I Don’t Want to Win Lying Down

Thermal protection of scramjet engines is one of the most important key technologies. For ordinary engines, it puts forward new requirements on protective materials. The temperature of the hot air flow in the engine flow channel reaches 3,000 K, which is almost 2,700 K The temperature is about 120 degrees, and the temperature of the combustion chamber reaches 3600K.

If only the temperature needs to be solved, Xu Mang won't be allowed to come over. The complex laser wave system, combustion pulsation and vibration in the scram engine can easily prevent the combustion chamber from generating too high a temperature, thus causing damage to the entire combustion chamber.

Judging from the information Director Guo gave Xu Mang, he had also considered using a cooling structure to reduce the temperature, but it would increase the weight and reduce the performance of the engine. Moreover, the special structure of the scramjet engine makes it impossible to apply the cooling mode, which is also very difficult. Difficult to apply on a large scale.

The simplest thing is to change the structure, or improve the performance of thermal protection materials. The team led by Director Guo chose the second direction to improve the performance of materials.

Owing to time constraints,

In addition, Xu Mang's own propulsion technology and aviation power skills are not enough, so he can only make selective breakthroughs, and some technologies need to be solved by himself.

first,

Xu Mang put forward six problems that need to be solved, heat resistance of materials, oxidation resistance, thermomechanical load bearing, corrosion resistance, technical preparation index, and the lightweight of the latter item on the left. The six indexes represent six problem.

Damn...

I made a mistake and overestimated myself. Xu Mang scratched his hair, blushing at the oath he had just made. What's the difference between this and Taibai Mao owed a hundred chapters and said he could pay it off in a year, but now he didn't say a word. ?

Shame!

I'm really blushing for myself! Xu Mang sighed. According to his own calculations, the skill value was actually just right, it was just a matter of spending a little more time, but he forgot that the skill value would be deducted when using the 'Beast Mode'.

Now,

I can only write slowly at the speed of the tortoise, starting from the antioxidant properties...

For antioxidant,

Xu Mang has a wealth of knowledge. According to the characteristics of the scramjet engine, it needs to absorb oxygen from the atmosphere for oxygen-enriched combustion. The high-speed airflow will also produce atomic oxygen because of the shock wave, which directly leads to more serious oxidation.

In terms of thermomechanical loads, due to the uneven distribution of heat flow on the runners, thermal stress is generated, and if the airflow speed is fast, noise loads will be generated... Therefore, the material must not be deformed, so as not to affect the performance of the engine.

Swish Swish Swish,

Xu Mang wrote for more than an hour, and finally wrote down the six questions clearly. At first, he thought there were not many, but now it seems... they are all problems!

well...

I don't want to work hard anymore...or just be a salted fish. Xu Mang slumped on the chair and looked up at the ceiling. In fact, he didn't need to work hard anymore. After marrying a wife who is so good at making money, why should he work hard? Vigorous?

no!

If you die without a dream, isn't life in vain? Xu Mang washed his brains and started working hard again.

just five minutes,

┻━┻︵╰(‵ ′)╯︵┻━┻

Keep upgrading!

Xu Mang picked up a book on propulsion technology and aviation power, covered his face directly, and then sat there and fell asleep.

Propulsion Technology and Aerodynamic Skills +3

Propulsion Technology and Aerodynamic Skills +3

...

A week passed in the blink of an eye,

Xu Mang lived like a ghost all day long, slept like crazy during the day, spent two hours at night cooking porridge on the phone with Xiaoman, and then continued to cover his face with books on propulsion technology and aerodynamics, frantically acquiring corresponding skill points.

this week down,

The effect is still very significant. Through Xu Mang's efforts, he is only 10% away from being proficient in propulsion technology and aerodynamics.

Jingle Bell!

Alert rings,

Xu Mang glanced at the time, it was 8:30...he was late again, maybe Xu Mang was a non-staff person, Director Guo basically turned a blind eye to his being late or leaving early or absent from work for a day, Sometimes, unfortunately, when meeting Xu Mang who was late or left early at the door, he could only smile and say hello to him.

Put on your underwear, wash up briefly,

Xu Mang drove to work, passed by a Golden Arch, went in and bought two breakfasts, and when he came back, he found that the car had a ticket posted on it, and the speed was very fast. To be towed away.

While driving, eating a hamburger, passing through an intersection, suddenly there was a flash in front of him, and Xu Mang looked dazed, as if...he had been photographed.

finally,

Arrived at the work place,

With light steps, he slowly swallowed the building, so as not to die... I met Director Guo.

Xiao Xu?

Just here? Director Guo asked with a smile.

ah?

Yeah! Xu Mang nodded, and said seriously, There's a traffic jam.

...

Come early next time, so there won't be any traffic jams. Director Guo was quite helpless. The person in front of him couldn't criticize at all, and didn't even have the right to point fingers. Yes, come early and basically you won’t encounter big traffic jams.”

Xu Mang nodded, and said with shame on his face, But I can't get up!

...

Then...then... Director Guo didn't know what to say for a moment, looked at Xu Mang awkwardly, and smiled wryly, What's the progress?

Materials?

Soon...Give me another two days. Xu Mang sucked on the soy milk and said absently, Basically, it will be over.

words fall,

He picked up another cup of soy milk and handed it to Director Guo.

Director Guo?

Drink? Xu Mang said with a smile, It's a bribe.

Ahem!

I'm not thirsty...keep it for yourself. Director Guo said seriously: Xiao Xu...it's not that I'm supercilious. You are aware of the situation, but you told me that it will be over in two days?

yes!

What's wrong? Xu Mang asked curiously, Is there any problem?

...

It's nothing... let's go to work. Director Guo nodded and went up to the third floor with Xu Mang.

Arriving at the door of his office, Director Guo stopped suddenly. Looking at Xu Mang's back, he couldn't help but frowned. He felt that this young... seemed to be floating, a little too much, but there was no other way. Think about it, if you have achieved so much at his age, you may float higher, farther and more indulgent than him.

into his office,

Director Guo pondered for a moment, silently picked up the handset of the landline at hand, and called his old friend.

Hello?

Old Yang...your niece and son-in-law seem...not working? Director Guo didn't go into too much detail, and said seriously: Did he encounter some troubles recently? Did he not feel very happy?

What?

Impossible? The uncle was stunned for a moment, and said seriously: Xiao Xu has always been rigorous in his work, and it is impossible for him to say that he is out of state. Even if... With Xiao Xu's self-control ability, he will Get your status back.

...

Old Yang!

Don't be so full of words. Director Guo said helplessly: You don't know Xiao Xu's recent performance. He arrives late and leaves early every day, and sometimes he can't even find anyone. To be honest...it's not like The work attitude Xiao Xu should have.

this time,

It was the uncle's turn to be confused. In his impression, Xu Mang was not like this.

What's going on now?

Ahem!

I called an elder and asked what was going on.

words fall,

The uncle hung up the phone directly, and then called the principal of Fuda University.

In terms of seniority, this is his second uncle.

Hello?

Second Uncle... What is Xiao Xu's work status like at school? The uncle asked curiously: He didn't work in the capital recently, and then I received a call from an old friend who told me... Xiao Xu's work attitude is problematic, he arrives late and leaves early every day, and sometimes he can't even find anyone.

...

That's right! The second grandfather sighed, with a little helplessness in his tone: You must not be deceived by his innocent image, or be delusional because of the media reports, actually... .This bastard's ability to make trouble... oh...

Uncle is completely confused, this...things seem to be getting more and more strange.

Second uncle?

I can't understand a little bit, this... the little Xu you are talking about seems... a little unreal. The uncle said.

You've just come into contact with him. After a long time, you'll know. The second grandfather said, That friend who told you, you don't need to deliberately stare at Xu Mang. The tighter you are, the kid is making trouble. The stronger you are, the more careful you are that the house will be demolished in the end.

In two words - stocking! Second Grandpa said seriously.

stocking?

this...

can this work?

The uncle hesitated for a moment, and asked hastily: Second Uncle...Are you sure? Are you sure you want Xiao Xu to be kept in stock? The project he participated in is not simple!

Do not worry!

There is nothing wrong with listening to me. The second grandfather said indifferently: Don't worry about him, you can't control him... I have been with him for nearly a year and a half, and I can tell you clearly, please Leave him alone.

The uncle opened his mouth, hesitated for a long time, and said, Okay!

correct!

Let your friend ask Xu Mang when the project will end. As long as Xu Mang tells you a time, it's basically close. Second Grandpa reminded.

I see!

hang up,

The uncle called Director Guo directly.

Hello?

Old Guo... Let me tell you one thing. Xiao Xu has such a work attitude. You don't need to talk to him, just let him fend for himself. When the uncle said these words, the whole person fell into an embarrassing state. in trouble.

you...

I'm talking about Lao Yang... Huduzi doesn't have such a guardian! Director Guo's face was full of black lines: This is not a joke... You should know how important this project is!

well...

Anyway, just listen to me once! The uncle asked again: By the way... Did Xiao Xu tell you when it will be finished?

Director Guo hurriedly said: Say it! Two days later, isn't this nonsense?

Ahem!

Maybe he's serious. The uncle said with a wry smile, How about...let's talk in two days?

Director Guo:? ? ?
