The Spring Festival in 1999 came very late, in mid-February.

According to the previously planned schedule, Chang Haonan completed all the single-shot test subjects before then.

Of course, after adjustments.

Approximately 15% of the preset subjects were moved to the back and waited for the second turbofan 10 to be installed.

The power arrangement of the J-11 allows it to complete an engine replacement in a relatively short period of time, but because the AL31F replacement turbofan 10 also involves changes in the internal pipelines of the fuselage, as well as the adjustment of flight control parameters, the efficiency cannot be so fast.

Anyway, we'll have to wait until the next year.

However, for the members of the Turbofan 10 project team, this is not a good thing.

After all, following Chang Haonan to do projects in this mode, although the progress is really fast, but for other colleagues, especially the heads of those subsystems, it is definitely overwhelming.

This one-and-a-half-year continuous rotation does not seem to be a long time, but the fatigue caused by the extremely high work intensity is even higher than that of working for three or four years in a row.

Chang Haonan himself knows this.

So I just took this opportunity to give everyone an annual leave.

The same is true for die forging presses.

It was originally a project as a National Day gift, but the current progress is faster than expected, and there is no hurry for this week or two.

And he himself is also preparing to return to the capital after sorting out and confirming that all the test flight data for more than a month has been saved.

The plane took off from Beiling Airport as usual and arrived at Xijiao Airport.

It's just that this time, in addition to the routine Chang Haonan and Zhu Yadan, I also brought Yao Mengna, who was also preparing to leave Shengjing, by the way.

Regarding Chang Haonan's ability to get mixed with a special plane, she knew it before, but when she actually sat on it, it felt completely different from just looking at it.

In the past two years, she thinks she has pushed her limits.

But the distance between the two is getting farther and farther away......

It can only be said that there is also a gap between the limit and the limit.

After the initial novelty passed, Yao Mengna looked at Chang Haonan, who was resting on the reclining seat next to her, and suddenly said:

"Speaking of which, junior brother, I should graduate this summer."

In this informal setting, she is still used to the name when the two first met.

Chang Haonan calculated the time and realized that Yao Mengna was indeed in the fifth grade of her doctorate.

In her case, it is naturally impossible to postpone it.

"Speaking of which...... Do you not choose to graduate in the spring? ”

Chang Haonan was a little curious:

"I've calculated that if I start to hurry up now, I should still have time to submit the national defense report and dissertation in March, and for graduate students or doctors in classified projects, the graduation qualification review will be carried out separately, and the time card will not be so dead."

"It's been three months......"

Yao Mengna shook her head:

"I did think about graduating in March before, but then the J-11WS project was a bit tight, so I focused on it, and now I ...... I just want to take a good annual leave first. ”

"That's just as well."

Chang Haonan, as a person who has graduated once, also knows that the reason why most people don't choose Chunbi is basically the same as Yao Mengna.

Everyone else is celebrating the New Year, and it's really bad to be the only one writing a big paper.

"What are your plans after graduation?"

Generally, graduate students who have done confidential projects only need to sign a confidentiality agreement, which will not have much impact on their employment choices.

But what he and Yao Mengna are involved in is obviously not a "general" classified project, so there will be certain restrictions on where they can go after graduation.

This was already told before the two of them first participated in the 83 Project.

However, limited is limited, and there are still options to choose.

"I haven't figured it out yet, so ...... I just wanted to talk to you. ”

Hearing this question, Yao Mengna's face showed a somewhat distressed expression:

"Now basically all the factories responsible for the production and research and development of the main engine in the aviation industry have provided me with positions, and the conditions are similar, starting from the associate senior researcher, but there are too many options, which makes me a little confused."

"In addition, if I want to stay in school, whether it is scientific research results or teachers, it will definitely be fine, but I may have to start as a lecturer, and the treatment is worse than that of the company, but the advantage is that I can have a higher degree of freedom and have the opportunity to participate in projects of different systems like the previous two years......"

Obviously, too many offers fell on her head, which made her have difficulty choosing.

Or, at least, self-perceived difficulty in choosing.

Because from Chang Haonan's perspective as an outsider, the paragraph Yao Mengna just said is actually obviously inclined to the latter option.

It just needs someone to convince her.

Moreover, from a practical point of view, it is indeed a better choice to stay in school.

In addition, Chang Haonan is also a little selfish.

So, after thinking for a long time, he replied:

"If you go to the aviation industry, then you have spent most of the time in Factory 112 in the past few years, so there is a high probability that you still have to choose Shengjing, which is more familiar with the situation."

"As for staying in school...... Like you said, the degree of freedom will be a little bit higher, and it's ......"

Speaking of this, Chang Haonan straightened the back of the seat and turned his head to look at Yao Mengna on the other side of the aisle:

"And after I graduate, I should set up a joint laboratory with Beijing Airlines in the name of the Torch Group, and if you stay in school, you are welcome to join at that time."

This matter is something that Chang Haonan has been thinking about for a long time.

If the relatively lean size of the Torch Group is to be maintained, a lot of work cannot be carried out by the Group itself.

But if it is completely handed over to outsiders, then it is difficult for him to rest assured.

Then, the establishment of a school-enterprise joint laboratory, and then by yourself as the director of the laboratory, has become a more secure intermediate choice.

Hearing Chang Haonan's answer, Yao Mengna's eyes also lit up.

If you can continue to work with your own junior and younger brothers after graduation, there is really nothing to hesitate.

Therefore, she nodded almost without hesitation:

"Then it's settled."

"Before you graduate, I'll stay in the school first, and when your joint laboratory is built, don't forget to take me in when the time comes......"

Yao Mengna originally wanted to pretend to be pitiful, but after thinking about it, she felt that it was a bit too pretentious, and finally forgot it.

But Chang Haonan was directly stunned.

Then he realized that his doctoral program was only arranged for two years, and few people should know about it at present.

"Senior sister, actually...... You shouldn't have to wait. ”

"Huh? What do you mean? ”

At this time, Yao Mengna did not realize the seriousness of the matter.

"Because I also graduated this summer."

"......"

Yao Mengna directly performed a pupil dramatic .jpg

"How can you ......"

"You didn't ...... the year before last"

"I did just enroll the year before last."

Chang Haonan nodded:

"But my Ph.D. is set for two years."
