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

In Xuancheng, Chen Ming is preparing to leave home and go to H City to take the preliminary examination for Mu Shen students. He ranked 97th in the provincial college entrance examination this year and was barely shortlisted for the preliminary examination, but his hope is slim.

To take the preliminary examination, you will mainly get a bonus. If you pass the preliminary examination, you will be favored by Mu Shen and receive generous rewards. You can also directly enter the Xinghai Group to work after graduating from university.

As for being chosen as a student of Mu Shen, it is every student's dream and can only be thought about.

Xinghai Group will cover their round trip and accommodation expenses, as well as food and drink in H City, so they can travel to H City at will.

Their family is two thousand kilometers away from H City. Their family background is average. They have never been out of the province since they were young, not even to the provincial capital.

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

He didn't believe this, but the old man was obsessed with it. No matter what big or small things he did at home, his mother would go to pray to Buddha or Taoist priests. Just like this time when he took the college entrance examination, his mother put a blessing bag in his pocket before the exam.

Of course, his grades were already good, and he did not suddenly perform well.

Chen Ming looked at the triangular lucky bag in his hand and 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, and the truth is the same!

If there is no mother, who will be the bigger one if there is him?" Mother nagged, "Anyway, you just listen to me."

It is the wish of parents to hope that their children will become dragons. If they can become Mu Yang's students, a chicken can also become a phoenix.

When her mother explained it like this, Chen Ming was speechless, and in the end he could only rely on her.

This time, in addition to the important matter of going to H City to participate in Mu Yang's first test on this trip, he also wanted to see the West Lake, Xinghai Group, and experience the smart city. These are the three most worthwhile tourist spots in H City.

point.

Nowadays, smart cities are very popular and have become popular tourist cities around the world. On the streets of cities, you can hear Lao Wai’s exclaiming “OH, MY GOD” everywhere.

For most people, it is a pity that they cannot go inside the Xinghai Group to see it, and can only take a look at the Xinghai Tower from the outside.

The difference is that after their initial trial, they can go to Xinghai Tower to watch it.

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

Along with him, there are thousands of college entrance examination students and freshmen across the country. With a common dream, many media are following this matter to see who in this class can be favored by Mu Yang.

In the past few years, many related households have asked Mu Yang to take care of their students, but Mu Yang refused them one by one. Opening this door will cause trouble in the future.

Recently, Mu Yang has focused his scientific research on aerospace aircraft. 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 complex, and the technology is difficult. It is a huge system project.

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

The core power has been solved, as well as the basics of heat-proof materials, but new problems arise after assembly.

Taking off only requires sufficient speed, but landing is relatively difficult.

Xinghai Group's Xinghuo 1 rocket engine fine-tuning control system is very powerful. Even with only one rocket engine, it can still achieve liftoff.

However, taxiing to land is much more difficult.

Just like a manned rocket, the most difficult part is the return stage. Taking a certain manned spacecraft that successfully returned to Earth as an example, it took more than fifty minutes from the first adjustment after leaving the space station to landing.

The first task during the entire return phase is to reduce the speed of about 80,000 kilometers per hour to zero.

Landing is very difficult without a parachute.

For example, civil aviation aircraft, which land at a speed of 200-250 kilometers per hour, mainly use spoilers, engine thrust reversers and brakes to stop the flight suddenly.

When an airplane lands, it consumes about 70% of its energy, brakes account for about 70%, speed brakes account for 20%, and reverse thrust accounts for about 10%. Moreover, the latter two only work during high-speed taxiing, and are 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 elevator cannot withstand the impact. If it fails, the aircraft will directly hit the ground, making close contact with the hardened ground, and the fire will

Radiating.

Even more unluckily, it collided directly with the ground. The plane was shattered into pieces and there were heavy casualties.

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 displacement nozzle afterburning turbofan engine that it can jet downward at more than 90 degrees and quickly control the horizontal direction.

forward and vertical downward speed, even very slowly, to ensure safe landing.

The displacement nozzle is particularly important.

Other countries have ternary displacement nozzle afterburning turbofan engines and rocket engines. Can they also create 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 aspect, there are many problems, such as heat-resistant coating materials and cooling methods.

This alone has blocked the development of aerospace aircraft for many countries, such as some countries with poor basic industries, which is a bit difficult for them.

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

Therefore, Xinghai Group is engaged in materials and basic industries, and this path is going very well.

Second, there is the issue of thrust ratio.

It's not that countries don't want to build an integrated sky plane, but it just doesn't have a powerful engine.

Mainly due to thrust restrictions, it’s not that we don’t want to build an integrated aerospace plane, we don’t have the conditions.

As long as the thrust is strong, bricks can fly.

Well, if you exaggerate a little more, the building can fly.

This is why countries around the world became very unsettled and frightened after learning that the thrust ratio of Xinghai Group's engines was abnormal.

When the thrust ratio becomes abnormal, there are more things that can be played with.

Netizens from Bangzi Country next door said that Xinghai Group has such good engines, why not build a larger aircraft that is better than the others?

These words are a bit sour, like "You have hundreds of millions of assets, why don't you buy a luxury car or a sports car, that would be so cool."

It’s not that I don’t buy it, but that when I reach this level, my mentality and experience are different, and it’s even more exciting when I feel better.

Why build a big plane? It’s too low. What Mu Yang wants to build is an aerospace plane, or even a spaceship that can actually travel between stars.

The Feilong ground-effect aircraft, which is just an excessive product, can be regarded as a treasure by various countries and cannot be bought no matter how much money is spent.

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

This is Mu Yang's exact words to Zhou Chen. The company has spent money to improve the working environment of workers. Even the workshop has a cooling and insulation system. Warmth in winter and coolness in summer is no longer a problem.

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

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

Netizen Ah San complained, "It is not a good thing for Xinghai Group to have such an advanced factory. When workers get used to such robots, they become very dependent on them and no longer want to do hard work. It is not a good thing for the company."

This sentence is correct, but more sour. It is really difficult to admit that others are excellent.

Mu Yang went to see the development of aerospace aircraft when he had time.

The next few days will be busy recruiting students.

On July 25, the seven new students were finally decided, five boys and two girls, three freshmen, and four college entrance examination candidates.

The three freshmen were led by second-year students Xie Weizheng, Zhong Huayun and He Wang, and the four preparatory freshmen were led by 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 graduated and don't need his guidance very much. He will occasionally give them tutoring sessions.

Therefore, the number of students that he really needs to take care of right now is 13, which is just the limit. If there are any more, he won't be able to take care of him. After all, he is not a full-time teacher.

On August 1st, Mu Yang met with the parents of the new class of students. The meeting did not last long, it was just a chance meeting and a general introduction.
Chapter completed!
