Siheyuan: I can simplify skills

Chapter 125 Doubt

"What materials do you use for these parts?" Professor Chen asked.

"Well, for this batch of parts, we use the latest special steel developed by our factory." Xu Yang said.

"No wonder the quality is so good. And it has excellent resistance to thermal deformation. Isn't this special steel also very hard? Can you process it?" Professor Chen asked puzzledly.

You know, Beigang is unwilling to process their special steel parts because of serious tool wear.That is imported equipment. Even if it is replaced by a low-end tool by a profiteer, it will have better performance and stronger processing capabilities than domestic tools.

"In order to process special steel parts, we have developed new tools with higher hardness. Otherwise, we would not be able to process your batch of parts." Xu Yang said.

"However, the special steel material of your batch of parts seems to be stronger than our batch of special steel." Professor Chen said.

"That's right. Isn't this normal? Shouldn't the special steel formula we recently developed be better than the old formula?" Xu Yang said with a smile.

Um?Is this considered normal?

Professor Chen gave Xu Yang a strange look, "When did your steel rolling mill get involved in metal smelting again?"

"When our factory was built with Damao's help, we originally had a metal workshop. But after Damao's experts withdrew, the metal craft workshop has never been used again. The machines are still new and are very well maintained. I happen to understand At one o'clock, the craft workshop was restored to use." Xu Yang said.

"When did you learn metal smelting again? Aren't you a graduate student in the Department of Mechanical Engineering?" Professor Chen asked.

When I was at Qingda University, I went to the library to read books on many subjects, and also studied metal materials.

Professor Chen was a little tired. Well, if you take a look, you will become an expert in metal materials!The special metal formula developed is better than others who specialize in this research!

Forget it, Professor Chen decided not to pursue these details.That's not what he came here for.

"You can help us process another batch of parts using your special metal. Do you have any other types of special metal here?" Professor Chen briefly outlined the needs.

Xu Yang immediately took out several special metal formulas.However, there are only various parameters of these special metals.

"Are these parameters serious?" Professor Chen beamed.

If these metal formulas can really achieve the above performance, then several problems faced by the fighter development team will be easily solved.

"Of course, we have tested it. The actual performance may be a little better than this. These are design parameters, which are slightly conservative." Xu Yang said.

Professor Chen was ecstatic: "Give me these parameters first, and I will go back and study them. There may be a batch of parts that you need to process. Are the quantities of these materials enough?"

"We produce these materials ourselves. If the quantity is not enough, we can produce them at any time. However, the cost of small batch production is relatively high. Our steel rolling mill is small in scale and cannot afford the huge cost investment." Xu Yang said.

"No problem, we will take care of the funds." Professor Chen said.

Professor Chen rushed back to the R&D team in a hurry.

The fighter research and development project team immediately held a meeting to discuss.Replace a large number of parts.

Chief Engineer Gao of the new fighter jet development project nodded to Professor Chen: "Professor Chen, please tell me the situation."

"After this accident, we investigated the cause of the accident and found the faulty component. In addition to processing problems, material problems were also one of the important reasons for the failure. But at the same time, we also discovered a special situation. By Kyoto Steel Rolling A batch of parts processed by the factory performed very well. The wear was very small, the heat resistance was very strong, and the strength was even better than our special steel parts. So I made a special trip to the rolling mill to understand the situation. Only then did I know They have developed new special steel materials. The performance is very good. Not only that, they have developed some special materials. Many of them can be used in our projects. This is the list of special steels I brought from the steel rolling mill. And the special materials Performance parameters." Professor Chen handed the information to Chief Engineer Gao.

When Chief Engineer Gao saw it, he immediately beamed with joy.

"Professor Chen, are the properties of these materials really so good?"

Professor Chen nodded: "The other party said that the actual performance may be higher than the design parameters. They still have reservations about the actual parameters of the special materials."

"Everyone, take a look! Do you have any comments?" Chief Engineer Gao passed on the information on special materials.

A lively discussion immediately erupted in the conference room.

"Impossible! Our materials are all the best materials from the Institute of Materials. How can a precision rolling mill develop better metal materials than those from the Institute of Materials?" someone said excitedly.

"How is it impossible? The special steel material used in the last batch of parts they processed for us is much stronger than the special steel material we obtained from the material!" Professor Chen said.

"If you want me to see, it's best to verify it. Replacing parts and materials is no joke. If there is a problem with the materials, who will be responsible?" Deputy Engineer Luo said with some worry.

Chief Engineer Gao pondered for a moment and nodded: "Lao Luo is right. We still need to consider it carefully. First go to the steel rolling mill to see if the performance of their special steel materials can meet these parameters. If it can, Then we will decisively replace parts and materials.”

Deputy Chief Engineer Luo also agreed: "Without investigation, we have no right to speak. Let's speak with facts."

Therefore, Fighter Engineering sent a special inspection team to the steel rolling mill.

Secretary Yang is used to it now.The levels of visiting teams are getting higher and higher.It shows that the influence of steel rolling mills is growing.

This time, Chief Engineer Gao personally led the team. Chief Engineer Gao also had another identity, that is, the deputy director of the aircraft manufacturing factory.The level is much higher than Secretary Yang.

"Secretary Yang, let's not make such nonsense. The main purpose of our coming here this time is your special steel. Your parameters are very gratifying. We have to see how far the time parameters can reach. Only then can we determine whether we can start from You purchase from here." Chief Engineer Gao acted vigorously and resolutely.

Secretary Yang quickly took the inspection team to Xu Yang.

"It just so happens that these special metal materials are readily available here. Go and test them yourself. Otherwise, you won't believe the parameters we report to you." Xu Yang asked a college student to lead the inspection team over.I was too lazy to go to the reception.He also has a temper. The parameters are given to you, but you don’t believe them.Then I don't want to waste my time... Anyway, it's you who are asking for something from me, not me who is asking for something from you.

Secretary Yang didn't say anything. Xu Yang himself was not wrong in this matter. Even if Xu Yang was wrong, he would still stand by Xu Yang.Now the steel rolling mill really doesn’t have to ask anyone else.I can’t even push off the processing tasks.

Chief Engineer Gao and his party were a little embarrassed, but they could only do as they pleased.

But the test results surprised the inspection team.

Chief Engineer Gao also went out of his way to express his apology to Xu Yang: "Xugong, it's not that we don't believe you, but we really need to be cautious. There was a serious malfunction during the test flight this time, and the aircraft almost crashed. It's better to be a test pilot. We worked hard to save the plane. Next, we have a large number of processing tasks and need your assistance. I hope you don't have any objections to us."

"General Manager Gao is serious. In fact, I am also very interested in fighter jets, and I once went to study at Beihang University. Maybe I will have corresponding cooperation with you in the future." Xu Yang said.

"Really? Then I hope we can cooperate in the future." Chief Engineer Gao didn't take Xu Yang's words to heart.How can a person engaged in precision machining understand airplanes?An airplane is not such a simple thing.Otherwise, their project would not have endured so much hardship.

A few days later, the processing tasks for the fighter project were sent to the steel rolling mill.And the processing priority is ranked first.People jump in line directly.

The processing task may seem arduous, but for a steel rolling mill with nearly ten CNC machining centers, it is really not a difficult task.

Xu Yang doesn't need to take care of these things now. His team of college students will do these things well.

Only when these teams encounter difficulties that cannot be solved, Xu Yang will go out and solve them.

The aviation engine parts Xu Yang needed were also slowly processed.It just so happens that the parts are processed in the order of aviation engine installation. During the processing, Xu Yang can assemble them.When the processing is completed, Xu Yang's assembly can also be completed.

Prior to this, Xu Yang was originally planning to cooperate with Professor Chen's fighter research and development team.But after this incident, he changed his mind.

4.8 Even if his aviation engine is built, the fighter team may not adopt it.Because they will not believe that steel rolling mills can produce more reliable aircraft engines than professional aircraft manufacturers.

Moreover, the concept of the fighter research and development team is relatively backward in the world. They learned Da Mao's technology, and they can only come into contact with Da Mao's relatively backward technology.Da Mao people will never hand over their most advanced technology to China.Because Da Mao Yi has always been on guard against China.It lasted until the disintegration of Da Mao.Even after the disintegration, Da Mao was still very wary of China.

The most advanced fighter jets are sold to the third brother but not to China.This shows that Mao is on guard against China.

In this case, why not design a more advanced fighter yourself?

Xu Yang felt that he could take out the F16.

In the time and space that Xu Yang traveled through, when the J-8 entered service, when it was directly facing the world's advanced aircraft such as the F16 and Mirage 2000, the J-8 was already lagging behind.

Back then, China had the opportunity to purchase F16 and Mirage 2000.However, whether it is a Gallic rooster or an old American, the asking price is very high.In the end, China had no choice but to give up and could only continue on the path of research and development.

Chapter 126 Qin Huairu was eliminated

It is not without reason that China is so eager to develop a new generation of fighter jets.The island on the other side often sends U2 fighter planes to take frequent photos of military facilities under construction and other important strategic bases.

The road is like a naked beauty, allowing others to peep at it.This is intolerable to anyone.

However, at that time, all types of air defense weapons were unable to effectively attack the U2 at an altitude of more than 100 meters.The maximum caliber [-]mm anti-aircraft gun of the air defense force has a maximum range of only more than [-] meters.However, at that time, Air Force fighters were beyond reach.

Therefore, the latest fighter project was launched.However, due to insufficient technical reserves, the development process of fighter jets was full of twists and turns.

This time, although some problems were solved by relying on the CNC machining center of the steel rolling mill and this batch of new materials.But that doesn’t mean the project will be smooth sailing from now on.

But these have nothing to do with Xu Yang.Xu Yang no longer intends to cooperate with the fighter research team. He wants to independently develop a fighter aircraft.

But as a result, Xu Yang's work became more and more difficult.

When Xu Yang told Secretary Yang his thoughts, Secretary Yang jumped up from his stool on the spot.

"what?"

"I mean, how about we build the plane ourselves?" Xu Yang said.

"Are you crazy, or am I crazy? Xiao Xu, are you dreaming? Are we building airplanes in the steel rolling mill?" Secretary Yang looked at Xu Yang. Is this guy sick and his brain burned out?

"Secretary Yang, actually you don't have to be so surprised. Building an airplane is not an unattainable task. The difficulty is not much higher than that of our CNC machining center. Our technical reserves are even worse than the fighter team that came last time." Xu Yang said.

"Are you really sure?" Secretary Yang said.

"I'm absolutely sure." Xu Yang nodded confidently.

"Let me think about it." Secretary Yang did not agree immediately.

"We can do this secretly and keep it secret for the time being. We can just build a big warehouse. We can build it secretly in the warehouse. We will report it when it is completed," Xu Yang said.

"This is not impossible." Secretary Yang was a little tempted.

Now that the steel rolling mill is under the control of Secretary Yang, without the constraints of people like Deputy Director Li, Secretary Yang can roll up his sleeves and go to work.

In fact, this is also very beneficial to Secretary Yang. If the steel rolling mill can build a fighter jet, then the steel rolling mill may be spared from the impact of the next big storm.Secretary Yang can rely on this great contribution and will not be affected.

"Actually, we don't need much investment. We can make everything ourselves. It's actually easier to build a fighter jet than an aero engine. A fighter jet has more than 1 parts. But an aero engine has nearly [-] parts. The biggest difficulty in developing early fighter jets is the aviation engine. We have almost solved the aviation engine problem. In this way, we have solved half of the problem of fighter jets," Xu Yang said.

Secretary Yang was deceived by Xu Yang, and his mind became hot, so he agreed in a daze. After Xu Yang left, Secretary Yang suddenly realized: "What did I agree to Xu Yang? Building airplanes in the steel rolling mill is really feasible. ?"

Because the fighter jet project must be kept strictly confidential, Xu Yang will definitely not be able to recruit additional personnel for this project and can only use existing personnel.

Xu Yang then worked on the drawing design all day and night.Then take the time to assemble the aircraft engine.

CNC machining centers are also constantly being built, but Zhao Xiangdong, Guo Dapizi and a few college students have already mastered the assembly of CNC machining centers.Basically, Xu Yang doesn't need to worry about it.

Xu Yang goes home very late every day.

When I got home that day, it was almost dark, and the incandescent lights at the entrance of the courtyard were already on.

Xu Yang walked to the door of his house and was about to open the door and enter the house when Qin Huairu came over.

"Xu Yang."

"Sister-in-law Jia, is something wrong?" Xu Yang asked.

Qin Huairu nodded: "Can I go sit at your house?"

Xu Yang shook his head: "If you have anything to say, let's talk here. It's not a good idea to go home."

Qin Huairu's expression changed slightly. I was already ashamed, but you refused directly.

"The improvement workshop assessment is over today." Qin Huairu said.

"Really? I didn't pay much attention. I didn't expect that the three-month deadline was coming." Xu Yang really didn't pay attention to the news.

"I was eliminated. I will be assigned to work in the ordinary workshop tomorrow." Qin Huairu glanced at Xu Yang to see how Xu Yang would react.

Xu Yang didn't take it seriously at all: "This is inevitable. Improving the workshop has high requirements for employees. This is to enhance employees' competitive awareness and not to deal with the problem. Since you have been eliminated, go to work in another workshop. . Maybe a job in an ordinary workshop is more suitable for you."
