I Am Just a Support Teacher

"Teacher, I thought of a new solution for aluminum-lithium alloy. It is very likely to be realized after demonstration. If it succeeds, the difficulty and cost of manufacturing aluminum-lithium alloy will be greatly reduced, and this new solution produces aluminum-lithium alloy. The overall performance of the alloy 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 doesn't like my idea at all, saying that I am fantastic, so I can't apply for research funding to do experiments. ."

"If you want to experiment with my new solution, you have to purchase and customize many special equipment. This requires a lot of money. Can you lend me 200 million, teacher? 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 for a while.

"My thoughts are like this..."

Later, during the video call, Zhou Qian stayed with Yang Xin to explain her thoughts and thoughts.

Moreover, Zhou Qian's remarks lasted 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 master the manufacture of aluminum-lithium alloy, but only the United States masters 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 was reduced by 2.2%, and the annual flight cost of each aircraft was also reduced by 2.2%.

Moreover, aluminum-lithium alloy is most importantly used in the structure of aerospace vehicles. It can effectively reduce the aircraft itself, thereby increasing the effective load. Each additional 1kg of the effective load can bring benefits of US$4,400 to 110,000.

If the Pangwu rocket uses a large amount of this material, Pangwu can bring more satellites or other materials into space, and the savings for each launch will be in the hundreds of millions.

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 passenger aircraft c919.

Limited by this, the Fat 5 carrier rocket that launched the Tianwen 1 Mars rover nine years ago has not been able to use advanced aluminum-lithium alloy materials. The carrying capacity has been somewhat stretched.

"Xiao Wei, do you think Zhou Qian's plan is possible?" After listening to Zhou Qian's explanation, Yang Xin asked Xiao Wei, the system wizard.

"Fifty points need to be deducted to answer this question." Xiao Wei said towards Yang Xin.

"All right, fifty is fifty." Yang Xin agreed.

He found that the current Xiaowei is no longer the same Xiaowei at the beginning, and now he has to score points with her for everything.

Fortunately, he has a lot of points now, and he is not short of those fifty points.

He decided that if Zhou Qian's idea is really possible, let alone two billion, he can borrow even one billion.

If it is not possible, he will think about it.

After all, although he makes a lot of money every year, this is not an excuse to make trouble.

With Yang Xin's promise, Yang Xin's points were soon deducted 50 points.

Then I heard Xiaowei say: "Host, Zhou Qian's thoughts and ideas are achievable, but this is considered a success, which is still much worse than the best aluminum alloy in the world.

However, the system has a better solution to improve on this solution, which can greatly improve the strength, hardness, corrosion resistance and other properties of aluminum alloy, which can definitely exceed the percentage of the most advanced aluminum alloy in the world. It’s about thirty. "

Finally, Xiao Wei said: "And only two thousand points are needed, and this plan can be redeemed for you."

"Two thousand points? Are you kidding me! Can I spend two thousand points for a material technology? Countries in the world have many materials that are backward. If I redeem them, I won't be in debt? I might as well cultivate more. Some geniuses come out, they will be able to research the best materials sooner or later." Yang Xin directly refused to say Xiaowei.

Hearing Yang Xin's words, Xiao Wei said: "Host, don't refuse it first, listen to what I said before you decide whether to exchange it or not."

Xiao Wei said to Yang Xin, "I just say a word. This technology was originally priced at 8,000 points. If it weren't for your student Zhou Qian to put forward a preliminary plan, it would be impossible to exchange 2,000 points for you. You have earned six thousand points by redeeming it now."

"Is that so!" Yang Xin was lost in thought when he heard Xiao Wei's words.

If you spend two thousand points to buy something with eight thousand points, it will naturally make a lot of money, but why does Yang Xin feel like being cheated?

"Host, do you need to redeem this technology?" Xiao Wei asked Yang Xin.

"I need to think about it." Yang Xin said.

"What is there to think about? You have earned two thousand points to exchange for eight thousand points." Xiao Wei 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." Xiao Wei said.

"Well, I'll redeem this technology." Yang Xin nodded and said.

"Ok."

With that, Yang Xin agreed, and soon his points were deducted two thousand.

His original more than 1,000 points, plus the 1,000 points for Tian Wenwen's honor award, total 2,648 points.

Now that two thousand points are deducted, his points are directly left with only 648 points.

As his points were deducted, soon, a set of the most advanced aluminum alloy technology was passed to his mind by the system~www.ltnovel.com~The system 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 turned out to be the addition of another metal scandium element to Zhou Qian's plan.

"Host, I didn't lie to you. If you didn't redeem this technology, do you know that you want to join the scandium element?

Also, this is not a random addition. It requires a very complicated operation process. If you were not able to exchange this mature technology directly in the system, you might not be able to study this technology in your entire life. "Xiao Wei said to Yang Xin.

Yang Xin calmed down a lot when she heard Xiaowei's words.

Indeed, as Xiaowei said, although the addition of scandium metal can greatly improve the performance of the aluminum alloy of Zhou Qian's plan, this is not something that can be imagined with a single shot.

Many important sciences and technologies in history were stuck there for a long time because they couldn't step into it.

For example, type printing has affected the entire world and directly promoted the technology of the European Renaissance.

Movable type printing has been invented for hundreds of years. Why didn't the ancient Chinese think of using lead for movable type printing?

Is the type technology difficult? No, because the ancients could even make copper type, which is much more difficult to make than lead type.

The most important thing is that some things limit people's 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 Xiaowei is right. If Yang Xin could not directly exchange this technology, can he know that adding scandium can greatly improve the performance of this aluminum alloy?
