In the 47 days for a test mission, below flood dragon ", "will carry out four times to descend. 21, execution is first to descend. The second descend, will impact 5000 meters deep sea. Why is 5000 m? "If the sea try, success means our manned deep level reached the advanced world level." China ocean association secretary-general, manned the leading group JinJianCai try deputy chief said, although the United States, France, Russia, Japan four countries are now available to descend 6000 meters and even 6500 m manned submersible ware, but at present the diving depth in often within 5000 metres. Because to get 5000 m depth, can get around the earth's oceans in accounting for 75% of the area of the bottom.
July 1,, our country the first morning his own design, integrated platform independent of the dragon ", "manned submersibles set sail from the jiangyin, jiangsu. The future 47 days, it will sail to the northeast of 5000 meters, is the sea level try.
For "flood dragon" number, 5000 m just a semicolon, it really want is 7000 meters of the depths of the sea. "2012," dragon ", will challenge 7000 m world depth." "The flood dragon" chief designer, xu south in the works when accepting a reporter to interview the depth of 7000 meters, said accounted for 99.8% of the area of the earth's oceans, this means that our country submersibles can be in accounting for 99.8% of the world's vast sea freedom of action. "The sea bed is substantial resources to be developed, sea creatures, the ocean chemical, Marine earthquake and the further development of discipline, need such powerful tools."
In this year's deep test, "flood dragon", 5000 meters deep impact success, it will be the biggest manned submersibles descend a depth of 7000 meters lay the foundation. And it will carry out the photography, video, bottom topography measurement, Marine environment parameters measurement of homework test and application.
"Side, the side improve experiment, the side to improve." Xu said, deep south works, is currently the biggest test or from the pressure. He made a comparison: the 7000 metres of water pressure energy equivalent to 700 kg weight will be in a little thumb a size of the cover. Face the pressure, 7000 meters to the computer chip, this kind of can't withstand the pressure components, need to have pressure pipe to protect. To some, like battery box such structure, this is through an oil filled compensation methods, to pressure inside and outside pressure balance, and to minimize box wall thickness, to reduce the weight of the body, still can increase oil medium insulation protection ability.
"A scuba diving is sure enough, and further developed in, we also continue to improve reliability, d sex, GuoChanLv, and to reduce the operating cost." 7000 meters deep and not by our ultimate goal, design, manufacture of deep manned submersibles, will be in human resources development and utilization of the ocean of recognitions.
The Wall Street journal published on July 20, entitled "China is pounced on deep sea treasure" article said that China is in the Pacific Ocean in plans or to develop the world's oceans in the underlying mineral resources in the United States and China, beyond speculation "dragon's deep sea exploration" another figure ", or existence has military significance.
