submersible. Through this submersible, the reserve power of China’s manned dive has been cultivated.
Chief designer Hu Zhen said that the deepest place in the world at the bottom of Shanghai is more than 10,000 meters deep. The detection capability of the new manned submersible of 4500 meters is not the ultimate goal of China's independent development. On the basis of 4,500 meters, there will be more expectations for the future of China's manned dive. Hu Zhen also said that at present, China has deployed a project with a depth of 11,000 meters, and now it is starting research and development, and it is expected to launch in 2020.
