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

No matter what Li Yabo thought, the members of the defense review panel had been decided.

That is, after Chang Haonan graduated last year, Du Yishan officially retired to enjoy his old age, otherwise there would have to be another one...

"teacher……"

After Tang Lintian left, Li Yabo, who was numb, came to Chang Haonan with a lingering fear on his face:

"I'm just a college graduate, this is too..."

"Don't worry too much, just prepare normally."

Chang Haonan was looking down at Li Yabo's paper at this time, and answered without raising his head:

"The content of your paper is enough to get you a master's degree. No matter who comes, they can't make things difficult for you."

Whether you are an undergraduate or a master's or doctoral student, the key to whether your graduation project passes is still the blind review.

There is no problem with the blind review, so as long as your defense process is not too outrageous, you won’t be blocked from graduation.

At most it would just be a little ugly on stage.

Of course, that's what it says.

As the person involved, Li Yabo must be nervous.

Especially since he plans to continue his studies after graduation, he must get a good evaluation for his thesis.

"Li Zi, why is your face so pale?"

After returning to the dormitory, a roommate quickly discovered that something was wrong with Li Yabo.

"I have to defend my thesis. I'm nervous."

The latter was lying on the bed, looking absent-minded.

"Oh my god...are you still nervous?"

Another roommate joked in an exaggerated tone:

"Didn't your boss just come up with a groundbreaking result?"

"That's right. Even if the judges are considering him, they won't make things difficult for you, right?"

"Besides, aren't undergraduate theses just something you do casually and just go through the motions?"

Several people chatted with each other, and the topic gradually shifted from Li Yabo's tutor to their respective graduation projects.

Even their own future.

"Ugh……"

Li Yabo, lying on the bed, sighed.

Obviously, his roommates didn't know what kind of devilish lineup they would face...

"Anyway, for the rest of you... especially Lao Bai and Fatty Wu who are going to graduate school... I still suggest that you prepare well..."

Soon, the day of the defense arrived.

The defense for undergraduates is different from that for postgraduates. Students from a college are divided into several groups, and each group corresponds to the same group of defense teachers.

The whole process basically lasts from morning to afternoon.

So, as one of the judges, Chang Haonan got up very early that day and arrived at school about an hour early.

However, there were still quite a few people standing in the corridor.

After all, June is the peak period for graduate student defense, not just for undergraduates.

Among the crowd, Chang Haonan happened to meet a familiar face.

Zhou Shuwan.

At this time, the other party also noticed him.

"Nan...Chang...Professor Chang, what are you doing..."

The moment he saw Chang Haonan, the most terrifying possibility flashed through Zhou Shuwan's mind -

My former classmates are going to be my defense judges...

"Oh, I'm here to see how the undergraduates are doing with their defense."

Zhou Shuwan breathed a sigh of relief.

However, Chang Haonan asked again.

"What about you? I remember your research group's laboratory is not here, right?"

"I……"

Zhou Shuwan's eyes darkened, and his expression suddenly became tense:

"Of course I'm here to defend my graduation thesis..."

"..."

Chang Haonan swore that he had indeed forgotten.

Three years after graduating from undergraduate studies, according to the normal schedule, wouldn’t it be the graduation defense for a master’s degree?

This is really a bit embarrassing.

"So...will you continue to study for a doctorate?"

He quickly changed the subject.

“Definitely.”

Zhou Shuwan also knew that Chang Haonan couldn't have done it on purpose, so he adjusted his mindset a little and nodded:

"In the field of aviation life-saving equipment, our country has rarely conducted systematic research before. It has only gradually developed after the introduction of the KD36D ejection seat with Project in the past two years. This is when manpower is needed."

The J-11 series fighter jets use the HTY36, which is 100% restored according to the K8D drawings, and its performance is naturally the same as the former, the best in the world.

However, the ejection seat needs to be adapted to the aircraft, so it is not possible to directly move the HTY8 to other domestic aircraft.

Tactical aircraft are easier to deal with.

The HTY10 equipped with the J-5 is slightly inferior to the HTY8 in terms of maximum ejection speed, but it is at least a standard third-generation ejection seat.

However, for large aircraft, such as the H-6, the situation is not so optimistic.

It even maintains the "glorious tradition" of crew members ejecting downwards.

So as Zhou Shuwan said, there is still a long way to go in this regard.

Just as the two were about to end their chat, a voice suddenly came from behind Chang Haonan.

It sounds somewhat familiar.

"Mr. Chang."

Chang Haonan turned around.

It was discovered to be Liu Gaozhuo.

The commander-in-chief of Project No. 11.

Although his contact with Chang Haonan was not as much as that with He Ming, who was in charge of production, they were old acquaintances.

"You were also invited here... to be a judge for the defense?"

According to regulations, the graduate student's defense committee must include members from other units.

Just like when Chang Haonan defended his doctoral thesis, he invited Yuan Xiangya and Qian Lao.

"I'm here mainly for the meeting and to be a judge."

As he was talking, Liu Gaozhuo also noticed Zhou Shuwan who was standing opposite Chang Haonan:

"Hey, it seems like he is here to be the judge..."

Then he turned his attention to Chang Haonan:

"you……"

"Classmate, it's a classmate..."

"..."

After some explanation, Liu Gaozhuo finally understood the rather complicated relationship between the two.

"By the way, Mr. Chang, there is something I want to talk to you about in private after the defense is over."

Before walking into the conference room opposite, Liu Gaozhuo leaned close to Chang Haonan and whispered.

The latter was stunned, then nodded:

"can."

"But it may take me a little longer. You can meet me at the computing center at four o'clock this afternoon."

……

Li Yabo's defense process was smooth sailing.

There was no situation where Chang Haonan argued with the scholars for him——

If he couldn't even handle such a small situation, Chang Haonan would never have recruited him in the first place.

However, this has made life difficult for the other people in Li Yabo's group.

Especially two of them who are also preparing for further studies.

Normally, when encountering more acute issues, the teacher would dare to step forward and offer a few words.

And now this scene...

Three academicians, one president, and Chang Haonan.

To sum it up, this is——

He only answers questions but does not argue. Once asked, he apologizes like crazy...

Of course, they were all given in the end.

after all……

A graduate from a university in Kazakhstan is not a human being at all.

Moreover, no matter how much the students of Beijing Aviation University slack off, there is still a bottom line, and no situation that would cause public outrage will occur.

After the entire defense process was over, Chang Haonan first asked Tang Lintian to send Wang Yuanguang and Huang Yunbo to the Torch Group's small canteen, while he returned to the office alone.

Liu Gaozhuo was waiting there as promised.

"Mr. Liu, what you said during the day was..."

The two of them sat down on two sofas respectively, and Chang Haonan asked straight to the point.

"Boss Chang, this is it."

Liu Gaozhuo explained:

"According to the needs of the Air Force and in light of the progress of the Project 6 improvement project, we are preparing to deliver six J-11B fighter jets from the trial production batch to the Air Force for small-scale leading use."

"That's a good thing, then."

Chang Haonan filled the other person's glass of water:

"Whether it's the aircraft itself or our power, if the Air Force is willing to accept a small batch trial, the progress will be much faster."

Liu Gaozhuo held the cup in one hand and used the other hand to tidy up his hair awkwardly:

"The main reason is... our factory wants to deliver this batch of aircraft before the end of this year, but the comrades over at Liming said that before December, they can only provide a maximum of 12 WS-10A engines. You see..."

Chang Haonan understood.

This is to ask for production capacity.

Because Project No. 10 and Project No. are being promoted at the same time, and both sides require the WS- as power, the already low production capacity has become even more stretched.

Especially after 2000, the J-10A produced two new single-seat 03 and 04 aircraft, as well as a two-seat 05 prototype in one go. When the backup was taken into account, the demand for the WS-10B increased immediately.

The production capacity allocated to Model A will naturally decrease.

"Ugh……"

After thinking for a while, Chang Haonan sighed and answered:

"Mr. Liu, let me tell you directly that in the second half of the year, the total production of WS-10 will be 10 at most. Three prototypes are being built for Project 3, which means 1 engines. One backup engine must be kept, so the production capacity of these 6 WS-10A engines has indeed reached its limit."

"We are all brothers in arms. I can't possibly cut off their supply to Project No. 10..."

At this point, Liu Gaozhuo realized that there was really no way to allocate production capacity, so he had to ask tentatively:

"Then... can you consider expanding production?"

Chang Haonan shook his head:

"The production capacity of WS-10 cannot be increased, mainly because the special-shaped air film holes I designed for the turbine blades and turbine disks are indeed too complicated. The current electrospark-abrasive flow combined process has a long working time. In addition, it still requires manual processing by experienced masters to meet the standards, but there are only a few experienced masters..."

"It's not that I don't want to expand, it's just that I can't..."

Since China's high-temperature alloy materials are not up to standard, in order to ensure sufficient turbine pre-temperature, an extremely complex internal structure of the air film hole had to be designed for the hot end components of the turbofan 10.

It is even more complicated than the hole pattern used by China on the WS-15 in the previous life.

After all, as an engine from the 2020s, the latter can already use fairly advanced high-temperature alloys.

The design difficulty is much smaller.

The cost... is that it is very difficult to increase production capacity.

From the production of prototype No. 01 to the present, although the overall process has been improved several times, the total output has not increased much due to the existence of the speed-determining step of "master craftsmanship".

With no previous life experience to refer to, Chang Haonan could only grope his way forward step by step.

This was also one of the main reasons why he decided to get involved in computational materials science.
