The retrofitting of manned spacecraft launch vehicles is fast.

Since July, it has been entrusted with the launch of a manned spacecraft.

To the entire rocket launch system, to complete the renovation work, no more than three months.

The ability to complete the transformation of the rocket so quickly is not only due to the efforts of many scientific researchers of the Rocket Research Institute.

It is also inseparable from the help of many peers of the Chang-2F launch vehicle, without their help.

It is difficult for the Rocket Research Institute to figure out the many technical difficulties on the manned spacecraft so quickly.

After the integration of the entire manned spacecraft system, the escape tower system and the fault detection and handling system, it will also enter the simulation test stage.

Because the flight control center of manned spaceflight is located in the northern capital. Therefore, the first system-wide simulation experiment also needs to be carried out in Beidu.

"How's the rocket getting ready?"

Although there was less than half a day to go, he was going to the flight control building in Beidu to conduct simulation experiments, Zhang Xingyang still found a little time to ask about the situation of the manned space launch vehicle.

"It's all ready, I just took someone to check it again."

Geng Bo replied after looking Zhang Xingyang's outfit up and down.

"There won't be any problems, so don't worry."

"By the way, don't forget to let Qiao Yang keep an eye on the supersonic wind tunnel."

Zhang Xingyang reminded while brushing the folds on his clothes with his hands.

"Has the supersonic wind tunnel started?"

Geng Bo was a little surprised, but he still agreed:

"I'll tell him."

"The construction hasn't started yet, but there are a few preliminary site locations over there, and he needs to follow along."

After flattening the last wrinkle of his clothes, Zhang Xingyang raised his head and asked Geng Bo:

"Is there anything else that is uneven?"

Although I don't know why Zhang Xingyang, who has never paid much attention to dressing up, suddenly asked about his dress, Geng Bo still looked at it seriously and said:

"It's very flat, are you going to meet someone?"

"Go and see a senior one last time."

Zhang Xingyang turned around and left, only to leave such a sentence in the air.

The wide fuselage of the Airbus aircraft slowly landed on the international airport in the northern capital.

Zhang Xingyang came to the north this time without notifying anyone, but came alone in advance.

Because this thing can't be considered work, in fact, even the plane ticket is his own money.

Sitting in a taxi, there are more high-rise buildings outside the window than when Zhang Xingyang came two years ago.

However, Zhang Xingyang's mood sank little by little as the distance between the taxi and the destination got closer and closer

——

"Xingyang!"

"Don't forget!"

"Don't forget!"

In the Beidu Cancer Hospital, on an ordinary bed, there was an equally ordinary old man.

The non-aerospace workers standing next to the bed had a hard time understanding the content of the chat between the two.

But the students around him, as well as those who work within the space system, know what he says.

Chen Zhongyan's wish at this time was that there was nothing else but manned spaceflight.

Suddenly, the old man seemed to have suddenly recovered, his face became ruddy, and his whole person seemed much more energetic.

Your hands can even have the strength to support yourself and sit a little higher.

Seeing the old man in such a situation, everyone present basically did not have a happy reaction.

Several women who are particularly close to each other even almost couldn't hold back their tears.

Because everyone understands that the old man suddenly looks better, there can only be one situation, that is, life has come to an end, and there is a glow!

Ignoring the ugly faces of everyone in the ward.

Chen Zhongyan slowly took off the oxygen mask on his face, took a deep breath, and said to the crowd around the bed:

"It's hard for everyone to take time out to come and see me as an old man when they're so busy."

"Especially you, Xingyang."

"I didn't expect you to come."

Although Chen Zhongyan's eyes were smiling when he said this.

But Zhang Xingyang couldn't smile at all, and there was even a hint of haze in his eyes.

A person like Chen Zhongyan who can look down on life and death is definitely rare in the world.

Even in the era before Zhang Xingyang, it was a minority.

"You're half my teacher, I can't help but come."

Because many of the people present did not have the corresponding authority to know about manned spaceflight, Zhang Xingyang did not say his true purpose.

At this time, Chen Zhongyan did not continue to talk to Zhang Xingyang, but looked at his child.

Chen Zhongyan's wife left early, and the few relatives only have two children, a man and a girl.

"Wen Hua, Wen Li, after I leave, you two have to work hard and live well!"

"As for my afterlife, the state is naturally responsible, so you two don't have to worry about it."

"You guys go out first, I still want to talk to Zhang Xingyang about something."

After Chen Zhongyan's children, medical workers and students left.

After Chen Zhongyan asked Zhang Xingyang to close the door of the ward, he asked:

"Xingyang, are you here this time for the whole system simulation of manned spaceflight?"

The moment Zhang Xingyang walked into the ward, Chen Zhongyan thought that he definitely didn't come to see him.

Because with his busyness, if he didn't have special things to do, he would definitely not make a special trip to the northern capital.

"Yes, last week's modification of our Hongyan rocket for the manned spacecraft has been completed."

"I came here this time to dock with the flight control center."

Zhang Xingyang simply admitted the real purpose of his trip to the Northern Capital, not just to see Chen Zhongyan for the last time.

"Well, are you sure about the simulation?"

Although he is no longer in charge of any space missions, Chen Zhongyan still couldn't help but ask.

"According to the computer simulation experiments we have done in the institute, the success rate can reach 99.98%."

Zhang Xingyang didn't hide it too much, satisfying Chen Zhongyan's curiosity.

"The main reason is that there is a part of the data error, which cannot be eliminated all the time."

"It's a pity that I can't see the moment when our own manned spacecraft goes into space!"

Chen Zhongyan glanced out the window with a little regret.

Although it was already October at this time, the leaves on the trees outside the window were still lush.

At this time, Zhang Xingyang didn't know what to say to comfort this old man who had come to the end of his life and was still thinking about the aerospace industry.

"Although I didn't have the means to see with my own eyes the day the manned spacecraft went into space."

"But, Xingyang, you can see it."

"Please also ask you, after the success of our manned spaceflight, don't forget to burn the report to me!"
