A big country of aerospace with black technology

Moore's Law: The performance of computer processors doubles every 18 months, while the price falls in half.

Decades have passed since Moore put forward this experience, and this law has always been fulfilled.

However, during this period, the domestic computer industry was still very underdeveloped, especially in the field of supercomputing. The most advanced supercomputer in China at this time was the "Yinhe-2" that had just passed the national appraisal four years ago.

However, even this most advanced computer in the country can perform only one billion calculations per second, and it has no advantage over a home CPU thirty years later.

Not to mention being on a par with those supercomputers that run smoothly with billions of billions of calculations and billions of billions of peak calculations.

Of course, these supercomputers, compared with the protein computing unit embedded in Zhang Xingyang's brain, are simply the light of rice grains daring to compete with Haoyue.

In the 22nd century, a brain computer is the same thing as a 21st century cell phone.

Taking the "Xinghe-5" computing unit embedded in Zhang Xingyang's brain as an example, the number of operations per second has reached 10 to the 25th power level.

More than a dozen orders of magnitude more than the most advanced "Yinhe-2" supercomputer at this time.

And its size is also astonishingly small, less than the thickness of a hair.

In terms of computing power alone, Zhang Xingyang's computing power at this time actually exceeds the sum of almost all the computers in the world.

Therefore, as long as he thinks about the tail jet fluid problem in the rocket engine joint experiment, he can get the correct answer in less than a second.

However, Zhang Xingyang didn't really want to give the correct answer to this question to everyone who participated in this experiment.

After coming to this era, Zhang Xingyang has always had a very clear understanding of the role he wants to play.

That is the role of the leader, or one can say the teacher.

A really good teacher will not only teach students the correct answers to questions, but not teach them how to solve the questions.

As the saying goes: It is better to teach a man to fish than to give him a fish!

This principle is also useful in the field of scientific research. It is better to teach them the solution to the problem than to directly give the result of the problem.

In particular, although everyone in the Rocket Research Institute has indeed done a lot of scientific research work during this year.

But the distance from being able to stand alone, many people are actually far behind, whether it is design, control system, or material research and development.

To be honest, if Zhang Xingyang hadn't always been behind them to support them, many things would not have been possible.

So Zhang Xingyang decided to let them solve the problem of the engine exhaust fluid this time.

Of course, Zhang Xingyang didn't do nothing. What he needed to undertake was actually to help Geng Bo and Qiao Yang to carry out verification calculations after they established the tail jet fluid model.

Although the "Galaxy-5" protein chip in Zhang Xingyang's mind can be calculated in less than a second, if he really does this, it will probably scare many people in the Rocket Research Institute.

After all, with the complexity of this model, it would take several years to calculate it simply by manpower.

And if you figure it out in a second, you're either lying or you're not human at all!

Therefore, in order to cover up my seemingly unreasonable computing power in this era, it is necessary to find a way to borrow a supercomputer.

Come to Qiao Yang and the others to design the fluid operation model and conduct computer simulation experiments.

At this time in China, super is a very scarce resource, and not all projects can apply for it.

Generally, only key projects related to national key projects can apply for a certain period of time.

If you only use the name of the Rocket Research Institute, you may be able to apply for the usage time of a supercomputer, but you must queue up.

As for when it will be available, only God knows.

After all, there are too many units in China that need to use supercomputing. The weather forecast field needs to use supercomputing time every day, and there are a lot of military industry fields waiting to use it.

The field of missiles, which is more important than rockets, has always used high-performance supercomputers for simulation experiments.

Therefore, in order to be able to use the supercomputer in advance, Zhang Xingyang approached Mr. Chen who was in charge of the Beidou navigation system.

The development of the new rocket itself is closely related to the Beidou navigation system.

An important task of the new rocket in the future is to be responsible for launching the satellites of the entire Beidou Phase III navigation system.

This is also the reason Zhang Xingyang came to Chen Lao in the first place. This matter is actually related to the follow-up progress of the Beidou navigation system.

Mr. Chen has a great reason to help the Rocket Research Institute gain time to use the supercomputer.

"Old Chen, I still have to trouble you for the super calculation!"

Zhang Xingyang asked Mr. Chen very modestly and sincerely.

"You will really give me a problem. There are only a few supercomputers in China that can check and calculate such confidential projects."

After Mr. Chen drank a cup of Longjing tea, he said with a smile:

"Now all units, those who have such needs, are staring at those supercomputers almost all the time."

"It's really not easy to buy you a certain amount of time."

"Well, the Beidou project team itself has a certain indicator of supercomputing usage time, and we can share some of them with you first."

Because Beidou is the first time to develop a satellite navigation system in China, it has allocated a certain amount of supercomputing time to simulate and verify the status of satellites in orbit.

But Zhang Xingyang knew that this part of the time must be very tight, and it would take a lot of work for Mr. Chen to allocate some of it to the Rocket Research Institute.

"Old Chen, thank you very much."

Zhang Xingyang said with some emotion:

"In fact, we can also apply for a certain amount of supercomputing usage time, but these times are relatively late."

"If you really wait for the supercomputer to line up slowly, it will be difficult to conduct a test launch within next year."

Speaking of the development progress of the new rocket, Chen Zhongyan was also very interested.

Because if there are no accidents, the Beidou Phase I construction project will start next year.

In the first phase of the project, only three orbiting satellites will be launched to form a relatively simple satellite navigation system.

Now I just don't know whether the rocket newly developed by the Rocket Research Institute can be officially put into use during the first phase of construction.

"When will your newly developed rocket be able to be tested? When will it be officially put into use?"

Regarding Chen Lao's question, although Zhang Xingyang is not very convenient to tell some technical details, but related to the construction of the Beidou navigation system, he can still talk about the development progress.
