Chapter 297 The Seiko Plan is gradually developing, the third generation aviation

Guiding three YSU students on the International Evolutionary Algorithm Competition, Chang Haonan initially thought it was just an interlude.

It was not until the day of the unveiling ceremony that Du Yishan took two academicians, Yang Fuqing and Wang Yangyuan, and introduced Chang Haonan to them, that the latter realized that this incident might have a deeper impact.

To outsiders, Academician Yang may be more famous for founding a company called Beida Jade Bird.

But for those in the know it’s a different story.

Due to special historical reasons, the achievements of many academicians in our country may not be particularly dazzling when viewed internationally.

In the late 60s, Yang Fuqing presided over the development of the operating system of the "150 machine", China's first million-time integrated circuit computer.

Wang Yangprin presided over the development of the computer's memory during the same period, which directly shortened the gap between domestic semiconductors and the world's leading level by almost 70 years in the mid-10s.

That’s 10 years in the semiconductor field!

Although the performance of the 150 machine is almost nothing to mention in the world, it is only one percent of the fastest computer computing speed at that time, but it is an important milestone in the development of electronic computers in our country. In a special period, it completed the work for the aerospace industry and The nuclear industry safeguards its mission.

It is no exaggeration to say that the simultaneous appearance of these two people directly increased the influence of Beijing Airlines' computing center to a level similar to that of the recently completed National High Performance Computing Center in Luzhou.

Of course, this is also a signal sent to the outside world——

The state encourages universities with the ability and resources to establish their own supercomputing centers.

Due to Chang Haonan's relatively special status, the scale of the ceremony was not large, and it was even held indoors.

But the specs are high.

Some well-known schools in the capital basically sent their leading experts and professors to participate.

Of course, Chang Haonan is still self-aware. Most of them should come here for Yang Fuqing and Wang Yangyuan, not for themselves.

But no matter what, the scene has already made enough money.

Although this is not the first time to participate in this kind of event, it is indeed the first time to be the protagonist, or to be the protagonist as a leader.

My heart is still a bit beat up.

Fortunately, the manuscript arranged for him was very considerate. The characters were written in very large words, some were error-prone or unfamiliar, and even pinyin was specially noted at the back.

As for the assembly language program that outputs hello world, it is the most stable.

The machine will not be nervous.

All in all, everything went well.

After the ceremony, there was a regular luncheon.

As Chang Haonan expected, after the two academicians chatted with him for a few words, they saw a huge flow of people approaching from a distance.

The former is still a little uncomfortable with this kind of scene, but the other two are obviously used to it.

Yang Fuqing took out a notebook from her jacket pocket, quickly wrote down a few numbers, then tore it off and handed it to Chang Haonan.

"This is Lao Wang and I's office, as well as our home phone number. If Xiao Chang needs any resources in the computer field in the future, we can try to help."

Chang Haonan quickly took it into his hands.

"Thank you, Academician Yang."

Now he is not as excited as when he first met Du Yishan this time last year, but being able to get someone's personal phone number is obviously a kind of recognition.

As for why the other party made such a high gesture, Chang Haonan was a little confused for the time being.

In short, it cannot be as simple as helping the three students recommended by Yang Fuqing two days ago.

The people present today were all adults. Even if they were present for the sake of two academicians, they would not be able to do something stupid like leaving Chang Haonan aside. Therefore, it took him almost ten minutes to finally accept the entire A round of congratulations.

Chang Haonan breathed a sigh of relief and squeezed out of the crowd, ready to take a rest and find something to eat.

One good thing about being a leader is that you only need to show up for such activities.

However, as soon as he put a piece of beef on the plate, another man who looked quite young appeared next to him.

"Hello, Chang Gong."

Chang Haonan turned his head helplessly, preparing to accept the other party's routine congratulations.

However, the other person’s next sentence was:

"My name is Wei Yongming. I am a graduate student majoring in precision instruments at Qinghua University. I would like to discuss with you topics related to process optimization and process control of metal thermal processing."

Although Chang Haonan had realized that he had indeed gained some fame in control theory, his first reaction was still surprise.

"Thermal processing of metals?"

This field is not something Chang Haonan has ever been involved in, and in my impression, Qinghua University is not good at metal material processing technology-related fields.

"Yes, this is part of a large project our school received from the 410 Factory this year, and it has been included in the key development targets of the Seiko Plan."

Chang Haonan understood after hearing this.

No wonder he found himself.

He still has the title of general consultant of Seiko Project, and he is waiting to become a full-time employee after graduation in two months.

You still have to listen to it.

After all, it is part of the job.

And he also wants to know to what extent the Seiko Project has developed in the past six months or so.

"Why don't we go eat and chat next to each other?"

Chang Haonan suggested while looking down at the meatloaf on the plate.

……

A few minutes later, the two people sat at an inconspicuous long table nearby.

"This project is mainly divided into two parts. One is to upgrade the previous EDM drilling equipment of the 410 factory to develop a micro-EDM CNC machine tool. The second is to develop a new investment mold for high-niobium titanium aluminum alloy materials. Precision casting process.”

"We have completed the EDM part relatively smoothly so far and have entered the prototype development stage. However, we have encountered some difficulties in the latter part because the investment casting process involves the effects of force, heat, and electricity at the same time, and the materials The performance and crystal phase are inherently affected by the elemental composition, and there are too many independent variables. We have almost exhausted all the methods we can think of, and still cannot simulate the entire continuous or even semi-continuous casting process well. "

After Wei Yongming introduced the situation, Chang Haonan immediately understood what Factory 410 was going to do.

Due to the successful completion of the Turbojet 14 plan, they are upgrading equipment and preparing to produce third-generation turbofan engines!

Not to mention the electric discharge machining system, the temperature in front of the turbine will increase to 1200c in the third generation, requiring more complex active cooling technology. In addition to being more difficult in design, it is also a huge challenge for processing.

The high-niobium titanium aluminum alloy mentioned in the second item has become one of the indispensable materials for advanced aerospace engines due to its advantages of high melting point, high strength, high modulus and low density.

In other words, after ten years of iteration, Turbofan 10 has finally taken its first real step.

This is a small step for the 410 Factory, but a big step for China's aviation power industry.
