What do you know about Shenzhou 5?

The Shenzhou series of manned spacecraft has completed a total of 7 manned missions from Shenzhou-5 to Shenzhou-15. The astronauts on these missions come from the Chinese People's Liberation Army Air Force and China's National Aircraft Sedans Virtual Sky Bureau. Shenzhou-5 was launched on October 15, 2003, carrying China's first female astronaut, Yang Liwei.

The mission had three people on board, the other two astronauts were Nie Haisheng and Jing Haipeng. Jing Haipeng later became the second Chinese astronaut to complete a walking mission in space.

In the Shenzhou-7 mission, the astronauts are Nie Haisheng, chief scientist of the Chang'e-1 lunar exploration mission, and Air Force Major Generals Jing Haipeng and Chen Quanguo. Nie Haisheng and Jing Haipeng completed the 15-meter-long skywalk mission outside the space station for the first time, breaking the international record for astronauts' space walk. The Shenzhou-9 mission has three passengers, namely commander Zhan Linlin, astronauts Xu Jingchun and Wang Yaping.

The Shenzhou-11 sent astronauts Jing Haipeng and Chen Dong to Tiangong-2, where they stayed for 33 days, setting a record for the longest space stay in the history of China's aerospace industry.

Shenzhou-12 carried three astronauts, Ding Junhui, Chen Dongsheng and Wang Yong. Wang Yong is the first astronaut to represent the Chinese team in the International Space Competition and win the "Best Space Walk Award". The astronauts on Shenzhou 13 and Shenzhou 10 Fan Fan 4 are Jing Haipeng and Chen Dong, who have further refined the pairing technology and other scientific experiments on the basis of Shenzhou 9.

In the continuous development and progress of China's aerospace technology, the Shenzhou manned spacecraft has carried batch after batch of outstanding astronauts and completed one great feat after another in China's aerospace history. These astronauts not only carry the country's expectations and glory, but also demonstrate the spirit and talent strength of China's aerospace industry. <>

Qi Fayun. In 1957, he graduated from the former Beijing Institute of Aeronautics and Astronautics (now Beijing University of Aeronautics and Astronautics) and was assigned to work at the China Academy of Launch Vehicle Technology. In 1976, he was transferred to the China Academy of Space Technology to engage in the development of satellites and spacecraft, and served as the vice president and president of the institute, and served as the chief designer of several satellite models and spacecraft.

He is currently the technical advisor of the China Academy of Space Technology, the dean and honorary dean of the School of Astronautics of Beijing University of Aeronautics and Astronautics, a doctoral supervisor, and the vice chairman of the China Committee of the International Committee on Space Research. Academician of the International Academy of Astronautics, No.

Analysis: Introduction to Shenzhou 5.

The Shenzhou-5 spacecraft successfully achieved China's first manned space flight, fully demonstrating that a number of key technologies on China's spacecraft and rockets are now in the leading position in the world.

In order to enable astronauts to have a comfortable and safe environment in the return capsule, the developers finally selected a low-density ablative heat-proof material after many experiments, so that the outside of the spacecraft can still be kept at about 20 degrees above minus 20 degrees even when it is minus 100 degrees to minus 3000 degrees. ”

There are many more original technologies like this in the development of the Shenzhou spacecraft. As China's first generation of manned spacecraft, Shenzhou 5 has surpassed the design of single cabin and double cabin, and directly adopted a multi-functional spacecraft scheme composed of three cabins. Although Shenzhou 5 only carried one astronaut this time, we designed it to carry three people at the same time.

Qi Fayun, chief designer of the Shenzhou spacecraft: (Shenzhou) The spacecraft started relatively late, but our starting point is relatively high, and we have done it in one step. Where is it, we have adopted 3 cabins at once, and added an additional section such a layout, so that our ship can be transported back and forth between heaven and earth at once.

After the astronauts return to the ground, the orbital module of the Shenzhou-5 spacecraft will work autonomously in space like a satellite under unattended conditions, which greatly extends the working life of the spacecraft in carrying out space applications and scientific experiments.

The return capsule of the Shenzhou 5 spacecraft is meters high, equivalent to a six-square-meter room, and is currently the largest spacecraft return capsule in the world. In order to ensure the safe return of the three-ton return capsule to the ground, the research and development personnel also specially designed the world's largest return landing parachute with an area of 1,200 square meters when the spacecraft landed and decelerated, so that the landing speed of the return capsule was reduced by more than 20 times in more than 10 minutes.

President of the Chinese Academy of Sciences ** explained that China's aerospace industry is no longer at the ordinary level, has entered the world's advanced ranks, its reliability, its carrying capacity, its control system, its safety guarantee system and so on have reached the top three positions in the world.
