I Found A Planet

Virtual factory!

Make the impossible possible.

And there is an example of Zhongxin International "winning 7nm in eight months".

He Jinlong believed what the father and son said.

After all, Zhongxin International’s breakthrough is simply an industrial myth. Up to now, many people still think it is not true, and think it is a commercial scam... There are many related articles on the Internet. For example, Fang Zhouzi, a famous fighter against counterfeiting, wrote "Ten Questions about Zhongxin's 7nm Chip", this article had a great impact and even caused Zhongxin's stock price to plummet.

He Jinlong read that article, and after reading it, he was also full of doubts.

But now, the doubts in his heart disappeared, and he got the best answer.

It is indeed possible to create an industrial myth with the magical virtual factory technology!

"Mr. He, the virtual factory technology can't be released to the public yet. I hope you can help keep it secret. It's better not to let too many people know about this technology."

Chen Jin exhorted.

"Okay, I'll keep my mouth shut!"

...

the next day.

Commercial Aircraft Engine Company.

Tan Ruisong, the chairman of Shangfa Company, who has recently felt a sudden increase in pressure due to the ban on the sale of LeapX engines in the West, received a call from Mr. He of COMAC yesterday.

"How can it be?"

Hearing the virtual factory technology, his first reaction was shock and disbelief: "Is it possible for computer simulation technology to be so powerful?"

He Jinlong had to explain a bit, and also cited the example of Zhongxin International.

Tan Ruisong was very convinced.

Immediately said: "I will go to Xinghai Technology tomorrow to discuss cooperation with Mr. Chen!"

...

Because the headquarters of Shangfa is also in Shanghai.

early in the morning.

Tan Ruisong drove to the downstairs of the headquarters of Xinghai Technology.

After waiting for nearly two hours, I finally saw Chen Jin.

meeting room.

Tan Ruisong, who was sitting opposite Chen Jin, couldn't wait to ask: "Mr. Chen, has your company's 'virtual factory' technology really reached the level of simulating physical research and development?"

Chen Jin shook his head: "Hearing is believing, seeing is believing. In this way, I will give you a TC9000 computer for trial use, which is equipped with the 'Virtual Factory 1.0' technology. Your company will send a group of engineers to assemble it in the virtual factory. Try one engine, and directly see if the simulated environment is far from the actual error."

"good!"

afternoon.

A technical team composed of hundreds of engine experts sent by Shangfa Company entered the fourth R\u0026D factory of Xinghai Technology.

Due to the smaller size of the engine.

Moreover, the CAD industrial design drawing can be imported into the virtual factory to directly generate the engine, and the expert team assembled an engine in just a few hours.

that night.

They got the first batch of valuable data.

"Useful, really useful!"

"The difference between the engine thrust and the actual one is less than 0.1KN, and the change rule of the thrust is basically the same."

"Increase the fuel supply, and increase the thrust to about 148KN...Hey, it happened, and the engine interval surge problem also appeared here, indicating that our engine does have obvious design flaws."

"Continue to increase the fuel supply and see how long it can run under extreme conditions?"

About ten hours later.

"Boom~"

In the virtual factory, the overheated engine exploded into a pile of debris.

An expert who stared at the experimental data and stayed up almost all night said: "Almost, all the experimental data are similar to the real situation."

so……

Everyone looked at each other in blank dismay, and then couldn't hide their joy and excitement.

Some even couldn't help but shed tears.

"We have been scolded too much and blamed too much in these years."

"It's not that we don't work hard, but that the annual funding of 1.5 billion given by the higher authorities is too little."

"According to the plan, the CJ-1000 engine should have been put into commercial use last year, but because the main technical indicators are obviously inferior to the LeapX engine, it needs to continue to improve, and it will take more than five years to catch up... But when we catch up, the West will Well, a more advanced engine came out again, but it never caught up.”

"Now we have hope, we see the hope of catching them!"

"Sacred weapon, this is really a divine weapon!"

good.

deja vu.

The dilemma faced by the Z national engine is almost exactly the same as that of the chip industry.

The exploration of advanced chip manufacturing process is to constantly adjust the production process...it takes a lot of time.

The development of the engine needs to burn a lot of money.

The one-year budget of more than one billion yuan, excluding some personnel expenses, is only enough to produce more than a dozen verification machines and do more than 10,000 hours of tests. The average hourly test cost is about 100,000.

This seems quite impressive, but with the current efficiency of Shangfa, the number of verification machines must be increased to more than 30, and the annual test hours must reach 30,000+, so that it is possible to produce the same technology as the LeapX engine by 20X5 years ago Horizontal CJ-1000.

It means that the annual funding has to increase to more than 3 billion.

However, although country Z has a large industry, it also has a lot of expenses. In terms of engine development, it is impossible to have "unlimited funds".

However, with the virtual factory, the predicament of Shangfa Company will be fundamentally improved immediately.

As long as the computing power of the supercomputer is large enough, in the virtual factory, one hundred or one thousand sets of test benches are placed, and each test bench is equipped with an engine. Experiments are carried out at the same time, adjustments and optimizations are made continuously, and the engine is ruined. Immediately generate another...

The money and time saved by developing the engine in this way may be even more exaggerated than chip research and development.

In about half a year, it is not impossible to take out a qualified CJ-1000 engine and completely solve the problem within a year!

...

"Mr. Chen, how much is it? How much does your company charge for the use of a virtual factory?"

Tan Ruisong asked, he no longer doubts the power of the virtual factory, and now he just wants to ask about the charging standard!

"I'll give you two choices."

Chen Jin said: "The first one is to rent a TC900 with a computing power of less than 1 trillion operations per second. I will charge you a friendly price, and you can just pay 100,000 yuan for electricity per day. This price should not be expensive, right?"

"Not expensive and not expensive!"

Tan Ruisong shook his head, this is simply too cheap!

"However, the computing power of TC9000 is too low. It can run up to 15 engines at the same time, and the simulation degree is only 99.99%. There is still a certain error with the actual situation."

"So I still have a second option, which is to directly purchase a 'Supernova 1' supercomputer with a computing power of more than 1 billion billion operations. The computing speed is 15 times that of the TC9000, and a maximum of 200 units can be placed at a time. The engine equipped with 'Virtual Factory 2.0' has a simulation degree of more than 99.9999%, and the error is smaller."

"After you buy this supercomputer, you can use it however you want, and even develop two or more engines at the same time... You can arrange it freely."

Tan Ruisong's eyes lit up and he asked, "Then how much is it to buy your company's Super?"

"A billion."

Chen Jin said: "This price is definitely the price of cabbage. My dad specifically explained it. I don't earn any money from you, but only recover the cost of hardware and software development."

His father, Chen Gang, did tell him about this matter, and advised him to support the domestically-made large airliner project and reduce the cost of the project. In the future, many more C919s will be sold. This is also due to Chen Jin's contribution... After thinking about it, he agreed.

"I choose the second one!"

Tan Ruisong said without hesitation, it is indeed the price of cabbage! He has never heard of a supercomputer with a computing power of 1 billion billion operations, let alone a "virtual factory" technology whose value is much higher than that of the supercomputer itself.

That's it for the cooperation.

...

However.

Only one day has passed.

A group of soldiers in blue military uniforms came from Xinghai Technology Company.

The leader is Major General Pei, named Yuan Lang, tall and tough, and is the military procurement representative of Z Aviation Industry Group.

After receiving such a group of people, ask the other party why they came.

When Yuan Lang opened his mouth, Chen Jin was surprised: "Uh, we want to buy three 'Supernova 1', uh, all of them are equipped with virtual factories."

I wipe.

Chen Jin immediately wanted to scold his mother, Tan Ruisong, that fellow, it's okay to take advantage of it, but he actually betrayed me and summoned his friends to come over to take advantage of it.

Shangfa Company is a joint-stock company. Z Aviation Industry Group holds 40% of Shangfa's shares and is the largest shareholder of Shangfa Company. Tan Ruisong just signed the purchase contract with Xinghai Technology yesterday, and the military representative came over today.

Who told the secret is self-explanatory.

Seeing Yuan Lang's embarrassed and expectant expression, Chen Jin felt very helpless.

The third watch is really the limit, it is difficult to write an extra thousand words, the quality is extremely bad! Let's try our best to ensure the quality
