The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Wang Youliang nodded and said, "Okay."

Although he said yes, he was still a little reluctant in his heart.

However, it had been agreed before that if the third test run failed, external assistance would be required.

He had to agree.

So, Chen Kainan and Wang Youliang flew straight to Chang'an.

Wang Youliang was a little depressed along the way.

Chen Kainan knew what the other person was thinking.

He comforted Wang Youliang: "Engineer Wang, we are all working hard for the development of the country's aerospace industry."

"I think personal fame and gain should be put aside."

"Besides, Comrade Zhipeng is not the kind of person who seeks fame and fortune. When the engine of the new heavy-lift launch vehicle is successfully developed, you and your team will have done a great job, and no one can take that away."

Wang Youliang was touched by what he was thinking. He forced a smile and said, "Mr. Chen, I'm not that petty."

"As long as it is beneficial to the development of the country's space industry, personal honor and disgrace are irrelevant."

Chen Kainan nodded and said, "I'm glad you think so."

"When you meet Comrade Zhipeng, ask him for advice with an open mind. I think you will gain a lot."

"Many big names have worked with Zhipeng before, and they all praised his character."

"Comrade Zhipeng is already a true national treasure-level scientist. He never cares about fame, gain or loss when collaborating with anyone. He is always willing to share his knowledge and experience without any selfish thoughts or distractions."

"You'll know once you've worked with him."

Wang Youliang nodded and said, "I know that Comrade Zhipeng has a high moral character and is a very good person."

“I am indeed a little narrow-minded.”

He finally began to reflect on himself.

The plane arrived in Chang'an.

Because Zhang Zhipeng had been contacted before, he specially sent someone to pick me up at the airport.

The person who picked them up at the airport took them directly to Huaxing Group.

After Zhang Zhipeng met Chen Kainan, he exchanged a few pleasantries and then asked, "Is the development of the engine for the new heavy-lift launch vehicle not going smoothly?"

Chen Kainan nodded and said, "Yes, maybe the temperature of the tail flame is too high. None of our previous high-temperature alloys can withstand it."

"On the third test run, the engine only lasted ten seconds before it exploded."

Zhang Zhipeng had actually participated in the development of rocket engines before, and he is now considered a top rocket development expert.

He knew that rocket engines were highly technical.

To develop a high-thrust heavy-duty engine, it is necessary to use new rocket fuels.

Nowadays, the international Big Bear and Eagle launches of heavy rockets basically use liquid hydrogen and liquid oxygen engines.

This liquid hydrogen and liquid oxygen engine is not easy to manufacture.

The main technical difficulty is that the storage temperature of liquid hydrogen and liquid oxygen engines is extremely low!

Hydrogen has a small molecular weight, and engines using hydrogen as fuel have high specific impulse and are pollution-free.

But if you want to store large amounts of hydrogen, you have to liquefy it.

However, the storage temperature of liquid hydrogen is below minus 250 degrees Celsius, almost close to absolute zero.

The difficulty is really high!

The storage environment of liquid oxygen is better, but it also needs to be below minus 150 degrees Celsius.

The storage conditions of liquid hydrogen and liquid oxygen require not only extremely low temperatures, but also extremely high pressures.

Under high pressure and low temperature conditions, a series of problems will arise, including the tolerance of storage devices, working fluid transportation, flow control, injection gasification, etc.

In addition, the combustion of liquid hydrogen and liquid oxygen will also bring about many problems such as high temperature tolerance of the combustion chamber, combustion oscillation and stability, engine working fluid injection, and low-temperature ignition.

If any of the above problems goes wrong, the engine will inevitably have a major accident!

So, this is the main reason why liquid hydrogen and liquid oxygen engines are difficult to make.

This cannot be explained by the fact that high-temperature alloys are difficult to make.

Another challenge is that the density of liquid hydrogen is too low!

The density of liquid hydrogen is one twelfth of that of kerosene!

It takes up a large storage volume and requires huge storage space.

This will not only put pressure on the rocket's own weight, but also increase challenges to the firmness and reliability of the rocket's structure.

The materials used in the engine must not only be resistant to high temperatures, but also to low temperatures!
As we all know, most common metals will quickly turn into powder at extremely low temperatures.

But the temperature of hydrogen burning in oxygen can reach 3300 degrees! At such a high temperature, most materials will be vaporized.

This requires too much from the materials.

If the material problem is not solved, there is no way the engine can be successfully developed.

Another big problem is that liquid hydrogen and liquid oxygen have different freezing points.

The freezing point of liquid oxygen is minus 219 degrees Celsius.

Liquid oxygen and liquid hydrogen, both propellants, must be isolated well enough when stored!

Otherwise, the liquid hydrogen will freeze the liquid oxygen!

Isolating the two is a big problem!
The device for storing liquid hydrogen and liquid oxygen on the rocket can basically only keep warm and has no refrigeration.

But in the engine environment, even with a thermal insulation coating, heating is still inevitable!

Then, the propellant will evaporate, and the containers storing liquid hydrogen and liquid oxygen propellants cannot be closed and must remain in a leaky and pressure-relieving state.

If this is not handled properly, the liquid hydrogen and liquid oxygen are likely to boil, which will seriously damage the engine.

It is precisely because of the above reasons that rocket engines that use liquid hydrogen and liquid oxygen as propellants can only be filled with the two last before takeoff.

However, because the propellant of the liquid hydrogen and liquid oxygen engine is not completely sealed, the low temperature of the propellant may cause air condensation and block the pipeline!

At this time, there is also the danger of explosion due to the impact of ice crystals!

Therefore, before starting the liquid hydrogen and liquid oxygen engine, the air must be cleared, for example by blowing it out with helium.

All of the above problems must be solved before the safe operation of liquid hydrogen and liquid oxygen engines can be ensured...

Of course, after all the above problems are completely solved, we still need to solve the problem of materials!

It is necessary to ensure that the materials used and every link in the engine structure can work normally under the huge vibration when the rocket takes off!
It has to be said that the working environment of a rocket engine is really too harsh.

Zhang Zhipeng and Wang Youliang carefully discussed all possible problems with the rocket engine they were studying.

Zhang Zhipeng believes that Wang Youliang's team has done a very meticulous job.

However, they may have underestimated the huge vibration caused by the operation of the engine, and there are some problems with the structure of the engine.

Of course, there are some other details that need to be resolved.

Chen Kainan sat aside and hardly interrupted.

Chen Kainan is actually also an expert in rockets.

However, he has been in management for a long time.

In terms of professional knowledge innovation, he is a bit behind the times.

This is also the main reason why he dare not easily participate in the discussion.

Chen Kainan was really impressed by the professionalism displayed by Zhang Zhipeng.

He couldn't understand why Zhang Zhipeng could always update his knowledge reserves despite being so busy at work.

And it can actually span so many fields. Seeing that the two had finished their discussion, Chen Kainan smiled and said to Wang Youliang: "Engineer Wang, what do you think now?"

At this moment, Wang Youliang admired Zhang Zhipeng very much.

On his way to Chang'an, he was actually still a little bit skeptical.

Wang Youliang believes in one sentence: Every profession has its specialization!

If you are engaged in research on a certain industry, then you will only have a superficial understanding of other industries.

In this case, it's best not to point fingers or get involved.

Wang Youliang felt that Zhang Zhipeng was involved in too many fields.

Electronics, computer software and hardware, automobiles, communications, materials, aviation, aerospace, and medical care: there is nothing he has not been involved in.

Moreover, he has made great achievements in every field.

Logically speaking, this is extremely abnormal.

Judging from Wang Youliang’s own dark psychology, perhaps many of Zhang Zhipeng’s achievements were plagiarized from others.

Wang Youliang even felt that Zhang Zhipeng had become a university tycoon.

Whoever follows him should forget about achieving results.

This is also the main reason why Wang Youliang has always been wary and cautious of Zhang Zhipeng.

But now, after a deep conversation with Zhang Zhipeng, Wang Youliang was deeply shocked.

He never dreamed that Zhang Zhipeng would be so professional in rocket engines.

Isn’t this too professional?
I have been immersed in the field of rocket engines for decades.

However, after talking with Zhang Zhipeng, he discovered that he actually had shortcomings in many aspects.

Wang Youliang felt a little ashamed.

Wang Youliang said: "Comrade Zhipeng, I'm sorry, I may have misunderstood you in the past..."

He couldn't help but apologize to Zhang Zhipeng.

Zhang Zhipeng smiled and waved his hands, saying, "Nothing! Comrade Youliang, I think our common wish now is to develop a new rocket engine! Right?"

"Don't think too much!"

Zhang Zhipeng said this and patted Wang Youliang on the shoulder.

Wang Youliang said: "I was deeply moved by Comrade Zhipeng's speech today. I feel that my thinking may be constrained by my inherent experience."

“You have given me a lot of inspiration.”

Zhang Zhipeng said: "Comrade Youliang, I think we have achieved each other's success! Haha!"

"Don't worry, I'm just here to help you!"

"This achievement is still yours!"

"Let's work together to quickly build a heavy-lift launch vehicle and verify our own space station. That's the real issue!"

Chen Kainan said: "This is what makes Comrade Zhipeng admirable. In your heart, you have never thought about your own interests. All you think about is the development and progress of the country."

Zhang Zhipeng waved his hand and said, "No, no! Everyone has a utilitarian mindset."

“I don’t think there’s anything wrong with being utilitarian!”

"However, when personal interests conflict with national interests, we must all put national interests first!"

"Now that you are here, don't rush back. Visit our Huaxing automobile factory first."

Zhang Zhipeng accompanied the two to visit Huaxing's smart car factory and let them test drive Huaxing's smart pure electric car.

Chen Kainan exclaimed: "Comrade Zhipeng, you have made great contributions to the development of many of our industries!"

"I never dreamed that our domestically produced cars could become so advanced."

"From now on, there won't be many industries in the Lizard Kingdom that have an advantage over us."

Zhang Zhipeng said: "Comrade Kainan thought, why were we able to destroy all of the other party's advantageous industries in such a short time?"

Chen Kainan said: "It is mainly because of your appearance that the course of historical development has been changed."

Zhang Zhipeng shook his head and said, "Not really!"

“I may have played a small role.”

"But I think the decisive factor is our strong organization and the power of faith!"

"Our country truly cares about the people! It is also able to gather the strength of the whole society and make targeted breakthroughs!"

"It is because of this that we can achieve breakthroughs in one field after another and achieve success in one industry after another!"

"On the other hand, the Lizard Party is dominated by capital. Even the country is controlled by capital and serves capital. Capital is profit-seeking. In order to maximize profits, profit-seeking capital will eventually mess up everything such as innovation and research and development!"

"Because when financial capital monopolizes everything, they don't pay attention to real production. What they pay attention to is capital operation and speculation!"

"We are the only country in the world that is currently working hard on scientific research and applied technological breakthroughs!"

“This is the main reason why we can win!”

"I say this mainly to remind us aerospace workers that all setbacks are temporary!"

"As long as we continue to work hard, we will be able to accomplish our mission and eventually become a leader in aerospace technology from a follower!"

Wang Youliang and Chen Kainan suddenly realized: They then realized that Zhang Zhipeng invited them to visit the factory in order to give some encouragement to the aerospace workers.

It can be said that it is well-intentioned.

On that day, Zhang Zhipeng followed Chen Kainan and went to the capital.

After arriving in Beijing, Zhang Zhipeng immediately plunged into his busy work.

Now, there was a problem for him: all three rocket engines previously manufactured by Wang Youliang's team had exploded during the ignition test.

The most regrettable thing is that there is almost no wreckage left.

Liquid hydrogen and liquid oxygen engines are so terrible that once an accident occurs, the engine will directly disintegrate or even turn into pieces.

It's impossible for you to even study the wreckage to see what went wrong.

Zhang Zhipeng felt a little regretful about this.

However, he didn't have time to hesitate.

He first held a meeting with people from Wang Youliang's team.

He wanted to get a comprehensive understanding of Wang Youliang and his team's previous research.

To do this, he had to look through their design process drawings.

You need to understand every material and every component they use, and understand the structural strength of the rocket engines they develop.

It is obvious that this knowledge cannot produce any results by relying on process drawings or something like that.

But after working for three or four days in a row, Zhang Zhipeng still found some problems that could cause engine failure.

These problems mainly focus on the fact that the structural strength of the components is still a bit lacking.

There's actually nothing wrong with the high-temperature alloys they use.

However, the internal insulation paint they used was not up to standard.

Improvements are needed in thermal insulation coatings.

There is nothing else.

After Zhang Zhipeng found the key to the problem, he began to solve it.

His solution to the problem of structural strength is simple: use more sophisticated production equipment to produce parts, and in order to strengthen the structural strength, the strength of the alloy material must be further strengthened... (End of this chapter)
