Chapter 675: The Master Just Comes without Hesitation

Beijing North, Haiding, National Space Administration.

In a large conference room, nearly 20 people are conducting technical discussions.

"Recyclable Rocket Technology Seminar".

is the name of this meeting.

The people sitting here are experts and bigwigs in the field of aerospace, and what they discuss is also the most cutting-edge technology.

Recyclable rockets are a big trend. In theory, they can save up to 80% of the launch cost. Moreover, with the advancement of computer technology and communication technology, remote control is no longer so difficult. It is inevitable that this idea will emerge.

However, aerospace is a gamble of technology. If the most thrilling time in the aviation field is the "test flight" of new aircraft.

Then in the aerospace field, it can be understood that every rocket launch is a "test flight", which also means that every attempt at new technology must be extremely cautious.

If a firework is set off, it is not just a matter of how much money is lost. They are a national team, not a private enterprise, and they lose the face of all Chinese people.

In the conference room, some people are wearing work clothes and some are wearing suits. They all frowned, as if they had encountered some problems.

"'Landing on the surface' is too difficult, there is no buffer at all"

"But if we use the 'sea landing' solution to recover, it will be very troublesome. Only large warships can recover large objects efficiently and in a highly organized manner, and our ships cannot sail around."

One person said: "Not to mention the safety of going thousands of miles to retrieve rockets specifically for this purpose, won't the cost go up again?"

China is not like the United States, which has bases and ports for berthing warships all over the world, and has no fulcrum in the Pacific.

If there is a deviation and someone intercepts it, it will not be a loss of face, but a loss of substance.

"Isn't the first island chain broken? The Western Pacific can still be navigated."

"It's still too sensitive. I advise everyone not to fantasize and proceed from the actual situation."

This is China's aerospace.

Dancing with tied hands and feet in a state of blockade, hostility, and isolation.

Not allowed to go to the space station, technology cannot be exchanged, and cooperation cannot be carried out

Still persisting for decades.

"Okay, let's focus on the direction of 'surface landing' first. The most important consideration for rocket recovery is the attitude adjustment problem."

What is recovery?

Let's use this analogy. Light a steel "firecracker" weighing hundreds of tons and watch it accelerate to about 9km/s and rush out of the atmosphere.

Then this thing falls from a height of hundreds of kilometers and must fall straight to the ground. The final landing speed cannot exceed 1m/s.

It's not difficult, right? (See the author's words)

"Director Qiu, you are an expert in engine attitude adjustment. We want to hear your opinion."

Qiu Lixun, director of the research department of a subordinate engine research institute of Aviation Industry Corporation of China, is one of the external experts invited.

Although the difference between aviation and aerospace is as big as that between "second-floor technicians" and "third-floor technicians", it is always necessary to learn from others and apply what they have learned.

Qiu Lixun is the head of the "Bifang Engine" project team and an expert in the aviation field who has made great achievements in the past two years.

They are all national teams, so it is normal to invite them to discuss.

But Qiu Lixun was obviously very tired. He had been called here four times in the past two months, which affected his work rhythm.

I was almost sent knives by people from Rongfei, Xi'an Aircraft, and Shenyang Aircraft!

A large group of aviation industry entities were squatting at the door waiting for the delivery of "Bifang". All the institutes were 007, working in three shifts to mass produce.

He was almost squeezed dry!

And to be honest, the meetings here were always slow.

He understood that these people in aerospace were more cautious than aviation people, but if the technology was not up to standard, no matter how much discussion there was, it would be meaningless.

He secretly decided that this was the last time he would come. In the future, he would just read it but not reply. If he came again, he would be a puppy!

Qiu Lixun rubbed his eyebrows and said:

"I have already introduced the attitude adjustment performance parameters of 'Bifang' to you. It is up to standard in terms of control ability alone, but the principle is too different."

"Several solutions I proposed were also rejected by you. You should think of another way."

In terms of attitude control ability, the fighter engine is naturally more flexible.

The tail jet was pressed, and the leaves fell and flew up!

But fighter engines and rocket engines, although both of them are flamethrowers, have completely different principles.

"Bifang" is an engine within the atmosphere, relying on combustion to heat the air to expand and quickly eject it to obtain momentum. Air is necessary, providing both oxygen and jet working fluid, with "inlet" and "outlet".

In order to adapt to the needs of working outside the atmosphere, rocket engines need to bring their own "oxidizer", just like a syringe. The entire rocket is a reverse Pixiu that can only output but not input.

Qiu Lixun is not bad, he really has no energy to expand into new areas.

Please, let me go back to play "Bifang", Rongfei's people are almost living in my toilet!

Seeing this person who doesn't want to talk, all the experts in the space agency sighed silently in their hearts.

What can be done?

Or should this technology wait a few more years?

They can't set off fireworks in the nature of "experiments" and learn from failures.

If it takes dozens of failures to break through the "recycling" technology, the national team will lose face, so what if the technology succeeds? It's not worth the loss.

So we must ensure that we are 100% sure every time.

A leader sitting in the first seat saw that the atmosphere was a bit tense and took the initiative to smooth things over.

"It's okay, Director Qiu. Let's learn from others and discuss. Whether there is any result or not, we need experts like you to participate."

Qiu Lixun was showing his cards. He was in a relaxed state and waved his hand and said, "What kind of expert am I? Experts just don't have time to come."

The leader laughed and said, "Oh, there are experts in your institute? Be sure to recommend them and we will invite them!"

Qiu Lixun thought of Engineer Zhou, who had worked with him several times and was deeply impressed by him, but he couldn't make up his mind for a while.

The designer of "Bifang" was Zhou Rui. Many people in the aviation field knew about this, but it was confidential information after all, which was considered as the organization's protection for Engineer Zhou.

That person was too sharp. In the new era, everything was not peaceful.

He was not sure whether the Space Administration knew about it. Confidentiality was confidentiality. We couldn't just talk casually because we were all national teams, not to mention that they were not in the same system.

If Engineer Zhou could be invited to hold a seminar, he would have many constructive opinions without directly solving the problem.

Wait

If we can trick Mr. Zhou to Beijing North, can we also trick him to come and take a look!

Since the mass production of "Bifang", Mr. Zhou has never come here once. He invited the big guys to "visit" him every other day, but Mr. Zhou declined.

Only seeing the new people laughing, not the old ones crying, Mr. Zhou has lost interest in "Bifang".

Even if it is the most advanced aircraft engine in the world

Can the space agency trick him to Beijing North?

The more he thought about it, the more reliable it seemed. With Mr. Zhou's personality of tinkering with new things, he should be willing to come to the space agency to take a look.

Since "here we are", it is reasonable to go and see the "Bifang" production line.

He considered: "There is a big guy, I think you can invite him."

"Oh? Director Qiu, what do you say."

He observed the eyes of the crowd and said: "Master Zhou."

When the three words came out, some people showed strange expressions, while others seemed to know something and suddenly realized.

"Master Zhou? Are you talking about Mr. Zhou? I think I saw him on the news this afternoon."

The leader looked at a corner of the conference room and said, "Xiao Hong, I remember the solar cell issue. You contacted that side, right?"

At the edge of the long table, a woman in her twenties, with a long ponytail and no makeup but a beautiful face, pushed her gold-rimmed glasses:

"I only contacted the Fudan Solar Energy Research Institute. Does that person know about aerospace?"

Hot knowledge, as of today, Master Ma has not yet achieved complete recovery. He has only recovered some parts, such as staged rockets and fairings. The closest recovery of the main body exploded three minutes after landing.

But on the Internet, he has succeeded more than a hundred times, and false news has drowned out the real news.

The information related to Master Ma and the comment area are really the hardest hit areas, and blood pressure has risen.

Sometimes a person feels "ZY speech", which is also quite helpless.
