I Am Just a Support Teacher
Chapter 278 The Most Advanced Aluminum Alloy Technology
"Teacher, I thought of a new scheme of aluminum-lithium alloy, which is very likely to be realized after demonstration. If successful, the difficulty and cost of manufacturing aluminum-lithium alloy will be greatly reduced, and the aluminum-lithium alloy produced by this new scheme will Alloy, the overall performance may be able to catch up with the best aluminum-lithium alloy in the United States."
Zhou Qian said to Yang Xin: "I originally told my current supervisor about this idea, but because I am only a doctoral student, my supervisor is not optimistic about my idea at all, saying that I am whimsical, so I can't apply for research funding to do experiments. .”
"And if you want to experiment with my new plan, you have to buy and customize a lot of special equipment, which requires a lot of money. Teacher, can you lend me 200 million? I will definitely find a way to return the money to you in the future." Zhou Qian said to Yang Xin.
"Can you tell me your thoughts carefully?" Yang Xin asked Zhou Qian after thinking about it.
"My idea is this..."
Later, during the video call, Zhou Qian stayed with Yang Xin to explain her thoughts and ideas.
And what Zhou Qian said, it took several hours.
After listening to Zhou Qian's explanation, Yang Xin also had a great understanding of what Zhou Qian said.
Aluminum-lithium alloy is currently the most popular material for aviation aluminum in the world. At present, there are many countries that have mastered the manufacture of aluminum-lithium alloy, but only the United States has mastered the aluminum-lithium alloy that can be used in aerospace.
A few years ago, after Boeing aircraft used advanced aluminum-lithium alloy materials, the weight was reduced by 15%, the fuel was saved by 5.4%, the cost of the aircraft will drop by 2.2%, and the annual flight cost of each aircraft will also be reduced by 2.2%.
Moreover, the aluminum-lithium alloy is most importantly used in the structure of the aerospace vehicle. It can effectively reduce the aircraft itself, thereby increasing the payload, and every 1kg increase in the payload can bring benefits of 4,400 to 110,000 US dollars.
If the Fat Five rocket uses a large amount of this material, Fat Five will be able to bring more satellites or other materials into space, and each launch will save hundreds of millions of dollars.
The United States has restrictions on the export of advanced aluminum-lithium alloys to China. The only channel that is open and can be imported in small quantities is the aluminum-lithium alloy material used in the body of the domestic airliner C919.
Restricted by this, the Fat 5 carrier rocket that launched the Tianwen-1 Mars probe nine years ago has not yet been able to use advanced aluminum-lithium alloy materials, so it has no choice but to settle for the next best thing, using mainstream aluminum-copper alloys, resulting in Carrying capacity has always been somewhat stretched.
"Xiaowei, do you think Zhou Qian's plan is possible?" After listening to Zhou Qian's explanation, Yang Xin asked Xiaowei, the system elf.
"Fifty points will be deducted for answering this question." Xiao Wei said to Yang Xin.
"Okay, fifty is fifty." Yang Xin agreed.
He found that the current Xiaowei is no longer the Xiaowei at the beginning, and now she wants points for everything she does.
Fortunately, he has a lot of points now, and he doesn't lack those fifty points.
He decided that if Zhou Qian's idea was really possible to realize, then he could borrow not only 200 million, but even 1 billion.
If there is no possibility of realizing it, he will have to think about it carefully.
After all, although he makes a lot of money every year, it is not an excuse to use it for nothing.
Following Yang Xin's agreement, Yang Xin's points were deducted fifty points soon.
Then I heard Xiaowei say: "Host, Zhou Qian's thoughts and ideas can be realized, but even if this is successful, it will still be much worse than the best aluminum alloy in the world.
However, the system has a better solution based on this solution, which can greatly improve the strength, hardness, corrosion resistance and other properties of the aluminum alloy, which can definitely exceed the performance of the most advanced aluminum alloy in the world. About thirty. "
Finally Xiaowei said: "And only two thousand points are needed, this plan can be exchanged for you."
"Two thousand points? Are you kidding me! Can I spend two thousand points for a material technology? The country is backward in many materials in the world,
If I exchange them all, I won’t be in debt, right? I might as well cultivate some geniuses, and sooner or later they will be able to research the best materials. "Yang Xin directly refused Xiaowei.
Hearing Yang Xin's words, Xiaowei said: "Host, don't refuse yet, listen to me and then decide whether to exchange or not."
Xiaowei said to Yang Xin: "I just want to say one thing. This technology was originally priced at 8,000 points. If your student Zhou Qian hadn't proposed the early plan, it would be impossible to exchange 2,000 points for you. Your redemption now is equivalent to earning 6,000 points."
"Is that so!" Hearing Xiaowei's words, Yang Xin fell into thinking.
If you can buy something with 8,000 points for 2,000 points, it's a big profit, but why does Yang Xin feel like he's being cheated?
"Host, do you need to exchange this technology?" Xiaowei asked Yang Xin.
"I need to think about it." Yang Xin said.
"What's there to think about? You've made a lot of money by exchanging 2,000 points for 8,000 points." Xiaowei said.
"Are you sure that the technology I exchanged can make the performance of aluminum alloy 30% higher than that of the best aluminum alloy in the world?" Yang Xin asked Xiaowei.
"This is natural, at least 30% increase." Xiaowei said.
"Okay then, I'll exchange this technology." Yang Xin nodded and said.
"OK."
Then, Yang Xin agreed, and soon his points were deducted two thousand.
His original more than 1,000 points, plus the 1,000 points that Tian Wenwen received as an honor reward, totaled 2648 points.
Now deducting 2,000 points, his points are only 648 points.
As his points were deducted, soon, a set of the most advanced aluminum alloy technology was transferred to his mind by the system.
"The system, you lied to me." However, after learning the details of this technology, Yang Xin suddenly became a little angry.
The so-called improved version of the technology is actually just adding another scandium metal element to Zhou Qian's plan.
"Host, I didn't lie to you, if you hadn't exchanged this technology, would you know to add scandium element?
Also, this is not added randomly, it requires a very complicated operation process, if you can't directly exchange this mature technology in the system, you probably won't be able to research this technology in your lifetime. "Xiaowei said to Yang Xin.
Hearing Xiaowei's words, Yang Xin calmed down a lot.
Indeed, as Xiaowei said, although the addition of scandium metal can greatly improve the performance of the aluminum alloy in Zhou Qian's plan, it is not something that can be figured out with a slap in the head.
Many major science and technologies in history have been stuck there for a long time because they couldn't make a step forward.
For example, movable type printing, which has influenced the whole world, is a technology that directly promoted the European Renaissance.
Movable type printing has been invented for hundreds of years, why did the ancient Chinese never think of using lead for movable type printing?
Is the technique of movable lead type difficult? No, because the ancients could even make copper movable type, which is much more difficult to manufacture than lead movable type.
Most importantly, something keeps people thinking.
The same goes for firearms. Foreigners used them as weapons, but the ancient Chinese only thought of using them to set off fireworks.
So what Xiaowei said is not wrong. If Yang Xin could not exchange this technology directly, would he know that adding scandium can greatly improve the performance of this aluminum alloy?
