China News Service, Xi'an, June 5th (Reporter Zhang Yichen) At about 10:44 on June 5, 2022, the Long March 2F Yao 14 carrier rocket carried three astronauts, Chen Dong, Liu Yang, and Cai Xuzhe. The Shenzhou 14 manned spacecraft set off again.

This is the first batch of Chinese astronauts to enter the "Tiangong" after the manned spaceflight project enters the construction stage of the space station in 2022.

On June 5, the Shenzhou 14 manned spacecraft was launched from the Jiuquan Satellite Launch Center in China.

  The Sixth Institute of China Aerospace Science and Technology Corporation (hereinafter referred to as the Sixth Institute of Aerospace Science and Technology) is responsible for various main thrust and attitude and orbit control engines on the Long March 2F carrier rocket and the Shenzhou 14 spacecraft in this manned spaceflight project. , thermal control subsystem and life support system pump valve and other research tasks, and supporting the return cabin, propulsion cabin two sets of propulsion subsystems and 9 kinds of 22 pump valve products.

  26 days ago, the Tianzhou-4 cargo spacecraft was successfully launched, and supplies were delivered in advance for this Shenzhou-14 manned spacecraft mission. The Tiangong Space Station is ready and waiting for the "space travel" trio for a period of time. half year stay.

  The Sixth Academy of Aerospace Science and Technology stated that for a rocket, the engine is one of the most important components. Therefore, in the launch mission and the subsequent series of scientific research experiments to be carried out by the astronauts, the rocket engine with high quality, high stability and high safety is required. And the development of space propulsion system has become the top priority.

  According to reports, the Long March-2F carrier rocket has a record of 16 successful launches and 16 successful launches, and enjoys the reputation of "magic arrow". However, in order to ensure the complete success of each manned space mission, the engine development team of the Sixth Academy of Aerospace Science and Technology A series of measures such as innovation in test technology and innovation in management methods have been adopted to create a more solid test system to ensure the successful completion of this manned spacecraft launch mission.

  Talking about the new technologies and processes in the production and assembly of the engine, Cheng Xiaohui, deputy director of the 11 Research Institutes of the Sixth Academy of Aerospace Science and Technology, told a reporter from that if some castings are produced according to the traditional process, it will take a long time. The use of 3D printing technology has the advantages of high efficiency and low cost.

  To develop aerospace, power comes first.

From the launch of China's first Shenzhou spacecraft in 1999, to the completion of China's first manned flight by the Shenzhou-5 spacecraft in 2003, to the "Shen 14" that undertook the first manned flight mission during the construction phase of China's space station, liquid power is in the process. role is crucial.

  The Sixth Academy of Aerospace Science and Technology stated that in 2022, the Shenzhou 14 manned spacecraft will complete a number of on-orbit tests, assembly and verification work. After the Shenzhou 14 crew enters the space station, the Tiangong space station will usher in many important attitude adjustments. and hull combination changes.

With the success of this launch mission, the Wentian and Mengtian experimental capsules will be launched in succession.

This move means that the size and capacity of the Chinese space station will be further expanded, and will be able to accommodate more astronauts and test equipment.
