Autumn 2009, the People’s Navy submarine force came good news: China has independently developed the successful completion of a new type of submarine dive limit, underwater high-speed, deep-sea mine warfare launched series of tests and training evaluation, etc., all the performance indicators to meet the design and operational requirements, marks the formation of China’s new submarine fully operational capability.
The birth of a new submarine, the Navy’s rally in a factory representative of the military effort and sweat. Them, with the basing of the Republic of loyalty and blood iron and steel “Blue Whale”, from the slipway towards the ocean.
Mission: To the birth of a new submarine, the new starting line sprint
One day in December 2006, the CPC Central Committee General Secretary and State President and CMC Chairman Hu Jintao, himself for a new type of submarine in the first boat out into the flag.
After the flag presentation ceremony, Hu Jintao has boarded two new submarines to inspect deep into a battle for every bit, asked in detail about the quality and performance of equipment, he repeatedly advised the boats the men, we must learn the proper management and use of new equipment, so that new equipment combat as soon as possible.
Turn of the century, after the CPC Central Committee, Central Military Commission, China formally started the construction of new submarines.
The development of new submarines, the People’s Navy an important step in restructuring and development.
History has chosen them – the Navy Military Representative Office in a factory to assume supervision of the sacred mission of the new submarine.
New submarine must be high-tech age births. The need to re-establish production lines, processes, equipment, materials need to re-develop, staff need to re-train … … all stand in a brand new starting line.
Similarly, the military representatives stationed in a factory room will also be standing at a new starting line. From more than 10 local colleges and universities by the army and assigned to the representative chamber 40 doctoral, master’s and undergraduate students, embarked on a new type of submarine supervision positions.
The face of new submarine involved in more than 1,000 professional and technical categories, the young delegates to a military fort launched a dash of technology: “brush up” professional knowledge and 10 days won a major; familiar with drawing information, they often all night long and his eyes bloodshot; to master technical personnel and workers ask for help, plant three shifts, they Lian Zhouzhuan … … In this way, a new generation of military representatives in just 3 months into his new role on the half year to assume supervision of the independent task.
Chinese New Year has just passed, the new submarine power component installation is in progress.
Conductor gallery filled with relevant leaders and experts, through the video system, they watch every detail of installed components.
Article 10 components begin filling.
Designers, on-site construction and assembly plants have confirmed that the professional inspector: fuel assembly number, coordinates and drawing on the logo exactly the same.
As a member of the Group 3 tests, 25-year-old was alone in the military on behalf of Liu Haipeng stayed. He repeatedly warned myself: careful, careful, and then carefully!
Power Components Up to dozens of groups, internal structure, composition different from the appearance it is difficult to distinguish. Liu Haipeng Projections by the Working Principle: “10 components should not be in this position!”
On-site commander immediately ordered: operation suspended! Liu Haipeng than made after repeated: “Drawings identification error!” Authorities immediately organized the right drawing, component, loading position re-examined to confirm the conclusion that: “Liu representative was right!”
The chief architect of the new submarine the first time that this has happened, immediately called to the scene: “a young army representatives to find such an important issue, great!” Liu Haipeng awarded for this second-class power.
Submarine construction is a large and complex systems engineering. Military representative to bear from design to construction, the whole process of inspection and acceptance testing.
Fan-Ming Meng, Deputy Chief Representative briefed reporters on such a string of numbers: a new type of submarine construction from start to delivery units, the military need for the identification of projects on behalf of more than 100,000, and acceptance of technical documentation, drawings data, calculated data can be loaded with a truck .
On behalf of the whole group of seven military to check the acceptance of the project reached 1.5 million, related to the overall layout, shipping performance, hull structure, outfitting anti-corrosion, vibration and noise reduction five major professional 50 subjects; wheel unit 9 comrades in charge of 66 large systems, 732 sets of equipment; Wubei Group of electronic equipment must correspond to only a few dozen factories … …
Wu Wang Yang, 23-year-old military representative on the task of independently undertake the submarine acceptance. In September 2008, he was at the construction site supervision, “the external branch of the cartridge loop” machining, through measurements found that workers crossed position will be processing classified high. In case processing is wrong, will affect the missile launch tube of the benchmark, we should scrap the whole cartridge will bring about a series of serious consequences. The discovery of a timely, Wu ocean by the award.
Cross: In order new submarine high-performance, the face of risk is not made to give up
Represents a new type of submarine of modern science and technology and industrial development in China, the highest level achieved “From there to the superior” historic leap:
Widespread adoption of new technologies, new processes, new materials, new equipment, system is more complete, more advanced performance, operational faster reaction, and quiet performance, better and more offensive capability.
Military representatives of the leader to lead the cross.
New type of submarine tonnage big, large diameter submerged deep, deep need to adopt to withstand the pressure of new high-strength steel.
We all eyes are focused on the success of our newly developed special steel. Stretching, bending, cracking test; hardness, precision, density testing; fracture inspection, chemical analysis … …
However, it is troublesome is: precisely because of this high-strength steel “rather break than bend” and “steel” of welding very difficult.
The first welding test, examination pass rate for less than 10%!
The second, third … … have several tests, pass rate has hovered at a low level. The new submarine welding pass rate requirement to be 100%!
Problem repeatedly attack high, so that everyone felt the high-strength steel using this great risk, hastily adopted, if the weld was defective, the consequences can not imagine. “Otherwise in the end use of this steel?”
Military representatives and the builders of these concerted efforts: “high-strength steel will never give up! The key technology is not a breakthrough, submarines, it would not be ‘for type’, the follow-up boats also will be affected!”
Military Representative Office, together with the factory specialized research project and began the difficult process step by step to explore.
The whole factory selected 80 welder training, on the model tests carried out under harsh conditions. Beginning of winter frost winter, temperatures dropped to minus 20 degrees Celsius, the military brass bridge on behalf of Lee, Chen Ai-Zhi, Sun Qian, Li Ning, Zhang W, Fan name of qi, and the workers work alongside the master, facing intense welding arc welding to do test burns of the eyes, swollen cheeks frozen, and rotten cold toes, and may be their determination than high-strength steel is also hard.
Welding wire, gas, process overall innovation. From the soft and hard wire, gas ratio, welding speed to weld parts of the “warm” “After the heat,” from hand-welded to the automatic welding, work hard for 37 days, after hundreds of failures, they finally find out about the high-strength steel The “temperament,” a key breakthrough in welding technology, and achieve process stability. The range of advanced surface by means of weld testing and internal testing, with a pass rate of 100%!
The development of new submarine in the construction process, the military representatives participated in 100 research a number of major technical problems in the field of more than 10 core technologies to achieve a major breakthrough and make it applied.
This year in August, the new submarine boat on land the first joint test. Boats followed the “rotating main converter unit,” is to ensure the safety of the submarine core equipment. The FBI found that the equipment characteristics of instability, and can not be used in emergency state manual. As a test head of the military representatives Pei Feng insisted that: The new boat for the first time power system automation control, must also guarantee that an emergency start. Focus on the need for new submarines, he strongly advocated a more advanced “static-type main converter devices.”
This, at that time was a “world problem.” Representative Office in the military leadership’s support, Pei Feng took part in the research team, after hundreds of day and night research, and finally successfully developed the “static-type main converter device”, this new equipment to enable a new emergency power system, advanced submarines, reliability increased dramatically.
A truly new type of submarine is a submarine information. Electronic equipment Mimizaza, performance, complicated. Military Representative Office of the lead set up the “expert group” for the various kinds of electronic equipment on the boat to simulate the magnetic field testing, the establishment of electromagnetic radiation “ultra-poor assessment of the” new models and to analyze the surrounding equipment, anti-jamming capability. Through calculation and test, design the ideal information equipment compatible programs, the implementation of equipment, systems, the overall three control and successfully resolved the high-tech brings new risks, to ensure that a new type of submarine information superiority and comprehensive operational effectiveness of the play.
Responsibility: sign acceptance on behalf of the State, depending on the quality of the submarine, such as life -
Chief representative of the CHAI Xiao-wen, in the submarine supervision post for 20 years, participated in the development of China’s first generation of submarines supervision, supervision of new submarines is now a leading figure. He knows the military on behalf of the inspection report, signed on the weight put pen to paper: “We are representing the State Inspection and Acceptance.”
Quality is the life of the submarine, but also on behalf of the military life. The birth of each submarine, from a steel plate, a weld, a valve, a bolt, the military representatives have to personally pass three hurdles, let off a shred of vulnerability.
“Crawl space” is the military representatives of the “basic skills.” Submarines, hundreds of small compartments, each bilge corner Sazhuo their sweat.
“More difficult to drill areas, the more ‘technology accessibility’ test priorities.” Overall team leader Li Ning deliberately explained: not “drill” but “climb” and must “limbs touch the ground.” Double pressure shell caught, followed by almost a drawer, only flat tummy in, pour tummy out, get out of being stuck in the inside is a frequent occurrence. Time, the military on behalf of Zhang to 9:00 crawl out until 15 o’clock, because collapse was almost choking, dragged out, arms, knees are frayed leather … …
Ning rough forget this: 1 boat dry down, the military stands for “crawl space” total length of more than 400 kilometers, the equivalent of 10 marathons crawl forward!
“Submarine is no small matter.” The smallest details have contests. On one occasion, the shipyard, “complain”: equipment installation finished, the military on behalf of Zhang Wei does not agree and acceptance. Things, “zombies” in a plug. Zhang Wei found that, because when the cable laying into poor effort in order to insert the jack plug. He said: “so easy to break, you must re-install!”
We must find the reasons for quality problems. Army on behalf of Xu Jin-liang Regulator Fastener Torque is not found in compliance, so that equipment factory three times rework. After compliance, Xu Jin-liang not give up, persist to find out the reasons. He and plant technology, together with the nut on the bolt thread size of each measurement, one by one to do chemical composition analysis, mechanical properties of each doing testing, and finally the identification of “super bad” reasons, so that follow-up to the quality of products is guaranteed.
New submarine massive and the country’s 22 provinces, seven major industry groups, 20 design units, more than 500 factories involved in the construction. The face of enterprise restructuring, the market economy, the new environment, the military on behalf of room for adherence to “national security paramount, equipment, construction quality first”, to play a leading role in the military, brave improve coordination, promote the military, factory, the largest cooperative to ensure the construction quality.
Power plant control equipment and more interfaces there are thousands of participating in a number of design units, each interface is given not uniform, do not match. Zushi, director of the trial served as the military representatives Liu Zhizhong, repeated communication with the design department, adhere to standards, unified voltage, current interface; his trial diagram also found that some units in order to easily design and production, have larger equipment size, so that the submarine control rooms are crowded. He also and design, together with the right control system for each device one by one study, provides a unified size, and control room layout optimization. Control system for the FBI ahead of a months to complete.
Loyalty: Youth bearing glory and dreams of blood cast submarine “keel”
All tests of the submarine, we should limit the number of the most dangerous and unpredictable diving.
Chief representative of the CHAI Xiao-wen, deputy chief representative of the Fan-Ming Meng, Chen Ai-Zhi, 14 were duty-bound to participate in a new type of submarine boat limit of two types of the first deep dive test.
Army on behalf of Wang Sheng 1 week before the dive medical examination and found that the Minister of the liver the size of a 5 cm mass, initially diagnosed as hemangioma. His hesitation to make a choice: “first dive, after surgery!”
Submarine dive review, every cabin, every piece of equipment, every cable, every weld, their inspection, testing is more than six times!
Compressive deformation in the boat dive experience. The main circulating sea water system pipe, “bellows” As soon as the bursting of the influx of sea water per second would have a large number of tanks, causing an instant crash boat tragedy. The potential pre-test and calculation, found that “bellows” linear deformation changes in depth when the dive to the limit, it may even break approaching the limit of its tolerance. “Must ensure that everything goes!” Chief representative of the Cai Xiao-Wen Ma Jun, who led the repeated calculation, verification, to take the weight of “transfer” measures, successfully resolved the security problems.
China’s new submarine deep dive test a complete success!
Slipway and sweat, blood and cast the “blue whale.”
Fan-Ming Meng, deputy chief representative at the test site is to stay for 13 months; the military on behalf of Wang Sheng continuous 22-month experiment in the field to participate in sailing, sea more than 130 days out of full-qin, a voyage does not fall … …
“Saturday undertake not to rest on Sundays does not guarantee that” This is a portrayal of the military on behalf of overtime over many years.
From the start of the day the new submarine, the military representatives of the average overtime hours is equivalent to three years of the normal workload.
Before the Spring Festival in 2004, the first boat main pump motor failure. Military Representative Office bulletin board that appears in five Chinese characters “that it had no New Year”! Lunar New Year’s Eve afternoon and started this morning, TANG Yao-Yang, Xiao-Ming Xu boarded the train rushed to the manufacturer, on-site dismantling the main pump motor, analyze the causes, from the first form stem to the sixth days, until the troubleshooting.
Every 10 years, the Spring Festival, the military on behalf of a holiday is only 2 days.
Hai-wide 6-month pregnant wife, check out the suffering from pregnancy-induced hypertension syndrome. Mission at sea Zhang W, until the day before his wife give birth come back. Newborns only 1800 grams, the doctor told: the child has severe dangerous period of 7 days. But the first 5 days, Zhang W had any connection with the boat to sea. Today, the brain child came to a disability, 3 year old and you still can not speak.
Even so, the military representatives are still no regrets in love with their cause. Military Representative Lu Hai Jin gave up on his choice of hiring a company-paid feel pride: “The new submarines worldwide attention, but personally involved in the construction of submarines, few can?”
New submarine traveling in the ocean, laden with military representatives of the glory and the dream: The blood of the Republic of youth and build strong underwater Great Wall!
