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

The reason for getting stuck is also very simple.

Writing textbooks is different from writing papers.

He cannot assume that readers are all industry insiders with a certain academic foundation and go straight to the point after a brief abstract and introduction.

For example, if he wants to talk about computational simulation now, he must first talk about what computational simulation is and how to perform computational simulation.

In short, when Ms. Zhou Li finished washing the dishes and walked out of the kitchen, she saw her precious son staring blankly at a shiny screen.

"Xonan?"

The mother's voice finally made Chang Haonan react:

"Ok?"

"What are you..."

Zhou Li walked to the bed and looked at the machine in front of Chang Haonan with curiosity.

"A computer? It's so small?"

Thanks to the country's emphasis on education, most middle schools already had computer rooms and (at least on paper) computer courses in the 90s, so Zhou Li, as a teacher, has naturally seen computers.

It's just that laptops are still a new gadget for most Chinese people in this era.

"Well, yes, it's called a laptop. My instructor gave it to me to facilitate my work."

Chang Haonan looked away from the screen and looked at his mother not far away.

Anyway, I just worked overtime because I had nothing to do. Now that I have no ideas, I might as well give it up for now.

Zhou Li's attention did not stay on the computer for a long time, but she showed a look of hesitation:

"Xiao Nan, mom has something to ask you."

"You say."

Chang Haonan sat slightly on the bedside and made room for his mother.

"You specialize in aircraft, then..."

Halfway through, Zhou Li turned her head and glanced at Chang Jiayao's bedroom door:

"Tell me the truth, is being a pilot dangerous?"

Perhaps because of the news that night, she was obviously worried about Chang Jiayao's choice again:

"Your dad has been a policeman for most of his life. To be honest, every time he is on duty, although he knows that there is not much going on in this small county, he still feels a little worried."

"Now that he has finally made it to his old age, he has transferred to an administrative position and no longer has to work. Jia Yao is going to be a pilot again. This..."

Looking at his worried mother, Chang Haonan didn't know how to answer this question for a moment.

He could not deceive the other party that piloting was a safe profession.

But he didn't want to worry his parents too much or destroy Chang Jiayao's dream.

After the phone call shortly after their rebirth, the brother and sister talked about this matter several times. Chang Haonan was very sure that his sister was not acting on a whim.

Whether it's because he wants to escape from the shadow of his brother, or he really likes it, or he yearns for flying.

In short, Chang Jiayao is indeed preparing very seriously.

He even arranged a daily exercise plan for himself.

"Mom, nothing is absolutely safe."

After a long silence, he managed to organize his words.

The first thing to do is to stabilize Zhou Li's mood:

"Based on our country's current policy, we will not arrange for female pilots to fly fighter jets."

Zhou Li's complexion improved slightly.

Although she didn't know much about airplanes, even if she only read the news, she could probably tell that those small airplanes with violent movements were more dangerous than the large, steady airplanes.

"If you are just flying a passenger plane or a transport plane, the safety factor is generally very high. Think about it, if it were so easy to get into trouble, no one would be willing to travel by plane. But in recent years, the number of civil aviation passengers has been increasing. That’s a lot.”

Chang Haonan slightly changed the concept. There is still some difference between military transport aircraft and civilian transport aircraft.

But that's not important.

"The plane that crashed in the news just now..."

Sure enough, it was still because of this.

“It’s just because there are so few air accidents that it’s on the news.”

In this case, Chang Haonan had no choice but to resort to sophistry.

In order not to give Zhou Li time to think clearly, he quickly continued his analysis seriously:

"Although the cause of the accident is still uncertain, there are only a few reasons why the plane crashed at the airport."

Chang Haonan stretched out a finger:

"Either it was intentional by the pilot as speculated in the news, then it has nothing to do with flight safety. In this case, if you really want to say it, flying your own plane is more secure than flying."

The half-joking tone made Zhou Li's mouth corners rise slightly.

"Either it is a mechanical failure, such as an engine shutdown, etc. This is related to ground inspection. Our domestic airlines are much more serious about this than the foreigners, and there is nothing to worry about."

"Or another possibility is external conditions, such as icing on the wings."

When he said this, Chang Haonan's heart suddenly thumped.

The crash situation of this EMB120 does seem a bit like a certain Y-8 in the previous life...

But now he didn't have time to think about it, so he quickly continued:

"It just so happens that I study passenger aircraft flight safety issues. In this regard, our country's level is much higher than that of Europe."

Hearing what Chang Haonan said, Zhou Li's eyes widened in surprise.

Since the 1980s, a large number of products and cultures from developed countries in Europe and the United States have been imported in an almost barbaric and out-of-control manner, which has had a huge impact on China.

One of the most intuitive effects is that the Chinese people have gradually lost confidence.

And it is comprehensive and subtle.

Even a teacher from a small county like Zhou Li cannot avoid this.

When she heard that China's research level was higher than that of Europe, even if this sentence was said by her own son, her first reaction was disbelief.

"Are we? Better than Europe?"

"Of course."

In any case, the worried look on Zhou Li's face has faded a lot, so Chang Haonan naturally strikes while the iron is hot:

"This is the direction that your son and I are researching. I dare not talk about it in other fields. When it comes to dealing with ice on the wings, if we are second to none, no one dares to be first!"

……

Just as Chang Haonan was at home dispelling Zhou Li's concerns about the occupational risks of pilots.

Skardu Airport, Kashmir.

Two fighter jets with slender bodies appeared on the horizon with the roar of getting closer and closer.

The lights on the landing gear and the red and green wing lights on the left and right indicated that they were descending to the desired height and that the landing gear had been lowered and ready for landing.

The landing lights on the airport runway have also been turned on.

A few minutes later, the two planes landed on two runways of 3600 meters and 2600 meters respectively.

After the plane came to a stop, the ground staff who had been on standby for a long time rushed forward with auxiliary vehicles and dragged the two planes into the reinforced aircraft castle at the end of the runway as quickly as possible.

With the bright lights inside the aircraft fort, one can recognize that these are two of the four J-8Cs that were just received by the First Air Division at the beginning of the year.

A group of soldiers with East Asian faces quickly began various inspections after landing, and took off a total of eight PL-8 air-to-air missiles hanging under the wings for maintenance.

Another group of ground staff, generally bearded, pulled up the gangway and were ready to repaint the aircraft.

Zheng Liangqun and Chen Jialiang climbed out of the aircraft cockpit with some difficulty.

The two were the deputy division commander and chief of staff of the First Kong Division respectively, and had been stationed in Tibet Province for a week before.

In fact, in terms of age, they are no longer suitable for long-term toil at the plateau airport.

But there is no way. The J-8C is originally a new equipment, and there are not many pilots who can drive it skillfully and use semi-active radar bombs.

And the training level of the Chinese Air Force in the mid-90s is hard to describe.

Even basic night flight training can only be carried out by a small number of key aviation regiments under the leadership of the regiment commander.

So after sifting through a circle, I couldn't find any young pilots who met the requirements, so I had to let two veterans take over.

As for why they drove fighter jets all the way to this strange land just before the Chinese New Year.

Naturally, this is to deal with the three-sonic squadron that has become increasingly rampant in recent months and has repeatedly penetrated the airspace of the two countries for reconnaissance and retreated unscathed.

After being locked by the surface-to-air missile array during their first reconnaissance, they optimized their flight route and chose to avoid the fixedly deployed Hongqi 2B A missile array.

Therefore, the only anti-aircraft missile with theoretical interception possibility has lost its effect.

However, the previous rounds of failed attempts were not without success. At least they allowed the Pakistan Air Force to roughly grasp the activity patterns of the opponent's reconnaissance aircraft.

One of the most important ones is——

For some unknown reason, the top speed of those MiG-25s seems to be limited, so they usually choose 2.2 times the speed of sound and an altitude of 2.3 meters to cut in from the direction of northern Afghanistan, and then maintain level flight until they turn eastward near Jammu and return.

Of course, for aircraft such as Mirage 3 or F16A, knowing this information is meaningless. They have no means at all to shoot down the opponent.

Except for Sammy, who took a photo on the first interception, all they could see the next few times was the trail cloud left by each other.

However, after the J-8C was delivered to the Chinese Air Force for trial use, the situation was different.

Although the J-8C only flew above the ceiling of 22500 meters during test flights, it will further drop to about 21000 meters after loading bombs.

However, the Pili 30 missile, which is semi-active radar guided and has a head-on attack range of about 11 kilometers, still gives the opportunity for ambush and interception.
