A big country of aerospace with black technology

"The problem of aircraft production can actually be solved by improving the production line."

Now the production of fighter jets, including the latest J-10, all use fixed-station production lines.

Fixed station production line, as the name suggests, the aircraft is in the same position throughout the production process.

Assuming that there are a thousand processes in aircraft production, then a thousand groups of workers are required to go to the same fixed station to assemble the aircraft according to the assembly sequence.

In this way, the assembly speed is very slow, and it may take half a month to assemble an aircraft.

A whole production line only assembles dozens of aircraft a year.

This is also the current status of domestic aircraft production. Of course, most aircraft in the world are produced in this way.

After Zhang Xingyang chatted with Song Tianxing about the use of composite materials on aircraft, he talked about the mass production of aircraft.

Due to various reasons, the mass production of the J-10 will not go smoothly, the most important of which is the issue of aircraft assembly.

In the absence of a substantial increase in the number of workers, the efficiency of a fixed-site production line is very low.

"In fact, we can learn from the automobile production industry. The continuous flow production line they use is much higher in manufacturing efficiency!"

Of course, Song Tianxing could understand Zhang Xingyang's suggestion, but the difficulty of final assembly of an airplane was much higher than that of a car.

Not so easy to solve.

"Automobile assembly can be assembled continuously during continuous movement because the scale of their equipment is not complicated, and the difficulty of final assembly is not great."

"The various parts of the aircraft assembly are too complicated, and it is impossible to assemble them in non-stop movement like the automobile production process."

Song Tianxing only thought of Zhang Xingyang, and didn't particularly understand the difficulty of aircraft manufacturing.

Give him a little explanation of the difficulty here.

Although the continuous flow production line can indeed greatly improve the efficiency of final assembly, this production method is not particularly used in aircraft final assembly.

Because the parts of the aircraft are far more than the parts of the car in terms of size and complexity.

"It's really unrealistic to completely use a continuous flow production line, but using a continuous flow production line in part of the aircraft final assembly process can also greatly improve the efficiency of aircraft final assembly!"

Zhang Xingyang naturally knew what Song Tianxing was thinking.

But Zhang Xingyang really wanted to know more about flow production.

When Song Tianxing heard that some of them adopted continuous flow production lines, he seemed to have a vague sense of what Zhang Xingyang wanted to express, so he said quickly:

"How the hell is partial adoption?"

"Speak carefully!"

"For example, we can divide the final assembly production of fighter jets into five parts, and carry out assembly operations on five parts of the aircraft at five relatively fixed stations at the same time."

"After the assembly of each part is completed, each part is moved by various means."

"This is equivalent to assembling different processes of multiple aircraft at the same time, which can greatly improve the efficiency of the final assembly of the aircraft."

"And because the assembly isn't done while the plane is moving, it's just done when the plane is stationary."

"So the construction difficulty of the production line is much smaller than that of the continuous flow production line."

Song Tianxing's eyes lit up little by little when he heard Zhang Xingyang's explanation of future generations' understanding of the pulsating production line of aircraft.

It's like a hungry wolf seeing a fat prey.

"Xing Yang, I didn't expect you to have such a novel and profound insight into the industrial production of aircraft, you are indeed a genius!"

In fact, this kind of knowledge will already belong to the bad street stuff after decades, and anyone who pays a little attention to this aspect can know it.

Not to mention that after hundreds of years, the production of aircraft in the atmosphere has already achieved the era of fully automated production.

But at the time point of the 1990s, the pulsating production line was still a very fresh and advanced concept.

We must know that the first pulsating production line in the aviation manufacturing field has not yet appeared at this time. At least three years later, Boeing will launch the first aircraft pulsating production line, which will be regarded as the first pulsating production line in the world's aviation manufacturing field.

"Actually, this is not a new concept."

Zhang Xingyang is not particularly excited. After all, if we really want to talk about the pulsating production line, there are some precedents in other fields.

It's just that in the field of aviation manufacturing, no one has formally proposed it.

"We did the same for automobile production when heavy industry was underdeveloped."

"Unable to establish a continuous flow production line, then reduce the manufacturing requirements and partially adopt flow assembly."

Song Tianxing is not a young man anymore, he has naturally experienced all kinds of manufacturing industry in the past years, and has understood this period of history.

"Moreover, we can iteratively upgrade the production line in the future, and adopt modular transfer for most of the components to improve the efficiency of the production line."

Modular production is still a new concept at this time, but everyone is doing research, so Song Tianxing also has some understanding.

"Modular production efficiency can indeed be improved, but this requires adjustments to the entire assembly line, and the time, manpower and material resources required are not a small number."

"Chengfei currently does not have so much transformation funds to transform the production line."

Although the idea is very good, it takes a lot of money to turn it into reality.

"The export of Chengfei's aircraft is not very smooth now, and everyone in the world is seeking to replace it with a third-generation aircraft."

"Like the J-7, which kept exporting and earning foreign exchange in those years, it can't be sold internationally these years."

Song Tianxing kept talking about Chengfei's current difficulties, and he was a little worried about funds.

"Funding is indeed a big problem, but if Chengfei really wants to build a pulsating production line, the country and the Air Force probably won't be stingy with funding."

"After all, if the pulsating production line is completed, the production efficiency can be increased by four or five times, at least."

"A production line can at least produce nearly a hundred J-10s every year. I don't believe those bosses in the Air Force are not tempted!"

"As long as you disclose this news to them, I don't think you need to find money. The bosses will take the initiative to ask the country for money for you!"

Zhang Xingyang has a different opinion. These days, the air force's desire for advanced fighter jets has reached a level of almost hunger.

As long as there are a large number of J-10 fighter jets for them, Zhang Xingyang has no doubt that they can even make it to the top.

At this time, Song Tianxing also understood what Zhang Xingyang meant, and said:

"That's right. After knowing that our first flight of the J-10 was successful, several Air Force chiefs asked when they would be able to mass-produce and equip troops."

"If they know that they can produce hundreds of planes a year, they will probably advance this matter no matter what!"
