The first launch of the Chinese space station in 2022 was a complete success. What is the mission of Tianzhou-4? There are 5 highlights
The recent successful launch of China’s Tianzhou-4 spacecraft has brought a large number of materials to the space station that the astronauts will need to use next. It also marks the official start of the construction of the Chinese space station in 2022. What is the significance of this launch? For ordinary people, this launch will reveal five major highlights. The first launch of the Chinese space station launch mission in 2022 will finally be a complete success. What is the mission of the Tianzhou-4 that was launched this time? For ordinary people, there are five major points of interest in this launch.
Let’s talk about the first point of view. This is the large amount of goods that Tianzhou-4 will bring to the Chinese space station. For Takionauts, these goods are comparable to a real gift package. Tianzhou-4 is loaded with Takionauts. Systems, space station systems and space applications, as well as cargo spacecraft systems totalling more than 200 sets of cargo, including packaged packages and direct-installed cargo, as well as 750 kg of additional propellant for the space station, the reason for the increase in propulsion The reason is that the space station needs to use propellant frequently to adjust its attitude while maintaining its orbital altitude during operation, otherwise it will continue to lose orbital altitude. In addition to the loading of goods, Chinese aerospace engineers have also made a series of unique innovations. By adding labels and colored handles, astronauts can easily find the required packages on orbit. Greatly improve the efficiency of cargo transportation and use.
The Tianzhou-4 spacecraft itself is the second point of interest. It is a cargo spacecraft with the largest active transportation capacity and the most comprehensive on-orbit support capability in China. Therefore, the spacecraft was successfully launched and provided material support for the Shenzhou-14 crew. Space station operation support and scientific experiments, this series of actions can effectively verify China’s technical level in the design and manufacture of cargo spacecraft. The third point to watch is the docking of the Tianzhou 4 spacecraft and the Chinese space station. Although the docking of the spacecraft seems to be very light from the TV broadcast, in fact, every spacecraft flying in space orbits is in the Exceeding the first cosmic speed, which is 7.9 kilometers per second, and its weight is often more than 10 tons or even 10 tons, the energy contained in it is very huge. How to accurately control the two spacecraft to achieve precise alignment and safe connection? It is quite a test of the docking mechanism of the cargo spacecraft. In order to achieve this effect, Chinese designers have successfully used the idea of controllable damping through a large number of technical research and program demonstrations to realize the safe docking of the spacecraft through buffer facilities.
The fourth point to watch is the carrier rocket that carries the Tianzhou-4 spacecraft. This time, the Chang Zheng -Long March-7 Carrier Rocket will be responsible for the launch of the Tianzhou-4 spacecraft, and China has accumulated a lot of experience in the use of the Chang Zheng -Long March-7 Carrier Rocket , so in order to further compress the time spent on the entire launch and docking process, Chinese engineers optimized the rocket, the launch process, reduced the test and launch cycle, and shortened the original 31-day cycle to 27 days, which is also the domestic Long March For the first time on the 7th, the launch preparations were completed within one month. The last point to watch is that within one year of this year, China will complete the on-orbit construction of the Chinese space station through the Tianzhou-4 and Tianzhou-5 spacecraft. After completion, the entire space station will present a T-shaped structure, which is enough for three Takionauts to live and work in it. At the same time, a series of scientific facilities installed in it will also allow China to conduct a series of space science experiments, thereby improving its own technology. level.

中国航天科技集团 China Aerospace Science and Technology Corporation Bai Mingsheng, chief designer of the cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group on the 15th May 2022, revealed in the CCTV “Face to Face” interview: Tianzhou No. 3, No. 4 and No. 5 were produced in one batch, and we will set aside time for the follow-up, from No. 6 to No. 11. No. 6 is another batch and will do system upgrades. In fact, the design work for No. 6 has been completed and the final assembly has begun.
The cargo compartment will be greatly improved, and the cargo transportation capacity of the airtight compartment will be greatly improved. In the future, the time to provide support for astronauts will be further extended. Now, two ships a year, and three ships in two years may be enough in the future. This will greatly improve the economic efficiency.
Bai Mingsheng also revealed that there will be a large number of products and experimental results that need to be returned in the future, and we will design a return-type cargo spaceship. Because to have the ability to return, it sacrifices the ability to rise. At present, the results of the initial experiments of our space station are not that many. There are a small number of descendants by manned spacecraft, but their capabilities are limited. When such a capability is really needed in the future, a returnable cargo spacecraft can be designed. At present, the plan of de-orbit destruction of cargo spacecraft is the most economical plan. In the future, according to changes in demand, we will have a return type and a non-return type, and different types will be developed in the future.
Tianzhou No. 6 begins final assembly! The carrying capacity of the new batch of cargo ships has been greatly improved] Tianzhou No. 3, No. 4 and No. 5 were produced in one batch, and Tianzhou No. 6 to No. 11 were produced in another batch. Bai Mingsheng, chief designer of the cargo spacecraft system of the Fifth Academy of China Academy, said: At present, the design work of Tianzhou 6 has been completed and the final assembly has begun. The cargo compartment of Tianzhou-6 will be greatly improved, and the cargo transportation capacity of the sealed compartment will be greatly improved. This means that the time to provide support to Takionauts will be further extended in the future. Now, two rounds per year may be enough in the future, and the economic benefits will be greatly improved…..
