I am reborn as Say, but the animation three-body

Chapter 57 Changan and cargo spacecraft

While ETO was still lamenting that Say was too cautious, Say in question was attending the completion ceremony of the first-generation radiation-driven spacecraft at the PDC Research Center.

Now, 14 years have passed since she recruited Zhang Beihai and proposed the development of a refrigerant-free engine. PIA and various governments finally developed and built the first radiation-driven spacecraft.

It is a major breakthrough for mankind. The birth of the radiation-driven spacecraft represents the first step that human civilization has finally taken towards the boundless space.

This greatly boosted people's morale. Although there is still a huge gap between it and the Trisolaran civilization, at least this is a start.

At the same time, now that such great results have been achieved, the old aerospace industry can no longer find any reason to continue to cause trouble. In other words, if the old aerospace industry is still making trouble now, it is definitely ETO, and they should be arrested and judged immediately.

As the Wallfacer and Chairman of the PDC, Sai naturally came.

"Chairman Say, your suggestion is indeed wise. The refrigerant-free engine is indeed the future of mankind." After seeing Say, several veteran aerospace experts who had been having the most fun came over and apologized.

In such a defensive world, many people do things without thinking, just like the Trisolarans, they just say whatever they want.

For example, these veterans of the aerospace industry have repeatedly cursed in public, saying that people who want to study fluid-free engines are pigs, and that Sai and Zhang Beihai's Chang'an Deep Black Project is a waste plan.

"It's okay, we are all for human civilization." Sai said casually. Since the other party did not imitate the African aerospace engineer to play assassination, she was too lazy to argue with these people.

Cheng Xin then continued: "So based on the Chang'an's top speed, it only takes less than half an hour to cover this distance."

"Don't you want to? Exploiting the resources of other planets will be of great help to mankind in fighting against the Trisolarans. I'm just at the forefront." Sai asked in return.

"If the transportation is very simple, you can just modify the Chang'an appropriately. But let me know first, do you have any requirements on the transportation time and location? If you want to develop Pluto, it will be more difficult."

As for weapons, hydrogen bombs and electromagnetic kinetic energy cannons are still the main ones at present. However, due to the great interest of the nine major council members in weapons, it is possible that its derivative version will be equipped with laser weapons.

Cheng Xin didn't care much about Sai's support for refrigerant-free engines at first, but after learning the sinister details, she felt a little scared.

"No, I am only considering low-Earth orbit and the moon now. I won't use other planets for the time being. Even Mars is not considered," Sai said.

"Awesome!" Sai couldn't help but sigh. Compared with traditional spaceships, this is a qualitative improvement. Even the carrying capacity of the aircraft is far less than that of the Chang'an.

"Chairman Say, to be honest, I personally think that 7 hours is not a long time. It takes almost 5 hours to fly from BJ to Manila."

"The current stage is transportation. My next plan requires a cross-planet cargo spacecraft. The Chang'an looks like a good template."

"I think it's around 380,000 kilometers."

"Okay, thank you." Sai said.

"You want to develop space?" Cheng Xin asked curiously.

Sai was not surprised to hear this, because the ladder plan was forcibly canceled by her, so Cheng Xin did not go into hibernation, but went to study the refrigerant-free engine.

"By the way, Ms. Cheng Xin, can this kind of spaceship be converted for civilian use?" Sai suddenly asked.

The name of this spaceship is Chang'an. It does not belong to the three major fleets or any country, but is an experimental spacecraft of the PDC scientific research department.

"What type of civilian use do you want? Mining and exploration, scientific research and exploration, space construction or cargo missions?"

"In this way, the load capacity of the spacecraft can be greatly increased, and the cost is also reduced a lot. At the same time, time will not be delayed, because even if it flies from the earth to the moon at the first cosmic speed, it only takes less than 7 hours."

After hearing this, Cheng Xin brought the tablet and began to report the basic parameters and information of the spacecraft to Sai.

"I have to thank you for her being able to be born." Cheng Xin smiled and said: "Your attitude towards insisting on no working substance is correct. It was really dangerous at that time. Several people in key positions were old aerospace experts from the working substance faction.

.”

Internally, it is equipped with the latest generation of deuterium-helium 3 fusion reactor, which can reach 20 times the speed of the third universe when propelled at full power.

"Of course, the distance between the earth and the moon is too short, not even enough for the Chang'an to accelerate, so if we set off from the space station, it will take about 2-3 hours to reach the moon."

"By the way, Chairman Say, this is Ms. Cheng Xin. She is the current chief engineer of the radiation-driven spacecraft project." One of the old aerospace experts suddenly introduced.

The Chang'an looks like a long oval stick, which is completely different from a traditional spaceship. Its tonnage is 3,000 tons on earth, which is equivalent to the weight of a large frigate.

"If you hadn't helped us deal with the old aerospace industry and persisted in insisting on working fluid-free engines against all opinions, it is very likely that the research focus of human civilization would have been on working fluid fusion engines."

After all, she didn't know about the incident in the original book about Beihai's gunshot attack on Lao Aerospace. In Cheng Xin's eyes, the work substance faction almost won.

"Humanity is indeed developing rapidly." Say said with emotion: "Just more than 20 years ago, it was extremely difficult to land on the moon. Now it theoretically takes less than an hour to go to the moon from the earth."

"That's too simple." Cheng Xin analyzed: "Judging from the current speed of Chang'an, it is even too fast. We only need to reduce the speed to one-tenth of the current speed. I believe you should know that the moon

The distance from the earth."

"Yes, unlike other planets, the distance from the moon to the earth is basically constant because they form the earth-moon system."

"Theory and reality are always different. Since your requirement is transportation rather than combat, the ultimate speed of the cargo spacecraft can be reduced to twice the speed of the third universe, which is one-tenth of the Chang'an."

At the same time, because of Say's Fourth Agricultural Revolution plan, it also has partial ecological recycling capabilities and can sail in space for several years without replenishing supplies.

"Hello, Chairman Sai, do you want me to introduce you to this unmanned spaceship?" Cheng Xin said, even though she is the chief engineer of this project, she is also Sai's subordinate.

"This time is indeed no problem, but if the speed is reduced to twice the speed of the third universe, how much load capacity can this cargo spacecraft have, and how much lower its cost can be than the Chang'an spacecraft." Sai asked.

"I need to calculate this with a professional."

"Then calculate it as soon as possible and give me a report." Sai ordered.
