Decrypting Shenzhou No. 14 丨 Three -cabin structure Stable and mature spacecraft is more reliable and safer

  Earlier, my country has successfully launched 13 Shenzhou spacecraft. What are the functions? Take a look. CCTV CCTV reporter Cui Xia: The height of the Shenzhou spacecraft is 9 meters, and its take -off weight is more than 8 tons. The largest diameter is rice. The top part is called the rail compartment. It is also the living area of ??the astronauts. The supporting equipment of the astronauts in the orbit, including the sensitive device that meets the docking, must be installed in the rail compartment.

When the spacecraft is running alone, it is also where the astronauts live. Gao Xu, the overall chief director of the Human -Ship System of the Five Hospital of Aerospace Science and Technology Group: The main role of the rail compartment is that it is equipped with a lot of sensors to meet and docking, which is responsible for the connection with the space station. Environment in rail life and work. The cabin section in the middle of the spacecraft is the back cabin. It is the only cabin segment that will return to the ground, and it is also the control center of the entire spacecraft.

The control computer of the spacecraft is mainly concentrated in the return cabin, and astronauts take them to and from the world. Gao Xu, the overall chief director of the Human System of the Five Hospital of Aerospace Science and Technology Group: The inside of the cabin is some core control components, including the gesture measurement, the background control of the back cabin. At the same time, some instruments of the astronauts are also returning to the cabin. The spacemen are mainly operating in the return capsule during the independent flight.

  The bottom section of the spacecraft is called a pushing cabin. Here is a spacecraft’s promotion system, power supply, thermal control, measurement and control and other equipment to provide energy, power and communication guarantee for the spacecraft. Yang Huaxing, the overall chief director of the Aerospace Science and Technology Group Eighth Hospital, Yang Huaxing: The engines of the main attitude of the spacecraft flying on track are all promoted. The main power supply is promoting the cabin. After the entire spacecraft is track, its power supply system is to supply power by the energy system of the promotion compartment.

  Adaptability improvement "God 14" is more reliable and secure. According to reports, Shenzhou No. 14 spacecraft fully inherits the technical status of Shenzhou 13 spacecraft, and its main functions and technical indicators remain unchanged. On this basis, according to the task requirements of the space station, the developer has improved the adaptability of Shenzhou 14, making the spacecraft more secure and reliable to escort the life safety of the astronauts. According to reports, the design concept of the Shenzhou manned spacecraft is based on the safety of astronauts. All design and improvements are to ensure that the astronauts are safer and the flight tasks are more reliable.

With the continuous maturity of the manned spacecraft, its equipment and components are constantly upgrading, and the product maturity, quality and reliability of the product are also increasing. Jia Shijin, chief designer of the Fifth Hospital of Aerospace Science and Technology Group: God 14 has done some work from the aspects of localization of raw materials and improved the reliability of products to further enhance the reliability safety of the spacecraft. Xiao Xuedi, the overall supervisor of the Human -Terring System of the Five Hospital of Aerospace Science and Technology Group: Before the manned spacecraft leave the factory and the launch field, the key performance indicators of the spacecraft, the data of the spacecraft that have been successfully flying, and Shenzhou 14th No. 14 The test results of each stage are consistently compared to ensure that its quality is relatively stable.

  According to reports, if an emergency failure occurs during the autonomous flight of the spacecraft, the Shenzhou spacecraft can return to the earth at any time, which can be calculated and returned to the ground personnel under the control of the ground personnel, or it can be returned by the spacecraft autonomous control.

  During the automatic docking process with the space station sky and the core compartment, the Measurement and control equipment faulty of the relative position and relative posture causes the failure of automatic docking.

  During the stop of the space station, if the space station seriously threatened the life of the astronauts, the Shenzhou spacecraft’s ability to evacuate the space station at any time and return to the earth safely. Gao Xu, the overall chief director of the Human -Ship System of the Five Hospital of Aerospace Science and Technology Group: Our key links have carried out redundant backup designs, and there will be no life security of the space staff due to the sudden failure of a device.

At the same time, we have done strict process control for all the dangerous sources, including fireworks and high -pressure gases to ensure the absolute safety of the spacecraft.
