Rebirth of Military Workers

There are three places where the domestic heavy industry is most concentrated, the old industrial base in the Northeast, the surrounding area of ​​Qinling Mountains, and the strategic rear area in the hinterland of the southwest.

The large aircraft in the Shanghai stock market is not because the heavy industry base there is good, but the Shanghai stock market conditions were relatively good that year. Compared with the heavy industry supporting facilities in other places, this side does not actually meet the production of large aircraft.

Many spare parts are transported from around the Qinling Mountains and the Northeast.

If you can't cooperate with Qin Fei, Xie Kai can only choose Rongcheng in the southwestern hinterland.

The northeast is too far away, and the supporting units for various large aircraft are not as perfect as the southwest.

For the purpose of national defense strategy and security, many important core units were arranged in the hinterland of the southwest in the country's third-line construction, making it safer here.

"I think we first ask them how much they produce each year, whether it will affect our production and improvement. Once missed, such cooperation opportunities will be difficult to meet again." Ouyang Shaoxiu does not want to lose such opportunities.

Su Xingguo also nodded, "Yes, even if they produce one each year, on our side, we can do a lot of supporting equipment, and there are tens of millions of funds a year."

"If they produce too much, they will severely squeeze Yunba's production and improvement work." Sun Daogan worried about affecting their projects, "Yunba transformation work must continue, they lack scientific research personnel, insufficient assembly technicians... …"

"We mainly focus on Yunba, they remodel Yunshi, and when they are able, they will undertake some of their technical projects, or merge with projects with little difference in technology from ours." Regarding the concerns of Sun Daogan and others, Ouyang Shaoxiu did the same before. There are too.

That's why they hope that the Yunshi team will participate in their project.

Funding can be strongly supplemented, and technical strength can also be enhanced.

"Talk to them again, as long as it doesn't affect our project, we can cooperate. What do you think?" Sun Daogan asked everyone.

Others agree with this statement.

They can't lose their current main business in order to cooperate with the Yunshi project team.

There are many technical flaws in the Yun-10. By then, the large aircraft will not have the technology, and the small aircraft will not be able to make breakthroughs, and they will not be able to communicate with the military.

"How many planes can you produce each year?" Xie Kai asked them after Su Xingguo asked them.

The output of Yunba is unlikely to be large. From its finalization in 1980 to the present, only 25 have been produced in five years.

The Air Force does not have much equipment for such aircraft.

Until the real Yun-9 came out, the number of Yun-8 equipment was only about 100, including more than 20 aircraft for civil aviation and export.

Almost the annual output is about five.

For such a large aircraft production plant, this number is really embarrassingly small.

"With the maximum production capacity, it can produce about 8 aircraft per year." Su Xingguo is not lying about this matter.

Production is now almost at a rate of five aircraft per year.

Modifications are being made while producing, and other types of aircraft are also being produced at the same time.

"In other words, your idle capacity can't provide us with the production of one YX-10 each year?" Zheng Yucheng asked.

With the current situation of Yunshi, it is impossible to produce one aircraft a year.

However, the modification work requires a lot of experiments, and the prototype is indispensable.

Therefore, at least one spare capacity per year must be reserved.

"This is almost the situation." Su Xingguo nodded and said.

Qin Fei is huge, even larger than the 404 base.(Read more @ hotmtlnovel.xyz)

This little production capacity every year is shocking.

Perhaps the scale used to produce old-fashioned aircraft is not small, but the most important thing is that this factory has complete supporting facilities. Qin Fei's own factory can manufacture all parts of the aircraft, from material production to processing.

This is true of many domestic enterprises.

Even the 404 base is the same.

Although the sparrow is small and has all five internal organs, each unit pursues comprehensiveness when constructing, nothing else, because all parts and accessories can be produced in their own factories when the war breaks out, and the production will not be affected by the logistics and transportation problems.

"You guys, what has become an obstacle to our cooperation is your production capacity, can you understand it this way?" Xie Kai asked.

Sun Daogan looked at him, "Didn't you all make it clear?"

"We don't need to produce one each year. In the initial stage, it was only once every two years." Zheng Yucheng said.

"You also said it, it's just the beginning." Su Xingguo reminded Zheng Yucheng.

The production process of Yun-10 is more complicated.

"I don't know if you have heard of a pulsating production line?" Xie Kai asked.

Low production capacity will naturally increase production capacity.

When visiting the Yunba production workshop in the morning, Xie Kai discovered that each aircraft was densely covered with tooling and equipment, instead of the pulsating production line commonly used in aircraft production later.

"Pulsating production line? Have heard of it, but don't know the specific situation. Do you know?" Su Xingguo's eyes lit up.

Zheng Yucheng does not know what a pulsating production line is, even Ma Fengshan and others do not know.

How did Xie Kai know that no one pays attention at the moment, they pay attention to what a pulsating production line is.

"Actually, I don’t know very well. I used to hear about assembly line production. Last time I saw assembly line production at Xiangjiang. The entire assembly line, each job position, is only responsible for a small process..." In order not to be asked, Xie Kai can only talk about the assembly line first.

The aircraft pulsating assembly line is actually an optimized assembly line.

“When I heard about the pulsating production line, I didn’t even know what was going on. When we took over the Yunshi project and learned about the production process of Yunshi, I was thinking, if Yunshi needs mass production, we would like to The production capacity of the factory can produce several aircraft a year..." Xie Kai said slowly.

He has said so much, he has not yet started to say what a pulsating production line is.

Qin Fei's people were anxious and couldn't urge them.

Zheng Yu's achievements are different. He was extremely upset by Xie Kai's speech-hungry behavior, and immediately interrupted Xie Kai's words angrily, "You just say, don't sell your appetites."

"What are you worried about? I have to say no from the beginning?" Xie Kai glared at Zheng Yucheng.

Everyone is helpless.

"All domestic aircraft production uses traditional methods. The aircraft is the center. The tooling equipment is arranged around the aircraft. Assemblers then take fixed positions to work according to the final assembly tasks... The entire production process mostly relies on manpower. Workers. The work intensity is high, and a slight negligence may cause missed installation or missed inspection. During the prototype production process of Yunshi, seven large-scale quality troubleshooting work has been carried out, and thousands of problems have been found..." Xie Kai said This is not a blow to the Yun-10 team.

Ma Fengshan and Cheng from time to time both looked embarrassed.

What Xie Kai said is the truth, and this is what they told Xie Kai.

Seven large-scale quality inspections have allowed them to gradually form a quality inspection system. Even so, it is still difficult to ensure stable quality.

"If we divide the aircraft production process into several important stages, the first stage is the assembly of small parts into large parts, such as the installation and testing of the flaps and ailerons of the wing parts, and there is no problem before proceeding to the second stage. ."

As soon as Xie Kai said these words, the entire conference room was silent. Ouyang Shaoxiu, Ma Fengshan and others quickly recorded these words.

As long as you know the industry, you know that, after the job is subdivided, not only can the proficiency of the workers be quickly improved, but also the quality can be ensured from all aspects.

"The second phase of the work involves the installation of the six major components of the aircraft's front fuselage, middle fuselage, rear fuselage, left and right wings and tail section, as well as pipelines, cables and various functional systems. These large components are also in the first At this stage, the general installation and preliminary inspection have been completed..."

The various parts of the aircraft are installed separately, and they are inspected before the overall installation to reduce the missing parts and failure rate to a minimum.

In this way, the quality of the entire production process becomes controllable.

"The third stage is to install the main landing gear and floor, insulation blankets, and secondary structural parts."

"The fourth stage is to decorate the interior of the aircraft, install auxiliary power units and conduct preliminary tests on them."

"The work of the fifth stage is to carry out hydraulic system, landing gear retractable test, avionics test, flight control test, etc."

Xie Kai briefly introduced the work area division of the pulsating production line from Boeing that he remembered in his mind.

"This method is very good. In this way, not only will the production efficiency be greatly improved, but the quality problem will also be effectively solved." Ouyang Shaoxiu took the lead in slapped after Xie Kai finished speaking.

The benefits of the method proposed by Xie Kai are obvious to anyone who understands management.

The biggest problem with domestic production is low efficiency and difficult quality control.

"Not only is the efficiency improvement and quality controllable, in the production process, every stage of the work is completed, the aircraft as a whole moves forward, each work area is directly responsible for the work they undertake, and there are fewer inspections... At the same time, we can increase the utilization rate of tooling and develop some auxiliary equipment to make production more efficient..." Xie Kai said.

"For example?" Su Xingguo was also interested in this mode of production.

"The installation of the six major components of the aircraft. Modular design and manufacturing are used. The pipeline and cable installation of each component is completed before the final assembly to form a large-component modular structure. During the final assembly, the tooling is designed according to the location, and only a few components need to be brought together , And then install it. In this way, the work becomes easier..." Xie Kai said.

The emergence of the pulsating production line will greatly reduce the time and tooling required for the final assembly of the aircraft, while also making the quality more controllable.

"This is a pulsating production line that I understand. I don't know if it's the case." Xie Kai said with a smile on the faces of many people.

Qin Fei once completed the first domestic pulsating production line. In this era, as long as they really pay attention to it, they will also complete the first domestic line. In terms of assembly methods, they will be the first to be in line with international standards.
