A number of independent technologies escort Shenzhou
At 20:50 on June 5, 2022, Beijing time, three astronauts from Shenzhou 14 successfully entered the Tianhe core module.
In the future, the astronaut crew will carry out related work as planned.
As the deputy commander-in-chief of my country's manned spaceflight project, in this mission, the series of products independently developed and produced by China Aerospace Science and Industry Corporation escorted the flight mission of the Shenzhou 14 manned spacecraft.
The "Precision Surveyor" of the Rendezvous
The Shenzhou 14 manned spacecraft adopts an autonomous rapid rendezvous and docking mode, and successfully "hand in hand" with the Chinese space station.
The microwave radar developed by the 25th Institute of the Second Academy of Aerospace Science and Industry of China cooperates with the microwave transponder installed in the core cabin of the space station to escort the mission of space rendezvous and docking.
This is the ninth time for the rendezvous and docking microwave radar developed by China Aerospace Science and Industry Corporation to embark on a manned spaceflight project.
The radar undertakes the task of precise measurement of relative motion parameters such as distance, speed, and angle between medium and long-distance space vehicles, and is a key measurement sensor for space rendezvous and docking.
The high-precision accelerometer combination (hereinafter referred to as the "high-accelerometer combination") and several accelerometers developed by the 33rd Institute of the Third Academy of Aerospace Science and Technology of China have also made new contributions in the rendezvous and docking mission.
They have successfully completed the acceleration measurement task in the microgravity environment, helping the spacecraft to accurately grasp the speed and position, and making the rendezvous and docking stable and accurate.
As a product that has been with Shenzhou-1 and has been continuously upgraded, the accelerometer developed by China Aerospace Science and Industry Corporation has performed well in my country's previous manned aerospace engineering missions, and plays an important role as a "docking surveyor" in the microgravity environment of space. The character is a trusted and meritorious member of the spacecraft.
Beginning in 2008, according to mission requirements, the Gaojia combination entered the research and development stage.
In this combination, the accelerometer is no longer a "single soldier", but is functionally integrated with its "translator" IF conversion circuit, and the compatibility and stability of each device are optimized through system optimization.
Yu Huanan, the chief designer of the Gaojia combination, said: "If the accelerometer is like Yu Boya, who has superb piano skills, then the IF conversion circuit is its confidant Zhong Ziqi. The combination of the two ensures that one can measure accurately and the other can solve it. Accurate." Since then, the high-speed plus combination with this "ace CP" as the core device has shown its talents. For more than 10 years, the high-speed plus combination and similar products have successively helped Shenzhou series spacecraft and lunar exploration projects to succeed.
"Intimate waiters" for life in space
In space, astronauts can taste delicious Chinese flavors, enjoy space massage, and conduct real-time health monitoring.
These are inseparable from the "Space Kitchen", "Space Hospital" and "Space Air Conditioning" series of products independently designed and produced by China Aerospace Science and Industry Aerospace Sanjiang Hongfeng Company, which provide guarantee for the comfortable life of astronauts in space.
The five products, including food heating device, gas flow control valve, liquid circuit stop valve, physiological signal test box, and electrocardiogram recording device, which went on the expedition with Shenzhou No. 14, are mainly used in the Shenzhou spacecraft’s environmental control and health protection system and medical monitoring system. The medical insurance equipment subsystem, which is part of the "space kitchen", "space hospital" and "space air conditioner", creates a comfortable space home for astronauts.
It is understood that after the Shenzhou 13 manned spacecraft was launched into orbit, the three astronauts successfully entered the space station, used the "space kitchen" for many times to heat food, and used the "space massager" to relax the leg muscles.
The Chinese Astronaut Research and Training Center sent a congratulatory message to Hongfeng Company, fully affirming that the relevant products "work normally in orbit, their performance meets the mission requirements, and they are in good condition, which effectively guarantees the smooth development of the flight test mission of the manned space station."
In the "space kitchen", there is a food heating device with 3 layers of heating space, and astronauts can enjoy hot meals in space with only a short wait.
In addition, the physiological signal test box and ECG recording device worn on the outside of the thigh by the astronauts are products of the "Space Hospital", which accompany the astronauts to complete the entire flight mission, and can monitor the astronauts' ECG, breathing, The three physiological indicators of body temperature are transmitted to the ground command center for monitoring by the medical staff on the ground.
Skilled "escort"
The search and rescue information system developed by the 706 Institute of the Second Academy of Aerospace Science and Industry of China is a highly skilled "full-course escort". It undertakes the emergency search and rescue command of the waiting, ascending, operating and returning sections of the Shenzhou 14 manned spacecraft. Guarantee mission.
The system has the functions of search and rescue force management, search and rescue mission planning, search and rescue plan simulation and deduction, mission execution tracking and situation display, etc. It provides services for astronaut search and rescue mission pre-operation planning, in-process command and dispatch, and post-event review analysis. It is the space station mission to achieve aerospace It is a key system for personnel rescue and support, and plays an important role in the construction of manned spaceflight projects.
Another "escort" is to escort the flight communication, to ensure a clear sound surface filter throughout.
According to reports, once the spacecraft is launched in space, once there is signal interference, the content received on the ground is like answering a phone that is connected to the line, and it is difficult to distinguish accurate information.
In order to ensure clear communication throughout the flight, the SAW filter independently developed by 23 Institutes of the Second Academy of Aerospace Science and Industry of China can effectively filter out various interference signals of different flight stages and cosmic clutter in space, ensuring that the communication is transmitted back to the ground clearly and accurately. .
