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

His class schedule has been readjusted and planned, and most unnecessary courses have been cancelled—of course, it is the cancellation of the assessment.

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

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

Chen Nian was not too impatient, because he knew very well that what he lacked most now was the training of basic knowledge and basic theory. It will be much simpler.

After class, he and Li Xiang went to the cafeteria to eat together, and happened to meet the girl whom he had met in the library before, and her brother was standing beside her.

During this period of time, the girl had been "stealing" Chen Nian's learning methods, and the two became a little familiar. Chen Nian knew her name, Qiao Mai, and her brother was Qiao He.

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

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

He was talking about Chen Nian's "business trip" to Fengtian 601. From his point of view, it was a somewhat special but reasonable tour of outstanding student representatives.

"Uh, it's alright, what's wrong with this, anyway, I was taken around to look around, and then played in Fengtian for a while."

"Ham, not all public tours are like this, there's nothing special about it."

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

"Did you see anything new?"

Li Xiang was slightly disappointed.

"Which round will I come to see the confidential things?"

Chen Nian sighed cooperatively, but he was telling the truth. In fact, during the time he went to Fengtian, including in Fengtian, his secrecy sequence had not been mentioned. Except for the No. 22 project, in fact, the 601 Let alone most of the area, he couldn't even get close to it.

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

"Then it's so simple. Last time, Mai Mai and I also went to the Beiji Electric Institute. Like Chen Nian, we went around randomly. The next day we arranged to see the flag raising, which was basically like traveling. almost."

Qiao He on the side interjected.

"Are you also a student representative visiting?"

Qiao Mai nodded and replied:

"Yes, I went with my brother, it doesn't mean much."

Looking at her dull expression, Chen Nian secretly sighed:

Although this matter is really not very interesting, it is actually a great honor for ordinary students of Xigong University.

That is to say, the two top students in front of me can take it so seriously.

But when Qiao He mentioned the Beiji Electric Institute, he suddenly remembered another thing:

Isn't there a superplastic forming machine at the North Research Institute?

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

Thinking of this, he casually asked:

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

In fact, he himself did not expect to get any useful information from the two brothers and sisters. He really wanted to analyze the superplastic forming machine in the future. The best way was to consult experts in related fields through Chen Guo.

In this way, the security is the highest and the information obtained is the most accurate.

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

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

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

Chen Nian didn't respond, but Li Xiang nodded, following Qiao Mai's words and asked:

"I know, many high-strength materials used in aircraft are superplasticized, like engine blades and the like."

"However, I have never seen a machine before, and we haven't learned that much. How about the machine? Is it easy to use?"

Qiao Mai on the opposite side sighed and replied:

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

"It can only be said that it is barely usable."

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

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

"Let's not talk about me, those brothers and sisters in the North Research Institute have been busy for five years, but they haven't made much progress."

"The imitation products are too poor, mainly due to the problems of high pressure and hydraulic modules, which leads to the failure of the yield rate."

Hearing this, Chen Nian's eyes lit up.

Sure enough, the same as the information I learned in my previous life, the core performance constraints of the superplastic forming machine are in these two modules.

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

"What exactly is the problem?"

Chen Nian asked curiously.

"Superplastic forming equipment does not have a heating module, but relies on energizing the material itself to heat up. In this process, the material is required to be able to rapidly heat up to more than 10,000 degrees Celsius, and at the same time, the temperature must be precisely controlled by the computer system."

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

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

——

Maybe not now, though.

What if you put the parsed target on the capacitor?

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

Only 0.1 source points are needed!

Doesn't this save another 0.1?

Comfortable!

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

"Except for this? What is the main problem with the hydraulic module?"

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

"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."

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

You can't solve it, but I can!

Chen Nian thought to himself.

He couldn't wait to continue asking:

"Then how can you slow down?"

"The current direction is the spherical articulated structure and the parallel linkage beam ultra-low-speed hydraulic system, but these two directions are very difficult. My postgraduate project is going to be a parallel linkage beam. I hope I can achieve results by then."

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

The result made him extremely gratified.

It only takes 0.06 source points to add up.

Good guy.

In this way, this meal directly saved him 0.24 source points!

Rounding it up, I have caught up with an F-22!

He secretly thought in his heart:

Senior sister Qiao, you are really a lucky charm.

However, there is a high probability that your graduate topic will be changed.
