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

Xie Kai thought about it, the introduction of the bass engine cost 500 million pounds in the seventies, and no matter how tight the state funds are, it is impossible for such a project to be cut off.

Time is needed to come over the industrial system.

J-7 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, "Within three years, we can provide 45,000 tons of large presses;

Both of these things they can provide.

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

"I can't answer this now, and I can't guarantee it, but the big press can be sure that it can be provided in three to four years. Zheng Yucheng really doesn't know when the four-axis CNC machining center will be built.

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

"Actually, there are these, but there are no guarantees. Tian Rui's excitement quickly subsided.

Led everyone to the machining workshop.

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

"We have CNC machine tools from Germany, Switzerland, and the United Kingdom...... The performance is not very good, and most of them are two-axis linkage CNC lathes, three-axis two-linkage CNC milling machines, and there are not many machining centers......" Pointing to the rows of neatly placed CNC equipment, Tian Rui introduced, "They are all small processing equipment, and we need large ones." At present, our large-scale processing equipment is made of 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, the number of parts waiting to be processed is not much.

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

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

"It's very difficult to process the parts here. Due to the high temperature of the engine combustion chamber, the high temperature resistance of the components is also very high. Originally, the superalloys used in our domestic rocket engines were not suitable for them. The British provided the material formulation, but we were unable to produce the material that matched their properties. ”

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

In a word, the British provided a full set of drawings and processes, but because of the process equipment and production experience, the country could not produce according to the technical data provided by the British.

"Didn't the British provide technical personnel to assist?" Xie Kai was curious, after the British exported the technology, what did they help, "Don't they care about the materials or anything?"

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

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

500 million pounds, just buy such drawings, and they are indigestible drawings.

The British are obviously making a big deal out of 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 people asked, they said it wasn't part of the deal. We can't produce qualified products according to the process ourselves, which is our problem, and it has nothing to do with them......"

Xie Kai understood that the British were simply not ready to cooperate with China.

In the 70s, 500 million pounds sterling, the domestic foreign exchange relied on some industrial basic products and agricultural products that were not easy to accumulate.

In this way, the British were deceived by it.

Perhaps, it's not called cheating, people gave technical drawings and production processes, and they couldn't get it out of it themselves.

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

Several people nodded.

It took 30 years for many domestic scientific and technological workers to find out why Qinling Engine has not been able to succeed, and Xie Kai feels that he has found the answer.

"Have you ever looked for Old Man Wu Zhonghua?" Xie Kai asked.

Several people looked at him in amazement.

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

Xie Kai is so young, and there are only a handful.

"The bass engine is designed according to the theory of Mr. Wu, we should ask him to introduce the basic theory to us in detail, and then we will digest it according to the process of theoretical design, so that it is much easier. Xie Kai said.

There was embarrassment on the faces of several people, and they did not answer.

Du Shengfeng gave Zheng Yucheng a look on the side, asking him to stop Xie Kai from continuing to discuss this topic.

"Xie Kai, you have to know that there are some things that need to be nodded from above. Zheng Yucheng understood that since he didn't let the old man get involved, there must be a reason.

"It's not that the old man is not involved, the old man is now the director of the National Institute of Thermophysical Sciences, and he doesn't have much time to stay on our side...... He used to come here often to give lectures, and it was difficult for us to digest his theories because of our technical reserves......"

Li Bingkun was a little embarrassed.

The technical strength reserve of Western Airlines is too poor.

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

Can't say anything.

He thought that Mr. Wu did not participate, and the original problem still appeared in the West Airlines Factory.

"Regarding talents, you haven't considered introducing them?" Zheng Yucheng asked with a smile when he saw that several people were embarrassed.

"How to bring in? How long do college graduates have to be trained to be independent? Tian Rui felt that Zheng Yucheng was completely idle, and it was too painful.

"Go to other units, find a good one, dig it up! Isn't the turbofan-6 all dismounted? Isn't the turbofan-8 project also ...... Forget it, the turbofan-8 is our project, so don't expect to poach people from them. Zheng Yucheng said that he was a little embarrassed.

The turbofan 8 is matched with the Yun 10, and the Yun 10 is their project, and the turbofan 8 will definitely not be able to stop researching.

He actually asked the people of Xihang to dig up their own talents.

If Xie Kai hadn't glared at him, he wouldn't have realized the problem.

"Can this work?" Tian Rui and the others looked at Zheng Yucheng with strange faces.

"What's not to do? Other units are not developing well, they can't eat, and it's not a problem to borrow some people from them, right?" Zheng Yucheng did not do such a thing.

Many of the technical talents in the 404 base came in this way.

"Leaders are not stupid. Li Bingkun felt that Zheng Yucheng was completely joking.

"I'm not kidding. What kind of people are lacking in our base, I'll go and give them Zhang Luo. If the other party doesn't give it, it's easy to say, give some money, and it's done, aren't you short of money......" Zheng Yucheng simply explained.

At present, there is no such thing as a snatch for talent in the country, and even if there is, it is only a university graduate.

404 is different, they don't have time to train college graduates who have just graduated, so they can only find other units to help train them.

"Director Zheng, you won't be interested in our talents, right?" After listening to Zheng Yucheng talk about how to operate, even Du Shengfeng secretly scolded this old guy for being insidious in his heart.

originally thought that Zheng Yucheng and their insidiousness were just a pit for money.

Only now did I find out that this is already bad to the bone.

"If we don't count on your engines to support our new fighter project, your technical personnel will also be within the range of our sugar-coated shells......," Zheng Yucheng said proudly. "If the cannonballs can't defeat them, they will hit you, there will always be some people who will be defeated, not to mention that they are all brother units, they just carry forward their style to support a few people......"

The group even felt that they should stay away from Zheng Yucheng.

"How about our powder metallurgy at present?" Xie Kai saw that Zheng Yucheng was getting farther and farther away, the old guy was shameless, and he had to have face.

Powder metallurgy is the basic industrial technology for the production of key core materials for aeroengines such as superalloys and titanium alloys.

The rocket engine of the 404 also needs to be made out of the blank through powder metallurgy.

"The temperature is not reached, and the holding time is not long enough. In addition, the high-frequency furnace model is too small, and it is powerless for large-scale monolithic parts production. The turbine discs used in the engine are all imported from the UK...... "Returning to the engine-related matters, everyone can't help but become depressed again.

Military special materials such as high-temperature alloys and titanium alloys contain a large number of metal materials with a melting point of up to thousands of degrees, so it is naturally impossible to use traditional steel smelting methods.

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

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

The more top-quality the material, the higher the requirements for such a processing process.

The turbofan eight engine also faced these problems.

If the monocrystalline integral turbine disc cannot be manufactured, the service life can be imagined.

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

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