The military-industrial scientific research system of the academic master.

However, some people have expressed some concerns about such large-scale modifications.

"But... in this case, would it be too big a step?"

"Director Ding, although the 1994 standard is indeed incompatible with our aviation industry system, it is still a legitimate national standard after all. If less than two years have passed, it will be completely overturned and a new standard will be established. Will it be wrong? Is there something wrong with that?"

There are many people who hold this opinion. After the first person came forward, two or three more people expressed similar concerns.

After all, the American standard that GJB/Z64-94 refers to is definitely technologically advanced enough.

On the other side, when the expert who proposed setting up a new standard saw someone refuting, he directly retorted:

"This statement is wrong. GJB/Z64-94, including the batch of standards originally formulated, was originally intended to occupy space. Now that our own aviation industry department has the ability to propose technical guidelines that meet our country's national conditions and needs, of course A new standard can be established on this basis.”

"National standards are intended to unify technical requirements across the country and guide the specific development and implementation of related work. The original 1994 standards did not have this capability, so why can't they be overthrown and started over?"

Naturally, it is impossible for the opposing party to just die down.

"I think there is no problem in expanding the guidelines just now, but in the past ten years, our aviation industry system has been breaking away from the Soviet Union's set of ideas and gradually moving closer to the West. The current standards also respond to this trend. It is an estimate, so it should still be modified based on the 1994 standards."

Ding Gaoheng, who was sitting at the head of the conference table, looked silently at the two groups arguing fiercely in front of him.

It actually did not surprise him that such differences of opinion would arise.

The Chinese aviation industry system in the 90s was already in the process of major changes. The total pressure distortion assessment of aeroengines involved in GJB/Z64-94 was of course only a small part of the aviation industry.

But what is hidden behind it is actually a dispute over complicated lines of interest.

China's aviation industry was originally completely derived from the Soviet Union.

But when the time entered the 80s, the object of our study gradually became the United States on the other side of the ocean.

However, the honeymoon period between the two countries only lasted about ten years. With the end of the Cold War, the Americans, who had lost their biggest rival, once again resorted to the stick of technological blockade.

Therefore, in the late 80s and early 90s, the development direction of the aviation industry had to change to refer to French standards and Russian technology.

Judging from the situation in the past few years, this approach has no problems at least in the military field, and on this basis, some things with its own characteristics have been developed.

The trouble lies in the civilian sector.

Due to the indescribable economic level of the countries in the economic cooperation system, the civil aviation field cannot provide a huge market like the West. Therefore, after the short-term glory in the 60s and 70s, the Soviet civil aviation industry gradually declined. By the end of the 80s , except for a few models, there is almost no competitiveness.

Although the European civil aviation industry, represented by Airbus, is currently in a stage of vigorous development, in terms of overall scale and industry maturity...

The future can be expected, the future can be expected.

Considering the reality of a high degree of monopoly, and the fact that the blockade and sanctions in the civil aviation field did not seem to be that strict, until 1996, China's civil aviation development ideas were still based on following the steps of the United States.

Theoretically speaking, the "National Defense" Science, Technology and Industry Commission, as its name implies, is mainly responsible for managing the national defense science and technology industry, while the civilian science and technology industry should be the responsibility of the National Science and Technology Commission and the Ministry of Machinery Industry.

But obviously, it is impossible for two completely different sets of standard systems to exist within the same industrial category at the same time.

No Indian can do such a thing.

The standard-setting power of China Aviation Industry is undoubtedly in the hands of the Commission of Science, Technology and Industry for National Defense.

In other words, the national military standard set today is basically certain to become the national standard in the civil aviation industry in the future.

Therefore, the Shanghai Aircraft Manufacturing Company, which has made some progress in the civil aviation industry, at least on the surface, is naturally unwilling to give up the 1994 standard that refers to the American standard easily.

The military field has suffered a big loss in the Peace Model Project before, and the current development route is already on the right track, and it certainly does not want to change the technical route.

This is also the reason why Yan Zhongcheng chose to report it directly after seeing the guide written by Chang Haonan——

As the chief model engineer of Institute 606, it is not convenient for him to make his own conclusions rashly, regardless of his position or status.

"call--"

Ding Gaoheng pinched the swollen corners of his eyes and felt a little embarrassed for a moment.

He is an expert in the field of inertial technology and precision instruments. He has some connection with aerospace, but he is not an expert in the aviation industry.

In his research direction, he has not been involved in similar disputes over standard routes.

The Soviet standard is fine. Why did you replace it? Tell me.avi

Now the two sides are not giving in to each other, and both sides have reasons from their own standpoints.

Not to mention the military field, the progress of Project 10 and Project 83 is very gratifying.

Especially the latter, progress has been rapid in recent months. (Chang Haonan, who was in Fucheng, sneezed for no reason)

Last month, during the test flight of the new J-601-8 program, the 3st Department also played a little trick of psychological suggestion, causing Sukhoi to make huge concessions in the negotiations to introduce Project . Several issues that had been deadlocked for a long time The content was all agreed upon at the speed of light.

According to the agreement, relevant technical data, equipment and personnel will be in place before the end of the year.

It is planned to roll off the production line of the first domestically assembled J-1997 fighter jet before the end of 11, and the first J-1999 fighter jet produced entirely by China except for the engine before the end of 11.

But the civil aviation industry also has something to say.

从80年代中期开始，沪上飞机制造公司已经组装了35架MD82／83飞机，生产制造和管理水平相比运10时期有了飞跃性的提高。

You must know that this is a mainline passenger aircraft of the same level as the Boeing 737. Four of the MD4s were even sold back to the United States, and the production quality of Hufei has caused a sensation on the other side of the ocean.

A typical example is that of the 82 inspection items after the MD83/532 rolled off the production line, the pass rate of the final inspection in Shanghai was 95%, while the pass rate of the final assembly of the Long Beach Company in the United States was only 51%.

By the early 90s, Shanghai Aircraft Manufacturing Company had basically formed the assembly and production test flight capabilities of 150-seat passenger aircraft. More importantly, it had also initially formed a quality assurance system that complied with FAA airworthiness requirements.

On this basis, four years ago in 1992, Hufei Company cooperated with McDonnell Douglas to prepare to go a step further and produce at least 40 MD90s in China.

This time it’s production, not assembly.

Therefore, in addition to Hufei Company, Shengjing, Haojing, and Rongcheng also undertake the supply tasks of a considerable part of the subsystems.

This ties together the entire civil aviation industry in China.
