The military-industrial scientific research system of the academic master.

As the leader of the Airbus delegation, Bernard Ziegler certainly knew that after finishing his trip to Luzhou, he would also go to Jiangcheng to visit a company that produces and operates heavy-duty forging equipment.

In fact, they even applied for the second trip themselves.

Just to take a look at China's technical level in the field of forging technology.

But both Ziegler himself and the technicians who applied at the time wanted to hand over the production of some non-important components to China first.

This is not because they deliberately obstructed it. The main reason is that the French themselves have a 6.5-ton heavy-duty die forging hydraulic press imported from the Soviet Union, and they have a very intuitive understanding of the technical difficulty of forging and producing large-size components.

Let’s not talk about whether China’s equipment can meet the standards.

Even if there is a mature equipment, it does not mean that it can be put into production immediately.

A 10,000-ton hydraulic press is not a punch press used in small workshops. It can be operated by just learning.

Even if different equipment wants to produce the same parts, the process parameters will be different.

Even if they want to teach, they are unlikely to be able to learn it in a short time.

Of course, as a technician, no matter what he thinks in his mind, Ziegler is still relatively cautious in his stance and will leave himself sufficient escape routes.

And more importantly, from his perspective, he actually hopes that this Asian assembly center can be completed and put into production earlier.

First, the cost of production in Asia and sales in Asia will indeed be lower, which will also help Airbus continue to expand the Asian market by taking advantage of the momentum of the previous two years.

Secondly, as the number of orders continues to increase, the production pressure on the factory in Toulouse is also increasing. For this reason, he has repeatedly proposed to expand the scale of the Toulouse factory, but he has been repeatedly kicked, and until now he has not received a clear permission. .

The construction of a new production line will also help to force the local area to improve efficiency.

Therefore, he just nodded calmly:

"Then, I look forward to the next trip bringing us more surprises."

……

At the same time, in Jiangcheng, Chang Haonan was also making final preparations before trial production of the die forging press.

Under the ceiling of the factory building, even banners celebrating the 50th anniversary of the founding of the People's Republic of China have been hung.

Although it is only late May, giving gifts for National Day does not necessarily have to be limited to October. Some units will even start after entering 5.

As for what to prepare...

Naturally, we need to go through the entire production process.

Although it is presented as a "trial production", the basic processes of a heavy-duty hydraulic press include six: fast forward, pressurization, pressure maintaining, pressure relief, return, and stop. The entire production process can take anywhere from a few hours to more than ten hours. hours, and the whole process was accompanied by strong noise and vibration. The two steps of pressure relief and return are even more dangerous...

In short, it is impossible for leaders and guests to watch the entire process on site.

You must complete the first few steps in advance, wait until the ceremony begins, take the product out of the forging press, and celebrate at the end.

What Chang Haonan and the others are doing now is to test the feasibility of the entire production process according to the process parameters of the J-11B fuselage frame.

"Mr. Chang, the new functional processing method you came up with before, we tested it, and it is indeed much more efficient than before."

Lin Jingtang walked into the control room from outside the door, holding a laptop and a large stack of paper materials in his hands, and then carefully placed them on the table:

"Originally, we planned to calculate the results in about three months. Even after changing the algorithm, we originally expected it would take about two months. However, in actual calculation, it only took one month. Not only did we calculate the parameters, but we also added extra Optimized again.”

"Hey...Actually, this is not entirely due to the algorithm."

Chang Haonan waved his hand towards him:

"The main thing is that I told the computing institute to increase the allocated computing power. Otherwise, even if the algorithm is changed, it would not be possible to produce so much quickly..."

"So that's it?"

Lin Jingtang was stunned after hearing this:

"I thought there was something wrong with our calculation estimate..."

At this time, He Ming, who was wearing blue overalls, also came back from the workshop. He happened to hear Chang Haonan and his two men chatting, so he continued:

"There is no way. Our factory needs this partition very urgently. The key superior leaders have already concentrated the technical staff on Project 11. We still hope to get the B-model prototype after the major modification within this year. come out."

As he spoke, he took off his helmet and hung it on the coat rack by the door. Then he sat down next to the console and watched the equipment operator enter the operating parameters one by one.

"Indeed, it is similar to our project, and it also happens to be an opportunity to present a gift for the National Day."

Lin Jingtang checked the parameters on the computer and said without looking back,

But He Ming shook his head:

"The Type B aircraft of Project 11 will definitely not be able to make the National Day gift in time. Even if it can make its first flight within the year, it will only be in November or December. Besides, we have almost completed the gift with the help of Mr. Chang over the years. It’s become a daily routine, and this model is not bad.”

"The key point is that in the past, we have always built the aircraft and then waited for others to build the aircraft. But this time..."

Speaking of this, he glanced at Chang Haonan next to him:

"Currently Mr. Chang has taken out the supporting engines, and our aircraft is still there... Moreover, the aviation industry and aviation power will be split up in two months. Project 10 and Project 11 are considered In the first round of cooperation after the separation, if both parties are held back, it will not look good..."

The new plan of the J-10 is contrary to the situation of the J-11B. The internal equipment has not changed much, but the aerodynamic and structural design are so radical that it requires a new round of wind tunnel, and the progress will definitely be slower. Therefore, compared with The important task of improving the progress of Turbofan 10 can only fall on the latter for the time being——

In the past, it was always said that the engine was holding us back, but now we are being hung up and beaten as soon as we separate. No one can afford to lose this face.

However, after hearing He Ming's explanation, Lin Jingtang frowned. After thinking for a while, he raised his head. He first looked at He Ming, then at Chang Haonan, and finally at He Ming, showing a complicated expression.

"Why are you looking at me like that?"

He Ming was a little embarrassed by the look.

"Look..."

Lin Jingtang had also completed the parameter check at this time, so he simply put the computer aside:

"According to you, the turbofan 10 was designed by Mr. Chang."

He Ming nodded.

"But the aircraft bulkheads, equipment and processes we are currently producing were also developed under the leadership of Mr. Chang."

He Ming continued to nod.

"Then isn't this equivalent to... letting Mr. Chang fight with each other?"
