Chapter 305 Y-30 Final Assembly Offline
Chapter 3 and 30 Y-[-] final assembly off the assembly line
On October 10th, XAC, in the newly built huge assembly workshop, two huge four-engine aircrafts have completed the final assembly at this time, and the four 'Qinling engines' hanging under their wings are equally huge!
Qin Yuanqing and others came to the final assembly workshop and saw the two completed Y-30 transport aircraft. They were very happy and satisfied with XAC's efficiency. They completed the final assembly of two Y-30 strategic transport aircraft in such a short period of time. .

"Leaders, once the test flight is completed and the Y-30 enters the mass production stage, our group plans to adopt pulsating production, and the production speed can be increased several times by then!" XAC's Mr. He said proudly.

"You XAC have done a good job, and you have not disappointed your superiors. It seems that it is right to specialize in the technology industry. You XAC will focus on producing transport aircraft in the future. If you stick to this, you will be able to make some achievements!" AVIC's The leader nodded and said.

秦元清也觉得这说法是对的，一个集团负责一个领域。在中航的规划下，成飞生产三代机、四代机，比如现在就在生产J10及改进型、J20A、J20B系列战机。而西飞公司主要生产运输机，包括Y-20、Y-30系列运输机以及战略轰炸机、空中加油机、预警机。陕飞则是生产Y-8、Y-9以及改进的巡逻机、航测机、邮政机、无人机母机系列。沈飞则是生产国产S-27、教练机之类。

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

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 in the factory building, it looks even more shocking.

当然这个总装厂房也是无比的巨大，毕竟Y-30的长度超过了50米、高度将近17米、翼展50多米，而这个总装厂房可以一次性生产2架Y-30还有剩余，估计总装厂房的长度应该有500米、宽度差不多250米，日后估计可以进行多架次的同时总装。

Overlooking the Y-30 assembly line from the sky, it looks like a huge shipyard.

As for the aircraft pulsating production line technology mentioned by Mr. He of XAC just now, it is a manufacturing technology invented by Boeing Company of America. 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 Ford Motor Company's automobile production line.This kind of pulsating production line can set the buffer time, and it does not have high requirements for the production cycle. When there is a problem in a certain part of the production, the entire production line can be stopped or left to the next station to solve it. When the aircraft assembly work is completed After that, the production line pulses once.

Before Yang Wei came to him, Qin Yuanqing was so entangled that he went to the FAW Group to see the automobile production line, and then based on the existing information, he conquered the aircraft pulsating production line technology, and Chengfei immediately invested in it, making the J20B The production capacity of the company has been greatly improved, and 50 J20Bs can be produced a year, thereby reducing the cost and reducing the cost of the J20B to 1.2 million yuan.

It is precisely because of the power of the pulsating production line that other domestic aircraft manufacturing groups have also started to launch pulsating production lines to speed up the manufacture of aircraft.

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

After all, this Y-30 was born in his hands. He spent a lot of learning coins and hard work on this strategic transport aircraft. Now that the prototype is ready to be rolled off the assembly line, Qin Yuanqing is naturally happy and excited.

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

"Academician Qin, this is the first time that Xifei has manufactured 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 complete the manufacture of Y-30 smoothly and on time, he has been living in the group and never even returned home. The entire leadership put the manufacture of Y-30 on the top priority of XAC, and concentrated the best engineers of XAC, and finally Basically completed the task on time.

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

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

Then XAC lost face and tried to win over this group of R&D personnel. As a result, 10 of the most difficult aero-engine researchers were poached.

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

The Y-30 is definitely the first time that 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 Y Next to the -30 strategic transport plane, it looks like a little one.Even the Y-20 transport aircraft is a circle smaller than the Y-30 strategic transport aircraft.

Even the domestically produced large aircraft C919, which has just rolled off the assembly line at the Pudong base, is much smaller than the Y-30. After all, the domestically produced large aircraft C919 actually has a total length of 38 meters, a wingspan of 35.8 meters, and a height of 12 meters. The one in front of him also belongs to the younger brother level.

“11月10日将进行全机静力实验，12月30日交付试飞中心，2016年1月30日完成高速滑行抬前轮试验，2016年2月29日进行首飞。完成首飞后，另一架进行地面强度试验和疲劳试验，争取2017年~2018年进行批量生产交付部队使用！”中航工业的领导说着Y-30的时间表。

A very important reason why J20B can complete its first flight and enter mass production so quickly is because many of its technologies have been verified on J20A, and the engine has also undergone thousands of hours of ground operation tests with aeroengine 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 the Y-20, which took more than 20 years and nearly 5 years from the first prototype to service.

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

"Mr. He, in order to speed up the experimental test of the aircraft, our institute will allocate another 10 billion to produce two more planes for testing together, and strive to complete all the flight tests in 2. We hope that after completing all the tests, AVIC will quickly pay us one. A technical buyout fee, otherwise, if it is extended for a few more years, the people under me will be poached by you, and I will become a poor commander myself!" Qin Yuanqing said with a smile.

"Haha~~"

Hearing what Qin Yuanqing said, the other leaders burst out laughing.

In fact, Qin Yuanqing has no opinion on Xifei's poaching. After all, the people below are interested in manufacturing aircraft and want to work in the front line. This is their own choice. Qin Yuanqing can't stop their aspirations. On the contrary, Qin Yuanqing is very happy .

This is conducive to the development of the industry and is a great thing!
As the saying goes, a single flower is not spring, and a garden is full of spring when a hundred flowers bloom together.

The Aero-Engine Research Institute not only has R&D tasks, but also a place for cultivating talents. We should not keep all talents in our own hands, but let them come out and fly high.

So far this year, more than 60 members of the Aero-Engine Research Institute have submitted resignation applications, and these people will go to XAC, Chengfei, Shenfei, Shangfei, Hangfa Power and other aircraft manufacturing units. Approved, but also personally encouraged them to work hard in the new unit.

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

Compared with the Everest engine and the Gefeng engine, the Y-30 is actually more meaningful to Huaxia, because it not only means that Huaxia 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, refueling aircraft, strategic bombers, electronic reconnaissance aircraft, etc.Similarly, in the civilian field, no matter it is manufacturing technology, materials, engines and other technologies, it can be used on large aircraft, not only short-to-medium-range and medium-sized aircraft, but also long-range large aircraft. In addition to passenger aircraft, commercial aircraft It will also develop accordingly.

It can be said that the technology included in Y-30 is immeasurable. If Huaxia explores it step by step, it will at least spend hundreds of billions of research and development costs and invest a lot of manpower and material resources, and it will be possible to develop it for more than ten years.

But now Qin Yuanqing brought his own group of people without the country paying a penny for research and development. Relying on his outstanding ability, he abruptly produced the Y-30 transport aircraft in a short period of time.

It can only be said that this has already reached a consensus in China, and the role of one top scientist exceeds the role of hundreds of top scientists.

Otherwise, you can't explain how Qin Yuanqing overcame technical difficulties one by one, and forcibly brought Huaxia 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 treatment level of top talents, but also increases the number of top talents who are abroad to return to work.In meetings, on TV, in newspapers, and at international conferences, relevant leaders will repeatedly emphasize that the 21st century is the century of talents, and talent strategy is a grand strategy that needs to be given great attention and cannot be ignored for a moment.

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