"hiss……"

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

It seems that's really what happened.

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

After all, through the previous training of the 601rd Project, both the 112st Institute and the th 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's no shame in finding foreign aid.

Don't ask, even the turbofan 10 has done the job.

Do you understand what a control variable is?
Chang Haonan, who was standing next to him, was just watching the excitement, but the topic was suddenly brought to his head. Upon seeing this, he quickly waved his hand:

"Although the Aerospace Power Group will soon become 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 general framework of cooperation."

"Strictly speaking, Jiang Zhong is not a company in the aviation industry. Producing fuselage parts for Factory 112 is a normal business practice. 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 the aerospace engine to be independently developed independently of the main engine model, and by the way, it could also reduce unnecessary work to a certain extent. Resources are invested repeatedly.

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

After all, judging from future experience, with the exception of the aerospace industry and the weapons industry, all other fields that have undergone parallel splits, such as aviation, shipbuilding, railways, etc., have been re-merged after going through some twists and turns.

But now, it seems that 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 Aviation Development Group just happened to be mentioned again, so He Ming took advantage of the situation and changed the subject:
"After the official establishment of the Aviation Development Group, the Turbofan 10 project should be considered a successful start, right?"

Chang Haonan raised his head slightly, thought for a moment and replied:
"According to the current timetable, 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 Development Group should be the turbojet 6D..."

Although he has not been officially included in the aviation power group's preparatory team, he is still one of the future team members, so he naturally knows something about these things.

He Ming was stunned when he heard this model:
"Turbojet 6D?"

Of course he knows about the Turbojet 6, it is the power of the J-6 after all.

For most of He Ming's generation of Factory 112 workers, the first model they were responsible for after joining the work was the J-6 and its improved versions.

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 would have almost forgotten that there is such a plane..."

"There have been so many good news in the past few years, almost one after another. It always feels like those old models were a long time ago..."

"A strong 5... It is true that it has fallen behind the times in all aspects, and the last improved version that was equipped in batches for troops was indeed a version more than ten years ago."

Chang Haonan agrees 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, in the past two years, the operation of the aviation power side has become relatively independent, so we have retained the turbojet 6D model in the name of self-raised funds by the research and development unit. We should also be doing dual-engine installation tests at present, but the progress It’s much faster than Taihang’s, after all, it’s just a limited improvement.”

He Ming had 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 Turbofan 10... A good start depends on influence. Even if Turbojet 6D progresses faster, it has symbolic significance for a newly independent deputy first-level central enterprise like Aviation Power. The Turbofan 10 is still bigger.”

"Different."

Chang Haonan shook his head:

"The influence of the turbojet 6D itself is indeed not great, but it is the first aeroengine project in our country that continued to develop and finalize the design even though the corresponding aircraft model has been cancelled. The symbolic significance of this is The aviation power group attaches great importance to it.”

After such an explanation, He Ming suddenly became enlightened.

For someone who builds aircraft, no matter whether the project is successful or not, they are always responsible for themselves.

But for colleagues working in aerospace engineering 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 is impossible to say that I am not feeling depressed.

Therefore, in terms of "competing for reputation", 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 but 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 Aerodynamics has not yet been formally established, and Chang Haonan has not yet obtained a key doctorate degree, the appointment of the 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 military training for large-scale battles. 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, if there is a gap, there is room for improvement..."

Just as the three of them were talking to each other, there was already a sound of motor running in the workshop, followed closely 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 naturally 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 and 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, when this project was reported before, it was said to be an improvement on the 80-ton hydraulic press developed by Qinghua University in the 6.8s?" Being able to ask this question right away obviously means that you have seen it before. Relevant technical information.

Come prepared.

"Yes."

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

"Parts such as the hydraulic mechanism, correction system, electrical equipment, sensors and auxiliary equipment have adopted many of the results achieved that year. Otherwise, it would not have been possible to 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 of that forging press. Compared with the one you built, the difference seems to be quite big..."

"Yes, the overall design of the previous machine was the 'orthogonal pretensioning frame' originally invented by Academician Shen, which is a type of prestressed steel wire wound frame."

Faced with a leader who asked such detailed questions, Chang Haonan had no choice but to brace himself to respond:

"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 2 tons. If we want to apply it to the level of 7.5 tons, there are too many problems that need to be solved, and they are all It is a relatively weak technical field in our country.”

“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 7.5 tons, but the design goes a step further, making the entire machine The equipment has improved significantly in terms of stability and predictability. ”

In fact, Chang Haonan was not prepared to take the technical route of wire wrapping the frame from the beginning.

It's just that when he wrote the feasibility report, his 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 wrote the research and development plan for the 6.8-ton hydraulic press. Go in.

Now when the leaders look at 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 it 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 signaled 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, was completed by ourselves."

Chang Haonan replied decisively:
"As for those parts that cannot be produced in China 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 localized replacement in the shortest possible time, or at least backup replacement."

"..."

After a series of questions, the chief, who always maintained a serious smile, 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 final step, right?"

He pointed at a curve on the computer screen and continued without waiting for Chang Haonan or anyone else to answer:

"I can still understand this working cylinder pressure curve."

"Since it's almost over, let's go down and wait..."

The big leader has already spoken, and others naturally have no choice but to follow suit.

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 important occasions.

The first time Anne Colombo walked in here, she was surprised by the several-story-tall piece of equipment in front of her, and she had to raise her head deliberately to see the top.

Although she is considered a technician, she has basically left the front-line research and development 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 hesitantly confirmed to Bernard Ziegler next to her.

As a veteran aircraft designer and aeronautical 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 locations on the fuselage, and the requirements for craftsmanship are even higher than the requirements for the equipment itself..."

“After we bought the 6.5-ton hydraulic press from the Soviet Union, it took nearly three years from the first successful start-up to the forging of large-size products that met the requirements. This was all with the help of Soviet technical personnel. Without guidance, their device itself has not even been verified..."

"I wouldn't say they're definitely not ready, but regardless, there's no reason to be too optimistic right now."

"But before I came in, I saw the promotional slogans they posted in the factory. They all said that trial production would be held today?"

Thanks to her and her husband's close business ties with China, Anne has also learned some Chinese over the years.

This was Ziegler's first time in China, so it was naturally impossible to understand what those square characters were, but he could also tell that this was the final preparation before production.

However, in terms of his experience, the gap between trial production and actual production...

Still relatively large.

"Ma'am, generally speaking, some relatively simple or even symbolic workpieces will be selected for trial production, such as the simplest, a long strip or a 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 workpieces produced during trial production. It can be said that they are not the same thing at all..."

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, it was not possible to equip automatic translation equipment, and it was impossible to provide an interpreter for every member of the delegation, so the content of the speech could 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..."

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

But that's not important either.

They will have a more detailed discussion session later, so 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 the 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 mid-sentence.

Because what he saw was not a steel plate.

But it is an obvious aircraft partition.

Just not from a passenger plane.

But it should be a fighter...
