Abstract
On December 17, 2020, the Chang’e-5 reentry spacecraft landed safely and brought back the lunar sample without damage. This paper describes the recovery system that has critically contributed to the scientific success of the Chang’e-5 missions and presents the technical requirements and constraints of the recovery system for the Chang’e-5 reentry spacecraft and discusses the design process of the recovery system, including the system composition, working procedure, and some other key aspects. Finally, the ground cover rejection tests and air drop and flight tests were carried out to confirm the design configuration. The results showed that the Chang’e-5 reentry spacecraft recovery system was designed correctly, and its functions and performances met the design requirements. A breakthrough in the recovery technology of the reentry spacecraft was achieved for Chinese first lunar sample-return mission.
期刊介绍：
"China Space Science and Technology" is sponsored by the China Academy of Space Technology. It is an academic and technical journal that comprehensively and systematically reflects China's spacecraft engineering technology. The purpose of this journal is to "exchange scientific research results, explore cutting-edge technologies, activate academic research, promote talent growth, and serve the space industry", and strive to make "China Space Science and Technology" a first-class academic and technical journal in China.
This journal follows the principle of "let a hundred flowers bloom and a hundred schools of thought contend", promotes academic democracy, and actively carries out academic discussions, making this journal an important platform for Chinese space science and technology personnel to publish research results, conduct academic exchanges, and explore cutting-edge technologies; it has become an important window for promoting and displaying China's academic achievements in space technology.
