"Now the configuration of the rocket is determined, and the current research and development difficulty lies in the propulsion system of the rocket."

Because Chen Lao, as an old man who can count the numbers in the aerospace system, is relatively familiar with all parts related to aerospace.

Zhang Xingyang directly said the more difficult points encountered in the current research and development process:

"Because the technology used this time is different from the past, there is nothing to refer to, so we can only experiment little by little on our own."

"There have been a lot of problems, and this time I asked you to help borrow a supercomputer, in the hope that the problem here can be solved as soon as possible."

As soon as Chen Zhongyan heard this, he understood that the rocket developed by the Rocket Research Institute this time definitely did not adopt the traditional rocket design scheme, but he did not know what scheme they used.

However, Chen Zhongyan is also very measured, and Zhang Xingyang didn't say anything, so he didn't ask too many questions.

"Isn't there anything that can be referenced in foreign countries?"

Because the domestic scientific research capabilities are not particularly developed at this time, they are crossing the river by touching the woolly bear and eagle sauce in many aspects.

Of course, later there was also a saying that the rabbit crossed the river by touching the eagle sauce, and then touched the eagle sauce bald.

"Yes, there is, but the technical reference value is not very large."

Zhang Xingyang recalled the database in his mind and said:

"The legacy of the woolly bear does have technology related to this.

They used a similar propulsion system on the N-1 rocket that they still have at the Baikonur space center, and Energia, which is also at the Baikonur space center, has used a very sophisticated rocket recovery technology. ”

The N-1 rocket is a high-thrust rocket specially developed by Mao Xiong in order to send astronauts to the moon during the space race with Eagle Sauce.

The first stage of the N-1 rocket uses 30 NK-15 engines, capable of providing more than 4600 tons of thrust.

The 30 engines are also centrally arranged, with 8 engines arranged in the inner ring and 24 engines arranged in a circle in the outer ring.

and the rockets currently developed by the Rocket Research Institute, there are more references.

As for the Energy rocket, it originally existed as a launch vehicle for the Buran space shuttle.

It can be regarded as the first batch of rockets to actually use recyclable and reusable technology, but it has stalled due to the breakdown of R&D funds caused by the disintegration of the woolly bear.

The results of countless painstaking efforts by these once hairy bear researchers have lost their value with the disintegration of the alliance with mixed reputations.

One can only reminisce about the hustle and bustle of the past day after day, in the sunset of the Baikonur Space Center.

Until an accident, the factory where the rocket was stored collapsed and its body was buried in the scenery of the past.

As a senior astronaut, Chen Zhongyan is naturally not very unfamiliar with these rockets that used to be hairy bears, but he is not as clear about the technical aspects as Zhang Xingyang.

"Have you considered referencing their system?"

Chen Lao opened his mouth and asked, during this period, the relationship between China and these former woolly bear member countries was not bad, and if they could afford enough prices, they could even sell some top-secret things.

"Although their technology has a certain reference value."

"However, Mr. Chen, the reference value is not very large."

It's not that Zhang Xingyang is arrogant and looks down on the skills that Mao Xiong once had.

In fact, although these rockets have been built, there are many problems, and they are not particularly mature solutions.

For example, after the completion of the design, production, and manufacture of the N-1 rocket, four test launches were carried out, all of which were unsuccessful.

This is also an important reason why the N-1 rocket, which produced a total of ten rounds, did not carry out subsequent launches, the design and manufacturing of the rocket was not particularly perfect, and almost all of the manufactured products were defective.

"The N-1 rocket can almost be said to be worthless, the whole thing is an industrial defect!"

After hearing this, Chen Lao raised his eyebrows and said jokingly:

"They can have good deeds and call it 'the world's most powerful rocket', is it really as unbearable as you say?!"

It's indeed a bit bluffing to say this title, but the corners of Zhang Xingyang's mouth tugged, a little speechless:

"What is the use of a rocket without real launch capabilities, even if the thrust is great?!"

"However, if we can get our hands on the Energy and Buran planes, it can help us avoid a lot of detours."

"Huo!"

"You really dare to think that when Mao Xiong built the Energy Ten Years ago, it cost a sky-high price of nearly 20 billion pounds."

"Even if they don't feel distressed about selling Yetian now, it's not a small amount that can be won!"

The cost of Energia is indeed staggeringly high, and it is impossible to see such a big deal except in that era of space competition.

In the future, space missions often have to consider the economics of rockets.

Of course, Zhang Xingyang just sighed, after all, this thing can be regarded as a witness of an era.

If you don't manage to get it back at this time, it will be buried in the building of the Baikonur Space Center in 2002.

"I'm saying that the space shuttle route is actually not as cost-effective as the recyclable rocket route, don't look at the former woolly bear and the current eagle sauce are vigorously promoting the development of the space shuttle."

"But they're still a long way from a really cheap and cost-effective space shuttle, and now every time the Eagle Sauce shuttle comes back, it has to be overhauled, and the calculated cost is even higher than the price of a disposable rocket."

As one of the leading figures in the domestic aerospace system, Chen Lao can speak in many aspects, especially when deciding the route.

Therefore, in order to allow Chen Lao to support himself more in these aspects in the future, Zhang Xingyang spared no effort to explain the problems here to him.

"And in terms of safety, the space shuttle is not much safer than a recyclable rocket.

The whole system of the space shuttle is very complex, and the anti-redundancy performance is actually very weak, which is not as simple as the recyclable rocket. ”

"You should also know that the Challenger accident ten years ago killed seven people."

Chen Zhongyan naturally understood Zhang Xingyang's purpose in talking to himself about these things, but he also said his thoughts more clearly:

"At present, there is no decision on manned spaceflight in China, and now is not the time to discuss these."

"At the very least, after solving the technical problems of manned spaceflight, we should consider the problems of these two technical routes."

In terms of manned spaceflight, there is still a lot of homework that is lacking in China, and it needs to be made up in many aspects.

Zhang Xingyang is naturally aware of this, although he also has some thoughts about manned spaceflight, but now is obviously not the time to talk about this.

This time, if we were able to obtain the use time of the supercomputer, it was already considered a success.

Let's try to do our job well in our own country!
