The Military-industrial Scientific Research System of the Academic Master Chapter 594

 Chapter 594 “Refreshed” NH90 (4K)

 Zhang Jiujiang's words actually contain two meanings.

 First, I will definitely have high standards and strict requirements in training and learning, and I will be merciless;

Secondly, I will definitely take care of things other than these two items.

 “That's good, that's good.”

Chang Haonan nodded and replied with satisfaction:

“Strict teachers produce great disciples, so my sister-in-law asked Instructor Zhang...”

He could naturally hear the implication of what Zhang Jiujiang just said, but he didn't say anything nonsense like that he didn't need to be taken care of -

It would have been fine if he had just met Chang Jiayao like a normal student parent, but now after what happened just now, it is no longer possible to keep a low profile.

Whether he said this or not, it was impossible for the school to be completely indifferent to Chang Jiayao.

 In this case, saying so many words would seem pretentious.

 For a while, neither of them spoke again.

And Chang Haonan couldn't rush to explain on his own.

 Compared to the boring and boring teaching building or office building we just saw, this building looks more modern.

“This is our college's new activity center. It is currently the only indoor activity venue that is open to students for a long time after the afternoon classes. It also has a good restaurant inside.”

As he just said, Chang Haonan only waited in the hall for about five minutes when he saw two female trainees with short hair and wearing air force spring and autumn uniforms walking up the steps quickly and pushing the door in from the outside. .

 No matter how funny it is, they will never laugh.

“Are you feeling overwhelmed by the burden of work?”

Chang Haonan said and walked into the activity center.

 Unless you can't help it.

After all, Chang Jiayao is still a girl at heart, and she has only been in school for less than a year. After seeing Chang Haonan, whom she had not seen for more than a year, she ran straight over without caring about her image or regulations.

Chang Haonan rolled his eyes helplessly.

Chang Jiayao came to Chang Haonan. Fortunately, she still had her last bit of sense and did not jump directly into the latter's arms.

"Brother, I thought you had forgotten me..."

At least part of the facade in the middle of the building has a glass curtain wall, which already looks a bit like the 21st century.

“I won't disturb your brother and sister's communication. When you need the car again later, just go to the service desk and call my office.”

 But years of discipline told him that he shouldn't ask this kind of thing.

“That's because you've grown taller during this period. You used to have to raise your head to look at me, but now you just have to look flat...”

So, in the silence along the way, the jeep slowly stopped in front of a building.

“Well, I'll bother Director Zhang.”

"elder brother!"

Zhang Jiujiang got out of the car behind Chang Haonan and introduced at the same time:

This thing is a bit gratuitous, but Chang Haonan just thought that the other party cared about him, so he answered without much thought:

Logically speaking, even if the faces of brothers and sisters who have lived together for more than ten years cannot be clearly seen, they can be easily identified from details such as body shape and posture.

 “I feel like you've become shorter, brother…”

Due to the heavy amount of exercise after entering the flight academy, and the fact that Chang Jiayao is only 18 years old now, she has grown to be almost as tall as Chang Haonan.

 Zhang Jiujiang was naturally curious about Chang Haonan's current status and identity.

 It was still dinner time, and there were not many people in the hall, so his voice almost immediately attracted the attention of Chang Jiayao and the other two.

With this stance, which was similar to a charge, if he hadn't known in advance that the other party was the biological sister of his leader, Zhu Yadan would have even pulled out his gun.

While talking, Chang Haonan and Zhu Yadan had already followed Zhang Jiujiang up the steps to the gate of the activity center.

 But the training in the military academy can make a person undergo earth-shaking changes in this aspect.

 Zhang Jiujiang has arranged things very appropriately.

Zhu Yadan in the back covered her forehead with one hand, obviously having a hard time holding back her laughter.

 Therefore, Chang Haonan didn't finally confirm that the one walking in front was his sister until he recognized the other person's appearance.

 The latter quickly took two steps forward and helped Chang Haonan open the glass door:

“While I was waiting in the office just now, I called their life counselor. Mr. Chang, please wait in the lobby for a while.”

 As guards, they have received strict training.

 A military academy, while belonging to the army, is also a university, so its schedule and management are not as strict as those of combat units.

 It seems that he received the message from the instructor after class and rushed directly from the teaching area.

Chang Jiayao did not continue to stick it on, but looked up and down, and then asked in a hesitant tone:

“Brother...have you been under a lot of pressure lately?”

 “Jia Yao!”

Until now, Chang Haonan had nothing to do with his younger sister, so he could only quietly take a half-step back and put some distance between her and her sister.

 “How could I have forgotten you…”

“Okay, I have a lot of projects on hand, why do you ask this suddenly?”

For a moment, he had some doubts about whether instructor Zhang Jiujiang could train his stupid sister into a qualified pilot.

　　After a brief moment of playing tricks, Chang Jiayao finally remembered that they were not the only two brothers and sisters present, and quickly gathered the girl who had just been behind her:

“Brother, this is my roommate, her name is Liu Yang. She has very good academic performance. I owe my review of several courses to her…”

 Obviously, at this time, she had not realized that her brother had just asked the instructor to be "tough and strict" with her, so she chatted about study-related topics without any psychological burden.

"Hello."

 Liu Yang greeted Chang Haonan timidly.

 The accent of Henan Province.

 No wonder he is the king of roll kings.

“Hello, thank you for helping our Chang Jiayao with her studies.”

Chang Haonan said as he took out a few paper bags from the bag he carried with him:

"I came here from Shengjing this time and didn't have time to buy any gifts. You can take these snacks back to the dormitory and share them..."

 In fact, Chang Haonan feels that Liu Yang is most likely to be China's first female astronaut in the future.

Although this name is really common, if you calculate the age, it should be about the same.

And the place of origin and education status are also consistent.

While Liu Yang was still hesitating, Chang Jiayao had already received it in his hand with a smile on his face:

 “Thank you, bro~”

  The latter will not suffer any loss since he is a sweet talker anyway.

After collecting the gifts, Chang Jiayao turned her eyes to Zhu Yadan, who had been following Chang Haonan just now:

 “Um, brother, is this...sister or...brother?”

  In fact, when she first saw Zhu Yadan just now, her first reaction was -     What a handsome little brother!

 But she soon realized that this might not be the little brother...

　　I was very confused about this for a moment.

 So far, Chang Jiayao still doesn't know what kind of job Chang Haonan is engaged in.

 And the latter seemed to have no intention of letting her know.

 Therefore, after assessing the situation, Zhu Yadan took the initiative to introduce himself:

“My name is Zhu Yadan, Mr. Chang's assistant.”

Speaking like this still reveals some feminine characteristics, so there is no need to answer directly about one's gender.

“Ah, I'm sorry, Sister Yadan...you are so heroic...”

Chang Jiayao continues to travel the world with her sweet words.

"Okay, don't be poor, let's go, I see there is a small stove in this activity center, I will take you two to eat..."

Just when Chang Haonan finally saw his sister.

 Beijing, Institute of Computing Technology, Chinese Academy of Sciences.

Liu Hongbo is in front of a supercomputing console, waiting for the last few results of this round of calculations to be generated.

Similar to the situation when Chang Haonan came here on a business trip two years ago, the reason why he is here is because the 602 Institute in Bingcheng does not have excellent computing conditions, so he had to ask for help from foreign aid.

It's just that like Chang Haonan, he didn't happen to meet a big guy in the algorithm field like Xu Yang to help solve the problem, so basically everything had to be done by himself.

 Behind him, stood another young man who looked to be about the same age as Chang Haonan.

Wang Zhilin, a young technician who was the first to discover problems with the traditional system of Dolphin helicopters during the calculation process.

Of course, this person is relatively "normal", and no one can solve all the problems easily.

However, Liu Hongbo found that he had a good foundation, so he was specially brought here as an assistant this time.

 On another level, of course.

Only by dealing with people like Wang Zhilin a lot, can the former be convinced that it is not that he is too good, but that his junior brother is too inappropriate...

“Teacher Liu, I still can't figure it out. When you were calculating the design of the entire transmission system, why did you add an additional precise limitation on the performance of the bearing set?”

Looking at the calculation section in front of him and not knowing when the results would be available, Wang Zhilin mustered up the courage and asked Liu Hongbo next to him:

“In principle, if this restriction is removed, our calculation amount can be reduced by about 40%.”

“Or, if you are worried that the performance of this bearing group exceeds the standard, you can just add an upper limit. There is no need to limit this area to death..."

 “Is this...”

 Liu Hongbo rolled his eyes slightly.

 I don't know what he wants to say. This is what Mr. Chang specifically emphasized when assigning tasks before.

  The latter said at that time that this gear set must use the performance indicators he gave, without any changes.

 Other parts can be given a higher degree of freedom.

 But in order to ensure his image, Liu Hongbo still gave an explanation after a period of brainstorming:

"It's because after connecting with the European side, we specifically considered their convenience in the parts procurement process. This bearing set is the core component of the transmission system, which determines the upper limit of what the entire equipment can withstand, so we decided to make a comparison first. safe."

 In fact, this explanation was speculated by Liu Hongbo himself and seems to be the most reasonable possibility.

 Hence, it is not difficult to persuade others.

Wang Zhilin's eyes lit up after hearing this:

“This is what you said before. When we design, we can't just think about whether we are comfortable on paper, but we must also try our best to take care of the production and processing process?”

 “That's great, Teacher Liu!”

A round of rainbow farts actually made Liu Hongbo a little embarrassed.

 He touched his nose and nodded:

 “That's right, that's what happened.”

"But this is not what I said, it was said by Mr. Chang. He often emphasizes this point when working on projects. A good designer should not only calculate what is on paper, but also consider how his design should be done. Landing."

Wang Zhilin looked like he suddenly understood, and then asked:

“By the way, Teacher Liu, I've seen Mr. Chang from a distance before, and he seems to be about the same age as me.”

 “Why is he so powerful at such a young age?”

 Liu Hongbo's people are numb—

Why?

 Yeah, why?

He really wants to know too?

 Fortunately, this awkward atmosphere did not last long.

 The last few numbers quickly appeared at the bottom of the calculation log.

Liu Hongbo breathed a sigh of relief when he saw this:

“Write down the numbers, and immediately calibrate the overall performance and process parameters of the entire transmission system, and then send this improvement plan to the Europeans…”

According to the agreement at the time, China should be responsible for the technical solutions for the main rotor, front fuselage and transmission system.

However, considering that the NH90 was a semi-finished project that even had prototypes participating in test flights, Chang Haonan directly followed his own general habit of doing projects and asked Liu Hongbo to prepare and send the most critical transmission system plan first.

 In this way, the two prototypes that are already considered scrapped can be used to test the transmission system in advance.

 Firstly, it is to maximize the residual value, and secondly, it can also save project time.

  Otherwise, if we wait for these three parts to be completed and then test them separately in Europe, it will take at least a few extra months of work.

 This operation of squeezing efficiency to the extreme almost burned out the CPU of Eurocopter at the beginning. After hesitating for several days, I finally realized the huge advantages compared to the traditional solution and agreed.

Of course, Chang Haonan actually had a third-level purpose, but he didn't tell anyone explicitly.

 The design of this transmission system is of course no problem.

However, considering the special performance calibration of the core bearing group, Europeans will inevitably suffer a loss during the test.

If they were careful enough and discovered the problem in time, it should just be a cracked bearing or something similar.

 If it is not done in time, it will most likely eventually lead to overheating of the transmission system, or even direct irreversible damage.

 If you are particularly aggressive, there is even a possibility of a plane crash.

 In short, the aircraft testing this transmission system will definitely not be good.

In this case, using the two aircraft in the scrapped case can at least reduce some losses.

 Otherwise, if the newly built new prototype crashes directly due to transmission system problems, Eurocopter will be severely hit and suspend the project, which will be a complete loss.

“Teacher Liu, everything is calibrated, please take a look!”

A few hours later, Wang Zhilin raised his head again, pointed at the electronic drawings on the computer screen and said to Liu Hongbo.
