What are we, the post-90s generation, doing? I believe there are many answers to this question. But if I say that those born in the 1990s are already engineers at the satellite launch center and commander of the cryogenic power system at the launch site, you will be surprised. After all, in our impression, anyone who can become such an aerospace expert must have gray hair on his temples. It can be said that such a young expert is rare. It is really rare. But you heard it right, this rocket expert born in the 1990s is Yu Xinchen, a big boy born in the 1990s. He is the star we should chase. Despite his young age, he has successfully participated in more than 60 rocket launches

Although he is young, this 90-year-old boy has successfully participated in more than 60 rocket launches and more than 80 satellites. launch mission. Among them are the well-known major launch missions such as Chang'e-3, Chang'e-5 re-entry flight test, Fengyun-4, Beidou-3 and so on. The well-deserved technological star of Xichang Launch Site’s power system. He performed well while at Tsinghua University, but after graduation he chose to stay in Shangougou.

Yu Xinchen was born in Woyang County, Bozhou City, and has excelled in studies since he was a child. In 2007, he was admitted to Tsinghua University in advance with excellent results. While in college, Yu Xinchen was as outstanding as ever. Not only did he serve as the Life Minister of the Student Union, but he also participated in the centenary celebration of Tsinghua University as a host.

Yu Xinchen majored in aerospace knowledge at Tsinghua University. When he was assigned for graduation, Yu Xinchen did not be tempted by the high wages outside, nor did he choose to continue his graduate studies. Instead, he resolutely came to the front line of the Xichang launch site deep in the Daliang Mountains. In his eyes, the motherland's aerospace industry is at a critical period, and he happens to have learned this knowledge, so he should contribute what he has learned in the past four years of college to the motherland's aerospace industry. This is the star we should chase, the true backbone of the country. After graduating from Tsinghua University, he worked as an elevator operator in a mountain valley

Yu Xinchen, who came to the Xichang Satellite Launch Center with enthusiasm, did not participate in rocket launches as he initially imagined. Instead, he became an elevator operator. His daily job was to control the elevator to transport people going up and down the tower to the corresponding floors. I believe that most people can do this job. Such a gap did not discourage Yu Xinchen, but instead worked harder. A few months later, Yu Xinchen was assigned to the rocket's conventional power system and became an ordinary job operator.

Step by step, although this job is much improved compared to that of an elevator operator, it is only some technical operations and has little relevance to theoretical majors. But Yu Xinchen didn't think so in his heart. In his eyes, it is necessary to master these basic operations, which will help him grasp his technical status when he becomes a commander in the future. With his hard work, Yu Xinchen soon became fully qualified for the position and served as the professional person in charge of the system.

Later, due to work needs, he was again assigned to serve as the operator of the rocket cryogenic power system. The cryogenic power system involves the filling of liquid hydrogen and liquid oxygen cryogenic propellants. The cryogenic propellant has an extremely low temperature and is flammable and explosive. The testing process is complex and cumbersome. Before launch, it requires continuous high concentration and high-intensity work for more than 8 hours. He I stayed in this system for 6 years. It was in this position that Yu Xinchen developed the ability of "listening to leak detection" and eliminated launch failures many times. And because Yu Xinchen often checked the status of each joint against the drawings, so much so that he could tell the location and details of the joints with his eyes closed, Yu Xinchen was also called a "living drawing" by his colleagues. Yu Xinchen troubleshooted and made outstanding contributions to the successful launch of the mission

In the early morning of August 25, 2018, Yu Xinchen, who had been working continuously for 8 hours at the command seat, suddenly discovered that the sensor showed that the rocket was on the third stage The outlet pressure of key components of the engine is higher than the index requirements and continues to rise. This component directly affects the normal startup and shutdown of the three-stage engine. If the fault cannot be eliminated within 1 hour, the mission will most likely be terminated, and the original launch time of the two Beidou-3 satellites will be delayed by at least 7 days. , if you risk the launch, it is very likely that the three-stage rocket will not work and the satellite will not be able to enter orbit.

In an emergency situation, technicians gathered together to discuss troubleshooting plans. After trying the first solution, the situation did not improve. After trying the second solution, the pressure value continued to rise close to the upper limit of the safe value, and the situation worsened! At this time, there were still 5 minutes left until the end of the allowed troubleshooting time. Time passed by minute by second, and the command hall was silent. At this time, based on the engineering characteristics of the component, Yu Xinchen believed that increasing the inlet gas pressure of the component would reduce its outlet gas pressure. He calmly and decisively issued the command to increase the inlet gas pressure. This parameter dropped rapidly within 1 minute. to within the range of index requirements. In this way, with only two minutes left before the allowed troubleshooting time, Yu Xinchen successfully commanded the system personnel to eliminate the fault that was related to the success of the mission and made outstanding contributions to the success of the mission. The tears of astronauts

These pillars of the country in the eyes of us ordinary people are actually children. For them, there are no holidays 365 days a year, except for studying hard in the mountains and valleys. , wanting to go home to see your parents has almost become a luxury.

For Yu Xinchen, since he started working, going home to live with his parents for a week every year has become the happiest thing for him. In order not to worry his parents, Yu Xinchen hid a lot of dangerous work, so we can To have such a wonderful life now, I really want to thank these scientific researchers. They have worked really hard. Yu Xinchen's future plans

A soldier who doesn't want to be a general is not a good soldier. In the same way, a space system commander who doesn't want to be "Commander 01" is not a good commander.

As the youngest sub-system commander of the Xichang Satellite Launch Center, he also has his own "small goals" for the future. That is, I hope to have the opportunity to become "01 Commander" in the future. ?01? Equivalent to the command center of the launch site, it is the big steward of the command center. Being able to hold this position is not only an affirmation of ability, but also an honor.

I believe that Yu Xinchen, a big boy born in the 1990s, will definitely achieve his goal. Likewise, as those born in the 90s, we must also work hard, for our motherland and ourselves, let’s work hard!
