Chapter 57 Chang'an and the Cargo Spaceship
While ETO was still lamenting that Say was too cautious, Say, who was being discussed, was participating in the completion ceremony of the first-generation radiation-driven spacecraft at the PDC Research Center.

It has been 14 years since she recruited Zhang Beihai to come in and proposed to develop a propellant-free engine. PIA and the governments of various countries finally developed and manufactured the first radiation-driven spacecraft.

It is a major breakthrough for human beings. The birth of radiation-driven spacecraft represents the first step of human civilization to the boundless space.

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

At the same time, with such great achievements now, the old aerospace people can no longer find a reason to continue to make troubles, or the old aerospace who are still making troubles now, it is definitely ETO, and they can be directly arrested at first instance.

As a Wallfacer and the chairman of the PDC, Say naturally came.

"Chairman Say, your suggestion is really wise. No propellant engine is indeed the future of mankind." After seeing Say, several of the happiest old astronauts came over and apologized.

In such a debating world, many people do things without using their brains, just like the Trisolarans, they can say whatever they want.

For example, these veterans of aerospace, they have repeatedly yelled in public, saying that people who want to study non-propellant engines are pigs, and they also said that the Chang'an Deep Black Project of Say and Zhang Beihai is a waste project.

"It's okay, we are all for human civilization." Sai said casually, since the other party didn't imitate the African-American aerospace engineer in assassination, she didn't bother to care about these people.

"By the way, Chairman Say, this is Ms. Cheng Xin, she is the current chief engineer of the radiation-driven spaceship project." One of the old astronauts suddenly introduced.

Sayy was not surprised to hear this, because she forcibly canceled the ladder project, so Cheng Xin did not go to hibernation, but went to study the non-propellant engine.

"Hi, Chairman Say, do you need me to introduce this unmanned spaceship to you?" Cheng Xin said. Even if she is the chief engineer of this project, she can be regarded as Say's subordinate.

"Okay, thank you." Said.

After hearing this, Cheng Xin took the tablet and began to report the basic parameters and information of the spaceship to Say.

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

Chang'an looks like a long oval stick, completely different from traditional spaceships. Its tonnage is 3000 tons on Earth, which is equivalent to the weight of a large frigate.

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

At the same time, because of Say's fourth agricultural revolution plan, it also has a partial ecological cycle capability, and can sail in space for several years without replenishing supplies.

As for weapons, hydrogen bombs and electromagnetic kinetic energy guns are still the main ones at present, but because the nine council members are very interested in weapons, their derivative versions may be equipped with laser weapons.

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

"She was born thanks to you." Cheng Xin smiled and said, "Your attitude towards Wuzhi's insistence was correct. It was really dangerous at that time, and the few people who started in key positions were all veterans of the Wuzhi school. .”

"If you hadn't helped us dispose of the old spaceflight and insisted on the non-propellant engine against all opinions, it is very likely that the research focus of human civilization will be on the propellant fusion engine."

At first, Cheng Xin didn't care much about Say's support for the refrigerant-free engine, but after learning about the dangerous details, she felt a bit of fear.

After all, she didn't know about Zhang Beihai shooting Lao Hanghang in the original book, and in Cheng Xin's eyes, the Gongzhi faction almost won.

"By the way, Ms. Cheng Xin, can this spaceship be used for civilian use?" Say asked suddenly.

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

"The current stage is transportation. My next plan requires a transplanetary cargo spacecraft. Chang'an seems to be a good template."

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

"Don't you want to? Mining the resources of other planets will be of great help to human beings against Trisolarans. I'm just at the forefront." Say asked.

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

"No, I'm only considering the low-Earth orbit and the moon right now, and I don't use other planets for the time being, even Mars is out of consideration." Said.

"That's too simple." Cheng Xin analyzed: "Looking at the current speed of Chang'an, it's even too fast. You just 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."

"I remember it was around 38 kilometers."

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

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

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

"The development of human beings is indeed rapid." Sai said with emotion: "Just over 20 years ago, it was extremely difficult to land on the moon. Now it takes no more than an hour to go from the earth to the moon theoretically."

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

"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, the time will not be delayed, because it only takes less than 7 hours to fly from the earth to the moon at the first cosmic speed."

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

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

"I need to calculate this with a professional."

"Then do the calculation as soon as possible, and then give me a report." Sai ordered.
