Development of Deceleration and Landing Technology for China's Deep Space Probes
The lunar and planetary exploration programs have propelled the advancement of decel-eration and landing technologies for deep space probes in China,resulting in technological a-chievements represented by unbalance opening load and supersonic sawtooth disk-gap-band para-chutes.This paper discusses the research and application status of deceleration and landing tech-nologies for deep space probes in China's lunar and planetary exploration programs from aspects such as technical specification,system composition,working procedures,aerodynamic decelera-tion scheme and test verification.This paper covers the return and reentry spacecraft of the 3rd phase China lunar exploration program,Chang'e-5,Chang'e-6 and Tianwen-1.Looking forward to the subsequent deep space exploration missions,it is suggested that large-load clustered para-chute deceleration technology be developed to meet the recovery requirements of large-load return module for manned lunar exploration.Hypersonic inflatable entry decelerator technology and low-density supersonic large-load deceleration technology should be developed to satisfy the needs of large load deceleration under low-density environment for Mars sample return missions.Long-duration floating technology for extreme environments should be developed to meet the in-situ at-mospheric floating detections required for Venus exploration missions.
