A big country of aerospace with black technology

Attitude control system, after Zhang Xingyang returned to the Rocket Research Institute.

In less than a month, initial development was completed.

On the simulated rocket flight platform, a series of tests were carried out, and both the sensitivity and accuracy far exceeded the automatic attitude control system on the previous rocket.

Of course, these are not without cost, as a necessary price.

The newly designed automatic attitude control system is half the size of the previous one, and its weight has almost doubled.

If it is in the past rocket design, such a heavy and complicated automatic attitude control system is almost a burden.

Because whether it is the compression of the weight increase for the load weight or the increase in the complexity of the control system, the cost increases.

It is difficult for traditional rockets to bear.

But with more powerful recoverable rockets, none of these issues are such a big deal.

Because the thrust is stronger, you can ignore this weight increase.

Also because the rocket adopts the method of recycling and reuse, the cost of a single use is greatly reduced. On average for each launch, the cost of the automated attitude control system is nothing.

In this way, the development of the 110-ton liquid oxygen kerosene rocket engine began.

After more than a year, under Zhang Xingyang's unparalleled propulsion speed, the research and development of the new recoverable rocket was basically completed.

In the rocket segmented assembly center, the first rocket that is about to be formally launched for experimental launch is being assembled.

The official name of the new recyclable rocket is Hongyan-1.

Taking the meaning of the ancient swan geese passing the letter, after all, the important work of the new recyclable rocket.

It is to launch and build a low-orbit satellite communication system and launch communication satellites.

The role of communication satellites, in today's era of vigorous Internet development, compared with ancient letters, only transmits a greater amount of information.

Therefore, the recyclable rocket for transporting communication satellites is equivalent to the swan geese that transmitted information to distant places in ancient times.

It was named Hongyan because of this consideration.

"The Hongyan-1 verification rocket is now in final assembly."

"According to the current progress, the final assembly will be completed in about two weeks."

The person in charge of the rocket segmental assembly center is named Chen Qinghua, and he is not young now.

It is an old aerospace company that has been engaged in aerospace work since the aerospace industry just started in the 1950s and 1960s.

He is a generation older than Zhang Xingyang's father, and now he is about to retire.

Zhang Xingyang still respects the old man who has made great contributions in this way.

"Mr. Chen, thank you for your hard work, you still have to stay up late at work with us." Zhang Xingyang was a little embarrassed.

"Hi! This is where!"

Chen Qinghua is much more free and easy, saying that such a job is nothing at all:

"I think back when I first joined, I normally worked for days and nights!"

"The current work intensity is far worse than ours at that time!"

Although already gray-haired, Chen Qinghua still showed the pride of the older generation of astronauts in their work!

"Actually, I really didn't expect to see such a miracle in my lifetime!"

Miracle.

Indeed, for Zhang Xingyang from the future, such a rocket is nothing, it belongs to the level that a powerful college student can design and manufacture it by himself.

But for the Chinese people at this time.

Whether it is a high-thrust liquid oxygen kerosene engine with a thrust of 110 levels.

Still, 11 such high-thrust engines are directly connected in parallel as the propulsion system of the first-stage rocket.

All belong to the dreamy designs that the older generation of astronauts can only imagine in their minds.

"It's nothing more than that,"

"Uncle Chen, take care of yourself,"

"In the future, we will be able to see more space miracles that belong to us!"

Zhang Xingyang watched as Chen Qinghua kept rubbing the rocket's ice-cold but extremely hot shell in his eyes and said.

Neither at this point does human spaceflight look like years of hard work.

It still looks like an autonomous space station that needs another 20 years of hard work.

In Zhang Xingyang's eyes, everything will be displayed in front of everyone at a faster speed than before.

"Xiao Zhang, with your good words, I will live a few more years!"

Chen Qinghua is also very free and easy, and has no taboos about his own life and death.

This is also the attitude of many older generation aerospace or military system workers towards life.

They are not afraid of death, the only thing they fear is that their own death is worthless.

For this ancient country to once again stand among the nations of the world.

Many of them gave their youth, their health, and even their lives in obscurity.

The purpose is that this country can gain a firm foothold in today's brutal international competition.

"'Hongyan' is a good name, and it has a good meaning."

"Your research institute figured it out by yourself?"

Chen Qinghua was a little curious about who recommended such a good name.

Swan geese go into space and send messages between heaven and earth.

As the main launch vehicle of the low-orbit satellite communication network, the name Hongyan is really appropriate and has a national style.

"It's the name given by Mr. Chen Zhongyan, after learning that we haven't named the new recyclable rocket yet."

"The old man blurted out, 'The swan geese pass on the book'."

"Then we all thought the name 'Hongyan' was a good name, so we named this model 'Hongyan No. 1'."

Some time ago, Zhang Xingyang was discussing the construction of the Beidou navigation system with Mr. Chen.

Mr. Chen asked about the progress of the high-thrust recoverable rocket that Zhang Xingyang mentioned earlier.

After learning that the research and development of the rocket had been basically completed, Chen Zhongyan was surprised and asked if the rocket had been named.

Then the scene that Zhang Xingyang just said happened.

"Second brother Chen chose the name, so it's no wonder."

"He has a lot of old school background."

Chen Qinghua and Chen Zhongyan are naturally very familiar with each other as old people who have witnessed the construction of the aerospace system from scratch.

After learning that Chen Zhongyan chose the name, he showed an expression worthy of him.

When they were working together, Chen Qinghua knew that Chen Zhongyan had a solid foundation in old school studies.

As for the origin of Second Brother Chen, it will involve a relatively long past.

"Old Chen, this rocket test launch is not just a test launch of a new type of rocket for us."

"There are still many projects involved in the follow-up, so you must not let everyone be sloppy."

"We must do our best in all aspects of quality management."

"There can be no slightest mistake."

Zhang Xingyang couldn't help exhorting him again.

Although he didn't know about the follow-up satellite communication network project of the recoverable rocket, Chen Qinghua, as an old man who had worked in the space system for decades, would naturally not be sloppy.

"Don't worry, we will definitely conduct a comprehensive and detailed inspection before the rocket leaves the factory, so that the rocket will not have any problems during launch."

Hearing Chen Qinghua's assurance, Zhang Xingyang relaxed a little.

As long as this rocket test launch is successful, the construction of the low-orbit satellite communication network can also start.

This will also be one of the few great opportunities for this country to achieve corner overtaking!
