The military-industrial scientific research system of the academic master.

After solving the key technical issues that hindered the production of single-crystal turbine blades, the turbofan 10 has entered the component-level production and testing process.

This is another stage where Chang Haonan can relatively let go.

After all, Liming Factory still has some capabilities, and there is no need for him to go out and screw in it himself.

As for testing…

For component-level testing, Chang Haonan is quite confident that he can go through it again and again.

And even if there are some minor problems, the entire team has been working with him for a year, so he won't have to teach everything step by step.

As for the die forging press...

After all, although they are both under the category of casting, there are still a few million differences between single crystals made by directional solidification and their large-scale castings.

At most, we can learn from each other’s experiences in dealing with shrinkage porosity.

Therefore, several engineers responsible for producing movable beams had actually gone back to optimize their own process parameters earlier.

After all, the project schedule was to have the equipment in trial production by October 1999.

For a behemoth with a dead weight of over 20,000 tons, it would take at least about half a year to transport the various subsystems from the place of production to Jiangcheng and then install them, not to mention the subsequent equipment debugging. , the time actually left for them to produce is actually not very abundant.

Therefore, Chang Haonan decided to take advantage of this hard-earned gap between the two projects to give himself a little vacation.

By the way, I went north to the Air Force Aviation School in Changchun and took a look at Chang Jiayao who was studying there.

However, now that he is in his current position, he can no longer do as he pleased with every move in his personal life as he did in the past.

It doesn't matter if it's just in the capital or between these units within the Science and Technology Commission system, but if you want to go somewhere else, you have to make a report first.

It doesn't involve any issues like approval.

The main thing is to let the organization know where you are.

If anything happens, you can always respond.

There is nothing we can do about this.

While the importance and right to speak are gradually increasing, it is inevitable that a small price of freedom must be paid.

Chang Haonan's current importance is self-evident. Although there is no such term as "strategic scientist" at the moment, his actual functions are almost the same.

Including daily security, although Zhu Yadan is here, it is enough to deal with some ordinary accidents, but in this age when social security is difficult to reassure, Ding Gaoheng still often needs to personally intervene and make arrangements.

The last person to receive such treatment was Mr. Qian.

Coincidentally, the person who arranged security work for Mr. Qian happened to be Ding Gaoheng's father-in-law...

In short, when Chang Haonan finally made it all the way to the destination, it was already several days later.

Although the Air Force Aviation School is a school, it is an active unit at the deputy corps level of the People's Liberation Army.

Except for a few special circumstances, the students there are automatically deemed to have enlisted in the army when they enroll, receive the rank of air force cadets and start counting their military years. The instructors and teachers are all active-duty officers.

Naturally, it is impossible for people to wander around this kind of place like a normal university campus.

They are all managed in a closed manner.

Therefore, when Chang Haonan arrived at the gate of the school in a dusty Jetta that came from Shengjing, he was stopped by the sentry as expected.

Since there were many incidents in the past two years where criminals attacked sentries and then grabbed guns and committed crimes again, by 98, the sentries at the entrance of the compound were basically in groups of two, with guns and ammunition separated.

"Comrade, there is a military control area ahead. Civilian vehicles need to show their IDs to enter."

I don't have any documents, of course.

Zhu Yadan theoretically has the rank of captain of the armed police, but he is not in the same unit and is of no use.

According to general custom, in order to show respect for the sentry, Chang Haonan chose to get out of the car to negotiate with the other party:

"I'm……"

He hesitated briefly, feeling that the relationship between brother and sister seemed a bit unconvincing, so he changed his explanation:

"I'm a parent of a student. I've been having a break recently and wanted to come over for a visit."

However, his explanation, coupled with the hesitation just now, made the sentry suspicious.

Mainly under normal circumstances, when talking about parents, the basic default is to be the elders.

As for Chang Haonan's appearance, it doesn't look like he could have a child going to college.

In fact, the sentry felt that he looked like a college student.

"Are you... a parent of a student?"

The other party frowned:

"Okay, which student in which department and class you want to visit, I will contact their instructor for you."

Now, Chang Haonan felt a little embarrassed——

The two of them haven't seen each other since Chang Jiayao finished her college entrance examination, so he actually doesn't know his sister's specific major and class.

"Uh...I don't know which class I'm in, but I'm a freshman this year, and my name is Chang Jiayao. There shouldn't be many female students in your college, so it's easy to find one."

The sentry glanced up and down at Chang Haonan:

“Student parents, don’t know which class your child is in?”

At this time, he had already listed Chang Haonan as a highly suspect.

This suspicion does not mean that the latter is a spy.

Instead, I feel that this may be the boyfriend of the female student, using the name of the parent to find someone to come out...

According to the regulations in the army, it is obviously impossible to go out for a date during the working day.

Thinking of this, the sentry thought to himself: How could such a trivial trick deceive me?

His eyes became sharper.

Of course, he couldn't directly drive away the people who claimed to be the students' parents.

However, there are other ways to deal with such young people who are in love:

"I can contact Chang Jiayao's instructor, but we have the information of the student's parents. If we can't match it by then, you may be suspected of violating my country's Military Facilities Protection Law..."

Under normal circumstances, if you really want to date a female student, you should find a reason to run away at this point.

But Chang Haonan had a clear conscience on the one hand, and on the other hand he didn't know the sentry's inner thoughts at all. He just regarded it as a routine statement and nodded with almost no thought.

In fact, he had a letter of introduction stamped by the Shengjing Military Region Air Force Command in his arms.

But if this thing was taken out, the impact would be a bit big, and it might even be a burden to Chang Jiayao, so she chose to take the normal route of visiting the student's parents.

The other party was a little shocked when he saw this unsophisticated person. He turned around and trotted back to the post, picked up the phone and started calling people.

He even specifically asked the other party to bring two more people out to prevent this bold and high-risk subject from causing trouble.

Soon, an open-top off-road vehicle sped past the school gate.

An Air Force colonel wearing the classic "army top, navy trousers" uniform stepped out of the co-pilot's seat, followed by two soldiers.

He negotiated with the sentry for a few words, and then looked towards Chang Haonan.

Together, several people strode up to the latter aggressively:

"Hello, I am Comrade Chang Jiayao's instructor. Please show me your ID and the information we have here..."

Before he finished speaking, the air force colonel was stunned for a moment.

Immediately afterwards, the originally guarded expression suddenly relaxed, and he shouted in a somewhat unbelievable voice:

"Mr. Chang?"

This sound also reminded Chang Haonan of the identity of the officer opposite:

"Are you...Zhang Jiujiang, instructor Zhang?"
