Kukurais and multi -noodle "Tianzhou" more than courier

Bleak

After human society entered the era of commodity economy, the division of labor is increasingly detailed, and production and consumption gradually separate in time and space. Therefore, the middle link of connecting production and consumption -logistics was born. For China's manned space engineering, the heavy responsibility of logistics is on the spacecraft nicknamed "courier brothers" and "space courier" by netizens, that is, my country's "Tianzhou" series of freight ships.

From bicycles, private cars, buses, subways, and the seductive tricycles of Manchong, diversified transportation constitutes a three -dimensional urban transportation network. After the problem, gradually move towards professionalism and systematic. We not only have a manned round -trip system composed of the Long March 2 F Gold Rockets and the "Shenzhou" spacecraft, but also the cargo transportation system consisting of the Long March VII rocket and the "Tianzhou" spacecraft. The former is responsible for the safe transportation of the astronauts and sending it home, and the latter specializes in transportation propelled agents, space science experimental equipment and the living supplies of the astronauts.

Even if the renewable technology has made great progress, the astronauts on the space station have been able to enjoy the water coffee treated by urine smoothly, but the environmental control and life support system in the space station have not fully closed the loop, more Consumption also rely on freight ships to supply. Once the cargo spacecraft fails to launch or docking, the space station is facing the risk of "cutting". In this sense, freight ships are the lifeline of space stations. However, the "Tianzhou" series of freight ships can be more than that.

"Tianzhou" Skills 1: On Rail Science Experimental Platform

A number of scientific experiments and technical experiments can be carried out on the "Tianzhou" series of freight ships. Micro -intensive resources are precious and scientific experiments are standard tasks of navigable sky. From the unmanned spacecraft and the manned spacecraft to the space station, aerospace technology workers used each inch space in each spacecraft to the extreme. According to media reports, in the scientific experiments carried out on "Tianzhou -1", the "Key Technical Verification of Non -Newton's Gravity Experimental Test" project verified the performance of the high -precision static suspension acceleration meter in the orbit. "," Spatial Gravity wave Exploration "and other space plans provided important support;" Study on the Research on Cell Proliferation and Division of Cell Proliferation "projects are expected to be applied to the treatment of the heart and liver disease, organ transplantation, reproductive health, prevention and treatment of bone changes in bone quality changes Diseases, etc.

"Tianzhou" skill two:

my country's space station is designed in the orbit life for ten years, and the promotion agent supplement is a skill that must be mastered. The "Tianzhou" series of cargo spacecraft promotion agent supplementary tests, as a key verification project before the construction of the space station, laid an extremely important foundation for the construction and operation of my country's space station.

"Tianzhou" skill three: stable space station posture

We often see that the "Tianzhou" freight ship that has completed the shipping task of the goods still stops at the space station for a long time. One of its functions is to assist the stability of the space station. When a freight ship is connected with the space station, the interference force will be given to the node cabin during the docking impact, which will cause the core compartment to cause attitude disturbance, and the presence of the previous freight ship will greatly reduce the adverse effects of this interference.

"Tianzhou" Skills 4: Control some control of the space station

The "Tianzhou" series of freight ships play an important role in the normal operation of the space station. In addition, the freight ship blessed the "kung fu" of power supply and controlling the stance of space stations. There is a two -way parallel power supply capacity between "Tianzhou" and the space station, which means that in the case of insufficient electricity in the space station, the "Tianzhou" grid -connected controller can "nurture the mothership" and power the space station. In addition, in order to save the energy and pushing agent of the space station, under the necessary circumstances, the "Tianzhou" can also use its own promotional agent to adjust the space station's posture or even track.

The luck of our generation of aerospace enthusiasts is to witness the glorious results of Chinese manned space -on flight missions. The Chinese space station system consisting of the core compartment, the experimental cabin and the manned spacecraft and the cargo spacecraft will be completed in 2022. A few years later, it is likely to become the only space station that humans run in space.
