Technology's opening live broadcast to build rockets

Some media wrote a special report titled "SpaceX is about to send astronauts to space. How far behind is my country's commercial spaceflight compared to the United States?" 》.

The report read: "Today, the technology circle has been flooded with news about SpaceX, rocket recovery, Crew Dragon spacecraft, and return to the ground. These represent the most advanced technologies in the aerospace industry, all developed by a private company, and must not be used. Not to mention, amazing!”

"SpaceX's space technology is very strong, so how far is our country's commercial aerospace industry from theirs? According to the author's understanding, this gap is probably more than 'fifty years'!"

"It is reported that my country's commercial aerospace companies can currently only launch small rockets and send micro-satellites into low-Earth orbit. Large-carrying rockets and spacecrafts are out of the question..."

"Having said this, the author also feels deeply sad, but this huge technological gap cannot be caught up in one or two years. I hope that our country's commercial aerospace companies can also strive to compete and speed up..."

This report was like a machine gun firing across a calm lake, causing countless comments.

Some netizens have a pessimistic attitude: "It's too difficult, there are so many gaps. None of the world's top ten commercial aerospace companies are in China!"

"Yes, people are already planning to go to Mars, and our company is still trying to trick you into using your skin!"

"I don't want to, I don't want to, anyone who wants to go to space in the future will have to go to the United States!"

Others expressed opposition and said: "Our country's aerospace technology has also developed, including rocket recycling and nuclear-powered rockets!"

"That's all the matter of the space agency. Can you, an ordinary person, go to space? We are talking about commercial spaceflight!"

"Can you name a Chinese commercial aerospace company?"

"Don't be so arrogant. I believe in Du Xingyu. With him here, we will definitely be able to go to space!"

…

Outside discussions have not affected the design of the "Xingzhou" space plane at all.

With the joint efforts of the space agency and Xingyao Space Technology, the Xingzhou was designed very quickly.

Its structure is improved on the basic structure of the previous "Shenlong". The Aerospace Science and Industry Corporation still maintains the drawings and construction workshop, so the manufacturing speed is very fast.

"The scramjet engine was successfully developed." On the technology simulator, Du Xingyu spent a lot of energy points and finally completed the most critical scramjet engine.

This scramjet engine is the combined power engine of air turbine engine, ramjet engine and rocket engine that he originally proposed.

Using this engine and switching modes, it can fly smoothly at low altitude, supersonic speed and space.

If the technology matures in the future, the scramjet engine can be directly changed into a nuclear-powered propeller for a nuclear-powered rocket. Of course, the space agency will not agree to cooperate with commercial companies for this kind of project for the time being.

Du Xingyu held a meeting again. He showed the design drawings and said: "Everyone, the drawings are out. Now we are starting to demonstrate and run computer simulations. The parts that have been determined can be manufactured before the launch of SpaceX's manned Dragon spacecraft. , we will complete the construction of the Starship!"

"Ingenious!" Zhang Yan was already intoxicated when he saw the design drawings for the first time.

The dense lines and data were more beautiful in his eyes than the statue of Venus!

"Hurry up and demonstrate, I can't wait!" The experts present immediately started working, studying the design drawings of Du Xingyu's improved scramjet engine.

The manufacturing of the scramjet engine was not very smooth, and problems with materials and precision were encountered during the process.

After Du Xingyu spent hundreds of thousands of energy points and used a technological simulator to solve the problem, the manufacturing was completed.

Next is the testing and assembly of various systems of the aerospace aircraft. It has taken two months to complete these.

There are only three days left before the launch of SpaceX's Crew Dragon spacecraft.

According to Du Xingyu's idea, it is best to publicly launch the space plane before the Manned Dragon spacecraft to gain public attention. This can increase the confidence of China's commercial aerospace companies and replenish their exhausted energy points.

But this idea was only half passed. Both the space agency and Dong Jiangbo thought it would be better not to release the news this time, but to launch the test quietly.

There are many reasons. The space agency believes that aerospace planes are not only spacecrafts, but also an important part of future space armaments.

Think about it, a spacecraft that can fly freely in space will pose a huge threat to enemy satellites and space equipment. If it is launched publicly, it may encounter some "accidents."

In addition, because this is the first launch of Xingyao, Dong Jiangbo is worried that if it does not go smoothly, it will greatly damage the confidence of investors.

Investors are not very optimistic about China's commercial aerospace industry. If the launch fails, not only Xingyao, but also China's other space companies will face tremendous pressure.

Under the interference of many factors, they finally decided to launch the Starship aerospace plane before the launch date of the SpaceX Manned Dragon spacecraft.

If the launch is successful and the Starship flies smoothly in space, then the news will be announced and let the world see it!

If the launch fails, just pretend nothing happened...

"What a pity." Du Xingyu felt a little regretful. If this allowed him to live broadcast, he would at least gain millions of energy points, right?

Du Xingyu himself is full of information, so before launching the Xingzhou, he took time to make a video: "Hardcore UP teaches you how to make a spacecraft!" 》

In the video, Du Xingyu talks about most types of spacecraft currently in the world, and uses animated videos to demonstrate the principles of making spacecrafts. This is a popular science video.

At the end of the video, Du Xingyu said: "With rockets, as long as we have mature spacecraft, sending astronauts or passengers into space is something that is just around the corner."

His words made fans who watched the video start to speculate again:

"Shocked, a certain UP owner who stopped updating for two months has committed suicide again!"

"What do you mean by this? Is there any new aerospace technology emerging?"

"It happens every time, but why is there no live broadcast preview this time?"

"The sense of immersion is very strong, I'm ready to go to heaven!"

"Anchor, what do you think of the new Falcon rocket and Crew Dragon spacecraft that SpaceX is going to launch?"

…

Many people also sent private messages to Du Xingyu, asking when he would start the live broadcast.

In this regard, Du Xingyu only wrote a paragraph on his personal account, saying: "The live broadcast is not certain. If it goes well, the live broadcast may be launched in a few days. Just follow me!"

"Already following, waiting for the show to start!"

"Every time the host broadcasts live, it is a big event, so look forward to it!"

"It should be okay this time."

"I heard that you joined Xingyao Company, is it true?"

Thanks to my cousin from the south for the tip.
