The magnitude of the Yushu earthquake was very high. Fortunately, because the Qinghai area is vast and sparsely populated, the number of people affected was far less than that of Wenchuan.
However, the average temperature in the Yushu area is still very low at this time, so the focus of disaster relief is naturally to resettle the victims.
Professional matters should be left to professionals. Non-professionals only need to provide human and material support and shout cheers from the sidelines.
Even so, Zhou Yan was still not idle.
Whether it was Xu Chongsheng or Deng Zhuo, after knowing that Zhou Yan was in the capital, they called and sent emails from time to time to ask for instructions, which made Zhou Yan very uncomfortable when he was taking a break from his busy schedule.
Especially Xu Chongsheng, who called Zhou Yan every three days and made Zhou Yan miserable...
"Mr. Zhou, Shimen Special Steel and the Second Machine Tool Factory are officially on the right track. Should we think of a way to do a wave of marketing? After all, if you are drunk, you will be afraid of the alley!"
As soon as Xu Chongsheng finished speaking, the system in Zhou Yan's head that had been dormant for half a year suddenly popped up.
"Ding!"
[Professional and technical trial tasks (2) are now released.
The task is to use what you have learned to design a work that best demonstrates the basic mechanical processing capabilities.
Mission reward: Red Empire’s turbine engine series.]
Turbine engine?
This concept is a bit broad, but it covers helicopter turboshaft engines, turbofan engines, gas turbines, and fuel-efficient turboprop engines.
Are you planning to empty out the legacy of the Red Empire?
Although Great Beauty Country stands out in terms of turbine engine technology, Red Empire is not bad either and has rich products. Especially the turboshaft engines are no worse than similar products from Beautiful Country; moreover, turboshaft engines have always been
The shortcomings of my rabbit.
"This mission must be accepted! The system has given us too much!"
However, Zhou Yan didn't have much inspiration on how to complete the trial mission. After thinking about it for a long time, he couldn't come up with any good ideas...
My girlfriend's class for the day is over.
At around three o'clock in the afternoon, it was not the rush hour, and the first traffic jam was normal. In order to prevent leaving a blood clot on the capital's traffic vessels, Zhou Yan parked his car at his usual parking place - a hotel near Ken University.
in the parking lot.
After a while, seeing that it was time to finish class, Zhou Yan called his girlfriend: "Ruoshu, I'm waiting for you at the same place!"
A few minutes later, Qin Ruoshu appeared on the street. Zhou Yan started the car and went to meet her.
"Oh, I'm so exhausted!"
After getting in the car, the eldest lady did not fasten her seat belt as usual, but approached Zhou Yan with a smile: "Hubby, give me some encouragement!"
As he said that, Qin Ruoshu's little hand was about to move towards Zhou Yan's face...
"Young man, are you trying to play this with me?" Zhou Yan smiled and grabbed Qin Ruoshu's hand. He glanced at it and saw that his index finger was covered with black ink stains left by a gel pen.
"Hehe... I've been discovered!" Qin Ruoshu sat back on the seat angrily and fastened her seat belt obediently.
"Ruoshu, I remember that our stationery is all brand-name goods. This shouldn't happen, right?"
"I forgot to bring it," Qin Ruoshu smiled helplessly, "I had to borrow one from Lao Li, and it ended up like this..."
Looking at his girlfriend's little hack, Zhou Yan suddenly remembered the short video he had watched before coming back: Before 2020, my rabbit's ballpoint pens and gel pen tips were basically imported, although the unit price of the gadgets
It's not high, but the annual import volume is quite a lot.
Typical "the harm is not great, but the insult is not small".
Then let’s fill in the gaps!
At night, after putting his girlfriend to sleep, Zhou Yan sank his consciousness into the virtual space.
If you want to make a ballpoint pen tip, materials are the first hurdle.
For foreign ballpoint pen tips, the front ball is made of tungsten carbide, while the ball base at the back is made of easy-to-cut high-strength steel wire.
On Zhou Yan's side, he also wanted to use tungsten carbide for balls: Shimen Special Steel already has a workshop specializing in the production of tungsten carbide turning tools, and it would be enough to add a little more process flow.
As for the free-cutting steel wire used to carry the ball base, Shimen Special Steel also produces it.
After the most basic material problem is solved, the next processing machinery and technology are the most troublesome.
The size of the ball at the tip of a ballpoint pen is only a few hundred microns, and the accuracy requirement reaches the micron level.
That's all. What's more troublesome is that the base of the ball is machined, and there are five slots in the hole that holds the ball for the circulation of ink.
Fortunately, the machine tool for processing ballpoint pen tips does not need to be too complicated, it only requires sufficient accuracy, and Zhou Yan still has a reference.
After entering the virtual space, Zhou Yan was just stunned for a moment, then went straight to his database and found the process roadmap of the photolithography machine.
The technology is available, and Shimen Special Steel's production line is sufficient to produce special steel that can handle micron-level machining...
The rest is much easier to do: according to the shape and structure of the ballpoint pen, design a set of processing technology starting from raw materials, and then refine it into a production line...
The next day, Zhou Yan sent the production line information to Xu Chongsheng. After a long time, Xu Chongsheng did not respond. Zhou Yan thought that this guy didn't have time to read it.
Who would have thought that at around eight o'clock in the evening, Xu Chongsheng suddenly called home, his voice full of excitement: "Mr. Zhou, did you know that the country is preparing to launch a research project on ballpoint pen tips!"
Zhou Yan naturally understands the significance of national research. Although he is a little happy, he still suppresses his inner excitement: "If we take these materials out now, will it cause public outrage?"
"No, we have to rely on our ability to make a living! Besides, the profit of the ballpoint pen tip is not very big, and it is very troublesome to process..." Xu Chongsheng was very excited, "The first phase of the project at Shimen Special Steel is about to begin.
It’s completed, now we can organize the Second Machine Tool Factory to conduct public relations on the ballpoint pen tip production process, but..."
This chapter is not over yet, please click on the next page to continue reading! Zhou Yan naturally knows what the second machine tool factory lacks: "I will tell Deng Zhuo and ask the lithography machine to provide certain support!"
After making arrangements, Zhou Yan went back to digest the reward from the ballpoint pen tip: the turbine engine of the Red Empire.
Red Empire has a strong background in turbine design. There are more than a dozen large aero-engine design bureaus...
The parent company of the RD-93 turbofan engine used by the JF-17 Xiaolong is the Klimov Design Bureau; the parent company of the D30KP2 engine equipped on our rabbit H6K and Y20 is the Soloviev Design Bureau; used by the Mi-17
The TV3-117 turboshaft engine is designed by Isotov Design Bureau.
The famous "Three Uncles" - the Lyurica Design Bureau, the birthplace of the AL-31F turbofan engine; the Kuznetsov Design Bureau, which specializes in bomber engines; and the Tumansky Design Bureau, which made the beautiful capital tremble during the Cold War.
; and the creation of the An-225 and An-124 engines for the D-18, later renamed the Progressive Ivchenko Design Bureau.
Zhou Yan also didn't expect that the system would send him a graduation gift package when he graduated from university.
Not to mention anything else, the information on the D-18 turbofan engines used on the An-124 and An-225, as well as the D-136 turboshaft engines used on the Mi-26, is what Zhou Yan is in urgent need of right now.
The An-124, An-225 and Mi-26 that Zhou Yan asked Frank to get back from WKL were basically picked up like rubbish. Although these aircraft have been made by people from the West Aircraft Company at Yanliang Airport.
Great health care, but after all, it is all things that have been gathering dust for many years, and there are not even spare parts. If you don’t have the information in hand, there will be no place to repair it if it breaks...
