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

Chang Haonan spent one night packing his luggage.

Zhou Li made dumplings overnight.

A northern tradition, dumplings on the car and noodles on the car.

Although I took a plane this time, the principle is still 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 before taking off, Chang Haonan decided to leave early so that he could have an afternoon to understand the situation after arriving in Haojing.

According to his speculation yesterday, it is obvious that the problem that needs to be solved by himself is not just the MA60 model. There is no harm in arriving early to give him more time to prepare.

"Pay attention to your health outside and don't be too tired."

Zhou Li stood at the door and straightened Chang Haonan's clothes, who had already put on his backpack.

Compared with the previous times Chang Haonan returned home in his 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 instead on topics such as paying attention to rest.

And of course find a girlfriend as soon as possible.

At this time, Chang Yuanchao also came forward, holding an envelope in his hand:

"Also, spend money where you should. If it's not enough, just call home and your mother and I will remit the money to you..."

Just from the thickness of the envelope, it can be seen that the money inside is much more than what I took with me when I went out several times before.

"No need to pay, Dad."

Chang Haonan did not answer it, but pushed the envelope back:

"We are paid for our projects, as well as project bonuses and scholarships, which are completely enough for me to spend on myself."

"Hey, take these with you as well."

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

"If you had taken the train, we wouldn't have been able to bring you so much money, but it should be safe to take the plane. If you are poor and have a prosperous life, it is right to bring more money."

"Click——"

Just when Chang Haonan had 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 shyly, with her hands behind her back.

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

Chang Haonan looked at his sister who lowered her head and said nothing and asked.

"Brother, I..."

Chang Jiayao, who had always lowered her head, walked to the door, suddenly stood on tiptoes, stretched out her hands and put a hat on Chang Haonan's head.

"I knitted a woolen hat for you. Well... I had a lot of work last night, so it's a bit ugly, but..."

Chang Haonan touched the top of his head.

Why are you so touched?

So before her sister finished speaking, she reached out and gently rubbed the other person's head.

"Since you gave it to me, I will definitely wear it no matter what."

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

"Don't worry, brother, I will definitely get into flight school this year!"

"Okay, I believe 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 for military and civilian purposes, and this time he went directly to the military aviation side.

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

It is a very rare business jet in China. It was bought in the late 80s and specially used for transporting VIPs.

However, this main function was quickly replaced by the CRJ200 with better performance, so several Challenger 601s were often used to run short and medium-distance charter flights in the system.

However, the decoration and configuration inside the aircraft still retained the previous style, allowing Chang Haonan to have the experience of flying a business jet for the first time in his life.

Among other things, since the cabin pressure of a small business jet can reach close to 1bar (standard atmospheric pressure), while the cabin pressure of an ordinary passenger aircraft is only about 0.7-0.8bar, after getting off the plane at Hokyong Airport, he could hardly feel the pain of the journey at all. Coming fatigue.

Although I didn't care much about this 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 thought in his mind:

"When conditions are met in the future, we will have to do the same in China."

At the same time, a group of people and three vehicles were waiting not far from the parking space.

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

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

Fortunately, when Chang Haonan approached, the thin general stretched out his hand first 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 an indelible contribution to the development of our country's aviation industry, especially in terms of independence. Today, I saw that you are indeed a young talent."

This sudden rainbow fart actually made Chang Haonan himself a bit confused.

To be reasonable, he should praise the other party in turn at this time, but the problem is that Chang Haonan has never heard of the name Huai Guomo before, so there is nothing to brag about.

In the end, I had no choice but to praise the entire Science and Technology Commission:

"No, this is what we as Chinese technicians should do. Furthermore, without the strong support of the Science and Technology Commission, it would be impossible to achieve anything."

After some pleasant greetings, everyone got on the Coaster minibus located in the middle of the motorcade.

"Director Huai, is calling me here this time related to the plane crash in the Alps a few years ago?"

Chang Haonan quickly got to the point.

"Yes, you guessed it accurately."

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

"Although the number of victims in this air crash was small, the impact was very severe."

"Moreover, during the subsequent rescue and disposal process, another A119 helicopter also had an accident at almost the same location. Fortunately, the height of the aircraft was not high, so the death toll was not increased."

"Is it because of the ice?"

Chang Haonan has basically confirmed his guess.

An aircraft accident may also be caused by mechanical failure or human factors.

The fact that two planes crashed at almost the same location can only be caused by weather.

"Before the investigation report is released, it may not be rigorous to say this, but it should be the case. Professor Lin should be more professional in this regard."

Lin Guofan on the other side took over the conversation:

"The winter of 96 to 97 was a record-breaking cold winter, and the water vapor in the Alps was relatively abundant. So I speculate that the meteorological conditions, especially the content of supercooled droplets at near-earth altitudes, may far exceed the previous standards, and even It is possible that the current meteorological monitoring capabilities of many airports will be exceeded, resulting in underestimation of icing risks during route planning."

"Of course, the core problem is that the past certification standards for anti-icing and de-icing capabilities did not consider this situation, and were naturally not prepared to deal with it."

This explanation was technically very reasonable and consistent with Chang Haonan's previous thoughts, so he nodded:

"The kinetic and thermodynamic properties of supercooled large droplets during collision and freezing are indeed different from ordinary water droplets."

"In fact, I personally think that the flight should be grounded under such weather conditions, but if necessary, the MA-60 can also improve its de-icing equipment..."

Before he finished speaking, he was interrupted by Huai Guomo:

"Comrade Xiao Chang, I called you here this time not to continue to improve the MA-60, but because we have received a cooperation application from three parties: France Aerospace, Finmeccanica Group and the European Aviation Safety Agency. "

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

"what?"

Chang Haonan didn't even react for a while:

"The Europeans will lower their profile and come to us...to cooperate?"
