China Aerospace Science and Technology successfully escorted the launching task

Author:Global Times Time:2022.07.24

On July 24, 2022, the Long March 5 Yao Three Launar Rockets were equipped with the first scientific experimental cabin of China Space Station -Qi Tian's experimental cabin, which successfully took off at the Wenchang Aerospace launcher, marked another important step in the construction of my country's space station. The series of products independently developed by China Aerospace Science and Technology Group Co., Ltd. provided important guarantees for the successful success of the launch of the test compartment.

After the launch of the experimental compartment was launched, the matching docking of the microwave radar developed by the 25th Hospital of China Aerospace Science and Technology Second Hospital was successfully helped to ask the Tiangan experimental compartment with the heaven and core compartment to achieve the connection.

This is the tenth time for the microwave radar series products to collect the Chinese manned aerospace project task, which undertakes the precise measurement task of the relative motion parameters such as the distance, speed, and angle of the medium and long distance space flight. Instrument.

Since 1999, the microwave radar team has devoted himself to studying space meetings and measurement techniques. It first debuted in the docking mission of Tiangong -1 and Shenzhou 8 and successfully completed the task. For more than two decades, the microwave radar has handed over the perfect answer sheet of "ten wins and ten wins" in my country's manned aerospace mission.

Also repeatedly set up new achievements in the matchmaking task, the high -precision acceleration meter combination developed by the 33 House of China Aerospace Science and Industry III -Quartcar Exception Meter and I/F (current/frequency) conversion circuit. This pair of "golden partners" provides the most reliable measurement data for the real -time "perception" of the experimental cabin to ensure that the connection is smooth and smooth.

The reason why the acceleration meter can accurately complete the measurement task is inseparable from its precise processing. The quartz film inside the acceleration meter needs to be specially "carved". The thinnest "beam" is about one -third of the thickness of the hair wire. The loss of the film. To this end, 33 built an advanced cleaning room and processed and assembled at constant temperature. After precision assembly, the acceleration meter must also be tested like "purgatory", including cycling temperature tests, high -level shock tests, and aging tests of the combination of vibration and temperature. Only qualified to "exist" space.

"Space Water Purifier" supports long -term residence

In this launch mission, the second set of environmental control of the urine treatment subsystem developed by the 206 of the Second Hospital of China Aerospace Science and Technology House was lifted with the Tiangtian Experimental Crystal.

As an iconic key product that takes the long -term residence of astronauts, the urine treatment subsystem is an important part of the space station environmental control birth insurance division system. It is an important part of the cycle of water resources in the space station. "".

It is reported that after the first urinary treatment subsystem was launched in April 2021, the system performance was stable and running normally. The second set of urine treatment subsystems followed the interview compartment, marking that there will be two sets of "super water purifiers" in China space station to ensure space water. In the subsequent long -term operation phase, the urinary treatment subsystem in the cabin is the main part. It runs normally according to the working rhythm. Ask the Tianjin experimental cockpit urinary treatment subsystem as a backup, and jointly provide important guarantee for the long -term space staff to stay in space.

"Small products" play "big energy"

The construction and operation of the test cabin is an extremely complex system engineering. It is large and technical, consisting of tens of millions of high -tech products, and even a screw is crucial.

The magnetic device developed by 23 Chinese Aerospace Science and Technology House of Secondary Hospital is only the size of a pens and caps. It is a core device in the power circuit of the experimental compartment power supply. Power equipment runs stably and reliably. A series of high -quality crystal components developed by the 203 of China Aerospace Science and Technology II Hospital, like the pulse of electronic devices, provides a stable time frequency benchmark for the system, and generates accurate and stable frequency signals.

The 111 Factory of China Aerospace Science and Technology Hospital has developed a small mooring agency to be moved by the experimental compartment. It is installed on the outside of the cabin and plays a role of a "socket". The passive terminal provides remote positioning through the target to active end, and the effective connection of the plate extension platform and the cabin through the connection between mechanical and power interfaces can provide energy support for other aircraft.

The gas flow regulating valve produced by China Aerospace Science and Technology Aerospace Sanjiang Hongfeng is one of the core components of "space air conditioning". The temperature and humidity of the air in the cabin can be adjusted by controlling the proportion of cooling and heat air flow. China Aerospace Science and Technology Henan Aerospace 695 Factory has developed a variety of circulating pumps and air filters in the air circulation system of an experimental compartment environmental control system, which can effectively ensure the air circulation and purification of the cabin and provide a comfortable cabin in the cabin staff. surroundings.

In addition, in this launch mission, the Aerospace Jiangnan, which belongs to China Aerospace Science and Technology, provided thousands of electric connectors, precision gears, special motors and other products for the test compartment. Tens of thousands of high -performance fasteners in China Aerospace Science and Technology Aerospace are connected to various institutions, shaping the "good body" of the test compartment.

Series of product escort rockets fly smoothly

In the process of launching the flight of the Long March 5 Yao Three Lauret Rockets, the two fixed pulse measurement radars developed by 23 Chinese Aerospace Science and Technology House of Science and Technology Second Hospital escorted the radar. Precision coordinate information such as pitch and radial speed. At the same time, the sound table filters developed by 23 are used to filter various interference signals such as high -dimensional harmonic, mirror information, launch leak signals, and various parasitic miscellaneous interference. The hydrogen turbine pump developed by the 111 Factory of China Aerospace Science and Technology Third Hospital is installed on the servo mechanism of the first -class engine of the carrier rocket, which is mainly used to adjust the rocket flight attitude. If the servo mechanism is the "steering wheel" of the carrier rocket, the hydrogen turbine pump is the "directional controller" of the steering wheel, which plays an important role in the smooth flight of the carrier rocket. The high -performance nano -gas gel insulation felt developed by the Third Hospital of China Aerospace Science and Technology has effectively isolated the high temperature of the rocket with its thin figure, stable and reliable thermal insulation performance, and protects the normal operation of electronic devices around the gas pipe road.

China Aerospace Science and Technology Aerospace Jiangnan provides thousands of connections, relays and other products for the carrier rocket, helping the Rockets to complete the flying angel. China Aerospace Science and Technology Henan Aerospace 695 Factory has developed key components such as high -voltage self -lock valves and small traffic self -lock valves for the carrier rocket position control system.
