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

It seems that this is really the case.

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

After all, through the training of the previous 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 looking for foreign aid.

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

He Ming was stunned when he heard this model:

“Turbojet 6D?”

He Ming scratched his scalp, with a hint of sadness in his tone:

Just as the topic of the Aviation Development Group was mentioned again, He Ming took advantage of the situation and changed the topic:

“After the official establishment of the Aviation Development Group, turbofan 10 should be regarded as a project that has achieved a good start, right?”

"no the same."

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

“strong 5…”

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.

Do you understand what a control variable is?

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:

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 want to strengthen the 5D model in the end.”

Chang Haonan explained.

But for colleagues who are engaged in aviation development next door, it often happens that the research and development work is going smoothly, but because the installed model is no longer available, or the positioning of the installed model changes, the project fails or is repeated.

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

But now, it seems that the host and power have formed some kind of healthy competition.

But it should have been discontinued for more than ten years.

Of course, as a target for others to win over, it is not easy for him to say much on this matter.

So in terms of "competing for reputation", the Turbojet 6D is even on the same level as the Turbofan 10 in a sense.

For someone who builds airplanes, whether the project succeeds or not, they are ultimately responsible for themselves.

It is impossible to say that I am not feeling depressed.

“So strictly speaking, the first completed project after the establishment of the Aviation Development Group should be the turbojet 6D…”

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.

"How can the influence of such a small project be compared with that of Turbofan 10... A good start is about influence. Even if Turbojet 6D progresses faster, for a newly independent deputy first-level central enterprise like Aviation Power, the symbolic significance is still The Turbofan 10 is still bigger.”

“Ah...it's the power of strong 5D.”

“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 recent years, almost one after another. It always feels like those old models were a long time ago..."

Chang Haonan shook his head:

“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.”

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.

"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.

Since Chang Haonan said so himself, it is naturally impossible for the other two to continue on the previous topic.

“Strictly speaking, Jiang Zhong is not an enterprise in the aviation industry. Producing fuselage parts for Factory 112 is a normal business practice. Don't over-interpret it..."

"However, the operation of the aviation power side has become relatively independent in the past two years, so we have retained the turbojet 6D model in the name of self-funding 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:

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

Chang Haonan raised his head slightly, thought for a moment and replied:

“According to the current timetable, if nothing else happens, the design of the Taihang project should be finalized next year.”

“So Mr. Chang…”

It belongs to the willow tree that has been planted unintentionally to form a shade.

“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.”

Because Aerodynamics has not yet been formally established, and Chang Haonan has not yet obtained the key doctorate degree, the appointment of the chief planner has not yet been announced.

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 over there so clearly, you should be... going to work there?"

“By the way, Mr. Chang.”

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 massing the whole country to conduct military training. In terms of the comprehensive development level of aviation development, our country is still far behind the aviation powers. 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 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 Beijing and the European delegation that had just finished their trip to Luzhou arrived in Jiangzhong, Chang Haonan had already prepared everything.

When a big leader comes in person, the first thing to do 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 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 improved on the 68,000-ton hydraulic press developed by Qinghua University in the 1980s?" Being able to ask this question right away obviously means that you have seen it before. Relevant technical information.

Come prepared.

“That's right.”

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 leader lowered his body slightly and looked at the drawings in front of him carefully:

“Before coming here this time, I took a look at 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 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 we 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 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 75,000 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 winding 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 68,000-ton hydraulic press. Go in.

Now when 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 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 ourselves?”

The chief 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 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, 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 to a curve on the computer screen, and without waiting for Chang Haonan or anyone else to answer, he continued:

“I can still understand the pressure curve of this working cylinder.”

“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 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.

At about 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 65,000-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. guidance, and their device itself has not even been verified..."

“I wouldn't say they're definitely not ready, but in any case, 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 the fact that both she and her husband have close business ties with China, Anne has also learned some Chinese over the years.

Since this is Ziegler's first time in China, 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 his experience, the gap between trial production and actual production...

It's still relatively big.

“Madam, 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:

“And the structure of the aircraft bulkhead is much more complicated than the workpieces produced in the trial. 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, there is no condition to configure 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.

“I spoke a little fast, maybe it was 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 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 rose slowly.

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 lifted into the air.

“You see, just like I just said...”

Ziegler stopped abruptly mid-sentence.

Because what he saw was not a steel plate.

It is an obvious aircraft partition.

It's just not a passenger plane.

It should be a fighter...
