Chapter 298 Full-scale Powertrain Test

The discovery of a new high-temperature superconducting material undoubtedly brought another surprise on top of everyone’s joy. The project members were immediately excited and couldn’t wait to throw themselves into the work.

According to Xu Yuan's arrangement, further experiments were carried out on the newly discovered high-temperature superconducting materials.

Determine its zero resistance and complete diamagnetic determination.

At the same time, we will try to continue research and optimization based on this material.

See if we can improve its performance again.

If the material's zero resistance and complete anti-magnetism can be improved to room temperature, it will be a revolutionary change in the material world and will bring about a radical reform beyond imagination in many industries and science and technology. After all, the reputation of room temperature superconducting materials is too big.

Because it involves the nuclear fusion technology that human civilization needs most, superconducting materials have always been a hot area.

There are countless scientists in the world who are involved in this.

But the technical difficulty is too high.

It is far from comparable to the world's difficult mathematical problems.

The superconducting materials currently known in academia basically require an absolute zero environment to be realized.

There are also very few research results on high-temperature superconducting materials above absolute zero.

Now, by chance, a new high-temperature superconducting material has been successfully synthesized, which will undoubtedly play a very important role in the research of superconducting materials.

However, superconducting materials are no different from other materials, and it is still relatively difficult to achieve further research results.

Not to mention the development towards room-temperature superconducting materials.

In addition, Xu Yuan also did not forget that he is currently serving as the chief designer of the country's new generation of spacecraft.

This problem definitely needs to be solved first.

We’ll talk about the rest later.

At present, the new aerospace materials needed for the new generation of spacecraft have been developed and tested. They will then be used in spacecraft manufacturing, allowing the manned lunar landing project, which had been slowing down, to be accelerated and the lunar landing time can be set as soon as possible.

For this purpose, Xu Yuan must be there to take charge and personally supervise the manufacturing of the Long March 10 and Mengzhou manned spacecraft, as well as the Lanyue lunar lander.

finally.

Decided after discussion.

This aerospace materials research laboratory will temporarily maintain its status quo and will be led by Zhang Jin.

Subsequent research will be carried out on newly discovered high-temperature superconducting materials.

Xu Yuan left for the time being.

Ensure the manufacture of a new generation of spacecraft.

In addition, the entire team has no intention of publishing a paper on this newly discovered high-temperature superconducting material.

Plan to conduct research in secret.

This move doesn't mean much to them except publishing a Nature or Science paper.

More importantly, no one knows how this material will perform in the end.

If we can really develop room-temperature superconducting materials based on this, it is simply unimaginable what will happen. Therefore, when it comes to such an important material project, the necessary confidentiality regulations must be adhered to.

……

end of the month.

Just as Zhang Jin and his colleagues were working on research on high-temperature superconducting materials, Xu Yuan came to the Space Technology Research Institute.

The new aerospace material had been successfully developed, and he originally wanted to tell Chen Jianfang and others the good news and at the same time formulate a research and development plan for the next stage.

But when he arrived at Chen Jianfang's office with familiarity, he found that there happened to be two people sitting inside.

He Luping from the Shanghai Aerospace Technology Research Institute was naturally familiar to him, but he had rarely seen the other man.

Chen Jianfang, on the other hand, was in high spirits. After noticing Xu Yuan, he immediately greeted him with a smile and took the initiative to introduce Xu Yuan.

"Xu Yuan, you came just in time."

"We just talked about some good news. I'll tell you someday."

"This is Academician You Kairong from the Rocket Technology Research Institute, who is responsible for the development and advancement of the Long March 10 carrier rocket."

Xu Yuan immediately understood what was going on and thought it was the Rocket Technology Research Institute.

I am a colleague of Zhu Xuejun in the same hospital.

Because the entire manned lunar landing project is under the responsibility of the Space Technology Research Institute, the Shanghai Aerospace Technology Research Institute, and the Rocket Technology Research Institute. The specific task of the Rocket Technology Research Institute is to complete the new generation Long March 10 manned carrier rocket.

The Shanghai Aerospace Technology Research Institute focuses on the Mengzhou manned space flight.

The Space Technology Research Institute is responsible for the lunar lander.

During this period, Xu Yuan focused all his energy on materials, hoping to develop new aerospace materials as soon as possible.

So I am not too clear about the Rocket Technology Research Institute.

But I have to say, Xu Yuan was a little surprised to hear the good news from Chen Jianfang.

I thought I came here to bring you good news, but how come you all have good news now?

"Hello, Academician You."

So after he looked at You Kairong and greeted him, he immediately said to the others in a mysterious manner:

"Actually, I came here today and I have good news to tell you."

"That's a coincidence." He Luping smiled and waved his hand: "Come and sit down."

Then they sat on the sofa next to each other and talked about aerospace matters while enjoying the food.

"Today's good news was brought by Academician You. Their research on the Long March 10 has made a breakthrough in a difficult problem, realizing the reuse of rockets."

Chen Jianfang did not keep the matter in suspense and directly told the situation the next second.

The voice just fell.

Then You Kairong said modestly: "This is mainly due to the design proposal put forward by Academician Xu." He did not take all the credit for himself.

In fact, what he said was not wrong.

When the Space Office decided on the moon landing project, it pointed out the need to research its own new generation of domestically produced spacecraft.

However, due to the extremely high difficulty of the new generation of spacecraft, the technical progress has not been smooth, making it impossible for the new generation of spacecraft to come out.

It was thanks to Xu Yuan’s joining that the design plan was optimized.

This makes the current progress very rapid.

Xu Yuan nodded upon hearing this: "This is indeed good news."

Rocket launches have always been a money-eater in the development of aerospace, and each launch consumes a huge amount of money.

Therefore, for those small places in the world, even if they want to engage in space research, the actual situation is simply unable to support it.

The Long March 10 is a rocket used for landing on the moon, and its thrust alone is a terrifying number.

It can be called a heavy rocket.

The funding required for each launch will only get more expensive.

If rockets remain disposable and cannot be reused as before, the cost of landing on the moon will undoubtedly be much higher.

Moreover, according to the plan of the Space Office, a scientific research station will be built on the moon in the future.

The number of times the Long March 10 carrier rocket will be used will definitely increase.

Long time ago.

Even if a country is strong, it is inevitably unable to do what it wants.

It was precisely because of this that Xu Yuan deliberately changed the Chang Zheng 10 into a reusable rocket when designing it.

However, despite this, there are still a lot of technologies designed in it, and the fact that You Kairong and his team were able to solve them shows that the entire team's research in the field of rockets is not low.

When You Kairong heard Xu Yuan's praise, the smile on his face became even wider, and he hurriedly said a few more humble words.

He soon remembered that when Xu Yuan just came in, he said that the other party also had good news to tell.

So he started to ask.

"By the way, Academician Xu, you just said you had good news to share. What is that news?"

The voice just fell.

It also immediately aroused the curiosity of Chen Jianfang and He Luping.

They all took over the conversation and echoed it.

"I guess the thing you call good news must be something extraordinary. Tell me what the good news is."

“I’m starting to look forward to it.”

Xu Yuan listened to what they said at this time, but did not keep it a secret.

The corner of his mouth was raised with a faint smile, and the next second he did not speak, but took out two documents from the briefcase beside him and handed them over.

"Take a look at this first."

"…What is this?" Although Chen Jianfang and He Luping were confused, they still reached out and took the document out of trust in Xu Yuan.

Then, together with You Kairong beside him, the three of them checked together.

As their eyes fell on the document, when the three of them discovered that it was a test report result of a material, their hearts suddenly moved and they immediately thought of something.

But then he temporarily suppressed his excitement and continued to calm down and look at the contents of the document.

It takes about two or three minutes.

Only a cry of surprise came from You Kairong's mouth.

"The high temperature resistance is nearly 3,000 degrees Celsius. This data is really amazing."

It was obvious that he was the first one to lose control of his emotions, breaking the original atmosphere.

At this point, Chen Jianfang and He Luping were no longer silent and began to express their surprise at the data in the file.

"The new niobium alloy material is really amazing. It is tailor-made for our next-generation spacecraft. It seems that it will not be long before they come out."

“It’s good news indeed.”

That's right.

What Xu Yuan took out from his briefcase was the test results report of the new niobium alloy material.

Since we are going to tell them this good news, real data will definitely be more impactful than oral narration.

"This new niobium alloy material is something we have just developed and has passed the test. It can be used as a manufacturing material for some core components of the next generation of aerospace vehicles."

“There is absolutely no problem with the data.”

There would definitely be no doubt about Xu Yuan's words, and everyone was certain that the new aerospace material had finally achieved great results.

You Kairong and the other three did not hide the joy on their faces.

Don't be stingy with your praise at all.

"I knew that with your talent in the field of materials, you would have no problem solving aerospace materials. However, you completed it in just a few months, which far exceeded my expectations."

"With new aerospace materials, our manned lunar landing project can be accelerated." "Originally, our institute was still worried about the Long March 10 engine, worried that the existing materials would not achieve the ideal performance. Now we have finally solved this problem."

After listening to what the people present said, Xu Yuan smiled and waved his hand, saying: "This is not my own credit. If it weren't for the assistance and support from Yan University and Qinghua Materials Institute, we would not have been able to conquer new aerospace materials so quickly." He did not forget to mention the help of Zhang Jin and others.

Chen Jianfang then took the opportunity to continue the conversation:
"I have to take some time to thank them. The emergence of new aerospace materials can greatly shorten our lunar landing period."

According to his original expectation, it would take Xu Yuan a longer time to master the new aerospace materials.

Even with the cooperation of other people.

Unexpectedly, the material problem was solved just a few months later.

And the performance of this new niobium alloy material is so excellent.

One can imagine what great surprises the new generation of spacecraft will bring to the world.

Xu Yuan didn't know what Chen Jianfang was thinking at the moment, he just answered with a smile on his face.

"For now, let's focus on the research, development and manufacturing of the next generation of spacecraft. We can thank them later when we have the chance. Right now, they are busy doing experiments."

"Still doing experiments?" Chen Jianfang was startled. "Hasn't the new aerospace material been successfully developed?"

Of course, he had known about the cooperation between Xu Yuan and Yanda School of Materials Science and Engineering for a long time.

It is also clear what the purpose of establishing this laboratory is, which is only to carry out the research and development of new aerospace materials.

Now that a new niobium alloy material has been synthesized, which means the project has been successfully completed, other project members should be able to relax. So why are they still conducting research?

Xu Yuan saw the doubt in Chen Jianfang's eyes, and the next second he said something very calmly.

"Well, during the research and development of new aerospace materials, we accidentally discovered a new high-temperature superconducting material."

"They want to conduct in-depth research on this high-temperature superconducting material."

Whether it is Chen Jianfang, He Luping, or You Kairong, although they all come from the aerospace field, they also know what superconducting materials mean, and they really can't imagine that such a thing can happen.

This also makes Xu Yuan's abnormality in the field of materials even more apparent.

I thought it was amazing that we developed a new aerospace material in a few months, but I didn’t expect there was also a high-temperature superconducting material.

The three of them were completely out of temper and fell silent for an instant, not knowing what to say.

In the end, it was You Kairong who started talking first and expressed his opinion directly in front of others.

"Cough cough..."

"Now that new aerospace materials are available, we will immediately start manufacturing rocket engines."

“It was definitely done in the shortest possible time.”

The voice just fell.

Chen Jianfang and He Luping next to them did the same thing, they both had to speed up the progress that had been delayed previously.

Xu Yuan felt more and more relaxed about this, knowing that according to the current situation, it might be possible to complete the moon landing within two years.

This is much earlier than the expected time previously announced.

that's it.

Faced with such great news, after expressing their opinions, He Luping and You Kairong did not stay any longer.

They soon said goodbye.

It was obvious that he couldn't wait and wanted to go back quickly and start advancing the project progress immediately.

Only Xu Yuan was still standing there. Just as he was about to leave, he was stopped by Chen Jianfang.

"Regarding the development of the Moon Lander, I would like to discuss some details with you."

"Ok."

Since this involves the manufacturing of the Lanyue lunar lander, there is naturally no room for any carelessness.

The safety of astronauts must be absolutely guaranteed.

So Xu Yuan didn't hesitate at all and agreed immediately.

……

With the mass production of new niobium alloy aerospace materials, they will be widely used in the manufacturing of new generation aerospace vehicles. With Xu Yuan in charge, small problems in the process can be quickly solved. Whether it is the Long March 10 carrier rocket, the Mengzhou manned spacecraft, or the Lanyue lunar lander, the progress is proceeding at an extremely fast speed.

However, Zhang Jin and others at Yanda's New Aerospace Materials Laboratory encountered problems in their research on high-temperature superconducting materials.

Although it is certain that this is a new high-temperature superconducting material.

However, the characteristics are not very stable. Even if there is any change in the external ambient temperature, the original anti-magnetism and zero resistance phenomena will disappear.

Not to mention transforming it into room-temperature superconducting material.

However, since Xu Yuan is currently working in several institutes of the China Aerospace Science and Technology Corporation, he has to rush around to avoid any emergencies.

There was no time to continue the research on high-temperature superconducting materials, so they had no choice but to temporarily stop and restart the material project when Xu Yuan was free.

In the blink of an eye, several months passed.

At the Rocket Technology Research Institute, after the efforts of scientific researchers, they finally completed the manufacture of rocket engines using a new niobium alloy.

Xu Yuan was specially invited to watch the first test run of the engine.

The so-called rocket propulsion system test is simply an ignition without launching into space.

This will be used to comprehensively assess and verify the rocket's engine pressurization and delivery, body structure and electrical products.

It can be said to be the ground development test with the most systems, the most complex conditions and the greatest difficulty in the development process of the launch vehicle. It is also a prerequisite for whether the rocket can be ignited and launched.

This shows its importance.

However, as long as all tests are successful, it will also indicate that the Long March 10 is about to mature.

Have the ability to carry out launch missions.

-

2021 12 Month 15 Day.

Wednesday.

It's about ten o'clock in the morning.

Inside the engine test tower of the Rocket Technology Research Institute, the complete Long March 10 rocket propulsion system has been installed in the test tower, waiting for the ignition command to be issued.

In the control command room, Xu Yuan was wearing the same work uniform as everyone else today.

Listening to the introduction of Academician You Kairong next to me.

"This time we are directly conducting a full-scale test run of seven engines. If successful, it will probably break the previous test run record."

You Kairong seemed particularly confident today, and there was no trace of worry in his eyes when he said this.

You should know that under normal circumstances, when testing a rocket propulsion system, only a small number of engines will be ignited at the beginning, not a full-scale event like today.

But since You Kairong dared to do this, it meant that he was confident about today's test drive.

The thought stayed here, Xu Yuan turned his face with a smile on his face, and answered with a little humor:
"For Academician You to be so confident, it seems that the result of today's test run is already determined."

"This is all thanks to the new niobium alloy material developed by Academician Xu, as well as the support of related design plans. Otherwise, we would not have been able to complete the manufacturing of the entire power system so quickly." You Kairong took over Xu Yuan's words and agreed with a smile.

While the two were talking, a staff member came over to make a report.

"Report."

"The rocket propulsion system is in place. Shall we start the ignition?"

You Kairong can be said to have been looking forward to today's ignition test.

Now that we have finally waited until this moment, we will definitely not delay any more.

Without any hesitation, the order was immediately issued to officially start the test run of the Long March 10 power system.

"ignition."

Then, with the end of the countdown, you can instantly see a thick and powerful column of fire spurting out from under the test tower, accompanied by a loud noise and obvious physical vibrations.

The Long March 10 rocket has seven engines arranged inside a five-meter radius, and uses an eight-way accumulator as the first-stage oxygen delivery component, making the rocket's maximum takeoff thrust reach more than 2,600 tons. The test run of such a powerful heavy rocket power system is a huge spectacle.

It's even more impactful than watching a rocket launch.

After all, a normally launched rocket will reach the atmosphere and disappear from sight in a short time.

Although the rocket propulsion system test run did not last too long, the emotions of the people on the scene were still not calmed down after it stopped.

However, You Kairong was extremely concerned about the test data of the power system and had been waiting beside the computer for a long time.

I don't know how much time passed before I heard an engineer report on the full-size engine test run.

"Yuan You."

"All performance indicators of our power system are excellent and have reached the standards for launch."

After shouting this with excitement on his face, the next second, amid the warm applause from the people around him, he quickly handed the result file to You Kairong for review.

Although You Kairong was confident about this test run, he didn't feel completely relieved until he saw the index data on the document.

"We succeeded."

The successful test run of the full-scale power system basically means that the Long March 10 has reached maturity.

The rest of the work becomes very simple.

It is not an exaggeration to say that as long as the rocket is assembled, it can be launched at any time.

of course.

The prerequisite is that the Mengzhou manned spacecraft and lunar lander have also been successfully developed and are ready.

Xu Yuan had a smile on his face at this time and did not forget to congratulate You Kairong.

"Congratulations, Dean You, for successfully completing the development of the Long March 10."

"Thank you."

You Kairong held Xu Yuan's hand and thanked him with a smile.

It is worth mentioning that although this test run was conducted within the Rocket Technology Research Institute and was not reported to the outside world, the Space Technology Research Institute and the Shanghai Aerospace Technology Research Institute undoubtedly received the relevant information at the first time.

Seeing that the Long March 10 was the first to achieve success, this also brought them invisible pressure.

This has significantly accelerated the research and development progress of the Mengzhou manned spacecraft and lunar lander.

Obviously no one wants to be the one that holds them back.

However, the development progress of manned spacecraft and lunar lander is not very slow, so it will not lag behind the Long March 10 by much. I believe good news will be reported soon.

In addition, this also made the Space Office start to get restless and planned to hold another press conference.

The specific launch time of the rocket for the manned lunar landing project has been officially determined, and has been significantly advanced again based on the previously predicted time.

Show the world our progress in the field of aerospace and let everyone know what a great aerospace power is.

One can imagine what kind of bombshell will be dropped on international news when this press conference is held. I believe that at least the public will be very enthusiastic.
