"Ask the sky" 叩 叩 ““ ““ ““ ““ “

Yin Jiangyong, a reporter from Henan Daily Client

On July 24th, with the successful launch of the Long March 5 Yao Three Lauret Rockets, the China Space Station ushered in a new cabin -asked the Tiantian experimental cabin. This is the connection between the two spacecraft with the largest tonnage in my country, and it is also the first time that my country's space station has met and docking in a state. Many high -tech equipment from Henan have escorted this "asking the sky" journey and made new achievements.

27th Institute of China Electricity Department

"Laser Eye" in space "piercing needle lead"

China Space Station is a spatial laboratory system assembled in the orbit, including five modules: core compartment, experimental cabin, experimental compartment Ⅱ, manned spacecraft, and freight ships. The laser radar system developed by China Electronics Technology Group Corporation's 27th Institute is installed in 5 modules, forming an important role in space stations with various forms of space combinations and subsequent operations.

"The laser radar system we developed solves the problems of large dynamics, high -precision, and multi -parameter measured real -time measurement. In the second step of the three -step strategy of manned space engineering, it has successfully completed with the manned spacecraft and freight ships many times. In the docking task of the Rail Communications Fair, the advanced nature and reliability of the product is verified. "The person in charge of the institute proudly said that in the process of building a large -scale space station in the third step of the three -step strategy, the laser radar system will continue to exert the" needle piercing lead leader leader leader leader "Important role.

Zhengzhou Aerospace Electronic Technology Co., Ltd.

"Neuro.com" builds information transmission "highways"

The electrical connectors, cable networks and other component products around the body of the experimental compartment are built, and the "highway" of information transmission in the body is constructed. In this launch task, Zhengzhou Aerospace Electronics Technology Co., Ltd. developed and produced more than 10 series and nearly two -thirds of supporting electric connector products in the experimental compartment, and shouldered the important mission to ensure the precise transmission of various signals. One of the "Star Products" -the power connectors outside the cabin is still a key component that guarantees the successful "holding hands" of the test compartment and the core compartment of the sky and the core cabin.

The connector used by the spacecraft should adapt to a series of severe tests such as electromagnetic interference, thermal circulation, thermal vacuum, and radiation with charged particles in the high vacuum environment of the space orbital to meet the requirements of the long life of the space station. "It can be said that the electrical connector connected to each part of the component of the spacecraft, each plug, each wire, and each solder point is related to the accuracy of the signal and circuit transmission. Therefore Be glorious to be refined and lost, "said the person in charge of the company.

Henan Aerospace Hydraulic Pneumatic Technology Co., Ltd.

Guarantee rocket launch "steady" and cabin air "net"

Ask the Tianjie experimental cabin is the main life and working cabin section of the astronauts. It can support the living security of 6 astronauts during the period of the two -manned spacecraft rotation with the Tianhe Core Card, and provide a special air gate. Activities to carry out large -scale sealing cabins and exterior space science experiments and technical experiments.

In this launching task, Henan Aerospace Hydraulic Pneumatic Technology Co., Ltd., in order to ask key parts such as the high -voltage self -lock valve developed by the supporting posture control system of the Tiangong experimental compartment, can be regarded as a switch that controls the "sports nerves" of the carrier rocket. Instructions to achieve precise control, which mainly guarantee the entire system has good stability and operability in the flight process, and ensure that the experimental compartment is accurate. In order to ask a variety of air filters for the development of the experimental cabin, it can effectively ensure the circulation and purification of the air inside the room, and provide a strong guarantee for the safety research tasks of spacemen to carry out space scientific research tasks.

22nd Research Institute of China Electricity Department

"Hui Eye" is "Ask the Heaven" throughout the process

In this task, a pair of radio wave technology and observation application "Hui Eye" refined by the 22nd Research Institute of China Electronics Technology Group Corporation, to escort the normal operation of the aerospace measurement control and target tracking system for the "Ask Heaven" mission.

"The rails of the spacecraft are highly scattered with a large number of aircraft and space fragments. The precise rail measurement is the prerequisite for ensuring flight safety." The relevant person in charge of the Institute said that the institute has the only domestic electric wave environment observation station network. It is currently 24 hours. Continuous monitoring of the environmental status of space waves, and ensuring the reliable operation of systems such as aerospace measurement, satellite communication, and spatial target monitoring radar.
