Chang Haonan spent the night packing his luggage.

And Zhou Li made dumplings overnight.

The tradition of the north, getting on the dumplings and getting off the noodles.

Although I was on a plane this time, the principle was the same.

The next morning, the three of them had breakfast at dawn—

Although the plane arranged by the Science and Technology Commission would obviously wait for him to board the plane before taking off, Chang Haonan still decided to leave early, so that he would have an afternoon to understand the situation after arriving in Hojing.

According to his speculation yesterday, it is obviously not just the problem of the MA60 model that needs to be solved by himself, and it is no harm to have more time to prepare as soon as possible.

"Pay attention to your body outside, don't get too tired."

Zhou Li stood at the door and straightened Chang Haonan, who had already put on his bag.

Compared with the first few times he went home in Chang Haonan's memory, it may be because he has proven himself now, so his parents' instructions have nothing to do with study and work, and the focus is on topics such as paying attention to rest.

And, of course, finding a girlfriend as soon as possible.

At this time, Changyuan Chao also stepped forward, holding an envelope in his hand:

"Also, spend where you need to spend money, if it's not enough, call home again, and your mother and I will send you money......"

Just by the thickness of the envelope, you can tell that there is much more money in it than it has taken with you when you go out the previous times.

"No more money, Dad."

Chang Haonan didn't answer, but pushed the envelope back:

"We have a salary for doing projects, as well as project bonuses and scholarships, which are completely enough for me to spend."

"Eh, yours, bring these with you."

In the end, Chang Haonan still didn't resist his father, and the latter stuffed the envelope into the inner pocket of his coat:

"If you take the train, we can't bring you so much money, but it should be safe to take the plane, and the poor are rich, so it's right to bring more money."

"Click-"

Just when Chang Haonan had already picked up his travel bag and was about to go out, the door of the bedroom on the other side suddenly opened.

Chang Jiayao walked out of the room a little wryly, with her hands behind her back.

"Jia Yao, I'm leaving, you study hard at home, don't worry your parents too much."

Chang Haonan looked at his sister who bowed his head and was silent.

"Brother, I'm ......"

Chang Jiayao, who had been keeping her head down, walked to the door, suddenly stood on tiptoe, stretched out her hands and put a hat on Chang Haonan's head.

"I knitted you a woolen hat, huh...... Because I was in a lot of work last night, it was a bit ugly, but ......"

Chang Haonan touched the top of his head.

What's the deal with being a little moved?

So without waiting for my sister to finish speaking, she reached out and gently rubbed the top of the other party's head.

"Since you sent it, I must wear it anyway."

Chang Jiayao raised her head after hearing this, and suddenly expressed her determination to Chang Haonan:

"Brother, don't worry, I will definitely be admitted to the flight school this year!"

"Okay, I trust you."

……

After saying goodbye to his family, Chang Haonan took a taxi and went straight to the airport.

Sanyan Airport is a dual-use airport, and this time he went directly to the side of the military aviation.

The plane that came to pick him up was also a Challenger 601 belonging to the Air Force United Aviation.

A kind of business jet that is quite rare in China was bought back at the end of the 80s and specially used for the transportation of dignitaries.

However, this main function was soon replaced by the better-performing CRJ200, and several Challenger 601s were often used for short- and medium-haul charter flights within the system.

However, the decoration and configuration in the plane still retain the previous style, which also allows Chang Haonan to have the experience of flying a business jet for the first time in his life.

Not to mention, because the cabin pressure of a small business jet can reach close to 1 bar (standard atmosphere), while the cabin of an ordinary passenger plane is only about 0.7-0.8 bar, he almost does not feel the fatigue caused by the journey after getting off the plane at Hokyo Airport.

Although I didn't care much about this before because I was young, there is still a big gap between being able to hold on and not feeling it.

"MD, this thing is good......"

Before Chang Haonan walked down the gangway, he looked back at the small plane, and at the same time thought in his heart:

"When there are conditions in the future, I have to make one in China."

At the same time, a group of people and three cars were already waiting not far from the parking stand.

Among the people who came to pick up the plane, in addition to the expected Yi Yuanhe and Zhou Yonghang, there were also Liang Shaoxiu, who rushed from Factory 182 and participated in the formulation of airworthiness standards for anti-icing capability and related test flights, Lin Guofan and Zhu Lan from Jinzhou University, and a lieutenant general, who Chang Haonan had never seen before.

Judging from the position, he should be the leader in this team.

Fortunately, when Chang Haonan approached, the thin general took the lead in reaching out and introduced his identity:

"My name is Huai Guomo, deputy director of the Commission of Science, Technology and Industry for National Defense, in charge of foreign technical cooperation."

"I have heard Director Ding mention your name many times before, saying that Comrade Chang Haonan has made indelible contributions to the development of China's aviation industry, especially in terms of independence.

This sudden rainbow fart turned Chang Haonan himself a little bit away.

To be reasonable, he should brag the other party in turn at this time, but the problem is that Chang Haonan really hadn't heard of the name Huai Guomo before, and he couldn't boast about it.

In the end, I had to choose to tout the entire Science and Technology Commission:

"Where, this is what we should do as Chinese technicians, and besides, if there is no strong support from the Science and Technology Commission, it is impossible to make any achievements."

After a hearty greeting, everyone got into the Coaster minibus in the middle of the convoy.

"Director Huai, did you call me over this time because of the air crash in the Alps years ago?"

Chang Haonan quickly got to the point.

"That's right, you guessed it right."

Huai Guomo, who was sitting in the front row, turned around and replied approvingly:

"Although the number of victims in this air crash is small, the impact is very bad."

"Moreover, in the follow-up rescue and disposal process, there was also an A119 helicopter that had an accident at almost the same place, but fortunately, the altitude of the aircraft was not high, and there was no increase in the number of fatalities."

"Is it because it's freezing?"

Chang Haonan has basically confirmed his guess.

An accident with an airplane can also be caused by mechanical failure or human factors.

The accident of the two planes in almost the same position can only be due to the weather.

"Before the investigation report was issued, it may not be too rigorous to say this, but it should be so, and Professor Lin should be more professional in this regard."

Lin Guofan on the other side took over the conversation:

"The winter of '96-'97 was a record-breaking winter, and the Alps were rich in moisture. Therefore, I speculate that the meteorological conditions, especially the supercooled droplet content at near-Earth altitude, may far exceed the previous regulations, and may even exceed the current meteorological monitoring capabilities of many airports, resulting in an underestimation of the risk of icing in route planning. ”

"Of course, the core problem is that this situation has not been considered in the past certification standards for anti-icing capabilities, and it is naturally unprepared to deal with it."

This explanation is technically very reasonable, and it is also in line with Chang Haonan's previous thoughts, so he nodded:

"The dynamics and thermodynamics of supercooled droplets during collision and icing are indeed different from those of ordinary water droplets."

"Actually, I personally think that this kind of meteorological conditions should be grounded, but if the MA60 needs it, it can also improve the de-icing equipment......"

Before he could finish his words, he was interrupted by Huai Guomo:

"Comrade Xiao Chang, I called you here this time, not to continue to improve the MA60, but we have received a joint application for cooperation from the French Aerospace Company, the Finmecanica Group and the European Aviation Safety Agency."

"Oh, judging from the wording of their letter, it can also be directly understood as a request for help from us."

"Huh?"

Chang Haonan didn't even react for a while:

"Europeans will come to us with a lower profile...... Want to cooperate? ”
