In the military industry that year, the cloud bombs started to wash the ground for monkeys

Lu Xuan spoke to Jiang Jinsong, the chief engineer, in a discussing tone.

At the same time, his eyes scanned all the researchers in Institute 610.

He was taking care of the mood of these people, and he was also warning them.

In the 618 base, don't engage in seniority ranking.

"No problem." Jiang Jinsong assured.

The other researchers nodded similarly.

Then he looked at Simonov again.

Simonov also nodded to indicate that there was no problem.

Such a thing is not difficult for him at all.

When he was at the Sukhoi Design Bureau, he was responsible for the overall work.

Assignment of design tasks, processing of prototype 5.2 spare parts, assembly of the whole machine, test run of the engine...

He almost did all the work of chief engineer and chief designer by himself.

He has been out of work for half a year, and he cannot continue to be idle like this.

"First of all, let's start with the turbofan 6 that you trial-produced based on the turbofan 14 and imitated the F8 engine."

"I've had a rough look at the engine, and I think I have quite a few suggestions to make."

"As for whether it can meet my design requirements, it depends on your processing capabilities."

Simonov immediately went to work.

"Comrade Simonov, just follow your design requirements."

"You don't need to consider the processing cost and processing technology."

Lu Xuan immediately promised that he would let Simonov know.

The processing ability of rabbits is no worse than that of furry bears.

142 Difficulties in manufacturing turbofan 8 engine

With Simonov and his team on board.

The imitation work of F14 is like having wings, and the progress is rapid.

In particular, some key design issues of the turbofan 8 engine were quickly resolved.

In just two months, the design work of Turbofan 8 was completed, and the rest was manufacturing.

Lu Xuan once again devoted his work energy to the trial production of Turbofan 8.

Now production is the key, whether the production problem can be solved.

It is related to whether the imitation F14 can fly into the sky.

It is more related to the success of the first domestically produced third-generation fighter.

Others are not a problem. While using a large number of titanium alloys increases a lot of costs, processing is also a huge difficulty.

From the very beginning, the high temperature and high pressure powder metallurgy manufactures all parts of the engine.

Then to forging, heat treatment, machining, and various processes.

Lu Xuan worked overtime with the front-line technicians to complete it.

Originally, he would have thought that the turbofan 8 engine problem would appear in the assembly process.

After all, in order to ensure performance, the entire engine must ensure assembly accuracy.

For class 21 fan impellers, it is required to ensure that the coaxiality is within two or three wires after assembly.

02 What's more, the current assembly is mainly manual assembly, and automated mechanical assembly does not have much effect at all.

In order to ensure the accuracy, Lu Xuan mobilized all the top eighth and ninth level fitters.

Even if the accuracy of two or three wires cannot be achieved, at least it must be within five wires.

Otherwise, the performance and service life of the engine will be affected.

"Director Lu, it's not that we don't work hard. We use the same tooling and the same method every day, but the quality of the welds produced is inconsistent."

As the most skilled welder, Wang Yongqiang cannot control the processing quality of the weld.

"Have you analyzed the cause of the problem?" Lu Xuan asked with a frown.

"According to our analysis, the argon gas may not be pure enough." Wang Yongqiang said a little embarrassedly.

"The argon gas is not pure enough, so increase the purity. Could there be some problem?" Lu Xuan was speechless.

"We have no solution to this problem, we don't have too strong technology."

"Also, argon is originally a by-product in the process of producing oxygen, and it is not easy to extract..."

Hearing Wang Yongqiang's words, Lu Xuan immediately thought of the possible problem.

"Is it a problem with the pressurized cabin?"

When filling the working chamber with argon, the air inside may not be exhausted.

It's also possible that the workers weren't venting the air out while they were pressurizing outside.

"Tell the oxygen manufacturing plant that the argon must be 99.99 percent pure."

"When the shift is over, the outside air should be exhausted as much as possible."

"Tell them not to skip a single detail because of the cost."

Lu Xuan really had nothing to say, this kind of problem is actually not a big problem at all.

In the final analysis, those old craftsmen are used to saving. In order to save costs, they didn't care about some details.

After Lu Xuan's reminder and strict requirements, the purity of the argon gas has improved a lot, and the welding effect has also improved significantly.

After solving the welding problem, Lu Xuan put his energy into the assembly of the engine.

The difficulty of processing is equally great.

When the technical strength has not been improved, the experience has not been accumulated enough, and the materials have not been developed in place.

It is very difficult to develop machining tools that can improve efficiency in a short period of time.

Under the current circumstances, we can only use time to slowly pile up these parts and products.

Even Yingjiang, which has a strong processing ability, is helpless when faced with titanium alloy processing.

Otherwise, Eagle Sauce will not eventually let F15, F16, and F18 be matched with each other to replace F14.

F14, which uses a large amount of titanium alloy, not only requires high maintenance, but also increases too much processing cost.

However, Lu Xuan has a material formula from the future in his mind, although the knives he makes are not as good as the craftsmanship of later generations.

But it is far stronger than Eagle Sauce and Mao Xiong, and it costs less and is more efficient.

Lu Xuan turned around and found Jia Yiming's Materials Research Center.

Let them develop new materials and produce processing tools as soon as possible.

Producing a fighter jet in this era is not an easy task.

It is also difficult to produce an engine.

Especially the assembly, it gave Lu Xuan a headache.

He's like a firefighter.

Wherever there is a problem, go there to solve the problem.

The power research center and production workshop of the 618 base.

There are not only the technical conditions for the production of turboshaft engines for straight 9.

There are also technical reserves for the production of rockets and even missile engines.

Lu Xuan had to transfer these people to participate in the production and assembly of Turbofan 8.

The turbofan 8 engine has been tracked from the beginning of welding, and the quality requirements have almost reached a strict requirement.

Lu Xuan personally led people to form an expert team to comprehensively track and control the quality, raising the level of manufacturing to a higher level.

"The eagle soaring in the blue sky must be given an absolutely strong heart!"

Lu Xuan kept this sentence on his lips all the time, and told all the researchers and technicians.

"Starting tomorrow, we will assemble the first turbofan 8 engine."

"Whether our fighter planes can fly in the sky depends on our assembly work."

The night before the assembly, Lu Xuan held a mobilization meeting for the Turbofan 8 R&D and manufacturing teams.

Top fitters with an average age of over 50 sit at the front.

Their faces were complicated, some were excited, some were worried, and some frowned.

Whether it is the leaders on the stage or the researchers and technicians in the audience, there is no one who does not feel nervous.

This is the first domestic fighter engine in the true sense.

Moreover, Lu Xuan requested to assemble two at a time for the air experiment platform test.

Once the assembly of the engine cannot meet the requirements.

It will affect the development of the entire fighter project.

Here are the top fitters in the country.

But what they are facing is also the biggest technical challenge in the national manufacturing industry.

"I hope everyone will go all out and try to assemble the heart of our fighter jet in a short time."

"Dakong should be aware that our imitation of the F14 has been basically completed, and we are just waiting for this engine."

Lu Xuan didn't care about putting more pressure on these fitters.

Before the mobilization meeting, Zhao Xingguo mentioned it to his son-in-law with a worried face.

Putting too much pressure on these top fitters will backfire and fail to achieve the desired level.

Lu Xuan said: "Their ability to withstand pressure is far beyond our imagination."

"People's potential only bursts out when they are faced with collapse."

"Mao Xiong and Ying Jiang are also mainly assembled by manpower. They can do it, why can't we?"

In fact, the ninth-level fitters in China are still quite different from the fitters in Yingjiang, Maoxiong, Yishelie and other countries.

This is not because they do not work hard, but because the top parts they have seen, and the experience of top parts equipment, cannot be compared with the top fitters in these countries.

143 Turbofan 8 assembly completed

Human potential can be stimulated, Lu Xuan firmly believes in this.

Among other things, it is an obvious example to say that mushroom bombs were used in China back then.

Even the top nuclear physicist Qian Sanqiang and others were not very clear about how to make mushroom bombs.

However, in just four years, with a blank domestic foundation, the rabbit's mushroom bomb was still successful.

When Eagle Sauce developed the first mushroom bomb, it not only had a solid industrial foundation.

There is also a group of top scientists in the world.

It also took six years to get it out.

The same is true for Mao Xiong, who also spent six years and nine months.

As for the rabbit's house, they have nothing to ask for, and they don't even have a computer.

Relying on the abacus to perform various complex mathematical calculations, he also came up with mushroom bombs.

The older generation of scientists showed great potential when their domestic base was poor and empty.

However, after the reform and opening up, with better conditions and more financial support, instead of the spirit of the past
