Chapter 731 A Gift to National Day! (4K)

"Hiss..."

After Lin Jingtang said this, He Ming suddenly felt...

It seems to be true.

Originally, Chang Haonan did not directly participate in Project No. 11, including the subsequent improvement projects.

After all, after the training of the previous Project 83, 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 came to the first-tier supplier, they still could not escape the shadow of Chang Haonan.

However, He Ming's mentality on this matter is still relatively good.

It's not shameful to seek external assistance.

Don't ask, the question is that the WS-10 was also done.

Do you understand what control variables are?

Chang Haonan, who was standing next to him, was just watching the fun, but the topic was suddenly brought to his head. Seeing this, he quickly waved his hand:

"Although the Aviation Power Group will soon be independent, after all, it is still a comrade in the system of the Science and Technology Commission. Even if there is competition, it should still be carried out under the framework of cooperation."

"And Jiangzhong is not strictly speaking an enterprise in the aviation industry. Producing fuselage parts for Factory 112 is a normal business behavior. Don't over-interpret it..."

In fact, when it was first proposed to split the aviation industry according to business differences, Chang Haonan's idea was simply to allow aviation engines to be independently developed without the main engine model, and to reduce unnecessary resource duplication to a certain extent.

As for competition, it was weakened as a non-important factor in the original plan.

After all, from future experience, except for the aerospace industry and the weapons industry, all other parallel split fields, such as aviation, shipbuilding, railways, etc., have been merged back after some twists and turns.

But now, the main engine and power have formed a kind of benign competition.

It is true that a good thing comes out of an accident.

"By the way, Mr. Chang."

Since Chang Haonan said so himself, the other two naturally could not continue the previous topic.

Just when the topic of the Aero Engine Corporation was mentioned again, He Ming changed the subject:

"After the formal establishment of the Aero Engine Corporation, the WS-10 should be considered a project that has achieved a good start, right?"

Chang Haonan raised his head slightly, thought for a moment and 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 project completed after the establishment of the Aero Engine Corporation should be the WP-6D..."

Although he was not officially included in the preparatory group of the Aviation Power Corporation, he was one of the future team members after all, so he naturally knew about these things.

He Ming was stunned when he heard this model:

"WP-6D?"

Of course he knew about the WP-6, after all, it was the power of the J-6.

The first model that most of He Ming's generation of 112 factory employees 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 the Q-5D."

Chang Haonan explained.

"Q-5..."

He Ming scratched his scalp, revealing a little sigh in his tone:

"If you didn't say it, I would have almost forgotten that there was such a plane..."

"There have been too many good news in recent years, and almost one after another. I always feel that those old models are a long time ago..."

"Q-5... It is indeed out of date in all aspects, and the last batch of improved models equipped to the troops is indeed a version more than ten years ago."

Chang Haonan agreed with He Ming's opinion:

"Because the WS-9A is relatively smooth, the JH-7A will be put into production soon, so the troops finally didn't want the Q-5D model."

"However, the operation of the aviation power has been relatively independent in the past two years, so we kept the WP-6D model in the name of self-raised funds by the R&D unit. At present It should also be doing twin-engine installation tests, but the progress is much faster than that of Taihang, after all, it is just a limited improvement. "

He Ming smiled and said in a relaxed tone:

"How can the influence of such a small project be compared with that of WS-10... A good start requires influence. Even if the progress of WP-6D is faster, for a newly independent sub-level central enterprise like Aviation Power, the symbolic significance of WP-10 is still greater."

"It's different."

Chang Haonan shook his head:

"The influence of WP-6D itself is indeed not great, but it is the first aviation engine project in our country that continues to be developed when the corresponding aircraft model has been cancelled, and finally reaches the design finalization. The symbolic significance of this is what Aviation Power Group attaches great importance to."

After such an explanation, He Ming suddenly became enlightened.

For him, a person who builds aircraft, whether the project is successful or not, they are always responsible for themselves.

But for the colleagues next door who are engaged in aero-engine, it is often the case that the R&D work is going well, but the project fails or goes back and forth because there is no installed model or the positioning of the installed model changes.

It is impossible to say that there is no frustration in my heart.

So in terms of "fighting for face", the WP-6D is even at the same level as the WS-10 in a sense.

Of course, as the object of others' pride, he can't say much about this matter.

"So Mr. Chang..."

Lin Jingtang, who had not spoken just now and just listened to the conversation between the two, suddenly took advantage of the silence and interrupted:

"You know the situation there so well, you should be... going to be promoted there?"

Because the aviation power has not been officially established yet, and Chang Haonan has not yet obtained the key doctoral degree, the appointment of the chief planner has not been announced.

But it is not a secret.

So he simply nodded:

"It's not a high position, but there is indeed a position there."

"After all...even if the WS-10 has reached the end of its development, it is only a model after all, and it is also a national battle training. Our country still has a certain gap in the comprehensive development level of aeroengines with aviation powers."

"From another perspective, the gap means there is room for development..."

Just as the three of them were talking to each other, the sound of motors running came from the workshop, followed by a harsh creaking sound.

This is a sign that the die forging press has begun 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.

...

A week later.

When the leaders from Beijing and the European delegation who had just finished their trip to Luzhou arrived in Jiangzhong one after another, Chang Haonan had already prepared everything.

The big leader came in person, and the first thing he did was to visit.

And they visited separately.

The members of the European delegation are knowledgeable, but as foreigners, they must not be allowed to run around. They just need to stay in the forging workshop to watch the excitement.

Domestic leaders and guests can walk around freely, but most of them are laymen and can only understand that this is a very large and powerful equipment, so they just need to stay in the forging workshop to 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 leader raised his hand and pushed his black-framed glasses, and asked Chang Haonan who was following him.

"I remember that when this project was reported before, it was said that it was improved on the basis of the 68,000-ton hydraulic press developed by Qinghua University in the 1980s?"

Being able to ask this question right away obviously shows that he has read the relevant technical information a long time ago.

Come prepared.

"That's right."

Chang Haonan took a deep breath and calmed down his mentality a little:

"For example, the hydraulic mechanism, correction system, electrical equipment, sensors and auxiliary equipment have adopted many of the achievements made in those years, otherwise it would not be possible to put them into trial production in such a short time."

After hearing this answer, the leader lowered his body slightly and looked carefully at the drawings in front of him:

"Before coming here this time, I specifically went to see the design plan of the forging press back then. Compared with the one you built, the difference seems to be quite large..."

"Yes, the overall design of the previous one used the 'orthogonal preloaded frame' invented by Academician Shen at that time, which is a kind of prestressed wire winding frame."

Faced with such a detailed leader, Chang Haonan had to be very alert to respond:

"However, during the research and development process, we found that this frame is more suitable for small and medium-sized die forging presses below 20,000 tons. If we want to apply it to the 75,000-ton level, there are too many problems to be solved, and they are all relatively weak technical fields in my country."

"Therefore, when determining the overall design plan, we finally chose the C-type plate structure frame. The idea is similar to the two 75,000-ton equipment in the Soviet Union, but the design has gone a step further, making the entire equipment have a significant improvement in stability and predictability."

In fact, Chang Haonan did not plan to take the technical route of wire winding frame from the very beginning.

It's just that when he wrote the feasibility report, his influence was not as great as it is now. In order to increase the pass rate, he needed to find some past projects with a foundation to endorse, so he wrote the research and development plan for the 68,000-ton hydraulic press.

Now when the leader sees the drawings with different basic structures, he must understand what's going on.

But Chang Haonan couldn't say in front of them that I just wrote it casually to deceive you, and actually had other plans...

That would be too embarrassing.

Some things are better left unspoken.

"Did we also develop the industrial control system of this equipment ourselves?"

The chief gestured to put down the drawings in front of him and looked at the various 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, was completed by ourselves."

Chang Haonan answered 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, striving to achieve domestic substitution in the shortest possible time, or at least backup substitution."

"..."

After a series of questions, the chief, who always maintained a serious expression, finally nodded slightly, obviously quite satisfied with the condition of the equipment.

"Looking at the data above, the trial production process should have reached the last 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."

"Since it is almost over, let's go down and wait for a while..."

The big leader has already spoken, and naturally the others can only follow.

The group left the control room in a mighty manner and went downstairs to the viewing platform that had been set up in the workshop.

...

Almost at the same time.

The visiting location of the EU high-level delegation was on the other side of the factory.

After all, they were foreigners, and they still had to be physically isolated on such important occasions.

The first time Anne Colombo walked in here, she was shocked by the equipment in front of her that was several stories high and required her to look up to see the top.

Although she was also a technician, she had basically left the front-line R&D position, and even before she left, she was mainly responsible for paper work, so she had never seen the same equipment in France.

"I think... they may be really prepared?"

Annie confirmed with Bernard Ziegler next to her hesitantly.

As a veteran aircraft designer and aviation engineer, the latter would not be intimidated by such a small fight:

"That's not the case yet,"

He shook his head slightly:

"Just having one piece of equipment doesn't prove anything. There are many large-sized forgings in the key positions of the fuselage, and the requirements for the process are even higher than those 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 start-up to forging large-sized products that met the requirements. This was under the guidance of Soviet technicians, and their equipment itself has not even been verified..."

"I won't say they are definitely not ready yet, but in any case, there is no reason to be too optimistic now."

"But before I came in just now, I saw the propaganda slogans they posted in the factory, all saying that trial production will be carried out today?"

Thanks to the close business ties between her and her husband and China, Annie has learned some Chinese over the years.

This is Ziegler's first time in China, so it is naturally impossible for him to understand what those Chinese characters are, but he can also see that this is the final preparation before production.

However, in his experience, the gap between trial production and actual production is still quite large.

"Madam, generally speaking, trial production will choose some relatively simple, even symbolic workpieces, such as the simplest, a long strip or semicircular steel plate."

Ziegler looked at the hydraulic cylinder that had begun to slowly reset and explained to Anne next to him:

"The structure of the aircraft bulkhead is much more complicated than the workpiece produced by trial production. It can be said that it is not the same thing at all..."

While the two were chatting, the leaders and guests on the other side had already taken 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 configure automatic translation equipment, and it is impossible to provide a translator for each member of the delegation, so only a general explanation of the speech can be given.

"Can you understand what the person on the stage is saying?"

Ziegler asked.

"The speed of speech is a bit fast. It probably means to celebrate the 50th anniversary of the establishment of their country..."

After all, Anne is not a Chinese major, and the information she can understand is not even as good as the general version provided by the translator just now.

But this is not important.

They will have a more detailed discussion later, so if you have any questions, just ask them then.

After a speech and a celebratory operation, the loading beam of the forging press finally rose slowly.

The trial-produced workpiece was slowly pulled out from between the upper and lower beams under the traction of two crane arms, and then lifted into the air.

"You see, just like I just said..."

Ziegler stopped talking halfway.

Because what he saw was not a steel plate.

But an obvious aircraft partition frame.

But it was not for a passenger plane.

It should be a fighter plane...
