Chapter Seventy-Three: Pulsating Production Line (First Order!) )
"The problem of aircraft production, we can actually solve it by improving the production line."
Now the production of fighter jets, including the latest J-10, is a fixed station production line.
As the name suggests, the aircraft is in the same location throughout the production process.
Assuming that there are 1,000 processes in aircraft production, then there will be 1,000 groups of workers to assemble the aircraft at the same fixed station according to the assembly sequence.
This 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 situation of aircraft production in China, of course, in fact, most of the world's aircraft are produced in this way.
After Zhang Xingyang and Song Tianxing finished chatting about the use of composite materials on aircraft, they talked about the mass production of aircraft.
For various reasons, the mass production of the J-10 will not go very smoothly, the most important of which is the aircraft assembly problem.
In the absence of a significant increase in the number of workers, the efficiency of the fixed-station production line is very low.
"In fact, we can learn from the automobile production industry, and the continuous flow production line they use is much higher in terms of manufacturing efficiency!"
Zhang Xingyang's suggestion, of course, Song Tianxing can understand, but the difficulty of aircraft assembly is much higher than that of cars.
Not so easy to solve.
"The reason why the final assembly of the car can be assembled continuously in continuous motion is that the scale of their equipment is not complex and the final assembly is not very difficult."
"The various parts of the aircraft assembly are too complex to be assembled in a constant movement like the automobile production process."
Song Tianxing only acted as Zhang Xingyang, and he didn't particularly understand the difficulty of aircraft manufacturing.
Explain to him a little bit about the difficulty of the problem.
Although the continuous flow production line can indeed greatly improve the efficiency of the final assembly, the aircraft final assembly does not particularly use this production method.
Because the parts of an airplane far exceed the parts of a car in terms of size and complexity.
"It is indeed unrealistic to completely adopt a continuous flow production line, but the use of continuous flow production line in part of the process of aircraft assembly can also greatly improve the efficiency of aircraft assembly!"
What Song Tianxing thought, Zhang Xingyang naturally knew.
However, Zhang Xingyang really wants to do more about mobile production.
When Song Tianxing heard that some of the continuous flow production lines were used, he seemed to vaguely feel some of the meanings that Zhang Xingyang wanted to express, so he hurriedly said:
"How exactly is it partially adopted?"
"Tell me about it!"
"For example, we can divide the final assembly production of fighter jets into five parts, and at the same time assemble five parts of the aircraft at five relatively fixed stations."
"After the parts are assembled, the parts are moved again by various means."
"This is equivalent to assembling different processes of multiple aircraft at the same time, which can greatly improve the overall assembly efficiency of aircraft."
"And because we don't do assembly work when the plane is moving, we only do assembly work when the plane is stationary."
"Therefore, the construction of the production line is much less difficult than that of the continuous flow production line."
Song Tianxing listened to Zhang Xingyang's explanation of the later generations' understanding of the aircraft pulsation production line, and his eyes lit up little by little.
It's like a hungry wolf that has seen a fat prey.
"Xingyang, I didn't expect you to have such a novel and profound insight into the industrial production of aircraft, you are worthy of being a genius!"
In fact, this knowledge is already a rotten thing after a few decades, and anyone who pays a little attention to this aspect can know it.
Not to mention the fact that hundreds of years later, the production of aircraft in the atmosphere has long been fully automated.
But at this point in time in the 90s, the pulsating production line was still a very new and advanced concept.
You must know that at this time, the first pulsating production line in the field of aviation manufacturing has not yet appeared, and it will not be until Boeing launches the first aircraft pulsation production line at least three years later, which can be regarded as the first pulsating production line in the world's aviation manufacturing field.
"Actually, it's not a new concept."
Zhang Xingyang is not particularly excited, after all, if you really want to talk about the pulsating production line, there are actually some precedents in other fields.
It's just that in the field of aviation manufacturing, no one has officially proposed it yet.
"We did the same with car production when heavy industry was underdeveloped."
"If you can't establish a continuous flow production line, then reduce the manufacturing requirements and partially use flow assembly."
Song Tianxing is not a young man anymore, he has naturally experienced all kinds of manufacturing in the previous years and understands this history.
"Moreover, we can also iteratively upgrade the production line in the future, and adopt modular transfer of most parts to improve the efficiency of the production line."
Modular production is still a concept that has just emerged at this time, but everyone is researching, so Song Tianxing also has some understanding.
"Modular production efficiency can be improved, but it requires adjustments to the entire assembly line, and the time and manpower required is not a small number."
"Chengfei currently doesn't have so much money to transform the production line."
While the idea is beautiful, it takes a lot of money to turn it into reality.
"Now the export of Chengfei aircraft is not very smooth, and everyone in the world is pursuing the replacement of third-generation aircraft."
"Like the Jian-7, which has been constantly exporting to earn foreign exchange in previous years, it has not been able to sell internationally in recent years."
Song Tianxing kept talking about the current difficulties of Cheng Fei, and he was a little worried about the funds.
"The problem of funding is indeed a relatively big problem, but if Cheng Fei really wants to build a pulsating production line, the country and the Air Force are not expected to be stingy with allocation."
"After all, if the pulsating production line is built, the production efficiency can be increased by four or five times."
"One production line can produce at least 100 J-10 every year, I don't believe those bigwigs in the Air Force are not impressed!"
"As long as you disclose this news to them, I don't think you need to look for money, the bigwigs will take the initiative to ask for money from the country!"
Zhang Xingyang has a different view, and the Air Force's desire for advanced fighters has reached the point of almost hunger and thirst in recent years.
As long as a large number of Jian-10 fighters can be given to them, Zhang Xingyang has no doubt that they can even make trouble at the top.
At this time, Song Tianxing also somewhat understood what Zhang Xingyang meant, and said:
"Also, after knowing the success of our J-10's first flight, several air force chiefs asked when they would be able to mass-produce equipment troops."
"If they knew that they could produce hundreds of aircraft a year, they would probably push this thing forward anyway!"
