Xu Qinan tells&ldquo ;Dragon &rdquo ;story ( China Science newspaper picture ) in June 3, 2012, Jiangyin South of Jiangsu international terminals .A long whistle in the air ,carrying the &ldquo &rdquo ;dragon ;manned submersibles Xiangyang red 09&rdquo ;&ldquo ;ship away from the wharf ,96 ginseng try personnel ashore and waving goodbye .
Following the 1000 meters ,3000 meters and 5000 meters of sea trial, the ocean survey ship going to exploit the bowels of the earth to the southern end of the Mariana Trench ,China first manned deep 7000 meters sea trial challenge .
&ldquo ;test will face a maximum design depth, challenge and difficulty are great, because this is our first manned deep 7000 meters sea trial .But we have made full preparation .&rdquo ;&ldquo ;&rdquo dragon ;chief designer Xu Qinan said .
Some people say ,his life height ,can be used almost Chinese bathyscaphe dive depth measured .300 meters ,600 meters ,hollister
,1000 meters ,3000 meters ,5000 meters ,7000 meters !Can say ,China Manned Submersible every step of his outstanding contribution ,his dream with submersible dive deeply into deeper waters .
The world can have many such heavy life ,abercrombie
?From the young boy ,to the hair dyeing cream, from the ordinary ship service soldiers to world-class manned submersible &ldquo dragon &rdquo ;number ;the total stylist ,Xu Qi throughout the south throughout the life of the line only a &mdash ;&mdash ;deep submergence !Let our country submersible dive in the sea ,to enjoy the mysterious submarine picture ,to explore the inexhaustible undersea treasure ,hollister
With the dream of powerful nation ,the patriotic enthusiasm for &ldquo ;to fight against imperialist aggression ,we must build a powerful navy !&rdquo ;when Chairman Mao in inspecting naval forces ,Navy wrote exciting inscription .
In this period ,at the age of 17, Xu Qinan was admitted to the Shanghai Jiao Tong University &ldquo &rdquo &mdash ;popular professional ;;&mdash ;shipbuilding system .In the country grew up in Xu Qinan ,and his contemporaries, the heart is filled with a great power dream .
An aircraft ,tanks ,warships ,at a time when many young people is ideal ,Xu Qinan is no exception .In 1956, when he was elected to the national first batch for future naval research and training design staff ,he knew that ,this life will and ships ,and the sea is not divided .
In 1958, Xu Qinan graduates assigned to the marine research institute .He graduated from design to do is &ldquo &rdquo ;surface ship ;,because the job needs ,he was assigned to submarine model hydrodynamic experiments .
About this, Xu Qinan from water into &ldquo ;&rdquo ;under water .But Xu Qinan had never seen a real submarine ,he all about submarine knowledge is derived from books ,hollister france
.At this time, requirements of national cadre of company a ,then ,he volunteered to go to Qingdao ,the submarine base .
At the submarine base ,Xu Qinan first job was &ldquo ;ship service soldier &rdquo ;,is the daily work of the submarine several valve tube and a water pump .The rest of the time ,he did not idle ,with the consent of the submarine captain ,running back and forth ,the submarine was felt pat each cabin .
A month went by quickly ,in order to further study the submarine knowledge ,he was asked to several other submarine and submarine repair factory internship .A total of three months, now in retrospect ,Xu Qinan still feels it is his life a very important time :&ldquo ;I know I what ,how to do ,without even looking at the drawings of the feeling is not the same .
&rdquo ;since then, Xu Qinan has wanted to make the world advanced manned submersible, for our country to open up a broader field of ocean expedition .After returning from the submarine base ,a &ldquo ;presided over the deep ocean simulation equipment and systems ( referred to as the pressure tube equipment ) designed and built &rdquo ,jordan
;task ,to fall on Xu Qinan .
This equipment is mainly used in the laboratory to establish simulated deep-sea enormous pressure of environment ,to test various underwater pressure structure and equipment bearing capacity and its seal, which is the submarine pressure hull structure strength and stability design of essential experimental equipment, while abroad on China is the implementation of strict technical blockade .
By virtue of papers on American Naval Research Laboratory of a photo, Xu Qinan and project members rack one ,in the processing factory technical staff and worker support, in 3 years time ,has developed the first domestic international is advanced at that time structure form the card ring seal pressure cylinder device .
Nineteen seventies ,he puts forward the double shell ,hollister
,fixed ratio pressure new structural form ,and built the largest pressure cylinder device and system &mdash ;&mdash ;the pressure up to 25 MPa ,3.
2 meters in diameter ,9 meters high ,this series of pressure cylinder group for China ship and submersible structure research laid on base .&ldquo ;thanks for that era ,hollister
.&rdquo ;Xu Qinan said ,the new Chinese submarine to be poor and blank start on the foundation ,from scratch ,from weak to strong ,he participated in the cylindrical pressure hull structure design of introduction ,digestion ,copy the whole development process .
From the train traffic control, to the equipment installation ,hollister france
,to experiment ,to write analysis report ,along the way, he became the versatile &rdquo &ldquo ;.People honed in on always can grow very fast ,in the process of practice ,he laid a solid foundation ,and gradually formed its own innovative ideas .
Open division career ,create brilliant career in 80 s of last century ,with the development of Ocean Engineering in China ,the vehicle needs more and more pressing ,Xu Qinan has served as the four submarine chief designer ,creative development of a number of manned submersibles and underwater robot .
Working depth of 300 meters ,600 meters by 1000 meters to 6000 meters ,7000 meters ,;type manned ,unmanned ,cable ,cable ;the control method by manned manual ,with cable remote control ,to the development of intelligent control .
At the beginning of the 80 ,Xu Qinan as chief designer ,lead ship heavy industry group seven two 5 units such as Institute of technology backbone ,the successful completion of the first single atmospheric diving device and double function atmospheric diving device development ,reached the international advanced level of similar products ,to fill the domestic blank .
At the end of the 80 ,Xu Qinan as the ship company appointed chief designer ,put forward to catch up with the advanced international level with optical fiber communication cable controlled underwater robot design scheme and technical route ,which is mainly considered to rescue ,marine oil and gas development of high-power operation type cable controlled unmanned submersible .
In the early 90, Xu Qi South served as China self-developed large depth intelligent underwater robot Explorer &ldquo ;&rdquo ;number of deputy general designer ,to enrich the experience of successful completion of the project and design of carrier system .
On 1992, Xu Qinan also served as the 6000 meters of autonomous underwater vehicle chief designer ,this is the current international advanced high-tech level of reflection ,it can reach the earth in 94% areas of .
Nobody ,manned ,cable ,wireless &hellip ;&hellip ;&ldquo ;Xu Qinan said :almost all kinds of submersible, I have done .&rdquo ;and his only disappointment is ,did not have the opportunity to complete large deep manned submersible .
In fact ,since the late last century ,abercrombie france
,along with the human resource consumption demand grow with each passing day ,countries are increasingly paying attention to the boundless ocean .Deep sea technology is thought to be related to aerospace technology ,nuclear energy utilization technology of high-tech fields, and manned submersible is ocean development and ocean at the forefront of technological development and the commanding elevation .
In 1992, Xu Qinan China ship heavy industry group seven two Institute to the State Science and Technology Commission (now the Ministry of science and Technology ) developed 6000 meters deep manned submersible suggestion .
However ,due to the limited conditions, application has been approved .In 1996, with regret, sixty years of age of Xu Qinan through retire formalities ,he thought his life struggle dreams thus shelved .
However ,that often appear in the corner .He never thought of ,a few years later ,he set out again ,in the Times wrote about the deep legend ,the achievements of the cause of depth and high life to &hellip ;&hellip ;picked up yesterday dream ,ready to start the new century bell had just sounded ,in China the association organization, domestic science and marine sector 10 academicians and 15 a professor of experts and the national development and Reform Commission ,Ministry of finance ,Ministry of science and technology ,Ministry of foreign affairs about leadership are discussed ,finally reached the R & D of manned submersible consensus .
In the project before the election, general designer ,we all thought of Xu Qinan ,&ldquo ;he is the right person for &rdquo division ;.But when he was 66 &mdash ;&mdash ;according to the national &ldquo ;863&rdquo ;major special general designer ,division of age should not be more than 55 years ,the Ministry of science and technology for he break precedent .
Late one night in 2002 June ,mulberry
,Xu Qi south to 702 former director Wu Yousheng academician phone :&ldquo ;7000 meters of manned deep submersibles project ,we think it over and over again ,the division of your old Xu when not !&rdquo ;put the phone down after Xu Qinan heartbeat .
Submersible, in Xu Qinan ,is never love a lot, especially the 7000 meters of manned deep submersibles ,is he for many years .However ,the family did not agree with :because he is suffering from heart disease ,hypertension ,one eye has been the only light .
In the 6000 metre autonomous underwater robot sea trials back ,heart beat ten thousand times a day to &mdash ;&mdash ;the rest of the time, but also how to do the work so hard ?Xu Qinan said :&ldquo ;I think a submarine ,the head is not painful, not thinking is the pain .
Or to take the task ,make me feel comfortable .&rdquo ;finally ,he is nearly nine years old and his mother agreed :&ldquo ;you do it !Do you .&rdquo ;2002 June, Ministry of science and technology formally to 7000 meters of manned deep submersibles as &ldquo ;863&rdquo ;&ldquo ;fifteen &rdquo ;during major projects in China ,this started a deep technology in the field of battle of assault fortified positions .
This was later to be named the &ldquo &rdquo ;dragon ;number 7000 meters deep manned submersible .With responsibility, with hope ,picked up once stranded dream ,the 66 year old packed up and start again ,toward the sea .
&ldquo ;he is like my child ,I watched him grow up day by day .&rdquo ;Xu Qinan said .Assembly completion after the initiation of tank test .In more than half a year time, it undergoes equivalent deck laying ,surface inspection ,dive ,cruise ,sit bottom operation ,rise ,the whole process of debugging and recall deck pool inside the emergency buoy release test .
In March 2, 2008, the manned submersible through the National Oceanic Bureau organized the test to confirm .Since then ,it has a famous name &mdash ;&mdash ;dragon .Witness the dream life ,measuring depth of witness of the realization of dreams, is undoubtedly the most exciting things .
In 2009, &ldquo &rdquo ;dragon ;first sea trial ,74 year old Xu Qinan insisted and everyone aboard the &ldquo Xiangyanghong 9 &rdquo ;.He said :&ldquo ;strictly speaking ,the division is a must on submersible dive ,all in order to take care of my body ,I have no responsibility .
;he was getting into the boat ,with brightly coloured drugs and oxygen machine ,blood pressure and other necessary equipment filled with a rod boxes ,medicine is like eating &rdquo &ldquo ;.
Even so ,in two months in the sea, Xu Qinan but was compelled by illness to shore to rest for 10 days ,the time and young people, adhere to the ship .During the two months of the test site, everywhere has the figure of Xu Qinan .
He goes to the rear deck viewing device ,to guide the work ,to the back of the plane and the exchange of technical personnel ,to analyse and discuss the submersible ,technical details, returns to the room, the static under heart to submersible test each step are batted .
Before the test ,after the test of key operation positions to bid and ask ,do not let off any possible risks .Each submersible water, he never sat back in the control room ,but for a few hours on duty in the control room ,sparing underwater acoustic communication back every word speech &mdash ;&mdash ;although the sea for hours ,back to the mother ship voice but ten sentences ,but he is a rather than miss .
Be strict in one Xu Qinan working style and working enthusiasm infected every participating member .He is a submersible sea test of the soul, he will feel at ease ,sureness ,test team .
Under his leadership ,all participants to maintain good mental state ,created at that time China manned diving record for the 1109 metres ,the successful completion of the test task .In fact ,in this 10 years, and he as the shadow follows the form the &ldquo dragon &rdquo ;number ;besides, there are full of pain .
His right eye retina has come off ,left eye sight is not good ,go particularly close ,to see who one is ,and the familiar greeting people rely on identifying contours .He almost every year we have a heart attack ,became a frequent visitor to the hospital .
Each hospital ,doctor asked him to stay a minimum of two weeks ,but a better he sits still ,often time to &ldquo &rdquo ;escape ;hospital &hellip ;&hellip ;because his mind filled with is always the &ldquo dragon &rdquo ;!In 2010, &ldquo &rdquo ;dragon ;second sea trial ,shock 3000 metres .
Because advanced in age ,physical discomfort ,long-distance voyage ,Xu Qinan failed to board, but he still worried about ,still braved the intense heat of summer, adhere to a base in Sanya for a month and a half ,full participation in the manned submersible 3000 meters sea trial .
In 2011, &ldquo &rdquo ;dragon ;third sea trial ,shock 5000 metres .This time ,he wanted to sail ,to &ldquo &rdquo ;dragon ;latent sea duty on deck .However ,his heart disease heart has not allowed him to ocean voyage .
He can only observe the broadcast before the big screen, each receiving ship colleagues email message ,with their own unique way to accompany themselves with &ldquo dragon &rdquo ;number .
Every dive ,for &ldquo ;on &rdquo dragon ;bring a technology innovation .From 50 meters to 1000 meters ,from 3000 meters to 5000 meters ,it is this a sea trial success ,declared China deep level entered the ranks of the advanced countries in the world .
Leading the near bottom automatic navigation ,hover position ,high-speed underwater acoustic communication and other functions ,is to let the Chinese dragon &ldquo ;&rdquo ;ride the wind and waves ,in deep sea .
Xu Qinan said ,he is lucky ,&ldquo ;once thought that this life this fail to realize its dream ,but now he got such good results ,I have no regrets !&rdquo ;&ldquo ;&rdquo nowadays ,dragon ;number set sail once again ,to 7000 meters deep-sea diving .
This is &ldquo &rdquo ;dragon ;the depth ,but also the spirit of Xu Qinan depth ,depth of life &hellip ;&hellip ;Xu Qinan &ldquo &rdquo academic card ;dragon ;chief designer ,our deep technology pioneer and one of the leading experts .
In 1958 graduated from the Shanghai Jiao Tong University Department of naval architecture ,after graduation to join the submarine structure research and marine equipment industry ,serving as the four underwater vehicle chief designer .
As chief designer ,Xu Qinan creatively developed a manned submersible and underwater robot .Working depth of 300 meters ,600 meters by 1000 meters to 6000 meters ,7000 meters ,;type manned ,unmanned ,cable ,abercrombie france
,cable ;the control method have manned manual ,with cable remote control ,intelligent control .
Manned submersible is China single atmospheric diving device ( QSZ- Ⅰ ),dual function atmospheric diving device ( QSZ- Ⅱ ),underwater robots are heavy cable controlled unmanned submersible ( 8A4 underwater robot ) ,6000 meters of autonomous underwater vehicle ( CR-01 ) ,also as deputy general designer to finish 1000 m autonomous underwater vehicle ( &ldquo ;&rdquo on development of explorer ;) .
