Chapter 730 Fighting between left and right
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 presses. equipment companies.
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 65,000-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.
The 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 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 point of view, 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 day by day. For this reason, he has repeatedly proposed to expand the scale of the Toulouse factory, but he has been kicked off the ball constantly, until now. Nor was an explicit permission given.
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 hope the next trip will bring us more surprises."
......
At the same time, in Jiangcheng, Chang Haonan is 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 is not necessarily limited to October. Some units will even start after entering 1999.
As for the preparation content...
Of course it is 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 maintenance, pressure relief, return, and stop. The entire production process can be as fast as several seconds. It can range from an hour to more than ten hours, and the whole process is 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 The laptop and a large pile of paper materials were carefully placed on the table:
"Originally we planned to calculate the results in about 3 months. Even after changing the algorithm, it was originally expected to take two months. Or so, but in actual calculation, it only took a month. Not only did I calculate the parameters, but I also optimized them. ”
"Hey...Actually, this is not entirely due to the algorithm."
Chang Haonan waved his hand towards him:
"The main thing is that I have to fight with the Institute of Computing Technology. I said hello and increased the allocated computing power. Otherwise, even if the algorithm is changed, it would not be possible to produce so much quickly..."
"So that's what it is?"
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 a blue overalls, also came from When I came back from the workshop, I happened to overhear the chat between Chang Haonan and Chang Haonan, so he continued: "There is no way, our factory needs this partition frame very urgently, and the key superior leaders have concentrated the technical staff to ten Project No. 1 is over there, and we still hope to take out the heavily modified B model prototype within this year."
He took off his helmet and hung it on the coat rack by the door. on the machine, and then sat next to the console together, watching the equipment operator input operating parameters one by one.
"Indeed, it is similar to our project. It is also an opportunity to give a gift to the National Day."
Lin Jingtang said without looking back while checking the parameters on the computer.
But why Ming shook his head:
“The Type B aircraft of Project 11 will definitely not be able to make the National Day gift. Even if it can make its first flight within the year, it will only be in November or December. Besides, we have been With the help of Mr. Chang, giving gifts has almost become a daily routine, and this model is not bad.”
“The key is that in the past, we have always built the aircraft and then waited for others to build it. I sent it on a voyage, but this time..."
Speaking of this, he glanced at Chang Haonan next to him:
"Now that Mr. Chang has taken out the matching engine, our aircraft is still there...and the aviation industry and aviation power are no longer there. It will be split up in two months. Project No. 10 and Project No. 11 are considered 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 the opposite 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 wind tunnel, and the progress will definitely be slower. Therefore, the important task of keeping up with the progress of the turbofan 10 can only fall on the latter for the time being -
In the past, it was always said that the engine was holding back, but now it is being beaten as soon as it is separated. , 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 and looked at He Ming first, 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 what you said, Eddy Fan 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?"
