The modification of manned spacecraft launch vehicles is rapid.
It started in July when it received the mission to launch a manned spacecraft.
It will take no more than three months to complete the transformation of the entire rocket launch system.
The ability to complete the rocket modification work so quickly is not only due to the efforts of many scientific researchers at the Rocket Research Institute.
It would also be inseparable from the great help of many colleagues 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 entire manned spacecraft system, escape tower system and fault detection and processing system are integrated, it will soon enter the simulation test stage.
Because the flight control center for manned spaceflight is located in Beidu. Therefore, the first full-system simulation experiment also needs to be conducted in Beidu.
"How are the preparations for the rocket?"
Although there was less than half a day before he had to go to the flight control building in Beidu to conduct simulation experiments, Zhang Xingyang still took some time to ask about the situation of the manned space launch vehicle.
"Everything is ready. I just took someone to check it again."
Geng Bo looked Zhang Xingyang's outfit up and down and then replied.
"There won't be any problems, so don't worry."
"By the way, don't forget to ask Qiao Yang to keep an eye on the supersonic wind tunnel."
Zhang Xingyang reminded him while smoothing the wrinkles on his clothes with his hands.
"Has the supersonic wind tunnel started?"
Geng Bo was a little surprised, but he still agreed:
"I will tell him."
"Construction has not started yet, but they have given a few preliminary locations, and he needs to go with them."
After smoothing out the last wrinkles in his clothes, Zhang Xingyang raised his head and asked Geng Bo:
"Is there anything else wrong?"
Although he didn’t know why Zhang Xingyang, who had never paid much attention to dressing up, suddenly asked about his clothing, Geng Bo still looked at it carefully and said:
"It's very smooth. Are you going to meet someone?"
"Going to see a senior for the last time."
Zhang Xingyang turned around and left, leaving only these words in the air.
The wide body of the Airbus landed slowly at Beidu's international airport.
Zhang Xingyang did not notify anyone when he came to Beidu this time, but came alone in advance.
Because this matter cannot be regarded as work, he actually paid for the air ticket himself.
Sitting in the taxi, there were 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!"
"do not forget!"
"do not forget!"
In Beidu Cancer Hospital, an equally ordinary old man lay on an ordinary bed.
The non-aerospace staff standing next to the bed found it difficult to understand the conversation between the two.
But Chen Zhongyan’s students around him and people working within the aerospace system all knew what he was talking about.
Chen Zhongyan's wish at this time was nothing more than manned space flight.
Suddenly, the old man seemed to have suddenly recovered, his face became rosy, and he seemed much more energetic.
His hands were even strong enough to support him to sit higher.
Seeing the old man in such a situation, everyone present basically had no happy reaction.
Several women who were particularly close to each other almost couldn't help but cry.
Because everyone knows that if the old man suddenly looks better, there can only be one situation, and that is that his life has come to an end and there is a return of glory!
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:
"Thank you for taking the time to visit me, an old man, when you are 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 hazyness in his eyes.
People like Chen Zhongyan who can look down on life and death are definitely rare in the world.
Even in Zhang Xingyang's previous era, he was still in the minority.
"You are half of my teacher, I can't help but come."
Because many people present did not have the corresponding authority to know about manned spaceflight, Zhang Xingyang did not reveal his true purpose.
At this time, Chen Zhongyan did not continue talking to Zhang Xingyang, but looked at his child.
Chen Zhongyan's wife passed away early, and his few relatives only had two children, a boy and a girl.
"Wenhua, Wenli, after I leave, you two must work hard and live a good life!"
"As for my posthumous affairs, the country will naturally be responsible for it, so you two don't have to worry about it."
"You guys should go out first. I have something I want to talk to Zhang Xingyang about."
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 for the full system simulation of manned spaceflight?"
The moment Zhang Xingyang walked into the ward, Chen Zhongyan thought that he was definitely not here specifically to see him.
Because with how busy he is, if he doesn't have something special to do, he definitely won't make a special trip to Beidu.
"Yes, the modification work of our Hongyan rocket for the manned spacecraft has been completed last week."
"I came here this time just to communicate with the flight control center."
Zhang Xingyang simply admitted that the real purpose of his trip to Beidu was not just to see Chen Zhongyan for the last time.
"How's it going? Is the simulation experiment reliable?"
Although he is no longer responsible for any space missions, Chen Zhongyan still couldn't help but ask.
"According to the computer simulation experiments we conducted within the institute, the success rate can reach 99.98%."
Zhang Xingyang did not hide too much and satisfied Chen Zhongyan's curiosity.
"The main reason is that there are some data errors that cannot be eliminated."
"It's a pity that I can't see the moment when our own manned spacecraft enters space!"
Chen Zhongyan glanced out the window with a little regret.
Although it was already October, 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 have no way of seeing the day when a manned spacecraft enters space."
"But, Xingyang, you can see it."
"Please, after our manned space flight is successful, don't forget to burn the report to me!"
