The light pressure engine design project was approved, and everyone in the science and technology department, including Teacher 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 Technology Department. After the light pressure engine design project is approved, he will be responsible for allocating researchers. Because of his lack of understanding of the research, he decided to make a special trip to the West China Sea.
On the way, Chen Yongshuai recalled Teacher Xu's advice, "After you arrive at Xihai, take a closer look at their research. I always feel that it is too advanced."
"Based on the current foundation, it would be a bit wasteful to do such advanced research..."
"Look more and give Wang Hao more advice."
"Learn more about it and look for problems. I always feel that this research is unreliable." Teacher Xu said very seriously, and Deng Huaizhen also agreed with his point of view.
Light pressure engine?
That is a technology that can only be used to realize space navigation.
Even with annihilation particle technology as the basis, there are still many technical difficulties that cannot be overcome in order to meet the standards for manufacturing a light pressure engine.
Chen Yongshuai also felt that what Teacher Xu said was reasonable, but he felt that all he could do was to understand it, and the most he could do was to persuade Wang Hao.
That's all.
The photopressure engine project is self-funded.
Wang Hao's research team spends their own money to conduct research. Even if the science and technology department does not approve it, they can continue their research, but they do not have the support of staff deployment.
Chen Yongshuai thought and shook his head.
soon.
He went to Xihai University.
Chen Yongshuai's arrival was very low-key. He only brought his assistant and two other staff members, and went directly to the Mason Number Laboratory without notifying Xihai University.
Wang Hao knew that Chen Yongshuai would come, so he still asked someone to greet him at the door.
After Chen Yongshuai entered the laboratory, he was taken to the research team's temporary workshop by Paul Phil-Jones and Ding Zhiqiang.
The workshop is a large office on the side of the second floor, and there are armed guards guarding the door to prevent people other than members of the research team from entering.
After Chen Yongshuai entered the workshop, he saw a lot of printed drawings on the big table in the middle, and some were drawn by hand. He picked up one and looked at it carefully, and found that he could not understand the content at all. Then
Only when I raised my head did I notice that there was an oversized drawing on the wall opposite. The drawing showed a large sphere with a standard diameter of one hundred and twenty meters.
"What's this?"
Chen Yongshuai just asked Paul Phil Jones about the big ball.
"Light pressure engine!"
Paul Phil-Jones said of course, "The light pressure engine is like this. This picture is the main frame structure, and the sphere occupying the largest volume is the concave mirror structure."
"120 meters in diameter?" Chen Yongshuai's expression was a bit exaggerated, "It looks like a large stadium..."
Paul Phil-Jones said, "120 meters is already the minimum design. In fact, we originally thought we should build a concave reflective structure of more than 200 meters."
"But later we discussed and thought that we should first make a small one to see."
"The larger the concave reflective structure is, the higher the light source utilization efficiency will be. With a diameter of 120 meters, the effect will be much worse, but it is enough for now..."
He shook his head helplessly as he spoke, "Energy utilization efficiency is not a problem. Now this design can theoretically propel a spacecraft of more than 10,000 tons into the sky."
"But it's still too small."
Paul Phil-Jones sighed and found a drawing from the big table. After unfolding it, it showed the front end of a large round ball.
The front end is a frame above a large rocket.
"This is the aerospace carrier we designed, which can be understood as a spaceship. In terms of appearance, we have not determined it yet."
The topic suddenly jumped to the spaceship, and Chen Yongshuai felt a little unable to adapt.
From the moment he walked in and was greeted by Paul Phil Jones, his character and tone of voice made him feel very awkward. When he heard about spaceships, he felt like he was dealing with a madman.
He suddenly thought of Teacher Xu's advice.
yes!
Find the problem!
"Tell them to give up before the difficulties? Or dampen their enthusiasm and let them know that light pressure engines and spaceships are just science fiction imagination..."
"Reality is impossible to create!"
Chen Yongshuai made a decision, looked at the drawings carefully, and immediately found the problem and asked, "The design drawing of your spaceship looks pretty good, but is there no design for a horizontal annihilation force field?"
The top of the spacecraft is similar to a large rocket, but the design is much larger, with a cylinder diameter of more than 70 meters.
The design of the cylinder certainly does not include transverse annihilation field technology.
If it is horizontal 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 and said, "So I said, it hasn't been determined yet."
"Wang Hao and I discussed several times whether the ship should use transverse annihilation field technology, but in the end there was no result, because the ship does not need transverse annihilation field technology to sail in the universe, and there is no need to specifically reduce the weight of the ship.
"
"The transverse annihilation force field technology is subject to too many limitations. For example, if low-temperature superconducting materials are to be used, a large amount of coolant must be carried in the spacecraft."
"That's a big limitation."
"The biggest role of the lateral annihilation field technology is in ground activation, that is, taking off from the surface of the planet to get rid of gravity."
"If the engine power is sufficient, there is no need for this technology to reduce weight..."
Chen Yongshuai listened blankly and immediately asked, "Don't you need to lose weight to sail in the universe? The light pressure engine can provide enough power to bring the spacecraft close to the speed of light, so acceleration is a problem. After losing weight, the acceleration will be
It will get faster..."
"That's the theory."
Paul Phil-Jones agreed with Chen Yongshuai's statement and then continued, "But in fact, one issue must be considered, the endurance capacity of the human body."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Even if the engine has sufficient power, the design must consider the endurance of the human body."
"If the spacecraft is built, there will definitely be some weak scientists on board, not all specially trained astronauts."
His voice was very calm.
Chen Yongshuai looked Paul Phil-Jones up and down, always feeling that the other person was talking about himself. Paul Phil-Jones fully met the standard of 'scientist whose body wins over the weak'.
Paul Phil-Jones continued, "So the acceleration pressure should not exceed 2G, and the maximum pressure should not exceed 3G."
"This is the limit!"
He lamented, "We can produce sufficient power, but we still have to find ways to limit performance. That's why I initially said that a 120-meter-diameter concave reflector is enough."
The endurance of the human body is a big limitation in the aerospace field.
The human body's bearing capacity for acceleration is limited. Generally speaking, the highest bearing capacity the human body can bear is around 10G, which appeared in the early astronauts.
The aerospace equipment at that time was very backward, but the acceleration of the rocket was very high. Within thirty seconds after the rocket took off, the acceleration load would reach 10G (nearly 98 meters/second square).
Today's rocket technology has been relatively perfect. When the rocket takes off, the average carrying capacity of astronauts is about 3G.
This is already very high.
Paul Phil-Jones continued to lament, "When we really studied the spacecraft, we discovered that there are so many technical limitations."
"Initially, I thought about relying on the light pressure engine to accelerate the spacecraft to close to the speed of light in a short time..."
"If the acceleration is only 30 meters, it will take nearly one million seconds or more than ten days to reach the speed of light..."
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 carefully and found that his question was explained perfectly.
"There seems to be no problem..."
he thought.
Then he turned around and continued to look at the light pressure engine, and also asked about the frame design issues of some parts one by one.
Paul Phil-Jones answered very patiently.
This is mainly because he knows that Chen Yongshuai is related to the issue of "deployment of design team personnel".
