Movie black technology

Thermoelectric power generation depends on the temperature difference between the two ends of the material. The slower the temperature difference drops, the longer the sustainable power generation time will be.

"Yeah," Chen Shen also read the data at this time, "The situation is not bad."

"According to the current situation, it is no problem to put this system on the Tibetan Antelope. At that time, in a vacuum environment, as long as the nuclear reactor operates in pulses, the energy supply can be guaranteed."

When the Tibetan Antelope was in space, the nuclear reactor was not always activated.

After all, a nuclear reactor is a super large furnace, and there is no such ubiquitous heat dissipation medium as air in space. Although the heat dissipation material used by the Tibetan Antelope is a systematic technology, it also has limits.

If the nuclear reactor is turned on all the time, the high temperature of thousands of degrees will continue to be generated inside the spacecraft, and only heat radiation will be used to dissipate heat. limit.

You must know that the air intake grille in front of the Tibetan Antelope is specially used to dissipate heat for the nuclear reactor in the atmosphere. In the atmospheric environment, the air intake grille must be used to dissipate heat. When entering space, the heat dissipation capacity will be weakened, which is even more impossible. Deal with the built-up heat.

Once the heat accumulation reaches the limit and the operating temperature is too high, either the spacecraft will fail, or the nuclear reactor will melt and go on strike.

So the nuclear reactor can only choose pulse operation, that is, start for a period of time and then shut down for a period of time, and so on.

This is the nuclear fission pulse system.

When the reactor is shut down, the spacecraft can keep the thermoelectric power generation system running by relying on the waste heat of the reactor, and at the same time let the radiation cooling system work to ensure the safe operation of the spacecraft.

And doing so is also conducive to saving nuclear fuel.

After all, the Tibetan Antelope's fast reactor space is so large, it is impossible to accommodate too much nuclear fuel, so that it can be operated for a while and stopped for a while, which can avoid the waste of nuclear fuel.

Director Niu was still marveling at this power generation system, but Qiu Yongjun suddenly came over and said, "Chief Master, He Weihe Chief Master has something to contact you."

Chen Shen still remembered that this was the person in charge of the domestic lunar exploration project. He nodded, confirmed the current operating parameters of the power generation system, and then left the factory to call him back.

The call was connected quickly, and He Wei breathed a sigh of relief after confirming his identity.

"It can be regarded as contacting you..."

"What's the matter? I was following up on the Tibetan antelope just now." Chen Shen asked, and looked up at the sky by the way, only to realize that it was already night.

"It just happens to have something to do with your Tibetan antelope." There was a sound of drinking water from the other side, and then He Wei continued to say, "You probably didn't read the news just released on the other side, did you?"

"I didn't see it, are they upping the ante in the space race?"

Although I don't know what news He Wei said, but combined with He Wei's identity, he and I specially called to tell him only about the space race.

Chen Shen also guessed deeply, "Is there any latest progress on the SLS rocket? Are they going to make their first flight? Now the opposite side is the most likely to make progress on this project."

It has been four months since the stop of the SLS test in June. During this period of time, there have been several preliminary tests on the opposite side. If the action is quicker, the first flight should not be far away.

He Wei over there said: "You guessed it right. The press conference just happened on the opposite side. The first flight of the SLS will take place after New Year's Day. At that time, they will launch an unmanned spacecraft to the moon. Perform the mission of orbiting the moon and returning, laying the foundation for another manned moon landing later.”

"Their speed is really fast. I originally thought that their first flight would not be possible until April or May next year. Now it seems that the other party has given too much money."

Chen Shen didn't take it too seriously, "How fast is this? After the Tibetan antelope is finished, it can take off at any time. It takes so long to prepare."

Launching a rocket, especially one as big as the SLS, requires a lot of preparatory work.

From production assembly to transportation inspection, to special launchers and transfer vehicles...

This is also where rockets are no match for electric spaceships.

He Wei echoed, "Yes, yes, I think so too. The main reason I called to ask you is if it is possible for our Tibetan antelope to go to the sky with their rockets, and then we can fly with their spaceships." Going to the moon, this is a good story in the world."

He Wei's words were astonishing, and for a while, even Chen Shen didn't know how to complain.

Hitting people doesn't slap people in the face, this Chief Master He is already old, why is he still like this...

What a delight!

Go to heaven with the opposite side...

The old man is quite romantic!

Chen Shen made a quick calculation. The design of the nuclear reactor was completed a while ago, and now the nuclear fuel pellets have been produced, the containment is ready, and the cladding tube has been released. The power generation system seems to be fine now. ...

A long list emerged in Chen Shen's mind, and the projects that had been completed or nearly completed were marked with virtual ticks. As more and more ticks were ticked, Chen Shen also came to a conclusion:

"no problem!"

According to the current progress, the assembly of the nuclear reactor will be completed within one month and the test will be carried out. It will be possible to board the ship and conduct flight tests in December, and it will happen to go to the sky with the opposite SLS on New Year's Day.

Although the progress is a bit rushed, the micro-nuclear reactor and the power generation system are completely based on the system technology. After they are built, as long as they don't cut corners, there will be no problems.

"Okay, then we will complete the preliminary preparations first, and we will wait for your good news at that time. I guess the other party will definitely like our traveling companion very much!" He Wei on the other end of the phone laughed out loud, as if he I was amused by my sudden bad taste.

According to the usual practice, after the news of the first flight of the SLS was sent by the other side, the country also had to respond.

It's just that the domestic response this time is still not the nuclear-powered Tibetan antelope. This big killer is not used for talking.

China announced the space factory plan that was previously solicited from the whole society, and at the same time determined the industry of the first space factory.

That is the pharmaceutical industry.

It is expected that in the next few years, a pharmaceutical factory with at least three production lines will be built in space, and a series of drug manufacturing experiments will be carried out at the same time.

In the special environment in space, the manufacture of some medicines will be more convenient.

Most of the drugs included in the trials are newly developed, and many of them are related to edges and corners...
