Rebirth 2008: I Can Make Money Reading - Vol 2 Chapter 473

【Rebirth 2008: I can make money by reading】【】

Mu Yang has many ideas, such as holographic automatic projection, flying car, vertical take-off and landing fighter jet, super high-speed high-speed rail, seawater desalination, biomedicine, semi-artificial intelligence, superconducting materials, graphene, quantum computer, ecological spacecraft, genome and biotechnology , Controllable nuclear fusion_…

He casually lists hundreds of technologies he wants to work on.

However, some are temporarily unavailable, and some technologies belong to special shelves with many prerequisites and cannot be purchased even with achievement points.

In addition, Xinghai Group does not have so many talents and venues, and Mu Yang’s personal energy is limited, so it is impossible to engage in so many at once.

In the past year, Xinghai Group has developed EBL lithography machine, chip design software EDA, chip design and five-axis linkage CNC machining center. After calculation, there are four major projects. Each project can provide Xinghai Group every year. bring great benefits.

There are also other new projects, hundreds of new technologies, large and small, and these achievements are very numerous.

For an ordinary large enterprise, it is a great achievement to be able to complete one of the large projects, and it can prop up an enterprise to prosper for decades.

City H, outside Jiangsu and Zhejiang University, a mid-range restaurant, room 2.

In the box, four men and one woman were discussing something very important to them.

This girl has a witty look on her pretty face, and a leisurely smile that is sometimes a little sly, making people warm and elusive. Her thin body is filled with a faint cold aura, low-key and aloof.

The other four boys are centered on this girl, as if surrounded by a noble princess. If the students of Jiangsu and Zhejiang University see this girl, they will know who she is.

Leng Han!

The No. 2 hot-discussed person of Jiangsu and Zhejiang University. Why not number one?

Number one is Mu Xiaoling, a senior, the honorary president of the Volunteer Association, and the actual controller of the Muyang Personal Charity Foundation. He has no less than one billion funds in his hands. Many poor students of Jiangsu and Zhejiang University have received the favor of this foundation.

In the eyes of most students, Leng Han is a lonely sophomore. She seldom hangs out with her classmates, and she doesn’t join any associations or student unions. Some student unions invite her to join, but she refuses.

She spends all day in the library, or in various laboratories, and even walks with wind. When passing students see her, even if they know her, they can’t say hello to her. The boy who has a crush on her can only watch from afar.

Indeed, ordinary boys would not dare to strike up a conversation with her, knowing that there would be no chance.

Since Leng Han was accepted as the first batch of students by Mu Yang, she has personally received 10 million in cash, a house, a car and a driver, and 100 million in scientific research funds during the direct Ph. Multiple research funds.

To be a student of Muyang is the dream of students across the country.

Therefore, Leng Han is called “the luckiest girl” by the students of Jiangsu and Zhejiang University. Of course, everyone has to admire her. She transferred from BJ University to Jiangsu and Zhejiang University. Since being accepted as a student by Mu Yang, she has worked harder. The grade point ranking is the first place in the mathematics department.

Her personal dress is very simple. Sometimes, it may be too late to change, and she comes to class wearing Xinghai Group work clothes, without any accessories, and with light makeup.

But no one would laugh at her for wearing Xinghai Group work clothes in class. Instead, they would envy her. The quality of Xinghai Group’s work clothes is not bad, and it is considered an honor to be able to wear Xinghai Group’s clothes.

Most of the students want to work in Xinghai Group after graduation.

Moreover, I heard that she has already finished the sophomore course by herself, and now she has started to learn professional course knowledge. You can see it from the books she holds all day, partial differential equations, real variable functions, topology, functional analysis, fuzzy math

This is a girl who intends to mix with mathematics for a lifetime.

The most valuable items on her body may be the laptop and mobile phone presented by her teacher, both of which are laser marked by Xinghai Group. I have never seen her buy any brand-name bags.

At this time, in the private room, five people were discussing matters while eating hot pot.

They only do team building once a month, and they usually don’t have the leisure to eat hot pot. Their teachers also advise them

, Get together when you have time, strengthen the relationship, don’t be a tool person for scientific research, but also know how to live.

Leng Han shivered and took a mouthful of hot beef brisket, and said: “The teacher takes care of us, eating, drinking, living, studying and personal development, just like parents. New Year’s Day is the teacher’s 25th birthday. I plan to give you some gifts for the teacher. Do you have any good suggestions? ?

“Senior sister, this is a difficult problem. The teacher has everything. If you ask me this question, I might as well go to a difficult Olympiad. I have been thinking about this question recently, too entangled.”

“Senior brother Jin is right, but it’s the teacher’s birthday, we really want to honor the teacher.” Xie Weizheng, a freshman, looked at the senior brother and senior sister, and said.

There are also two first-year students, Zhong Huayun, the No. 1 student in the college entrance examination from Heilongjiang Province, and He Wang, a recommended student from Qinghua University in Shandong Province.

The five of them, as long as it involves the teacher, they will discuss it together, and they will get together every once in a while. The three freshmen came to Jiangsu and Zhejiang University for three months, but they are already very familiar with the two seniors.

“That’s why I asked you to discuss it together. If it’s so easy, why should I ask you?” Leng Han patted the table down, showing the aura of a senior sister, “We don’t know calligraphy and painting, and the teacher’s house must be well-known, we will send it over. , sorry to let the teacher hang up.”

Xie Weizheng was silent for a while, and said: “The teacher doesn’t like us tossing around and wasting time, senior sister, if we mess around, we will be criticized if we don’t make it right, and it will make the teacher unhappy. We have to send things to his heart.

Xie Weizheng had been in contact with the teacher for three months, and from the words of the senior brothers and sisters, he probably got a sense of the teacher’s character.

“Well, gift giving really depends on the personality of the recipient. What do you think the teacher is most concerned about recently?” “Recently, the teacher has come to the aero engine laboratory a lot more times. I guess the teacher has focused on it.”

“The teacher has two children, why do we have to give the teacher a gift, as long as it makes the teacher happy, isn’t it enough?”

“That’s fine, the question is what to give?”

“Hey, well, the teacher has always been concerned about aero-engines. We are also learning about aerospace knowledge. Recently, we have been involved in aero-engine projects. Now, we can use our knowledge to create a C919 model aircraft that can be remotely controlled. of.”

Zhong Huayun agreed: “Sister, this is a good idea, but I can’t make it too lousy. I used to play model airplanes. It is easy to make a model airplane that can take off normally, but it is much more difficult to land stably. Otherwise, it will hit the ground directly. Fall apart, let the teacher lose face.”

“Air model is fine, I like it best.” He Wang said with a smile.

Leng Han gave He Wang a blank look: “It’s useless if you like it, the teacher has to like it, if the teacher doesn’t like it, at least the teacher’s child has to like it, if the teacher’s wife is happy, the teacher will naturally be happy.”

“Senior Sister, this move is really brilliant.”

“Go away, don’t flatter, talk about serious business, we are short on time.” Leng Han waved his hand and said with a tight face.

About half an hour later, the discussion was almost done, and finally it was decided to give the teacher a model airplane. The time is uncertain, but it is best to send it out before the teacher’s birthday.

As a senior sister, Leng Han is cold on the outside and hot on the inside, and has the strongest organizational skills. She is also a senior sister, and said, “Let me arrange the tasks now.

Junior Brother Jin, you are good at mechanical design. You use AD to draw the fuselage of C919. The material is aluminum alloy and titanium alloy. The cost is based on our scientific research funds;

Wei Zheng, Hua Yun, Xiao Wang, the three of you are responsible for the remote control and ignition system, take-off and landing system, battery and motor issues. If you don’t understand, ask relevant experts. You must know how to use resources.

I’m in charge of solving engine problems. If you have problems that you can’t solve, I’ll coordinate.

I plan to use a turbofan engine for the engine. I am not very proficient in this aspect. I am really uncertain, so I can only ask those experts and teachers for advice.

The scale becomes smaller, and many things become complicated, which may not necessarily be successful.

This aircraft model is our first project, laying the foundation for the development of real aircraft.

the first model aircraft,

Even if it cannot take off, the lithium battery and motor must be replaced to ensure normal sliding, at least for teachers and children to play with.

When taxiing on the ground, the turbofan engine cannot be activated, and the safety of children must be considered. ”

The structure of the aircraft model they want to make must be much more complicated than that of ordinary aircraft models, but it must be much simpler than the real aircraft.

Lenghan’s reduced version of the turbofan engine cannot be realized without borrowing Xinghai Group’s metal 3D additive equipment for processing, and many parts cannot be scaled down indefinitely.

There are folks who DIY a reduced version of the turbofan engine. Lenghan needs to be more professional, and the thrust-to-weight ratio is higher, so naturally the requirements are higher.

Leng Han has been exposed to a lot of mechanical knowledge in the past year, and she has actually learned the professional knowledge of the senior year. This is because the teacher often guides them to make some progress. Otherwise, they will not be able to digest a lot of knowledge in a short time.

She is not high-sighted, in fact, in the past few months, they have been learning from the company’s aero-engine project team. It is difficult to do it. The simplest version can still be made by using the company’s resources. If you really don’t understand, you can ask Experts, experts do not understand, you can ask the teacher again.

The manufactured turbofan engine may have a lifespan of only a few hundred hours, or even dozens of hours. It is impossible to imagine a lifespan of tens of thousands of hours like a real machine.

A turbofan engine is used, and the main body is manufactured with metal 3D additive equipment. Individual parts need precision machining, and the manufacturing cost alone is more than 100,000.

General aircraft model engines use piston engines, solid rocket motors, carbon dioxide engines and pulse jet engines.

At present, relatively expensive model airplanes may cost hundreds of thousands of yuan, or as many as millions, but Leng Han’s requirements cannot be so low. They use the high-end equipment of Xinghai Group to manufacture them, and they have the best resources and no shortage of funds. It would be embarrassing for the teacher to produce a traditional model airplane.

If you want to do it, you have to be the world’s best model airplane, which can have the basic functions of a real airplane. “Sister, what’s the budget? What’s the ratio?” Jin Wei asked a key question.

Although they can borrow the resources of Xinghai Group, they still have to pay the factory. The teacher has already told the financial department that they can go directly to the financial department for reimbursement. If they have no money, they can also go to the financial department to advance the activity expenses. Final reimbursement.

The scientific research fee given to them by the teacher is 100 million yuan, which they can control freely, but it must be used for scientific research.

The teacher gave them a personal reward of 10 million yuan, which is a large sum of money. The five of them never thought about using research funds indiscriminately. Maybe the teacher didn’t care about it, but they couldn’t bear it.

Leng Han thought for a while, and quickly came to a conclusion, saying: “Each person has a budget of one million yuan, and if it is not enough, it is two million. The total budget should not exceed ten million. The length of C919 is 38.9 meters. According to Zhong Huayun’s suggestion, we make One to fifteen is enough. Jin Wei, you need to draw a picture as soon as possible to roughly calculate the weight of the model aircraft. I need to calculate the thrust of the engine and the strength of the structure. We make this model aircraft to lay the foundation for the future. You can’t lose the teacher’s face.

At present, the C919 is quite hotly speculated, and there are always some local tyrants. Maybe we can sell a few to recover the cost. ”

“Tsk tsk, it’s exciting to think about making an airplane model that costs millions.”

“Try to make it before New Year’s Day, it’s really not possible, so we can only postpone it, and wait for the teacher’s son for two weeks

You can send it again when you are old. Therefore, our time is very tight. This month, everyone has to work hard. ”

After the five people finished their meal, they continued to discuss design feasibility and reliability issues.

They don’t need to consider money when doing these things. The teacher’s time is precious, so they definitely don’t care about the money. The most important thing is whether they can learn knowledge and whether they can help the teacher in the future. Otherwise, it will be a waste of the teacher’s precious time.

Mu Yang didn’t know that five of his students were working on model airplanes. He planned to train these five students to develop in the direction of aerospace and nuclear technology. Like Jin Wei and Leng Han, after finishing the basic courses of freshmen and sophomores, the professional courses were biased towards aviation. aerospace.

Although Leng Han is in the Department of Mathematics, she is also an applied mathematics in the field of aerospace, and she is also required to know some knowledge of aerospace.

Muyang is currently advancing the development of the XH-AN05-01 turbofan engine.

The XH-AN05-01 turbofan engine currently developed by Xinghai Group has a thrust-to-weight ratio of 8;

The turbofan engine 10B Taihang engine used in domestic fighter jets has a thrust-to-weight ratio of 8.5. Is the 10B Taihang engine more advanced than XH-AN05-01?

This chapter is not finished, click [next page] to continue reading –>>

【Rebirth 2008: I can make money by reading】【】

Not!

The turbofan 10B Taihang engine can only reach a qualified level in terms of commercial use, which is very different from the commercial turbofan engines of developed countries.

As for civil aviation turbofan engines, there is no decent finished product yet.

The turbofan 10B Taihang engine used on fighter jets can have a thrust-to-weight ratio of 8.5 because it has one more afterburner than the civilian turbofan engine!

What does the afterburner do?

Simply put, increasing airflow temperature is used to increase engine thrust in the short term. This increased thrust is very large.

Generally speaking, the thrust can be increased to 50%, or even more!

With the afterburner, the structure of the engine is more complicated. For example, the airflow in the afterburner will also have strong pressure oscillations. This phenomenon is called oscillatory combustion. Oscillating combustion can cause vibration of structural parts, overheating and flameout of the simplified engine, and even damage to the afterburner.

Therefore, the requirements for the king-use engine are higher.

XH-AN05-01 turbofan engine is a civil aviation engine with a large bypass ratio.

In terms of appearance, it is very large and obvious with the appearance of fighter jets. The civil aviation engine is thick and short; while the king’s engine ~www.mtlnovel.com~ is thin and long.

Regardless of whether it is for civil or royal use, the core is the same.

If the XH-AN05-01 technology is used by the Xinghai Group to increase the afterburner and manufacture a king-use turbofan engine, then the thrust may reach a terrifying 12, or even higher.

The F135 engine equipped with the ugly country F35 stealth fighter is the engine with the highest technical level in the world, with a thrust of nearly 20 tons. It belongs to the fifth generation engine.

Of course, it has many fatal flaws. What is its thrust-to-weight ratio? 11.67!

Therefore, Xinghai Group is really engaged in turbofan engines for kings, using XH-AN05-01 technology, and the technical level is higher than that of F135.

Moreover, XH-AN05-01 has another feature, that is, less noise and better stability.

If Mu Yang intends to adopt the sixth-generation technology of AN06, the thrust-to-weight ratio of civil aviation will be 10, and the thrust-to-weight ratio of the king engine after adding the afterburner may reach more than 15.

The noise of the aero-engine is very loud. If it is a civil aircraft, the noise is too loud, and the ears of the passengers are uncomfortable. Especially some civil aircraft shake from time to time. In addition to the influence of the air flow on the aircraft, it has a lot to do with the stability of the engine.

Muyang intends to make XH-AN05-01 for civilian use, and plans to develop XH-AN05-01 for civilian use in the future.

Of course, the name may not be XH-AN05-01, it may be “XH-AN05-01J”, and “J” stands for “Junyong”.

As for the turbojet engine, its high-altitude and high-speed performance is good, but the low-altitude performance is not as good as the turbofan type and the fuel consumption is large, so now the turbojet type has been gradually eliminated on the aircraft.
