| Abstract: |
Exploring extraterrestrial planet is a common dream of humanity. Since the 1960s, planetary exploration technology has begun to thrive. The soft landing buffer system is one of the critical devices of the planetary probe. It is mainly used to absorb the impact energy when the planetary probe lands, reduce the impact overload of the astronauts, lander structure, and payload, and ensure the probe's and astronauts' safe landing. Therefore, the soft landing buffer system is vital in determining whether the planetary probe can land safely. This study reviews and discusses the related research work on soft landing buffer systems. Firstly, the representative planetary exploration missions are summarized, and the soft landing buffer systems used in these missions are analyzed and discussed. Then, according to the development history of the landing buffer system, this review first introduces the components of the airbag cushioning system, and then discusses the working principle as well as the engineering implementation of three types of airbag cushioning system, i.e. non-vented airbag, vented airbag, and combined airbag. Next, the legged landing gear was detailedly introduced and discussed. The working principle of common energy-absorbing structures in legged landing gear, including hydraulic shock absorber, plastic deformation energy-absorbing structure such as honeycomb, thin-walled metal tube, electromagnetic shock absorber, and metal pull rod, is focused on. Subsequently, new soft landing buffer system such as Sky Crane, magnetorheological landing gear and smart airbag system were discussed, and related research work was summarized. Finally, the future development direction of soft landing buffer system for planetary probe is discussed. • The landing buffer systems used in the completed planetary exploration are summarized. • The working principle, structural form, and characteristics of the various landing buffer systems are introduced. • The research progress of the typical landing buffer systems and cushioning components is reviewed in detail. • The existing problems and future development directions of landing buffer systems are discussed.
