At 14:22 on July 24th, Wenchang Aerospace launched in Hainan, and the Chinese Space Station asked the Tiangtian Experimental Crystal to the Sea of ​​Star. At the launch site, the most exciting moment was that with the commander, the staff pressed the red ignition button. The person who pressed the ignition button was called "golden finger". For this light, a Hunan girl has been preparing for 7 years.

"Ignition!" With the launch of the launch of the test compartment "01" commander to ignite the order, the engineer Liu Tujie accurately pressed the red ignition button -although this action has been practiced hundreds of times, you can see the Long March on the big screen until the big screen is on the big screen She was a little relaxed when she broke through the picture of the sky that broke through the sky. At 14:22 on July 24th, the Long March 5 Yao Three Rockets with the Tiantian Experimental Cels was successfully launched at the Wenchang launcher in Hainan, and a new member of the China Space Station added. This time, the first time the Wenchang launch site was completed by female technology workers. And she is Xiangmei from Shaoyang.

It's not just as simple as your fingers move

"Seven years of hard work, in exchange for the moment of ignition, it is very satisfied, good!" In an interview with reporters, Liu Tujie was still excited.

The ignition is the last operation of the rocket in the launch site, and the last level before taking off. The Long March 5 rocket adopts a manual ignition method, which is completed by the control system hair console position. The post is named "Golden Finger" because it is necessary to press the ignition button.

Before the "01" commander issued a ignition password, Liu Tujie stared at the screen, always paying attention to the parameter state to ensure that the ignition conditions were met.

"‘ Golden Finger ’ -Press is the most important buttons.” Liu Tujie said that at the position of the hair console, everyone paid attention to the move of the ignition button. This action is very handsome, but it is by no means just listening to the "01" ignition password. As the "nerve center" of the rocket control system, the hair console is as many as hundreds of buttons. Each button represents a instruction. The nearly 300 parameters and status lights displayed on the four -sided screen are associated with the equipment of the rocket front end. These all require the person in charge of the post to have the overall thinking of the entire set of measurement processes.

In addition, in order to meet the needs of the intersection of the Tiantian experimental compartment and the space station combination, this time the rocket launch, the zero window launch (referring to the rocket launch time and the scheduled ignition time deviation of the ignition cannot exceed 1 second). This means that the launch time needs to be calculated in advance, and the rocket ignitions the ignition of the rocket in seconds without allowing any delays and changes; it also means that the ability and quality of the person in charge of the hair console is higher.

"Zero window launch means that I want to be more familiar with the relevant emergency response situation. Every second in advance to find abnormalities in advance, I can get more time to correct it for the launch window." Liu Tujie said, "And, in the zero window launch, launch Under the requirements of other types of rockets, compared with the automatic ignition process of other types of rockets, the manual ignition of the hair console can more flexibly control the rocket pre -shooting process, and it is more in line with the time accuracy required for the launch. "

Liu Shuojie organized testing at the hair console

Conquer two hundred steps against plaster

The "gold" amount of "golden fingers" is prepared at 7 years. In the Wenchang launch site, the proportion of men and women exceeds 20: 1. "There are still more men in aerospace industry than women, especially rocket launch. Many posts are more popular." Yu Peng, who has served as the commander of the control system, believes that it is not easy for Liu Tujie to grow into a "golden finger".

To grow rapidly in launch positions, female workers need to work more effort.

"Every post, every setting goal, I believe that I can do better." Recalling my growth experience, Liu Tujie wrote lightly.

In the winter of 2015, Liu Shuojie came to Wenchang's launching ground. In 7 years, he executed all the tasks of Wenchang's launcher. She grew up in every post into a person in charge, and finally became a "golden finger".

Liu Shuojie is judging data

Among them, a considerable part of work has higher physical strength for women, but she is not timid. In order to pull the cable, Liu Shuojie exercise every day to enhance the core force; in order to complete the operation of the high -altitude rod, she is afraid that she will go to the playground to try the roller coaster and pirate ship; In Huai Liujia, she was also carefully found in hundreds of data monitoring. She found abnormal corners of the rocket servo mechanism in real time, and assisted in finding the cause, solving the failure in time, preventing more serious engine damage ...

After Dinggang's console, the first thing Liu Tujie had to do was to study the "nerve center" of the hair console. She designed pictures in the rocket, carefully analyzed the changes caused by the instructions, and which parameter abnormalities would be caused after the movement was abnormal. She and the rocket designer jointly study each circuit, classify the parameters of the current and voltage of some components, record it in detail with the notebook, and make the knowledge points of each category into a small card. Don't forget to take it out.

Physical strength is another difficulty. When performing the task, you need to climb the 16 -storey umbilical cord tower (for the fixed or rear pipe tower for supporting test cables, adding pipe pipes, etc.). Therefore, every day, Liu Shuojie has to go up and down the umbilical cord tower twice. Long -term climbing stairs gave her knees with effusion, and every time she went upstairs, she was uncomfortable. The infrared therapy instrument and thermal compress became a must -have every day. Essence

"I am not afraid of suffering or tired in space work positions, but just need a lot of opportunities to prove‘ I can ’. If you want to do‘ golden fingers ’, you need to prove that you can do better." Liu Tujie said.

Liu Tujie's family of three sent rockets.

Both Liu Tujie and her husband Li Fan are aerospace workers.

Ask the sky experimental cabin "Eyes" Hunan made

In addition to the "Golden Finger" from Shaoyang in Hunan, behind the success of the launching task of the Tiandi experimental compartment, there is also Hunan's scientific and technological power.

When the astronauts perform the off -cabin task, their visual scope and action amplitude will be greatly affected when they are under heavy cabin.

How to ensure the convenience and feasibility of the operation of the space officer's cabin? Changsha Xiangji Haidun Technology Co., Ltd. (hereinafter referred to as "Xiang Ji Shield") provided by the cabin can clearly display the image information obtained by the front -end micro camera of the operation tool in front of the astronauts, the function is similar to the "medical spare mirror" , To become the second pair of "eyes" of astronauts, ensuring the smooth implementation of the off -space tasks.

It is worth noting that due to the special space environment and no external power supply system, the off -cabin display has to face difficulties during the development process: the display screen and its own battery system need to withstand the impact of a significant high and low temperature outside the cabin. To this end, Xiangji Haidun has developed a display with advantages such as strong temperature adaptability and low power consumption. At the same time, it comes with a temperature control system with its own battery. Even in the face of the harsh environment outside the cabin The aerospace officer's outlet task is successfully completed.

This time, Xiangji Haidun also provided two small -size cabins in the experimental compartment to ask for display and state control with the instrument equipment. Although these small -sized screens are small, they are "all in the five internal organs." Display driver modules, touch control modules, etc. are hidden behind their "back". Such a "small and beautiful" is realized that scientific researchers have been realized after repeated consideration, reasonable design, precise layout, and gradual iteration.

Another smart display is the same as the intelligent display in the rail core compartment. It shoulders related tasks such as asking the test parameters, environmental parameters, ensuring parameters of the system, video monitoring of the cabin, and information monitoring of the aircraft.

data

The total length of the experimental compartment was 17.9 meters, 4.2 meters in diameter, and the launch weight was 23 tons. This head and weight are similar to a carriage of the Beijing Metro Line 13 train. It is the most important single -cabin active aircraft in the world in the world.

Qi Tian's experimental cabin is equipped with a pair of two -freedom flexible solar windsurfing. After all, the wingspan is more than 55 meters, which is longer than half a football field. It refreshes the record of the use of the solar windsurgery in my country on orbit.

Ask the experimental cabin, what to do with heaven

As the second cabin construction of my country's space station, I asked the Tianjin experimental cabin not only to have a large block, but also a "all -round" player integrating platform function and load function. So, what new equipment is brought to the space station? What experiments will be carried out in the future?

Ask the working cabin of the Tiantian Experimental Curring, there are 3 sleep areas and 1 sanitary area. After completing the docking, the space station can support the six astronauts of Shenzhou No. 14 and No. 15 to achieve the "Space Society" and rail rotation in the rails, and hand over in space. In addition, I asked the Tianjin experimental cabin and the core compartment of the sky and the core compartment. The key platform functions are consistent and can completely cover the work requirements of the space station combination.

It is reported that I asked the Tiangan experimental compartment mainly for the research science research of space life. In terms of test load functions, I asked the Tianyan experimental cabin to carry 8 experimental cabinets such as life ecology, biotechnology and gravity science. Moving a large scientific laboratory to space. The astronauts were working as a "bedroom" when they asked the Tianjin experimental cabin.

Lu Congmin, a researcher at the Space Application Center of the Chinese Academy of Sciences and deputy chief of the manned aerospace engineering space application system, said that of which, the life ecological experimental cabinet is based on multiple types of biological individuals (such as plant seeds, seedlings, plants, and small animals) as the experimental sample. The space growth experiments of Arabia, nematodes, fruit flies, zebrafish and other animals and plants, reveal the impact of micro -gravity on the growth, development, and metabolism of biological individuals, promote human understanding of the essence of life phenomena, study spatial radiation biology and sub -magnetism Biological effects and mechanisms, explore the establishment of an application -oriented life ecosystem, and provide scientific basis for astronauts to evaluate and protect the evaluation and protection of astronauts.
