Original title: Shenzhou XIII successfully fly to the sky!Aerospace Science and Industry “Quasi Stable Health” Escorts Astronauts’ Space Trip
At 0:23 on October 16, the Long March 2F remote launch vehicle carrying the Shenzhou 13 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center. About seconds later, the Shenzhou 13 manned spacecraft was successfully separated from the rocket. Entering the scheduled orbit, the three astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu were successfully sent into space. The flight crew was in good condition and the launch was a complete success. Yuan Jie, deputy commander-in-chief of China’s manned space engineering, secretary of the Party Group of Space Science and Industry, and chairman of the board of directors, Yuan Jie attended the space expedition ceremony of the Shenzhou 13 astronaut flight crew at the Jiuquan Satellite Launch Center and sent off three astronauts to space expedition.
As the deputy commander-in-chief of the manned spaceflight project, China Aerospace Science and Industry Group Co., Ltd. has undertaken the development and production tasks of multiple stand-alone products, a large number of industrial basic parts, and electronic component products to create a “quasi-stable” for the Shenzhou 13 astronauts. Kang’s space journey.
In this mission, multiple systems including the launch site, launch vehicle, Shenzhou spacecraft, landing site, etc. all contain core technologies and products of Aerospace Science and Industry: The systems developed by the Aerospace Measurement and Control Company have good compatibility, high precision, high speed and reliability. A series of high-performance measurement and control equipment can carry out a full range of automated inspection and control for the launch vehicle, and provide a full range of “physical examination” services; the metal hose developed by Aerospace Chenguang continues to operate under extreme environments with complex loads and wide temperature ranges. The engine fuel is smoothly fed into the combustion chamber to provide sufficient power for the rocket; the sound meter filters and chokes developed by the 23 Microelectronics Corporation of the Second Academy continue to provide communication support services for key parts of the spacecraft; a series of research developed by the 203 Academy of the Second Academy The high-quality crystal component products provide a stable time and frequency reference for the entire flight mission to ensure that the space flight mission can be “visible” and “heard clearly”; The gear transmission products with excellent performance in the “12” provide reliable transmission guarantee for the docking mechanism of the aircraft; the power distribution products on the launch vehicle developed by Aerospace Jiangnan Aerospace Electric are responsible for power transmission, command information transmission and other tasks, which can be called rockets” “Bloodline” channel; Meiling zinc-silver battery, which is well-known in the aerospace field, provides continuous power for launch vehicles and manned spacecraft; the connection and separation mechanism product developed by the 111 factory of the Third Academy is between the orbital module and the return module, the return module and propulsion The executor of the key actions between the cabins, the heat-proof outsole of the return cabin and the cabin body; dozens of sets of key special valves developed by Henan Aerospace 695 Factory are responsible for controlling the medium flow, on and off of the thermal control sub-system, and maintaining the cleanness of the system medium. It can be called a key “housekeeper” for the protection of the rocket thermal control system; tens of thousands of high-performance fasteners of Aerospace Seiko connect the various mechanisms, relying on reliable quality to fasten the various components together, and shape the ” “Shenzhou 13” has a good body.
“Quasi”: Casting the “Eyes of Space” with precise docking
The microwave radar developed by the 25th Institute of the Second Academy of Aerospace Science and Technology of China is used as a key measurement sensor to output high-precision ranging, speed and angle measurement information during the rendezvous and docking process, providing strong support for the rendezvous and docking mission in the construction of the space station.
In this rendezvous and docking mission, it was the “first show” of radial docking-the Shenzhou 13 spacecraft flew from the back to below the Tianhe core module, and docked with the Tianhe core module in the vertical direction. Compared with other pairs of interfaces, the complex scene of radial docking puts forward higher requirements on microwave radar, and further verifies the maturity and stability of microwave radar.
The microwave radar developed by China Aerospace Science and Industry has achieved platform-based and serialized development in technology, and is fully adapted to the normalized and rapid development trend of subsequent space station construction rendezvous and docking. Since participating in the space rendezvous and docking mission for the first time in 2011, it has successively guided the Tianzhou 2 and Shenzhou 12 spacecraft to complete the rendezvous and docking with the core module of Tianhe. The microwave radar has been the outstanding performance of the victory for the construction of the space station. And operation provides strong technical support.

The high-precision accelerometer combination (referred to as the high-plus combination) of the 33 Institute of China Aerospace Science and Industry Corporation still gives people “stable conviction.”
When performing tasks, the core component of the combination, the quartz flexible accelerometer and the IF conversion circuit, work closely together to accurately measure the acceleration in the microgravity environment, thereby helping the spacecraft to accurately grasp the speed, position and other information. Since the two core components perform different tasks separately, why must they be “combined” together? There are two main reasons. One is that the measurement accuracy of the accelerometer is closely related to the temperature change of the working environment, and it is extremely susceptible to the influence of the environment temperature. After being combined with the IF circuit, the technician can cleverly use the combined “package” to stabilize the working temperature. To control the appropriate point. The second is to use system thinking, through careful adjustments, to find the optimal matching parameters of the combination of the two, so that each device in it “thinks in one place, and works hard in one place” to achieve “1+1>2” Effect.
Starting from the mission of the Shenzhou XII spacecraft, the designers upgraded the IF conversion circuit according to the needs of the mission. It was upgraded from a simple output pulse to a counting pulse number, which provided convenience for improving the working efficiency of the system. In this process, the technical staff gave full play to the advantages of the system, continuously optimized the product design, coordinated and grasped the overall performance, and achieved the set goals steadily and reliably.
“Kang”: Create a comfortable space home for astronauts
In space, astronauts can eat delicious Chinese flavors, enjoy space massages, and real-time health monitoring… During this mission, the “Space Kitchen” and “Space Hospital” provide astronauts with a full range of care and build for astronauts. Comfortable space life.
Five products including the food heating device, gas flow regulating valve, liquid circuit stop valve, physiological signal test box, and ECG recording device that accompanied the Shenzhou XIII expedition were mainly used in the Shenzhou spacecraft environmental control life insurance sub-system and medical supervision and medical insurance. The equipment subsystems, which are part of the “space kitchen”, “space air conditioner”, and “space hospital”, create a comfortable space home for astronauts. These five products have participated in Shenzhou flight verification and use many times, and the technical status is mature.
The food heating device in the “space kitchen” has three layers of heating space inside. By gently pressing the power switch, the astronauts only need to wait a little while patiently to enjoy warm meals in space.

They are carried by the astronauts and are only the size of a cigarette case. They can monitor the astronauts’ ECG, breathing, Three physiological indicators of body temperature are transmitted to the ground command center for diagnosis by ground medical staff.
