Chapter 1105: Double Strike

After Chang Haonan nodded in agreement, everything that happened next moved very quickly.

Just three days later, the Academy of Sciences and the Academy of Engineering announced the candidates for the second round of the 2003 academician election.

In this era, although both houses have established their own official websites, out of habit, they will first disclose their information to the public through print media, such as science news.

Therefore, it was not until Chang Haonan returned to Beijing and returned to the Aviation Power Group that he saw his name in the two documents sent by Zhu Linyu personally——

twice.

"Mr. Zhu, this..."

He pointed at the two forms in front of him with a look of astonishment, and for a moment he didn't even know how to speak.

It would be a lie to say that Chang Haonan has not thought about the double academicianship.

However, considering the specific situation of the previous batch of double academicians and his current age, he has always thought that the possibility is unlikely.

The result was a complete surprise.

"There is no other way... You only have one person, and everyone wants to take advantage of it, so this is the only way left..."

Zhu Linyu, who was sitting opposite, sounded a little helpless in his tone, but there was a trace of undetectable cunning in his eyes.

Chang Haonan noticed this, lowered his head and took a closer look, and found a clue——

The work units displayed on the two tables are different.

One is Beijing University of Aeronautics and Astronautics.

The other one is the Aviation Power Group.

Chang Haonan realized it instantly.

How can "everyone" want to take advantage of this?

It's obvious that the other party wants to take advantage of it.

However, the Aerospace Power Group belongs to the original family after all, so he would not expose it in public.

After some joking, Zhu Linyu took the lead in calming down his expression and got down to business:

"Comrade Haonan, it is best for you to stay in the capital for a while during the next period of time."

Although Chang Haonan had this intention, he was still a little surprised when he heard the other party specifically made this request:

"How to say?"

"Because there were many problems with selection based on written materials in the past, starting from this year, some departments of the two colleges may conduct a pilot program to invite candidates to conduct on-site work reports and defenses."

Zhu Linyu explained:

"Although the materials reported to you are already very convincing, after all... it is a special situation, so there is no guarantee that we will not find you, so it is best to be prepared."

"Don't worry."

Chang Haonan nodded:

"The work in Haojing has been basically straightened out. In the next few months, I should prepare several new projects in the capital."

Zhu Linyu's eyes suddenly widened:

"Any new projects?"

For him, Chang Haonan's answer just now was a mixed blessing -

Chang Haonan's academician title is already guaranteed. It is naturally a good thing to have new ideas at this juncture, which will help to strike while the iron is hot and leverage more resources.

But on the other hand, the Aerospace Power Group has only been established for a few years, and its research and development capabilities are still limited.

No matter how many resources there are, if there are not enough people to carry out research, it will only be in vain.

At present, supporting the research and development of two new models (AE1500, QC300) and the improvement of several other existing models at the same time is basically the end.

If we really have another big job, I'm afraid we will have to face the dilemma of having more than enough ambition but not enough energy.

"Don't worry...it's not about making a new model."

Seeing Zhu Linyu's twisted expression, Chang Haonan roughly guessed what the other person was thinking, so he smiled and comforted:

"In terms of the production of AE1500, we still need some new technologies that have been less studied in the past, or even completely blank... I am going to use the experience of Torch-C.B. Ferrari to solve it in advance."

"The other thing is some longer-term considerations. With the current conditions, we can only do some preliminary research..."

Zhu Linyu also relaxed after hearing this and quickly expressed his stance:

"In short, if there is any need for support, the group level will definitely do its best to meet your requirements!"

Counting Chang Haonan, three people from the Aviation Power Group entered the second round of academician selection this year.

The other two are naturally Yan Zhongcheng and Jiang Fuhe who returned home in 2001.

But objectively speaking, they are not very stable.

And given their age, even if they are successfully awarded, they are unlikely to be on the front line of research and development again.

Therefore, the level of emphasis at the group level is naturally different.

But Chang Haonan is very normal about this:

"It's not necessary...for adaptive processing, Torch Group itself has a certain research and development foundation, and it can also get support from the Seiko Project."

"As for those preliminary research... at least for now, just leave it to the Torch Laboratory."

The first two students brought out by Chang Haonan have now graduated.

Wang Jie naturally stayed at the school to teach, while Li Yabo, although still in the postdoctoral stage, had only one year left before leaving the university.

The three lecturers at that time also became associate professors one after another and obtained doctoral supervisor qualifications.

The scale and research capabilities of the entire research group have naturally become much larger, and they can conduct some independent research without Chang Haonan.

…

The second-round candidate information announced by both houses of Congress has predictably triggered some controversy.

No one dared to question Chang Haonan's qualifications for election.

But being on both lists at the same time still surprised many people.

After all, the number of candidates is limited each year, and if you take up two, it will inevitably affect the chances of other candidates.

It was not until the end of October that a C station evening news report on the 2003 academician selection took about 3 minutes.

It was specifically mentioned that in order to ensure the authority of the Department of Engineering Management, some academicians or academician candidates of the Academy of Sciences who have achieved widely recognized achievements in engineering project practice will be allowed to join the department.

Such a statement naturally represents the official attitude.

Therefore, the open debate quickly subsided.

But the pressure on the Academy of Engineering will not completely disappear...

However, the rumors from the outside world did not affect Chang Haonan's work plan.

After the National Day holiday, he submitted a project called "Thin-walled Complex Workpiece Processing Modeling and Online Compensation Research" to his superiors. The main investors were the Seiko Project Fund Committee, the Aviation Power Group, and the Aerospace Science and Technology Group.

The actual R&D tasks were undertaken by the Torch Laboratory and C.B. Ferrari Company.

As part of the project preparation phase, Chang Haonan also returned to Beijing at the end of October and quickly found Yang Weihua, the R&D director of Torch-C.B. Ferrari in China, and Wei Yongming, who has been responsible for the development and maintenance of digital industrial control systems.

The two are also the highest-level technicians in the field of mechanical processing in the entire Torch Group system...

"To be honest, I thought you, Mr. Chang, should be busy preparing for the second round of reviews..."

Wei Yongming and Chang Haonan have known each other for a long time, so he didn't seem so nervous in front of the latter.

"Actually, you are right."

Chang Haonan smiled as he sorted out the things he had just taken out of his briefcase:

"I am indeed preparing for the second round of reviews recently."

"Ah?"

Wei Yongming was just thinking of making a joke and finding an angle to compliment him.

But he never expected to get such an answer:

"Then today..."

Chang Haonan tapped the information on the table gently:

"For me, doing the project well is the best preparation for the second round of review."

"..."

Faced with his boss who was pretending to be powerful, Wei Yongming froze in his seat for a while, and finally had to respond with an expression of admiration.

Yang Weihua, who had not spoken just now, was also relaxed a lot by the exchange in front of him.

So, the three of them quickly got to the main topic of today's discussion.

"I think you two should have read the research background and implementation requirements of this new project."

Chang Haonan didn't even look down, and flipped the information in front of him to the page marked "Cutting Error Modeling", and then continued:

"In general, as my country's industrial production capacity continues to develop towards high-end, it is necessary to eliminate... or at least reduce the dependence on manual operation steps in the processing of complex parts..."

"..."

Chang Haonan spent about ten minutes to simply introduce the problems faced in the processing of AE1500 fan blades and the basic ideas of adaptive processing.

The other two were also experts, and they were familiar with the problems in semi-automatic processing, so they quickly understood the former's meaning.

However, they did not seem very optimistic about the project itself.

After a moment of silence, Yang Weihua spoke first:

"In recent years, we have also cooperated with the Italian side to conduct technical research on intelligent processing, but it is still difficult to completely determine the deformation between the semi-finished product and the original design during the processing without human participation... Director Wei should understand this more carefully."

Wei Yongming, who was suddenly cueed, also nodded:

"Mr. Chang, you just mentioned in-situ detection... The current mainstream technical route is to use the key feature points of the workpiece's surface as the positioning reference, and then use a three-coordinate measuring instrument for measurement. It is indeed feasible for products with relatively regular shapes, but if the surface of the processing object is If the geometric contour is not clear enough, the accuracy of the simple digital measurement method is not optimistic..."

"In addition, I have also tried to improve the image comparison algorithm you developed before, using multi-dimensional views to judge the similarity between products and designs... But this requires unimaginable computing power support, at least the current computer hardware level cannot achieve it..."

"..."

Although the feedback received is the current obstacles, Chang Haonan is generally quite gratified-

Torch-C.B. Ferrari is not satisfied with its absolute advantage in the domestic market, but insists on conducting cutting-edge research in the field of mechanical processing.

Facing this new project, Wei Yongming and Yang Weihua, although they failed to come up with a solution, can raise very specific technical issues.

And those who often do scientific research must know that being able to refine the problem basically means that half of the success is already achieved...

"Contact measurement is a universal problem in adaptive processing, so we can discuss it later for the time being."

For the current research progress, Chang Haonan already has an idea in his mind, so he immediately said:

"But when it comes to adaptive cutting processing, there is actually a more opportunistic way..."

"It is indeed difficult to obtain the deformation of the workpiece directly, but the error of the workpiece comes from the tool, and the runout and deformation of the tool during the processing are relatively easy to measure."

While speaking, Chang Haonan took out two other documents from his briefcase and handed them to the two people respectively:

"In this case, we can establish a thin-walled comprehensive dimensional error model, and then iteratively calculate the comprehensive dimensional error to directly obtain the required compensation amount, thereby achieving effective compensation for the thin-walled dimensional error..."

This brain-opening idea made the other two people a little confused.

At first glance, it seems to be very simple.

Integrating the tool error over time is naturally the error reflected in the processing result.

But that is in one-dimensional space.

In actual cutting processing, the tool itself has at least three degrees of freedom.

It is also necessary to consider the fixture, eccentricity, deformation, radial runout...

Don't even mention the hands-on analysis, just thinking about it makes people's scalp numb...
