Chapter 738

Afternoon, five o'clock.

The college entrance examination mathematics is over.

No one expected.

The candidates of this class were made cry again by Gu Lu.

The candidates walked out of the examination room one by one, sobbing.

The reporters interviewed first-hand news.

And put it online.

On the Internet.

Netizens are still a popular scene.

After Mr. Gu joined the college entrance examination math question set group, everyone realized that the college entrance examination would be so interesting.

Especially for those who have already gone to college and entered society.

"Sisters, don't be too sad. As a freshman, I'll tell you as a veteran, don't shed too much tears now. This is not worth it, because you will not understand what real despair is until the day the college entrance examination is achieved in a month!"

"Isn't it just a difficult question? What's the matter? Students, remember one thing, we're waiting for you on the construction site in the wind and rain!"

"I won't work hard in the college entrance examination this year. In September, Lanxiang is a brother. Everyone, our Lanxiang Electric Welding major sincerely invites everyone to join!"

"I'm curious about what the average score for the college entrance examination mathematics this year?"

"I bet it shouldn't be more than forty."

"Uncle Gu: You just take the exam, I will lose if you pass the exam!"

"Hahaha, I like to hear, I like to hear, I like to hear, fortunately my parents gave me a few years earlier, otherwise I might have to endure any inhuman torture during the college entrance examination!"

"I feel happy. The senior senior sister was licking ice cream in the air-conditioned room. She looked at the group of students crying in a crying voice, and said she was very happy."

"Do you guys above, don't be happy too early. Yes, you were born at a very time, missed the era of Mr. Ge, and didn't meet Mr. Gu's era, but your children! Don't forget that Mr. Gu is only in his twenties this year. When your children take the college entrance examination, Mr. Gu may be less than fifty years old and will still be the leader of the college entrance examination math question set! The debt you owe will be paid by your children."

"Damn, why didn't I think of this! No, you should pay attention to some safety issues when handing over public food to your wife in the future, and don't cause life or harm the child!"

"I am still single, and I am fearless!"

"…I want to ask, is it still time to abort now?"

Perhaps what Gu Lu himself did not expect was.

Because of him.

The fertility rate in China has dropped significantly in recent years.

…………

After the college entrance examination is officially over.

The popularity of the college entrance examination, a major event that everyone is concerned about, gradually fades away.

The hot search list was once again occupied by gossip news from some celebrities.

However, a topic called #Uncle Gu, please spare your life# was in the top ten of the hot search list for a week before it fell into full bloom.

now.

Gu Lu is the most famous figure in the mathematics community in China.

Perhaps only Hua Luogeng, Chen Jingrun and others at their peak could steadily suppress Gu Lu in terms of popularity.

But Gu Lu is famous.

It is not because Gu Lu is a once-in-a-century mathematical genius in the Chinese mathematics community, nor because Gu Lu is the first person in the younger generation in the Chinese mathematics community.

It’s because of Gu Lu’s identity as the leader of the college entrance examination mathematics question set group.

He has killed millions of candidates for three consecutive years.

Gu Lu has achieved the achievement of triple      kill.

In China.

No one will forget the name Gu Lu for at least the next twenty years.

And at the same time, on the other side.

Rocket R&D Base located deep in the Dongchang Mountains.

Gu Lu, who cut off any contact with the outside world, certainly did not know about these things happening online.

Gu Lu is currently devoted to the research and development of liquid oxygen kerosene engines.

Liquid oxygen kerosene engine is a big object.

The weight is generally around five to ten tons.

The liquid oxygen kerosene engine designed by Gu Lu has a terrifying weight of eleven tons due to its large structure.

In the research and development workshop of the liquid oxygen kerosene engine, Gu Lu was sitting on a chair and modifying the engine drawings on the table.

The engine designed by Gu Lu has a total of 4 combustion chambers, a turbo pump and 2 precombustion chambers.

Among them, the turbine pump is a single stage, and the entire turbine pump system also includes an oxidant pump and a two-stage fuel pump. The entire system is connected to a low-pressure fuel pump and an oxidant pump, and the propellant is pressurized to prevent the turbo pump from forming holes and thus prevent the occurrence of combustion instability.

This turbo pump has two oxygen-rich pre-combustion chambers that form high-pressure gases after combustion.

At first, Gu Lu originally planned to use only one pre-furnace.

But in this way, 1.5 tons of propellant need to be burned out per second, which is too large.

later.

Gu Lu increased the pre-fuel chamber to two, so that the flow rate could be maintained within a reasonable control range.

During the entire oxidant and kerosene circulation process of the engine designed by Gu Lu, only a small part of the propellant passed through the pre-combustion chamber, accounting for about 6%.

The turbo pump can generate about 257,000 horsepower, equivalent to nearly 10 million Newtons of thrust.

The engine designed by Gu Lu can throttle to 50% of the rated power and is equipped with a universal joint - a steering device, which is performed with 8 hydraulic actuators and can swing along two axes.

Therefore, the engine designed by Gu Lu must consider the reliability of these 8 hydraulic actuators, and must prevent air from entering the arrow body through the rotary joint, so a powerful driver must be used to prevent aerodynamic pressure.

This involves very complex dynamic model problems.

However, Gu Lu has used the model construction to solve all these problems.

And according to the model engine involved in the drawings, there are no major problems when burning and running.

What Gu Lu is currently doing is just assemble the liquid oxygen kerosene engine on the pattern.

This is not a very simple job.

Because every part of the engine is too heavy.

Even with the assistance of Gu Lu's crane and robotic arms, it would be quite exhausting to install.

But fortunately.

This is not a technical job.

Gu Lu has designed all the data parameters of the liquid oxygen kerosene engine on the drawings.

Gu Lu just needs to assemble according to the brainless assembly designed on the drawings.

Even in a sense.

This is even easier than assembling a desktop computer.

"This pressure pump should be installed in the place connecting the pre-combustion chamber pipeline, and this secondary pre-combustion pump is installed in the pipeline connecting the pre-combustion chamber and the combustion chamber..."

Gu Lu was muttering something while continuing to install it regardless of the dirty environment around him.

At this time.

It happened that Director Nie from the workshop passed by.

Gu Lu called out Director Nie.

"Professor Gu, is there anything wrong?" Director Nie stopped.

"Director Nie, can you call Director Bi here?" Gu Lu grinned, revealing a row of neat and white teeth.
