Siheyuan: took over the rolling mill and exported gas tanks

Chapter 71 Aircraft turbine engine, Su Chen must be the one who carries out the secret plan!!

On the one hand, Su Chen was ready to make ice crystals by himself, and on the other hand, Su Chen had a batch of technical backbones dug up in other military factories and got the engine design drawings he gave them.

These technical backbones were not valued in military factories before, and the wave of layoffs caused them to lose their jobs.

If it weren’t for the Red Star Rolling Mill’s willingness to take them in, these technical backbones would have starved to death a long time ago.

Therefore, after receiving the task given by Su Chen, they began to study non-stop.

Most of these technical backbones have gray hair, due to perennial brain use, they are not old first, don’t look at their white hair, most of them are only in their early forties.

Several technical backbones gathered around the design table, which was about two meters long and was neatly arranged with tools such as pencils and rulers.

These figures, who were considered technical masters in the factory in the past, looked at each other around the design drawings drawn by Su Chen.

They enlarged the design drawings a lot, hung them on a blackboard on the side, and wrote small notes on every detail.

The original design drawings, which are very complicated, plus the remarks, are like a book from heaven.

This engine design drawing is very detailed, and there is more to it than the main body of turbo engine technology.

A man with almost all white hair gestured at the triangle board in his hand.

“That’s right, this is definitely a wide-chord shoulderless hollow sandwich structure!”

He excitedly held the board and carefully observed the appearance of the blade.

Now the domestic main use is with a shoulder fan structure.

The reason why the fan with a bevel shoulder is used is to solve the accident caused by bird impact and vibration.

This turbine engine is mainly used in aerospace technology, so its peripheral blades are also designed to be able to be used in high altitude.

Although the fan blades can bring extremely high speed and improve the efficiency of the engine, there is another very serious problem is vibration.

Because the fan blades are very long and thin, it will easily resonate during operation, resulting in fatigue breakage.

Therefore, in order to solve this problem, the fan blades of turbofan engines are all made of a bevel design without exception.

The shoulders of each blade are close to each other, forming a ring hoop that strengthens the blade, which not only increases the rigidity of the blade, but also improves the ability to resist the impact of foreign objects, as well as the mitigation of the self-vibration frequency of the blade, and is not easy to vibrate.

However, this design brings many problems, the processing accuracy required for each blade is too high, and the centrifugal adhesion at the blade root will increase.

In order to solve this problem, many foreign large engine companies have thought of ways to cancel the shoulders and widen the blades to make them wide-chord blades.

However, simple widening will cause other problems, although the blades that are too wide are not easy to vibrate, they also have strong resistance to foreign objects.

However, due to its increased weight, the roots will not be able to withstand it, and the disc on which the blades are installed must also be made heavy, which cannot be applied to large aero engines.

Therefore, a foreign company invented a new fan blade design and manufacturing method.

This is the blade of the wide-chord shoulderless hollow sandwich structure.

“This technology has just been invented not long ago, it has been monopolized by the international world, and it is blocked by our country, where did the director get it?”

“With this blade design, we can break through the international blockade and bring a qualitative breakthrough to the aviation industry!”

“Our planes have not been able to increase the power, isn’t it because the engine is stuck in the neck of other countries? This technology is so good! ”

Several technical backbones gathered around to look at the schematic diagram of the blade, and they were full of tears.

The workers on the side who are just laying their hands do not understand how epochal this design is, they only know that these technical backbones are crazy again.

“Intellectuals who study technology are really crazy.”

A worker shook his head as he cleaned up and collected materials.

The technical backbone has no regard for what others think of them.

“Could it be that the rolling mill we are in is actually a secret unit of the state?”

The technical backbone who first discovered the blade structure stood up and said excitedly.

His name is Jiang Jiefang, and he also worked in a military factory before, but because he did not obey the management, he was considered a thorn, and he was the first to cut the staff of the military factory.

“It makes sense to say this, maybe this is a military factory disguised as a private enterprise.”

Another one who spoke was Yang Guoqing.

He was hired back again because he was older.

When the two said this, others also felt that their minds were open.

“That’s right, maybe that’s it, the reason why the director of the factory can come up with this high-end design drawing must be because the unsung heroes who secretly lurk abroad brought it to us.”

In recent years, there have indeed been many people who have lurked abroad and penetrated into the enemy in order to obtain higher technology.

This kind of thing will also be reported in the newspaper from time to time, so the brains of several people are open, which is not outrageous.

Jiang Jiefang nodded repeatedly.

“Maybe our design drawings were sent back to China by those heroes from Eagle Sauce.”

“I’ve only heard of this blade structure, but it’s the first time I’ve seen solid design drawings, and this wide-chord shoulderless hollow sandwich structure has really been developed.”

“That’s right, I have confirmed the process, and our factory can also make it.”

“The person who can invent this structure is really ingenious, and sandwiching a honeycomb sandwich in the middle can supplement the strength and reduce the weight.”

“As long as it is applied to our country’s space shuttle, those gringos will no longer be able to jam our necks!”

The more they talked, the more excited they became, the more excited they became.

“When we designed the engine before, didn’t we just want to understand how to do the blade structure to perfectly improve the efficiency of the engine?”

“Now that we have this blueprint, we must eat it thoroughly!”

Jiang Jiefang waved his arm, extremely excited.

“For so many days, we only understood one blade structure, and there are still many hard bones waiting to see us.”

Yang Guoqing looked at the design drawings, as if looking at his most beloved lover.

“That’s right! Don’t give up, you must eat this design drawing thoroughly, and you must produce it! ”

Everyone couldn’t help but cheer each other up and cheer up.

As one of the top technical backbones in Four Nine Cities at present, if even they can’t eat through this design drawing, then no one can do it anymore.

Therefore, even if they face many difficulties, even if there are still many things they can’t understand on this design drawing, they can only look at it hard.

“Don’t panic, let’s look down one by one. I don’t believe that a small engine can bring us down. ”

“The Long March has come, just such an engine, we must gnaw it!”

Several technical backbones originally had some decadent spirits, because of a breakthrough in the structure of the blade, chicken blood was fought again.

It has been half a month since they got this design drawing, but they haven’t understood it.

There are too many difficulties in the design of aerospace engines, even if they are already a few good hands in the entire Four Nine Cities, they are also broken and sunk.

Just studying a small blade structure took them a full week to complete.

After all, don’t look at the clear dimensions on the design drawings, but what materials and what alloy ratios are actually used to withstand the torque brought by high-speed rotation, these design drawings do not say.

In order to be able to produce a foolproof engine, they must eat every point thoroughly.

The factory that had been specially set up for these technical backbones fell into silence at this moment, only the sound of paper and pen rustling.

“I said, do you think that the director of the factory has a secret identity?”

A younger technical backbone couldn’t help but raise his head and ask.

His question is also something that has been lurking in the hearts of others for a long time.

Su Chen easily took out such an epoch-making scientific and technological product, how not to make several people wonder about his identity.

After all, just from the design part of the blade structure, the legendary technology is in front of them at this moment, and other countries have not even entered mass production.

However, Su Chen had already brought this technical drawing to them.

How this does not explain Su Chen’s identity, how strange it is.

“Go, you boy, do you want to snitch?”

“Director Su’s identity may be fake, he is actually one of our undercover agents, but you better not probe his identity.”

Yang Guoqing coughed, and his originally cloudy gaze appeared extremely sharp at this moment, sweeping over everyone present.

“Don’t think about leaking secrets outside, we have to supervise each other, and if anyone leaks secrets, pick him up!”

After he said this, others agreed.

It doesn’t matter what Su Chen’s true identity is, the important thing is that this drawing must not be seen by anyone other than them…

“I, Jiang Jiefang, came to type this draft first, and I promise that I will never leak the design to anyone, not even my family.”

“Please comrades supervise me, if I leak secrets, you can twist me and arrest me at any time!”

With one person to start, others also began to reassure.

After everyone was guaranteed, the technical backbone with the common secret became more enthusiastic.

They are fully committed to R&D design drawings.

Su Chen thought that his design drawings had not yet come out, and he didn’t know what step he had researched for so long, so he came to the institute to take a look.

This plant, as a temporary research institute established by Su Chen, has been surrounded by people from the security department, just to keep unrelated people from approaching.

Although Su Chen didn’t care about the design drawings in his hand and those epoch-making technologies being seen by others, he didn’t want others to get them casually and take them to make money.

Therefore, Su Chen decisively fenced off this piece and did not allow others to enter.

When he came to the entrance of the institute, Su Chen found that the atmosphere here was strangely warm.

When he came to the door, the workers in other factories would have noticed it immediately, but the technical backbone here did not know it.

One by one, they are like Frankenstein seen in movies, with their hair scattered, and their hands are constantly drawing characters that only they can understand.

One of the most conspicuous is Jiang Jiefang, who is writing mathematical formulas with a pen while chanting some words that ordinary people can’t understand, and Su Chen only listened to one ear and completely fell into a state of blindfolding.

Su Chen didn’t understand at all why these technical backbones behaved like ordinary people before they came, but now they are beaten like chicken blood.

Looking at the busy and chaotic scene of the scene, Su Chen had a little headache, and he casually pulled Yang Guoqing and asked.

“To what extent have you studied the design drawings now?”

Yang Guoqing wanted to get angry, but when he looked up, he found that it was Su Chen who asked, and immediately looked at him with reverence.

“We have now broken through two technical difficulties, and the follow-up progress is also in progress, which is expected to be completed soon.”

“I’m sorry Director, this design drawing is too advanced, and we spent too long on research.”

Su Chen waved his hand, indicating that he didn’t care.

“It takes some effort to parse a design drawing, and it can only trouble you.”

The conversation between Su Chen and Yang Guoqing finally awakened other technical backbones from the research.

Everyone looked at Su Chen with reverence and looked at him with hair.

Su Chen was very puzzled why these preparatory researchers looked at him so strangely.

Fortunately, in addition to their strange eyes, the technical backbones did not do anything to Su Chensu.

Jiang Jiefang, as the temporary research director appointed by Su Chen, also came forward to report the progress.

“It’s such a factory director, we have thoroughly eaten the design of the wide-chord hollow sandwich structure blades without convex shoulders today, and the next thing to eat is…”

Before he finished speaking, he was stopped by Su Chen waving his hand.

“I don’t understand what blades you are talking about, you don’t talk so professionally, just tell me how much your research progress has been, and how long it will take to get the design drawings.”

Su Chen couldn’t understand what the professional terms they were talking about at all, after all, he didn’t understand the engine, although he had been on an airplane, it didn’t mean that he could build an airplane.

Jiang Jiefang was not disappointed, but thought quickly and said in a way that Su Chen could understand.

“Now our research progress should be 70%, and the remaining 30% are very difficult technical difficulties, but our progress is still very fast, and we expect to eat all the design drawings in less than a week.”

Jiang Jiefang’s words are not false, because most of the engine technologies are actually common, but some part of the innovation and small changes in the engine, they need to understand more.

Su Chen was overjoyed when he heard this, and patted him happily on the shoulder and said.

“Yes, Comrade Jiang Jiefang, your research progress is very gratifying, continue to work hard, I will wait for your good news!”

After receiving Su Chen’s praise, Jiang Jiefang’s face turned red, after all, in his eyes, Su Chen was a ruthless person who went undercover in order to make the motherland’s aviation career progress.

“Yes! Director! Mission accomplished! ”
