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, the edge has traces of high-temperature ablation and oxidation, the whole is silvery-white, it looks like it is a little dirty, but in fact it can't be erased, it is the color of the material itself.

The metal surface is also laser-marked with four numbers 2201, which obviously belongs to the number of the verification machine.

The person who gave the gift said: "This is the J-20B model given to you by Chief Engineer Yang Wei, which was cut from the girders of the fuselage. ”

After some explanation, Lin Ju knew that the XW-9 engine interception version of the J-20 had actually made its first flight, and he was suddenly a little puzzled: "How did you cut the girder of the test machine?" What went wrong with the plane? ”

The person who came showed a wry smile: "Although the J-20B fuselage skin has withstood the test by considering the deformation at high temperatures, it has forgotten that the inside of the fuselage has also been subjected to high temperatures, and after 10 minutes of Mach 3.43 ultra-high-speed flight, the girder has almost been extended by 70cm to break through the skin."

Although the plane was safely landed, the girders had been irreversibly damaged and had to be scrapped, and the airframe needed to be redesigned, but the XW-9 performed very well without any problems. ”

“……”

"Say hello to him for me, I will not be able to return to Shuchuan for a while, I accepted the gift, I like it very much."

Lin Ju accepted the gift and calculated the time, and the old horse had already boarded the plane.

Ma Yilong's first stop in China was of course the magic capital, and he also came last year, but he only stayed for dozens of hours, and left in a hurry without looking at the rocket launch of Xinyuan.

And due to changes in the world line, he did not participate in the 2015 Qiongzhou Boao Forum, which was one less than the original world line.

Lin Ju knew that he would discuss Tesla's Huaguo production base in Modu for about four days, on the 18th and 19th, and on the last day, he would come to Qiongzhou to see the super rocket.

Thinking of Lao Ma's super factory, Lin Ju had to feel a little emotional.

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

In Aramco, the hourly wage of a worker in an automobile factory is about US$16, and if we take four days off and two days off in the future, the average working time per shift is 11.5 hours, which means that this salary is 1,140 yuan a day when moving to China.

Of course, this is actually impossible, Lao Ma once wanted to set the monthly basic salary of the Modu Super Factory at 8,000 yuan, but the result was unanimously boycotted by domestic enterprises, and the huge pressure 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 that the cost will rise significantly.

The basic salary refers to the 8-hour working system and normal working days, and the rest of the time is counted as overtime, and you can get 5 to 6,000 wages, so most of them are brought by overtime, and you can't earn money with standard working hours in this domestic environment.

In fact, there is overtime in enterprises in various countries, about 10 hours a day is the norm, and the working system of 40 hours a week or less in Europe and the United States is only a reform of the standard working system, increasing the overtime hours and paying overtime pay.

Xinyuan is of course different, as the company is getting bigger and bigger, Lin Ju gives workers a minimum basic salary of more than 6,000 yuan, and it is one of the few five-day work systems that can be implemented in China, there is no emergency production task on Saturdays and Sundays, no overtime, and more supplementary benefits.

The Modu Super Factory has no impact on Xinyuan, but it has an impact on Xin'an Automobile, which is not a big parent company that can rely on its leading technological advantages to make money, and must consider the labor of the automobile factory.

However, some of the Xin'an benefits adhering to Xinyuan have also surpassed ordinary car companies, the gap is not large, and the positioning is mainly in the mid-range market, the profit is higher, other car companies can only ask for more blessings......

……

"In 2011, at that time, we were planning the configuration of the space station, at that time, we called this module Experimental Module II, and the Modu team was in charge, and it was determined to be called 'Mengtian' in 14 years, and the cabin design was basically carried out around the optical system it carried."

The two experimental cabins of Mengtian and Wentian have been loaded with two battle-hardened and swarthy Xinyuan-2 rockets, and they are preparing to close the fairing at this time, and the experts involved in the development of the Fifth Academy are introducing Lin Ju.

"At that time, the module had not yet been manufactured, but it was determined that it was the launch of the Long March 5, so the maximum diameter of our design was only 4.2 meters, and now the maximum diameter of Xinmengtian is 7.2 meters, and the diameter of the fairing is 8 meters.

Now its launch mass is a full 20 tons more, but in fact, it is not enough, the magic team has expanded the size of the optical system to make the observation performance more than twice the original, and the power generation power has been expanded to 70KW, but the space is enough but the quality has been exceeded.

After the launch, it is necessary to play again to add some equipment in the cabin and install it, and at that time Mengtian should have a running mass of 56 tons. ”

Lin Ju: "Installation equipment in the cabin? Will there be trouble? ”

"That's not going to happen, the follow-up installation of the cabin equipment is the control part and the computer, not the most sophisticated optical part, and the most important thing is that the interface size is still 2.5 meters square, any equipment can easily get through, be careful not to bump it, I believe in our astronauts."

Lin Ju nodded, and continued to admire this huge experimental cabin for the last time before closing the fairing, because the diameter was too large, the 8-meter fairing was used, which was 2 meters larger than the diameter of the rocket body of Xinyuan 2, which looked spectacular.

The cooperation with the space agency to manufacture the Wentian and Mengtian experimental modules is not just a simple new Yuanyuan shell space bureau plug equipment, for the equipment installation essentials in the module, prevention and redundancy measures, cable management and other aspects are worth learning, the axial module manufacturing of the Qianjin is a reference to these technologies.

Moreover, Xinyuan also participated in the manufacture of an important part, the heavy robotic arm of the Wentian experimental module.

This robotic arm can be used to free up the position of the transfer module of the docking interface, and can also be used to grasp ships or satellites.

For example, if the space shuttle cannot repair the large satellite in the future, it can be captured and sent to the space station to be repaired slowly, and the module section is used to fix the position of the extravehicular spacecraft.

The robotic arm has a maximum length of 26 meters, can bear a weight of 190 tons, and has a dead weight of 3.2 tons, and is equipped with first-generation AI control technology.

In the AI state, the robotic arm can capture the target through its own rich sensors without human control, and only need to input instructions to complete the task accurately.

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