Chapter 113 The Commission of Science, Technology and Industry for National Defense wants to listen to my opinion? (2-in-1)
However, some people have expressed certain concerns about such large-scale modifications.
“But... in this case, wouldn’t it be too big a step?”
“Director Ding, although the 1994 standards are indeed incompatible with our aviation industry system. , but after all, it is a national standard that has been officially adopted. If less than two years have passed, would it be inappropriate to completely overturn and establish a new standard? "
People who hold this opinion are also inappropriate. Quite often, 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, the expert who proposed to establish a new standard saw someone refuting it, and directly spoke back:
“This statement is wrong, GJB/Z64-94, including the original formulation The original intention of the previous batch of standards was just 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, we can certainly establish new standards 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?"
Objection Naturally, it is impossible for one party to just choose to cease all activities.
"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 be modified on the basis of 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 1990s 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 more complicated dispute between interests and routes.
China's aviation industry was originally completely derived from the Soviet Union.
But when the time entered the 1980s, 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 1980s and early 1990s, 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 some things with its own characteristics have been developed on this basis.
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 as huge a market as the West. Therefore, after the short-lived glory in the 1960s and 1970s, the Soviet civil aviation industry gradually By the end of the 1980s, except for a few models, it was almost non-competitive.
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 is promising. , the future is promising.
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. host.
Theoretically speaking, the "National Defense" Science and Technology 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 under 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 definitely 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 the 606 Institute, he has no problem in terms of position or position. Considering one's position, it is not convenient to draw one's own conclusions rashly.
“Hu——”
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 is barely related to 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 pretty good. Why did you replace it? Tell me.avi
Now the two sides are not giving in to each other, and they both make sense 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, the 601st Department also played a little trick of psychological suggestion during the test flight of the new J-8-3 plan, allowing Sukhoi Company to Huge concessions were made in the negotiations to introduce Project 11, and consensus was reached at light speed on several items that had been in stalemate for a long time.
According to the agreement, relevant technical data, equipment and personnel will be in place before the end of the year.
The first domestically assembled J-11 fighter jet is planned to roll off the production line before the end of 1997, and the first J-11 fighter jet entirely produced by China except for the engine is planned to roll off the production line before the end of 1999.
But the civil aviation industry also has something to say.
Since the mid-1980s, Shanghai Aircraft Manufacturing Company has assembled 35 MD82/83 aircraft. The level of production, manufacturing and management has improved dramatically compared to the Yun-10 period.
You must know that this is a mainline passenger aircraft of the same level as the Boeing 737. Four of the MD83s 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 532 inspection items after the MD82/83 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 1990s, 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 complies 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 is production, not assembly.
So 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.
McDonnell Douglas is also facing tremendous pressure at this time, so in order to retain the Chinese market, they have given quite good conditions——
Everything is mainly based on Shanghai Flying.
In other words, in addition to the complete engine provided by the United States, from parts manufacturing to final assembly and test flight, to quality control and airworthiness assurance, Shanghai Aircraft takes the main responsibility, while McDonnell Douglas is only responsible for the drawings and parts raw materials.
Just two months ago, in August 1996, the first batch of MD90 parts had started production in the country.
This is a win-win solution no matter how you look at it.
If not for two and a half months later, McDonnell Douglas was suddenly acquired by Boeing.
However, Ding Gaoheng was not cheating and could not predict the future like someone else.
It seemed a bit reluctant to ask him to give Hufei a blow under such a background...
Everyone knew that McDonnell Douglas was in a miserable state.
But according to normal thinking, in the cooperation between McDonnell Douglas and Hufei, the worse the situation of McDonnell Douglas, the better it should be for Hufei.
Boeing's merger with McDonnell Douglas is simply a trip on the coffin of antitrust laws. Therefore, until it was officially announced on December 25, 1996, it was not favored by many people even on the other side of the ocean.
It can only be said that people back then still believed too much in the integrity of the United States... In short, in such a tangle of palms and backs full of flesh, Ding Gaoheng had no choice but to temporarily adjourn the meeting.
Before getting up and leaving the conference room, he gave Du Yishan a look next to him who never said a word.
The latter naturally understood, and after waiting for a few minutes, he also walked out, and went to the director's office upstairs when no one was paying attention.
As soon as he opened the door, he saw Ding Gaoheng sitting behind the desk with a lit cigarette in his hand, but he did not smoke it.
He just stared at the slowly burning cigarette butt with his eyes, his brows twisted into the character "Chuan".
"Mr. Du, what do you think about this matter?"
Du Yishan has quite a lot of experience. He not only presided over the J-7 imitation work at the 601 Institute, but also later flew in Shanghai. Having participated in the research and development of Yun 10, from a standpoint, I can be considered a relatively "neutral" party in the meeting.
And he also has a close relationship with Ding Gaoheng's father-in-law.
"Of course I have an opinion, but there is something I need to explain first." Du Yishan sat on the sofa beside the office and poured himself a glass of water:
"The person who wrote that assessment guide was my student, so I can't guarantee a completely neutral attitude on this matter."
"A student... can a graduate student write such a thing? "
"Not a graduate student." Du Yishan took a slow sip of water:
"Undergraduate student, I will study for a Ph.D. next year."
Ding Henggao's hands shook.
A long piece of cigarette ash fell on the desk.
But he didn't seem to notice, he just looked at Du Yishan on the sofa, as if to determine whether the latter was joking.
"Okay..."
After about a minute of silence, Ding Henggao finally returned to his original expression and put out the almost burned out cigarette in the ashtray:
“But even so, both parties have actually agreed to expand the assessment guide into a standard. Besides, I also believe in Du Laoqian’s vision.”
"My opinion..."
Du Yishan was about to say that he agreed with Liu Zhenxiang's opinion, but then he seemed to think of something else. After hesitating for a moment, he changed the subject and said:
"Director Ding, I I suddenly feel that you should consider listening to Comrade Xiao Chang’s own thoughts.”
“If I were to speak, it would be difficult to tell whether it was the relationship between us or what I said that affected your final judgment. That makes sense."
"But he is just a young man in his early 20s and will not affect your judgment on an emotional level."
Of course, this was meant for Ding Gaoheng. Du Yishan just felt that this seemed to be an opportunity for Chang Haonan to be exposed to a broader stage.
"Comrade Xiao Chang is..." Ding Gaoheng looked a little confused when he heard this title: "Is it your student?"
"Aviation Engine Intake" sent by 624 "Distortion Test and Assessment Method" is the original draft that Chang Haonan produced for Yan Zhongcheng to see, so there is no author's name on it.
"Yes, my name is Chang Haonan." Du Yishan nodded.
"Listen directly to his opinion..."
Ding Gaoheng lowered his head and thought for a while:
"Wait, Chang Haonan..."
"I seem to have seen this name before."
"No surprise, I gave it to you before. It can be said that he played a major role in solving the wing flutter problem of the 603 Institute of Technology's Xinzhou 60 project, as well as the major wing modification of the August 3rd project last month. "
Mentioned Chang Haonan. , Du Yishan's tone became a lot lighter inadvertently.
"He actually participated in the changes to the J-8-3?"
As a key project named by the highest level, the 83rd Project is naturally the focus of Ding Gaoheng's attention.
And the new prototype also boosted the progress of negotiations on Project 11.
“Not only participated, but to some extent, it can be said to have presided over the technical work. If you are interested in more detailed information, you can ask Yang Fenghata.”
In When facing outsiders, Du Yishan never hesitated to praise Chang Haonan.
"Okay, I am worthy of being your disciple of Mr. Du, he is very capable!"
"In this case, it is not a bad idea to listen to this young man's opinion."
Ding Gaoheng nodded. Agree to Du Yishan's proposal.
However, the familiarity with this name just now still lingers in my mind.
"Wait a minute...I remembered"
He stood up and took out a file bag from the cabinet behind him.
After opening it, there was a meeting minutes inside.
"It was mentioned in the work plan of the Ministry of Electric Power Industry when I went to a meeting a few days ago."
Ding Gaoheng quickly turned to the content he wanted to find:< br>
“Now with the development of our country’s economy, the original power grid system has become increasingly overwhelmed. The power consumption situation of residents and industries in major cities is very bad, so the power sector is seeking to transform the power grid.”< br>
"This, "Using Differential Evolution Algorithm to Optimize Water, Fire, Power Systems and Dynamic Environmental Economic Dispatch", was completed by Xu Yang from the Institute of Computing Technology of the Chinese Academy of Sciences, and Chang Haonan from the 601 Research Institute of China Aviation Industry Corporation."
"I think there should be only one Chang Haonan in Institute 601, right?"
"This..."
Looking at the documents in front of him, even Du Yishan was a little dumbfounded.
He also knew nothing about it.
It seems that Chang Haonan shouldn't have time to get involved in research in the field of power grid... right?
The two stared at each other for a few seconds, then decided to put the issue aside for the time being.
"It seems like your student is even more capable."
Ding Gaoheng said, picking up the receiver of a red landline phone on the table and handing it to Du Yishan.
It is best for the latter to make this call.
Soon, the call was transferred to No. 624 in Fucheng.
Yan Zhongcheng used the fastest speed to find Chang Haonan who was extracting data in the control room.
"Xiao Chang, there is a call from the Commission of Science, Technology and Industry for National Defense looking for you."
"Looking for me?"
Now, it was Chang Haonan's turn to be dumbfounded. .
