The Shenzhou 13 manned spacecraft carried a lot of supplies, carried the hope of the Chinese people, completed its mission and returned to Earth. This spacecraft carried three astronauts and operated in a fixed orbit for five months. It made many technological breakthroughs and created many new achievements. The editor below introduces the breakthrough of Shenzhou 13.
The return mode is fully automatic
Shenzhou 13 has made major innovations in return technology. On the one hand, it simplifies the return steps, and on the other hand, it adopts a fully automatic mode, which does not require astronauts at all. intervention. Return steps include braking out of orbit, free descent, atmospheric entry and landing. As a result, the return time is shortened a lot and the workload of the astronauts is reduced. Because the return speed of Shenzhou 13 was accelerated and the cabin of the spacecraft was shaking violently, the astronauts risked their lives to witness the new technology. As China's first female astronaut, Liu Yang flew on Shenzhou 13 and completed her mission.
The second extravehicular activity and space teaching and other milestones
The Shenzhou 13 manned spacecraft achieved a number of scientific and technological breakthroughs and attempted the first remotely controlled space station and cargo spacecraft. The docking set a new record for the length of continuous orbital flight by an astronaut, laying the foundation for the future development of China's aviation industry. The manned spacecraft conducted a series of tests and carried a lot of data and historical experience. When it returned, all data began to be tested automatically.
The quality of Bowei alloy new materials has been improved
Bowei Aerospace Materials has built the Shenzhou series of spacecraft No. 6, No. 7 and No. 13, keeping pace with the times. The material of the Shenzhou 13 spacecraft has better resistance to heat and cold pressure, is easier to weld and process, and its strength has been increased to more than 800MPa, achieving good antimagnetic and wear resistance, maintaining good elasticity and stability, and withstanding the special temperatures in space environmental pressure. The Shenzhou-13 spacecraft exists in extremely low-temperature and high-temperature environments. On the one hand, it must adapt to the environment, on the other hand, it must maintain good communications and complete a series of tasks. Bowei Alloy Materials develops and progresses together with China's aerospace industry.
