Chapter 1105 One shot and two shots

After Chang Haonan nodded in agreement, everything that happened next really went very fast.

Just three days later, the Academy of Sciences and the Academy of Engineering respectively announced the list of candidates for the second round of election of academicians in 2003.

In this era, although both academies have established their own official websites, out of habit, they will still first make their information public to the society through paper media, such as scientific 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 personally sent by Zhu Linyu.

twice.

"Boss 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 start.

It would be a lie to say that Chang Haonan had never thought about the matter of having two academicians.

However, considering the specific circumstances of the previous batch of dual academicians and his current age, he has always rationally believed that the possibility is not great.

The result was a complete surprise.

"There's nothing I can do... You're the only one, and everyone wants to take advantage of you, so this is the only way left..."

Zhu Linyu, who was sitting opposite, revealed a hint of helplessness in his tone, but there was a barely detectable cunning glimpse in his eyes.

Chang Haonan noticed this, looked down carefully, and indeed found a clue -

The work units shown on the two tables are not the same.

One is Beijing University of Aeronautics and Astronautics.

The other is the Aviation Power Group.

Chang Haonan understood instantly.

This is not the case that “everyone” wants to take advantage of it.

It's obvious that the other party is trying to take advantage of the situation.

However, the Aviation Power Group is his old company after all, so he would not expose it in public.

After some joking, Zhu Linyu was the first to calm down and get down to business:

"Comrade Haonan, it would be best if you could stay in Beijing for a while."

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

"How to say?"

"Because there were many problems in the past when only written materials were used for selection, starting this year, some departments of the two academies may conduct a pilot to invite candidates to make on-site work reports and defense."

Zhu Linyu explained:

"Although the materials I submitted to you are very convincing, it is after all... a special situation, so there is no guarantee that we won't find you, so it's best to prepare."

"Do not worry."

Chang Haonan nodded:

"The work in Gaojing has been basically sorted out. In the next few months, I should be preparing a few new projects in Beijing."

Zhu Linyu's eyes suddenly widened:

“Any new projects?”

For him, Chang Haonan's answer just now was mixed with joy and sorrow.

Chang Haonan's title of academician is almost certain to be secured. Having new ideas at this critical juncture will help him strike while the iron is hot and leverage more resources, which is naturally a good thing.

But on the other hand, the Aviation 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, without enough people to do research, it will all be in vain.

At the moment, supporting the development of two new models (AE1500 and QC300) and the improvement of several other existing models is basically the end of the road.

If there is really one more big job, I will probably face the dilemma of having the will but not the strength.

"Don't worry... we're not going to make a new model."

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

"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 plan to use the experience of Torch-CB Ferrari to solve it in advance."

"In addition, there are some longer-term considerations. Under the current conditions, we can only do some preliminary research..."

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

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

Including Chang Haonan, three people from Aviation Power Group entered the second round of selection for academicians this year.

The other two are naturally Yan Zhongcheng and Jiang Fuhe, who returned empty-handed in 2001.

But objectively speaking, neither is too stable.

Moreover, given their age, even if they are successfully evaluated, it is unlikely that they will be able to personally participate in the research and development front line.

Therefore, the degree of importance attached to the group level is naturally different.

But Chang Haonan was quite calm about this:

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

"As for the preliminary research... at least at this stage, we can just leave it to the Torch Laboratory."

The first two students taught by Chang Haonan personally have now graduated.

Wang Jie naturally stayed at the school to teach, and although Li Yabo was still in the postdoctoral stage, he only had one year left before graduation.

The three lecturers at that time also gradually became associate professors and obtained the qualifications of doctoral supervisors.

The scale and research capabilities of the entire research team have naturally increased a lot, and they can conduct some independent research away from Chang Haonan.

……

Unsurprisingly, the second round of candidate information released by the two houses sparked some controversy.

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

But being on both lists still surprised many people.

After all, there are limited places for selection each year, and you take up two of them, which will inevitably affect the chances of other candidates.

It was not until the end of October that Station C's evening news devoted about three minutes to a special report on the 10 academician selection.

It is particularly 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 made 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 was quickly settled.

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

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

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

The actual R&D tasks are undertaken by Torch Laboratory and CB Ferrari.

As part of the project preparation phase, after returning to Beijing at the end of October, Chang Haonan quickly contacted Yang Weihua, the R&D director of Torch-CB Ferrari in China, and Wei Yongming, who had been responsible for the R&D 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 review..."

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

"Actually, you're right."

Chang Haonan said with a smile as he sorted out the things he had just taken out of his briefcase:

"I have indeed been preparing for the second round of review recently."

"what?"

Wei Yongming originally just wanted to make a joke and find an angle to compliment.

But I never expected to get such an answer:

"Then today..."

Chang Haonan tapped the documents on the table lightly:

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

"..."

Faced with his boss who was pretending to be powerful without being seen, Wei Yongming froze in his seat for a moment, and finally could only respond with an expression of admiration.

Yang Weihua, who had been silent just now, was also relaxed a lot by this conversation.

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

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

Chang Haonan didn't even look down. He flipped through the documents in front of him and turned to the page marked "Cutting Error Modeling". Then he continued:

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

"..."

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

The other two were also experts and were familiar with the problems existing in semi-automated processing, so they quickly understood what the former meant.

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

After a moment's 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 fully determine the deformation between the semi-finished product and the original design during the processing without human participation... Director Wei should understand this in more detail."

Wei Yongming, who was suddenly called, 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 surface as the positioning reference, and then use a three-coordinate measuring machine for measurement. This is indeed feasible for products with relatively regular shapes, but if the surface geometric contours of the processed object are not clear enough, then 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 determine the similarity between products and designs... However, this requires unimaginable computing power support, at least the current level of computer hardware cannot achieve it..."

"..."

Although the feedback he received was about the obstacles he was currently facing, Chang Haonan was generally pleased.

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

Although Wei Yongming and Yang Weihua were unable to come up with a solution for this new project, they were able to raise very specific technical issues.

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."

Chang Haonan already had an idea of ​​the current research progress, so he immediately said:

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

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

As Chang Haonan spoke, he took out two more documents from his briefcase and handed them to the two of them:

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

This creative idea made the other two people a little confused.

At first glance, it seems really simple.

Integrating the tool error over time will naturally reflect the error in the machining result.

But that is in one dimension.

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

Also consider the fixture, eccentricity, deformation, radial runout...

Let alone analyzing it, just thinking about it makes my scalp tingle...
