Chapter 245 Mechanical Arm

On September 16, Lin Ju received a gift in Qiongzhou, which was handed over by the Space Administration.

A palm-sized alloy J-20 plane model, the shape should be laser cut, with traces of high-temperature ablation and oxidation on the edge, the overall silver-white, looks a little dirty like dust, but in fact it cannot be wiped off, it is the color of the material itself.

The four numbers 2201 were also laser-printed on the metal surface, which is obviously the number of the verification machine.

The person who brought the gift said, "This is the J-20B model given to you by Chief Designer Yang Wei. It was cut from the fuselage beam."

After some explanation, Lin Ju realized that the XW-9 engine interceptor version of the J-20 had already made its maiden flight. He was immediately confused: "Why was the beam of the test aircraft cut? What's wrong with the plane?"

The person smiled bitterly: "Although the fuselage skin of the J-20B has passed the test considering the deformation under high temperature, it has forgotten that the internal part of the fuselage has also been conducted to high temperature. After 10 minutes of 3.43 Mach ultra-high-speed flight, the beam almost extended 70cm and broke the skin.

Although the plane landed safely, the beam had irreversible damage and could only be scrapped. The fuselage needs to be redesigned, but the XW-9 performed very well and there is no problem."

"..."

"Say hello to him for me. It will take some time for me to return to Shuchuan. I accepted the gift and I like it very much."

Lin Ju accepted the gift and calculated the time. Lao Ma had already boarded the plane.

Ma Yilong's first stop in China is of course Shanghai. He also came last year, but he only stayed for a few dozen hours and left in a hurry without watching the launch of the Xinyuan rocket.

And because of the change of the world line, he did not attend the Boao Forum in Qiongzhou in 2015, which is one less than the original world line.

As far as Lin Ju knows, this trip to China will take about four days. On the 18th and 19th, he will discuss the construction of Tesla's production base in China, that is, the future super factory, in Shanghai. On the last day, he will come to Qiongzhou to see the super rocket.

Thinking of Ma's super factory, Lin Ju can't help but feel a little emotional.

The biggest impact of Tesla's super factory on China is the basic salary of local car companies.

In Aramco, the hourly wage of car factory workers is about 16 US dollars. If it is based on the later world of working four days and resting two days, the average working time per shift is 11.5 hours, which means that this salary will be 1,140 yuan per day in China.

Of course, this is actually impossible. Lao Ma once wanted to set the monthly basic salary of the Shanghai Super Factory at 8,000 yuan, but it was unanimously resisted by domestic companies. Under great pressure, it dropped to 5,400 yuan.

After all, the purchasing power is different, and the price conversion is also different. For domestic car companies with an average basic salary of 2,000 to 3,000 yuan, if they are forced to follow Tesla to raise the basic salary, it means a huge increase in costs.

The basic salary refers to the 8-hour work system and normal working days. The rest of the time is considered overtime. If you can get 5,000 to 6,000 yuan in salary, then most of it is brought by overtime. In this domestic environment, you can't make money with standard working hours.

In fact, companies in all countries have overtime. About 10 hours a day is the norm. The 40-hour or even less work system in Europe and the United States is just a reform of the standard work system, and the overtime hours have been increased to pay overtime pay.

Xinyuan is certainly different. As the company grows, Lin Ju offers workers a minimum basic salary of more than 6,000 yuan. It is one of the few domestic companies that can implement a five-day work week. There is no overtime on Saturdays and Sundays unless there is an urgent production task, and there are more additional benefits.

The Shanghai Super Factory has no impact on Xinyuan, but it has an impact on Xinan Automobile. The latter is not a large parent company that can make money by relying on its far-leading technological advantages. It must consider the labor of the automobile factory.

However, Xin'an, which is partly based on Xinyuan, has already surpassed ordinary car companies by a large margin. The gap is not big and it is mainly positioned in the mid-range and above market, with high profits. Other car companies can only rely on their own luck...

"In 2011, we were planning the module configuration of the space station. At that time, we called this module Experimental Module II, and the Shanghai team was in charge. In 2014, it was determined to be called "Mengtian". The cabin design is basically based on the optical system it carries."

The two experimental modules, Mengtian and Wentian, have been installed on two battle-hardened, black Xinyuan-2 rockets. At this time, the fairing is being prepared to be closed, and the experts involved in the development of the Fifth Academy are introducing it to Lin Ju.

"The cabin had not been manufactured at that time, but it was confirmed that it would be launched by the Long March 5, so the maximum diameter we designed was only 4.2 meters. Now the maximum diameter of the new Mengtian is 7.2 meters, and the diameter of the fairing is 8 meters.

Now its launch mass has increased by a full 20 tons, but it is actually not enough. The Shanghai team has expanded the size of the optical system to make the observation performance more than twice the original, and the power generation capacity has been expanded to 70KW. The space is enough, but the mass is exceeded.

After the launch, it will need to be launched again to add some cabin equipment to install. At that time, Mengtian should have an operating mass of 56 tons."

Lin Ju: "Installing equipment in the cabin? Will there be any trouble?"

"That won't happen. The cabin equipment to be installed later is the control part and the computer, not the most sophisticated optical part. And the most important thing is that the docking port size is still 2.5 meters square, and any equipment can be easily passed. Just be careful not to bump it. I believe in our astronauts."

Lin Ju nodded and continued to admire the huge experimental cabin before the fairing was closed. Due to its large diameter, an 8-meter fairing was used, which was 2 meters larger than the diameter of the rocket body of Xinyuan-2, and it looked spectacular.

Cooperating with the Space Administration to manufacture the Wentian and Mengtian experimental cabins is not just a simple case of Xinyuan making shells and inserting equipment for the Space Administration. It is worth learning about the installation essentials, preventive and redundant measures, and wiring in the cabin. The manufacturing of the axial cabin of Qianjin drew on these technologies.

In addition, Xinyuan also participated in the manufacture of an important part, the heavy-duty mechanical arm of the Wentian experimental cabin.

This mechanical arm can be used to transfer the cabin position when the docking port needs to be vacated, and can also be used to grab spacecraft or satellites.

For example, if the space shuttle cannot repair a large satellite in the future, it can be grabbed and sent to the space station for repair slowly. There is a position on the cabin to fix the spacecraft outside the cabin.

The maximum length of this mechanical arm reaches 26 meters, and it can bear 190 tons. The weight reaches 3.2 tons, and it is equipped with the first generation of AI control technology.

In the AI ​​state, the robot arm can capture the target through its own rich sensors without human control, and can accurately complete the task by simply inputting instructions.

Although Xinyuan's own highest chip technology is only 14nm, the potential of ternary chips in AI has been gradually tapped, and engineers are becoming more and more adept at it.
