At present, the problem of production quality is not only present in the space system.

There are serious quality problems in the production of the national manufacturing system, and the quality problems of state-owned enterprises oriented to civilian products are even more serious.

In the area of quality management, there is not enough experience to learn in China.

With the reform and opening up, the country's focus has shifted to economic construction, and the follow-up military production, especially the research and development of new products, is almost all single-piece and small-batch production, which has stricter requirements for the quality management system.

Western countries will not teach advanced experience and technology.

Quality management is also very critical in the production process.

The Soviet production system is different from that of the West, taking the road of mass production by special planes and special lines, and the output of a large number of industrial products is very large, as long as new weapons and equipment are developed, they will be equipped on a large scale, and special production lines will be directly developed after the design is completed and the sample manufacturing is almost over.

Under the large-scale special aircraft and special line production, the quality is easy to control.

Domestic equipment production, because of technical and economic reasons, whether in the scale of production or the design of special line production equipment, etc., is because it cannot be compared with the Soviet Union, but the quality is relatively poor.

Quality control has become more urgent in China after the reform and opening up.

"Teacher, in order to solve the problem of product quality of aviation systems, AVIC 301 is now formulating technical standards and requirements for electronic components...... In this area, we can put forward some more targeted suggestions according to the actual situation of aerospace. In terms of production, it is more appropriate to seek truth from facts and understand the specific situation to formulate a plan...... I was in the 2186 factory, and I found a lot of problems, and the technical department almost did not take into account the actual situation of production when formulating technical solutions......"

Liu Yue made a more detailed report on the situation he encountered in Factory 2186.

He also introduced the various means he used to control quality, and brought the process documents of each link from product design to subsequent production and processing.

It's also part of his homework.

This time I went to the Northeast Low Temperature Range, and took these documents with me,

He had planned to make a trip to the capital on the way back to the base.

"To formulate national technical standards, you must understand the actual situation, and you don't have to worry about that. Dean Qian didn't expect Liu Yue to be so well prepared, and a smile began to appear on his originally angry face.

Mr. Li Pei next to him watched Liu Yue take out a thick stack of drawings, and he didn't look at it, but just looked at the master and apprentice with a smile on his face.

Liu Yue is not doing his job all day long, and when he is doing serious things, he is still very satisfied.

"In this way, can the quality be strictly controlled?" Dean Qian flipped through the information, looking at various quality tracking cards and process documents, in which each process was signed and stamped by operators and inspectors.

All kinds of data, all complete.

Liu Yue nodded, "Teacher, in the actual design and production process of the production line, especially the sample production, from raw material design to process formulation, there are special people in charge. Liu Yue paused when he said this.

Dean Qian didn't interrupt him.

"At present, the two samples produced by our unit are strictly in accordance with such requirements in the production process, and are supervised by special people...... Any size is out of tolerance, does not conform to the theoretical design data, and will be scrapped directly. Although the cost is relatively high, the problem of interchangeability is solved compared to having defective products in the warehouse, or specializing in the production of matching parts......

Interchangeability is very important in the mass production process.

In the Peace Model Project, almost any of the two prototypes sent to the United States for experiments could not be interchanged, and they were used on the other one.

Although, this is in order to prevent Americans from figuring out the real level of domestic manufacturing, some of them are deliberate.

But this can't change the fact that these top equipment in China are produced by hand.

In the field of astronautics, launch vehicles or something, naturally there is no need for mass production, but missiles are different.

The more interchangeable, the easier the logistics and the more reliable the product quality.

Otherwise, if you really fight, you have to send a courier to the enemy, but you deviate by dozens of kilometers or even can't fly, so what's the point?

Quality control is related to the accuracy of express delivery.

If it is not sent accurately, it will be given a bad review.

After all, Liu Yue's express delivery in this field is absolutely not allowed to have bad reviews, express delivery is not allowed to refuse visas, and the nuclear suspension has made the enemy go to hell, and there is no way to evaluate.

Then, the system defaults to a positive review.

"If the equipment with quality problems is finally installed in the troops, the consequences will be serious...... Just like the problem we are encountering now, the production process of 8701 is completely produced according to the formula and process, but the difference between the alkalinity of the northern water and the southern water was ignored before, resulting in the internal corrosion of the explosive, which greatly reduced the power of the rocket...... Even the 200,000 rockets produced before had the problem of reduced power. ”

Liu Yue directly cited the problems encountered by their unit at this stage as an example.

This is not possible if there are well-established standards and the alkaline content of the water is also included in the process requirements.

In the domestic aerospace field, the big man in front of him has a very big influence.

Dean Qian is also very strict about quality control.

Each time, whether it is a test launch of a strategic missile or a launch vehicle, it is preceded by a number of large-scale mass checks.

There are a lot of problems that will be checked each time, so these hidden problems must be solved, and they will not be launched until there are no problems that can be found at all.

Even so, there are still some faults that are not sorted out, resulting in launch failures.

"As long as there are systematic standards, in strict accordance with the standards, all technical data, unless the process is changed, after the finalization, will be strictly in accordance with the technical standards, only in this case, whether single production, or large-scale production, can effectively ensure quality. Liu Yue looked at his teacher nervously.

If the teacher doesn't help, it's going to be difficult.

He can influence his own factory, but it is difficult to affect the entire base.

Affects the entire base, and cannot affect other non-base units.

Whether it is a launch vehicle or a strategic express delivery, this is not something that can be done by one unit.

Mr. Li Pei had been listening to the side, and she didn't know much about professional things, so she didn't interject.

Seeing that the hour hand was already pointing to half past ten, she didn't urge the master and apprentice.

Sitting next to him, he was afraid that the two would quarrel.

"I'll leave the information first, and study and study it carefully," Dean Qian's words made Liu Yue breathe a sigh ......of relief.

He hopes to influence the upcoming 7905 technology protocol through money aging.

This technical agreement is the first military technical standard for the system in China.

In the beginning, it was only for the electronic components of the space system.

Liu Yue hopes to expand to the production of all parts in the entire aerospace field, otherwise, he will have to wait for the 8406 technical agreement.

Of course, it is best to expand to the field of military manufacturing throughout the country, but this will have to wait until the national military standard is perfected.

In the field of ordinary manufacturing, the national standard has not yet been established, and the national military standard is more urgent.

Of course, military standards are also much stricter than ordinary standards.

Only strict standards can ensure the stability of product quality and make the technology develop faster.

"Okay, there's no problem now, Liu Yue will hand in the rest of his homework tomorrow......"

Mr. Li Pei saw that the two were chatting about the same, and signaled that it was time to rest.

Liu Yue has nothing, Dean Qian is busy with work all day.

Today, I was able to have such a little time to check Liu Yue's homework, and Mr. Li Pei called him.

Liu Yue took the paper on guided rocket artillery next to him and handed it to Dean Qian again.

Dean Qian looked at him and was reluctant to take the paper.

"Teacher, I know that you want me to engage in core basic technology research in a down-to-earth and serious manner in the fields that the country needs. Long-range rocket artillery is also very basic...... The domestic technology foundation is poor, and what is needed is not only high-end technology research, but also basic technology research...... I am still young and need more opportunities to learn and practice, and at the same time, I hope to have a team that grows together, and when the foundation is solid, I will invest in high-end research, and the progress will ......be faster."

This is the first time Liu Yue has said his true thoughts in front of his teacher.

Dean Qian looked at Liu Yue in surprise, Liu Yue had never said such a thing before.

Mr. Li Pei smiled with satisfaction: "Liu Yue, your idea is very good. The whole team grows together, promotes each other, learns from each other, and grows faster. But didn't you say that your unit has a weak foundation and lacks technical personnel?"

Dean Qian didn't speak, just looked at Liu Yue.

He knew that Li Pei's words were helping Liu Yue get someone.

"Teacher, the technical strength of my current unit is really poor. The 273 mm multiple rocket launcher project was created in order to integrate the technical strength of the 2186 factory and the 2109 factory, one of which has strong production and manufacturing capabilities and the other has strong design capabilities. Combining the two units will improve a lot. There is not much difference between rocket artillery and missiles in essence, but the difference is in guidance...... Through these small projects, I can continue to design and improve, so that this team can gain rich experience, and I can also grow with my own team......"

Liu Yue paused here and looked at his teacher secretly.

He knew that President Qian hoped that he would do solid research in some fields of strategic missiles or carrier rockets, and even space technology.

Liu Yue also knew that engaging in rocket artillery disappointed the teacher.

There is a big gap between the technology used in rocket artillery and the technology used in strategic missiles and launch vehicles.

The technology used in small missiles is not necessarily used in launch vehicles and strategic missiles.

The technology of the launch vehicle, after optimization, can be used on small rockets.

"Go on......" Qian Lao looked at Liu Yue and motioned for him to continue.

"Whether it is the production line or the research department in the base, many of the fresh blood who entered before are workers, peasants and soldiers. These students have weak basic knowledge and poor foundation, and they have been making up for the foundation for a long time when they are in college, and they don't have much time to learn advanced theoretical knowledge...... Each subject requires a lot of time and a lot of expertise to make better use of ......"
