Rebirth 2008: I Can Make Money Reading Chapter 531

April 17, 2016

Mu Yang came to the satellite project team on the 7th floor of the aviation laboratory building to check and accept the samples.

In the room of the 702 laboratory, two Xingdou-1 satellites have been placed, and one of them has deployed solar panels.

Lu Ding, the technical manager, knew that the chairman was coming, so he was waiting in the laboratory today, and when he saw someone coming, he went up to greet him respectfully.

Mu Yang nodded after seeing Lu Ding, and first observed the actual satellite.

The Xingdou-1 sample has a gross weight of 351 kilograms, a length of 2.6 meters, and a width of 1.40 meters. This size refers to the size of the solar panels when they are contracted, not the size of the solar panels when they are unfolded.

The length and width are large, but the thickness is very thin, about 9 centimeters thick. It looks like a laptop from a distance. After the solar panels are folded, the total thickness is only about 24 centimeters.

The total space occupies about 0.87 cubic meters.

After the solar panels enter the space orbit, the solar panels will be about 10 meters long on one side. It is somewhat like Musk's Starlink satellite, but the structure is more compact. This is why Xinghai Group uses metal 3D additive technology to manufacture.

Of course, although Xingdou-1 has a compact structure, the materials are different, so the overall mass is heavier.

The fairing of Xingkong-1 is relatively long, and the internal load space is about 346 cubic meters. The theory is that it can carry 398 Xingdou-1 satellites.

But in fact, because the satellites are folded and stored, and there is a mechanism for launching satellites, it is estimated that 340 satellites can be loaded. The total weight of the satellites is about 119.34 tons, plus other additional weights, a total of about 125 tons.

[Reminder: After rigorous calculations, the liquid oxygen and liquid hydrogen under full load already occupy 502 cubic meters of space, plus others, it is found that the space of the original Xingkong No. 1 is far from enough, and the original design data is not rigorous enough. Sorry, the current length has been revised It is 58 meters long and has a straight cylindrical structure without steps. The diameter of the cylinder is 4.8 meters. 】

After reading the actual objects, Mu Yang took a page of catalog from Lu Ding, which marked "Xingdou-1 Star-ground Docking Test Method of Xinghai Group", "Star-ground Equipment Delay Measurement Method", "Xingdou-1 System Ground Monitoring Station Maintenance Regulations" "" "Star Dou No. 1 Payload Orbital Test Method" and other 21 standard lists, which are internally called "enterprise specifications".

There are many standards, so Mu Yang asked Lu Ding to take one of the enterprise specifications "Star-Earth Docking Test Method" to review on the spot.

This specification is dozens of pages thick, Mu Yang looked through it roughly, and found that there was no random editing or copying from others, so he did not check other specifications.

He attaches great importance to norms. This is the technology and experience of an enterprise, which must be passed on.

Mu Yang solemnly explained: "Manager Lu, in addition to the technical specifications, everyone should summarize the experience in the development process, write down the good and the bad, especially the key points, and don't write indiscriminately, so that later generations can read it. Learning, so as not to mislead others, this must be strictly enforced, the time is not urgent, but must be taken seriously.”

Mu Yang compiled technical specifications in his previous life, and sometimes he was in a hurry. In order to meet the requirements of the company, some data was just made up. People who didn't do it by themselves couldn't tell the difference. .

Mess with the data, such as welding current and voltage. As a result, others have tested according to his data. Even if the current error is 10A, it will be found that the welding quality cannot reach the expected effect.

"Okay, I understand." Lu Ding said after taking over the specifications that the chairman had read. Mu Yang nodded and continued to check and accept Xingdou-1 satellite.

"After the satellite is launched into the sky, the key is the solar panels. If it cannot be deployed normally, the satellite will be useless. You need to do more experiments, and even artificially interfere with the test."

Existing satellite solar panel deployment is generally by memory metal, when the operating temperature reaches a certain temperature, it will automatically unfold according to the original set shape.

Alternatively, a pyrotechnic mechanism is used to fold the solar panel before launching and compress it with a spring, and then lock it with a pyrotechnic mechanism.

When unfolding, the pyrotechnic mechanism is instructed, the explosive bolt is detonated, the locking mechanism is exploded, and the sailboard is unfolded under the action of the spring force.

This process seems simple, but for satellite access to real

The working status of the company is a very important link. There are failure cases in various countries. A good satellite becomes a junk satellite because the solar panels cannot be opened.

Both plans have their pros and cons, and it's hard to say which one is the best. The Xinghai Group adopted the former plan.

"According to the test plan, we plan to conduct no less than 100 tests, and then artificially interfere with the test."

"Well, yes." Mu Yang nodded in approval.

After the samples are manufactured, we still need to discuss together to see where we can optimize.

Before it is manufactured, some problems that are easy to be overlooked cannot be seen in the light design drawing.

The next day, Mu Yang asked Lu Ding to organize a meeting of the satellite project team to count the problems that occurred in satellite manufacturing, analyze the problems that may be encountered in mass production, and further optimize.

The sample analysis meeting lasted for a day, and Mu Yang made the final review in the afternoon, and also put forward some suggestions for rectification.

There are 20 or 30 problems, big and small, and Mu Yang gave them seven days to optimize.

Another seven days later, on April 25, the optimized samples came out and were reviewed again.

This time the review was finally done.

"Start with a small batch of 100 pieces of production, your R&D department must follow the production, don't sit in the office or laboratory, there may be some problems that we haven't found out.

If something is good, whether it can be produced is also critical.

After the small batch production is no problem, take five satellites to launch, and the rocket launch base will finish the launch soon. When they have real data from their side, only after the satellites are launched into the sky and used, will they know whether they are useful or not.

After it is confirmed, we will decide on mass production. "Mu Yang put forward new requirements to Lu Ding, "The production workshop can't increase the production capacity quickly, so be on the safe side.

"Okay, Chairman, I understand."

Lu Ding nodded solemnly. The production cost of 20,000 Xingdou No. 1 is tens of billions. If there is a problem, the loss will be huge.

After inspecting the satellite laboratory, Mu Yang came to the satellite production workshop, found the production manager, and asked him about the production preparations.

"Chairman, there are still a lot of poor materials. Currently, we can only guarantee the production of 1,000 satellites."

"Well, how long is it estimated that the materials will be ready?"

"In two months, we have to produce as many materials as we need. We need to produce 20,000 pieces within half a year. We are not prepared in all aspects. We have to transfer personnel from other workshops. After the production of satellites is completed, most of the production personnel will return to their original positions."

"The situation is urgent, do your best." Mu Yang said, this situation is considered very good.

Even if Ugly Country knew that they wanted to prepare tens of thousands of satellite materials, and then produce these tens of thousands of Starlink satellites, Mu Yang felt that they would not be able to do it in a year.

Muyang doesn't give the company's project team so much time to debug the satellites. They will launch first, and exchange time with money. If it is found that the satellites are not usable after launch, that's normal, as long as they are controlled within a small probability range.

A few days later, on May 1,

The Xinghai Group is on holiday, but on the west coast of the Atlantic Ocean, Musk's Spex company detonated a depth charge, which caused huge waves in the media.

Their company announced that the Falcon 9 FT carried 11 OrbG2 satellites and launched them to LEO at the Air Jun base in Cape Canaveral, making history by successfully recovering the first-stage rocket on land for the first time.

Although Xinghai Group and SpeX Company both recover rockets, Xinghai Group recovers the whole rocket, while SpeX Company recovers the first-stage rocket, Falcon 9 is the second-stage rocket, and the second-stage rocket and fairing are not recovered.

However, the Falcon 9 itself is also being iteratively upgraded. It is the first to recover a first-stage rocket, and it is estimated that it is also the first to reuse a first-stage rocket and the first to reuse a cargo spacecraft.

Ugly country media carried out enthusiastic reports and spread to Hua country's domestic media. Domestic netizens had to admire this company.

"Some companies only make money and don't engage in scientific research. Look at other high-tech companies. The goal is the stars and the sea.

"Domestic companies like to engage in marketing, who will engage in technology. It's not that marketing is bad, but that we must focus on the key points."

"In China, it seems that we can only rely on the Xinghai Group, but there is no news about the Xinghai Group recently."

"Mushen hasn't shown up very much in the past one or two years. I heard that he is busy with scientific research all day long. The chairman of this kind of company is worth learning from domestic companies, instead of spending too much time on marketing."

SpeX Space Company launched a satellite, and someone thought Mr. Liu was accidentally injured. After seeing the media news, he was a little angry: You slandered me, slandered me!

It has nothing to do with him, and there is more than one in the country who thinks that the company is like this, why is it targeting him.

In fact, he knows that his good days are running out. Since the Xinghai Group announced its plan to invest 200 billion yuan into the computer industry at the beginning of the year, the water in the computer industry has become more turbid.

Now, all computer brand manufacturers are clearing their inventories as soon as possible, and the price reduction process will be completed this year. After all, the situation is unknown. If Xinghai Group really releases new products, it will have a great impact on the computer industry.

They dare not bet that the Xinghai Group will definitely have no problem manufacturing computer CPUs. It is a matter of time. It is estimated that the product will be produced this year. Now it has cooperated with various computer component manufacturers, and even the four-star company has confirmed the cooperation and implemented it in Huaguo Green City. That is, Mu Yang's hometown invested in the construction of a liquid crystal factory.

Other manufacturers who have confirmed to sign a cooperation agreement with Xinghai Group have followed the example of Four Star Company and invested in building factories in Muyang's hometown.

SpeX successfully recovered the rocket, and several students of Mu Yang couldn't understand the teacher's operation.

"Sister, it should be the teacher's company that first created the history of recovering rockets?" He Wang, Mu Yang's second-term student, asked Leng Han.

Leng Han rolled his eyes smartly, pondered for a while, and said in a deep voice: "It's not true, it's just a test satellite, and the satellite has not yet been launched. However, even if the satellite is successfully launched, I don't think the teacher will Choose to publish." "Why?"

"Teacher likes to keep a low profile, unlike that foreigner who always has nothing to hide." "This is true."

"It's good to understand, anyway, as students, we can't get on the stage yet, just watch them act."

Leng Han nodded. In fact, she didn't quite understand why the teacher didn't want to announce the rocket launch.

She didn't know about the Starnet project, but she also knew about the confidentiality issue. As long as it involved scientific research, they would not disclose it to the outside world or their family members.

In the Xinghai Group, there is a clear regulation that scientific researchers are forbidden to discuss work matters when they leave the laboratory and office, and it is forbidden to disclose the details of scientific research projects to the outside world.

Leng Han and the others discussed casually in the laboratory, but when they left the laboratory, they would not discuss what they were doing in the Xinghai Group even if they were at school.

When students asked what they were doing in Xinghai Group, they would only answer about studying, and it would be inconvenient to answer if there were too many.

Xinghai Group recruits a large number of students from Jiangsu and Zhejiang University every year. It is the company or unit that has the largest number of graduates from Jiangsu and Zhejiang University.

Xinghai Group's satellites are being optimized in full swing, and another department has good news that the samples of the computer chip Zixing C11100 developed have come out.

Zixing C2 and C3 are later.

But to achieve mass production, it is estimated that it will be by the end of the year.

CPU proofing is to make a whole 12-inch wafer, theoretically four hundred Zixing C11100 chips can be manufactured.

The test doesn't take so much. After packaging, the research staff in the chip department first replace their work computers with new computer chips, in the name of checking the performance of the chip by the way.

It has to be said that the Zixing C11100 has passed the running test and is much more powerful than most CPUs on the market, which caused these researchers to be uneasy, and the laboratory exclaimed again and again.

If the top CPU Core i77700 on the market has a score of 10,000, then Zixing C11100 has a score of 15,000. It is possible to sell it for 10,000 yuan, but the company's positioning is at the level of 2,000 yuan. This is to smash the international CPU market. It's a good show. read.

Now, they are still developing more powerful C2 and C3, and when the company's new product is announced, it will definitely shock the industry personnel, and Yingtel will be finished.

"Our chip C1 is really good, 17 is much different, Gou Ri's Yingtel, I can't wait to go out of business soon.

"It's difficult for this company to close down. The ugly country will have countermeasures and impose high taxes on our company's chips."

"As long as it goes on the market, UU Reading www.uukanshu.com, I will replace the CPU of the computer at home."

"I think it's better to wait for the C3 to come out. I'm going to eat dirt and toss one."

"Leader, should there be discounts for employees buying company-branded computers?" a researcher asked the team leader.

"It should be. How much discount can be obtained? We will not know until the plan is made."

"Our houses, food, cars, mobile phones, computers, children's schooling, medical care, etc. are all owned by the company. The company is Niubi."

"Even looking for a wife is helped by the company, haha."

Most of these chip researchers are computer enthusiasts. The computers provided by the company are all high-end machines, but they do not meet their needs.

They usually test the high-end chips on the market, the more they know there are good things, and they are used to using good things, the general high-end chips are difficult to satisfy their appetite.

For them, it is most suitable to give them a supercomputer, and now some employees plan to build servers for themselves.
