Chapter 448 Did you hear that?

What China can do is concentrate on development.

They are criticized every day for being so backward, and they are so miserable every day. The people are so poor that they cannot even afford tea eggs...

If you don't immerse yourself in development, what else can you do? Are you waiting to be sprayed to death?

This period can be said to be a very active period in the international space field, but China's space agencies are silent.

If Arclight Aerospace had not been beating the world in the field of transportation, people in the country might have been anxious, but even so, some people with crooked mouths have begun to chirp.

However, according to some people's speculation, the reason why China is doing this is because it must be trying to make some big news.

Not to mention, the reason why China’s space agency is silent is that it is indeed holding back its big move.

China has always been like this: talk less, do more.

Since the focus of China's space agency is now on the space station and manned moon landing, other things are somewhat neglected.

This is also one of the reasons why China agreed to Arclight Aerospace’s development of a space plane.

Whether it is building a space station or a manned moon landing project, what is needed are rockets with high thrust and large carrying capacity, so this is the most important task for China now.

Another reason for allowing the Arclight Group to establish the Arclight Aerospace Exploration Company is to test fly space planes and launch satellites. That is, Dong Chen provided the Chinese space agency with a piece of information on high-thrust rocket engines, as well as information on many launch vehicles.

After research by many aerospace experts, it was determined that this information is very valuable and very helpful for China's two current aerospace goals, and even has reference value for future Mars landing missions.

Moreover, it can be understood and manufactured immediately, and it also has a related impact on other rocket engine technologies, which is perfect for China at this stage.

There are some material issues that may not exist yet, but they have reached the final stage and will be successful soon.

Aerospace technology has been blocked by foreign countries for so many years. China has made it to where it is today through its own efforts. Only astronauts like them will know the hardships involved, so the importance of this pile of information is self-evident.

This is why Dong Chen can now travel in space.

At present, China's aerospace agency is basically developing large-tonnage launch vehicles, while Arc Light Aerospace is developing aerospace planes. Currently, there is no conflict between the two parties in terms of launch vehicles.

Sure enough, after Huaguo was silent for a while, some big news immediately came.

The first is that the Long March 5B carrier rocket, prepared to carry the official space station cabin, achieved its first unloaded flight at China's low-latitude coastal launch base.

And the experiment went smoothly, all indicators met the experimental requirements, and the discarded booster and core rocket landed on the sea landing platform obediently.

Then in the next half month, China used these recovered rockets to conduct two, three, four, and five no-load launch experiments, and all the experiments were successful.

This phenomenon shows that China has also mastered the reuse technology of recyclable rockets, and it is more successful and perfect than Musk Aerospace's technology.

Because it is a waste of time to recover the rocket and drop it to the offshore mobile platform, then drag it back to the coastal launch base, assemble it and refill it with fuel.

It launched five times in half a month, and the calculation time is one launch every three days. In addition, the previous set of procedures is very tight, and even if repairs and maintenance are carried out, the time is limited.

Therefore, Huaguo has truly achieved reusability, just like an ordinary airplane can fly again after simple maintenance after landing.

Of course, the equipment loss of a launch vehicle is much greater than that of an aircraft, and this is ultimately due to technical limitations. In theory, reusing it ten times is now the limit.

After ten times, it does not mean that it cannot be used, but the number of uses within ten times, the equipment loss is within the safe value. After ten times, the safety value will drop significantly, so it is not recommended to use it.

However, it can be used ten times with simple maintenance, which is already a huge savings.

Compared with Musk Aerospace's experimental model, which takes a long time to be repaired and is not necessarily cheap, Huaguo's model is undoubtedly ahead of them and has achieved initial success.

Although it seems strange to say it, the repair cost of some things is simply more expensive than the price of making a new one, and it is also troublesome.

Of course, Dong Chen's contribution is indispensable for bringing Hua to the forefront.

Hey, it's all the fault of the PY transaction.

From this, we can see how superior Arc Light Aerospace’s aerospace plane is. According to Arc Light Aerospace’s data, as long as the maintenance is better, it will take ten to twelve years to fly a mission once every two days. no problem.

Immediately after all the experiments were successful, in May 2019, the Long March 5B carrier rocket carried the core module "Tianhe" of the "Tiangong" space station to heaven.

Of course, this time the rocket is brand new. The previous one was reused just to verify the technology. This time it is the official start.

And after the core module goes to space, it will dock with Tiangong-2, which has been officially renamed "Xiangtian", and the renamed Tiangong-2 will officially become part of the Chinese Tiangong Space Station.

Although the design life of Tiangong-2 is only two years, it is normal for a spacecraft to extend its service. If it joins an official space station and performs regular maintenance, it will not be a problem.

And now that we have such rocket technology, maintenance is much more convenient than before.

Dong Chen, as a representative of private aerospace, was also invited there, along with several technical directors or chairman of more successful private aerospace companies, all representatives of China's civil aerospace industry.

Especially Dong Chen was invited to sit with the bosses, but they could only sit in the corporate delegation area.

But there was nothing they could do, because Dong Chen was now the big brother in the civil aerospace field.

What I’m talking about here also includes Big Brothers abroad and around the world.

In fact, both the upper-level bosses and Dong Chen knew why Dong Chen was invited there.

"Xiao Dong, this is our first formal meeting," an old man sitting next to Dong Chen said to Dong Chen with a smile.

"Yes, Mr. Zhao, I used to listen to your guidance on the video. You are quite young in real life, and you are much more powerful than on the video, hehe." Dong Chen said with a smile.

"Haha, you kid, when have I ever coached you? You're still pretty good at coaching us." Zhao Gang said with a helpless smile.

After speaking, he looked at Dong Chen, then patted him on the shoulder and said sincerely, "You did a good job this time. It is precisely because of your information that we can see the core module lift off early today, otherwise We have to wait another month. Moreover, the mature rocket recovery technology also saves a lot of funds, and we can do many other things."

"You don't know how strict foreign countries are in blocking our aerospace technology. For many years, we were not allowed to join the International Space Station. Not only was the United States not allowed, but we were also deceived by Europe. I don't know how much we suffered and lost. How many faces."

"Today, the core module of our own space station went to heaven, and their International Space Station is about to be decommissioned."

"If those old friends who have left can see today and see the rapid rise of our country, they will definitely have two more bowls of rice."

He squeezed Dong Chen's shoulder and said, "Work hard, this world will eventually belong to you young people, and we have to rely on you to realize our previous wishes."

"Yes," Dong Chen nodded, "Yes, Mr. Zhao."

"But you said something wrong."

Such a sudden turn of events occurred, and Zhao Gang was stunned and asked, "Wrong? Which sentence?"

Dong Chen smiled softly and said, "We are not rising, we are just coming back."

"Come back... again?" Zhao Gang muttered quietly, then laughed loudly and said, "Haha... You kid, okay, I'm optimistic about you."

While they were chatting, the staff in the control center were sitting in front of the computer and constantly making mission reports. The scene was filled with a warm atmosphere.

"...The orbit is normal, the speed is normal, and the core module of "Tianhe" is approaching Tiangong-2..."

"...reach the docking position and start the docking process..."

"...Three, two, one, docking successful!"

"The core module of Tianhe and the experimental module of Xiangtian are docked successfully!"

"It worked, we succeeded!"

"Oh, it worked!"

Dong Chen was also very excited in such an atmosphere. Just when he was excited, he heard Mr. Zhao talking next to him. However, because the scene was too lively and noisy, even his super hearing could only hear a small sound. sound.

"Did you hear that, old guys, we succeeded..."
