The light-pressure engine design project was approved, and the science and technology department, including Mr. Xu, Deng Huaizhen, and Chen Yongshuai, were very surprised.

At the same time, they all felt that the project was a bit too sci-fi.

Chen Yongshuai is the head of the Annihilation Science and Technology Division, and after the light-pressure engine design project is approved, he will be responsible for deploying researchers, because of the lack of understanding of research, he decided to make a special trip to the West Sea.

When he was on the road, Chen Yongshuai recalled Mr. Xu's advice, "After you arrive in Xihai, take a closer look at their research, I always feel too advanced." ”

"On the basis of the current foundation, it is a bit of a waste to do this kind of research that is too advanced......"

"You take a look at it more, and persuade Wang Hao more."

"Take a look at it and look for problems, I always feel that this research is unreliable." Mr. Xu was very serious, and Deng Huaizhen agreed with him.

Light-pressure engine?

That's the technology that can only be used for space travel.

Even with the annihilation particle technology as the foundation, to meet the standards for manufacturing light-pressure engines, I don't know how many technical difficulties there are that cannot be overcome.

Chen Yongshuai also felt that what Mr. Xu said was reasonable, but he felt that all he could do was to understand, and then persuade Wang Hao.

That's all.

The project for the light-pressure engine is self-funded.

Wang Hao's research group spent their own money to conduct their own research, and they could continue their research without the approval of the science and technology department, but there was no support for personnel deployment.

Chen Yongshuai thought and shook his head.

Soon.

He went to Seohai University.

Chen Yongshuai's arrival was very low-key, he only brought his assistant and two other staff members, and did not inform Xihai University, so he came directly to the Mason Number Laboratory.

Wang Hao knew that Chen Yongshuai would come, so he still asked people to greet him at the door.

After Chen Yongshuai entered the laboratory, he was taken to the temporary workshop of the research group by Paul Phil-Jones and Ding Zhiqiang.

The workshop is a large office on the edge of the second floor, with armed guards guarding the doorway to prevent anyone other than members of the research team from entering.

After Chen Yongshuai entered the workshop, he saw that there were a lot of printed drawings on the big table in the middle, and some were hand-animated, he picked up one and looked at it carefully, and found that he couldn't understand the content at all, and then raised his head to notice that there was a large drawing on the wall opposite, and on the drawing was a large round ball, with a standard diameter of 120 meters.

"What is this?"

Chen Yongshuai just asked Paul Phil Jones with a big round ball.

"Optical engine!"

Paul Phil-Jones rightly said, "That's what the light-pressure engine is. This diagram shows the main frame structure, and the sphere that occupies the largest volume is the concave mirror structure. ”

"120 meters in diameter?" Chen Yongshuai's expression was a little exaggerated, "It looks like a large stadium......"

Paul Phil-Jones said, "120 meters is already the smallest design. In fact, we initially thought that concave reflective structures over two hundred meters should be built. ”

"But then it was discussed that we should make a small one first."

"The larger the concave reflection structure, the higher the efficiency of the light source, 120 meters in diameter, the effect will be much worse, but for now it is enough......"

He shook his head helplessly, "Energy efficiency is not a problem. Now this design can theoretically propel more than 10,000 tons of spacecraft into space. ”

"But it's still too small."

With a sigh, Paul Phil-Jones found a drawing from the large table, unfolded with the tip of the large ball.

The nose end is a frame above a large rocket.

"This is the space carrier we designed, which can be understood as a spaceship. In terms of appearance, we haven't decided yet. ”

The topic suddenly jumped to the spaceship, and Chen Yongshuai felt a little unable to adapt.

From the moment he entered the door and was entertained by Paul Phil-Jones, the other party's personality and tone of voice made him feel very awkward, and when he heard about the spaceship, he felt like he was dealing with a madman.

He suddenly thought of Teacher Xu's advice.

That's right!

Find out the problem!

"Let them retreat? Or discourage them and let them know that any light-pressure engines and spaceships are just science fiction imaginations......"

"Reality is impossible to make!"

Chen Yongshuai made a decision, looked at the drawings carefully, immediately found the problem, and asked, "The design of your spacecraft looks pretty good, but isn't there a design for the lateral annihilation force field?" ”

The top of the spaceship is similar to that of a large rocket, except that it is much larger, with a cylinder diameter of more than 70 meters.

The design of the cylinder certainly does not include transverse annihilation force field technology.

In the case of transverse annihilation force field technology, the final design will definitely have a 'disc', otherwise the field force will not work at all.

Paul Phil-Jones shook his head, "So I said, it's not settled yet." ”

"Wang Hao and I have discussed several times whether the ship should use the lateral annihilation force field technology, but in the end there is no result, because the spacecraft is traveling in space, and it does not need the lateral annihilation force field technology, and there is no need to reduce the weight of the spacecraft."

"There are too many limitations to lateral annihilation force field technology, for example, to use low-temperature superconducting materials, then the spacecraft must carry a lot of coolant."

"That's a big limitation."

"The biggest role of lateral annihilation force field technology is still in ground activation, that is, taking off from the surface of the planet to get rid of gravity."

"If the engine is powerful, you don't need this technology to lose weight......"

Chen Yongshuai listened stunned, and immediately asked, "Don't you need to lose weight when you sail in space?" The light-pressure engine can provide enough power to bring the spacecraft close to the speed of light, so acceleration is a problem, and after weight reduction, acceleration will become faster......"

"Theoretically, that's so."

Paul Phil-Jones agreed with Chen's statement and then continued, "But actually, there is one issue that must be considered, the human body's ability to bear it. ”

"Even if the engine is sufficiently powerful, the design must be designed with the human body in mind."

"If the spacecraft is built, there will definitely be some scientists on it, not all astronauts with special training."

His voice was flat.

Chen Yongshuai looked Paul Phil-Jones up and down, always feeling that the other party was talking about himself, and Paul Phil-Jones fully met the criteria of 'a scientist who wins physically and weakly'.

Paul Phil-Jones continued, "So it's best not to exceed 2G under pressure, and not more than 3G at most. ”

"That's the limit!"

"We can make a lot of power, but we have to find ways to limit performance." That's why I initially said that a 120-meter diameter concave mirror would be sufficient. ”

The endurance of the human body is a big limitation in the aerospace field.

The bearing capacity of the human body to acceleration is limited, generally speaking, the highest bearing capacity of the human body is about 10G, which is the early astronaut.

At that time, the aerospace equipment was very backward, but the acceleration of the rocket was very large, and within 30 seconds after the rocket took off, the acceleration load would reach 10G (close to 98 m/s squared).

Now the rocket technology has been relatively perfect, when the rocket lifts off, the average carrying capacity of astronauts is about 3G.

That's already high.

Paul Phil-Jones went on to lament, "When you really study spacecraft, you realize that there are so many technical limitations. ”

"Originally, I thought that relying on a light-pressure engine would allow the spacecraft to accelerate to nearly the speed of light in a short period of time......"

"If it is only an acceleration of 30 meters, it will take nearly a million seconds to reach the speed of light, and it will take more than ten days ......."

His voice was full of regret.

Chen Yongshuai didn't care about Paul Phil-Jones's mood, he looked at the content on the drawing very seriously, and found that his question was perfectly explained.

"Doesn't seem to be a problem......

He thought.

Then he turned his head and continued to look at the light-pressure engine, and also asked about some parts of the frame design one by one.

Paul Phil-Jones was very patient in answering questions.

This is mainly because he knows that Chen Yongshuai is related to the issue of 'design team personnel allocation'.

The research group are all theoretical physicists, and they have no problem designing the engine frame, but when it comes to the details of technology, materials, circuits, etc., it definitely requires professionals in various fields.

For the sake of the light-pressure engine research, Paul Phil-Jones thought it was worth 'sacrificing' himself to explain the technical problems to the visiting official.

……

Chen Yongshuai carefully understood the design of the light-pressure engine, and in the process of chatting with Paul Phil-Jones, he expressed every question in his heart.

Subsequently, he met Wang Hao.

Wang Hao is very confident in the research of light pressure engines, and he directly talked about the formation of the design team, "We need talents in various fields, especially materials and aerospace." ”

"Preferably some young cutting-edge talent from the space agency. Materials are also very important, preferably in the R&D team in the field of aerospace materials. ”

"Teacher Chen, is it okay?"

In the face of Wang Hao's direct inquiry, what else could Chen Yongshuai say?

He could only nod in the affirmative.

Afternoon.

Chen Yongshuai hurried back, and Paul Phil-Jones and Ding Zhiqiang sent him to the gate of Xihai University, which was also a rare show of enthusiasm.

Paul Phil-Jones has few friends, and he and Chen Yongshuai had a good chat, so he felt that he could play a role in that friendship, and even expressed his imagination for the future.

"I've already discussed it with Wang Hao."

"When the ship is built, I will be the deputy captain, and when the time comes, you can call me the deputy captain Paul Phil-Jones!"

"And my ......"

Ding Zhiqiang weakly fought for his own rights and interests, "Ding Zhiqiang, deputy captain!" ”

Chen Yongshuai said funny, "What about me?" ”

"You?"

"Theoretically, there can't be more than three co-captains." Paul Phil-Jones thought for a moment, "Either you will be the assistant to the co-captain, or...... Boarding as a friend? ”

“……”

Chen Yongshuai felt speechless.

As a senior official in the tech department, he was surrounded everywhere he went, to Paul Phil-Jones......

Aides?

With a strange mood, Chen Yongshuai took the plane back to the scientific research department, and on the way, he thought about the design of the light-pressure engine and the spacecraft.

He found that he couldn't find anything wrong, and he was very much looking forward to the engine and the construction of the ship.

"No problem."

"There is already annihilation particle technology, and there are many breakthroughs in materials, and the whole design is theoretically feasible."

"This research may be successful!"

Chen Yongshuai suddenly thought of his position, the head of the Annihilation Science and Technology Division, "Perhaps, when the spacecraft is manufactured, I can also go up and feel it?" ”

"That Paul, who said he was going to be the second captain......"

"Although the project belongs to the Annihilation Force Field Experimental Group, I am in charge of the Annihilation Technology Division, and I can be regarded as a direct superior, and I can also serve as a ...... Vice Captain? ”

The more he thought about it, the more excited he became, and he found it very interesting.

In the afternoon of the next day, Chen Yongshuai went to the science and technology department and went to Mr. Xu's office.

Teacher Xu immediately asked, "How's that?" Have you met Wang Hao? What do they say about their project? ”

"I think ......"

Chen Yongshuai hesitated for a moment and continued, "I think it's feasible! Their design is very thorough, and I couldn't find anything wrong. ”

"If you can build a light-pressure engine, you can build a spaceship based on it, and it's a spaceship that can reach the speed of light."

"If we build this kind of spaceship, space ......"

"It's all ours!"

Chen Yongshuai said very seriously.

Teacher Xu listened with surprise, he turned his head to look at Deng Huaizhen, and he didn't know what his mood was.

Chen Yongshuai......

This guy went on a trip to the West Sea and was convinced?

……

After the light-pressure engine project was confirmed, Chen Yongshuai immediately began to deploy personnel.

According to Wang Hao's request, he found Mr. Xu, contacted the Space Bureau to cooperate with several top aerospace materials experts, and found the Institute of Aeronautical Materials for explanation.

The space agency is also preparing to start a new program.

When Chen Jiahe learned that the experts of the aerospace materials group had been deployed to participate in a confidential research and development project, he immediately approached the science and technology department, one was to learn about the so-called 'confidential project', and the other was to hope that there would be a few fewer places for the material experts of the space bureau to stay.

He's confident.

No matter what kind of classified project, can the level be higher than the new plan of the space agency?

They're going to make a 'flying saucer'!

Chen Jiahe first found Mr. Xu, and Mr. Xu pushed the problem to the Department of Annihilation Science and Technology, but he still found Chen Yongshuai and said very seriously, "Our new plan is to develop an aerospace flying saucer, and conduct aerospace exploration based on an air-ship flying saucer." ”

"It's going to be a far better than the Space Shuttle!"

"We have entered the demonstration stage, and there is also a great need for experts in aerospace materials......"

Chen Jiahe said very confidently.

Chen Yongshuai showed no interest, and after listening carefully, he wondered, "The space flying saucer based on the flying saucer of the air ship is not just a Hall thruster installed on the flying saucer of the air ship?" ”

In a word, the style of the space saucer has been lowered by N notches

Chen Jiahe said embarrassedly, "It can be understood like this." ”

Chen Yongshuai said, "It is more important to have a new project, and the reason why we dispatched aerospace materials experts is because Academician Wang Hao wants to develop a new aerospace engine." ”

"You can understand this situation, right?"

Chen Jiahe was stunned when he heard this, and immediately asked, "What kind of technology is Academician Wang studying?" ”

"Light-pressure engine."

Chen Yongshuai said very frankly, "If you think about it, your research is to install a few Hall thrusters on the flying saucer of the empty ship, and Academician Wang's research is a light-pressure engine. ”

"Which high-end?"

“……”

Does this need to be asked?

Chen Jiahe felt his brain buzzing, and kept muttering the words 'light pressure engine' in his mouth.

Chen Yongshuai continued, "We are not directly transferred from the space agency, we are all voluntary. If you want to participate in Academician Wang Hao's project, you can go over, and it doesn't matter if you don't want to participate, it's all voluntary and self-applied. ”

"You can also tell your material experts not to go."

"It's okay."

Chen Jiahe was speechless for a moment.

Instead, he hopes to convince the materials experts not to participate in Wang's project.

But how is that possible?

When he heard that he was participating in the confidential project led by Academician Wang Hao, almost all those who were eligible to apply had applied, and the enthusiasm made him feel that the space agency could be disbanded......

That's why he's here in the tech department!
