Chapter 594 "Renewed" NH90 (4K)
Zhang Jiujiang's words actually contain two meanings.
Firstly, I will definitely have high standards and strict requirements in terms of training and learning, and will not show mercy at all;
Secondly, in other areas other than these two items, I will definitely still be able to Take care of some.
“That’s good, that’s good.”
Chang Haonan nodded and replied with satisfaction:
"Strict teachers produce great disciples, so my sister-in-law entrusts instructor Zhang..."
Of course he could hear the implication of what Zhang Jiujiang just said, but He didn’t say anything nonsense like he didn’t need to be taken care of——
It would have been fine if he had just met Chang Jiayao like a normal parent of a student, but now after what happened just now, he has already There is no possibility of keeping 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 more words would seem pretentious.
For a while, neither of them spoke again.
Zhang Jiujiang was naturally curious about Chang Haonan's current identity and status.
But years of discipline told him that he shouldn't ask this kind of thing.
And it was impossible for Chang Haonan to rush to explain on his own.
So, in such silence all the way, the jeep slowly stopped in front of a building.
Compared with the same and dull teaching building or office building that I just saw, this building looks more modern.
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.
Zhang Jiujiang followed Chang Haonan out of the car and introduced at the same time:
“This is our college’s new activity center. It is currently the only one open to students for a long time after the afternoon classes. An indoor event venue with a nice restaurant inside. ”
The military academy, while belonging to the army, is also a university, so neither the schedule nor the management is as strict as a combat unit.
While talking, Chang Haonan and Zhu Yadan had already followed Zhang Jiujiang up the steps to the gate of the activity center.
The latter quickly took two steps forward and helped Chang Haonan open the glass door:
"While waiting in the office just now, I called their life counselor. Chang Haonan Please wait in the lobby for a while."
"I won't interrupt your brother and sister's communication. When you need the car again, just call my office at the service desk."< br>
"Well, I'll bother you, Director Zhang."
Chang Haonan said and walked into the activity center.
Zhang Jiujiang has arranged things very appropriately.
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. Push the door open from outside.
Logically speaking, even if the faces of brothers and sisters who have lived together for more than ten years cannot be seen clearly, they can be easily identified from details such as body shape and posture.
But the training in the military academy can make a person undergo earth-shaking changes in this aspect.
Therefore, Chang Haonan didn't finally confirm that the one walking in front was his sister until he recognized the other person's appearance.
It seems that he received the message from the instructor after class and rushed directly from the teaching area.
“Jia Yao!”
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 Chang Jiayao.
"Brother!"
After all, Chang Jiayao is still a girl at heart, and she has only been in school for less than a year. After meeting Chang Haonan, whom she hadn't seen for more than a year, she didn't care about too much image and regulations. , flew straight over.
With this stance, which was the same as charging, if he hadn’t known in advance that the other party was the sister of his leader, Zhu Yadan would have even pulled out his gun.
"Brother, I thought you had forgotten me..."
Chang Jiayao came to Chang Haonan. Fortunately, she still had the last bit of reason left and did not pounce directly. into the latter's arms.
"How could I forget you..."
For a long time, Chang Haonan had nothing to do with his sister, so he had to quietly take a half step back and put some distance between her.
Chang Jiayao did not continue to stick to it, but looked up and down, and then asked in a hesitant tone:
"Brother...have you been stressed recently? "Big?"
This thing is a bit unreasonable, but Chang Haonan just thought that the other party cared about him, so he replied without thinking too much:
"It's okay. I have a lot of projects on hand. Why do you ask this suddenly?"
"I feel like you have become shorter..."
"Are you affected by the heavy workload? It’s so stressful...”
Zhu Yadan in the back covered her forehead with one hand, obviously having a hard time suppressing her laughter.
As guards, they have received strict training.
No matter how funny it is, they will never laugh.
Unless you can't help it.
Chang Haonan rolled his eyes helplessly.
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.
"That's because you've grown taller during this period. You used to have to look up at me, but now you just have to look flat..."
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 pulled over the girl who had just been following her:
"Brother, this She is my roommate, her name is Liu Yang, and her academic performance is very good. 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 review her. "Be strict with the hard", so we chatted about study-related topics without any psychological burden.
“Hello.”
Liu Yang greeted Chang Haonan timidly.
Henan accent.
No wonder he is the king of roll kings.
"Hello, and thank you for helping our Chang Jiayao with her studies."
Chang Haonan said and took out a few paper bags from the bag he carried:
"I came here from Shengjing this time, so I didn't have time to buy any gifts. You can take these snacks back to the dormitory and share them..."
In fact, Chang Haonan felt that this Liu Yang was most likely to be the future generations. China's first female astronaut.
Although this name is really common, if you calculate the age, it should be about the same.
And the place of origin and education also match.
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 is a sweet talker and won't suffer.
After collecting the gifts, Chang Jiayao turned her eyes to Zhu Yadan, who had been following Chang Haonan at a distance:
"Um, brother, is this...sister or...brother? ”
Actually, when she first saw Zhu Yadan just now, her first reaction was - what a handsome little brother!
But soon she realized that this might not be the little brother...
This made her very confused 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."
Such a speech still revealed some feminine characteristics, so he There is no need to answer your gender directly.
"Ah, I'm sorry, Sister Yadan... you are too heroic..."
Chang Jiayao continues to rely on her sweet words to dominate the world.
"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..."
...
I finally saw Chang Haonan. At the same time as my 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.
It was similar to the situation when Chang Haonan came here on a business trip two years ago. The reason why he was here was because the 602 Institute in Bingcheng did not have good 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.
But Liu Hongbo still found that he had a good foundation, so he was specially brought here as an assistant this time.
Of course, on another level.
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 limiting condition for the performance of the bearing set?"
Looking at the calculation section in front of him and he didn't know when the results would be available, Wang Zhilin mustered up his courage. Asked Liu Hongbo next to him:
"In principle, if we cancel this restriction, 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 only add more An upper limit is enough, 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 he sent out tasks before.
The latter said at the time that this gear set must use the performance indicators he gave, without any changes.
Other parts can be more free.
But in order to ensure his own image, Liu Hongbo gave an explanation after brainstorming:
“It’s because after connecting with Europe, they specifically considered their parts and components. Convenience in the procurement process, this bearing group is the core component of the transmission system, which determines the upper limit of what the entire equipment can withstand, so it is safer to decide on it first.”
In fact, this explanation is also Liu Hongbo’s own speculation. It seems to be the most reasonable possibility.
Therefore, 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 care about whether we are comfortable on paper, but we must also try our best to take care of ourselves. To the production and processing process?”
“That’s awesome, Teacher Liu!”
The rainbow fart actually made Liu Hongbo a little embarrassed.
He touched his nose and nodded:
"Yes, that's what happened."
"But this was not said by me, but by Mr. Chang. He was working on a project. I often emphasize this point when I was working on the project. A good designer should not only calculate what is on paper, but also consider how to implement his design."
Wang Zhilin seemed to have a sudden realization, and then asked. :
“By the way, Teacher Liu, I saw Mr. Chang from a distance before, and he seemed to be about the same age as me.”
"How come he is so powerful at such a young age?"
Liu Hongbo is so numb——
Why?
Yes, 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.
“Huh——”
Liu Hongbo breathed a long sigh of relief when he saw this:
“Write down the numbers, and immediately do the overall performance and craftsmanship of the entire transmission system. Parameter calibration, and then this improvement plan can be sent 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 can be 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.
And 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, you may even crash.
In short, the aircraft testing this transmission system will definitely fail.
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.
