A big country of aerospace with black technology

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

Because Mr. Chen, as the number one old man in the aerospace system, is familiar with all parts related to aerospace.

Zhang Xingyang directly mentioned the difficulties 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. We can only conduct a little bit of experimentation ourselves."

"There have been a lot of problems. This time I asked you to borrow the supercomputer to help solve the problems here as soon as possible."

As soon as Chen Zhongyan heard it, he understood that the rocket developed by the Rocket Research Institute must not have adopted the traditional rocket design scheme, but he did not know what scheme they used.

However, Chen Zhongyan was also very measured, and he didn't ask too much if Zhang Xingyang didn't say anything.

"Aren't there any foreign countries that can be used as references?"

Because domestic scientific research capabilities are not particularly developed at this time, in many respects we are crossing the river by feeling the bear and the eagle sauce.

Of course, because of this later, there was a saying that the rabbit crossed the river by groping the eagle sauce, and then touched the eagle sauce bald.

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

Zhang Xingyang recalled the database in his mind and said:

"In the legacy left by Mao Xiong, there is indeed technology related to this aspect.

They have used a similar propulsion system on the N-1 rocket that is still at the Baikonur Cosmodrome Center, and the Energia that is also at the Baikonur Cosmodrome Center has also used immature rocket recovery technology. "

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

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

The 30 engines are also adopted in the central layout scheme, with 8 engines arranged in the inner circle and 24 engines arranged in a circle on the outer circle.

There are more references to the rockets developed by the Rocket Research Institute.

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

It can be regarded as the first batch of rockets that actually used recyclable and reuse technology, but it stagnated because of the breakdown of research and development funds caused by the disintegration of the bear.

The fruits of countless painstaking efforts made by these Maoxiong scientific researchers lost their value along with the disintegration of the alliance with mixed reputations.

I can only remember the hustle and bustle of the past under the sunset of the Baikonur Space Center day after day.

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

As a senior astronaut, Chen Zhongyan is naturally not very unfamiliar with these once-flashy rockets, but he is not as clear about technology as Zhang Xingyang.

"Then have you considered referring to their system?"

Mr. Chen asked, the relationship between the country and these countries that were formerly affiliated with Maoxiong was pretty good during this period, and if they could afford enough money, they would even be able to sell some top-secret things.

"Although their technology has certain reference value."

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

It's not that Zhang Xingyang is arrogant and looks down on Mao Xiong's previous technology.

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

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

This is also an important reason why a total of ten N-1 rockets were produced and no follow-up launches were carried out. The design and manufacturing process of the rocket was not particularly perfect, and almost all of the manufactured products were defective.

"The N-1 rocket is almost worthless, it's just an industrial defect!"

After listening to Mr. Chen, he raised his eyebrows and jokingly said:

"They can have good people call it 'the most powerful rocket in the world', is it really as bad as you said?!"

This title is indeed a bit bluffing, but Zhang Xingyang's mouth twitched, a little speechless:

"What's the use of a rocket with no real launch capability, no matter how powerful it is?!"

"However, if the Energy and Snowstorm aircraft can be obtained, they can help us avoid a lot of detours."

"Ho!"

"You really dare to think about it. When Mao Xiong built the energy number ten years ago, he spent a sky-high price of nearly 20 billion pounds."

"Even if they don't feel bad about selling their father's land now, it's not something they can win with a small sum!"

The cost of Energia is indeed astonishingly high. Except for the era when all the power of the country was engaged in space competition, it is impossible to see such a big deal.

For future space missions, more consideration should be given to the economics of rockets.

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

If there is no way to get it back at this time, then it will also be buried in the factory building of Baikonur Cosmodrome in 2002.

"In other words, the space shuttle route is actually not as economical as the recyclable rocket route. Don't look at the former Mao Xiong and the current Eagle Sauce are vigorously promoting the development of the space shuttle."

"However, they are still far away from the truly cheap and cost-effective space shuttle. Now every time the Eagle sauce space shuttle flies back, it needs to undergo a major repair, and the calculated cost will even be higher than the price of a one-time rocket."

As one of the top figures in the domestic aerospace system, Mr. Chen can speak in many ways, especially when it comes to deciding the route.

So in order for Mr. Chen to support him in these areas in the future, Zhang Xingyang spared no effort to explain the problems here to him.

"And in terms of safety, the safety of space shuttles is not much higher than that of recoverable rockets.

The entire system of the space shuttle is very complicated, and its anti-redundancy performance is actually very weak, not as simple as a recoverable rocket. "

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

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

"At present, China has not yet made a decision on manned spaceflight, and now is not the time to discuss these."

"At least in China, we must solve the technical problems of manned spaceflight before considering 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 ideas about manned spaceflight, but now is obviously not the time to talk about these.

This time, it is considered a success to be able to obtain a super-computing usage time.

Still try to do a good job in your own country!
