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

In less than a month, the initial development was completed.

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

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

The newly designed automated attitude control system is half the size and nearly double the weight of the previous one.

If it were in the design of rockets in the past, such a heavy and complex automated attitude control system would be almost the same thing as a burden.

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

These are all things that traditional rockets are difficult to withstand.

But with a recoverable rocket with stronger thrust, none of these problems are a big deal.

Because the thrust is stronger, you can not care about this increase in weight.

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

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

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

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

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

Take the meaning of the ancient Hongyan book, 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.

In today's era of vigorous development of the Internet, the role of communication satellites is only greater than that of ancient letters.

Therefore, the role of the recyclable rocket that transports communication satellites is equivalent to that of a wild goose that transmits information to distant places in ancient times.

It is named Hongyan precisely for this consideration.

"Hongyan-1 verification rocket, and now the final assembly work is underway."

"At the current pace, there are about two weeks left to complete the final assembly."

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

It is an old aerospace industry that has been engaged in aerospace work since the beginning of the aerospace industry in China in the fifties and sixties.

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

For the old people who have made significant contributions in this way, Zhang Xingyang still respects them very much.

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

"Hey! That's where it goes! ”

Chen Qinghua is much more free and easy, saying that this kind of work is nothing at all:

"I think when I first participated, I worked for a few days and nights in a row!"

"The intensity of the work now is far worse than when we were then!"

Although he is already gray-haired, Chen Qinghua still shows 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!"

Marvel.

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

But for the Chinese people at this time.

Whether it is a high-thrust liquid oxygen kerosene engine with a thrust of up to 110 class.

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

They all belong to the older generation of astronauts who can only imagine in their minds, dream designs.

"None of this is nothing,"

"Uncle Chen, take good care of your health,"

"We will be able to see more of our space miracles in the future!"

Zhang Xingyang looked at Chen Qinghua and said as he kept rubbing his hand against the rocket shell that was cold and extremely hot in his eyes.

Whether at this time it looks like it will take years of hard work in manned spaceflight.

Or it looks like an autonomous space station that needs to be trained for another twenty years.

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

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

Chen Qinghua is also very free and easy, and he has no taboos about his 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 be able to stand again among the nations of the world.

Many of them have given their youth, their health, and even their lives in silence.

In order for this country to be able to stand firm in today's brutal international competition.

"The name 'Hongyan' is good, and the meaning is very good."

"You guys figured it out on their own?"

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

The wild goose entered space and transmitted a message between heaven and earth.

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

"It was the name given by Mr. Chen Zhongyan, after learning that we have not yet chosen a name for a new recyclable rocket."

"The old man blurted out, 'Hongyan Biography'."

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

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

Chen Lao 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 there was the scene that Zhang Xingyang just said.

"Second Brother Chen's name, then it's no wonder."

"He has a lot of old learning."

As old men who have witnessed the construction of the space system from scratch, Chen Qinghua and Chen Zhongyan are naturally very familiar with each other.

After learning that it was Chen Zhongyan's name, he showed an expression worthy of him.

When they worked together back then, Chen Qinghua knew that Chen Zhongyan had a deep foundation in old learning.

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

"Old Chen, this rocket test launch is not just as simple as a new model rocket test launch for us."

"There are a lot of projects involved, so you must not let everyone be sloppy."

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

"There can't be a single mistake."

Zhang Xingyang couldn't help but tell again.

Although he does not know the follow-up satellite communication network project of the recyclable rocket, Chen Qinghua, as an old man who has worked in the aerospace system for decades, will naturally not be sloppy.

"You can rest assured that we will definitely conduct a comprehensive and detailed inspection before the rocket leaves the factory, and we will not let the rocket have the slightest problem when it is launched."

Hearing Chen Qinghua's assurance, Zhang Xingyang put his heart down a little.

As long as the rocket test launch can be successful, the construction of a low-orbit satellite communication network can also begin.

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