dragon 5000 m manned deep diving sea trial successfully

Xinhua Beijing, July 26 (Reporter Rosa Yu Xiaojie) 26, the Chinese” dragon “was the success of manned submersibles the impact of 5000 m deep sea, marine scientific research in China to create a new legend.

successful sea trial on the occasion, deputy director of the State Oceanic Administration, China Ocean Association, the “dragon” was 5000 m sea-level test as the group leader Wang Fei first time accepted the Xinhua News Agency reporter Du Jia interview.

reporters: “dragon” was the breakthrough 5000 meters, what kind of meaning? China’s marine industry mean?

Fei: “dragon” was the break through 5,000 meters, representing China in the field of marine technology as a breakthrough. The successful sea trials, means that we can reach more than 70% of the ocean depths. Ocean accounts for 71% of the earth’s surface, the Pacific Ocean about half of the area, the sea trials for selection in the Northeast Pacific region, compared to 3000 m in the South China Sea for the challenge test more, even greater difficulties.

present, most foreign submersibles in shallow waters in the 5,000 m event, the “dragon” was 5000 m-class sea trials next year will impact the success of the 7000 meters world record test basis.

pregnant with infinite depths of the ocean’s mysteries to explore the ocean, need high-tech means to understand the ocean as a support. “Dragon” was 5000 m sea-level test of the success, the researchers will provide more detailed survey platform for exploring the deep mysteries of science and technology support provides a platform for finding answers to questions of basic science to lay a solid foundation.

Reporter: In your opinion, the “dragon” was a breakthrough 5000 m depth where the difficulty? Our researchers is how to break through these challenges?

Fei: the dive, the pressure and sealing the test deep-sea manned submersibles are the two most important performance indicators. In the water, each additional 10 meters water depth, the pressure will increase to 1 atmosphere. When the “dragon” was submerged 5000 meters, it endured the equivalent of 500 atmospheres of pressure. Equivalent to 1 square meter area on the pressure on the weight of 5,000 tons. Enormous pressure, not only a test of submersible pressure capability, but also a test of its sealing performance.

order to achieve the goal of 5,000 meters submerged in the sea level 3000 meters Test complete return, the “dragon” was carried out some technical improvements. Its operating system, insulation detection system, video system in less than a year to complete the upgrade. Now, the ship length, width and height are 8.2 m, 3.0 m and 3.4 m, empty weight not more than 22 tons of submersibles, have been able to enter the underwater depths of 5,000 meters, and 1 nautical mile per hour speed cruise.

In addition, diving is a submerged body and mind a double test. Vast dark sea, cramped space, cold, damp environment, the unpredictability of the potential risk factors, including people living longer feel depressed, irritable, 5,000 meter-scale experiments, submerged in water 6-8 hours of continuous work, psychological tests can be imagined.

from a technical standpoint, to protect the “dragon” was submerged and security issues, the key is to handle the relationship between weight and buoyancy. To this end, the “dragon” was designed for a variety of security, once an emergency, it can be to carry iron, battery boxes, sample basket are thrown away, if necessary, abandon the robot, “Brokeback” float. Even if the encounter into a mud like the worst case, there are ways to get out, it’s alarm system will transmit to the surface buoy, deep dive test track in time the mother ship rescue.

reporters: “dragon” was next goal?

Fei: Challenges 5000 m depth after the success of the “dragon” was planning to try to choose the sea again, and to sit at the end, some scientific and technological research in the seabed, and further verify the performance of the submersible.

the 5000 m level after successful sea trial, carrying the “dragon” of the “Xiang Yang Hong 09″ boat will return, and for the security guard responsible for the sea trials, the task of “Ocean VI” continues implementation of international submarine in the Pacific ocean investigations.

However, the impact of 5000 m depth, is the “dragon” of the “trial of the test.” Following the 2010 3000 m sea trials after a successful dive to 3759 meters, the past year we have the “dragon” was a series of upgrading of inspection, sea trial’s aim is to identify problems, then the “dragon” was continuous improvement.

submersible dive depth is just a number, although this figure fully tested the performance of underwater vehicles, but only dive to a depth far from the full functionality of the submersible. In the next dive, we are also in the case of conditions of the research work carried out to test various design features.

Reporter: Please tell us about ever since, “Xiang Yang Hong 09″ boat departure, all parties to support the manned deep diving activities.

Fei: “dragon” was the 5000 m level is 863 sea trial to support the project, State Oceanic Administration is organizing department. State Oceanic Administration, “Xiang Yang Hong 09″ boat before departure, the State Oceanic Administration, led many to see the sea trial team, encouraging them to establish confidence in the, and made fervent hope. “Xiang Yang Hong 09 ‘boat 16 to Tatsumi test area, the State Oceanic Administration form the leadership in Beijing via video on the” dragon “was a sea trial team for sympathy. “Dragon” was twice during the dive, the leadership of the Ministry of Science and sea trial unit’s leadership team members and stakeholders are very concerned about the progress of sea trials, a variety of ways to express support for sea trials, and participate in the State Oceanic Administration 24 hours in the sea duty to protect the centers for ground-based testing, sea trials in a timely coordinate and solve problems.

recall the witness, “dragon” was a breakthrough 5000 m depth of the moment, my heart can not be said that both the nervous tension. That tension, because a significant breakthrough in 5,000 meters, is from the marine scientific and technological development of China’s strong pride. Say nervous, because I always our team of researchers and sea trials have firm confidence.

must be stressed that, for marine scientific research equipment is able to work is the most fundamental. Ye Hao 5000 m, 7000 m Ye Hao, but the “dragon” was in the development of one deep footprints. The “dragon” was such a marine high-tech equipment, our goal is “necessary to get deep under, but also put to good use”, so as to truly deep-sea exploration and research services.
