You say you have an iron will, are you serious?

Chapter 215 I think this job is still a bit challenging
At one o'clock in the afternoon, the Sixth Aerospace Academy, Beijing (No. 11) Research Institute.

The car drove directly into the gate and stopped in front of the office building.

When getting off the car, Zhao Mo saw Director Gao and Director Tan standing in front of the office building to greet them.

Then, when greeting each other, the two of them were very enthusiastic about Mr. Wang, Director Gao was also very enthusiastic about him, and Director Tan obviously had some objections.

Of course, Director Tan just didn't smile and didn't show off his face.

Even so, this is actually an obvious manifestation of having opinions.

"He is a down-to-earth and technical person~"

Zhao Mo didn't pay attention, just smiled politely and shook hands with him.

Those who work in technology and those who work in management are two different types of people.

Technical people are often very straight-forward, one is one, and two is two, and they always admire those whose skills are better than their own. However, managers are different, they are warm and hospitable, and they don't know anything about anything.After all, there are too few people with skills, management skills, and high emotional intelligence, and they are all top-notch people.

If he were pulled by the principal to greet a layman at work, his attitude would only be worse.

Director Tan Kaihua was promoted step by step within the Sixth Academy and has been working on the front line of research and development for a long time. Although he holds the position of "director", he is essentially a front-line scientific researcher. He has overall responsibility for every research and development project.

When we went in for a visit, Chief Engineer Wang gave Zhao Mo a general introduction and a friendly address: "Kaihua has always been the leading talent of our liquid rocket engine. He is talented and willing to endure hardships. Whether he is focusing on research and development or analyzing problems, We never give up until we achieve our goals. It is common to burn the midnight oil and fight many times without sleeping for four or five days. Kaihua has made great contributions to the development of our rocket engine..."

Zhao Mo listened in awe.

Director Tan is only in his forties and belongs to the younger generation of scientists, but like the older generation of scientists, he still contributes silently to scientific research despite difficult conditions, and is almost unknown to outsiders.

In the Qinling Mountains, deep in the mountains, I have been working for more than ten to twenty years. Without the pursuit of scientific research and dedication to the country, it is impossible to persevere.

During the conversation, General Manager Wang also privately mentioned Tan Kaihua's coldness just now and explained to him that the other party had not entered the house several times, and the only time he went back to visit his parents on a whim was that his father died not long after, but the other party was because of the research and development tasks. And the thing about not being able to keep one's filial piety is that the other person is such a persistent astronaut!

Zhao Mo knows in his heart that it is precisely because of generations of scientists who are dedicated to scientific research that our aerospace industry can be independent and fruitful, and our science and technology will usher in major breakthroughs and explosions in the future. What was really discovered on the far side of the moon?

It's easy to say "What are our scientists doing?" It's just a matter of words, but only by doing it can you achieve results!
"...The liquid oxygen and kerosene solution is very mature internationally. Damao's rocket engine is basically based on liquid oxygen and kerosene~"

"This has something to do with the purity of the fuel from Damao. Their kerosene has higher purity and less sulfur content. Unlike America's, the sulfur content is too high and it's easy to coke..."

"...It's a pity that Da Mao won't sell these engines like RD-170, RD-171 and RD-180 to us. We have no choice but to buy copies of Da Mao's RD-120 engines and settle for the next best thing~"

"If a high-thrust engine has performance close to that of the RD-120, it will actually be enough in the next ten years..."

"Where's America?"

"The America F1 engine has not been produced for many years and is already in production. They are currently using Da Mao's RD-180, and they are expected to use this engine in the next ten years."

"..."

"All staged combustion schemes are adopted..."

“What about full-flow staged combustion?”

"No one in the country has put the full-flow staged combustion scheme into practical use. Da Mao tried it once in the 60s, and America tried it once in the early 2000s, but they both failed~"

……

After Director Gao took Zhao Mo and Chief Engineer Wang to visit, he and Chief Engineer Wang left, asking Zhao Mo to join Tan Kaihua's team to do research together.

Tan Kaihua completely pretended that he didn't exist and was busy doing research with his team members. Zhao Mo was watching and learning from the sidelines.

Listening to their conversation, Zhao Mo would interject and ask questions about those doubts from time to time.

In this regard, Tan Kaihua did not refuse to answer because of his coldness. He still answered him patiently.For Tan Kaihua, although he hates Zhao Mo suddenly joining their team to study, he does not hate Zhao Mo as a person. In addition, this is also a requirement from above. Zhao Mo is just eager to learn, so he will try his best to cooperate if he can. .

Of course, only in questions.

Once Zhao Mo wants to get started and study parts and drawings, Tan Kaihua will immediately refuse.

But to Tan Kaihua's surprise, Zhao Mo had no intention of taking action. He just stood by watching, listening, and asking questions, as if he was a spectator.

"It saves me some saliva~"

Tan Kaihua thought secretly and breathed a sigh of relief.

It would be great if Zhao Mo could realize himself. He wouldn't have to be a bad person and it would be easier for him to deal with his superiors.

As for Zhao Mo himself, he is here to be a student and to trouble others. He knew before coming that he would not be treated well, so he had already thought about it. This time he came here to be "honest".

I have to say that on-site learning is hundreds of times better and more practical than textbooks, lectures, and PPTs.After just ten minutes of studying, Zhao Mo felt that he had received more goods than he had done in two or three months before.He knew something deeper, something that cannot be found on the Internet today.

Zhao Mo had no objection to Da Mao's operation and America's saucy operation. He could only say that he was not strong enough and others would look down on him.Of course, to a certain extent, it can also be said that we are so smart that we dare not sell our hair for fear of being stripped of all our hair.

As for the combustion plan, Zhao Mo thought of the Raptor engine of Space Exploration Technology Company, which uses a full-flow staged combustion plan.

As for the fuel, Zhao Mo also knew that later on, "methane" became a popular fuel in the aerospace field as Master Ma made the industry popular.

Methane is not the fuel pioneered by Master Ma, but has been used before, for example, in our country.However, methane was inferior to kerosene in terms of thrust and price, and inferior to hydrogen and oxygen in terms of specific impulse and repeatability, so they gave up. Damao and America also gave up for a while.

Now Zhao Mo knows that the use of methane and full-flow staged combustion cycle are in line with the goal of "recyclability". Compared with kerosene, methane has no coking problem, is easy to clean, and is especially suitable for reuse.

Of course, methane is easy to obtain and exists widely in nature, which is also one of the important reasons.

In outer space, over there on Mars, methane reserves are very abundant.

"Interesting~ I used to think that Master Ma's bragging about going to Mars was simply fanciful, and it was just a gimmick for harvesting leeks. Now I see that the reason why this gimmick can harvest leeks is because it matches his various actions. It looks very good. That’s why it’s professional and highly feasible~”

Zhao Mo thought in surprise.

The day flies by~
Tan Kaihua's team has to work all night again, with no intention of going back to sleep.

Zhao Mo kept watching them at the scene and insisted on seeing them until eleven o'clock. Then he ended today's visit and study. After talking to Director Tan, he took the car back.

In response to his farewell, Director Tan just raised his head and said "Oh", and then lowered his head to look at the drawings again.

Zhao Mo could see that the expression on Director Tan's face had not changed. No matter whether he raised his head or said "Oh", he was frowning in deep thought. It was obvious that he didn't pay attention to what he said at all, and his actions in replying to him were just subconscious reactions. .

Zhao Mo didn't pay attention to this at all. He quickly focused on taking stock of the gains from today's visit and study.

When he got home, after washing up, he turned on his computer, recorded his results, and then read books related to rocket engines for a while. It wasn't until early in the morning that he fell asleep.

The next day, there was class in the morning. At noon, Zhao Mo took a lunch box and packed some food. While eating, he took a car to the Beijing Research Institute of the Sixth Aerospace Academy.

"Isn't it just a short time?"

While loading the food, Yang Chan looked at him speechlessly.

Zhao Mo smiled and said: "Save a little time if you can. I think this job is still a bit challenging. So, just eat alone during this time~"

What else could Yang Chan say?He could only say "Okay" and then waved his hand to signal him to get out of here.

After Zhao Mo left, Yang Chan, who had just sat down to eat, suddenly laughed out loud and murmured to herself: "I'm always so confident~ It's a blessing for me, but others would have listened. I don’t know what to say~”

A bit challenging?
Good guy, this is rocket engine research and development work!
Zhao Mo's work and rest for the next few days were in this state.

On the 20th, at one o'clock, Zhao Mo arrived at the research institute on time again and met Tan Kaihua.

In the past, Tan Kaihua had no expression on his arrival and seemed to be used to it.But on this day, Tan Kaihua was startled by his arrival. Then he raised his hand and glanced at his watch, with a look of surprise on his face.

"what happened?"

Zhao Mo didn't know why and asked immediately.

"Professor Zhao, you have a very strong sense of time~"

Tan Kaihua simply said this and then turned to work.

Zhao Mo was startled, then smiled: "Good guy, are you observing so carefully?"

Afterwards, there was intense and orderly busyness again.

However, today seems really, really different.

When it was almost five o'clock, an urgent voice suddenly came in: "Director Tan, it's bad, the second-stage rocket engine that was tested today exploded~"

There was an uproar at the scene!
After hearing the news, Tan Kaihua stood up suddenly and asked loudly: "What is the specific situation?"

Zhao Mo was also shocked and thought: "Such a big accident? Now they are even more busy~"

What he immediately thought was that Tan Kaihua's team would be even busier than now, because they had to analyze the cause of the explosion as soon as possible in order to investigate other engine products and design plans as soon as possible.

As for the engine explosion, it is relatively not a big deal.

As for aerospace, how can it not explode?
