Chapter 599 We Are Not Short of Money, so We Won't Sell It!

"Son, I'm going to H city for the first test tomorrow. Take this lucky bag with you. I went to the county temple to burn incense and pray to Buddha the day before yesterday. May my son win the lottery."

In Xuancheng, Chen Ming is about to leave home and go to H City to take the Mushen student preliminary examination. He ranked 97th in the provincial college entrance examination this year, and barely qualified for the preliminary examination, but his hope is slim.

To participate in the preliminary examination, the main purpose is to mix a bonus. If you pass the preliminary examination, you will be favored by Mushen, and the reward will be generous. After graduating from university, you can directly enter the Xinghai Group to work.

As for being chosen as Mushen's student, it's every student's dream, so I can only think about it.

The Xinghai Group covers their round-trip and accommodation expenses, as well as food and drink in City H, so they can travel to City H as they please.

Their family is 2,000 kilometers away from H City, and their family background is average. They have never been out of the province since they were young, and they have never even been to the provincial capital.

I heard that Mushen doesn't like students who can't be independent, so he has to go out in person this time. His luggage has been packed, but his mother stuffed a triangular lucky bag wrapped in red paper into his hand, which made him very embarrassed.

He doesn't believe this, but the old man is obsessed with it. No matter what big or small things are done at home, his mother will ask Buddha or priests, just like this time when he took the college entrance examination, his mother put a lucky bag in his pocket before the exam.

Of course, his grades are already good, and it's not that he suddenly performed well.

Looking at the triangular lucky bag in his hand, Chen Ming couldn't laugh or cry: "Mom, Mu Yang is a scientist, he only believes in science, not this."

"He may not believe it, but his mother will, the reason is the same!

If there is no his mother, where is he, who do you think is older. "Mother nags, "Anyway, you just listen to me. "

It is the parents' wish to hope that their children will become dragons. If they can become Muyang's students, chickens can also become phoenixes.

Chen Ming was speechless when his mother explained it like this, and he could only follow her in the end.

This time, he will travel far away to take part in Muyang's first test in City H. He also wants to visit the West Lake, Xinghai Group, and experience the smart city. These are the three most worthwhile tourist spots in City H. point.

Now the smart city is very popular, and it has become a popular city for global tourism. On the streets of the city, you can hear Lao Wai's amazing "OH, MY GOD" everywhere.

For most people, it is a pity that they cannot enter the Xinghai Group to watch it, but can only take a look at the Xinghai Building from the outside.

The difference is that after their initial test, they can go to the Xinghai Building to watch it.

The next morning, Chen Ming left home, took the train to the city, and headed for the future.

Together with him, there are thousands of college entrance examination candidates and freshman students across the country. With a common dream, many media follow this matter to see who can be favored by Mu Yang this year.

In the past few years, many related households have asked Mu Yang to take students with them, but Mu Yang has refused one by one, opening this hole will cause trouble in the future.

Recently, Mu Yang has focused his scientific research on aerospace aircraft, and it has been more than a year since the project was established.

Compared with other projects, this kind of aviation and aerospace technology is highly integrated, the system composition is very complicated, and the technology is difficult, which is a huge system engineering.

A large number of key technologies need to be broken through, such as the determination of design criteria, the development of heat-resistant materials and lightweight materials, and the development of aerodynamic and advanced scramjet engines.

The core power has been solved, and the basics of heat-resistant materials have been solved, but after assembling together, it is a new problem.

Take off as long as you have enough speed, but landing is relatively difficult.

Xinghai Group's Xinghuo-1 rocket engine fine-tuning control system is very powerful, even if only one rocket engine is used, it can still achieve lift-off.

However, taxiing and landing is much more difficult.

This is the same as a manned rocket. The most difficult part is the return phase. Taking a manned spacecraft that successfully returned to Earth as an example, it took more than 50 minutes from the first attitude adjustment after leaving the space station to landing. The first task of the entire return phase is to reduce the speed of about 28,000 kilometers per hour to zero.

It is very difficult to land without a parachute.

Like civil aviation aircraft, the speed of landing is 200-250 km/h, mainly through the spoiler, engine thrust reverser and brake device, to realize the sudden stop of flight.

Aircraft landing consumes energy, brakes account for about 70%, speedbrakes account for 20%, reverse thrust about 10%, and the latter two only work in high-speed taxiing, and basically useless when the speed is lower than 150km/h.

But no matter how good the horizontal deceleration is, the vertical landing speed is difficult to control, and the hydraulic lifter can't resist that kind of impact. If it fails, the plane will directly hit the ground, making close contact with the hardened ground, and the flames radiant.

Even more unlucky, it directly collided with the ground, the plane was shattered, and the casualties were heavy.

There are many such accidents!

If you switch to an aerospace plane, the landing speed from space will be faster, and the requirements will be more stringent. It is precisely because of the three-dimensional vector nozzle afterburning turbofan engine, which can jet downward at more than 90 degrees, and can quickly control the horizontal forward direction. And vertical downward speed, even very slow descent, to ensure safe landing.

Vector nozzles are particularly important.

Other countries have ternary vector nozzle afterburning turbofan engines and rocket engines, can they also manufacture integrated aerospace planes?

It is easy to build and easy to fly, but it is very difficult to ascend to space and land safely. There are two main technical difficulties.

First, from a basic point of view, there are many problems, such as heat-resistant coating materials and cooling methods.

This alone has blocked the way for many countries to develop aerospace aircraft, such as some countries with relatively poor basic industries, which is a bit embarrassing for them.

Even if they are given heat-resistant coating materials and process information, if there is no corresponding construction equipment and skilled workers, construction will still be a problem.

Therefore, Xinghai Group is doing well in materials and basic industries.

Second, the thrust ratio problem.

It's not that countries don't want to build integrated sky planes, but that they don't have powerful engines.

It is mainly limited by the thrust. It's not that I don't want to build an all-in-one aerospace plane. There is no condition.

As long as the thrust is large, bricks can also fly.

Well, to exaggerate a little bit, buildings can also fly.

This is also after the countries knew that the thrust ratio of Xinghai Group's engines was abnormal, they became very uneasy and frightened.

The thrust is higher than abnormal, and there are more things that can be tossed.

The netizen from Bangziguo next door said, Xinghai Group has such a good engine, why not build a larger aircraft that is better than it.

This is a bit sour, like "you have hundreds of millions of assets, why don't you buy a luxury car or a sports car, how cool it is".

It's not that I don't buy it, but that at this level, my mentality and experience are different, and it's even more different when I feel refreshed.

What kind of big plane is there? It's too low. What Mu Yang wants to build is an aerospace plane, or even a spaceship that can really travel between stars.

It's just that the Feilong ground-effect aircraft, which is an excessive product, can also be regarded as a treasure by various countries, and it can't be bought for any amount of money.

"We are not short of money, so we won't sell it! Even if we can sell it, we won't sell it."

This is what Mu Yang said to Zhou Chen. The company spent money to improve the working environment of the workers. Even the workshop has a cooling and heat preservation system. It is no longer a problem to be warm in winter and cool in summer.

Since the promotion of intelligent robots, the labor intensity of workers has been greatly reduced, and workers have to shift from "physical work" to "mental work".

Many workers also joked that they no longer feel like workers.

Asan netizen complained that "Xinghai Group's advanced factory is not a good thing. After workers get used to this kind of robot, they are very dependent and don't want to do hard work anymore. It is not a good thing for the company."

This sentence is also true, it is more mixed with sour taste, it is really difficult to admit that others are excellent.

When Mu Yang is free, he goes to watch the development of aerospace aircraft.

In the next few days, I will be busy recruiting students.

On July 25th, the seven newly recruited students were finally settled, five men and two women, three freshmen, and four college entrance examination students.

The three freshmen were led by the second-term students Xie Weizheng, Zhong Huayun and He Wang, and the four preparatory freshmen were led by the third-year students Chu Yun, Zhan Shengcai and Xiao Dejie.

There are more students, and Mu Yang spends more time teaching students every week. Leng Han and Jin Wei have already graduated, so they don't need his guidance very much, and he will occasionally give them a tutorial.

Therefore, the number of students that really needs to be brought is 13, which is just the limit. If there are more, it will not be enough. After all, he is not a full-time teacher.

On August 1, Mu Yang met with the parents of the new class of students. The meeting didn't take long, just to meet and get to know each other.

There are too many students, so I don't have so much energy to take care of these trivial matters.

How much to write every day, how much to update, don’t ask for the number of words, wait until the status is better
