Future planetary exploration requires spacecraft to land softly on rough terrain and in severe environments. Since conventional landing methods have problems such as high rebounds and excessive resource consumption, the base–extension separation mechanism, which combines springs and separable units, is proposed as a novel landing mechanism. Although the mechanism performed good soft landings, the performance evaluation was limited. Therefore, this study evaluated its performance multilaterally. The proposed technology was analytically compared with two other landing technologies: a generalized-hybrid momentum exchange impact damper and an aluminum foam landing gear. The proposed technology suppressed rebound and acceleration better than the generalized momentum exchange impact damper. Once the components of the proposed technology had been lightened, its energy conversion efficiency matched that of the aluminum foam landing gear. In addition, experiments were conducted using small-scale models to confirm ...read more

Two-Dimensional Experimental Investigation of Base-Extension Separation Mechanism with Telescopic Gear
TL;DR: In this paper, the authors proposed a novel landing mechanism called a telescopic-gear base-extension separation mechanism, which passively adjusts the shape of the landing gear according to the landing terrain and transfers the energy of the lander to a spring as potential energy.
