  Chapter 283 Space elevator project verification and construction site

   But these are all trivial matters, and Tang Rui won't say anything.

   Anyway, where is Honglian's computing power?

   Not using it is also a waste.

   Besides, the computing power needed to calculate the shape of a car is not even a drop in the bucket.

night.

   Tang Rui received the data uploaded by the employee after eating.

   "Honglian, according to this data, make a robotic arm, remember to install the tactile feedback sensor and the neural signal conversion chip."

   "Master, do you need to load the weapon system?"

"unnecessary."

   "Okay, Master, Guren understands."

   Less than ten seconds.

  Red Lotus just finished the design of the robotic arm, the internal structure is ready-made, just modify the shape according to the data.

  Under the control of Honglian.

  The nano-scale 3D printer began to print the skeleton of the robotic arm.

  The hollow grid skeleton made of new alloy is lighter than the bones of the human body, so even if a little more electric equipment is loaded, the overall calculation is no different from a real arm.

   More than an hour later.

  One robotic arm is finished.

   Tang Rui sent a message to the employee, asking if he wanted metal skin or free skin.

   There is no difference between the two.

   is the appearance is different.

   Metal skin is really like cyberpunk.

  Bionic skin is the same as a real person's arm.

   "Thank you Mr. Tang, we still want bionic skin."

   "Okay, come and get it tomorrow."

  Tang Rui explained to Honglian and went to sleep.

the next day.

  Tang Rui went to Lin Chao and asked him to help with the production license of electric vehicles, and then asked his private team to patent the appearance of the cars designed by the employees.

   Less than three days away.

  Hundreds of employees exchanged points for electric cars, all of which were handed over to them.

  Don’t worry about the card issue.

  Go straight to the special passage and get a green license plate from the vehicle management office.

  The affairs of the company have been dealt with.

  Tang Rui took Li Shuyao to his grandparents' house to prepare for the New Year.

   Compared to last year.

   This year, the health of my grandparents has improved a lot.

  He changed the physiotherapy mattresses for two elderly people last year, which is the same principle as his physiotherapy cabin.

   But his one is used to strengthen the body.

  And what he prepared for the two old men was to repair the body and adjust various systems in the body.

A year has passed.

  The body of the second elder is stronger than before. Not to mention, the common diseases of the elderly are all gone, even the blood pressure has dropped, and there is no need to take antihypertensive drugs.

   "Xiao Rui, when are you going to get married?" Grandma has been thinking about this matter.

  He said before that he was busy, but the old man didn't rush him.

   It’s Chinese New Year now.

   began to urge marriage as usual.

   "Wait two days to go to her house, ask her parents' opinion, and set a date then." Tang Rui didn't shirk.

   After all, we have been together for a year.

   There are no conflicts and contradictions, and they get along relatively harmoniously.

  So he didn't resist getting married or anything.

  When Li Shuyao heard Tang Rui say this, he gave him a special look, which meant that there was a reward.

   It goes without saying what the reward is.

  Tang Rui chose to repair women's clothing this time.

New Year's Eve.

  Tang Rui received a lot of messages of blessings, as well as a lot of New Year's gifts, but he didn't remember the exact number.

  Anyway, there are 17 pages in the list of gift lists compiled by Honglian.

  Most of them are sent from abroad.

   There are a lot of antique jade, jewelry and diamonds, calligraphy, calligraphy and paintings, all of which are enough for him to open a museum.

   Tang Rui didn't feel much after seeing it.

  Because he himself is not interested in these things, but Li Shuyao is very interested in those jewelry.

   Heh, woman.

  Accompanies grandparents to celebrate the new year, and Tang Rui took Li Shuyao to his parents' house for lunch and dinner on the first day of the new year.

   Then there was another meal of marriage urging, saying that when the two parents would meet, they would make a decision.

   On the second day of the Lunar New Year, I came to Li Shuyao's house.

   Tang Rui took the initiative to bring up the matter of marriage, which made Li Shuyao's parents very happy, and then they started talking about this topic.

   "Brother-in-law, if you hold a wedding, how many tables do you want?" The uncle asked curiously.

  Tang Rui was stunned when he heard this question.

  How many tables?

  If it’s just relatives and friends on both sides, that’s okay, but the problem is that he can’t count how many people on his side.

  Even if he doesn't invite people to come, there will definitely be many people rushing over. When you get married, it's not easy for you to drive people away.

   At that time, it is hard to say whether one hundred tables will be enough to sit.

   "This is indeed a problem, I have to think about it." Tang Rui said seriously.

   "Actually, there is no need to make a fuss, just invite relatives and friends to have a meal together." Li Shuyao's father said.

   "That won't work, just get married once, and there should be some scenes." Tang Rui shook his head. On this point, he still has his own ideas.

   "Brother-in-law, if there are many people, we can take down the resort, the venue over there is enough."

   "Holiday resort? No, it's not high enough." Tang Rui shook his head.

   "Wedding City, how about a Chinese wedding?"

   "Ten miles of red makeup, Fengguanxiapei?"

  Tang Rui's eyes lit up when he heard about the Chinese wedding, and he turned to look at Li Shuyao, wondering what she was thinking.

  Li Shuyao was also moved when she heard the eight words Tang Rui said.

  Which woman would not like Feng Guanxiapei.

  The wedding dress is in front of Feng Guanxiapei, so it's not up to the mark at all.

okay.

knew.

   Tang Rui understood when he saw Li Shuyao's expression.

   "That's a Chinese wedding, but the wedding city won't work. I'll figure out a way for the venue."

   "Brother-in-law, you don't want to go to Hengdian, just build a palace for the wedding."

   Tang Rui shook his head, Hengdian was not in his consideration.

  According to his personality, if he wants to do it, he will do it big.

  The palaces in Hengdian are enough, but not high enough.

   But there is no hurry.

   If it really doesn’t work, just build a piece of land and build an ancient palace complex for weddings.

   It's a high-profile thing to do.

   But in his current situation, as long as it is not a matter of principle, then everything else is not a problem.

   In a blink of an eye, it will be the seventh day of the Lunar New Year.

   After the new year, everyone starts working, and Tang Rui will also start busy.

   But he hasn't had time to busy himself with his own affairs.

   was called to a meeting.

  The content of this meeting is to discuss several major projects this year, namely the space station, earth orbit defense and space elevator.

  These three plans complement each other.

   It can even be said that these three plans can be launched at the same time, so the content of the meeting discussion is the actual construction difficulty and design indicators.

  Meetings are important.

  So the questions raised by everyone are also targeted.

   Among them is the cable material problem of the space elevator.

   Coincidentally.

   Tang Rui can directly answer this question.

   "Everyone knows about the cable, that is, carbon nanotubes. According to calculations, it can be concluded that as long as the tensile strength of the cable made of carbon nanotubes reaches 70GPa, then it has reached the manufacturing standard of a space elevator.

  Currently, the carbon nanotubes produced by Crimson Company have a tensile strength of 350GPa, which is far beyond the space elevator's strong demand for materials.

  At the same time, the 80 cables with a length of 52,000 kilometers required for the entire space elevator can be manufactured within half a year. "

   Tang Rui opened his mouth and directly solved the biggest difficulty of the space elevator. Everyone knows the strength of carbon nanotubes before, but the problem is that it is impossible to manufacture such long carbon nanotubes.

   But for Tang Rui, this is not a problem at all.

   "Excuse me, Academician Tang, how did you calculate the length of 52,000 kilometers? Why did you choose such a length?"

   An academician immediately asked after listening.

   It's not aimed at Tang Rui, but just asking the key questions. After all, there is an argument for this length.

   "According to my design of the space elevator, it can be divided into three stages. The first stage is the section from the base on the earth's surface to the airport space station. The length of this section is 36,000 kilometers.

  The second stage is the airport space station, where a huge ring is to be built, using centrifugal force to generate pseudo-weight, so that the staff can stay in the airport for a long time.

  The third stage is from the airport space station to the trim gravity armed satellite platform at the end of the cable. The length of this section is 16,000 kilometers.

  The reason for the length of 52,000 kilometers is that the first consideration is the height of the geosynchronous geostationary orbit, and the second consideration is the weight of the armed satellite platform.

  If there is no armed satellite platform, the length of the cable needs to reach 130,000 kilometers, which is definitely not possible.

  But if the armed satellite platform is too heavy, although the length of the cable at the end can be shortened, that will lead to the stability of the entire platform.

  So after countless simulation calculations, the length of 52,000 kilometers is the optimal solution for the length of the space elevator cable. "

  Tang Rui did not hesitate to tell the specific situation directly.

   This is the optimal result obtained after many calculations by Honglian. If it is longer or shorter, it will affect the stability of the entire system.

   "Academician Tang, according to your statement, the airport space station uses centrifugal force to create gravity, but then the mass of the entire space station will become terrible.

  Once the space station tilts, the cables of the space elevator will break. How to solve this problem? "

  Another academician raised a question. After all, this is indeed a fatal problem. Unless you can guarantee that the space station will never tilt at all, otherwise, even carbon nanotubes cannot withstand the power of the space station.

  “About this point, it is actually easy to solve, that is, to separate the space station from the main track of the space elevator, and not to make hard connections, but to use only soft connections.

  Although doing so will cause great problems in attitude adjustment and orbit control, as long as a soft connection like an electromagnetic bearing is used, this problem can be solved.

  At present, this technology has been overcome by me, so the orbit, attitude and tilt angle of the airport space station are no longer a problem. "

  After everyone listened, they all nodded.

  If this is the case, then the technical difficulties of the space elevator project have basically been overcome.

   As for engineering difficulties, it is at most a matter of trouble.

   "Academician Tang, do you have any recommendations for the manufacturing location of the space elevator?" the person from the National Academy of Sciences asked.

  Tang Rui said four words: "Mogadishu."
