Rebirth of Military Workers

"We don't need funding, the only thing we lack is the time and the power to digest their technology..." Wang Kunnan said quietly after a long while.

Xie Kai thinks about it. The introduction of the bass engine cost 500 million pounds in the 1970s. Such a project, no matter how tight the state is, it is impossible to stop such a project.

Time is needed to come to the industrial system.

The JH VII is waiting for domestic engines.

"At the same time, we also lack supporting large-scale high-precision processing equipment, such as forging forming machines, high-precision CNC machine tools, etc..." Tian Rui also said.

Zheng Yucheng looked at them, "In three years, we can provide 45,000 tons of large presses; CNC machine tools, how many axis linkage do you need?"

Both are what they can provide.

"Four-axis linkage CNC machine tools, four-axis linkage in the true sense!" Tian Rui said excitedly, "Can you get it? How long can you get it?"

"I can't answer this now, and there is no guarantee. Only the large press can be sure that it can be provided in three to four years." Zheng Yucheng really does not know when the four-axis CNC machining center will be available.

The base has invested a lot in this area, but because it is not a machine tool manufacturer, it has always been developing CNC systems instead of CNC machine tools.

"In fact, there is no guarantee for these." Tian Rui's excitement quickly subsided.

Brought everyone to the machining workshop.

There are a lot of CNC equipment in the workshop, many of them are CNC machine tools similar to the 404 precision machining workshop, and some are even older and look simpler.

"For us, there are CNC machine tools from Germany, Switzerland, and the United Kingdom... The performance is not very good, and most of them are two-axis CNC lathes, three-axis two-link CNC milling machines, and not many machining centers... …” Pointing to the neat rows of CNC equipment, Tian Rui introduced, “They are all small processing equipment, and we need large ones. At present, our large-scale processing equipment are all domestic ordinary machine tools...”

Some core components of the engine, such as turbine discs, are not small in diameter.

Processing is very difficult.

In the production workshop, there are not many parts waiting to be processed.

In front of each equipment, there is a large workbench or parts transfer vehicle, many of which are special-shaped parts.

Xie Kai, Zheng Yucheng and others were visiting the manufacturing process throughout the workshop.

"The parts inside are very difficult to process. Because the temperature of the engine combustion chamber is very high, the requirements for the high temperature resistance of the parts are also very high. Originally, the high-temperature alloys used in our domestic rocket engines used This is not appropriate. The British provided the material formula, but we were unable to produce materials that match their performance."

Tian Rui didn't know whether to explain to Zheng Yucheng and Xie Kai, or to Du Shengfeng.

In a word, the British provided a full set of drawings and craftsmanship, but due to problems with process equipment and production experience in China, they were unable to produce them in accordance with the technical materials provided by the British.

"Didn't the British provide technical personnel to assist?" Xie Kai was curious. After the British exported the technology, what they helped. "Don't they care about the materials?"

"They don't care how we produce, and the technicians they arrange won't tell us where the problem is! British technicians are messing around here!" As soon as he said this, Li Bingkun became very angry." No matter what method we use, they will not give any advice..."

"Isn't the contract specified? This is 500 million pounds!" Zheng Yucheng looked at several people with an incredible expression.

500 million pounds, just bought such a few drawings, and they are still indigestible drawings.

The British are obviously embarrassing the country.

"They say they can sell products, they can sell technology, but they don't sell their heads." Tian Rui said with a wry smile. "When our staff asked, they said that this was not within the scope of the transaction. We were unable to produce qualified products according to the process. This is our problem, and it has nothing to do with them..."

Xie Kai understands that the British are simply not ready to cooperate with China.

At 500 million pounds in the 1970s, domestic foreign exchange was hardly accumulated by relying on some industrial basic products and agricultural products.

In this way, the British were deceived.(Read more @ hotmtlnovel.xyz)

Perhaps, it’s not a lie. People gave technical drawings and production techniques, but they couldn’t make them in China.

"So, the problem we have to solve now is from production design to parts processing and manufacturing, and even material supply?" Xie Kai asked.

Several people nodded.

Why Qinling Engine has been unable to achieve success? It took many domestic scientific and technological workers 30 years to get the news. Xie Kai felt that he had found the answer.

"Have you ever found Mr. Wu Zhonghua?" Xie Kai asked.

Several people looked at him in surprise.

There are not many people in China who know the relationship between Wu Zhonghua and the turbofan-9 engine.

There are only a handful of young people like Xie Kai.

"The bass engine is designed based on Mr. Wu's theory. We should ask him to introduce the basic theory to us in detail, and then we will digest it according to the theoretical design process. This way, it is much easier." Xie Kai said.

Embarrassment appeared on the faces of several people, and they did not answer.

Du Shengfeng winked at Zheng Yucheng and asked him to prevent Xie Kai from continuing to discuss this topic.

"Xie Kai, you have to know that there are some things that require a nod from above." Zheng Yucheng understands that since the old man is not allowed to participate, there must be a reason.

"It's not that the old man is not allowed to participate. The old man is now the director of the National Institute of Thermophysical Sciences. He does not have much time to stay with us... He used to come here to give lectures before, and it is difficult to digest his theory with our technical reserves. ..."

Li Bingkun was a little embarrassed.

The technical reserves of West Air are too poor.

"..." What else can Xie Kai say?

Can't say anything.

He thought it was Mr. Wu that didn't participate, and the original problem still appeared in the West Air Factory.

"As for talents, you didn't consider introducing them?" Zheng Yucheng asked with a smile when seeing several people embarrassed.

"How to bring in? How long does it take for fresh graduates to be trained to be independent? Skilled workers, it will take longer." Tian Rui felt that Zheng Yucheng was just too idle for nothing.

"Go to another unit, find a good one, just dig it over! Didn’t the turbofan-6 all discontinue? Isn’t the turbofan-8 project also... forget it, the turbofan-8 is our project, you just Don't expect to dig people out of them." Zheng Yucheng said afterwards, he was a little embarrassed.

Turbofan 8 is compatible with Yunshi, and Yunshi is their project, so turbofan eight must not stop researching.

He actually asked the people of West Air to dig out their own talents.

If Xie Kai hadn't stared at him, he wouldn't realize the problem.

"This works?" Tian Rui and the others looked at Zheng Yucheng with weird expressions.

"What's wrong? The development of other units is not good, and they can't eat. It's not a problem to borrow some people from them?" Zheng Yucheng did such a thing frequently.

Many technical talents in the 404 base come from this way.

"The leader is not a fool." Li Bingkun felt that Zheng Yucheng was just joking.

"I'm really not kidding. What kind of people our base lacks, I will tell them. If the other party doesn't give it, that's easy to say, give some money, and it's done, don't you lack money..." Zheng Yucheng simply said understood.

At present, there is no robbing of talents in China, and even if there is, they are just college graduates.

404 is different. They don't have time to train fresh graduates, so they can only find other units to help train them.

"Director Zheng, you won't be bothered by our talents, are you?" After hearing Zheng Yucheng's explanation of how to operate, even Du Shengfeng was secretly scolding this old guy for insidiousness.

I thought that Zheng Yucheng's insidiousness was just to swindle money.

Only now I discovered that this is already broken to the bone.

"If you don't count on your engines for supporting our new fighter projects, your technical talents are also within the range of our sugar-coated shells..." Zheng Yucheng said triumphantly. "Cannonballs can't knock them down, just hit you. There are always some people who will be knocked down. Besides, they are all brothers. They are just supporting a few people with their style..."

The group felt that they had to stay away from Zheng Yucheng.

"How about our powder metallurgy at the moment?" Xie Kai saw Zheng Yucheng pull further and further away, the old guy was shameless, and he had to make a face.

Powder metallurgy is the basic industrial technology for producing key core materials for aero-engines such as high-temperature alloys and titanium alloys.

The 404 rocket engine also needs to be produced through powder metallurgy.

"The temperature cannot be reached, and the pressure holding time is not long enough. In addition, the high-frequency furnace model is too small, and there is no way for the production of large-scale integral parts. The turbine discs used in the engine are imported from the United Kingdom..." With regard to engine-related matters, everyone couldn't help but become depressed again.

Military special materials such as superalloys and titanium alloys contain a large number of metal materials with a melting point of thousands of degrees, so the traditional steel smelting method is naturally useless.

Powder metallurgy, which is also the world's top material processing technology.

Under the ultra-high temperature and ultra-high pressure environment, various metal materials that were originally powders are squeezed and sintered together, and finally the purpose of forming is achieved.

The more top-level materials, the higher the requirements for such processing technology.

The turbofan eight engine also faces these problems.

If the monocrystalline monolithic turbine disk cannot be manufactured, the service life can be imagined.

"It seems that our missile engine also needs this?" Zheng Yucheng asked Xie Kai.

Xie Kai nodded, "That's a small problem. The missiles need small engines, and the engine runs for only a few seconds or more than ten seconds."
