China News Service, October 16 (Zheng Yingying, Marshal Sha Guo Chaokai) The Shenzhou 13 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center in the early morning of the 16th to succeed its "brother"-Shenzhou 12 continues to operate the China Space Station Manned missions during the construction phase.

How will "Shenzhou 13" "continue power"?

The developers revealed the exclusive secret of "Space Charging".

  Tang Xiao, deputy director designer of the Shenzhou spacecraft power subsystem of the 811 Institute of the Eighth Academy of China Aerospace Science and Technology Corporation, introduced that the entire China space station system-the three compartments of the space station, the Shenzhou spacecraft and the cargo spacecraft, their power sources can transmit and complement each other. of.

  Tang Xiao further explained that, in order to ensure the safety of the astronauts, the Shenzhou spacecraft, which uses a low-voltage power supply system for the mission, will serve as the power receiving terminal and receive grid-connected power supply from the space station. The grid-connected power supply test of the core cabin of the space station received power supplement from the core cabin. We respectively verified the working conditions of the spacecraft with different loads and different power generation capacity combinations, covering the alternating changes in the illuminated area and the shaded area, and fully assessed the grid connection The power supply function and the correctness of the grid-connected control strategy."

  Zhong Danhua, the chief designer of the Shenzhou spacecraft power supply subsystem of the 811 Institute of the Eighth Academy of China Aerospace Science and Technology Corporation, introduced that in order to allow the Shenzhou spacecraft to participate in the joint power supply in a more reliable state, the developers have further carried out a series of work to improve the reliability of power products. The launch site has carried out the deployment, testing and related work of the solar wing under the whole ship state, so that the solar battery wing has the ability to deploy, close and test under the whole ship state.
