"Muyang was investigated by the police station?!"

Netizens were really shocked when they saw this news. Several pictures showed Mu Yang walking into the police station. This incident cannot be ignored.

But why he entered the police station, netizens are very curious.

Generally, going to the police station is not a good thing.

The report did not go into details, but was full of various speculations, deliberately leading netizens to make wild guesses and stir up the topic.

This report was taken down a few hours after it was published, but it has been uploaded on the Internet and can be said to be known to the entire Internet.

Good things don't go out, but bad things spread thousands of miles.

After Mu Yang learned about this from the public relations department, he asked the public relations department to deal with the reports that deliberately slandered him. He himself did not explain anything publicly.

Captain Liao of the Xihu District Public Security Bureau also called and asked Mu Yang if he could help him explain the reason publicly. Mu Yang replied that he didn't need to do it for the time being. He didn't want to expose the students' development of model aircraft now, otherwise it might be blamed on him.

.

The next day, another report came out, revealing two photos. One of the photos showed a model airplane on a pickup truck.

According to the report, it is speculated that Muyang may be developing an aircraft model, and starting from the aircraft model, he will start developing aircraft or aircraft core components.

"I haven't heard of Xinghai Group developing aircraft, but it is possible to develop aero engines."

"It is not easy to develop an aircraft engine. Although Xinghai Group is very powerful, it seems that it has encountered various technical problems so far, so we have to start with an aircraft model and practice with it first."

"That aircraft model looks very much like the C919. Is it possible? Mu Yang wants to help Somfy develop the engine. Currently, many of the C919's casings and main structures are manufactured by Xinghai Group." Sharp-eyed netizens still saw that the aircraft model was based on

Made by C919.

"It is indeed a C919 model aircraft. It seems that it is really possible for Muyang to develop civil aviation engines. But, why did it end up at the police station?"

A few days after the report surfaced, many netizens believed that Xinghai Group might really be developing civil aviation engines but had encountered difficulties.

The photos of Mu Yang observing the model aircraft C919 were placed on the table by an investigation department in Chou Country.

"What do you think of this?"

"As most people think, it is really possible that Xinghai Group is developing civil aviation engines. However, it seems that Mu Yang has encountered a problem at present and has to use model aircraft to practice."

"Then maybe they have developed model aircraft, haha."

The department boss knocked on the table: "I hope everyone will pay attention to this matter. Xinghai Group is not an ordinary scientific research company. They have disrupted the market in top fields such as chips and CNC machine tools."

"Boss, even if what you say is true, how can it be so easy to develop an aerospace engine with good fuel economy? Hua Guo has been working on it for so many years with no results. The engines for military use are all manufactured at a high cost. Maybe Xinghai Group is not ordinary.

, but if you want to develop an aero engine, it will be difficult to see results until five or six years."

After hearing what this colleague said, the department boss also thought so: "I hope it is as you said. Somfy's C919 has been test-flying many times in recent times, and the progress is very smooth. I am applying for an airworthiness certificate."

"It's useless even if we get a large number of orders. They still use the same engine. If we can get something stuck on the engine, their project will be ruined."

"I'm also surprised. Don't the Hua people see this hidden danger?"

"It was just a fluke. Of course, they successfully developed the C919 and accumulated a lot of experience in manufacturing large civil aviation aircraft. For them, it is already a great success."

"Well, that makes sense!"

The staff in this department are very good at imagining, but they do have real skills. Of course, sometimes there are all kinds of ridiculous things in imagining. It is just a small thing in the first place. Unless it becomes known to the whole world, maybe a person from Hua Country

If the small balloon flies over their country, they may start a war.

Mu Yang, who is far away in Hua Country, does not know these things. He is enjoying himself these days.

After getting the model airplane from his student, he had a lot of fun with it at home with his two children.

The city is not suitable for flying model airplanes, so he took a yacht to play at the rocket launch base, which has a wide enough take-off and landing runway.

Mu Yang and his family spent two days playing at the rocket base. After returning to H City, they went to work on the development of Junyong's afterburning turbofan engine.

After civil aviation engines undergo ground testing, they will also undergo flight tests in the sky.

However, it is not suitable to expose it at the moment. The ground test has not been completed, especially the life test. The test will last for 3,000 hours. The money burned by burning oil will cost more than 10 million yuan.

When all ground tests are completed and optimized, it is estimated that it will take until July or August.

The focus of most scientific researchers on the civil aviation engine project has shifted to military engines. Military engines mainly have an afterburner, called an "afterburning turbofan engine", as well as other devices that require higher temperatures, higher pressures, and more.

High speed and high load make various requirements more stringent.

The afterburning turbofan engine designed by Muyang is somewhat different from ordinary military engines. For example, the combustion chamber is made of an integral design based on metal 3D additive technology. The disadvantage of this integral design is that it is inconvenient to maintain. If it breaks, it must be replaced.

Overall, it's quite troublesome.

For example, designing a binary vector nozzle, fifth-generation dual-redundancy FADEC, high- and low-pressure turbines turning to high-frequency opposites, high-turbulence strong swirl main combustion chamber head, etc.

In order to meet the vertical take-off and landing design and air hover requirements of some aircraft models, such as the F35B fighter jet, Muyang also designed a vertical take-off and landing power solution of lift fan + downward deflection of the engine nozzle + attitude-adjusting nozzle, which is regarded as XH-AN05

The upgraded version of -01J is called XH-AN05-02J. The engine structure is more complex. This will have to wait until XH-AN05-01J is developed.

In the development of the afterburning turbofan engine, attention was paid to the appropriate balance between performance and reliability, durability and maintainability.

A military engine can serve for more than ten or twenty years, during which it must undergo many maintenance operations. Therefore, it is necessary to ensure its interchangeability, that is, its versatility. If a part breaks, it can be replaced with a standard part instead of redesigning it.

It wastes time and costs a lot.

In the machinery industry, the simplest truth is that the more complex and precise the equipment, the more likely it is that problems will occur.

The main design performance parameters of XH-AN05-01J are: the required maximum afterburner thrust is more than 19 tons, the intermediate thrust is more than 13.5 tons, the total pressure ratio is 35, the bypass ratio is 0.3, the temperature in front of the turbine is 1520 degrees Celsius - 1720 degrees Celsius, and the maximum diameter is 1.13

meters, length 4.652 meters, weight 1400 kg.

The fan has a 3-stage axial flow type and the compressor has a 6-stage axial flow type. Both are integral blisk structures. The overall structure is quite different from that of a top-end afterburning turbofan engine.

The thrust-to-weight ratio of XH-AN05-01, the test prototype reaches a thrust-to-weight ratio of 8.6. After optimization, the mass-produced model will be lighter in weight and the thrust-to-weight ratio will be increased.

For the afterburning turbofan engine designed on the basis of the XH-AN05-01 engine, after adding a processed combustion chamber, the conservative thrust-to-weight ratio may be above 13.

But how much the pushing force can be achieved will only be known after testing after the prototype is produced.

As long as the thrust-to-weight ratio is stable above 12, and the fuel consumption requirements are more economical, less noisy, and more stable, if it can be manufactured, it can be said to be the world's best-performing general-purpose engine.

Internationally, the current No. 1 military turbofan engine is the F119-PW-100 developed by GE for the F22. It first flew in 1997 and entered service in 2002. The maximum afterburning thrust of this engine reaches

156 kN, or 15.9 tons, with a thrust-to-weight ratio of 10-11.5. The order price of a single engine is about US$40 million.

The F119-PW-100 is the first aerospace power system in human history with a thrust-to-weight ratio exceeding 10.

The second-ranked military turbofan engine is the F135 engine developed by PW for the F35 fighter jet. It is actually a derivative of the F119 engine. It was installed and successfully tested for the first time in 2006. The maximum afterburner thrust reaches 19 tons.

The thrust is 13 tons during afterburner, and the thrust-to-weight ratio of the mass-produced model is 11.7.

For example, the F35 fighter jet has an empty weight of 13.3 tons and a full load of 31 tons. It is not equipped with two engines, but only one.

Of course, the F35 series is only equipped with one engine. The root of the development of the F35 is low cost. Excluding R&D costs, the manufacturing cost is only about one-third of that of the dual-engine F22.

Except for the F119 and F135 engines, there are not many afterburning turbofan engines with a thrust-to-weight ratio exceeding ten, and there is also the EJ200 of Eagle Country.

It can be said that the F-22, F-35, Su-57, J-20, and FC-31 can be named fifth-generation fighters. The high maneuverability of the aircraft is one of the important requirements, that is, it needs to have a high thrust-to-weight ratio.

engine.

XH-AN05-01J is the fifth-generation afterburning turbofan engine developed by Muyang. It also has the technology of the sixth-generation AN06. However, given the current situation of Xinghai Group, it is still difficult to produce, so it needs to be done step by step and laid out first.

The foundation of the fifth generation engine first.

The total research and development expenses of the F35 series have reached more than 40 billion US dollars. Many countries provide research and development expenses, of which engine research and development expenses account for the majority, which is also the majority of manufacturing costs.

If Xinghai Group successfully develops XH-AN05-01J, it will save tens of billions of yuan in R&D costs compared to its peers. It will have advanced metal 3D additive technology and lower manufacturing costs.

The cost of fifth-generation fighter jets is extremely high. Even Hua’s most advanced future fighter jet, the J-20, would cost 800 million yuan to produce domestically.

If XH-AN05-01J is successful, Huaguo can also develop more advanced fighter jets at lower costs.

Mu Yang is also a fan of military affairs. He does not want to make money, but he also wants to develop an advanced stealth fighter for the country. But as long as the engine is developed, half of the success will be achieved.

The development of the XH-AN05-01J engine has begun. If everything goes well, a prototype will be available in early September. Mu Yang is looking forward to it.

After being busy with the development of afterburning turbofan engines for several days, Mu Yang stayed at home with his children and read magazines.

Since becoming a father, his life has changed drastically. He used to watch football games at home during entertainment and leisure time. Now he watches Peppa Pig, Dora, and Ultraman with his children every day.

In the past, Mu Yang still liked watching Ultraman, but at his age, it felt wrong no matter how he watched it.

This is a little better, but looking at Peppa Pig, it is really uncomfortable, especially when the child makes some demands that are difficult for him to accept.

Xiao Xi grabbed Mu Yang's clothes and had learned how to act coquettishly: "Dad, Peppa Pig is so cute. Can we also raise two pigs? One for my brother and one for me."

"no!"

Mu Yang refused directly. He knew that there were several kinds of pet pigs, and many people in the country kept them.

However, he didn't want his children to raise small pet pigs and eventually turn into raising large pet pigs. Mu Yang couldn't appreciate this weird hobby.

He has now thought about what it would be like to see a few pigs squealing in the hall at home, and the child is not allowed to eat the delicious twice-cooked pork.

"Why?"

"Dad, I apologize to you first. I shouldn't be harsh on you."

Mu Yang knew that it was wrong to reject the child directly without any reason.

After thinking about it for a while, I called my wife and asked her to explain it to the child.

Sometimes, children like to watch Crayon Shin-chan. To be honest, Mu Yang also likes to watch this cartoon, but he does not dare to let his children watch it for fear that the children will learn badly.

Well, at their age, it is indeed not something they can see.

At nearly two years old, his mind is actually about the same as that of a four or five-year-old child. He is so smart.

My wife has taught the children how to read and sing children's songs.

After the child turns three, Mu Yang and his wife plan to send the child to kindergarten, so that the child can integrate into the lives of his peers.

The company has a kindergarten, and Mu Yang and his wife are afraid that their children will become the king of children.

One night, Mu Yang turned on Y TV and watched the program "Dialogue".

He did not participate in this program. The program team also invited him, but Mu Yang refused due to lack of time. This time, Zhou Chen was invited to participate in this program, and the guests at the same time were Ma Si Ke.

This is the second time that Musk has participated in this program. In 2014, he and Mr. Yang of a certain company were both guests.

At that time, the host said that Musk had taken the "fan economy" to the extreme. While he could have free spokespersons, the spokespersons would also spend money to buy cars, and asked Mr. Yang if he was envious.

As soon as this question was raised, the smile on Mr. Yang's face froze and he asked, "Do you know how many customers I have?"

After that, he began to ridicule Musk, saying that a certain person wanted to sell nearly 100 million devices. One day's sales were about equal to Tesla's annual sales. Five units a minute meant that a certain person wanted to have 100 million customers.

I think that due to Mu Yang's influence in this life, the reputation of the computer brand has been damaged, and sales have dropped a bit, estimated to be about 15%. If Mu Yang is willing to stab him a few more times, I think, the damage will probably be more serious.

In 2014, Tesla's market value was indeed not as high as that of Xinghai Group. Even if it developed Model S and used Xinghai Group's ternary lithium battery, sales were good. However, due to the influence of Xinghai Group's Hummer EV, sales were stronger than in previous generations.

But the price is not high, so the profit is not high either.

Musk is participating in this show again because he really wants to open up the Huaguo market for Tesla and is preparing to build a factory in Huaguo.

At present, the fastest growing new energy vehicles in the world belong to Hua, with a penetration rate of 21%.

Mu Yang also had nothing to do and wanted to hear what Zhou Chen and Mask would say this week.

Host Chen Wei said: "Today we have invited two important guests, Mr. Musk, the CEO of Tesla and Space Exploration Technology Company, and Mr. Zhou Chen, the president of Xinghai Group, which is very rare.

Tesla makes new energy vehicles, and Xinghai Group also makes rocket launches. Will there be any conflict between the two businesses? Mr. Musk, what do you think of this issue?"

Malak thought for a moment and adjusted his suit. He felt a little restrained and unnatural, and said: "Xinghai Group is a technology company that I admire very much. It focuses on scientific research and has many world-first technologies, which are in line with what I know.

The Huaguo enterprises are very different.

Although Xinghai Group also produces new energy vehicles, the Hummer EV is an SUV and our Tesla is a sedan. There is no conflict between the two businesses. Moreover, Mr. Mu Yang also holds 18% of the shares of Tesla Company. Our Tesla

We have a cooperative relationship using ternary lithium batteries from Xinghai New Energy.

Even if there is competition in the future, I think it is a good thing for the two technology companies to go hand in hand and jointly contribute to the development of human technology.

In the field of rocket launches, I think the same is true."

The host nodded, Zhou Chen kept smiling.

"Mr. Musk just said that Xinghai Group is very different from most Huaguo companies. In what respect? For example, what companies are there?" the host asked. In fact, he had already guessed some, but as the host,

To ignite topics and increase ratings.

"I remember that I participated in this program last time. Some Chinese companies, especially technology companies, paid more attention to marketing than technology itself. This surprised me." Musk said bluntly that he has this temperament.

It would be nice not to mention names.

"Oh, are you referring to a certain company?" The host did not want to let go of this topic.

Mask spread his hands, smiled, and did not answer.

The host asked: "Mr. Zhou, what do you think?"

Zhou Chen said without any sense of superiority: "Thank you Musk for your compliments. Xinghai Group is indeed a great company with many advanced technologies. This is all due to our strong team and our shrewd leader Mr. Mu Yang."

.

Tesla and SpaceX are both great companies, and we greatly admire Musk’s spirit in scientific research.

I do agree with what Musk said. As a technology company, we should focus on scientific research instead of marketing. The core is upside down.

However, I also hope that the Chinese people will clearly realize that Xinghai Group is only temporarily ranked first in the world in some technologies. In fact, there are many areas that need optimization and improvement, and there are many shortcomings.

We should realize the gap between us and developed countries and that we are still lagging behind in many technologies.

Our chairman talked to me about this topic. He said that no company has ever been number one in the world. He knows better than any of us. I admire the chairman's pragmatism, humility and low-key spirit very much.

Therefore, I hope that Chinese people should not have too much sense of superiority, especially scientific researchers. If this mentality exists, others will catch up sooner or later.

Please also ask the media not to exaggerate Xinghai Group too much. Xinghai Group has nothing to be proud of."

Mu Yang, who was in front of the TV, nodded after listening to Zhou Chen's words. Zhou Chen did understand Mu Yang's thoughts, and Xinghai Group did not need to flatter him.

Hearing this, the host said with admiration: "Hearing Mr. Zhou's words, my respect for Xinghai Group and Mr. Mu Yang rose again.

Even if you stand at the top of the world, you must remain humble, pragmatic, eager to learn, and constantly look for your own shortcomings. This is too scary for competitors."

"Yes, I agree too. This is why I admire Mr. Mu Yang very much." Mask also said.

When Zhou Chen saw the host and Musk praising him, he still kept his previous expression.

The tens of millions of viewers in front of the TV learned more about the Xinghai Group. From Zhou Chen and his words, they also learned more about the leader of the Xinghai Group, Mu Yang.

If you are so good and work so hard, how can your opponent survive?

Mu Yang was in front of the TV. After watching it for a while, he turned off the TV. He just regarded the program as entertainment.
Chapter completed!
