The military-industrial scientific research system of the academic master.

Chapter 716 Poaching

Although Chang Haonan said that he was just trying to attract new ideas, Lin Jingtang has been involved in process numerical calculations for many years and basically belongs to the type that can be solved with just one click.

Even if only based on the content of theoretical calculations on the current drawing board, this seemingly unremarkable new algorithm can greatly reduce the amount of calculations in the process of solving the velocity field, which happens to be the most time-consuming part of the entire calculation process. Relatively large portions.

It's a pity that Factory 112 has not sent over the specific process parameters, so the more specific calculation steps have not been started yet. For the time being, we can only test several classic volume incompressibility conditions from the perspective of theoretical model research. Universality under one problem.

"In addition, Mr. Chang, before the equipment is officially powered on and started, we need to separately test the working status of the hydraulic synchronous correction system..."

"The fatigue analysis and reliability detection system we are responsible for here is currently performing open-loop testing..."

"Stroke sensing measurement system of main working hydraulic cylinder..."

"..."

Under the command of Chang Haonan, the progress reports of each subsystem and the next work plan were summarized one by one.

And in his mind, a relatively accurate and complete timetable gradually formed...

This is completely opposite to what happened later.

"no!"

Yan Yongnian has been stationed in the factory about a year ago and has never left including this year's Spring Festival. Naturally, he is the most qualified to answer this question:
"In the beginning, our place shared the power supply network with the neighboring Tuan County. There were still many problems at that time. However, later, Jiangcheng local government designated our area as a new industrial zone and specially approved a special power supply line. And without being affected by urban power usage planning, voltage stability and the number of power outages have been greatly improved.”

"This type of power outage due to force majeure is acceptable as long as it does not occur frequently and affects production."

If we put it aside more than 20 years later, there would be almost no need to worry about such problems. However, in this era, we are still on the eve of a major upgrade of the power system. Although a power outage in an entire city cannot be said to be a daily occurrence, it can be regarded as a daily occurrence. happens sometimes.

"To sum up, most of the work items in the cold car state have been completed, and only a synchronous correction system needs to perform a separate open-loop test."

"The last unplanned power outage here was probably in February this year. Before the Chinese New Year, the power supply line from the substation was crushed by ice accumulation. It took about 2 hours to restore."

Many high-end residences even have their own diesel engines.

Chang Haonan nodded slightly:
“Since there is no problem with the power supply, we will tentatively schedule to carry out the first power-on test of the equipment on May 5th. If no problems are found in the self-inspection and external inspection, we will start to warm up the hydraulic equipment on May 13th. , officially enter the device startup process, are there any problems?”

Therefore, having a dedicated power line can basically avoid most power supply problems.

"How is the power supply in the new factory? Have there been any power outages or voltage instability during the construction process?"

At the turn of the century, if the power grid faced the risk of overload, it would generally give priority to ensuring industrial power.

"In view of the occasional lack of energy supply, we took this issue into consideration when designing. The safety locking system is in power-on release mode, so there is no need to worry too much."

Chang Haonan raised his head and shifted his gaze from the notebook in front of him to the responsible personnel on both sides of the conference table:

"Then this is the end of today's meeting, adjourn!"

……

However, for extremely large equipment such as die forging presses, and surrounded by a whole new factory area in Jiangzhong, the power consumption level after operation is quite terrifying. Relying on self-prepared emergency diesel generators is a drop in the bucket, so power must be guaranteed by the local area. Just keep doing it.

Several others answered in unison.

After the meeting, Chang Haonan found Yan Yongnian alone in the factory who was conducting routine inspections of the workshop.

For Chang Haonan, the die forging press is only one of two large-scale projects that are being carried out at the same time. But for the latter, it is a career that he has been fighting for most of his life and almost missed. Yes, so the level of care is higher than that of the chief designer Chang Haonan.

The two stood on the visual inspection table on the second floor of the workshop, watching workers not far away climbing up and down the frame, installing some auxiliary equipment that was finally in place, as well as decorations that did not perform actual functions. For example, there are four huge Chinese characters for "Jiangcheng Heavy Machinery".

For a treasure like the super-heavy die forging press, which has only a few units in the world, Yan Yongnian even suggested giving it a name similar to a warship, not to mention just listing the production company.

In the end, Chang Haonan rejected him because he was too middle-class.

"I didn't expect that in two years, we would be able to build a tall building from the ground up and build this equipment from scratch..."

Yan Yongnian pushed the brim of his helmet with the antenna of the walkie-talkie in his hand, and said to Chang Haonan who had just walked up next to him:

"It's a pity... Mr. Shen didn't get to see this day."

The design of this 7.5-ton die forging press, as well as a considerable part of the technology, are based on a 80-ton prestressed steel wire winding die forging press developed by Qinghua University in the late 6.8s.

Academician Shen Hong was the person in charge of that project at that time and was also Yan Yongnian’s teacher.

Chang Haonan also made a special trip to visit before the die forging press project was established.

In May 1998, Shen Hong passed away at the age of 5.

At that time, we were in the most critical stage of transforming the equipment from drawings to physical objects. Therefore, Yan Yongnian, who was too busy to do anything, did not even make it to attend the other party's funeral.

Looking at Yan Yongnian who was thinking about people after seeing things, Chang Haonan felt that the effect of simple words of comfort might be average.

Moreover, he really hopes that this legendary academician with a primary school education who has worked hard for China Machinery all his life can be remembered by more people, at least more practitioners:
"I propose that after this die forging press completes its first trial production, the remaining parts of the blanks can be used to erect a bust of Academician Shen in the Jiangcheng factory to commemorate the work he has done for this die forging press. efforts and contributions.”

Yan Yongnian suddenly turned his head to look at Chang Haonan, his eyes trembling.

After a while, he nodded:
"it is good."

Then the two of them walked off the examination table one after the other.

"Professor Yan."

After walking around the workshop for a few more times, Chang Haonan directly performed a show:
"I remember that you have several doctoral students who participated in the entire numerical calculation process of our project. Are any of them graduating this year?"

"There are two graduates this year."

Yan Yongnian replied almost without thinking, obviously not realizing the seriousness of the problem:
"Why do you ask this suddenly?"

Chang Haonan was not prepared to conceal his purpose:
"After I graduate this year, I plan to set up a laboratory of my own. Of course, it will be based on the model of school-enterprise cooperation between Beihang University and Torch Group. Now there is a shortage of manpower, especially graduate tutors."

"Hiss... If you don't tell me, I will almost forget that you haven't graduated yet..."

Now Yan Yongnian understood.

This is to poach him...

However, because of the foreshadowing just now, if he refuses now, it will seem too inappropriate.

So, after hesitating for a moment, Yan Yongnian nodded:

"After they go back, I'll ask them to submit their resumes to Beijing Airlines... Anyway, they have experience in this project, so it shouldn't be difficult to pass..."
