After 21 successful breakthrough 4000 m depth, China has independently developed a manned submersible “dragon” was about to redouble their efforts to attack the 5000 m deep. In China people are expected to re-create the miracle of the human exploration of marine occasion, Xinhua News Agency reporter Zhuan Fangliao “dragon” was the chief architect of South Xu dioxin.

Reporter: If the “dragon” was a successful breakthrough in 5000 m depth, it means that China’s deep study of the global scope can cover more than 70% of the ocean. Technically, the “dragon” in the global scale is one of the best of it?

Xu dioxin South: Review of the development of underwater world history, China is the fifth successful deep-sea manned submersibles developed countries. As the law developed scientific equipment, the equipment after the R & D are to be generally more advanced. China has developed a variety of manned submersible technology, resource conditions compared to other countries should be more mature and improve. I can proudly say, “dragon” in the manned submersible in the world, belong to the first tier.

Specifically, the “dragon” was used the most advanced underwater digital communications technology, our system allows water movement “dragon” in the sea to come and go freely. Of course, many of the advanced technology we are developing in other countries on the basis of submersible absorption, improvement comes, can be said to sum up the experience of their predecessors. There are some techniques, such as underwater high-definition video capture and transmission, or the use of temporary foreign products.

Currently, the world powers are submersible underwater to improve their performance or development of the depth of deeper, more powerful submersible, we will continue to “dragon” was the upgrading, while increasing their China’s team in the submerged culture.

Reporter: China’s development and history of deep-sea submersibles less than 30 years, in this short time, we scratch, from weak to strong, come from behind. Our researchers are step by step how to create a miracle of Chinese deep-sea diving?

Xu dioxin South: This course is really hard to describe. Deep-sea submersible, can be divided into underwater robot with a cable (ROV), unmanned autonomous underwater vehicle (AUV) and manned submersibles (HOV) and other categories. China’s underwater, but also step by step, down came to be.

from the 1980s onwards, China began to develop their own early ROV, to 1992 years ago, China’s ROV depth functions are more advanced. And from 1995 to 1998 years ago, China successfully developed the AUV, which is the development of China’s underwater is an important milestone, but also for the development of manned submersibles laid an important foundation.

deep-sea research, and equipment is essential. Back in the 1990s, many researchers have begun to discuss the development of China’s deep-sea manned submersibles the necessity and possibility.

Reporter: The Chinese continue to impact on deep-sea records, the spiritual power behind the miracle is?

Xu dioxin South: Ocean Society Based on years of development work and sea trials, concise spirit of China’s manned deep submergence, and that is: “rigorous truth-seeking, unity, dedication and hard work, scaling the heights.”

each to participate in “dragon” was developed by researchers, players and even ordinary workers, sea trial, these 16 words are used to motivate yourself, selfless struggle, will have a miracle birth of China’s manned deep submergence .

now in the vast ocean above the sea trial team members, they are the real heroes. They are the “dragon” of the birth parents, by their own design, installation of hand, then hand-delivered to the distant Pacific Ocean to test the first time to get first-hand information, but also the first time to improve on the submersible. This line is always standing, professionalism worthy of our fear of dangerous proud.

reporters: “dragon” in the project at the beginning, put the target set in the world the depth of 7,000 meters, which is basically in the global sea unimpeded. What kind of self-confidence and basic, so we set such high goals?

Xu dioxin South: the development of high-tech equipment, the basis of its technological development determines the starting height. “Dragon” in the 2002 project, when we have successfully developed the 6000 m level of the AUV, 3500 m and 4000 m class ROV development work is also in full swing. With high-tech level of support, we do not need to go the old R & D in other countries, the starting point can be set higher. When conditions permit, based on the development by leaps and bounds can be achieved.

the other hand, the use of underwater tasks, the greater the depth, can be more wide range of scientific research. For example, the general distribution of sea ice combustible 2000-3000 m depth, the general distribution of hydrothermal sulfide depth 3000-4000 m, while the manganese nodules and other important mineral resources will have to about 5000 m depth. We are one step, the depth of the submersible research directly to the objectives set at 7,000 meters, in order for the future to provide a wider range of marine survey technology platform support. To sum up, in fact, our idea was very simple. That is: “have the ability, it is necessary on the 7000 meters!”
