Chapter 731 A gift for National Day! (4K)
"Hiss..."
When Lin Jingtang said this, He Ming suddenly felt...
It seems that this is really what happened.
Originally, Chang Haonan did not directly participate in Project No. 11, including subsequent improvement projects.
After all, after the training of the August 3rd Project, both the 601 Institute and the 112 Factory have accumulated a group of technical personnel with relatively strong combat effectiveness.
As a result, when it comes to first-tier suppliers, they still haven’t escaped Chang Haonan’s shadow.
However, regarding this matter, He Ming's mentality is still relatively good.
There is no shame in finding foreign aid.
Don’t ask, even the turbofan 10 does the job.
Do you understand what a control variable is?
Next to me, Chang Haonan was just watching the fun, but the topic was suddenly brought to his head. Upon seeing this, he quickly waved his hand:
"Although the Aviation Power Group will soon be Although we are independent, in the final analysis we are still comrades in the Science and Technology Commission system. Even if there is competition, it should still be carried out within the framework of cooperation."
"Strictly speaking, Jiang Zhong is not here either. It is a company that is completely in the aviation industry. Producing fuselage parts for Factory 112 is a normal business behavior. Don’t over-interpret it..."
In fact, it was originally proposed to split the aviation industry according to business differences. At that time, Chang Haonan's idea was simply to enable aerospace engines to be developed independently of the host model, which would also reduce unnecessary duplication of resources to a certain extent.
As for competition, it was weakened as a non-important factor in the original plan.
After all, judging from future experience, except for the aerospace industry and the weapons industry, all other fields that have been parallelly split, such as aviation, shipbuilding, railways, etc., have been merged back after going through some twists and turns. .
But now, looking at it, the host and power have formed some kind of healthy competition.
It belongs to the unintentional planting of willows and willows.
“By the way, Mr. Chang.”
Since Chang Haonan said so himself, it was naturally impossible for the other two to continue on the previous topic.
The topic of the Aviation Development Group just happened to be mentioned again, so He Ming took advantage of the situation and changed the topic:
"After the formal establishment of the Aviation Development Group, the turbofan 10 should be regarded as a project that has achieved a good start, right? "
Chang Haonan raised his head slightly, and after thinking for a moment, he replied:
"According to the current schedule, if nothing unexpected happens, the design of the Taihang project should be finalized next year."
"So strictly speaking, the first completed project after the establishment of the Aviation Power Group should be the turbojet 6D..."
Although he was not officially included in the preparation team of the Aviation Power Group, after all, it is also the future One of the team members naturally knows something about these things.
He Ming was stunned when he heard this model:
"Turbojet 6D?"
Of course he knew about the Turbojet 6, after all, it is the power of the J-6.
The first model that most of the 112 Factory employees of He Ming's generation were responsible for after joining the work was the J-6 and its improved version.
But it should have been discontinued for more than ten years.
“Ah...it’s the power of strong 5D.”
Chang Haonan explained.
“Strong 5…”
He Ming scratched his scalp, with a hint of sadness in his tone:
“If you didn’t tell me, I almost forgot that there was such a plane...”
“There has been so much good news in the past few years. There are so many, and they are almost one after another. I always feel that those old models were a long time ago..."
"Qiang 5... It is true that they have not kept up with the times in all aspects, and in the end An improved model equipped in batches is indeed the version from more than ten years ago."
Chang Haonan agreed with He Ming's view:
"Because the Turbofan 9A went relatively smoothly and the J-H 7A will be put into production soon, the army did not pursue the 5D model in the end."
"However, the aviation power side has become relatively independent in its operations in the past two years, so We have retained the turbojet 6D model in the name of self-funding for the R&D unit. We are currently undergoing dual-engine installation testing, but the progress is much faster than that of Taihang. After all, it is only a limited improvement model. "
He Ming showed a smile on his face and said in a relaxed tone:
"How can the influence of such a small project be compared with that of the Turbofan 10... A good start is about one influence, even if the Turbofan 10 is... The progress of Jet 6D is faster, and for a newly independent state-owned enterprise like Aerodynamics, the symbolic significance is still greater than that of Turbofan 10.”
“It’s different”
Chang Haonan shook his head:
“The influence of the turbojet 6D itself is indeed not great, but it is the first in our country to continue research and development even when the corresponding aircraft model has been cancelled, and finally reached the finalization of the design. The aviation engine project, the symbolic meaning of this piece is more important to the Aerodynamics Group.”
After such an explanation, He Ming suddenly became enlightened.
For him as an aircraft builder, no matter whether the project is successful or not, they are always responsible for themselves.
But for colleagues working in aviation development next door, it often happens that the research and development work is going smoothly, but the project fails or is repeated because the installed model is missing or the positioning of the installed model changes.
It's impossible to say that I don't feel depressed.
So in terms of "competing for publicity", the Turbojet 6D is even on the same level as the Turbofan 10 in a sense.
Of course, as someone who others want to win over, it’s hard for him to say much on this matter.
"So Mr. Chang..."
Lin Jingtang, who had not spoken just now and was just listening to the conversation between the two, suddenly took advantage of this moment of silence to intervene:
"You know the situation there so clearly, you should be... going to work there?"
Because aviation power has not been officially established yet, and Chang Haonan has not yet obtained the key PhD, therefore the appointment of Chief Planner has not yet been announced.
But it’s not really a secret.
So he nodded simply:
"I can't talk about being high, but I do have a position there."
"After all...even if the Turbofan 10 has reached the end of research and development, it is only a model after all, and it has the nature of using the whole country to conduct large-scale battle training. In terms of the comprehensive development level of aviation development, our country is still not as good as the aviation powers." There is a certain gap.”
“From another perspective, there is room for improvement...”
Just as the three of them were communicating with each other, the workshop There was already a sound of motor running inside, followed by a harsh creaking sound.
This is a sign that the die forging press has started to pressurize.
The empty load experiment has been completed before, and whether the trial production task can be successful depends on the next few hours.
...
One week later.
When leaders from all walks of life from the capital and the European delegation that had just finished their trip to Luzhou arrived in Jiangzhong, Chang Haonan had already prepared everything.
When the big leader comes in person, the first thing is to visit.
And they are visited separately.
The members of the European delegation are knowledgeable, but as foreigners, they must not be allowed to run around casually. They can just stay in the forging workshop and watch the excitement.
Domestic leaders and guests can leave as they please, but most of them are laymen who can only understand that this is a very large and powerful equipment, so they can just stay in the forging workshop and watch the excitement.
Only for knowledgeable leaders, the seemingly ordinary screens and parameters in the control room are more attractive than the equipment itself.
The chief raised his hand, pushed up his black-rimmed glasses, and asked Chang Haonan who was following him.
“I remember that when this project was reported before, it was said to be an improvement on the 68,000-ton hydraulic press developed by Qinghua University in the 1980s?” Being able to ask this question right away is obvious. It means that I have read the relevant technical information a long time ago.
Come prepared.
"That's right."
Chang Haonan took a deep breath and calmed down a little:
"Such as hydraulic mechanisms, correction systems, electrical equipment , sensors and auxiliary equipment, many of the results achieved back then would not have been put into trial production in such a short time. ”
After hearing this answer, the chief lowered his body slightly and looked at the drawings in front of him carefully::
"Before coming here this time, I went to see the design plan of the forging press, and I will tell you Compared with the one we built, the difference seems to be quite big..."
"Yes, the overall design of the previous one used the original 'orthogonal pretensioning frame' created by Academician Shen. ', it can be regarded as a kind of prestressed steel wire wrapped frame."
Faced with the leader who asked such detailed questions, Chang Haonan had to work hard to deal with it:
"However, During the research and development process, we found that this kind of frame is more suitable for small and medium-sized die forging presses below 20,000 tons. If you want to apply it to the level of 75,000 tons, there are too many problems that need to be solved, and they are all compared with those in my country. Weak technical areas ”
“So, when determining the overall design plan, we finally chose a C-shaped plate structure rack. The idea is similar to the two Soviet equipment with the same 75,000 tons, but the design goes a step further, making the entire machine The equipment has made significant progress in terms of stability and predictability.”
In fact, Chang Haonan was not prepared to take the technical route of wire-wrapped racks from the beginning.
It’s just that when he wrote the feasibility report, his personal influence was not as great as it is now. In order to improve the pass rate, he needed to find some projects with solid foundation in the past to endorse, so he put the 68,000-ton hydraulic press The research and development plan has been written in.
Now that the leaders see the drawings with different basic structures, they must understand what is going on.
But Chang Haonan can't directly say in front of others that I just wrote casually to deceive you. In fact, I had other plans...
That would be a bit too outrageous.
Some things are just tacitly understood.
"The industrial control system of this equipment was also developed by us?"
The leader motioned to put down the drawings in front of him and looked at the operating parameters displayed on the computer screen again.
“Except for some consumables such as hydraulic oil and auxiliary equipment such as electronic components and sensors, the entire equipment, from paper design to engineering implementation, is completed by ourselves.”
Chang Haonan replied decisively:
“As for those parts that cannot be produced domestically for the time being, we are also actively contacting leading companies in related industries. We have held three demand matching meetings so far and strive to produce them in the shortest possible time. "..."
"..."
After a series of questions, the unsmiling leader finally nodded slightly, obviously concerned about the quality of the equipment. The condition is quite satisfactory.
“Looking at the data above, the trial production process should have reached the final step, right?”
He pointed to a curve on the computer screen, and without waiting for Chang Haonan or others to answer, he continued:
"I can still understand this working cylinder pressure curve."
< br>"Since it's almost over, let's go down and wait for a while..."
The big leader has already spoken, and others naturally have no choice but to keep up.
The group of people left the control room in a grand manner and went downstairs to the viewing platform that had been set up in the workshop.
...
Almost at the same time.
The visiting location for high-level delegations from EU countries is located on the other side of the factory building.
After all, we are foreigners, so we still need to physically isolate ourselves on such an important occasion.
The first time Anne Colombo walked in here, she was surprised by the equipment in front of her that was several stories high and required her to raise her head deliberately to see the top.
Although she is considered a technician, she has basically left the front-line R&D position. Secondly, even before leaving, she was mainly responsible for paper work, so she has never seen the similar equipment in France.
"I think... they might be really ready?"
Anne confirmed with some hesitation to Bernard Ziegler next to her.
As a veteran aircraft designer and aviation engineer, the latter will naturally not be deterred by this little fuss:
“You can’t say that yet,”
He shook his head slightly:
“Just having one piece of equipment can’t prove anything. There are many large-sized forgings in key positions on the fuselage, and the requirements for the craftsmanship are even higher than the requirements for the equipment itself...”
“After we bought the 65,000-ton hydraulic press from the Soviet Union, it took nearly three years from the first successful startup to the forging of large-size products that met the requirements. With guidance from Soviet technicians, and the device itself hadn't even been proven yet..."
"I wouldn't say they were definitely not ready, but in any case, not yet. The reason is too optimistic. "
"But before I came in, I saw the promotional slogans they posted in the factory, and they all said that trial production would be started today?"
Thanks to her and her husband's close business ties with China, Annie has also learned some Chinese over the years.
This is Ziegler's first time in China. Naturally, it is impossible to understand what those square characters are, but he can also tell that this is the final preparation before production.
However, in terms of his experience, the gap between trial production and actual production...
is still relatively large.
"Madam, generally speaking, some relatively simple or even symbolic workpieces will be selected for trial production, such as the simplest, a long or semi-circular steel plate."
< br>
Ziegler looked at the hydraulic cylinder that had begun to slowly reset, and explained to Anne next to him:
"The structure of the aircraft partition frame is much more complicated than the workpieces produced in the trial. It can be said that it is not at all The same thing..."
While the two were chatting, the leaders and guests on the other side had also finished taking their seats, and a host began to introduce the general process of today's trial production ceremony.
In this era, there is no condition to install automatic translation equipment, and it is impossible to provide an interpreter for every member of the delegation, so the content of the speech can only be briefly explained.
“Can you understand what the people on the stage are saying?”
Ziegler asked.
"The speed of speaking is a bit fast. It probably means to celebrate the 50th anniversary of the founding of their country or something..."
Anne is not a Chinese major after all, and the information she can understand is not even as good as the one she just translated. Rough version provided.
But that’s not important.
They will have a more detailed discussion session later. If you have any questions, just ask them then.
After some speeches and celebrations, the loading beam of the forging press finally slowly rose.
The workpiece produced during trial production was slowly pulled out from between the upper and lower beams under the traction of two crane arms, and then rose into the air.
"Look, just like I just said..."
Ziegler stopped abruptly mid-sentence.
Because what he saw was not a steel plate.
But it is an obvious aircraft partition.
It’s just not from a passenger plane.
It should be a fighter jet...
