This Shanghai party representative, WeChat nickname was "cow died"?The reason behind it is too romantic ...

Interviewing the party representative Cha Xuelei, plus his WeChat, at first glance, the nickname was "the cow died", which was full of confidence; the note was "New Star", which turned out to be romantic to the vast starry sky.

This romantic and proud, Cha Xuelei, deputy chief designer of the Eighth Hospital of China Aerospace Science and Technology Group, affords.

For nearly 30 years in the space career, he "asked the sky" all the way: from Shenzhou No. 1 to Shenzhou 11, he participated in the design of 11 Shenzhou spacecraft promoting compartment; Tiangong -1 and Tiangong No. 2 to Tianzhou -1 project Design; in 2016, he was transferred to the lunar exploration project and was the technical head of the Shanghai team.

During the epidemic, Cha Xuelei took a marching bed in the office of Minhang, Shanghai, and closed the loop with his aerospace colleagues in a closed -loop and devoted to the preparation of Chang'e -6 and Chang'e VII. Essence

In the party conference venue, Cha Xuerle is also most concerned about issues related to scientific and technological innovation, and talks with other party representatives about "asking the sky" to talk about those things. He said that he often remembered the euphratica tree of the Jiuquan satellite launch base. The euphratica spirit of "immortal, not falling, immortal" inspired a generation of aerospace people to continue inheritance and relay struggle, and also led him and his team in the vast universe True exploration and questioning the sky.

Growing up with Chinese aerospace

Cha Xuelei grew up on the bank of Yangcheng Lake since he was a child. After graduating from the University of Science and Technology in 1994, he wanted to find a job related to scientific research in Shanghai. He did not expect to have a relationship with the Shanghai Aerospace House of Eighth Council, and he entered the aerospace industry with the starry sky.

"I am very lucky. I caught up with the rapid development of China Aerospace and did something in the position of aerospace." Cha Xuerle said that it was 30 years behind China ’s aerospace development. From 1992, my country officially announced the opening of the manned spacecraft, and the successful launch of the Shenzhou No. 1 spacecraft in 1999. In 2003, the Shenzhou 5 sent Yang Liwei to the space. The successful launch of the Tiangong II Space Laboratory ... The Shanghai Manned Aerospace Team left a strong stroke in the History of the Chinese Manned Aerospace Book.

This all the way to pick the stars and the moon, it is spectacular. Looking back, loneliness and bitterness are still tempting. In the past few years of Cha Xuelei, the manned space engineering project was in strict confidentiality, and aerospace technicians were not treated high. At that time, foreign companies gathered and recruited talents. Aerospace people were the focus of headhunting. Under the price of Youkou, many people left, but Cha Xuelei's team was resistant to loneliness and did not leave. "This is the career to keep someone." Cha Xuerle sighed.

The world's round -trip, space out of the cabin, and connection ... these "asking heaven" projects, in the world's mysterious and deep, aerospace experts with their own aura. Cha Xuelei unloaded the "halo": "I want to explain that manned space is a magnificent system project. It is by no means the credit of a certain person or a few people, but the integration of everyone's wisdom. Anyone you see. A space engineering is a combination of gear bite -like unity and cooperation. There are hundreds of units, the efforts and efforts of tens of thousands of people, hundreds of thousands of people. "

He said that in the Shanghai aerospace team, whether it is command, chief or design, quality, and craft personnel, it is an indispensable member of this major national project. Everyone usually performs their duties, and when it is difficult to overcome difficulties, they work closely for the same goal to build a flying dream.

Quality problem "zero tolerance"

The launching ground of the Shenzhou spacecraft is at Jiuquan Base, and it is also the place where Cha Xuelei Aerospace Dream is launched. Every time he stayed in Jiuquan for 3 months. "I counted it, from Shenzhou -1 to Shenzhou 11, plus Tiangong -1 and Tiangong No. 2, I was on the scene in 13 launch, and spent more than 900 days in Jiuquan, and the relationship was deep."

Every time I go to Jiuquan, Cha Xuelei always goes to Dongfeng Martyrs Cemetery. "There is the spirit and soul of Jiuquan. The older generation is developed from the depths of the deserted Gobi to be such a modern Dongfeng town. Experience inherited from generation to generation. "

Cha Xuelei is a receiver and a inheritor. "My master has retired. Now I am standing in front of the team. Our team adheres to a goal, that is, pursuing the ultimate, leaving a hidden danger."

Before Shenzhou 9 was about to launch, a stand -alone machine was found abnormal. According to the regulations, the faulty equipment should be transported back to the Shanghai plant for maintenance, which may take more than 4 months. "The launch time is good, and any link cannot be delayed, but it is difficult to quickly rule out this failure. This situation has never happened." At that time, Cha Xuelei was already a manned space -on project in my country. Deputy Chief Family Planner of Freight Ship System. As the technical person in charge of Shanghai Aerospace at the scene, Cha Xuelei organized the problem to carry out the problem. Finally, he decided to repair and test in Jiuquan, then flew to Beijing, moved to Shanghai, and returned to Jiuquan to replace key components. After three days and three nights of work, the failure was finally ruled out to ensure that the Shenzhou No. 9 spacecraft was successfully launched at the scheduled window period.

"This is the aerospace business, and the heaven products are unimportant. This is a" one hammer buy and sell "." Cha Xuerle said that the quality control and product guarantee work of the manned space engineering is very strict. Be careful. Once a problem occurs, the accumulated 10 years of heart blood and hundreds of millions of funds may be soaked. "Therefore, we must ensure quality, adhere to zero tolerance, do not allow any mistakes, leave a hidden danger, and ensure that the task is successful at all costs." There is a sacred mission in my heart, and there is a lot of pressure on my shoulders. This is the "zero tolerance" that treats quality issues to promote the high -speed development of Chinese aerospace for 30 years. Starting from participating in the design of Shenzhou -1 promoting cabin, until the Shenzhou 11, each spacecraft promoted the body and the cabin of the cabin has poured the effort and wisdom of Cha Xueri, and the changes and changes in each structure of the promotion cabin In the improvement of each technology, he has experienced countless failures and setbacks, and he has been tested.

The leader of "space postman"

In November 2016, Cha Xuelei received a new appointment and was transferred to the deputy chief planner of the Chang'e -5 detector system. This means that he transferred from manned space to the lunar exploration project.

Shanghai Aerospace was also suppressed and was responsible for the design and development of the Chang'e -5 railor. The rail device developed by them is hailed as "space postman". It set up a special space logistics channel during the lunar exploration journey to undertake the transportation task of Chang'e -5 spacecraft between the earth and the moon, but also responsible for the "receiving", "packing", "packing", "packing" in space in space ", Also return to the earth by the lander's 2 kilograms of monthly soil.

Cha Xuelei is the leader of the "Space Postman" team. Focusing on the problem of docking, the team did more than 600 ground simulation tests; more than 700 ground tests were performed around the transfer problem. "Because there is only one chance from heaven, it must be lost." Cha Xuerle said.

In September 2020, more than a month before Chang'e 5 launched, a small failure was found. "This hidden danger may affect the operation of the" space postman ". The time is very tight. Xue Lei said that only one month left for a month. The Shanghai team made a reinforcement treatment of this product and experimented at the launch site to eliminate this hidden danger.

On November 24, 2020, Chang'e 5 successfully launched in Wenchang; three weeks later, Chang'e 5 returned to carry moon samples and successfully returned to the earth. The mission of the "space postman" of Cha Xuelei team also made great achievements.

"Many people ask him: After so many aerospace launch, which is the most memorable one time?" Cha Xuerle always replied: "The first time!"

Shenzhou No. 1 launch

That year he was 28 years old, and Fenghua Zhengmao. He clearly remembers that his master led him and his colleagues, drawing drawings, assembling equipment, and repairing equipment. Finally, a breakthrough from 0 to 1, Shenzhou No. 1 successfully launched. The launching scene of "One Flying Sky" always appeared in his dreams, unforgettable and unforgettable.

Now that he has entered the fifth, he is still the same as that year. He has never stopped the longing and exploration of the vast universe. He regards each "asking the moon" as "the first time".
