Attitude control system, after Zhang Xingyang returned to the Rocket Academy.
Initial development was completed in less than a month.
A series of tests were conducted on a simulated rocket flight platform, and both the sensitivity and accuracy far exceeded the automated attitude control system on previous rockets.
Of course, these are not without cost, as a necessary price.
The newly designed automated attitude control system is half the size and nearly double the weight of the previous one.
In past rocket designs, such a heavy and complex automated attitude control system would be almost like a burden.
Because whether it is the compression of the load weight due to the increase in weight or the increase in the complexity of the control system, the cost increases.
These are difficult for traditional rockets to withstand.
But with reusable rockets with stronger thrust, these problems are not a big problem.
Because the thrust is stronger, this increase in weight can be ignored.
Also because the rocket is recycled and reused, the cost of a single use is greatly reduced. Averaged over each launch, the cost of the automated attitude control system is nothing.
In this way, the development work of the 110-ton liquid oxygen and kerosene rocket engine began.
It took more than a year, and under Zhang Xingyang's unparalleled advancement speed, the research and development of the new recyclable rocket was basically completed.
In the rocket segmented assembly center, the first rocket that will be officially 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 goose sending a message, after all, the new recyclable rocket is an important task.
It means launching and constructing low-orbit satellite communication systems and launching communication satellites.
As for the role of communication satellites, in today's era of booming Internet, compared with ancient letters, the amount of information transmitted is only greater.
Therefore, the recyclable rocket that transports communication satellites is equivalent to the swan geese that transmitted information to distant places in ancient times.
It was named Hongyan out of this consideration.
"The Hongyan-1 verification rocket is now undergoing final assembly work."
"According to the current progress, the final assembly will be completed in about two weeks."
The person in charge of the Rocket Segmented Assembly Center is named Chen Qinghua, and he is now quite old.
He is an aerospace veteran who has been engaged in aerospace since the domestic aerospace industry was just starting in the 1950s and 1960s.
A generation older than Zhang Xingyang's father, he is now approaching the age of retirement.
Zhang Xingyang still respects such an old man who has made significant contributions.
"Mr. Chen, thank you for your hard work. You have to stay up late and work with us." Zhang Xingyang was a little embarrassed.
"Hey! Where are you now!"
Chen Qinghua is much more free and easy, saying that such a job is nothing at all:
“I think back when I first joined, my normal work would be working for days and nights!”
“The intensity of work now is far worse than what we had back then!”
Although he is already gray-haired, Chen Qinghua still shows the passion of the older generation of astronauts in their work!
"Actually, I never thought that I would be able to see such a miracle in my lifetime!"
Miracle.
Indeed, for Zhang Xingyang, who comes from the future, a rocket like this is nothing. It is to the extent that a more capable college student can design and manufacture it by himself.
But for the Chinese at this time.
Whether it is a high-thrust liquid oxygen kerosene engine with a thrust level of 110.
It is better to directly connect 11 such high-thrust engines in parallel as the propulsion system of the first-stage rocket.
They are all dream designs that the older generation of astronauts can only imagine in their minds.
"These are nothing,"
"Uncle Chen, please take good care of yourself,"
"We can see more space miracles belonging to us in the future!"
Zhang Xingyang said as he watched Chen Qinghua continue to rub the shell of the rocket, which was cold and yet extremely hot in his eyes.
Whether it's manned spaceflight that at this point seems like it's still going to take years of hard work.
It is still an autonomous space station that seems to need another twenty years of hard work.
In Zhang Xingyang's eyes, everything will be displayed in front of everyone at a much faster speed than before.
"Xiao Zhang, with your good words, I will definitely 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 towards life of many older generation aerospace or military system workers.
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 sacrificed their youth, their health, and even their lives in anonymity.
The purpose is for this country to be able to gain a firm foothold in today's brutal international competition.
"'Hongyan' is a good name and has a good meaning."
"Did your institute figure it out yourself?"
Chen Qinghua was a little curious about who recommended such a good name.
The swans fly 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 was named by Mr. Chen Zhongyan after he learned that we had not yet named the new recyclable rocket."
"The old man blurted out, 'Hongyan passes the message'."
"Then we all thought the name 'Hongyan' was a good one, 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 recyclable rocket that Zhang Xingyang mentioned before.
After learning that the rocket's research and development work had been basically completed, Chen Zhongyan was surprised and asked if the rocket had been named.
Then the scene that Zhang Xingyang just talked about appeared.
"It's the name that Brother Chen chose. It's no wonder."
"He has a lot of old school knowledge."
As both old men who have witnessed the construction of the aerospace system from scratch, Chen Qinghua and Chen Zhongyan are naturally very familiar with each other.
After learning that the name was given by Chen Zhongyan, he showed an expression worthy of him.
When they worked together, Chen Qinghua knew that Chen Zhongyan had a strong foundation in old school.
As for the origin of Brother Chen, it involves a relatively long past event.
"Mr. Chen, this rocket test launch is not just a test launch of a new model of rocket for us."
"There will be many projects involved in the follow-up, so you must not let everyone be careless."
"We must do our best in all aspects of quality management."
"There can be no mistakes at all."
Zhang Xingyang couldn't help but warned him again.
Although he did not know about 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, naturally would not be careless.
"Don't worry, we will definitely conduct comprehensive and detailed inspections before the rocket leaves the factory, so that there will not be any problems with the rocket during launch."
Hearing Chen Qinghua's assurance, Zhang Xingyang felt a little relieved.
As long as this rocket test launch is successful, the construction of low-orbit satellite communication networks can also begin.
This will also be one of the few great opportunities for this country to overtake in corners!
