Zhang Jiujiang's words actually contain two meanings.

First, I will definitely have high standards and strict requirements in terms of training and study, and I will not show any mercy;

The second is that I will definitely take care of some of the places outside of these two items.

"That's good, that's good."

Chang Haonan nodded and replied with satisfaction:

"The strict master is a high apprentice, and the sister will ask Instructor Zhang......"

He could naturally hear Zhang Jiujiang's voice just now, but he didn't say anything nonsense like he didn't need to take care of-

It would have been fine if he had met Chang Jiayao in the way of a normal student's parents, but now after such a thing just now, there is no possibility of acting in a low-key manner.

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

In this case, it seems hypocritical to say so much.

For some time afterward, neither of them spoke again.

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

But years of discipline taught him that this kind of thing should not be asked.

And Chang Haonan couldn't rush up to explain it himself.

So, in the midst of such a wordless journey, the jeep slowly stopped in front of a building.

Compared to the cookie-cutter and slightly dull teaching or office buildings I just saw, this building is a little more modern.

At least part of the building's façade is made of glass, which looks a bit 21st century.

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

"This is our new activity center, the only indoor activity space that is open to students for a long time after the afternoon classes, and there is a nice restaurant inside."

A military academy is not only a university but also a university, so neither the schedule nor the management is as strict as that of a combat unit.

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

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

"When I was waiting in the office just now, I called their life counselor, and Mr. Chang you waited in the hall for a while."

"I won't disturb your brother and sister's contact relationship, and when you need to use the car again, just go to the service desk and call my office."

"Okay, I'll bother Director Zhang."

Chang Haonan said and walked into the activity center.

Zhang Jiujiang has arranged things very properly.

As he said just now, Chang Haonan only waited in the hall for about five minutes before he saw two female cadets with short hair and wearing the regular spring and autumn uniforms of the Air Force walking up quickly along the steps and pushing the door from the outside.

It stands to reason that even if the siblings who have lived together for more than ten years can't see their faces clearly, they are easy to identify from details such as posture and posture.

But the training of military schools can make a huge difference in this area.

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

It seems that I should have received a message from the instructor after class, and then rushed directly from the teaching area.

"Jia Yao!"

It was still dinner time, and there weren't too many people in the hall, so his voice almost immediately attracted the attention of Chang Jiayao and the others.

"Brother!"

Chang Jiayao is still a girl after all, and it has only been less than a year since she entered school, and after seeing Chang Haonan, who she hadn't seen for more than a year, she didn't care too much about her image and regulations, so she flew straight over.

With this posture like a charge, if it weren't for knowing in advance that the other party was the sister of his own chief, Zhu Yadan would probably have even taken out his gun.

"Brother, I thought you forgot about me......"

Chang Jiayao came to Chang Haonan's side, but fortunately, she still had the last bit of reason and did not directly pounce into the latter's arms.

"How could I have forgotten you......"

For a long time, Chang Haonan didn't have much to do with his sister, so he had to quietly take a half step back and open up some distance.

And Chang Jiayao didn't continue to paste it, but looked up and down, and then asked in a somewhat hesitant tone:

"Brother...... Have you been stressed lately? ”

This thing is a bit unreasonable, but Chang Haonan only thinks that the other party cares about him, so he replied without thinking too much:

"It's okay, there are more projects at hand, why do you suddenly ask this?"

"I feel like you're getting shorter...... brother"

"Are you weighed down by the weight of your work......?"

Zhu Yadan in the back covered his forehead with one hand, obviously holding back his smile very hard.

As guards, they are all highly trained.

No matter how funny it is, they won't laugh.

Unless you can't help it.

Chang Haonan rolled his eyes helplessly.

Due to the large amount of exercise after entering the flight academy, and Chang Jiayao is only 18 years old now, she has jumped to the same height as Chang Haonan.

"That's because you've grown taller again during this time, and you used to have to look up at me, but now you can just look at it flat......"

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

After a short period of juggling, Chang Jiayao finally remembered that it was not only their brothers and sisters who were present, and hurriedly brought the girl who had just followed her:

"Brother, this is my roommate, her name is Liu Yang, her academic performance is very good, and I have reviewed several courses thanks to her......"

Obviously, at this time, she didn't realize that her brother had just asked the instructor to be "difficult and strict" with her, so she talked about topics related to learning without any psychological burden.

"Hello."

Liu Yang said hello to Chang Haonan a little timidly.

Yu provincial accent.

No wonder it's the king of the rolls.

"Hello, thank you for helping us in your studies."

Chang Haonan said and took out a few paper bags from the bag he was carrying:

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

In fact, Chang Haonan feels that this Liu Yang is most likely the first female astronaut in China in later generations.

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

Moreover, the place of origin and education are also correct.

Liu Yang was still hesitating, and Chang Jiayao had already received it with a smile:

"Thank you, brother~"

The latter will not suffer if it focuses on a sweet mouth anyway.

After putting away the gift, Chang Jiayao's gaze turned to Zhu Yadan, who had been following Chang Haonan just now:

"That, dude, this ...... My sister is still ...... Brother? ”

In fact, when she saw Zhu Yadan at first glance just now, her first reaction was-

What a handsome little brother!

But soon she realizes that this may not be the little brother......

I was very confused for a moment.

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

And the latter didn't seem to mean to let her know.

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

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

When he talks like this, he still exposes some feminine characteristics, so he doesn't have to answer his gender positively.

"Ah, I'm sorry, Sister Yadan...... You're so heroic......"

Chang Jiayao continued to walk the world with a sweet mouth.

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

……

At the same time that 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 in this round of calculations to be generated.

Similar to Chang Haonan's business trip here two years ago, the reason why he is here is also because the 602 Institute in Bingcheng itself really does not have strong calculation conditions, so he has to ask for foreign help.

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

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

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

Of course, this one is relatively "normal" a lot, and no one has solved all the problems easily.

But Liu Hongbo still found that he had a good foundation, so he brought it over as an assistant this time.

On another level, of course.

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

"Mr. Liu, I still can't figure it out, why do you need to add a precise limit for the performance of the bearing group when you calculate the design of the whole set of transmission system?"

Looking at the calculated cross-section in front of him who didn't know when the result would be available, Wang Zhilin plucked up his courage and asked Liu Hongbo next to him:

"In principle, if we remove this qualification, we can reduce the amount of computation by about 40%."

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

"What ...... this?"

Liu Hongbo rolled his eyes slightly.

He wanted to say that I don't know either, which was specially emphasized by President Chang when he sent the task before.

The latter said at the time that the gear set must use the performance indicators he gave and could not change in the slightest.

The rest of the parts can be more free.

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

"It's because after docking with Europe, we have considered their convenience in the procurement process of parts, and this bearing group is the core component of the transmission system, which determines the upper limit of the whole set of equipment, so it is safer to set it first."

In fact, this explanation is also the most reasonable possibility that Liu Hongbo has speculated on himself.

Therefore, it is not difficult to convince others.

Wang Zhilin's eyes lit up after hearing this:

"That's what you said before, when we do design, we can't just patronize whether we are comfortable on paper or not, but also try to take care of the production process?"

"That's amazing, Mr. Liu!"

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

He touched his nose and nodded:

"yes, that's what happened."

"But this is not what I said, it is always said, and he often emphasizes this point when he is working on projects, a good designer should not only calculate what is on paper, but also think about how to implement his design."

Wang Zhilin made a sudden realization, and then immediately asked:

"By the way, Mr. Liu, I have seen Mr. Chang from afar before, and I feel as if he is about the same age as me."

"Why is he so young and so powerful?"

Liu Hongbo's people are numb-

Why?

yes, why?

He wants to know too?

Fortunately, this awkward atmosphere did not last long.

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

"Whew-"

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 drivetrain, and then you can send this set of improvements to the Europeans......"

According to the agreement at that time, the Huaxia side should be responsible for the technical scheme of the main rotor, the front fuselage and the transmission system.

However, considering that NH90 is a semi-finished project that even has a prototype to participate in the test flight, Chang Haonan directly followed the general habit of doing his own project, and asked Liu Hongbo to send the most critical transmission system scheme first.

In this way, the drivetrain can be tested in advance with the two prototypes that can already be considered scrapped.

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

Otherwise, if you wait for all three parts to be completed, and then go to Europe to test them separately, it will take a few extra months of work.

At the beginning, the operation of squeezing the efficiency to the extreme almost burned the CPU of Eurocopter, and after hesitating for several days, I finally realized the huge advantage over the traditional solution, so I agreed.

Of course, Chang Haonan actually has a third-level purpose, but he hasn't told anyone about it.

The design of this drivetrain, of course, is no problem.

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

If they were cautious enough to catch the problem in time, it would have been just a crack in the bearing or something like that.

If it is not timely, it will eventually evolve into overheating of the transmission system, or even direct irreversible damage.

If it is particularly hard, there is even a possibility of a crash.

In short, the aircraft that tested this transmission system must not be able to fall well.

In this case, with those two scrapped planes, it is possible to reduce some losses.

Otherwise, if the new prototype crashed directly due to a drivetrain problem, Eurocopter was hit hard and aborted the project, but it would be completely out of the way.

"Teacher Liu, everything is calibrated, come and take a look!"

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