The history of China's ramjet engine can be traced back to 60 years ago, when the establishment of a special laboratory was officially approved, which directly opened the curtain on the power business of flying missiles, and eight years later, the first ramjet engine was ignited.

Immediately after that, the CF03 ramjet engine was designed, marking the official entry into the ranks of the few countries that have mastered ramjet engine technology.

In the field of scramjet engines, fifteen years ago, the test speed reached Mach 3, according to the plan at that time, the engine should be developed next year at Mach 6, but now the plan has changed, because of the mastery of more efficient hydrogen and oxygen fuel, Mach 10 is more suitable for China.

But the increase in speed also brings a lot of troubles, first of all, the material problem, how to withstand the extremely high thermal load of the hypersonic propulsion system, and to achieve thermal equilibrium, both of which currently need to be solved by a professional.

"Professor Xu. ”

"Here's all we have. A young man stood beside Xu Mang and said respectfully: "There may be a little too much information, but Director Guo asked you to read it slowly, don't worry." ”

"Oh..."

"Alas?" Xu Mang sat on a chair and asked curiously, "Xiaohu, how many people are there in our laboratory? The footprint is huge, as if... There doesn't seem to be anyone, where has everyone gone?"

Xiao Hu said: "It is estimated that they are all working in their respective venues, unless it is time to eat, it is rare to see others, wait two hours to eat, and then you will be able to see people, and you will definitely be shocked." ”

“...”

I'm sorry

Unbelief!

Xu Mang, as the head of the iron baby, killed I don't believe that there are so many people, just now he went to the toilet once, judging from the pit position of the toilet, there are at most fifty people in this laboratory, which is almost the highest value.

Watching Xiaohu leave,

Xu Mang looked at the pile of information in front of him, and suddenly had a headache, good guy... This is thicker than the textbooks added up when I was studying, when will this be seen?

Finished...

It's all fucking over!

However, even if it is over, Xu Mang still has to read them all, scramjet engine does not understand at all, if you want to solve the problem of material and thermal balance, you must understand scramjet engine and become an expert in this area.

According to Xu Mang's own estimates, it will take about a week.

"Ugh..."

"I already knew about replacing the THAAD system with scramjet technology. Xu Mang let out a long sigh, he didn't think about it so much at the time, but he felt that there was a tiger eyeing Sade on the side, which made him feel very unhappy.

"Look..."

"The system... Start Beast Mode!"

"The system... Turn on memory mode!"

[Lack of relevant skills (propulsion technology and aerodynamic skills) identified by the system]

Xu Mang: ???

I...

Groove,

It's really going to be over!

Xu Mang saw the prompt of the system, and felt that life was gloomy, and he never thought that he would not have the skills in this area, and it seemed that he would not be able to go back for a while, and he would need to live in the capital for at least three months.

[Propulsion Technology and Aviation Power Skills Detected, Propulsion Technology and Aviation Power Skills Unlocked]

+1 propulsion technology and aerodynamic skills

+1 propulsion technology and aerodynamic skills

...

It's still half an hour before noon,

As Xiao Hu, who has just come out of the University of Aerospace Science and Technology, is sitting in the office, using professional software to calculate the load of a certain part, and this set of software is developed by Xu Mang, and almost all computers are installed with Xu Mang's software.

"Huh?"

"Little Hu... Has Professor Xu Mang arrived?" a young woman asked curiously, "Is it handsome?"

“...”

"I don't know, but the first time I saw Professor Xu, I felt... He didn't look like a high-level intellectual. "Xiao Hu thinks that people are honest and have no scheming, so he basically has something to say.

"He..."

"He's the kind of guy who says that. Xiao Hu frowned, and said seriously: "That kind of aura that exudes no progress from top to bottom, as long as there is a chair and a table, he can lie on it until the world is destroyed." ”

Hearing Xiaohu's words,

The young woman who was full of fantasies about Xu Mang was very displeased, Xu Mang was her template for choosing a mate, and her husband in her mind was using Xu Mang as a blueprint, and when she heard that someone was insulting her 'husband', she was anxious.

"Oops!"

"Don't talk nonsense... Although I have not met Professor Xu in person, I have seen his photo. The young woman said with a look of longing: "That back photo... It's so handsome! ”

“...”

"I'm sorry... Professor Xu Mang is engaged. Xiao Hu said honestly: "His fiancée is more than a hundred times more beautiful than you." ”

I...

You...

Damn it!

The young woman almost vomited blood, and looking at Xiao Hu's serious appearance, she felt even more angry... It's too shocking, the most important thing to be a man is to keep a trace of fantasy, but this guy specializes in fighting other people's fantasies.

"Alright, alright!"

"Isn't it almost, in case Professor Xu Mang comes in and sees you like this, and no one will make a joke?" a woman in her thirties said helplessly: "We are in the mechanical load department, so don't discuss things about other fields, especially Professor Xu Mang's materials and thermal balance issues." ”

"Sister Tian. ”

"We didn't discuss... Just a casual chat. The young woman said, "By the way, Sister Tian, how long do you think we can complete the Mach 10 scramjet?"

"I don't know. ”

"But now we are facing too many problems... Professor Xu Mang is only here to solve the problem of material thermal balance, and we have not mastered other key technologies, such as double-combustion chamber stamping. The woman said solemnly: "This technology is currently in the hands of the Hopkins Applied Physics Laboratory in the United States. ”

subsequently

The office began to talk about the current dilemma, in fact, the scramjet engine of Mach 5 or 6 had already been completed, but because of the fierce competition in the field and the mastery of better fuel, Mach 10 was suddenly launched.

soon

It's time for dinner.

A large number of people from various departments of the laboratory poured out, and they all headed towards one place, that is, the cafeteria that they loved and hated, and Xiao Hu was also a member of this team, but it was not until he finished eating that he reacted, and he seemed to have forgotten Xu Mang.

"it!"

"It's over, it's over... I forgot to call Professor Xu Mang for dinner. Xiao Hu said nervously: "Brothers... Help me watch, don't let my aunt pour the food. ”

Words fall,

He hurriedly left the cafeteria.

“？？？”

“？？？”

“？？？”

Xiaohu's friends looked confused, he... He just said that Professor Xu Mang, Xu Mang... Wouldn't this Xu Mang be the Xu Mang he knew?

"Professor Xu Mang?"

"No... He came?" said a young man in horror, "When did this come? Why didn't you notice?"

"Nonsense!"

"Do they want to inform you when they come here?" said another young man angrily, "Let's eat." ”

Ten minutes later,

Under the stunned gaze of a group of people, Xu Mang took the meal, refused Xiaohu's invitation to sit together, and sat alone in the corner of the corner, eating lunch by himself.

It's not that he deliberately is cold, it's just that this way can he improve his compulsion.

soon

Almost everyone in the laboratory knew about Xu Mang's arrival, and the two problems he had to solve were not a secret, but the vast majority of people believed that Xu Mang could solve these two problems, and there was no pressure at all.

...

The day's work is over quickly,

Xu Mang stretched his waist and planned to leave his temporary office, but along the way he met a lot of 'colleagues' who came to say hello, a good Professor Xu, of course, Xu Mang responded with a smile, gradually... The muscles in his face cramped.

"How's it going?"

Xu Mang stood on the side of the road, looked at the public electric car, studied for a long time, and finally with the help of laboratory researchers, Xu Mang rode the public electric car and slowly went home.

His Porsche has already let Chen Xi transport it to the magic capital, and he feels angry when he thinks about it, he spent more than 4 million yuan to buy a supercar, but he drove more than 1,000 kilometers and burned the engine oil... It's so humiliating.

"Returning the car successfully!"

Xu Mang returned the car at the designated place and walked into a high-end villa community.

Click,

Open the door

Looking at the empty house, Xu Mang couldn't help sighing, it seems that Cousin Man's family is also very busy... The eldest brother and eldest sister haven't come back yet... No wonder I don't have any children now, what are I so busy, how can I have time to have children.

fire

Cooking rice and cooking vegetables,

As soon as the meal was ready, I heard the sound of a car outside, and then a woman hurried to the house.

“...”

"Xiao Xu?"

"You're done?"

The person who came was Xiao Man's sister-in-law and Xu Mang's sister-in-law, looking at her embarrassing appearance, Xu Mang was particularly helpless, feeling that he was here to be a nanny... And not to work.

"Big sister. ”

"When will my eldest brother come back?" Xu Mang tied his apron and asked with a smile: "Anyway, you don't have any psychological burden, at home... I often cook for Xiaoman, I have long been used to it, and my side business is housewives and men. ”

The eldest sister sighed and said with a bitter smile: "I feel guilty in my heart for letting a scientist of this age cook, if it were known to others, Xu Mang, one of the world's most outstanding physical scientists, was cooking with an apron, I might be scolded to death." ”

"No, no, no. ”

"If you want to scold, you will scold Xiaoman first. Xu Mang said with a smile.

soon

My cousin came back, and when I faced my brother-in-law wearing an apron, I was very confused, but after being confused, I was infinitely satisfied.

My cousin's life is really good, and I don't know what shit I stepped on, so I found a husband like Xu Mang, who is not only knowledgeable, but also has good cooking skills, and is also elegant and easy-going.

At the dinner table,

Xu Mang suddenly received a phone call, it was his old friend Chen Shao, and it was obvious that the evening was ready for the event.

"Xu Mang?"

"It's been arranged, it's clearly arranged!"
