A big country of aerospace with black technology

Longteng Group is now the world's leading supplier of carbon fiber and new materials.

Many people find it difficult to believe that this small business almost went bankrupt eight years ago.

In a few years, it will transform into a material supplier that is number one in China and among the top in the world.

When it was still called Factory 703, there were only a few hundred people including employees who were furloughed and furloughed.

But now, there are at least 30,000 workers in the large production base in the east alone.

Counting all administrative, R\u0026D, and production personnel, there will be more than 50,000 people!

In China, this is already the scale of a large enterprise.

However, due to various reasons, Longteng Group is still a small and micro enterprise during registration.

To a large extent, it is because the company has developed too fast and expanded too fast.

Many problems also arise in this process.

First of all, there is the issue of the person at the helm of the group.

Three years ago, someone suggested that Hu Deming was not suitable to be the general manager of such a group.

At that time, it was Zhang Xingyang who overcame all objections and allowed Hu Deming to continue as general manager.

But now, Zhang Xingyang also has some doubts about whether the old man Hu Deming can still control such a behemoth as Longteng Group.

The second problem is corruption that has occurred before.

This is also a common problem that occurs in any large group.

In the process of rapid expansion, there are layers of structures between different departments, and it is easy for things to go unsupervised.

As a group with an annual revenue of tens of billions, if you miss a little bit, it is a huge sum of money for an individual.

The third question is also the most troublesome for Zhang Xingyang.

The increase in production scale has brought about a decrease in production quality!

And it is the core rocket engine materials business of Longteng Group!

A glimpse of the leopard shows that the group's quality supervision system has already had big problems.

Zhang Xingyang even wondered whether they still adhere to the double return to zero system that he had always emphasized before? !

Technology zero and management zero have been regarded by Zhang Xingyang as the two red lines and lifelines of the aerospace industry since the accident many years ago!

For so many years, there have been no aerospace accidents, which largely depends on these two items.

If there had been corruption before, Zhang Xingyang would have been able to turn a blind eye to a certain extent.

So the rocket engine quality issue really touched Zhang Xingyang's bottom line!

Rocket recycling and maintenance plant, fifth workshop.

"Dean Zhang, why are you here?"

The person in charge of the rocket recycling and maintenance plant is Yang Zongcheng, an old employee of the former 112 Rocket Engine Factory.

He was still a little surprised when he saw Zhang Xingyang coming.

After all, there is nothing important in the recycling and maintenance plant. They usually just test the recycled rockets. If there are any problems, they usually replace the parts directly.

There isn't much highly technical work.

So on weekdays, few people come here.

It's basically a retirement home.

"Let's see how the rocket maintenance work is going." Zhang Xingyang looked up at the rocket in the factory and said.

"Is this a rocket that just returned from the South China Sea?"

Zhang Xingyang pointed to one of the rockets and said.

Although to outsiders, these rockets all look exactly the same, in the eyes of professionals, they can still see the differences between them.

"Yes, it just arrived at the port two weeks ago."

Although Yang Zongcheng didn't know the reason for Zhang Xingyang's question, he still said it quickly.

The rocket recycling and maintenance plant is located in the seaside port area. It is also to make good use of sea transportation to transport rockets.

"Has the maintenance been completed?" Zhang Xingyang asked immediately:

"Has the test report come out?"

At the rocket recovery site, Zhang Xingyang discovered a problem with one of the engines on the rocket propulsion platform.

However, in order to understand clearly which links in the entire system had problems, Zhang Xingyang did not make any announcement, but hid the matter.

"This is its maintenance report." Yang Zongcheng was quite serious about his work. After handing the report to Zhang Xingyang, he said:

"During the maintenance process, we found that there seemed to be a problem with one of the engines, and the fuel flow rate was too slow."

"The specific cause has not been discovered yet, but we have replaced an engine."

Zhang Xingyang nodded, but didn't say anything, but looked at the test report.

He actually already roughly knew the reason for the problem Yang Zongcheng mentioned.

When the engine is working, the temperature detection system detects that the temperature is too high, and the control system will naturally reduce the flow rate to keep the temperature within a certain range to ensure the safety of the rocket.

Zhang Xingyang skipped most of the rocket inspection and focused on the propulsion system.

There are no problems with most parts and engines.

Only that one engine had a problem with reduced flow.

"After you dismantle the engine, where do you put it?"

After reading the test report, Zhang Xingyang said calmly:

"Take me over there and have a look."

It has to be said that Yang Zongcheng has worked in the aerospace system for many years, and his compliance with various regulations is still very high.

Even the rocket engines that have been dismantled and entered the scrapping process are still neatly placed in a warehouse.

"This is the engine that was removed from that rocket." Yang Zongcheng found the problematic engine according to the number.

After opening the wrapped oilcloth, Zhang Xingyang squatted down and looked at the carbon fiber of the engine tail nozzle.

From time to time, he would reach out his hand to poke and pinch.

Although Yang Zongcheng couldn't tell the difference between this engine and other engines in the tail nozzle.

However, he thought that Zhang Xingyang naturally had his own deep meaning in doing this.

So I got closer and wanted to take a look.

After watching it for a few minutes, Yang Zongcheng didn't notice anything different.

"Dean Zhang, is there something wrong with the tail nozzle?"

"No problem. This engine has been packed for me. I will take it away today."

Zhang Xingyang stood up and said to Yang Zongcheng.

Yang Zongcheng didn't think there was anything strange. This kind of thing had happened before.

Most of them found that there are some possible modifications to the engine and took it back to study.

"Do we need to arrange a vehicle?" Yang Zongcheng asked.

Compared with rockets, a single rocket engine is not huge, and even a small truck can pull it.

"You are responsible for transporting it to the airport, and then it will be airlifted back to the institute."

The dry weight of the YF-110 liquid oxygen kerosene engine is only more than 500 kilograms, and the aircraft does not take up much room for air transportation.

In order not to waste time, Zhang Xingyang chose to let it fly back with him.
