Sending "Ask the Sky" into space, her "golden finger" is made like this

□ Chinese Women's Daily All -Media Correspondent Xiao Rui

When the thunderous applause sounded in the test launch hall of Wenchang Aerospace launches in China, Liu Tujie had no response for a moment. She recalled the moment to the Chinese women's reporters. I applauded, I was half a shot. "

At 14:22, July 24, 2022, Beijing time, as the 01 commander shouted the "ignition" password, Liu Tujie, who served as the head of the hair console, stably pressed the red "ignition" button to carry Qi Tian's experimental cabin No. 5 Y Yao three -car rocket was launched on time at the Wenchang Space launcher. In the aerospace industry, the last person who pressed the red buttons was called "golden finger". Liu Tujie, 33, was the first female "golden finger" ushered in the Wenchang launch console.

Become a "golden finger", which is a dream that every aerospace person who works in control systems. From the day when I walked into the Wenchang launch site, to completing this dream, Liu Tujie used it for 7 years.

Concluded aerospace, "I am a half -way monk"

Different from many colleagues who have had aerospace dreams since childhood, Liu Shuojie is actually a "half -way monk" astronaut. She graduated from the University of Defense Technology. The majors and graduate majors are applied mathematics and system science. Due to the excellent mathematical theory and programming performance, Liu Tujie entered a Beijing Institute after graduating in 2013. Soon, he became a technical expert in the institute. If it wasn't for Wenchang's launching ground, Liu Shuojie might become a very good scholar, but a visit to relatives once changed her career and tightly connected her with the aerospace industry.

At that time, Liu Tujie's husband Li Fan worked at Wenchang's launch site. The busy work made Li Fan rarely contact his wife. The most exaggerated time, Liu Tujie did not even turn on the husband's phone call for several days. "He happened to be in the mission period that time. I couldn't contact him for many days. Although he greeted me in advance, I was still a little anxious, and I felt a little 'strange. He didn't have time to connect to the phone? "Recalling that he didn't understand it at the time, Liu Tujie felt a little" funny ".

In 2014, Liu Tujie came to Wenchang to visit relatives for the first time. Her husband said that he took her to see the rocket. Although he usually had not seen a space report on TV, when he really stood under the Rockets, Liu Tujie felt It has never been shocked, "I still remember at that moment, I still remember that the Rockets are too majestic and spectacular!"

At the moment when he looked up under the rocket, his longing for the aerospace industry was deeply rooted in Liu Tujie's heart. After returning to Beijing, she began to apply for work mobilization. Finally, in November 2015, she entered the door of Wenchang's launch site.

At that time, Wenchang's launch site was in a state of "three new": new launch fields, new rockets, new personnel.

As a newcomer, Liu Tujie, the first launch task involved is exactly the first launch task of Wenchang's launch site: the launch of the Long March VII Yao Rocket. At that time, the first job she was assigned was data processing. "Because my major is mathematics, and the data processing is a relatively basic and entry -level post in the control system. This position needs to monitor each parameter. Through these parameters You can get started quickly, understand and understand the entire control system. "

Faced with the new environment and job positions, Liu Shuojie quickly entered the role and exerted his "learning hegemony" characteristics. If you are not familiar with the aerospace field, she has found a lot of job technical materials, one by one, one local study; the theory is almost learned, she ran to the scene, "entangled" the principle of old operating players to learn equipment; after returning home at night She rarely rests, but continue to work overtime and summarize her experience.

7 years of sharpening, overcome three difficulties

Over the years, more and more women have made outstanding contributions in the aerospace field. From the astronauts Liu Yang, Wang Yaping, to Liu Tujie and her female colleagues, they have glowed and lived in the aerospace field, and they have used their own. The story shows women's power. In Liu Shuojie's view, every chance of women in the field of aerospace is not easy. She told reporters: "If women astronauts want to be seen, they need to cross three difficulties."

The first difficulty is the physiological barrier. "The aerospace field is originally a place where there are more men and women. In our Wenchang launch site, the proportion of men and women exceeds 20: 1. Women will be arranged to be arranged because of physical strength and physiology. Relative to the "relaxed" post, you will not let you pick up the beam. "Liu Tujie's character in the bones of Hunan, let her decide to break through the physiological level.

Up to now, Wenchang's launcher has implemented 18 launch mission. Liu Tujie has participated in the guarantee and witnessed 17 times. It can be said that Liu Tujie grew up with Wenchang's launch site. The only launch she missed was on April 20, 2017, the Long March 7 Yaozo Two Rockets equipped with Tianzhou -1 freight ships launched. On that day, Liu Tujie's son An An fell to the ground. No. baby ".

After the child was born, Liu Tujie quickly put into work again. Before maternity leave, she began the research on the subject.

After the maternity leave, she rolled to the front -end position of the hair control. When this post performs tasks, she needs to climb the 16 -story umbilical cord tower (a fixed or back -down type of fixed or back -up type of pipeline pipeline pipelines, etc. Tower), after the umbilical cord tower reaches the 12th floor, it is almost necessary to climb up and use the state to climb up, which is not easy for most people. At that time, Liu Tujie, who weighed 160 pounds, under the pressure of a large weight, twice the upper and lower umbilical cord tower twice a day made her knees severe accumulation, but Liu Tujie did not shout a pain, and there was no absence. Once a task. Every night when she returns home, the infrared therapy and plaster became her essential. After getting up the next day, she continued to conquer the 16 -story umbilical cord tower against the plaster. The second difficulty is the psychological barrier. This level is from the inside to the outside. From the most basic data processing to becoming a "golden finger", Liu Tujie has also had self -doubts. In the face of difficulties, Liu Tujie said that he had thought about giving up countless times, "but sometimes after giving up Unwilling, think about it, still pick up your dreams and continue. "

Many people asked Liu Tujie, "You can't climb the (umbilical cord) tower, why do you still need to climb? You can't get in this cabin, or even if you?" In the face of such questions, Liu Tujie gave the answer. : "If I find a reason to retreat in the face of every difficulty, I can't prove that what others can do can do it, and I have no chance to enter everyone's vision. More people will think the" comrade's comrade , Jiaojiao's atmosphere, I will wear this kind of colored glasses. I want to prove that I can, there is no difference between me and gay men. "

After crossing the first two levels, do you have the opportunity to become a "golden finger"? Liu Tujie told reporters: "Overcoming the first two difficulties, it can only prove that you are not different from others, and it is not enough to take the position of‘ golden fingers ’. You have to give you a stronger persuasion."

During the 7 years after Liu Shuojie came to Wenchang's launch site, she took almost every position of the control system, from data analysis and application, processing, to familiarity with the principles of rockets. For the person in charge.

In addition to busy work, Liu Shuojie also used all time to invest in scientific research. "In the process of experience in various positions, I set a small goal for myself, that is, I have to write a paper or do a study in one position in each round. Liu Tujie published more than 20 papers in the core journal, and put forward his own opinions on the basic theory of each position and the improvement of work methods.

The grinding for 7 years has made Liu Shuojie from the original "Aerospace Gate" to become a technology of control systems, and also made her get closer and closer to the dream of the "golden finger".

Objective: From "Gold Finger" to Full System NO.1

Knowing that I was selected as the "Golden Finger" that I was selected as the launch of the test compartment, it was the fall of 2021. At that time, Liu Tujie's first reaction was "both an accident and no accident". Not surprisingly because after these 7 years of hard work, I feel that I am ready. "

In the eyes of ordinary people, the movement of the "Golden Finger" finally pressed the button was handsome, but behind this small movement, it was by no means just listening to the 01 commander "ignition" password.

As the "nerve center" of the rocket control system, the hair console has more than a hundred buttons. Each button represents a control instruction. There are nearly 300 parameters and status lights on the four displays. Each parameter represents different front ends. The state of the device. This not only requires the "golden finger" to have a finger to the entire rocket hair test process, but also requires a global thinking.

In order to meet the needs of the intersection of the test compartment and the space station combination, the rocket launch selected the "zero window" launch (referring to the rocket launch time and the scheduled ignition time deviation of more than 1 second). "Zero window" launch. "The" zero window 'launch means that the launch time needs to be calculated in advance, and the rocket ignitions the ignition of the rocket. This puts forward higher requirements for the ability of' golden finger ' Related emergency response situations can be found to get more time to correct each second in advance, "Liu Tujie explained.

Liu Tujie said: "The biggest challenge for this task to me is to quickly identify abnormal parameters." In layman's terms, it is to be able to find problems quickly. In the case of high pressure, the first response that encounters problems may be the feeling of being stunned and "blindfolding". This is a physiological reaction of human instinct and it is difficult to avoid. However, in the face of the rocket launch mission, Liu Shuojie needs to overcome all physiological reactions. When the abnormal parameters appear, you must directly enter the rational processing system and think about "what should I do".

Such calmness is not a few days of practice, but it needs to be studied over time. Liu Tujie and her colleagues upheld such a sentence at work: I would rather think that I hadn't met, I couldn't meet. "During the mission preparation stage, we will make presets and scores on all the possible situations that each node may occur, and finally form hundreds of thousands of plans to ensure that when any abnormal situation occurs, I can quickly get from my mind from my mind. Solution to all the problems. "

In the early morning of July 24, about 14 hours before the launch, Liu Tujie came to the test launch hall in the night in the night to make the final preparation for the launch task.

At 14:21 on July 24th, the last minute before the launch mission. With the "allowable ignition" instructions, the launch entered the final countdown: "50 seconds ... 40 seconds ... 30 seconds ... 20 seconds ... 10, 9, 7, 6, 5, 4, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 2. 1, ignition! "Under the instructions of the 01 commander Liao Guorui, Liu Tujie pressed the red" ignition "button, which was called the" Fat Five "long five -B rocket to pull up the ground, the ground roaring, Liu Tuosa Jie's face was calm and his voice was calm, but when we looked back at the picture of her pressing the button again, she would find that her hand trembled slightly in the close -up lens.

About 495 seconds later, asked the Tiangan experimental compartment and the Rockets successfully separated and entered the predetermined track. There was a thunderous applause in the test hall. Liu Tujie, who did not hesitate to hesitate for a second before he was hesitant. Get up. The colleague Wang Yumeng, who was sitting around her, patted her hand gently, and told her, "You are great!"

At the same time, his son An An introduced to the teachers and friends in the kindergarten in the kindergarten, "My mother is the" golden finger "that launch the rocket!"

Once, An An didn't have much time to accompany him, and said to Liu Tujie, "You are not a good mother", which made Liu Tujie sad. But on the evening of the day after the launch of the sky was successful, when Liu Tujie returned home to see An An, her son gave her a big hug. "Mom, you are the best mother in the world!" At that moment, Liu Tujie felt Very proud.

The launching task of the test cabin was successful, but Liu Tujie did not have time to rest. She was immediately put in the Dream Tian Temple launch mission three months later. She revealed to reporters, "My next goal is to become the 01 commander of the control system as soon as possible, and complete the transformation from the female number 1 of the" Golden Finger "to the full system NO.1."

Living in Hainan, Liu Shuojie likes coconut trees everywhere on the roadside. "There are many typhoons in Hainan. After the storm, the coconut trees are often blown to the ground, but it will not grow towards the crooked direction, but fall down. In the place, continue to raise his head to survive in the sun. "Liu Tujie hopes that all women who love the aerospace industry can be strong like coconut trees.
