China News Service, Beijing, November 8th (Mar Shuaisha Zhang Yushi Xiaodan) On November 8, astronauts Zhai Zhigang and Wang Yaping carried out the first outing of the Shenzhou 13 astronaut crew and successfully completed the installation of the robotic arm cascade device .
Behind every movement of the astronauts is the effort of the spacecraft engineer team of the Fifth Academy of China Aerospace Science and Technology Corporation to conduct hundreds of simulation exercises on the ground.
"Spaceship Test Driver"
Since the development of the Shenzhou manned spacecraft model, the special identity of the spacecraft engineer has been born.
The spacecraft engineer is not a separate post, and is often concurrently performed by the overall system, electrical, and mechanical designers of the Shenzhou team of the Fifth Academy of Aerospace Science and Technology Group.
From the design and production of the Shenzhou manned spacecraft, to launch and return, the spacecraft engineer team has always been the spacecraft's closest companion.
The various complicated operating platforms and operating interfaces in the spacecraft cannot be studied by the astronauts alone or by referring to paper tutorials.
The spacecraft engineers use themselves as substitutes for the astronauts and perform various tests on behalf of the astronauts during the ground test of the model to check whether the instrument display, manual operation, fault handling and other aspects meet the requirements.
"As a designer and improver of aerospace products, we must know every detail, and know every part of the spacecraft and every manual control command in the test." The Shenzhou manned spacecraft of the 5th Academy of Aerospace Science and Technology Group Said Gao Xu, deputy chief designer of the system.
Testing is a routine work for spacecraft models, but for spacecraft engineers, it is often necessary to change roles when entering the cabin and use themselves as astronauts to operate the spacecraft.
Ming Zhangpeng, the chief designer of the Shenzhou manned spacecraft system of the Fifth Academy of Aerospace Science and Technology Group, likened this process to a test drive to help astronauts understand and familiarize themselves with the "temper nature" of the spacecraft and ensure that each "boat of life" goes back and forth safely.
"In order to meet the design requirements of ergonomics and enable astronauts to carry out their work better, we need to change from the role of the designer to the role of the user, discover the problems of the spacecraft products, and provide feedback to the design team to achieve product design. Further optimization.” Ming Zhangpeng said.
"This young man can fight things"
Shenzhou 12 returned safely, Shenzhou 13 was successfully launched, and Shenzhou 14 was on standby. As the "rolling launch" mode was gradually established, the pressure on spacecraft engineers increased exponentially, but they were always optimistic about each mission. challenge.
"Post-90s" Xiao Xuedi, who just entered the General Design Department of the Fifth Academy of Aerospace Science and Technology Group in 2020, quickly assumed the responsibility of spacecraft engineer.
The manned spacecraft is complicated to operate. Each mission is often a combination of hundreds of manual commands and more than a hundred operation actions, and the command issuance requirements are extremely demanding. The minimum command interval is 5 seconds, and each command must be every second. There is no room for hesitation and carelessness.
Faced with harsh operations that ordinary people can’t handle, Xiao Xuedi, who is already an "veteran" after a year of experience, is full of confidence. There are densely packed labels to ensure that the issuing and operations after entering the cabin are foolproof."
"This glorious part-time job is accompanied by a mountain of heavy responsibilities. This young man can resist things." Yang Haifeng, the person in charge of manned spacecraft flight control, was a little moved when he mentioned these young spacecraft engineers.
In his view, those who can devote themselves to major manned space projects and personally improve these spacecraft that accompany astronauts to the sky are very rare.
This is a work of historical significance, and it is their supreme honor as a spacecraft engineer.
A total of more than a thousand cabins have been entered in the past ten years
From 2011 to the present, for ten years, the spacecraft engineer team has guaranteed the launch missions of six models from Shenzhou 8 to Shenzhou 13 with zero errors, accumulating more than a thousand invehicles.
"Since the start of manned spaceflight, in the face of a large number of technological gaps, the manned spaceflight development team has not shrunk, but has faced difficulties, with independent breakthrough technology as the goal, step by step, independent breakthroughs and mastery of manned spaceflight. The core key technology of China." Zhang Bonan, deputy chief designer of China's manned space engineering, looked back on the prosperous years, confident and confident.
Gao Xu, who graduated with a Ph.D. in 2011, has been rooted in the overall model position of the Fifth Academy of the Aerospace Science and Technology Group since the Shenzhou 9 spacecraft, and also served as a spacecraft engineer.
In everyone's eyes, he is desperate for work, "Saburo desperately".
The spacecraft engineer Ren Changwei used to enter the cabin for more than ten hours in order to coordinate with the test progress.
During that time, in addition to being exposed to electronic radiation, he also had to face the discomfort caused by the noise in the cabin and the heating of the equipment.
Through all the models of Shenzhou spacecraft, Chen Tongxiang, who is currently in charge of Shenzhou manned spacecraft product assurance, is very pleased to see the growth of young people, but also feels distressed for these technical backbones who have grown up through experience.
She said, "These young people have a sincere heart and a sincere love. For the work at hand, they can desperately, sleep and rest, just for success." (End)
