Chapter 40 An unexpected gain

After completing the study of the confidentiality regulations, it was just 12 noon. After lunch, Chen Nian came to the classroom as planned.

His class schedule has been readjusted and most unnecessary courses have been cancelled--of course, assessments have been cancelled.

In the eyes of other students, he just skipped a lot of classes.

Two sections of high numbers and two sections of big things provided him with some relatively basic knowledge and produced 0.01 source points. Compared with the number of source points required by the F119 engine, it was a drop in the bucket, but it was better than nothing.

Chen Nian is not too impatient, because he knows very well that what he lacks most now is basic knowledge and basic theoretical training. Once this part is done, he can learn other specialized subjects to brush up his source points later.

It will be much simpler.

After class, he and Li Xiang went to the cafeteria to eat together, and happened to meet two brothers, Qiu Mai and Qiao He, so the four of them sat together.

After putting down the plate, Li Xiang couldn't wait to ask:

"Hey, Chen Nian, how's it going? Did it go well for you there? Did you get any unexpected gains?"

What he was talking about was Chen Nian's "business trip" to Fengtian 601 Institute. From his perspective, it was a somewhat special but reasonable visit for outstanding student representatives.

"Well, it's okay. How can this go smoothly? Anyway, I was taken around to look around and then played in Fengtian for a long time."

"It's bad, not all public-funded tours are like this, it's nothing special."

But unexpectedly, Qiu Mai's answer was far beyond his expectation.

"Hey, those of you who build airplanes must have heard of superplastic forming, right?"

"The current directions are spherical articulated joint structures and parallel-linked beam ultra-low-speed hydraulic systems, but these two directions are very difficult. My graduate project is going to be about parallel-linked beams. I hope I can achieve results by then."

"But I've never seen a machine before, and we haven't learned that much - how about the machine? Is it easy to use?"

Thinking of this, he asked smoothly:

"This is not a problem that we can solve in a short time."

"Are you also a student representative visiting?"

"I can only say that it is barely usable."

If this is the case, then you are on the right track.

Only 0.1 source points are needed!

Doesn’t this save another 0.1?

Comfortable!

Hearing this, Chen Nian's eyes lit up.

The result made him extremely happy.

Chen Nian nodded slightly. In fact, this problem has not been solved even ten years later. We still have to rely on imports for most ultra-high power capacitors.

——

However, it may not be necessary now.

He couldn't wait to continue asking:

Chen Nian asked pretending to be curious.

"The copied products are too poor, mainly due to problems with the high pressure and hydraulic modules, which results in a failure to improve the yield rate."

"Therefore, the performance of high-voltage modules is extremely important. Our main difficulty lies in high-power capacitors. We are too weak in this area."

"Superplastic forming equipment does not have a heating module. It relies on energizing the material itself to heat it. In this process, the material is required to be quickly heated to more than 10,000 degrees Celsius, and at the same time, the temperature must be accurately controlled through the computer system."

He closed the system interface with satisfaction, and then continued to ask:

"Then how can we slow down the speed?"

You can't solve it, I can!

Chen Nian's answer was flawless, and this was also the caliber that had been designed long ago.

"This is very important. If the speed is not slow enough, the formed metal will generate a lot of internal stress and may even deform and rebound."

But when Qiao He mentioned the Beijing Institute of Mechanical and Electrical Engineering, he suddenly remembered something:

Isn’t there a superplastic forming machine at Beiyan Research Institute?

I don't know if they saw it or not.

This is the most secure and provides the most accurate information.

In other words, these two academic masters in front of me could not take it seriously.

Chen Nian sighed in agreement, but he was telling the truth. When he went to Fengtian, including the time he was in Fengtian, in fact, he had not raised the confidentiality sequence. Except for Project 22, in fact, 601 Institute

Not to mention seeing most of the area, he couldn't even get close.

"It's not that simple. Last time, Mai and I went to the Beijing Institute of Mechanical and Electrical Engineering. Like Chen Nian, we just walked around casually. The next day, we were arranged to watch a flag-raising ceremony. It was basically like traveling.

almost."

Sure enough, just like the information I learned in my previous life, the core performance constraints of the superplastic forming machine lie in these two modules.

Li Xiang was slightly disappointed.

"That's right. I thought I could get in touch with things that we usually can't get in touch with."

Chen Nian thought to himself.

"What did you see when you visited the Beijing Research Institute?"

Chen Nian did not respond, while Li Xiang nodded and followed Qiu Mai's words and asked:

"You know, many of the high-strength materials used in aircraft are superplastically formed, like engine blades and the like."

What if the target of analysis is placed on the capacitor?

Chen Nian quietly brought up the system panel and modified the analysis target. This time, the number of source points required for analysis has indeed dropped significantly!

"Actually, it's nothing. I looked at everything, and I focused on the GLEEBLE1500 - it's the superplastic forming machine."

"When will it be my turn to see confidential things?"

"I was thinking about doing the reverse engineering before, but later I found out that this is not something I can do at all."

"Don't talk about me. Those senior brothers and sisters from Beiyan Research Institute have been busy for five years, but in fact they haven't made much progress."

"Accuracy, the hydraulic movement speed of a superplastic forming machine must be as low as 0.01 mm, but the speed of our ordinary hydraulic press is generally between a few millimeters and tens of millimeters. If it is any lower, it will cause crawling jitter."

In fact, he didn't expect to get any useful information from the two brothers and sisters. If he really wanted to analyze the superplastic forming machine in the future, the best way would be to consult experts in related fields through Chen Guo.

"Besides this? What is the main problem with the hydraulic module?"

"Actually, the performance of GLEEBLE1500 is far behind the current international average level, but we have no choice but to use it."

"Didn't you see anything new?"

After hearing her answer, Chen Nian quickly checked the analysis results of these two technologies in the system.

"What exactly is the problem?"

Qiu Mai on the opposite side sighed and replied:

"It's easy to use. It's a product that is two or three generations behind."

Seeing her bored expression, Chen Nian secretly sighed:

Although this matter is indeed not very interesting, for ordinary students of NPU, it is actually a great honor.

Qiao He on the side interjected.

Qiu Mai nodded and replied:

"Yes, I went with my brother. It wasn't very interesting."

It only adds up to 0.06 source points.

Good guy.

After calculation, this meal directly saved him 0.24 source points!

Rounding it all off, it’s as close as one F-22!

He thought secretly in his heart:

Senior Sister Qiao, you are really a lucky charm.

However, there is a high probability that your graduate project will need to be changed.
Chapter completed!
