The core cabin of 'Tianhe' rushed to the blue sky, carrying a lot of 'black technology'

At about 11:00 on April 29, 2021, with the expectation of hundreds of millions of Chinese people, the Long March 5B Yao-2 carrier rocket carrying the Tianhe core module of the space station was ignited and lifted off at the Wenchang Space Launch Site in my country. The capsule was successfully separated from the rocket and entered the predetermined orbit. After that, the two wings of the solar panel were successfully deployed and worked normally. The launch mission was a complete success. It is reported that China's space station is named as“Tiangong”. The entire space station adopts a horizontally symmetrical T-shaped configuration and will consist of a core module and two experimental modules. The Tianhe core cabin has a take-off mass of 22.5 tons, a total length of 16.6 meters, and a maximum diameter of 4.2 meters. It consists of a node cabin, a small column section, a large column section, a rear channel and a resource cabin. As the core module, Tianhe is the main control module of the space station, the management and control center, and the main place for astronauts to live. It is responsible for the power circuit, environmental control, and life support functions of the entire space station, including gas pressure, composition, temperature, humidity adjustment, water recycling management, microbial control and waste management, etc., which can meet the needs of astronauts for long-term space flight. Daily needs. In addition, the Tianhe core cabin has a large robotic arm, and the slender part in front of it is the node cabin. The tail of the Tianhe core module can be connected to a cargo spacecraft. During the construction of the space station, the docking port of the node cabin port of the Tianhe core cabin will first complete the docking with the experimental cabin; then the experimental cabin will be transferred to the left/left of the node cabin through the operation of the transposition base or the robotic arm. The two berthing ports on the right side enable long-term parking. Tianhe is worth looking forward to. The black technology of instrumentation is indispensable. It is understood that Tianhe has 4 core technologies, equipped with electric propulsion engines, followed by solar cells with high photoelectric conversion efficiency, and of course a degree of freedom machine. Arm, and finally equipped with 16 large scientific research combination cabinets. It can be said that the advent of Tianhe means that China has made new achievements in the construction of the space station. In addition to the above technologies, Tianhe also carries a measurement system camera device, which is installed in various parts of the rocket, mainly for monitoring. During the launch of the rocket, the engine compartment, booster separation, fairing separation, star-rocket separation and other working processes are provided, and real-time video images are provided to provide clear and accurate image monitoring for the rocket's launch process. The mobile photoelectric tracking and measurement equipment participated in the drift measurement and scene recording tasks during the launch process, providing important information and data for the space station sky and core module launch drift measurement and scene recording work. In addition, the dual-channel gas chromatograph is an important component of the space station's environmental control, health and maintenance system, and is used for online monitoring of trace volatile organic compounds in the cabin air. Its dual channels work independently, and can simultaneously analyze more than 50 organic components in one sampling. It can also be used in conjunction with a mass spectrometer. It is an indispensable product to ensure the safe survival of astronauts in orbit. The dual-channel gas chromatograph is small in size, light in weight and low in power consumption, and realizes the localization of key components. It will provide technical support and support for the environmental control and life-protection system of the Chinese space station, and provide support for the development of deep space exploration analysis and detection support equipment in my country. accumulated technology.
