Virtual Factory!

Make the impossible possible.

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

The words of the father and son, He Jinlong immediately believed seven or eight points.

After all, the breakthrough of Zhongxin International is simply an industrial myth, and many people still think that this is not true, but a shocking scam...... There are many related exposés on the Internet, such as Fang Zhouzi, a famous anti-counterfeiting fighter, who wrote a "Ten Questions about Zhongxin's 7nm Chip", which had a great impact and even caused Zhongxin's stock price to plummet.

He Jinlong read the article, and after reading it, his heart was also full of doubts.

But now, his doubts were dispelled and the best answer was obtained.

The magic of virtual factory technology has the potential to create an industrial myth!

"Mr. He, the virtual factory technology cannot be announced to the public yet, I hope you can help keep it secret, this technology still can't be known by too many people."

Chen Jin admonished.

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

……

The next day.

Commercial Aircraft Engines Company.

Tan Ruisong, chairman of the board of directors of the 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 phone call from Mr. He of the commercial aviation company yesterday.

"How is that possible?"

After hearing about the virtual factory technology, his first reaction was also shock and disbelief: "How can computer simulation technology be so powerful?" ”

He Jinlong had to explain, and also gave 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!" ”

……

Since the headquarters of Shangfa Company is also in Shanghai.

Morning.

Tan Ruisong came downstairs to the headquarters of Xinghai Technology.

waited for nearly two hours before seeing Chen Jin.

Inside the conference 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 simulated physical research and development?" ”

Chen Jin shook his head: "Hearing is false, seeing is believing, in this way, I will take a TC9000 computer for you to try, which is equipped with 'virtual factory 1.0' technology, you send a group of engineers to come over, assemble an engine in the virtual factory, and directly see if the simulation environment is big or not." ”

"Good!"

Afternoon.

A technical team composed of hundreds of engine experts sent by Shangfa Company entered the fourth R&D plant of Xinghai Technology.

Due to the small size of the engine.

In addition, the CAD industrial design drawings can be imported into the virtual factory to directly generate the engine, and the expert team assembled an engine in only a few hours.

That same evening.

They got the first batch of valuable data.

"It works, it really works!"

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

"Increase the fuel supply, and the thrust will be increased to about 148KN...... Hey, it actually happened, and there was also a problem of engine interval surge here, which shows that our engine does have obvious design flaws. ”

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

About ten hours later.

"Boom~!"

In the virtual factory, the engine with too high internal temperature exploded into a pile of debris.

An expert who stared at the experimental data and barely slept all night said: "Almost, all the experimental results are similar to the real situation." ”

So......

Everyone looked at each other for a moment, and then couldn't hide their joy and excitement.

Some even couldn't hold back their tears.

"Over the years, we have been scolded too much and received too much criticism."

"It's not that we don't do it, the 1.5 billion yuan per year given by the above 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 will have to continue to improve, and it will take at least five years to catch up...... But we caught up, and better and more advanced engines in the West were launched, and the result was that they could never catch up. ”

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

"Artifact, this is really an artifact!"

Not bad.

Déjà vu.

The dilemma faced by the Z civil engine is almost exactly the same as the chip.

The exploration of advanced chip manufacturing process lies in constantly adjusting the production process...... It takes a lot of time.

The development of the engine requires burning a lot of money.

With a fund of more than one billion yuan a year, excluding some personnel expenses, it is only enough to produce more than a dozen verification machines and do more than 10,000 hours of testing, with an average test cost of about 100,000 yuan per hour.

This seems quite impressive, but with the current efficiency of Shangfa Company, the number of verification machines must be increased to more than 30, and the annual test hours must reach 30,000+, before it is possible to come up with the CJ-1000 with the same technical level as the LeapX engine by 20X5.

This means that the annual expenditure will have to increase to more than 3 billion.

However, although the industry of country Z is large, there are many places to spend, and it is impossible to have "unlimited funds" in terms of engine development.

However, with the virtual factory, the embarrassing situation of the business development company will be fundamentally improved immediately.

As long as the computing power of the supercomputer is large enough, in the virtual factory, 100 groups or 1,000 groups of test benches are placed, and each test bench has an engine, and experiments are carried out at the same time, and adjustments and optimizations are constantly made, and one is generated immediately when the engine is broken......

In this way, the development of the engine saves money and time, which may be more exaggerated than the research and development of chips.

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

……

"Mr. Chen, how much? 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 options."

Chen Jin said: "The first one, renting a TC900 with less than 100 million times per second of computing power, I will charge a friendship price and give 100,000 yuan of electricity every day, this price should not be expensive, right?" ”

"Not expensive, not expensive!"

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

"However, the computing power of TC9000 is too low, and it can only run 15 engines at the same time, and the simulation degree is only 99.99%, which still has a certain error with reality."

"So I have a second option, that is, to directly buy a 'Supernova 1' supercomputer with a computing power of more than 1 billion times, the computing speed is fifteen times that of the TC9000, and more than 200 engines can be placed at a time, and the simulation degree of the 'virtual factory 2.0' is more than 99.9999%, and the error is smaller."

"After you buy it, you can use it as you want, and even develop two or three engines at the same time...... You are free to arrange. ”

Tan Ruisong's eyes lit up and asked, "Then how much does it cost to buy your company's supercomputer?" ”

"Billion."

Chen Jin said: "This price is definitely the price of cabbage, which my father specially explained, not to make your money, but to recover the hardware cost and software research and development cost." ”

Chen Gang, my father, did advise him to support the domestic large passenger aircraft project and reduce the cost of the project, so that the C919 will sell a lot more in the future...... After thinking about it, Chen Jin agreed.

"I'll pick the second one!"

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

The cooperation was reached.

……

However.

Only one day passed.

Xinghai Technology Co., Ltd., a group of soldiers wearing blue military uniforms came.

The leader is Pei with the rank of major general, named Yuan Lang, tall and tough, and is the military procurement representative of the Z Aviation Industry Group.

After meeting such a group, ask the other party what they mean.

Yuan Lang surprised Chen Jin when he opened his mouth: "Well, we want to buy three 'Supernova No. 1', well, all equipped with virtual factories." ”

I rub.

Chen Jinden wanted to scold his mother, Tan Ruisong, that guy, even if he took advantage, he actually betrayed me and summoned his friends to come over and take advantage of it.

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

It is self-evident who tells the secret.

Looking at Yuan Lang's cramped and expectant expression, Chen Jin was very helpless.
