After completing the study of the confidentiality regulations, the time had just reached 12 noon, and after lunch, Chen Nian came to the classroom as planned.

His class schedule has been rescheduled, and most of the unnecessary classes have been cancelled---- of course, the cancellation of the assessment.

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

Two high numbers and two large objects provided him with some relatively basic knowledge, and he brushed out 0.01 source points, which is a drop in the bucket compared to the 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, and when this part was done, he would learn other specialized disciplines to brush the source point later, which would also be much simpler.

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

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

"Hey, Chen Nian, how is it, did you go over there smoothly? Are there any windfalls? ”

He was talking about Chen Nian's "business trip" to Fengtian 601 Institute, and from his point of view, it was a somewhat special, but also reasonable visit by outstanding student representatives.

"Uh...... It's okay, what's wrong with this, anyway, I was taken around to look around, and then I played in Mukden for a long time. ”

"Harm, not all publicly-funded tourism is like this, nothing special."

Chen Nian replied without leakage, which is also a caliber that has been designed a long time ago.

"Didn't see anything new?"

Li Xiang was slightly disappointed.

"Confidential stuff is going to be seen by me......."

Chen Nian sighed cooperatively, but what he said was also the truth, during the time he went to Fengtian, including in Fengtian, in fact, his secret sequence had not been mentioned, except for the No. 22 project, in fact, he couldn't even get close to the vast majority of the area of the 601 Institute.

"Oh, too...... I thought I would be able to touch something we wouldn't normally touch. ”

"Then where is it so simple, last time I went to the North Electromechanical Institute with Mai, the same as Chen Nian, they all went around casually, and the next day we were arranged to go to see the flag-raising, which is basically similar to tourism."

Qiao He on the side interjected.

"Are you also visiting as student representatives?"

Qiao Mai nodded and replied:

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

Looking at her boring expression, Chen Nian secretly sighed in his heart:

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

That is, the two scholars in front of him can be so inappropriate.

However, when he heard Qiao He mention the Beijing Electromechanical Institute, he suddenly remembered one more thing:

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

I don't know if they've seen it.

Thinking of this, he asked casually:

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

In fact, he didn't expect to get any useful information from these two siblings at all, and the best way to analyze the superplastic molding machine in the future is to consult experts in related fields through Chen Guo.

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

But unexpectedly, Qiao Mai's answer greatly exceeded his expectations.

"Actually, it's nothing, I've watched everything, and I focused on the GLEEBLE1500---- that is the superplastic molding machine."

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

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

"You know, a lot of the high-strength materials used in aircraft are superplastic, like some kind of engine blades and the like."

"But we really haven't seen a machine, and we haven't learned it that much---- so what about the machine? Is it easy to use? ”

Qiao Mai on the other side sighed and replied:

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

"I can only say that it can barely be used."

"In fact, the performance of GLEEBLE1500 is far behind the current international average, but there is no way, we can only use it."

"I was thinking about doing the reverse version, but it turned out that it wasn't something I could do at all."

"Don't talk about me, those senior brothers and sisters of the Beijing Research Institute have been busy for five years, but in fact, there hasn't been much progress."

"The imitation is too poor, mainly because of the problem of high pressure and hydraulic modules, which leads to the ....... of the finished product."

Hearing this, Chen Nian's eyes lit up.

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

If that's the case, then you're in the right direction.

"What's the problem?"

Chen Nian asked pretending to be curious.

"The superplastic forming machine does not have a heating module, and it relies on the electricity applied to the material itself to heat it. In this process, the material needs to be able to heat up quickly to more than 10,000 degrees Celsius, while at the same time being able to accurately control the temperature through a computer system. ”

"Therefore, the performance of the high-voltage module is extremely important, and our main difficulty is still in the high-power capacitor, which we are too weak in."

Chen Nian nodded slightly, in fact, this problem has not been solved even after ten years, and we still have to rely on imports for most of the ultra-high power capacitors.

----, though, maybe not now.

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

Chen Nian quietly called up the system panel and modified the parsing target, and this time, the number of source points required for parsing had indeed dropped significantly!

Only 0.1 source points are required!

Doesn't that save 0.1 again?

Comfortable!

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

"What about other than this? What is the main problem with the hydraulic module? ”

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

"It's important to note that if it's not slow enough, the formed metal will have a lot of internal stresses and even the possibility of deformation and rebound."

"It's not something we can solve anytime soon......"

You can't solve it, I can!

Chen Nian said secretly in his heart.

He couldn't wait to continue asking:

"How can you slow it down?"

"The current direction is the spherical hinged joint structure and the ultra-low speed hydraulic system of the parallel linkage beam, but the difficulty of these two directions is very great, and my graduate project is going to engage in the parallel linkage beam, I hope to have results by then......

Hearing her answer, Chen Nian quickly inquired about the analysis results of these two technologies in the system.

The results made him extremely happy.

It adds up to 0.06 source points.

Boy.

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

Rounding off, it's all time to catch up with an F-22!

He thought to himself:

Senior Sister Qiao, you are really a lucky charm.

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