Rebirth of science and technology academic master

Chapter 306 Y-30 final assembly rolls off the assembly line

On October 30, in the newly built huge assembly workshop of XAC, two huge four-engine aircraft had completed their final assembly. Equally huge were the four ‘Qinling engines’ hanging under their wings!

Qin Yuanqing and others came to the final assembly workshop and saw the two Y-30 transport aircraft that had been completed. They were very happy and satisfied with XAC's efficiency in completing the final assembly of two Y-30 strategic transport aircraft in such a short period of time. .

"Dear leaders, once the test flight is completed and the Y-30 enters the mass production stage, our group plans to adopt pulse production, and the production speed will be increased several times by then!" Mr. He from XAC said with pride.

"You XAC did a good job and did not disappoint your superiors. It seems that it is right to specialize in the industry. From now on, you XAC will make good efforts to produce transport aircraft. If you stick to this, you will definitely be able to make some achievements!" AVIC's The leader nodded and said.

Qin Yuanqing also felt that this statement was correct. One group was responsible for one area. Under AVIC's planning, Chengdu Aircraft Corporation of China produces third-generation and fourth-generation aircraft. For example, it is currently producing J10 and improved, J20A, and J20B series fighters. XAC mainly produces transport aircraft, including Y-20 and Y-30 series transport aircraft, strategic bombers, aerial tankers, and early warning aircraft. Shaanxi Aircraft Co., Ltd. produces Y-8, Y-9 and improved patrol aircraft, aerial survey aircraft, postal aircraft, and drone aircraft series. Shenfei produces domestic S-27, training aircraft and the like.

They came to the final assembly plant of the Y-30 strategic transport aircraft this time because tomorrow the Y-30 strategic transport aircraft will hold a grand prototype off-line ceremony.

I have to say that standing next to the Y-30 strategic transport aircraft, everyone looks so small. The Y-30 strategic transport aircraft is too big, especially inside the factory, it looks even more shocking.

Of course, this assembly plant is also extremely huge. After all, the length of the Y-30 is more than 50 meters, the height is nearly 17 meters, and the wingspan is more than 50 meters. And this assembly plant can produce 2 Y-30s at one time and there is still some leftover. The length of the final assembly plant should be 500 meters and the width almost 250 meters. It is estimated that multiple sorties can be assembled simultaneously in the future.

Looking down from the sky, the Y-30 assembly line looks like a huge shipyard.

As for the aircraft pulsating production line technology just mentioned by Mr. He of XAC Group, it is a manufacturing technology invented by Boeing Company in the United States. This advanced aircraft assembly production line technology is somewhat similar to the mobile automobile production line, but it is different. . Boeing's technology was developed from the Ford Motor Company's automobile production line. This pulsating production line can set the buffer time and does not require high production rhythm. When a problem occurs in a certain link of production, the entire production line can be stopped or left to the next station to solve. When the aircraft assembly work is completed, Afterwards, the production line pulses once.

Before Yang Wei came to find him, Qin Yuanqing was so entangled that he went to the FAW Group to see the automobile production line. Then based on the existing data, he conquered the aircraft pulsating production line technology. Chengdu Aircraft invested in it immediately, making the J20B The production capacity has been greatly improved and can produce 50 J20Bs a year, thereby reducing costs and reducing the cost of J20B to 120 million yuan.

It has demonstrated the power of the pulsating production line, so other domestic aircraft manufacturing groups have also begun to launch pulsating production lines to speed up the manufacturing of aircraft.

"Our Y-30 strategic transport aircraft is really bigger and more majestic than imagined! Now let's see how it performs on its first flight. I hope everything goes smoothly!" Qin Yuanqing looked very happy.

After all, this Y-30 was born in his hands. He spent a lot of learning coins and efforts on this strategic transport aircraft. Now that the prototype has completed its final assembly and is about to roll off the production line, Qin Yuanqing is naturally happy and excited.

After the transport aircraft completes the final assembly and rolls off the production line, the next step is the first flight, and then various test flights. Only after completing a series of tests and solving a series of problems can it enter the mass production stage.

"Academician Qin, this is also the first time that XAC has built such a large aircraft. The Y-20 is much smaller than it. It is really not easy to say!" Mr. He said with emotion.

In order to successfully complete the manufacturing of the Y-30 on time, he has been living in the group and has not even returned home. The entire leadership has listed the manufacturing of the Y-30 as a top priority for XAC and gathered the best engineers from XAC. Finally, The task was basically completed on time.

During this process, many manufacturing problems were encountered, which were solved by a group of outstanding engineers from XAC and R\u0026D personnel from the Aero Engine Research Institute, Harbin Institute of Technology, and Beihang University. This greatly improved XAC's technical strength.

Within half a year, XAC made breakthroughs in more than 300 manufacturing technologies and even revised its quality management system.

Then XAC Group lost its face and recruited these R\u0026D personnel. As a result, 10 of the most difficult aero-engine researchers were poached.

"When I came to XAC this time and saw these two Y-30 strategic transport aircraft prototypes, I saw that XAC's aircraft manufacturing technology and capabilities are indeed second to none in domestic large aircraft manufacturing!" Qin Yuanqing said to XAC The leader of Fei Group gave a thumbs up.

The Y-30 is definitely the first time China has produced such a large aircraft. Compared with medium-sized tactical transport aircraft such as the Y-8 and Y-9, the Y-30 strategic transport aircraft is much larger. If a Y-9 is placed in the Y Next to the -30 strategic transport aircraft, it looks like a little dot. Even the Y-20 transport aircraft is smaller than the Y-30 strategic transport aircraft.

Even the domestic large aircraft C919, which has just been officially assembled at the Pudong base, is still a lot smaller than the Y-30. After all, the domestic large aircraft C919 has an actual total length of 38 meters, a wingspan of 35.8 meters, and a height of 12 meters. Compared with the Y-30 The person in front of me is also at the younger brother level.

"The static test of the whole aircraft will be carried out on November 10, and it will be delivered to the flight test center on December 30. The high-speed taxiing nose wheel lifting test will be completed on January 30, 2016, and the first flight will be carried out on February 29, 2016. After completing the first flight, The other one will undergo ground strength tests and fatigue tests, and we will strive to mass-produce it and deliver it to the troops in 2017 to 2018!" The leader of AVIC said about the Y-30 timetable.

A very important reason why the J20B was able to complete its first flight, test flight testing and enter mass production so quickly is because many of its technologies have been verified on the J20A, and the engine has also undergone thousands of hours of ground operation testing under aircraft engine power.

The Y-30 can be said to be a brand new model, and it will take a lot of time to complete the entire test.

But this progress is much faster than that of the Y-20. It took more than five years and nearly six years for the Y-20 to go from the first prototype to service.

Even so far, the Y-20 transport aircraft has not yet been mass-produced and put into service. Instead, it is still in the test flight stage and undergoing a series of tests.

"Mr. He, in order to speed up the experimental testing of the aircraft, our institute has allocated another 1 billion to produce two more aircraft and conduct testing together, and strive to complete all flight tests in 2018. We are counting on AVIC to pay us a fee after completing all the tests. A technical buyout fee, otherwise if it is extended for a few more years, all the people under me will be poached by you, and I will become a polished commander!" Qin Yuanqing said with a smile.

"Haha~~"

The other leaders burst out laughing when they heard what Qin Yuanqing said.

In fact, Qin Yuanqing didn't have any opinion on XAC recruiting people. After all, the people below were interested in manufacturing aircraft and wanted to work on the front line. This was their own choice, and Qin Yuanqing could not stop their ambition. On the contrary, Qin Yuanqing was very happy. .

This is conducive to the development of the industry and is a great thing!

As the saying goes, it is not spring when a single flower blooms, but when a hundred flowers bloom, the garden is full of spring.

The Aero Engine Research Institute not only has research and development tasks, it is also a place to cultivate talents. We cannot keep talents in our own hands, but let them come out and fly high.

So far this year, more than 60 people at the Aero Engine Research Institute have submitted resignation applications, and these people will go to aircraft manufacturing units such as XAC, Chengdu Aircraft, Shenyang Aircraft, Shanghai Aircraft, and Aviation Engine Power. Qin Yuanqing did not set any obstacles. He approved it and personally encouraged them to work hard in their new unit.

"Academician Qin, we have to thank you. Once the Y-30 enters service in batches, China will take a big step towards becoming a large air force. When the time comes, the technology buyout fee will definitely not be unfair to your research institute!" Director of AVIC Said with a long smile.

Compared with the Everest engine and the Gefeng engine, the Y-30 is actually of greater significance to China, because it not only means that China will have an advanced strategic transport aircraft, but also means that it will be born on this platform in the near future. Early warning aircraft, tanker aircraft, strategic bombers, electronic reconnaissance aircraft, etc. Similarly, in the civilian field, manufacturing processes, materials, engines and other technologies can all be used on large aircraft, which are not just short- and medium-range medium-sized aircraft, but also long-range large aircraft. In addition to passenger aircraft, business aircraft will also develop accordingly.

It can be said that the technology included in the Y-30 is immeasurable. If China were to explore step by step, it would have to spend at least hundreds of billions in research and development costs, invest a lot of manpower and material resources, and it would take more than ten years to develop it.

But now Qin Yuanqing, with his own group of people, did not need the country to pay any R\u0026D expenses first, and relied on his outstanding ability to produce the Y-30 transport aircraft in a short period of time.

It can only be said that this has formed a consensus in the country. One top scientist is more important than hundreds of top scientists.

Otherwise, you can't explain how Qin Yuanqing overcame technical difficulties one by one and brought China to the world level in the field of research.

It is also for this reason that the country pays more and more attention to top talents. It not only improves the salary level of top talents, but also increases the number of top talents abroad to return to work in China. Relevant leaders will repeatedly emphasize at conferences, on television, in newspapers, and at international conferences that the 21st century is the century of talents, and talent strategy is a major strategy that requires great attention and cannot be ignored for a moment.

The foreign affairs department is also increasing its work to strengthen communication with top talents, hoping that these talents who have settled overseas can return to China to use their talents.

Today there will still be ten updates
