From the long -looking moon to the secret of knowing the moon, the "Chang'e -5" R & D team, which is only 33 years old, wrote a new lunar exploration story on the long road of "Chang'e".

Zhang Shu is a software designer of the Long March 5 Lange Rocket Control System. Born in 1989, after graduating from a graduate student, he joined the Long March 5 Lange Rocket Development Team. From just entering the laboratory, it has been in trouble, to the difficulty of launching failure, and now it has become more than now ... The growth of the younger than the growth of young astronauts is accompanied by the pace of Chinese aerospace.

Recently, Zhang Shu tells the story of herself and the Long March 5.

When I first entered the laboratory, I broke the disaster

He becomes the focus of "staring" object

The first experience in entering the laboratory made Zhang Shu remember. He looked at the servo device and light -frightening cable, and touched it for more than 20 minutes.

"This is the first time I have touched these real devices at close range. There is a sense of pride." Zhang Shu said, "I have touched my dream. The next goal, I want to use my software to help it help it One journey. "

However, before he could play his talents, Zhang Shu became the target of the laboratory's focus on "defense". At that time, he wanted to be familiar with scenes and software functions, but accidentally broke the laboratory's electricity. "At that time, a‘ exit ’was selected.‘ Exit ’has an automatic current off -range off -range disconnection process.

In the following two or three months, no matter what Zhang Shu was doing, there would always be a person "staring" next to him. "Even if I compiled a line of code, he had to look at it and asked me what the code was used for this line."

When asked how to look at the "personal bodyguard", Zhang Shu said: "This is also a good thing. Because he is a teacher and a senior, you can ask directly if you have any questions.

In the following two or three years, Zhang Shu took over his ability to work, compiled the software from 20,000 lines to about 60,000 lines, and verified his maturity and reliability by testing.

In Zhang Shu's words, his job is "a mouth of a carrier rocket": "What is its inner state and where is uncomfortable, it must be displayed through my software."

Failure to launch

He and the team gained growth during the weight

On July 2, 2017, the Long March 5 Launar Rockets fell into a failure when performing a scheduled task. When the news was announced, Zhang Shu was at the launch site, and everyone had a sleeping night.

Zhang Shu said frankly that at that time, his first reaction was that he couldn't believe: "There was no sound at the scene. Although there was an air conditioner in the house, it was still dull and unable to breathe."

908 days after the launch of the failure, the entire development team took the weight forward, and finally found out that the failure occurred at the position of the engine and completely repaired.

For more than two years, in addition to reviewing his products simultaneously, Zhang Shu also had a more comprehensive understanding of the Rocket mechanism. Can't ask. "

Zhang Shu said that this is an important experience. "Which pits need to be avoided, which work needs to be arranged in advance, and which risks need to be controlled in advance, which is some important experience I have gained."

Team cooperation to achieve "perfect launch"

He has a dream on his shoulders and is more responsible

On November 24, 2020, the Long March 5 Laurel Rockets successfully sent Chang'e 5 detectors to the monthly transfer track. The industry stated that this is a launch that can almost be called "perfect".

Zhang Shu said that the reason for such a high accuracy is everyone's unity and cooperation. "The engine parameters given by the overall room are very accurate. We control the system involved about 100,000 numbers, about thousands of parameters, checking one by one, and verifying the simulation experiments. I am sure, but I didn't expect to be accurate to this extent. "

The success of Chang'e -5 means that the three steps of the Chinese lunar exploration project have been successfully completed, but the running of Chinese aerospace on the exploration road has not stopped.

For Zhang Shu, who has studied Rockets for many years, the emotion of the Rockets has also changed from natural interest to a responsibility. "Whether it is the current 'long five', or the rocket that will study the greater thrust in the future, I still have that sentence -how big the rocket's load capacity is and how big the Chinese aerospace stage is. This is the responsibility of building a stage for Chinese aerospace. "
