Chapter 565 Vacuum Electron Beam Welding Technology
For Vorontsov, it would be better if he could establish a joint venture with Torch Group like C.B. Ferrari did, but he could also accept it by continuing to engage in technology exchange.
So he nodded, agreeing with the cooperation method proposed by Chang Haonan:
"So, what exchange conditions is Mr. Chang going to offer this time?"
Chang Haonan No more nonsense, just state the requirements:
"I heard that at the Kazan Aviation Factory, there is a vacuum electron beam welding production line, which is the key technology and equipment provided by the Kolomna Factory?"
Vorontsov was stunned, probably not Thinking that the other party would understand these details so clearly.
"Yes, but that production line has not been put into use since 1991, so its current status is average. More importantly, many relevant technical personnel have transferred jobs or even left completely. ”
Kolomna’s vacuum electron beam welding production line is used to weld large-size titanium alloys or lithium aluminum alloys.
Specifically in the Soviet era, only the central main spar of the Tu-160 and An-124/225 could be used.
After the alliance disintegrated, no new aircraft were built for these three models, and the few aircraft that came off the assembly line were assembled using existing parts.
So the production line naturally fell into disuse.
But what Chang Haonan wanted was not that production line.
The manufacturing and installation of vacuum electron beam welding equipment is extremely complex, and it is difficult to dismantle it, transport it thousands of miles to China, and then reinstall it.
So, it is better to consider building a new one directly.
Even if Tu 160 is not available, this thing will be useful in the future.
In the original timeline, the equipment of the Kazan factory was reactivated after not being abandoned for many years.
First, I changed my career directly and used it to produce some pressure vessels, such as rocket fuel tanks.
Later, I managed to survive until Tu 160M resumed production, and then I returned to my old job.
“It doesn’t matter, as long as the technical information is there.”
Chang Haonan waved his hand and said it didn't matter:
"We have cooperated so many times and are old friends. It doesn't hurt if I suffer a little loss this time."
After Project No. 11 and many In the two projects of arc ion plating production line, Shengjing has cultivated a group of talents who are familiar with Soviet technology and understand Russian.
Furthermore, the Torch Group is developing rapidly now. Even if there are some technical obstacles that need to be tackled again, it should not waste too long.
Vorontsov said to you that you are very kind. If you really want to talk about these two technologies, they cannot be considered to be of the same magnitude.
Of course Chang Haonan also knows this.
But since he would make this request, he had already planned it.
So he saw exactly when Vorontsov was about to speak and pushed back what he said:
“Of course, just such an exchange is still a little unfair. "
"So, we are also prepared to show some new sincerity."
Vorontsov was a little uncomfortable when he choked on his words, but it was hard to show it at this time, so he had to signal Chang Haonan to continue.
"Mr. Vorontsov should have heard of our group's TORCH Multiphysics software?"
The other party nodded.
After contacting 601 during Project 11, Sukhoi quickly introduced this numerical calculation software, and was pleasantly surprised to find that it was closely related to the modeling software KOMPAS-3D they developed. Very high match.
“Actually, we are developing a version with more functions and stronger capabilities. The current plan is to only provide it to a small number of users who have a deep cooperative relationship with our group.”
"The only regret is that because this new version of the algorithm is quite special, it runs very inefficiently on ordinary supercomputers..."
"Fortunately, we have also developed a special algorithm with Sugon Group specifically for these special algorithms. Our new equipment, the Sugon-T series computers, can solve this problem to a certain extent and achieve high-precision, high-efficiency, and multi-degree-of-freedom calculations..."
"..."
< br>The so-called new version mentioned by Chang Haonan is naturally the software and hardware bundling sales strategy that he discussed with Academician Li Jie at the National Science and Technology Awards dinner.
But he said it in a different way, and it became a bargaining chip. What is making cards in the void.jpg
Although Vorontsov on the opposite side has had a lot of dealings with Chinese people, he still clearly lacks resistance to this kind of rhetoric.
After thinking about it for a while, he tentatively agreed to this exchange condition.
Of course, he can only be regarded as a middleman. In the end, formal signature authorization from the Kolomna factory is required.
However, judging from past experience, projects approved by import and export companies are rarely rejected.
So, basically they are inseparable.
......
After finishing the PY transaction with Vorontsov, Chang Haonan returned to the workshop.
The technicians from the brother units are still surrounding the multi-arc ion plating production line, discussing each other word by word.
Seeing Chang Haonan reappear, everyone stepped forward and surrounded him.
"Mr. Chang, we just discussed it, and now we have a proposal. I would like to hear your opinion."
One of the older ones became the speaker and said to Chang Haonan:
< br>“I heard from Mr. Zhong Shihong that this production line will not be scheduled for formal mass production in the Liming Factory for a while. At present, it will only carry out some technical adaptation work.”
“ It just so happens that several of our companies have projects that are in urgent need of this high-stability coating technology, and we really can’t wait until the later production lines are completed and put into production.”
“So, can we do it during this period of time? We will pay for it and let Liming Factory help us produce some samples in the form of an order, which can at least be used for testing? ”
Those who can stand here are all veteran comrades with certain experience in the military industry system.
From the acceptance process just now, it is not difficult for everyone to see that although Chang Haonan is not technically from Liming Factory, he has absolute say.
As long as he nodded, it wouldn't be a big problem.
After all, this production line is completely prepared for the turbofan 10 project.
It will still take some time before the turbofan 10 is finalized and transferred to mass production, or even small batch trial production.
"It's okay, that's okay."
Chang Haonan agreed to the other party's request after some thought.
Anyway, workers in Liming Factory also need to familiarize themselves with the production line. Instead of letting them practice with unused parts directly, they might as well help their brother units solve some practical problems.
But then, he added:
“However, multi-arc ion plating is not a universal process. Please report the type of workpieces and coating materials that need to be coated, so that we can The engineer will review it, and if it passes, just place the order directly after returning.”
"It's easy to say, we are just preparing to chromium plate the inner bore of the gun barrel, which is the most common coating requirement..."
The old engineer who just spoke said immediately.
It seems that he should be from the Ordnance Industry Group.
“We are making the gears of the gearbox. The coating is the same as the demonstration just now, which is titanium nitride, but it does not require such high binding energy...”
“Aerospace resin Glass needs to be plated with indium tin oxide on the surface..."
"Engine piston, coated with molybdenum disulfide..."
The voices ringing around made Chang Haonan feel a little dizzy for a moment. It took him a while to finally send these overly enthusiastic and excited technicians to the specialized staff. The section chief responsible for this ion plating production line will make the connection.
However, he did not leave the workshop immediately. Instead, he quietly watched from the side as the number of projects listed on the paper increased little by little.
Then put on the other side.
Put on a new piece of paper...
Probably, this is the scene that I expected to see when I was just reborn.
