Technical analysis, seeking to revitalize China’s science and technology

Chapter 19 Martial Law Period
dormitory.

As soon as Li Youchen returned to the dormitory, he met Teacher Zhao Hong in the corridor.

inside the house.

"Tell me, what's going on? Yesterday, that Max wanted to invite me for the second time, but I rejected him again, and the next day the whole school was under martial law."

"Outsiders are restricted from entering the campus, and college students and teachers are restricted from going out."

Zhao Hong felt that it must be related to him, so he came over to ask.

"You can't hide it from the teacher. The situation is like this. After the foreigner came to the teacher, and when he was about to leave, I found something wrong. Could the high-paying recruitment be a scam? The most important thing is, could it be related to recruiting talents?"

"I think unscrupulous foreign companies will use loopholes in domestic laws and recruit high-paying jobs as bait to attract students and teachers in universities."

"Simply call the police and ask them to handle the matter."

"In the end, it ended up like this."

In front of Teacher Zhao Hong, Li Youchen couldn't lie and told the truth.

"You kid..."

Zhao Hong looked like he was about to reprimand and said, "What a great job."

Li Youchen was a little surprised that Zhao Bapi was not really angry after hearing this.

"It seems that I did nothing wrong by calling the police?"

Li Youchen scratched his head and looked indifferently.

"Of course not, and he did it very beautifully. How could someone other than those from a foreign company pull such a scam and not be noticed by the Maintenance Police Station."

"After all, further investigation will involve the big issue of missing persons."

"So those people can no longer come from outside the school."

Zhao Hong felt that if such a case occurred, those foreign companies would be destined to be investigated by the Maintenance Police Station. Once the crime of deception was formally established, the sentence would not be far away. After all, these are major cases involving human lives.

"Speaking of which, boy, why did you come back so late in the afternoon?"

Zhao Hong changed the topic and asked.

I thought of looking for him in his personal dormitory before, but found that no one was there at all.

As a result, when I was about to go to dinner, I met him in the corridor.

"It's in the smelting plant, entrusting others to produce relevant titanium alloy steel."

Li Youchen looked around and continued in a low voice:

"Teacher, I am still designing the technical drawings of a small turbofan engine. This is very critical, so I spent some time outside."

Zhao Hong rubbed his chin and crossed his arms:

"So, the technical drawings of the small turbofan engine have been designed?"

Li Youchen took out the technical drawings and showed him:

"Exactly. It was imitated and rewritten based on the original manuscript of the turbofan engine of the fourth-generation fighter aircraft, and the proportion was reduced to create some simple designs."

Zhao Hong found the drawings of a small turbofan engine and looked at them carefully:
"The design principle of such a small turbofan engine is simpler than the structure of a large turbofan engine. If you are not knowledgeable, it will be difficult to understand."

"But speaking of the design of the turbofan engine, do you plan to install two turbofan engines in the design of the model machine? Or one turbofan engine? Can it push the model machine forward?" Zhao Hong was a little confused. There were two words written on the drawing. In a word, make two turbofan engines.

"As for model machines, one or two will do."

"For fourth-generation fighters, the power generated by a turbofan engine is far from enough." "At least two starts. In the future, fighter jets will still be the main air superiority weapon against the enemy. The advantage of fourth-generation fighters is their movement speed, which must be fast. , whether you can accurately hit the enemy's nest, the speed of getting there is very important."

"I have calculated that the kinetic energy generated by the twin turbofan engines can be increased by about 50.00% over the original speed limit."

"That is, the movement speed of Mach [-] is increased by half to Mach [-]."

Li Youchen has calculated in detail that when two turbofan engines are installed together and started at the same time, the original speed limit will be increased by 50.00%, which is a substantial improvement based on the basics.

If oxidant is added, the speed can be increased by 20.00%.

What is needed inside the turbofan engine is air for the violent combustion of kerosene and compressed air. The injection of oxidant will also make the combustion of the violent air more vigorous and generate more kinetic energy.

"Increase by 50.00%. Over at Yingjiang, in the fourth-generation fighter developed, it is indeed mentioned that dual turbofan engines are installed together. Although in terms of load capacity, it will increase a lot of weight, considering that it is a dual turbofan engine The engine has greatly improved the upper limit of movement speed, but it is not more than the 50.00% you mentioned."

Zhao Hong first thought of the fourth-generation fighter aircraft being planned and developed by Yingjiang at this moment, which has dual turbofan engine installation research.

"Yingjiang has already started developing a dual-drive fourth-generation fighter jet."

"It is said that the F-22 Raptor fighter jet, which was reported to have made its first flight last year, uses a dual-drive design. It seems that I have to hurry up and develop it."

Li Youchen clenched his fists, feeling that technically he was still being overpowered.

"Seize the time, although it is very important. The most important thing is that you, boy, are you really going to complete the research and development of the fourth generation fighter within a few years?"

Zhao Hong asked about this.

"If the details are worked out, the development of the fourth-generation fighter jet can be completed in up to half a year."

"At that time, there are plans to free up our hands to develop fifth-generation fighters after the fourth-generation fighters. However, under the current conditions, I cannot yet realize the research and development of fifth-generation fighters. After all, developing fourth-generation fighters alone will make me very exhausted."

Li Youchen needs half a year to complete the research and development of the fourth-generation fighter. After all, the technical drawings are complete, but the most difficult problem is the material issue.

In particular, titanium alloy steel must maintain continuous supply under quality assurance and demand. Otherwise, material issues will become the biggest safety issue in the manufacturing process of fighter aircraft.

"How did you get your confidence in half a year?"

"Even if the project team specializes, it will take at least three years."

"Are you that confident when you come here?"

Zhao Hong pointed and questioned.

Li Youchen put his hands on his hips and said with a smile: "After all, I have the core construction technology of fourth-generation fighters."

"Half a year is pretty fast."

Zhao Hong raised his eyebrows and almost forgot that there were technical drawings of the core structure of fourth-generation fighter jets. It was really possible to complete them in half a year.

"You kid, just think you have confidence."

"If you are allowed to go abroad, you might do something wrong and turn against the motherland." Zhao Hong said what he wanted to say. If he was allowed to go abroad, he would definitely be a troublemaker.

"Don't worry, I won't target the motherland even if I die."

"After all, I am of Chinese descent, so there is no way I could target the motherland."

He won't even beat him to death. He has seen the humiliating history recorded by China, so he must not forget the national humiliation. This original intention will not be forgotten.

Technical analysis, seeking to revitalize China's science and technology.

It is a goal that he has to achieve in his life.
