Jiaolong will sail for the Southwest Indian Ocean in November this year

    On October 23, at the 11th Dalian International Maritime Exhibition, Xu Mingnan, a famous expert in the field of deep submersible technology, chief designer of Jiaolong and academician of Chinese Academy of Engineering, was interviewed by the newspaper. He disclosed that in November this year, Jiaolong will go to the polymetallic sulphide sea area of the southwest Indian Ocean after the overhaul, and "will come back after the Spring Festival".

The father of Jiaolong and Jiaolong both live in Wuxi.

Yesterday, Dalian International Maritime Exhibition held the Forum on Marine and Ship Science and Technology. Many people came to the forum to see Xu Junnan, 78-year-old academician of the Chinese Academy of Engineering and father of Jiaolong. When Xu Zhenan, a silver-haired man in suit and leather, stepped onto the stage, there was applause from the audience.

Xu Junnan, a native of Zhejiang Province, currently lives in Wuxi, Jiangsu Province, because Jiaolong's production and maintenance base is in Wuxi.

In an interview, Xu Junnan told reporters that Jiaolong, with a maximum submergence depth of 7062.68 meters in 2012 (theoretically covering 99.8% of the world's ocean area), had just completed 10 experimental submergence operations in the Northwest Pacific and the Western Pacific this year, and had completed a survey of local topography, landform and biodiversity characteristics. After the return voyage, Jiaolong returned to Wuxi base for comprehensive data analysis and maintenance. During this period, Xu Gennan has been leading the deep diving team of China Shipping Heavy Industry 702 Research Institute to work for Jiaolong. "Every 1000 meters of submersible is equivalent to 100 atmospheric pressure. As Jiaolong, which is very close to the level of the United States, its deep diving team is facing unprecedented difficulties at all times. Xu Gennan said. He told reporters: "At present, the main force of the team is mostly young people in their 30s and 40s. Jiaolonghao not only contributes to the national scientific research, but also contributes to the national talent training."

Jiaolong's First Unmanned Submarine Operation

After finishing the renovation in Wuxi, the Jiaolong will go to the southwest Indian Ocean in November this year. "I will work in the Indian Ocean for three to four months before I come back after the Spring Festival. Next year, Jiaolong will have two big tasks to accomplish. Xu Gennan said.

Xu revealed that Jiaolong was the first to carry an unmanned submarine for joint submarine operations in 10 dives in the Northwest Pacific and Western Pacific this year. The small remote-controlled submersible was named Dragon Ball. "Dragon Ball" was tested at a depth of 2800 meters, and "Dragon Ball" also shot a video for Jiaolong. In November this year, the Jiaolong will travel to the southwest Indian Ocean, and the Dragon Ball will probably follow her.

As for the upcoming journey in November, Xu said, "The difficulty of this expedition may be greater than before. The sea temperature in the southwestern Indian Ocean is too high. There will be high temperature liquid gushing out from some geological areas at 2300 degrees Celsius, so we will have some technical countermeasures."

"Twelve scientists participated in Jiaolong's 10 experimental dives this year, and two were female scientists," Xu said. At present, Jiaolong is quietly staying in a huge workshop in Wuxi, his hometown. For the November journey, Jiaolong is making final preparations.

Dialogue between Jiaolong and Shenzhou IX "Haitian" Dalian had technical support

On June 24, 2012, a world-renowned dialogue across the sea and sky was held between Jiaolong and Shenzhou 9. Yesterday afternoon, Xu Junnan, the father of the Jiaolong, played the farthest dialogue between human beings again, and the clear voice resonated. Most people do not know that this sea-sky dialogue has the indirect help of Dalian's research results.

Yesterday afternoon, at the forum of the 11th China Dalian International Maritime Exhibition, Xu Junnan, chief designer of Jiaolong, whose theme was Jiaolong Deep Submersible and Its Application, broadcast such an audio. On June 24, 2012, a new record of manned space flight and manned deep diving was born in one day in China. At 1741 hours on the same day, Shenzhou 9 astronauts Jing Haipeng, Liu Wang and Liu Yang, who successfully completed the manual rendezvous and docking mission, congratulated and greeted the three submariners who had set a new record of 7,000 metres manned deep diving in China. Jing Haipeng, on behalf of Shenzhou 9 flight crew, said: "Today, when we successfully complete the manual rendezvous and docking mission, Xiwen Jiaolong has created a new record of manned deep diving in China. He pays high tribute to Ye Cong, Liu Kaizhou and Yang Bo, and wishes China a new and greater success in manned deep diving. I wish our motherland prosperity and prosperity." Previously, the Jiaolong submarine sent his best wishes to Shenzhou 9 at the bottom of the sea: "I wish the three astronauts, Haipeng, Liu Wang and Liu Yang, a successful docking with Tiangong 1. I wish our country a glorious success in manned space flight and manned deep-seated undertaking.

When these two clear voices were broadcast on the forum, the audience applauded. Yesterday afternoon, academician Xu Gennan, who just finished his speech, told us in an interview with our newspaper that the voice of the dialogue across the sea and sky was so clear that it was inseparable from the high-tech acoustic technology used on the Jiaolong. "Jiaolong's work on acoustic equipment has some technical connections with Dalian." Xu Junnan said. From Xinhua.com
