Dragon challenge to the Pacific, descend 7000 meters may record
Widely nets jiangyin June 3, Cheap ray bans news (reporter ZhouWenChao) according to the sound of China "news and vertical and horizontal" report, today (3) morning, "xiangyang red 09" test mother ships will launch flood dragon manned submersibles jiangyin southern jiangsu international terminal from set sail, and rushed to the marianas trench regional executive flood dragon manned submersibles 7000 meters sea level test tasks, from eighteen domestic units of 96 players will challenge the China manned tested the new record in history.
Flood dragon, to challenge this Pacific descend 7000 meters
China is the United States, France, Russia, Japan in the world after the fifth master deep manned deep technology country. If the flood dragon manned submersibles 7000 meters sea level try success, will likely to create the world of homework for manned submersible maximum depth of diving.
Contain flood dragon, to the curious, routed the reporter comes to southern jiangsu international terminal beitou. Parked in the docks of xiangyang red 09 YiBo ongoing. And in the end of the ship deck, the flood dragon, submersibles stop lying in a steel shelves quietly. The first two days, and it has just undergone first rally rehearsal, were two times into the water. TangJiaLing when out of the capsule silent hunter member, said the potential of the tank, and other facilities operation life in good condition.
A close look, dragon, discover the eight meters in length, width 3 meters, 3 m high more submersibles appear a little chubby. The body of the white, red tail, printed on "863" special and China association of the logo. In its first minister many feet, careful about just know is the underwater lamp and camera equipment.
The high pressure and low temperature descend face challenges, etc
"The flood dragon" manned submersibles total designer xu pumps dioxins south said, "dragon", late June in west Pacific mariana trench Micronesia waters near 7000 meters level manned deep-sea diving experiment, the test will be faced with the maximum design water depth, high pressure, low temperature and challenges.
Xu pumps dioxins south: 7000 meters to the Marine environment is the main characteristic of the water under a lot of pressure. From 5000 m to 7000 m will send 2000 meters, give a simple example, we used to use floor area, descend 5000 meters, every square metre 5000 tons of pressure to bear, descend 7000 meters, a square meters will withstand 7000 tons of water pressure, so first face pressure test. In addition, the condition is severe water temperature, cheap ray ban sungalsses descend 5000 meters only 2 degrees around, the 7000 m in 1.5 to 1 degrees that range, and faced with new challenges.
"The dragon," deputy chief designer CuiWeiCheng further analysis in the high pressure low temperature, the flood dragon, face of the three major technical problems.
CuiWeiCheng: first is the seal performance, will not have leakage; Second, under high pressure may have different degree of deformation, cause a short-circuit. Third, there are many submersibles oil filled equipment, hydraulic pressure system, the oil in the high pressure under low temperature performance how to, through the experiment proved that.
Improve hydraulic system, high definition video system
And last year, the dragon has 5000 meters compared scuba diving, xu pumps dioxins south said, this time, the dragon in hydraulic system, high definition video system are improved.
Xu pumps dioxins south: improve the hydraulic system, makes the hydraulic system can improve the depth of so much pressure and low temperature adaptability; Improve the hd video system, according to the experience of the last year, we head to flood dragon, sixteen underwater lamp to made a layout, the area of illuminate of makes it more reasonable. At the same time, to hd video information transmission capacity strengthening, so can make in underwater get the image clearer, colour is more realistic. Third, with a GPS positioning device, ensure submersibles complete underwater operations of the sea to return to, the rules on the bad weather, can in the shortest time, the fastest speed, to make the diving the exact location, to increase the safety of diving.
