Chapter 844 Production Capacity Allocation of WS-10
No matter what Li Yabo thinks, the candidates for the defense review team have 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 one more person...
"Teacher..."
After Tang Lintian left, Li Yabo, who was numb, came to Chang Haonan and showed a lingering fear:
"I just graduated from college, 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 not a problem for a master's degree. No matter who comes, it is impossible to embarrass you."
Whether it is an undergraduate or a master's or doctoral degree, the key to whether the graduation project passes or not is still the blind review.
Blind review is no problem, so as long as the defense process is not particularly outrageous, it will not be blocked from graduation.
At most, it will be a little ugly on the stage.
Of course, that's what I said.
As the person involved, Li Yabo must be nervous.
Especially since he plans to continue his studies after graduation, he must strive for 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'm going to defend my thesis, I'm nervous."
The latter lay 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 shocking result?"
"That's right, even if the reviewer is looking at his face, it's impossible for you to be embarrassed, right?"
"Besides, undergraduate graduation thesis, aren't they just done casually, just going through the motions and then waking up..."
Several people talked one after another, and the topic gradually shifted from Li Yabo's mentor to their respective graduation projects.
And even their respective futures.
"Alas..."
Li Yabo sighed while lying on the bed.
Obviously, his roommates didn't know what kind of devil-level lineup they would face...
"Anyway, you guys...especially Lao Bai and Wu Pang, who are going to graduate school...I still suggest you prepare well..."
Soon, the day of the defense arrived.
Undergraduate defense is different from graduate defense. Students of one college are divided into several groups, and each group corresponds to the same group of defense teachers.
The whole process basically lasts from the morning to the afternoon of the day.
So, as one of the judges, Chang Haonan got up early that day and arrived at the school about an hour in advance.
However, there were still many people standing in the corridor.
After all, in June, in addition to undergraduates, it is also the peak period for graduate students to defend.
And in the crowd, Chang Haonan happened to meet a familiar face.
Zhou Shuwan.
At this time, the other party also noticed him at the same time.
"Nan... Chang... Professor Chang, what are you doing..."
The moment he saw Chang Haonan, Zhou Shuwan had a terrifying possibility in his mind -
his former classmate was going to be his defense judge...
"Oh, I came here to see the undergraduate defense."
Zhou Shuwan breathed a sigh of relief.
But Chang Haonan asked again.
"What about you? I remember your research group's laboratory is not here, right?"
"I..."
Zhou Shuwan's eyes went dark, and his expression suddenly couldn't hold back:
"Of course I'm here for the graduation defense..."
"..."
Chang Haonan swore that he had indeed forgotten.
Three years after graduating from undergraduate studies, according to the normal progress, wouldn't that be the master's graduation defense...
This is really a bit embarrassing.
"Then...will you continue to study for a doctorate?"
He quickly changed the subject.
"Definitely read it."
Zhou Shuwan also knew that Chang Haonan couldn't have done it on purpose just now. After adjusting his mentality a little, he nodded:
"In the field of aviation life-saving equipment, our country had few systematic studies before. It was only after the introduction of the KD36D ejection seat with Project No. 11 two years ago that it was gradually developed. It was just when manpower was needed."
The J-11 series fighters use the HTY8, which is 100% restored according to the K36D drawings. Its performance is naturally the best in the world like the former.
But the ejection seat needs to be adapted to the aircraft, so there is no way to move the HTY8 directly to other domestic aircraft.
Tactical aircraft are easy to say.
The HTY5 equipped with the J-10 is slightly inferior to the HTY8 in terms of maximum ejection speed, but at least it is a standard third-generation ejection seat.
For large aircraft, such as the H-6, the situation is not very optimistic.
It even maintains the "glorious tradition" of crew members ejecting downwards.
So as Zhou Shuwan said, there is a long way to go in this regard.
Just as the two were about to finish their small talk, a voice suddenly came from behind Chang Haonan.
It sounded familiar.
"Mr. Chang."
Chang Haonan turned around.
It was Liu Gaozhuo.
The general commander of Project No. 11.
Although he did not have as much contact with Chang Haonan as He Ming, who was in charge of production, they were old acquaintances.
"You were also invited here... to be a defense reviewer?"
According to regulations, the defense committee of graduate students must have members from other units.
Just like when Chang Haonan defended his doctoral thesis, he invited Yuan Xiangya and Mr. Qian.
"The main thing is to come to the meeting and be a judge by the way."
While talking, Liu Gaozhuo also noticed Zhou Shuwan who was opposite Chang Haonan:
"Hey, it seems that 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 alone after the defense is over."
Before walking into the conference room opposite, Liu Gaozhuo leaned next to Chang Haonan and whispered.
The latter was stunned for a moment, then nodded:
"Can."
"But it may take me a little longer. You can meet me at the computing center at four o'clock in the afternoon."
…
The process of Li Yabo’s defense was smooth sailing.
There was no situation where Chang Haonan was talking to other scholars on his behalf——
If he couldn't handle even this small scene, Chang Haonan wouldn't have been able to recruit him in the first place.
However, this was a hardship for the other people in the same group as Li Yabo.
Especially two of them who are also preparing to further their studies.
Normally, when encountering a more acute problem, the teacher would still dare to stand up and help with a few words.
And now this scene...
Three academicians, one president, and another Chang Haonan.

To sum it up, this is——
Answer and answer, just answer and not defend. Once you ask a question, apologize like crazy...
Of course, I gave it all in the end.
after all……
Card graduates, that is simply not a person.
Moreover, for Jinghang students, no matter how hard they paddle, there is still a bottom line, and there are no particularly outrageous situations.
After the entire defense process was over, Chang Haonan first asked Tang Lintian to send Wang Yuanguang and Huang Yunbo to the canteen of Torch Group, while he went back to the office alone.
Liu Gaozhuo was waiting there as promised.
"Mr. Liu, what you said during the day was..."
The two sat down on the two sofas respectively, and Chang Haonan asked straight to the point.
"Mr. Chang, that's it."
Liu Gaozhuo explained:
"In accordance with the needs of the Air Force and combined with the progress of the Project 11 improvement project, we are prepared to deliver six trial production batches of J-11B fighter jets to the Air Force for early use in small batches."
"That's a good thing."
Chang Haonan filled the other party's glass of water:
"Whether it's the aircraft itself or our power, if the Air Force is willing to accept small batch trials, the progress will be much faster."
Liu Gaozhuo was holding a cup in one hand and arranging his hair with the other hand a little embarrassedly:
"The main thing is... our factory wants to try its best to hand over these aircraft before the end of this year, but the comrades at Liming said that by December, only 6 turbofan 10A engines can be provided at most. Look at this... …”
Chang Haonan understood.
This is to ask for production capacity.
Because Project No. 10 and Project No. 11 are advancing at the same time, and both require turbofan 10 as power, the already low production capacity is even more stretched.
Especially after entering 2000, the J-10A built two new single-seat aircraft, 03 and 04, and a two-seat prototype aircraft 05. Counting backup, the demand for the turbofan 10B increased immediately.
The production capacity allocated to model A will naturally decrease.
"well……"
After thinking for a while, Chang Haonan sighed and replied:
"Mr. Liu, let me tell you directly. In the second half of the year, the total output of turbofan 10 is 10 units. Project 10 has three prototypes under construction. That's 3 units. There will always be backup engines. One unit is left, so the production capacity of these six 10A turbofans has indeed come to an end.”
"We are all brothers, and it is impossible for me to cut off their supply for Project No. 10..."
When it came to this matter, Liu Gaozhuo finally realized that he had no choice in terms of production capacity allocation, so he had no choice but to ask tentatively:
"Then...can we consider expanding production?"
Chang Haonan shook his head:
"The production capacity of Turbofan 10 cannot increase, mainly because the special-shaped air film holes I originally designed for the turbine blades and turbine discs were too complicated. The current combined EDM-abrasive flow process requires long working hours, and there will be more to come later. It requires manual processing by experienced masters to reach the standard, but there are only so many masters..."
"It's not that I don't want to expand, it's just that I can't expand..."
Since China's high-temperature alloy materials are not up to standard, in order to ensure sufficient temperature in front of the turbine, an extremely complex internal structure of the air film hole had to be designed for the hot end component of the turbofan 10——
It is even more complicated than the hole pattern used by China on the turbofan 15 in the previous generation.
After all, the latter, as an engine in the 2020s, can already use quite advanced high-temperature alloys.
The design difficulty is actually much smaller.
The cost...is that it is quite difficult to ramp up production capacity.
From the production of prototype No. 01 to the present, although the overall process has been improved for several rounds, the total output has not improved much because of the speed-determining step of "master craftsmanship".
Without any past life experience for reference, Chang Haonan could only fumble forward step by step.
This was one of the main reasons why he decided to get involved in computational materials science.
